|
||
- FIX: Fixed timeout problem in the lwIP interface layer (bug 3302420)
|
||
(backported to 2.2.4).
|
||
- NEW: New I2C driver model and STM32 implementation.
|
||
(evaluate the option to change the API to a synchronous model)
|
||
- NEW: New RTC driver model and STM32 implementation.
|
||
(API and functionality review)
|
||
- NEW: Improved MAC driver model, it now follows the same template of other
|
||
drivers.
|
||
(uIP demo to be adapted)
|
||
(implement macStop() in AT91SAM7X implementation)
|
||
- NEW: New RCC helper driver for STM32F1xx and STM32L1xx, it simplifies
|
||
the use of the RCC resources and hides most differences found among the
|
||
various STM32 sub-families.
|
||
- NEW: New DMA helper driver for STM32, it simplifies the use of the DMA
|
||
resources and hides most differences with the new enhanced DMA units
|
||
found in the STM32F2xx sub-family.
|
||
- NEW: Now an error is generated at compile time when trying to enable the
|
||
options CH_DBG_ENABLE_STACK_CHECK on ports that do not support it.
|
||
- NEW: Added a kernel-only Cortex-Mx demo as reference project for users not
|
||
interested in the HAL but just want to use the ChibiOS/RT kernel.
|
||
The demo is named ARMCM3-GENERIC-KERNEL and is defaulted to the STM32, in
|
||
order to use it on other families or on the ARM Cortex-M0 just change the
|
||
inclusion paths in the makefile.
|
||
- NEW: Integrated new FatFs version 0.8b.
|
||
- NEW: Added a new hook THREAD_CONTEXT_SWITCH_HOOK() that allows to insert
|
||
code just before a context switch. For example this hook could be used
|
||
in oder to implement advanced power management schemes.
|
||
- NEW: Added a new debug option CH_DBG_SYSTEM_STATE_CHECK that ensures the
|
||
correct API call protocol. If an API is invoked out of the correct context
|
||
then the kernel panics with a debug message.
|
||
- NEW: Added Eclipse ChibiOS/RT debugger plugin 1.0.5 under ./tools/eclipse.
|
||
- NEW: The ARMCMx startup file (crt0.c) now is able to fill the stack areas
|
||
with a filler (default behavior). This is required in order to easily assess
|
||
the stack usage at runtime.
|
||
- NEW: Added the new CMSIS 2.1 headers, now CMSIS resides into a shared
|
||
location: ./os/ports/common/ARMCMx/CMSIS. Old CMSIS files have been
|
||
removed from the various platforms.
|
||
- NEW: Removed all the ch.ld files from the ARMCMx demos, now the makefiles
|
||
point to common ld files under the various ports. Less duplication and
|
||
easier maintenance.
|
||
- NEW: Improved stack checking and reorganized memory map for the Cortex-Mx
|
||
demos. Now stacks are allocated at the start of the RAM, an overflow of the
|
||
exception stack now triggers an exception (it could went unnoticed before).
|
||
The process stack is organized to be checked on context switch like other
|
||
threads. Now all threads have an explicit stack boundary pointer.
|
||
(TODO: documentation to be updated)
|
||
- NEW: Added debug plugin for Eclipse under ./tools/eclipse (backported to
|
||
2.2.7).
|
||
- NEW: The debug macros chDbgCheck() and chDbgAssert() now can be externally
|
||
redefined. The macro chDbgCheck() no more includes the line number in the
|
||
description because incompatibility with the Cosmic compiler (backported to
|
||
2.2.7).
|
||
- NEW: Added provisional support for STM32L1xx and STM32F2xx. Because of this
|
||
some directories related to the STM32 have been renamed, your makefiles may
|
||
require adjustments.
|
||
(TODO: change to be ported to IAR and Keil build files)
|
||
- NEW: Added a custom rule to the various rules.mk files, now it is possible
|
||
to add an user rule into the Makefiles.
|
||
- NEW: Improvements to the trace buffer, now it stores a full thread pointer
|
||
and event time, changed names to debug variables by adding the "dbg_"
|
||
prefix (backported to 2.2.7).
|
||
- NEW: Added a new functionality to the registry subsystem, now it is possible
|
||
to associate a name to the threads using chRegSetThreadName. The main and
|
||
idle threads have their name assigned by default (backported to 2.2.7).
|
||
- NEW: Added TIM8 support to the STM32 GPT, ICU and PWM drivers.
|
||
- NEW: Updated the STM32 header file to the latest version 3.5.0 and fixed
|
||
it in order to correct several bugs related to the XL family.
|
||
- NEW: Added a chprintf() function to ./os/various, it can print on any
|
||
BaseChannel.
|
||
- NEW: Improved the mini shell, enhanced info command, optimizations and
|
||
removed the shellPrint() and shellPrintLine() functions, now it uses
|
||
chprintf() for output.
|
||
- NEW: lwIP 1.4.0 has been integrated, this new version does not require
|
||
custom hooks into the Thread structure and is thus much lighter.
|
||
- NEW: FatFs demo for the STM32F103ZG using the SDC driver.
|
||
- NEW: Now the STM32 SDC driver supports unaligned buffers transparently.
|
||
Optimized the driver for single block read and write operations. Optimized
|
||
the driver state machine.
|
||
- NEW: Finished the reorganization of the Cortex-Mx ports, now also the
|
||
IAR and RVCT ports support the new Compact mode.
|
||
- NEW: Added to the ARMv6-M sub-port an option to use the PendSV exception
|
||
instead of NMI for preemption (backported to 2.2.5).
|
||
- NEW: Reorganization of the Cortex-Mx ports in order to reduced code and
|
||
comments duplication in the various headers (backported to 2.2.5).
|
||
- NEW: Improved the ARMv7-M sub-port now there are two modes: Compact and
|
||
Advanced.
|
||
The advanced mode is equivalent to the previous versions, the compact mode
|
||
is new and makes the kernel *much* smaller and generally faster but does
|
||
not support fast interrupts (backported to 2.2.5).
|
||
- NEW: Now the port layer exports info regarding the compiler and the port
|
||
options. The info are printed into the test reports.
|
||
- CHANGE: Removed the option CH_USE_NESTED_LOCK, lwIP no more requires it and
|
||
it would have conflicted with CH_DBG_SYSTEM_STATE_CHECK which is far more
|
||
useful.
|
||
- CHANGE: Renamed the scheduler functions chSchIsRescRequiredExI() to
|
||
chSchIsPreemptionRequired(), chSchDoRescheduleI() to chSchDoReschedule(),
|
||
chSysSwitchI() to chSysSwitch(). All those functions were special cases
|
||
and not regular I-class APIs.
|
||
- CHANGE: Renamed the macros IDLE_THREAD_STACK_SIZE and INT_REQUIRED_STACK
|
||
to PORT_IDLE_THREAD_STACK_SIZE and PORT_INT_REQUIRED_STACK for consistency.
|
||
- CHANGE: Removed the "old" Cortex-M3 port from the code, the current port
|
||
has no drawbacks and the old port is now just a maintenance cost.
|
||
- CHANGE: Removed the CH_CURRP_REGISTER_CACHE option, it is GCC-specific so
|
||
it does not belong to the kernel options. The feature will be eventually
|
||
reimplemented as a port-specific option.
|
||
- CHANGE: chiQGetFullI() and chOQGetFullI() become macros. The queues
|
||
subsystem has been optimized and is no more dependent on semaphores.
|
||
Note that the queues callbacks invocation policy has been slightly
|
||
changed, see the documentation (backported to 2.2.4).
|
||
|
||
*** 2.3.2 ***

||
- FIX: Fixed invalid BRR() macro in AVR serial driver (bug 3299306)(backported
|
||
to 2.2.4).
|
||
- FIX: Fixed missing IRQ vectors amicable names for STM32 XL devices (bug
|
||
3298889)(backported to 2.2.4).

|
||
to 2.2.4).
|
||
- FIX: Fixed wrong macro check for STM32 XL devices (bug 3291898)(backported
|
||
to 2.2.4).
|
||
- FIX: Fixed SPI driver restart in STM32 SPI driver implementation, also
|
||
applied the same fix to the STM8S SPI driver (bug 3288758)(backported to
|
||
2.2.4).
|
||
- FIX: Fixed missing state transition in ADC driver (bug 3288149)(backported
|
||
to 2.2.4).
|
||
- FIX: Fixed missing state transition in SPI driver (bug 3288112)(backported
|
||
to 2.2.4).
|
||
- FIX: Fixed spurious characters generated by Serial over USB driver (bug
|
||
3276379).
|
||
- NEW: Added an option to the kernel to not spawn the Idle Thread from within
|
||
chSysInit(), this way the application can spawn a custom idle thread or
|
||
even use the main() thread as idle thread (backported to 2.2.4).
|
||
- NEW: Added new SDC driver model, Secure Digital Card.
|
||
- NEW: SDC driver implementation for STM32.
|
||
- NEW: Updated the STM32 header file to the latest version 3.4.0, had to
|
||
fix a bug regarding the STM32 XL sub-family.
|
||
- NEW: New unified GCC startup file for Cortex-Mx processors, it is written
|
||
in C instead of asm and supports constructors/destructors. Improved the
|
||
Cortex-Mx linker scripts in all the GCC demos.
|
||
- NEW: Now it is possible to share DMA channels in the STM32 HAL thanks
|
||
to a centralized manager. Channels are allocated when the driver is
|
||
started and released when it is stopped.
|
||
- NEW: Added an STM32 C++ demo for the GNU compiler.
|
||
- NEW: Added an STM32F103ZG demo for the STM3210E-EVAL evaluation board.
|
||
|
||
- OPT: STM32 PWM driver implementation simplified.
|
||
- CHANGE: Now pwmChangePeriod() does not implicitly disable the active
|
||
PWM channels.
|
||
- CHANGE: Renamed the chSemSetCounterI() function to chSemAddCounterI() and
|
||
changed its behavior.
|
||
- CHANGE: Modified the STM32 USB-CDC test demo to spawn a shell over the USB
|
||
serial connection.
|
||
|
||
*** 2.3.1 ***
|
||
- FIX: Fixed insufficient idle thread stack in Cortex-M0-GCC port (bug 3226671)
|
||
(backported to 2.2.3).
|
||
- FIX: Fixed stack checking in Cortex-M0-GCC port (bug 3226657)(backported
|
||
to 2.2.3).
|
||
- FIX: Fixed wrong checks in PAL driver (bug 3224681)(backported to 2.2.3).
|
||
- FIX: Fixed wrong checks in I/O Queues (bug 3219197)(backported to 2.2.3).
|
||
- FIX: Fixed invalid assertion in adcConvert() (bug 3205410)(backported
|
||
to 2.2.3).
|
||
- NEW: Improvements to the PWM driver model:
|
||
- Easier configuration similar to the GPT driver initializations, macros
|
||
are no more required.
|
||
- Added a new function that allows to change the PWM period on the fly,
|
||
even from within callbacks. Formerly it was required to stop and restart
|
||
the driver.
|
||
- Improved driver documentation.
|
||
- NEW: Added advanced mode to the STM32 PWM driver (TIM1 only).
|
||
- NEW: Added new ICU driver model, Input Capture Unit.
|
||
- NEW: ICU driver implementation for STM32.
|
||
- NEW: Implemented stack checking in the Cortex-Mx RVCT port (backported
|
||
to 2.2.3).

|
||
mcuconf.h file is changed for STM32F105/STM32F107 devices.
|
||
- NEW: Added board files for the Olimex STM32-P107.
|
||
- NEW: Improved setup packets handling in the USB driver through a specific
|
||
callback.
|
||
- NEW: Improvements to the PAL driver and various implementation in order
|
||
to make them more parenthesis friendly.
|
||
- OPT: Simplified Serial over USB driver configuration.
|
||
- CHANGE: Renamed the demo ARMCM3-STM32F107-GCC in ARMCM3-STM32F107 and added
|
||
IAR and Keil projects.
|
||
- CHANGE: Now the ARMCM3-STM32F107 demo targets the board Olimex STM32-P107
|
||
as default.
|
||
- CHANGE: Removed all the prefixes from the structure/union field names
|
||
in the HAL subsystem.
|
||
- CHANGE: Updated the documentation to use Doxygen 1.7.4 which produces a much
|
||
more readable output. Also modified the documentation layout to put functions
|
||
and variables ahead of everything else in the group pages.
|
||
Doxygen version below 1.7.4 cannot be used anymore because differences in
|
||
templates. Note that now there are two Doxygen projects, one for generating
|
||
the CHM file the other for plain HTML.
|
||
|
||
*** 2.3.0 ***
|
||
- FIX: Fixed race condition in CM0 ports, the fix also improves the
|
||
ISR latency (bug 3193062)(backported to 2.2.2).
|
||
- FIX: Fixed Cortex-Mx linker scripts alignment of __heap_base__, the
|
||
correct alignment is now enforced at runtime into core_init() in order
|
||
to make the OS integration easier (bug 3191112)(backported to 2.2.2).
|
||
- FIX: Fixed error in function chCoreAllocI() function documentation (bug
|
||
3191107)(backported to 2.2.2).
|
||
- FIX: Fixed minor problem with memory pools (bug 3190512)(backported to
|
||
2.2.2).
|
||
- FIX: Stack overflow in CM0 ports when nearing interrupts saturation (bug
|
||
3187105)(backported to 2.2.1).
|
||
- FIX: Fixed error in _BSEMAPHORE_DATA macro (bug 3184139)(backported to
|
||
2.2.1).
|
||
- FIX: Error in MAC driver (bug 3179783)(backported to 2.2.1).
|
||
- FIX: Fixed wrong serial driver macros (bug 3173336)(backported to 2.2.1).
|
||
- NEW: Improved preemption implementation for the Cortex-M0, now it uses
|
||
the NMI vector in order to restore the original context. The change makes
|
||
IRQ handling faster and also saves some RAM/ROM space. The GCC port code
|
||
now does not inline the epilogue code in each ISR saving significant ROM
|
||
space for each interrupt handler in the system (backported to 2.2.3).
|
||
- NEW: Added "IRQ STORM" long duration tests for the STM32, LPC11xx and
|
||
LPC11xx. The test demonstrates the system stability in a thread-intensive,
|
||
progressively CPU-saturating, IRQ-intensive long duration test.
|
||
- NEW: Added two new functions to the events subsystem: chEvtBroadcastFlags()
|
||
and chEvtBroadcastFlagsI(). The old chEvtBroadcast() and chEvtBroadcastI()
|
||
become macros. The new functions allow to add the same flags to all the
|
||
registered listener threads.
|
||
- NEW: Added I-Class functions to the MailBoxes subsystem, now it is
|
||
possible to use them as a transport layer between ISRs and Threads
|
||
(backported to 2.2.2).
|
||
- NEW: Added new USB driver model, probably it will evolve in next
|
||
releases.
|
||
- NEW: USB driver implementation for STM32.
|
||
- NEW: Added "serial over USB" driver, it implements a Communication
|
||
Device Class exposing it as a normal serial driver to applications,
|
||
probably it will evolve in next releases.
|
||
- NEW: Added STM32 USB CDC loopback test application.
|
||
- NEW: Added new GPT driver model, General Purpose Timer. The driver
|
||
allows to access the available timers in an abstract way.
|
||
- NEW: GTP driver implementation for STM32, LPC13xx and LPC11xx.
|
||
- NEW: Added STM32 GPT test application.
|
||
- NEW: Implemented new event IO_TRANSMISSION_END in the generic serial
|
||
driver. This event marks the physical transmission end of a data stream.
|
||
- NEW: Implemented the new IO_TRANSMISSION_END event in the STM32 serial
|
||
driver.
|
||
- NEW: Added explicit reset of all peripherals inside the STM32 HAL driver.
|
||
Removed the separate resets on initialization from the various other
|
||
drivers saving significant space.
|
||
- OPT: Removed TIMx reset on system startup in the STM32 PWM driver, the
|
||
timers are already reset on driver startup.
|
||
- CHANGE: The functions chEvtSignal() and chEvtSignalI() have been renamed
|
||
to chEvtSignalFlags() and chEvtSignalFlagsI() for consistency.
|
||
- CHANGE: Swapped the numeric values of the TIME_IMMEDIATE and TIME_INFINITE
|
||
constants. Fixed the relative documentation in various places (backported
|
||
to 2.2.2).
|
||
- Many documentation improvements.
|
||
|
||
*** 2.1.8 ***
|
||
- FIX: Fixed error in STM32 ADC driver macro names (bug 3160306)(backported
|
||
to 2.0.11).
|
||
- FIX: Fixed IAR Cortex-Mx port memory organization problem (bug 3158776).
|
||
- FIX: Fixed STM32F103 demo's incorrect clock settings (bug 3153746).
|
||
- NEW: Added OTG clock setting to the STM32 HAL.
|
||
- NEW: Added stack check support to the IAR Cortex-Mx port.
|
||
- CHANGE: Removed .uvopt files from the Keil projects.
|
||
|
||

|
||
(backported to 2.0.9).
|
||
- FIX: Fixed extra notifications in input queues (bug 3148525)(backported
|
||
to 2.0.9).
|
||
- NEW: New ARM Cortex-Mx port for RVCT compiler.
|
||
- NEW: Integrated the various Cortex-Mx GCC, IAR and RVCT demos in unified
|
||
demos with multiple project files, the code is exactly the same. Renamed
|
||
the directories removing the compiler suffix.
|
||
- NEW: Added an USB clock configuration in the STM32 HAL driver (LD, MD, HD).
|
||
- NEW: New semaphore API chSemSetCounterI().
|
||
- NEW: New queue APIs chIQGetFullI() and chOQGetFullI().
|
||
- CHANGE: Serial drivers now have a single event source instead of three,
|
||
the event source is located in the superclass, this allows to create
|
||
alternative implementations of the serial driver while keeping compatibility,
|
||
the change also allowed to save 8/4 RAM bytes per serial driver.
|
||
- CHANGE: Modified the ADC and CAN drivers to allow a NULL pointer for
|
||
the configuration structure if it is not required by the implementation.
|
||
- CHANGE: Modified the MMC_SPI driver to *require* a NULL as pointer to
|
||
the configuration.
|
||
- CHANGE: Removed enforced inlining for the chSchReadyI() function when
|
||
the CH_OPTIMIZE_SPEED is enabled. Now the matter is left to the compiler
|
||
specific settings. This change is meant to increase compatibility with
|
||
compilers that have a different inlining semantic than GCC when not in
|
||
C99 mode.
|
||
- CHANGE: Changed the declaration of the main() function in all demos
|
||
without arguments. Removed the clearing of arguments from the startup
|
||
files and saved some space.
|
||
- CHANGE: Queues callbacks now have as parameter a pointer to the queue,
|
||
there were no parameters previously.
|
||
- Documentation related fixes.
|
||
|
||
*** 2.1.6 ***

register in the upper half word of the can status word for easier
|
||
debug.
|
||
- CHANGE: Changes in the board files organization, now the board
|
||
initialization is invoked from within halInit() after all the device
|
||
drivers have been initialized. Now applications are required to
|
||
explicitly invoke halInit() and chSysInit() from within their main().
|
||
- CHANGE: Removed the CMSIS files from the ARMCMx port, added the headers
|
||
into the various HAL platforms requiring them. The change is required
|
||
because the port layer must not have vendor specific dependencies and
|
||
there is the possibility that the various vendors would use different
|
||
CMSIS versions now that CMSIS 2.x has been released.
|
||
- CHANGE: Modified the start of the ADC in the STM32 ADC driver, now it is
|
||
no more required to specify ADC_CR2_EXTSEL_SWSTART and ADC_CR2_CONT
|
||
in the CR2 register configuration. Also reordered the start sequence
|
||
in order to allows a longer stabilization time for the ADC.
|
||
- Documentation improvements.
|
||
|
||

|
||
macros in order to accomodate different implementations without have to
|
||
change the port layer.
|
||
- CHANGE: Modified the STM32_PWM_PWMx_IRQ_PRIORITY macros in the STM32
|
||
PWM driver (and all the STM32 mcuconf.h files) and renamed them in
|
||
STM32_PWM_TIMx_IRQ_PRIORITY for consistency.
|
||
- Documentation related fixes.
|
||
|
||
*** 2.1.4 ***

- CHANGE: Improved the STM32 HAL to support multiple sub-families, at compile
|
||
time now it is possible to test the presence of any single peripheral into
|
||
the specified STM32 device.
|
||
- CHANGE: Separated dynamic threads code into dedicated files: chdynamic.c
|
||
and chdynamic.h.
|
||
- CHANGE: Moved the declaration of the variable pal_default_config from
|
||
hal_lld.c to the various board.c. That structure is more meaningful in
|
||
the board layer because it is related to the board initialization.
|
||
- CHANGE: Removed the various assembler files for the STM32 interrupt
|
||
vectors, now it is a single vectors.c file.
|
||
- CHANGE: Deleted ./os/ports/GCC/ARM.
|
||
- CHANGE: Renamed ./os/ports/GCC/ARM7 in ./os/ports/GCC/ARM.
|
||
- CHANGE: Renamed ./os/hal/platforms/STM8 in ./os/hal/platforms/STM8S.

||
- NEW: Added an SPI driver to the STM8 platform support.
|
||
- NEW: Added a simple STM8 SPI demo under ./testhal/STM8/SPI.
|
||
- NEW: Divided the file STM32/vectors.s in several files, one for each

||
STM32 sub-family. This has been done in order to remove the preprocessor
|
||
directives from assembler files and to support all the various STM32
|
||
sub-families.
|
||
- CHANGE: Renamed ./os/ports/GCC/ARMCMx/STM32F10x in STM32.
|
||
- CHANGE: Divided the file ARMCMx/crt0.s in crt0_v6m.s and crt0_v7m.s in
|
||
order to remove the preprocessor directives from assembler files.
|
||
- CHANGE: Renamed the HAL settings macro names, removed the CH_ prefix
|
||
because it is reserved for the kernel namespace.

- NEW: New I2C driver model (not complete and no implementations yet).
|
||
- NEW: New SPI driver model, the new model supports both synchronous and
|
||
asynchronous operations and, in general, simplifies the implementation of the
|
||
low level driver. The new driver also specifies a simplified polled exchange
|
||
API, useful for efficiently sending small amount of data over high speed
|
||
connections. The driver state diagram changed slightly changed so be careful.
|
||
- NEW: New ADC driver model, the new model supports both synchronous and
|
||
asynchronous operations and, in general, simplifies the implementation of the
|
||
low level driver. The driver state diagram changed slightly changed so be
|
||
careful.
|
||
- NEW: Improved PWM driver model, added several macros that helps to setup
|
||
configuration structures and to specify pulse widths also as percentages or
|
||
degrees using a fixed point notation. Added new pwmEnableChannelI() and
|
||
pwmDisableChannelI() APIs in order to allow channel reprogramming from
|
||
within callbacks or interrupt handlers, the new APIs are implemented as
|
||
macros so there is no footprint overhead.
|
||
- NEW: Added driver fields and initialization hooks for the callback-based
|
||
drivers. The hooks are named XXX_DRIVER_EXT_FIELDS and
|

|
||
not yet transferred frames when stopping an operation.

|
||
- NEW: New kernel APIs chSysGetIdleThread() and chThdGetTicks(), the new
|
||
APIs are simple macros so there is no footprint overhead.
|
||
- NEW: Added a generic BaseFileStream interface for future File System
|
||
implementations or integrations (untested and not sure if it will stay or
|
||
change).
|
||
- NEW: Added to the documentation more notes about interrupt handlers in
|
||
the ARM7 port.
|
||
- NEW: Modified some tests in order to bring back code coverage to 100%
|

in all modules except chdebug.c. Added a test case covering binary
|
||
semaphores.
|
||
- OPT: The fix to the bug 3075544 considerably improved the threads creation
|
||
benchmarks score.
|
||
- OPT: Speed optimizations to the STM32 SPI driver, greatly improved latency.
|
||

|
||
make clear it is usable from interrupt handlers.
|
||
- CHANGE: The mailboxes macros chMBSize(), chMBGetEmpty(), chMBGetFull(),
|
||
chMBPeek() have been renamed to chMBSizeI(), chMBGetFreeCountI(),
|
||
chMBGetUsedCountI(), chMBPeekI().
|
||
- CHANGE: The queue APIs chQSize(), chQSpace(), chIQIsEmpty(), chIQIsFull(),
|
||
chOQIsEmpty(), chOQIsFull() have been renamed to chQSizeI(), chQSpaceI(),
|
||
chIQIsEmptyI(), chIQIsFullI(), chOQIsEmptyI(), chOQIsFullI().
|
||
- CHANGE: The event APIs chEvtPend() and chEvtClear() have been renamed
|
||
to chEvtAddFlags() and chEvtClearFlags() for consistency and correct
|
||
English. Changed the macro chEvtIsListening() in chEvtIsListeningI().
|
||
- CHANGE: Added a parameter to the PWM driver callbacks, the pointer to the
|
||
driver itself.
|
||
- CHANGE: Added a parameter to the UART driver callbacks, the pointer to the
|
||
driver itself.
|
||
- CHANGE: In the UART driver now an error does not automatically brings the
|
||
receiver in UART_RX_IDLE state, the receive operation continues unless
|
||
explicitly stopped in the error callback handler. This considerably
|
||
simplifies the low level driver code.
|
||
- CHANGE: Removed a spurious trailing ; after the WORKING_AREA() macro
|
||
declaration in several ports. The ; should go after the macro invocation.

****** this version in your project. ******
|
||
- CHANGE: Renamed the existing system hooks by adding the _HOOK suffix to
|
||
the name in order to make names more consistent.

****** this version in your project. ******
|
||
- CHANGE: Extensive documentation improvements, fixed terminology in the
|
||
events related documentation and articles.
|
||
- CHANGE: The documentation is no more included in the distribution, the
|
||
file ./documentation.html redirects to the online documentation page
|
||
that contains *much* better documents.
|
||
Note that it is still possible to generate the local documentation using
|
||
Doxygen, the procedure is very simple and described in ./docs/readme.txt.

- FIX: Fixed misspelled word in some chioch.h and chstreams.h macros (bug
|
||
3031534)(backported to 2.0.3).
|
||
- FIX: Fixed wrong macro check in the STM32 SPI driver (bug 3028562)(backported
|
||
to 2.0.3).
|
||
- FIX: Fixed invalid context restore in MSP430 port (bug 3027975)(backported
|
||
to 2.0.2).

|
||
3025549)(backported to 2.0.2).
|
||
- FIX: Added option to enforce the stack alignment to 32 or 64 bits in the
|
||
Cortex-Mx port (bug 3025133)(backported to 2.0.2).
|
||
- NEW: Centralized DMA macros in the STM32 HAL.
|
||
- NEW: New UART device driver model, this device driver allows unbuffered,
|
||
callback driven access to UART-type devices.
|
||
- NEW: UART device driver for STM32 and UART demo application under
|
||
./testhal/STM32/UART.
|
||
- NEW: Added friendly interrupt vectors names to the STM32 HAL (change request
|
||
3023944).
|
||
- NEW: Added support for SPI3 in the STM32 HAL.
|
||
- CHANGE: Redeclared the IRQ handlers in the various STM32 drivers using the
|
||
new friendly vector names.
|
||
- CHANGE: Moved the STM32 HAL stess test application under
|
||
./testhal/STM32/_stress_test.
|
||
- CHANGE: Removed the option -mabi=apcs-gnu from all the Cortex-Mx demos. The
|
||
option is not compatible with the 64 bits stack alignment now default in
|
||
the Cortex-Mx port. Note that the 64 bits alignment has a cost both as
|
||
performance and as space but it is the "standard".
|
||
- OPT: Small speed optimization in the STM32 SPI driver.
|
||
- OPT: Optimized DMA clearing in STM32 ADC and SPI drivers, there was no need
|
||
to read/modify/write the IFCR DMA register, it is write only.
|
||
- Fixed various documentation errors.
|
||
|
||
*** 2.1.0 ***
|
||
- FIX: Fixed notification order in input queues (bug 3020708)(backported in

2.0.1).
|
||
- FIX: Fixed non functional CH_CURRP_REGISTER_CACHE option in the Cortex-M3
|
||
port (bug 3020702)(backported in 2.0.1).
|
||
- FIX: Fixed non functional CH_DBG_ENABLE_STACK_CHECK option in the Cortex-M3
|
||
caused by GCC 4.5.0, the fix also improves the context switch performance
|
||
because GCC 4.5.0 apparently was generating useless instructions within the
|
||
very critical context switch code (bug 3019738)(backported in 2.0.1).
|
||
- FIX: Fixed insufficient stack space assigned to the idle thread in
|
||
Cortex-M3 port (bug 3019594)(backported in 2.0.1).

|
||
- FIX: Fixed assertion in adcStop() (bug 3015109)(backported in 2.0.0).
|
||
- NEW: Merged the new unified STM8 port, now the port supports both the
|
||
Cosmic and Raisonance compilers.
|
||
- NEW: Added an STM8-DISCOVERY demo, the demo can be compiled with both the
|
||
Cosmic and Raisonance compilers under the STDV IDE. Performance reports
|
||
have been added for both compilers.
|
||
NOTE: The Raisonance compiler seems to have problems in debugging under
|
||
the STDV IDE, if you need to debug using the Raisonance compiler
|
||
consider using the RIDE7 IDE instead.
|
||
Compiling and executing using the "release" mode under STDV works fine.
|
||
- NEW: Added timers clock macros to the STM32 clock tree HAL driver (backported
|
||
in 2.0.1).
|
||
- NEW: Added Binary Semaphores among the synchronization primitives. The new
|
||
subsystem is entirely implemented as macros over the existing and proven
|
||
Counting Semaphores thus takes no space (experimental).
|
||
- NEW: Added a simplified SPI driver for AT91SAM7 devices, contributed by
|
||
Alexander (experimental).
|
||
- NEW: Added FatFs demos for AT91SAM7S and AT91SAM7X, contributed by
|
||
Alexander (experimental).
|
||
- OPT: Simplified the test suite code, now it is smaller.
|

|
||
is FALSE.
|
||
- OPT: Small size optimization in the semaphores subsystem.
|
||
- OPT: Improvements in the STM8 port, the code is now smaller and generally
|
||
faster, also saved few bytes of RAM.
|
||
- Added explicit casts in chevents.h, chqueues.h, chqueues.c in order to
|
||
silence some warnings on a specific compiler.
|
||
- Added a section in chconf.h where redefine the port-related configuration
|
||
parameters, also added notes into the documentation about this.
|
||

3005628)(backported in 1.4.4).
|
||
- FIX: Fixed wrong inclusion order of board.h and halconf.h into hal.h
|
||
(bug 3005041)(backported in 1.4.4).
|
||
- FIX: Fixed wrong GPIO ports size in the STM8 PAL driver (bug 3001528).
|
||
- NEW: Improved clock initialization for the STM32, now it is possible to
|
||
configure the clock using any clock source and any HSE frequency.
|
||
- NEW: The STM32 clock tree parameters and checks are now calculated into
|
||
a separate file in order to support multiple clock trees for different
|
||
sub-families of the STM32 platform.
|
||
- NEW: Added separated clock trees for the STM32 LD/MD/HD sub-family and
|
||
the CL sub-family. Now the selection of the sub-family is done in the
|
||
board.h file, there is no more the need to put -DSTM32F10X_xx into
|
||
the makefile.
|
||
- NEW: Added the palSetBusMode() capability to the STM8 PAL driver.
|
||
- NEW: Added the palSetBusMode() capability to the LPC11xx and LPC13xx
|
||
PAL drivers.
|
||
- NEW: Updated the STM32 FW Library files to latest version 3.3.0.
|
||
- CHANGE: Renamed the STM32, STM8, LPC214x, AT91SAM7x, MSP430 and simulators
|
||
PAL configuration structures to PALConfig, it is better to have the same
|
||
name for this structure in all ports (like for all the other drivers).
|
||
- CHANGE: Modified the linker scripts in the ARM demos in order to increase
|
||
compatibility with the CodeSourcery toolchain.
|
||
- Tested the STM8 port with the latest RKit-STM8_2.28.10.0092. It works but
|
||
the new compiler shows a slight performance regression except in one
|
||
test case.
|
||
- Added credits page to the documentation, improved the article regarding
|
||
timings.
|
||
- Performed another documentation revision cycle, fixed more bad English and
|
||
few errors.
|
||
|
||
*** 1.5.6 ***
|
||
- FIX: Fixed centralized ARM makefile (bug 2992747)(backported in 1.4.3).
|
||
- FIX: Fixed write problems in MMC_SPI driver (bug 2991714)(backported in
|
||
1.4.3).
|
||
- FIX: Fixed wrong macros in chioch.h (bug 2989468).
|
||
- FIX: Fixed wrong macro check in serial.h (bug 2989459)(backported in 1.4.3).
|
||
- NEW: Added a ROMCONST macro in chtypes.h, this macro must be used for
|
||
constant that must be placed in code space, it should not be assumed that
|
||
the "const" keyword does that. Note that this macro is not used to place
|
||
constants in different address spaces (AVR) because it is assumed that a
|
||
pointer to a ROMCONST variable is compatible with a normal pointer.
|
||
- NEW: AT91SAM7 HAL support for the DGBU UART peripheral, as SD3.
|
||
- NEW: Introduced a new macro CH_FAST_IRQ_HANDLER() for the declaration of
|
||
fast interrupt handlers on those architectures that support them.
|
||
- OPT: Internal optimization in the serial driver, it now is a bit smaller
|
||
and uses less RAM (all architectures).
|
||
- CHANGE: Modified the STM32 FatFs demo, now it spawns a command shell or
|
||
the serial port SD2, type "help" for the available commands. More commands
|
||
can be easily added.
|
||
- CHANGE: Renamed the chCoreFree() function in chCoreStatus() because it
|
||
might be mistaken for a function that frees memory.
|
||
- CHANGE: All ARM demos makefiles now defaults to arm-none-eabi- GNU
|
||
toolchains because the latest YAGARTO now uses that setting. It is still
|
||
possible to use arm-elf- toolchains by editing the TRGT variable in the
|
||
makefiles.
|
||
- Various documentation fixes, added new articles covering debugging under
|
||
ChibiOS/RT, OS integration, OS stop and restart. Updated the article about
|
||
interrupt handlers to cover also fast interrupt sources, updated the article
|
||
about the OS porting.
|
||
- Long overdue test code cleanup and documentation.
|
||
- Added new test cases, now the coverage is again up to 100% except for the
|
||
debug module that would require triggering system terminating tests (panics),
|
||
the uncovered code is minimal, extremely simple and working anyway.
|
||
- ChibiOS/RT has been successfully verified with the latest GCC 4.5.0.
|
||
|
||
*** 1.5.5 ***
|
||
- FIX: Removed some "dead" code in the old ARMv7-M files (there are new
|
||
ones, see below).
|
||
- NEW: LPC13xx support, drivers (Serial, PAL, HAL), demo and reports.
|
||
- NEW: Added statistic info to the lwIP demo.
|
||
- CHANGE: Renamed LPC111x port and platform in LPC11xx, minor fixes to the
|
||
platform header files.
|
||
- CHANGE: Small documentation fixes and improvements.
|
||
- OPT: New Cortex-M3 port code, *huge* performance improvements in all the
|
||
context switching related benchmarks (up to 18% depending on the benchmark).
|
||
The new code does no more require the use of the PendSV vector that is
|
||
thus available to the user, it also saves four RAM bytes for each thread
|
||
in the system. The old code is still available as a fall back option while
|
||
the new one is being hardened by peer review and time, the two ports are
|
||
perfectly interchangeable.
|
||
|
||
*** 1.5.4 ***
|
||
- FIX: Fixed broken CH_CURRP_REGISTER_CACHE option in the ARM7 port (bug
|
||
2973365).
|
||
- FIX: Fixed missing memory recovery on thread reference release in
|
||
chRegNextThread() (bug 2971878).
|
||
- FIX: Fixed wrong thread state macro in STM32/spi_lld.c (bug 2968142).
|
||
- NEW: New unified ARM Cortex-Mx port, this port supports both the ARMv6M
|
||
and ARMv7-M architecture (Cortex-M0/M1/M3/M4 so far). The new port also
|
||
allow to easily add to new Cortex-M implementations by simply adding a
|
||
parameters file (cmparams.h).
|
||
- NEW: Embedded Artists LPCxpresso Base Board support files added.
|
||
- NEW: LPC111x support, drivers (Serial, PAL, HAL) and demo.
|
||
- NEW: The port layer now can "capture" the implementation of individual
|
||
scheduler API functions in order to provide architecture-optimized
|
||
versions. This is done because further scheduler optimizations are
|
||
becoming increasingly pointless without considering architecture and
|
||
compiler related constraints.
|
||
- NEW: Added support for the STM8 large memory model to the STM8 port. Now
|
||
the assembler port code is totally inlined and the chcoreasm.asm file has
|
||
been removed.
|
||
- NEW: Added RIDE7 project files to the STM32 demo under a ./ride7
|
||
subdirectory, this should make things easier for RIDE7 users. The normal
|
||
makefile is still available of course.
|
||
- NEW: New articles and guides in the documentation.
|
||
- NEW: Documentation improvements, now the description goes on top of each
|
||
page, doxygen defaulted it in the middle, not exactly the best for
|
||
readability. Improved many descriptions of the various subsystems. Fixed
|
||
a misplaced page (STM8 port).
|
||
- OPT: Optimization on the interface between scheduler and port layer, now
|
||
the kernel is even smaller and the context switch performance improved
|
||
quite a bit on all the supported architectures.
|
||
- OPT: Simplified the implementation of chSchYieldS() and made it a macro.
|
||
The previous implementation was probably overkill and took too much space
|
||
even if a bit faster.
|
||
- CHANGE: Modified the Cortex-M3 port to be a more generic Cortex-Mx port,
|
||
changes were required to the startup code and the port code because the
|
||
reduced instruction set of the Cortex-M0 (there are two code paths now,
|
||
both optimized).
|
||
- CHANGE: Modified the SysTick initialization for STM32 to use the system
|
||
clock rather than the external clock.
|
||
- CHANGE: Exiting from a chCondWaitTimeout() because a timeout now does not
|
||
re-acquire the mutex, ownership is lost.
|
||
- CHANGE: The module documentation has been moved from the kernel.dox file
|
||
to the various source code files in order to make it easier to maintain
|
||
and double as source comments.
|
||
- CHANGE: Updated CMSIS files to version 1.3 and fixed the warnings in there,
|
||
again...
|
||
|
||
*** 1.5.3 ***
|
||
- FIX: Removed C99-style variables declarations (bug 2964418)(backported
|
||
in 1.4.2).
|
||
- FIX: Fixed missing reschedule in chEvtSignal() (bug 2961208)(backported
|
||
in 1.4.2).
|
||
- NEW: Added STM8 port and demo, the demo targets the Raisonance REva board
|
||
with STM8S208RB piggyback.
|
||
- NEW: Enhanced the kernel size report to cover more cases.
|
||
- NEW: Improvements to the documentation.
|
||
- OPT: Minor optimizations in the "compact" code path.
|
||
|
||
*** 1.5.2 ***
|
||
- FIX: Fixed wrong UART deinitialization sequence in LPC214x serial driver
|
||
(bug 2953985)(backported in 1.4.1).
|
||
- FIX: Fixed wrong PINSEL2 offset into lpc214x.h (bug 2953981)(backported
|
||
in 1.4.1).
|
||
- FIX: Fixed invalid UART-related macro in the LPC214x HAL (bug 2953195)
|
||
(backported in 1.4.1).
|
||
- FIX: Impossible to enforce alignment greater of a pointer size for heap/core
|
||
objects (bug 2952961).
|
||
- FIX: Wrong prototype in template file chcore.c (bug 2951529)(backported
|
||
in 1.4.1).
|
||
- NEW: Added an experimental PowerPC port targeting the SPC563M/MPC563xM
|
||
ST/Freescale automotive SOCs. The port passed the whole test suite but it
|
||
will be developed further in next releases.
|
||
- NEW: Added core variant name macro in chcore.h and platform name in
|
||
hal_lld.h, the info are printed in the test report and from the "info"
|
||
shell command.
|
||
- NEW: Added BOARD_NAME macro to the various board.h files.
|
||
- NEW: Added a MemoryStream class under ./os/various.
|
||
- CHANGE: Removed an instance of a structure without name from test.h for
|
||
increased portability of the test suite.
|
||
- NEW: Added Mac OS-X support for the simulator. The Linux simulator has
|
||
been renamed to Posix simulator in order to include this change in a
|
||
single project.
|
||
- NEW: New articles, sections and various improvements to the documentation.
|
||
- CHANGE: Renamed the kernel header files to match the names of their source
|
||
files. The change was also required in order to make the names less
|
||
"generic" and less likely to match names in external libraries.
|
||
|
||
*** 1.5.1 ***
|
||
- FIX: Fixed insufficient stack space for the idle thread in the ARMCM3 port
|
||
when compiling without optimizations (bug 2946233)(backported in 1.4.1).
|
||
- FIX: Fixed wrong notes on function chThdResume() (bug 2943160)(backported
|
||
in 1.4.1).
|
||
- NEW: Implemented the concept of thread references, this mechanism ensures
|
||
that a dynamic thread's memory is not freed while some other thread still
|
||
owns a reference to the thread. Static threads are not affected by the new
|
||
mechanism. Two new APIs have been added: chThdAddRef() and chThdRelease().
|
||
- NEW: Now more than one thread can be waiting in chThdWait() as long they
|
||
own a reference.
|
||
- NEW: Implemented a new threads registry subsystem, the registry allows to
|
||
enumerate the active threads at runtime and/or from a debugger. This is
|
||
a preparatory step for a dedicated ChibiOS/RT debugger.
|
||
- NEW: New chCoreFree() API that returns the core memory left.
|
||
- NEW: Added to the simulators shell demos two new commands: threads and mem,
|
||
that show the currently active threads (using the new registry) and the
|
||
memory allocators state.
|
||
- CHANGE: Doxygen tags cleanup in all the system code, comments are better
|
||
looking now.
|
||
- CHANGE: Documentation improvements.
|
||
|
||
*** 1.5.0 ***
|
||
- FIX: Fixed missing dependencies check for CH_USE_DYNAMIC (bug 2942757)
|
||
(backported in 1.4.1).
|
||
- FIX: Fixed swapped thread states descriptions (bug 2938445)(backported in
|
||
1.4.1).
|
||
- FIX_ Fixed C99-style variable declaration (bug 2938444)(backported in 1.4.1).
|
||
- FIX: Fixed parameter check in sdStart() function (bug 2932922)(backported in
|
||
1.4.0).
|
||
- FIX: Fixed missing platform.mk file in MSP430 port (bug 2933735)(backported
|
||
in 1.4.0).
|
||
- CHANGE: Removed the unnamed union from the thread and heaps structures,
|
||
some compilers do not support this non standard construct.
|
||
- CHANGE: Removed the empty structures from the streams/channels headers.
|
||
- CHANGE: Modified the thread-related constant macros to have a THD_ prefix.
|
||
- CHANGE: Modified NULL assignments to function pointers to use an explicit
|
||
cast because some compilers issue warnings without the cast.
|
||
- OPT: Speed/size optimization to the events subsystem.
|
||
- OPT: Speed/size optimization to the mutexes subsystem.
|
||
- OPT: Speed/size optimization to the condvars subsystem.
|
||
- OPT: Speed/size optimization to the synchronous messages subsystem.
|
||
- NEW: Added support for STM32/HD/CL UART4 and UART5, thanks Egon for the
|
||
patch.
|
||
|
||
*** 1.3.8 ***
|
||
- FIX: Fixed dequeuing in lifo_remove() function (bug 2928142).
|
||
- FIX: Fixed spurious character generation in MSP430 serial driver (bug
|
||
2926838).
|
||
- NEW: Introduced an abstract streams interface BaseSequentialStream.
|
||
- NEW: Added timeout specification to the I/O queues read/write primitives.
|
||
- NEW: Added support for HD and CL STM32 devices in the vectors table.
|
||
- CHANGE: Modified the BaseChannel interface in order to make it a
|
||
BaseSequentialStream descendant.
|
||
- CHANGE: Updated the serial driver model in order to expose the
|
||
BaseSequentialStream methods.
|
||
- CHANGE: The behavior of the read/write primitives is changed, now the
|
||
functions are synchronous and do not return until the specified number of
|
||
bytes have been transferred or a timeout occurs, the old behavior can be
|
||
replicated by specifying TIME_IMMEDIATE as timeout. Another difference is
|
||
that specifying zero as bytes number is like specifying the largest size_t
|
||
plus one, zero was an illegal value before.
|
||
- CHANGE: Simplified the LPC214x driver by removing the option to not use the
|
||
FIFO preload feature. Setting LPC214x_UART_FIFO_PRELOAD to 1 results in
|
||
the same behavior.
|
||
- Documentation fixes and improvements, testing strategy explained.
|
||
- Added article about waking up threads from IRQ handlers.
|
||
|
||
*** 1.3.7 ***
|
||
- FIX: Fixed duplicated definition of SPI_USE_MUTUAL_EXCLUSION (bug 2922495).
|
||
- FIX: Fixed coverage tool hanging during execution (bug 2921120).
|
||
- FIX: Fixed Linux simulator startup message (bug 2921012).
|
||
- FIX: Fixed section separators comments into the HAL-related files. Now all
|
||
the files should use the same style.
|
||
- NEW: Improved HAL configuration file.
|
||
- NEW: Introduced a new, per-project, MCU configuration file mcuconf.h that
|
||
contains all the drivers related settings.
|
||
- NEW: Readability improvements to the channels code.
|
||
- NEW: Serial driver model improvements, added states management and checks,
|
||
added a new SD_NOISE_ERROR error event.
|
||
- NEW: Improvements and optimizations in the various serial driver
|
||
implementations.
|
||
- Documentation fixes and improvements.
|
||
|
||
*** 1.3.6 ***
|
||
- FIX: Fixed missing STM32 PWM low level driver error in platform.mk by
|
||
adding the driver files (bug 2913560).
|
||
- NEW: The Linux simulator now works again, also supports the serial
|
||
drivers over TCP/IP and has a command line interface like the Win32
|
||
simulator.
|
||
- NEW: STM32 PWM driver implementation.
|
||
- NEW: LPC214x SPI driver implementation (SSP only, polled mode, no IRQ), this
|
||
driver replaces the old, not HAL compatible, SSP driver.
|
||
- NEW: LPC214x FatFS demo added, LPC214x minimal demo removed, LPC214x "normal"
|
||
demo reduced to work like all the other generic demos.
|
||
- NEW: Added custom mode settings to the STM32 PAL driver:
|
||
- PAL_MODE_STM32_ALTERNATE_PUSHPULL
|
||
- PAL_MODE_STM32_ALTERNATE_OPENDRAIN
|
||
- NEW: Included all the board-specific files into a new directories structure
|
||
under ./boards, this allows to not duplicate the board files into each demo.
|
||
- CHANGE: Changes to the PWM driver model, made it simpler.
|
||
- CHANGE: The STM32 device drivers now no more configure the I/O pins on
|
||
initialization. Pins must be configured in board.h, the change was required
|
||
in order to support the STM32 AFIO remapping feature.
|
||
- CHANGE: Removed the mmcsd.c driver, it is replaced by the generic MMC_SPI
|
||
driver present into the HAL.
|
||
- CHANGE: Updated the GPL exception text in the documentation, this should be
|
||
the final text for the stable version 1.4.x.
|
||
|
||
*** 1.3.5 ***
|
||
- FIX: Fixed problem with memory core allocator (bug 2912528).
|
||
- FIX: Fixed problem with CH_USE_MEMCORE option (bug 2912522).
|
||
- FIX: Fixed some problems in the MMC_SPI driver (bugs 2901084 and 2901172).
|
||
- NEW: Added a command line shell component, modified the Win32 simulator
|
||
in order to use the new shell. The shell can be used under any architecture,
|
||
it just requires an I/O channel. Custom commands can be easily added.
|
||
- NEW: Unified the initialization of the various drivers from a single HAL
|
||
driver. The single drivers can be enabled or disabled from a HAL
|
||
configuration file halconf.h.
|
||
- NEW: New CAN driver model.
|
||
- NEW: New PWM driver model.
|
||
- NEW: STM32 ADC driver implementation with DMA support.
|
||
- NEW: STM32 CAN driver implementation.
|
||
- NEW: Extended the support to all the SAM7X and SAM7S devices thanks to
|
||
code contributed by Liam Staskawicz.
|
||
- NEW: Improvements to the AT91SAM7 startup code contributed by Liam.
|
||
- NEW: Added test report for MSP430 running from the external high speed
|
||
oscillator.
|
||
- NEW: HAL stress test for STM32 added, the demo is located under
|
||
./testhal/STM32. The demo code also shows how to use the ADC, CAN and SPI
|
||
drivers.
|
||
- CHANGE: Removed the MII from the standard drivers, now it is part of the
|
||
AT91SAM7 support, the header mii.h is still part of the HAL.
|
||
- CHANGE: In the STM32 drivers now the DMA errors are handled by hook macros
|
||
rather than by events. The default action is to halt the system but users
|
||
are able to override this and define custom handling.
|
||
- CHANGE: In the Cortex-M3 port, modified the NVICEnableVector() function
|
||
to make it clear pending interrupts.
|
||
- CHANGE: Minor changes to the ADC driver model.
|
||
|
||
*** 1.3.4 ***
|
||
- FIX: Fixed bug in STM32 PAL port driver (bug 2897636).
|
||
- FIX: Fixed problem with ARM-CM3 context switch when compiled at level
|
||
-O0 (bug 2890382).
|
||
- FIX: Fixed wrong conditional in chschd.c (bug 2888836).
|
||
- FIX: Fixed wrong macro in chheap.c (bug 2888833).
|
||
- FIX: Fixed AIC initialization in AT91SAM7X support (bug 2888583).
|
||
- NEW: New SPI (master) driver model.
|
||
- NEW: SPI driver for STM32 implementing the new SPI driver model.
|
||
- NEW: New ADC (streaming capable) driver model.
|
||
- NEW: Generic MMC (over SPI) driver.
|
||
- NEW: Added a STM32 demo that integrates the MMC driver and the FatFs
|
||
file system.
|
||
- NEW: Implemented I/O redirection on a serial driver into syscalls.c, now
|
||
it is possible (but not recommended) to use printf()/scanf() etc. An usage
|
||
example is in the new MMC/FatFs demo. Note the extra -D... into the Makefile.
|
||
- CHANGE: Moved the STM32 firmware library under ./ext, this way there is no
|
||
need to duplicate it in each demo program.
|
||
- CHANGE: Moved the file stm32f10x.h from the demos to the platforms support
|
||
directory.
|
||
|
||
*** 1.3.3 ***
|
||
- FIX: Fixed bug in the LPC2148 PAL driver (bug 2881380).
|
||
- FIX: Fixed bug in the AT91SAM7X PAL driver (bug 2879933).
|
||
- NEW: New MAC and MII driver models and implementations for the AT91SAM7X.
|
||
Removed the old EMAC driver, updated the uIP WEB demo to use the new
|
||
driver model.
|
||
- NEW: Added a simple lwIP demo (web server) for the AT91SAM7X.
|
||
- NEW: Centralized core memory manager. This simple allocator implements a
|
||
sbrk()-like API: chCoreAlloc(). The other allocators now use this manager
|
||
in order to get memory blocks.
|
||
- NEW: The heap allocator has been modified, now it is possible to have
|
||
multiple heaps. The default heap gets its memory from the new core memory
|
||
manager.
|
||
- NEW: Now memory pools can optionally get new objects automatically from the
|
||
core memory manager.
|
||
- NEW: Added newlib interface file syscalls.c under ./os/various for use with
|
||
the newest YAGARTO releases. The file provides bindings between the C
|
||
runtime and the core memory manager.
|
||
- CHANGE: Because the changes in the allocators some API prototypes changed:
|
||
chHeapAlloc(), chHeapStatus(), chThdCreateFromHeap().
|
||
- CHANGE: Because the changes in the allocators some configuration options
|
||
changed and some were removed, see the new template chconf.h file.
|
||
- CHANGE: renamed ./demos/ARM7-AT91SAM7X-WEB-GCC in ARM7-AT91SAM7X-UIP-GCC.
|
||
- FIX: Added the most restrictive GCC warning option to the makefiles (-Wextra)
|
||
and fixed some warnings in the code, mostly unused function parameters.
|
||
|
||
*** 1.3.2 ***
|
||
- FIX: Fixed GCC 4.4.x aliasing warnings (bug 2846336)(backported in stable
|
||
branch).
|
||
- FIX: Modified linker scripts for GCC 4.4.x (bug 2846302)(backported in stable
|
||
branch).
|
||
- FIX: Fixed the CH_OPTIMIZE_SPEED option in the CM3 port (bug 2846278)
|
||
(backported in stable branch).
|
||
- FIX: Fixed GCC 4.4.x related problems in CM3 port (bug 2846162)(backported
|
||
in stable branch).
|
||
- FIX: Fixed LPC214x UART problem (bug 2841088)(backported in stable branch).
|
||
- NEW: Improved the Cortex-M3 preemption code, now less interrupt-related
|
||
jitter is generated and all benchmarks scores improved a bit.
|
||
- NEW: Added new APIs chSchDoYieldS() and chThdYield().
|
||
- MEW: Added new benchmark about RAM footprint.
|
||
- MEW: Added new benchmark about round robin rescheduling.
|
||
- NEW: Reorganized and rationalized the distribution tree and the
|
||
documentation.
|
||
- NEW: Enhanced serial driver. The driver now supports speed change at runtime
|
||
and low power stop mode.
|
||
- NEW: Serial driver removed from the kernel and added to the I/O subsystems
|
||
together with PAL. Note that the related API names changed their prefix from
|
||
chFDDxxx to sdxxx because of this.
|
||
- NEW: Added standard CMSIS 1.2.0 support to the Cortex-M3 port. The kernel
|
||
does not use it (the OS uses its own optimized code) but the functionality
|
||
is available to the applications. The CMSIS files were patched in order
|
||
to correct some warnings.
|
||
- NEW: Updated the STM32 port to use the newest ST firmware library files
|
||
(version 3.1.0). Note that now the ST drivers are included in the STM32
|
||
demo directory.
|
||
- NEW: Improved makefiles and makefile fragments, now the paths are not fixed,
|
||
the fragments can be included also from projects outside the ChibiOS/RT files
|
||
structure by simply defining the variable ${CHIBIOS}.
|
||
- CHANGE: Removed the CH_USE_SERIAL_FULLDUPLEX configuration option because
|
||
the serial driver is no more part of the kernel.
|
||
- CHANGE: Reorganized the PAL and Serial identifiers now IOPORT1..N and
|
||
SD1..N rather than IOPORT_A..Z and COM1..N, some of the old names were
|
||
conflicting with some AVR libraries.
|
||
|
||
*** 1.3.1 ***
|
||
- FIX: Removed mention of an obsolete option from the documentation (bug
|
||
2799507).
|
||
- NEW: Abstract digital I/O ports driver (PAL), this driver defines a common
|
||
interface for digital I/O operations, this should help to create more
|
||
portable applications and, in general, make easier to work with ChibiOS/RT
|
||
on multiple architectures.
|
||
- NEW: Port drivers for STM32, LPC214x, AT91SAM7X and MSP430, cleaned up the
|
||
initialization code in board.c. All the demos now use PAL for I/O. AVR is
|
||
not supported because its "sparse" registers layout, it would not be
|
||
efficient enough for my taste.
|
||
- Modified the STM32 demo to use the bit definitions in the ST header file,
|
||
removed the bit definitions in board.h and stm32_serial.h.
|
||
- Documentation section reorganization and fixes.
|
||
- Changed the STM32 demo stack sizes, it was incorrectly adjusted in version
|
||
1.3.0 but it did not create problems (not a bug).
|
||
|
||
*** 1.3.0 ***
|
||
- FIX: Fixed regression in MinGW demo (bug 2745153)(backported in stable
|
||
branch).
|
||
- FIX: Fixed problem with the timeout constant TIME_IMMEDIATE, added a
|
||
specific test in the test suite (bug 2755170)(backported in stable branch).
|
||
- FIX: Fixed a problem in semaphores test case #2 (bug 2755195)(backported
|
||
in stable branch).
|
||
- FIX: Removed unused list functions (bug 2755230)(backported in stable
|
||
branch).
|
||
- FIX: Added license notice to several files (bug 2772160)(backported in
|
||
stable branch).
|
||
- FIX: Found new instances of the obsolete function chSysGetTime() in the
|
||
C++ wrapper and in the WEB demo (bug 2772237)(backported in stable branch).
|
||
- FIX: Fixed macro in test.h (bug 2781176)(backported in stable branch).
|
||
- FIX: Fixed sequence assertion in test.c (bug 2789377)(backported in stable
|
||
branch).
|
||
- FIX: Fixed test_cpu_pulse() incorrect behavior (bug 2789383)(backported in
|
||
stable branch).
|
||
- FIX: Fixed missing volatile modifier for p_time field in Thread structure
|
||
(bug 2789501)(backported in stable branch).
|
||
- FIX: Fixed C99-style variable declarations (bug 2792919)(backported in
|
||
stable branch).
|
||
- FIX: Fixed instance of obsolete CH_USE_TERMINATE option in the C++ wrapper
|
||
(bug 2796065)(backported in stable branch).
|
||
- FIX: Insufficient stack allocated to the C++ LPC2148 demo (bug 2796069)
|
||
(backported in stable branch).
|
||
- FIX: Fixed errors in events test case (bug 2796081)(backported in stable
|
||
branch).
|
||
- NEW: Abstract I/O Channels mechanism introduced. This mechanism allows to
|
||
access I/O resources through a standard interface and hides implementation
|
||
details. The existing serial drivers were modified to offer a standard
|
||
channel interface to the applications (the old APIs are retained as macros).
|
||
- NEW: The I/O queues code was improved, now there are 2 separate structures:
|
||
InputQueue and OutputQueue. There are some changes in the queue APIs
|
||
in order to make them more symmetrical and functional. Improved the queues
|
||
documentation. Some of the changes were needed in order to support the new
|
||
channels mechanism as a backend for queued serial drivers.
|
||
- NEW: Static initializers macros introduced for most kernel objects. The
|
||
static initializers allow to not have to chXXXInit() any object and save some
|
||
code space. The initialization functions are retained in order to allow
|
||
initialization of dynamic objects and re-initializations.
|
||
- NEW: Added more test cases in order to improve the test suite code coverage
|
||
(it was 74% in version 1.2.0, it is now close to 100%).
|
||
- NEW: Added test cases for the improved queues and serial drivers.
|
||
- NEW: Added a code coverage analysis application under ./tests/coverage.
|
||
- NEW: Added the test suite documentation to the general documentation.
|
||
- NEW: Added a new "naked" context switch benchmark that better defines the
|
||
real context switch time, previous benchmarks introduced too much overhead
|
||
to the measurement. The STM32 performs the context switch in under 1.48uS.
|
||
- NEW: Improved priority inheritance test cases.
|
||
- NEW: Added architecture name strings to the port code.
|
||
- NEW: Linux x86 simulator demo added. It is still work in progress.
|
||
- CHANGE: Removed the half duplex queues and half duplex serial drivers because
|
||
it was never extensively tested. The code is still available but not as part
|
||
of the kernel.
|
||
- CHANGE: Removed the chMsgSendWithEvent() function. It is rarely used and
|
||
the functionality can be re-created with a compound atomic operation. Also
|
||
removed the CH_USE_MESSAGES_EVENT configuration option.
|
||
- CHANGE: Modified the test suite assertions in order to save RAM on the AVR
|
||
targets. The test suite now uses much less string space.
|
||
- CHANGE: Removed the CH_USE_SERIAL_HALFDUPLEX, CH_USE_QUEUES_TIMEOUT,
|
||
CH_USE_QUEUES_HALFDUPLEX, CH_USE_SEMAPHORES_TIMEOUT configuration options.
|
||
- CHANGE: Made CH_DBG_THREADS_PROFILING default to TRUE in all demos because
|
||
the changes to the function test_cpu_pulse().
|
||
- CHANGE: Increased main stack size to 1KiB for all the ARMx demos, 2KiB for
|
||
the C++ LPC2148 demo. This should make things easier for unexperienced
|
||
users.
|
||
|
||
*** 1.2.0 ***
|
||
- Added license exception text to the 1.2.0 branch.
|
||
- FIX: Fixed serious AVR regression (bug 2731578).
|
||
- FIX: Fixed build failure when CH_USE_MUTEXES=FALSE (bug 2730706).
|
||
- FIX: Removed reference to an obsolete function (bug 2731661).
|
||
- Full test cycle and test reports updated.
|
||
- Small fixes to the documentation.
|
||
|
||
*** 1.1.3unstable ***
|
||
- FIX: Fixed makefile in STM32 demo, this bug was reported fixed in
|
||
version 1.1.2 but it was still there (bug 2686451).
|
||
- FIX: Fixed makefile in MSP430 demo (bug 2700690).
|
||
- FIX: Fixed thumb mode build error in AT91SAM7X demos (bug 2700695).
|
||
|
||
*** 1.1.2unstable ***
|
||
- FIX: Fixed priority inheritance problem with condvars (bug 2674756) and
|
||
added a specific test case to the test suite (backported in stable branch).
|
||
- FIX: Fixed a problem in time ranges (bug 2680425)(backported in stable
|
||
branch).
|
||
- FIX: Build error with option CH_DBG_FILL_THREADS (bug 2683965).
|
||
- FIX: Fixed a wrong parameter check in chVTSetI() and chThdSleep()
|
||
(bug 2679155).
|
||
- FIX: Build error with options CH_USE_NESTED_LOCKS && !CH_OPTIMIZE_SPEED
|
||
(bug 2678928).
|
||
- FIX: Removed unused chSysPuts() macro (bug 2672678).
|
||
- FIX: Renamed function chSysInTimeWindow() as chTimeIsWithin() and renamed
|
||
the macro chSysGetTime() in chTimeNow(), the old names are still recognized
|
||
but marked as deprecated (fixes the bug 2678953 but goes a bit further by
|
||
introducing a new API category "Time").
|
||
- FIX: Fixed makefile problems in the AT91SAM7X256 and STM32 demos (bugs
|
||
2686347 and 2686451).
|
||
- FIX: Fixed AT91SAM7X256 EMAC driver (bug 2686349).
|
||
- FIX: Fixed small some errors in the documentation (bug 2692510).
|
||
- OPT: Small optimization to the Cortex-M3 thread startup code, improved thread
|
||
related performance scores and smaller code.
|
||
- OPT: Alternative, non-inlined and more compact, implementations for
|
||
port_lock() and port_unlock() in the Cortex-M3 port when CH_OPTIMIZE_SPEED
|
||
is FALSE.
|
||
- OPT: Improved ready list and priority ordered lists code, some space saved,
|
||
better context switch performance.
|
||
- Modified the test thread function to return the global test result flag.
|
||
- Removed testcond.c|h and moved the test cases into testmtx.c. Mutexes and
|
||
condvars have to be tested together.
|
||
- Added architecture diagram to the documentation.
|
||
- Removed from the documentation some references to long gone functions...
|
||
|
||
*** 1.1.1unstable ***
|
||
- FIX: Fixed a problem into the STACK_ALIGN() macro (backported in stable
|
||
branch).
|
||
- FIX: Fixed a problem with a wrong declaration of the PLL structure in the
|
||
file lpc214x.h (backported in stable branch).
|
||
- FIX: Fixed build problem with the C++ demo (bug 2687489).
|
||
- FIX: Removed EMAC driver from the AT91SAM7X256 demo makefile (bug 2686347).
|
||
- FIX: Removed C++ wrapper from the STM32 demo makefile (bug 2686451).
|
||
- FIX: Fixed a problem with some event APIs not showing in the documentation
|
||
(backported in stable branch).
|
||
- FIX: Fixed wrong assertions in chThdWait() and chHeapFree() (backported in
|
||
stable branch).
|
||
- FIX: Fixed @file tag in sam7x_serial.c (bug 2788573) (backported in stable
|
||
branch).
|
||
- FIX: Fixed a small problem in the chcore.c template file.
|
||
- NEW: Mailboxes (asynchronous messages) subsystem and test cases added.
|
||
- NEW: Most APIs with a timeout specification now accept the constant
|
||
TIME_IMMEDIATE (-1) that triggers an immediate timeout when trying to enter
|
||
a sleep state.
|
||
- NEW: Mode flexible debug configuration options, removed the old CH_USE_DEBUG
|
||
and CH_USE_TRACE. Replaced with CH_DBG_ENABLE_CHECKS, SCH_DBG_ENABLE_ASSERTS,
|
||
CH_DBG_ENABLE_TRACE and CH_DBG_FILL_THREADS.
|
||
- NEW: Added a debug option CH_DBG_THREADS_PROFILING for threads profiling.
|
||
A field into the Thread structure counts the consumed time. The information
|
||
is not used into the kernel, it is meant for debugging.
|
||
- NEW: Added a debug option CH_DBG_ENABLE_STACK_CHECK for stack overflow
|
||
checking. The check is not performed in the kernel but in the port code.
|
||
Currently only the ARM7 and ARMCM3 ports implements it.
|
||
- NEW: Unified makefiles for ARM7, ARMCM3 MSP430 projects, the new makefiles
|
||
share a common part making them easier to maintain. Also reorganized the
|
||
demo-specific part of the makefile, now it is easier to configure and the
|
||
option can be overridden from outside.
|
||
- CHANGE: Changed the chSemFastWaitS() macro in chSemFastWaitI() and
|
||
chSemGetCounter() in chSemGetCounterI().
|
||
- CHANGE: Removed the port_puts() function from the port templates. It was not
|
||
implemented on all ports.
|
||
- Improvements to the test suite, added a new level of indirection that allows
|
||
to make tests depend on the configuration options without have to put #ifs
|
||
into the test main module. New benchmarks about semaphores and mutexes.
|
||
|
||
*** 1.1.0unstable ***
|
||
- FIX: Modified the default value for the STM32 HSI setup it was 1, it should
|
||
be 0x10 (backported in stable branch).
|
||
- FIX: Removed an obsolete constant (P_SUSPENDED) from thread.h (backported in
|
||
stable branch).
|
||
- FIX: Removed unused field mp_grow in the MemoryPool structure (backported in
|
||
stable branch).
|
||
- NEW: Added to the STM32 demo makefile an option to build ChibiOS/RT with the
|
||
full STM32 FWLib 2.03. **NOTE**, except for the makefile option, the
|
||
library is not used by the OS nor required (backported in stable branch).
|
||
- NEW: Better separation between the port code and the system APIs, now an
|
||
architecture-specific "driver" contains all the port related code.
|
||
Port functions/macros are no more directly exposed as APIs to the user code.
|
||
- NEW: Added a configuration option to enable nested system locks/unlocks.
|
||
- NEW: Improved the interrupt handlers related code. Now interrupts are
|
||
handled in a very similar way in every architecture. See the "Concepts"
|
||
section and the "Writing interrupt handlers under ChibiOS/RT" article in the
|
||
documentation.
|
||
- NEW: Added the chEvtSignal() and chEvtSignalI() APIs that allows direct
|
||
thread signaling, much more efficient that chEvtBroadcast() when the target
|
||
is a known single thread.
|
||
- NEW: Added a configuration option that enables the priority enqueuing on
|
||
semaphores. It is defaulted to off because usually semaphores are used for
|
||
I/O related tasks without hard realtime requirements.
|
||
- NEW: Now the all the options in chconf.h and the various driver headers
|
||
can be overridden externally, for example from within the Makefile.
|
||
The options are no mode a simple define but a define with an assigned
|
||
TRUE/FALSE value within an #ifndef block.
|
||
- NEW: Idle thread hook macro added to the configuration file.
|
||
- NEW: Changed the ARM7 and Cortex-M3 startup files, now the action when
|
||
the main() function returns can be overridden by redefining the symbol
|
||
MainExitHandler.
|
||
- OPT: Improved ARM7 thumb port code, thanks to some GCC tricks involving
|
||
registers usage now the kernel is much smaller, faster and most OS APIs
|
||
use less RAM in stack frames (note, this is an ARM7 thumb mode specific
|
||
optimization).
|
||
- CHANGE: Now the API chThdSetPriority() returns the old priority instead
|
||
of void.
|
||
- CHANGE: Modified the signature of the chMsgSendWithEvent() API, it now uses
|
||
a more efficient event signaling method.
|
||
- CHANGE: Removed the field p_tid from the Thread structure and the related
|
||
code, this improved the thread creation scores (~2%) and saves some RAM.
|
||
The trace buffer field cse_tid is now populated with a simple hash of the
|
||
thread pointer as thread identifier.
|
||
- CHANGE: Renamed the macros chSysIRQEnter() and chSysIRQExit() in
|
||
CH_IRQ_PROLOGUE() and CH_IRQ_EPILOGUE() in order to make very clear that
|
||
those are not functions but inlined code. Also introduced a new macro
|
||
CH_IRQ_HANDLER that should be used when declaring an interrupt handler.
|
||
- CHANGE: Renamed several internal initialization functions by removing the
|
||
"ch" prefix because could not be considered system APIs.
|
||
- Improved ARM7 and Cortex-M3 support, new configuration options.
|
||
- Introduced the concept of interrupt classes, see the documentation.
|
||
- Introduced the concept of system states, see the documentation.
|
||
- Huge improvements to the documentation.
|
||
- Articles and notes previously in the wiki now merged in the general
|
||
documentation and updated, the wiki entries are obsolete and will be removed.
|
||
- New application notes and articles added.
|
||
- Added kernel size metrics to the test reports.
|
||
- Removed the inclusion graph from the documentation because the little
|
||
info they add and the size of all the images. It is possible to configure
|
||
Doxygen to have them again (and more graph types).
|
||
|
||
*** 1.0.0 ***
|
||
- License switch, added GPL exception, see exception.txt.
|
||
- Full test cycle and test reports updated.
|
||
- Renamed some occurrences of "Conditional Variable" in "Condition Variable" in
|
||
the documentation.
|
||
- FIX: Fixed some images in the documentation because problems when seen in
|
||
Internet Explorer.
|
||
|
||
*** 1.0.0rc3 ***
|
||
- FIX: Fixed a nasty regression to the timeout unified code that affected
|
||
some APIs since version 0.5.3. See the bug tracker for more details.
|
||
Added a test case about this.
|
||
- FIX: Removed the API chThdSuspend() there was a conceptual flaw and I want
|
||
to think about the whole concept again before introducing something similar
|
||
in future. Anyway, it is possible to replicate the functionality using
|
||
chSchGoSleepS().
|
||
- Fixed typos here and there.
|
||
- Updated the states diagram in the documentation.
|
||
|
||
*** 1.0.0rc2 ***
|
||
- FIX: Removed unused variable "retaddr" from the Cortex-M3 port.
|
||
- FIX: The macro THD_WA_SIZE was defined wrongly in the file
|
||
./src/templates/chcore.h.
|
||
- Fixed some errors in the documentation.
|
||
|
||
*** 1.0.0rc1 ***
|
||
- NEW: Added new macros CH_KERNEL_VERSION set to "1.0.0rc1", CH_KERNEL_MAJOR
|
||
set to 1, CH_KERNEL_MINOR set to 0, CH_KERNEL_PATCH set to 0.
|
||
The macros will be updated to reflect the actual kernel version number.
|
||
- NEW: Made all the port-specific configuration settings externally
|
||
configurable, see the documentation.
|
||
- FIX: Disabled the configuration option CH_USE_MESSAGES_PRIORITY from the
|
||
MSP430 demo, the default for this option should be off.
|
||
- FIX: Fixed a bug that prevented the THREAD_EXT_FIELDS to be compiled into
|
||
the Thread structure.
|
||
- FIX: Removed some references to deprecated APIs from the test suite.
|
||
- FIX: Set the INT_REQUIRED_STACK configuration value for the ARM7 port to a
|
||
safer 0x10, it was previously 0 (correct but trimmed to specific compiler
|
||
settings).
|
||
- FIX: Set the INT_REQUIRED_STACK configuration value for the AVR port to a
|
||
safer 32.
|
||
- FIX: Fixed the MinGW demo in order to not use any deprecated construct.
|
||
- Removed deprecated threads APIs: chThdCreate() and chThdCreateFast().
|
||
- Removed deprecated events APIs: chEvtWait(), chEvtWaitTimeout(), chEvtSend(),
|
||
chEvtSendI(), EventMask().
|
||
- Removed deprecated configuration feature CH_USE_EXIT_EVENT and the related
|
||
API chThdGetExitEventSource(). The feature can be reimplemented in user code
|
||
as shown by the MinGW demo.
|
||
- Removed deprecated macros: WorkingArea(), UserStackSize(), StackAlign().
|
||
- Added usage note into the readme of the MinGW demo.
|
||
- Added usage notes for programmers to the ARM7 port documentation about
|
||
interrupt handlers.
|
||
- Port-specific settings added to the documentation.
|
||
- Added source browser to the documentation.
|
||
- Fixes and improvements through the documentation.
|
||
|
||
*** 0.8.3 ***
|
||
- NEW: Introduced new API chThdSleepS() as a macro, no real changes in the
|
||
kernel code.
|
||
- FIX: The MinGW simulated demo now works again after breaking in 0.8.2
|
||
because the changes to the macro names.
|
||
- FIX: Adjusted the test suite stack sizes for the MinGW simulated demo, now
|
||
the demo passes all the tests.
|
||
- FIX: Added fflush(stdout) to the MinGW simulation code output in order to
|
||
make the Eclipse console work correctly.
|
||
- FIX: Renamed the MinGW demo main source from demo.c to main.c in order to
|
||
follow the pattern of all the other demos.
|
||
- FIX: Added debug switches to the MinGW simulated demo, not it is possible to
|
||
debug the demo (and the kernel) inside Eclipse without a physical board.
|
||
- Removed lots of old deprecated constructs from the MinGW simulated demo.
|
||
There are still some, the demo will need some rework before version 1.0.0.
|
||
- Updated the C++ wrapper with the latest APIs changes and fixed some bugs.
|
||
- Small fixes to the documentation.
|
||
|
||
*** 0.8.2 ***
|
||
- FIX: Included the files that were missing from version 0.8.1 distribution.
|
||
- FIX: Duplicated sections in the documentation removed.
|
||
- FIX: Minor problem in Cortex-M3 and AVR ports when the kernel is compiled
|
||
using G++.
|
||
- NEW: Added chPoolAllocI() and chPoolFreeI() APIs in order to allow the use
|
||
of memory pools from interrupt handlers and timer callbacks.
|
||
- CHANGE: Simplified the code for chThdWait(), it is now both smaller and
|
||
faster. Added an important usage note to the documentation of this API.
|
||
- CHANGE: The macros WorkingArea(), UserStackSize() and StackAlign() are now
|
||
deprecated and will be removed in version 1.0.0. Use the new equivalents
|
||
WORKING_AREA(), THD_WA_SIZE() and STACK_ALIGN() instead.
|
||
- CHANGE: Renamed the default idle thread function from _IdleThread() to
|
||
_idle().
|
||
- Added to the LPC2148 and STM32 load scripts the options "ALIGN(16)
|
||
SUBALIGN(16)" to the flash loading section in order to enforce the alignment
|
||
for both the code and read only data. This is done in order to obtain more
|
||
accurate timings from benchmarks, those families have 16 bytes
|
||
prefetch buffers and are very sensitive to alignment changes.
|
||
You can remove those options in order to save some flash space if accurate
|
||
response time is not on top of your priorities, it mainly depends on your
|
||
requirements.
|
||
|
||
*** 0.8.1 ***
|
||
- FIX: Fixed a regression in version 0.8.0, the configuration switch
|
||
CH_USE_EVENTS_TIMEOUT was redefined as CH_USE_EVENT_TIMEOUT and this broke
|
||
the code using events timeouts (the LPC2148 C++ demo).
|
||
|
||
*** 0.8.0 ***
|
||
- NEW: Added condvars mechanism on top of the mutexes subsystem.
|
||
- NEW: Improved events subsystems, now it is also possible to use it just as
|
||
"event flags" without have to use event handler callbacks.
|
||
Some new APIs were introduced:
|
||
* chEvtWaitOne() - Wait for a single event.
|
||
* chEvtWaitAny() - Wait with OR condition.
|
||
* chEvtWaitAll() - Wait with AND condition.
|
||
* chEvtDispatch() - Invokes the event handlers associated to a mask.
|
||
* chEvtPend() - Quickly self-pends some events.
|
||
* chEvtRegisterMask() - Registers a set of flags on a single source.
|
||
* EVENT_MASK() - Replaces the old EventMask() macro.
|
||
All the "wait"-type APIs have a timeout-capable variant.
|
||
- CHANGE: The old EventMask(), chEvtWait() and chEvtWaitTimeout() APIs are
|
||
now deprecated and will be removed in version 1.0.0.
|
||
- CHANGE: Modified chDbgAssert() to syntax check the condition even when the
|
||
CH_USE_DEBUG is disabled, it produces no code but allows to check the
|
||
optional code without have to compile twice.
|
||
- FIX: Fixed a warning generated by the chEvtIsListening() macro.
|
||
- Added new test cases to the test suite about condvars and the new events
|
||
APIs.
|
||
- Added a new benchmark to the test suite (timers set/reset performance).
|
||
- Renamed the macro fifo_init() to queue_init() because it is used to init
|
||
both FIFO queues and priority queues.
|
||
- Fixes and improvements to the documentation.
|
||
- Cleaned demo applications of old events code.
|
||
|
||
*** 0.7.3 ***
|
||
- FIX: Fixed a bug in chThdSleepUntil(), this API is no more a macro now.
|
||
- NEW: New chThdSleepSeconds(), chThdSleepMilliseconds() and
|
||
chThdSleepMicroseconds() utility macros.
|
||
- CHANGE: Zero is no more a valid time specification for the chVTSetI() API.
|
||
- CHANGE: Removed the files chsleep.c and sleep.h.
|
||
- CHANGE: Renamed the files chdelta.c and delta.h to chvt.c and vt.h. All the
|
||
system time related functions and macros are now there.
|
||
- CHANGE: Renamed the structure DeltaList to VTList, it includes the system
|
||
time counter too now.
|
||
- CHANGE: Removed the CH_USE_SYSTEMTIME and CH_USE_VIRTUAL_TIMER configuration
|
||
options in order to make the chconf.h file simpler. The related subsystems
|
||
are almost always required and are now always included.
|
||
- Small optimization to the MSP430 serial driver.
|
||
- Improvements to the test code, now a failed assert terminates the test case.
|
||
- Added dependency informations handling to the MSP430 demo Makefile.
|
||
- Removed the performance spreadsheet (it was *very* old) and added a
|
||
directory containing the test reports ./docs/reports. Each report shows the
|
||
results from the latest test run on each target.
|
||
- Small fixes to the documentation.
|
||
|
||
*** 0.7.2 ***
|
||
- NEW: Added a serial driver to the MSP430 port, the MSP430 port now has been
|
||
tested on hardware and passes the test suite.
|
||
- NEW: Added to the MSP demo program the option to run from the internal DCO
|
||
or from an external xtal. The default is the internal DCO.
|
||
- NEW: Added macros to convert from seconds, milliseconds and microseconds to
|
||
system ticks. This improves application code portability among different
|
||
ports.
|
||
- CHANGE: Modified the test suite to use the new time conversion macros.
|
||
- CHANGE: Modified the CM3 startup file in order to implement an early
|
||
initialization phase: hwinit0, the late initialization phase is now named
|
||
hwinit1. The demo now initializes the PLL before initializing the BSS and
|
||
DATA segments, this greatly optimizes the system start up time.
|
||
- NEW: Unified ARM7 startup file, it is shared by the LPC and SAM7 demo
|
||
projects. The new startup file implements early and late initialization
|
||
phases as described above for the CM3 startup file.
|
||
The architecture specific vector tables are now encapsulated into the
|
||
vectors.s files.
|
||
- Modified the STM32 demo makefile to use the latest YAGARTO toolchain as
|
||
default (arm-elf-gcc).
|
||
- Documentation improvements, added collaboration diagrams and call graphs.
|
||
Added a documentation-related readme under ./docs.
|
||
|
||
*** 0.7.1 ***
|
||
- NEW: New chThdInit() and chThdCreateStatic() APIs now replace the old
|
||
chThdCreate() and chThdCreateFast() that are thus marked as deprecated.
|
||
The new APIs use one less parameter and are faster.
|
||
- NEW: New dynamic chThdCreateFromHeap() and chthdCreateFromMemoryPool() APIs.
|
||
The dynamic APIs are only included if the CH_USE_DYNAMIC option is specified
|
||
into the project configuration file.
|
||
- NEW: Added an THREAD_EXT_EXIT macro in chconf.h to add finalization code to
|
||
the chThdExit() API.
|
||
- CHANGE: chThdCreateFast() is now a macro that uses chThdCreateStatic().
|
||
- CHANGE: chThdWait() now releases the memory allocated by
|
||
chThdCreateFromHeap() and chthdCreateFromMemoryPool(). Threads created
|
||
through the static APIs are not affected thus the behavior is backward
|
||
compatible.
|
||
- CHANGE: Modified the chThdResume() API to return the resumed thread pointer
|
||
instead of void. This allowed few optimization into the threads creation
|
||
code.
|
||
- CHANGE: The chThdGetExitEventSource() API and the CH_USE_EXIT_EVENT
|
||
configuration option and the are now deprecated. Use the THREAD_EXT_EXIT
|
||
finalization macro in order to implement a similar functionality if needed.
|
||
- FIX: The chThdCreate() had a regression in 0.7.0, the mode parameter was
|
||
ignored.
|
||
- FIX: Removed duplicated call to chHeapInit() into chSysInit().
|
||
- FIX: Fixed a syntax error in chheap.c triggered by the CH_USE_DEBUG option.
|
||
- Added new test cases to the test suite for the new dynamic APIs.
|
||
- Documentation fixes.
|
||
|
||
*** 0.7.0 ***
|
||
- NEW: Memory Heap Allocator functionality added. The allocator implements a
|
||
first-fit strategy but there is an option that allow it to wrap the compiler
|
||
provided malloc() that may implement a different strategy. The heap
|
||
allocator is thread-safe and can use both a mutex or a semaphore as
|
||
internal synchronization primitive.
|
||
- NEW: Memory Pools functionality added, this mechanism allows constant-time
|
||
allocation/freeing of constant-size objects. It can be used to dynamically
|
||
allocate kernel objects like Semaphores, Mutexes, Threads etc fully in real
|
||
time, of course it is also possible to manage application-defined objects.
|
||
The pool allocator is thread-safe.
|
||
It is worth remembering that the kernel is still entirely static, it does
|
||
not use the allocation services internally, it is up to the application
|
||
code to use the allocators in order to use dynamic system objects.
|
||
Both the allocators can be disabled and removed from the memory image.
|
||
- NEW: Added option macros in chconf.h to add custom fields and initialization
|
||
code to the Thread structure.
|
||
- FIX: Corrected the wrong definition of the chThdResumeI() macro.
|
||
- FIX: The API chSemWaitTimeout() was missing in the documentation.
|
||
- CHANGE: Modified the chMtxUnlock() and chMtxUnlockS() APIs to return the
|
||
pointer to the released mutex instead of void.
|
||
- CHANGE: Now the chThdResume() API asserts that the thread is in PRSUSPEND
|
||
state rather than test it.
|
||
- CHANGE: Removed the CH_USE_TERMINATE, CH_USE_SLEEP, CH_USE_SUSPEND and
|
||
CH_USE_RESUME configuration options in order to make the chconf.h file
|
||
simpler. The related functions are very small and almost always required.
|
||
- CHANGE: The P_MSGBYPRIO thread option has been removed, now the threads
|
||
always serve messages in priority order if the CH_USE_MESSAGES_PRIORITY
|
||
configuration option is active.
|
||
- Added new test cases to the test suite.
|
||
|
||
*** 0.6.10 ***
|
||
- FIX: Fixed a case-sensitiveness error in lpc214x_ssp.c, it affected only
|
||
linux/unix users.
|
||
- FIX: Fixed a regression introduced in version 0.6.9, the queues benchmark
|
||
test case was missing from the tests list.
|
||
- NEW: Added an option to the ARM7 ports, by specifying -DREENTRANT_LOCKS in
|
||
the makefile options makes the chSysLock() and chSysUnlock() become
|
||
reentrant. The code becomes a bit larger and slower, use it only if your
|
||
application really needs to invoke system API under lock.
|
||
- NEW: Added an option to the ARM7 and CM3 makefiles to strip any unused code
|
||
and data from the binary file (the default is on).
|
||
|
||
*** 0.6.9 ***
|
||
- NEW: Added an option to exclude the support for the round robin scheduling,
|
||
this can save some extra program space and makes the context switch a bit
|
||
faster if the feature is not required. Threads at the same priority level
|
||
are still supported when the feature is disabled but the scheduling among
|
||
them becomes cooperative.
|
||
- OPT: Improved reschedule time by reordering the sequence of operations,
|
||
now during enqueuing the ready list contains one less element. This change
|
||
also slightly improves the interrupt latency.
|
||
- OPT: Optimization to the chSemReset(), reversed the order of dequeuing.
|
||
- FIX: Fixed a bug in the chThdSetPriority() API.
|
||
- FIX: Modified the structure names into nvic.h in order to not make them
|
||
collide with external libraries.
|
||
- Added a benchmark to the test suit that measures the mass reschedule
|
||
performance.
|
||
- Added a test_terminate_threads() function to the test framework.
|
||
- Made the Cortex-M3 port preemption code more readable.
|
||
- Added a ENABLE_WFI_IDLE option to the chcore.h file in the Cortex-M3 port,
|
||
setting this option to 1 enables the kernel to enter a low power mode when
|
||
executing the idle thread. Be careful however, this option can be not
|
||
compatible with some JTAG probes, it is better to enable it only on final
|
||
builds and not when debugging.
|
||
|
||
*** 0.6.8 ***
|
||
- FIX: Fixed a bug in the priority inheritance mechanism, the bug was only a
|
||
problems when the CH_USE_MESSAGES_PRIORITY was enabled, this option is
|
||
disabled by default in ChibiOS/RT so it should not affect any user.
|
||
- CHANGE: The function chEvtSend() and chEvtSendI() are now renamed in
|
||
chEvtBroadcast() and chEvtBroadcastI(), the old names are still available
|
||
but are deprecated.
|
||
- Made the default BASEPRI levels (CM3 port) configurable into chcore.h.
|
||
- Many improvements to the documentation.
|
||
- All the fixes and changes in this release were suggested/submitted by
|
||
Leon Woestenberg (thank you).
|
||
|
||
*** 0.6.7 ***
|
||
- NEW: New chThdCreateFast() API, it is a simplified form of chThdCreate()
|
||
that allows even faster threads creation. The new API does not support
|
||
the "mode" and "arg" parameters (still available in the old API).
|
||
- OPT: Removed an unrequired initialization and made other small optimizations
|
||
to the chThdCreate().
|
||
- OPT: Improvements to the test framework, now a virtual timer is used instead
|
||
of software loops into the benchmarks in order to have more stable results.
|
||
- New benchmark added to the test suite.
|
||
- Added the C++ wrapper entries to the documentation.
|
||
- Fixed the documentation entry for the chThdCreate() API.
|
||
- Removed redundant ifdefs from the ch.h header.
|
||
|
||
*** 0.6.6 ***
|
||
- NEW: Improved test suite, now the suite is divided in modules and the code
|
||
is much easier to understand. The new framework simplifies the inclusion of
|
||
new test cases and makes possible to verify the exact sequence and the
|
||
timing of test events.
|
||
- NEW: New API chSysInTimeWindow() that checks if the current system time is
|
||
within the specified time window.
|
||
- FIX: Mutex test #1 in the test suite corrected, it failed to... fail.
|
||
- FIX: Fixed a problem in the STM32 port USART1 driver.
|
||
- FIX: Fixed a problem in the MMC/SD driver in the LPC2148 demo.
|
||
- Added the definitions for packed structures to the chtypes.h files.
|
||
- Improvements to the makefiles, now each source group has its own .mk include
|
||
file. Now it is no more required to rewrite everything in each makefile.
|
||
|
||
*** 0.6.5 ***
|
||
- NEW: Web server demo for the AT91SAM7X256, the demo integrates the uIP
|
||
stack and its demo applications.
|
||
- NEW: EMAC driver added to the AT91SAM7X port.
|
||
- FIX: Small fix to the ARM7 startup files. It used a short jump in the reset
|
||
vector and that could fail in some memory configurations.
|
||
- Documentation improvements.
|
||
|
||
*** 0.6.4 ***
|
||
- NEW: MSP430 port, the port code compiles correctly but it is not tested yet.
|
||
The port requires the MSPGCC toolchain.
|
||
- NEW: Added a CH_ARCHITECTURE_xxx define to the various chcore.h files, it
|
||
allows to write port-dependent code.
|
||
- NEW: Added to the documentation the technical notes about the currently
|
||
supported ports.
|
||
- FIX: In the ARM7 and ARMCM3 ports chanced the bool_t base type from int8_t
|
||
to int32_t, this produces a bit faster and smaller code.
|
||
It is nowhere required the bool_t type to be one byte sized.
|
||
- FIX: Small fixes to the template files, there were some leftovers of the old
|
||
type names.
|
||
- FIX: Modified the ARM demos makefiles in order to make them more compatible
|
||
with GCC 4.3.0, it seems the new GCC assumes -mthumb-interworking and
|
||
-mabi=apcs by default, at least the builds I tested did so, now the makefiles
|
||
explicitly assert -mno-thumb-interworking and -mabi=apcs-gnu in order to
|
||
produce better code.
|
||
- Added an Ethernet driver for AT91SAM7X EMAC, not complete yet, it will be
|
||
required by a uIP web server demo under ChibiOS/RT coming in some next
|
||
release.
|
||
|
||
*** 0.6.3 ***
|
||
- NEW: ARM Cortex-M3 port completed. The demo program targets the STM32F103
|
||
chip from ST Microelectronics on an Olimex STM32-P103 board.
|
||
- FIX: Fixed a minor error in ./ports/ARM7-LPC214x/vic.h, it should not affect
|
||
anything.
|
||
- FIX: Minor fix: in chThdCreate() a working area size equal to
|
||
UserStackSize(0) was asserted as an error when in debug mode. It is now
|
||
allowed.
|
||
- FIX: Increased the stack size for the threads in the test suite to 128 bytes
|
||
because THUMB/THUMB2 modes seem to use a lot more stack than ARM mode.
|
||
|
||
*** 0.6.2 ***
|
||
- NEW: Added C++ wrapper around the ChibiOS/RT core APIs, now it is possible
|
||
to use the OS in a fully object oriented application. The wrapper offers
|
||
classes that encapsulate threads, semaphores, mutexes, timers etc. Normal C
|
||
APIs are still accessible from C++ code as usual.
|
||
- NEW: Added a new LPC2148 demo using the new C++ wrapper, it is a good
|
||
example of C++ used for an embedded application. The demo does not use RTTI
|
||
nor standard libraries so the resulting code is very compact.
|
||
- Enhanced the chSemSignalWait() API to return the wakeup message just like
|
||
the other "Wait" semaphore functions do.
|
||
- Fixed a minor problem in the ARM7 port, the extctx structure definition was
|
||
missing one field, the effect was to allocate stacks 4 bytes shorter than
|
||
the declared size.
|
||
- Fixed a compile time error into the chThdSleepUntil() macro.
|
||
- Fixes in various headers to make some macros compatible with both C and C++.
|
||
- Fixed a regression in the LPC214x minimal demo that broke interrupt
|
||
handling.
|
||
- Some fixes to the doxygen documentation.
|
||
- More work done on the ARM-CM3 port but it is still not complete.
|
||
|
||
*** 0.6.1 ***
|
||
- Removed some redundant checks from the scheduler code: improved threads
|
||
flyback time, reduced interrupts service time.
|
||
- Nice scheduler speed improvement obtained by removing the 2nd parameter to
|
||
the chSchReadyI() API and manually assigning the message value only where
|
||
is really needed (very few points in the code).
|
||
- More space savings and speed improvements obtained by removing the
|
||
-fno-strict-aliasing option from the makefiles, now the kernel compiles
|
||
without any warning even without this option.
|
||
- Removed the -falign-functions=16 option from the AT91SAM7X demo makefiles,
|
||
the Atmel chip does not require it, the option is still present on the
|
||
LPC21xx demos. This saves significant program space.
|
||
- Started work on ARM Cortex-M3 architecture. The target chip is the STM32F103
|
||
on a Olimex STM32-P103 board.
|
||
- Added a threads state diagram to the documentation.
|
||
- Various fixes to the doxygen documentation.
|
||
|
||
*** 0.6.0 ***
|
||
- Code refactory, all the old sized-integer definitions like LONG32, UWORD16
|
||
etc are now replaced by the proper definitions provided by the compiler
|
||
into stdint.h.
|
||
- Code refactory, the previous system types style using a t_ in front of the
|
||
name has been replaced with the standard trailing _t. The system now uses
|
||
the size_t type defined into stddef.h. Some type names were modified in
|
||
order to not match commonly used type names.
|
||
- The above changes have an impact on some API prototypes but we can't help
|
||
it, the changes were required because the type names were a concern for
|
||
some users.
|
||
- Implemented a serial driver in the AVR port.
|
||
- Implemented a simple HD44780 LCD driver into the AVRmega128 demo.
|
||
- Reworked the AVR AT90CAN128 port to share the common AVR code.
|
||
- Modified the test suite to be compatible with 8 bit micros.
|
||
- MSVC demo dropped, it is still possible to use the MinGW demo as simulator
|
||
in Win32.
|
||
- Fixed a minor error in sam7x_serial.h and lpc214x_serial.h.
|
||
- The kernel is *unchanged* compared to version 0.5.3 except for the type
|
||
names but the change is important enough to make this a recommended update.
|
||
|
||
*** 0.5.5 ***
|
||
- Added an AVRmega128 port. The previous AT90CANx port is still present but
|
||
it will be redone after the AVRmega128 port is complete because it will
|
||
share most of it. The demo is very simple, it will be expanded in next
|
||
releases.
|
||
- Reorganized the code of the two ARM7 ports, now all the common ARM7 code
|
||
is in ./ports/ARM7. This will make maintenance and new ARM7 ports much much
|
||
easier.
|
||
- Simplified the directory structure under ./ports.
|
||
- Added to the readme a section with our future plans/ideas.
|
||
- The kernel is *unchanged* compared to version 0.5.3, just the new port and
|
||
the new demo were added.
|
||
|
||
*** 0.5.4 ***
|
||
- Port for Atmel AT91SAM7X256 introduced, the port should be usable also on
|
||
SAM7S and SAM7XC but no tests were performed. Other SAM7 processors should
|
||
also be usable with limited changes.
|
||
The demo currently just performs basic operations, will be enhanced in next
|
||
ChibiOS/RT releases, see the demo readme.txt file.
|
||
- Small fix to the thumb mode IRQ code on the LPC214x port, removed some extra
|
||
code.
|
||
- The kernel is *unchanged* compared to version 0.5.3, just the new port and
|
||
the new demo were added.
|
||
|
||
*** 0.5.3 ***
|
||
- Removed the chMsgSendTimeout() API, it was conceptually flawed because,
|
||
after sending a message, the sender *has* to wait for the answer or
|
||
the next sender in queue would receive it instead (the messages server has
|
||
no way to know that the sender is gone because a timeout).
|
||
A workaround would make the messages subsystem much heavier and this is
|
||
not acceptable.
|
||
- Removed the test case for chMsgSendTimeout() from the test suite.
|
||
- Space saved by reorganizing the timeout code into a single scheduler
|
||
function chSchGoSleepTimeoutS().
|
||
- Space optimizations in the semaphores code.
|
||
- The API chThdSleepUntil() become a macro saving some more code space.
|
||
- Because all the above changes the kernel code (ARM) is over 700 bytes
|
||
smaller.
|
||
|
||
*** 0.5.2 ***
|
||
- Fixed a small problem in the main header file ch.h.
|
||
- Small reordering in the fields of the Thread structure in order to optimize
|
||
the space when messages are not used.
|
||
|
||
*** 0.5.1 ***
|
||
- NEW: Priority enqueing for messages can be optionally enabled by specifying
|
||
the P_MSGBYPRIO option when creating a message server thread.
|
||
This change allows the implementation of a priority ceiling protocol into
|
||
message servers threads. Threads serving messages by priority and threads
|
||
serving messages in FIFO order can exist at the same time in the system.
|
||
This feature can be enabled or disabled by toggling the option
|
||
CH_USE_MESSAGES_PRIORITY into the chconf.h file (disabled by default, old
|
||
behavior).
|
||
Note: This option brings a small overhead when sending a message regardless
|
||
if in FIFO or priority order, if you don't need priority ordering for your
|
||
messages it is better to keep the feature disabled in chconf.h.
|
||
- Added to the ARM demos load scripts the capability to load code in RAM
|
||
instead flash, the function must be marked as:
|
||
__attribute__((section(".ramtext")))
|
||
The option -mlong-calls should be specified in the makefile too or the
|
||
function declared with the "long-call" attribute.
|
||
- Fixed the MSVC demo project files.
|
||
- Fixed some syntax incompatibilities between GCC and MSVC into chmtx.c.
|
||
|
||
*** 0.5.0 ***
|
||
- NEW: Mutexes, the new mechanism provides a complete implementation of the
|
||
"priority inheritance" algorithm as a tool for work around the priority
|
||
inversion problem.
|
||
The Mutexes are not meant to replace the Semaphores that still are the best
|
||
synchronization mechanism between interrupt handlers and high level
|
||
code, something that Mutexes cannot do.
|
||
Soon an article will be added to the wiki describing pro and cons of the
|
||
various mechanisms and the correct use cases.
|
||
- RT Semaphores subsystem removed, the Mutexes implements a better solution
|
||
for the same problem.
|
||
- Fixed a bug in the round robin scheduling mode, see the bug tracker for
|
||
details and a fix for previous versions.
|
||
- More performance improvements to the scheduler. The ready list insertion
|
||
sequence is now reversed, it is scanned starting from the highest priority
|
||
end. This has an important side effect into the chSchWakeupS() that makes
|
||
most of the ready list insertions happen in constant time (extraction is
|
||
done always in constant time).
|
||
The worst case is always proportional to the number of threads in the ready
|
||
list but the normal case is much more often constant than linear. See the
|
||
new benchmarks added to the test suite.
|
||
- Added mutexes test cases and new benchmarks to the test suite.
|
||
- Modified the test suite in order to have each test case to have the same
|
||
alignment enforced on functions. This is done to reduce MAM/Cache alignment
|
||
effects on the measurement.
|
||
- IRQ entry/exit code is now encapsulated into two new macros, see chcore.h
|
||
for details.
|
||
- All the asm code previously in chcore2.s is now inline asm code in chcore.c
|
||
(ARM port), chcore2.s removed.
|
||
- Moved all the board specific definitions/code into two new files: board.c
|
||
and board.h. Moved all the files no more board-dependent under ports/
|
||
(ARM port).
|
||
- Improved the kernel performance in THUMB mode by better exploiting MAM
|
||
locality in some critical functions. The context switch benchmark shows
|
||
5% improved speed.
|
||
|
||
*** 0.4.5 ***
|
||
- Moved the serial IRQ handlers and VIC vectors initialization inside the
|
||
serial drivers. Now the serial-related code is all inside the driver.
|
||
- Moved all the other interrupt handlers from chcore2.s into chcore.c as
|
||
inline asm code. The interrupt code now is faster because one less call
|
||
level.
|
||
- Fixed a minor problem in chSysHalt() now it disables FIQ too and makes sure
|
||
to keep the processor in the state it had when it was halted.
|
||
Note: This is not a kernel bug but something specific with the ARM port, the
|
||
other ports are not affected.
|
||
- Fixed the macro chThdResumeI(), it had a regression.
|
||
|
||
*** 0.4.4 ***
|
||
- Fixed a very important bug in the preemption ARM code, important enough to
|
||
make this update *mandatory*.
|
||
Note: This is not a kernel bug but something specific with the ARM port, the
|
||
other ports are not affected.
|
||
- Fixed a nasty bug in the pure THUMB mode threads trampoline code (chcore2.s,
|
||
threadstart), it failed on THUMB threads returning with a "bx" instruction.
|
||
The bug did not affect ARM mode or THUMB with interworking mode.
|
||
Note: This is not a kernel bug but something specific with the ARM port, the
|
||
other ports are not affected.
|
||
- Fixed a bug in chIQGetTimeout(), interrupts were not re-enabled when exiting
|
||
the function because a timeout. The problem affected that API only.
|
||
- Fixed a potential problem in chSysInit(), it should not affect any past
|
||
application.
|
||
- Added a chDbgAssert() API to the debug subsystem.
|
||
- Cleaned up the kernel source code using chDbgAssert() instead of a lot of
|
||
"#ifdef CH_USE_DEBUG", it is much more readable now.
|
||
- Now the threads working area is filled with a 0x55 when in debug mode, this
|
||
will make easier to track stack usage using a JTAG probe.
|
||
- Added an I/O Queues benchmark to the test suite.
|
||
- Removed the chSchTimerHandlerI() routine from chschd.c and moved it into
|
||
chinit.c renaming it chSysTimerHandlerI() because it is not part of the
|
||
scheduler.
|
||
|
||
*** 0.4.3 ***
|
||
- Size optimization in the events code, now the chEvtWait() reuses the
|
||
chEvtWaitTimeout() code if it is enabled.
|
||
- Size optimization in the semaphores code, now the chSemWaitTimeout() just
|
||
invokes the chSemWaitTimeoutS() inside its system mutex zone. Same thing
|
||
done with chSemWait() and chSemWaitS().
|
||
- Size optimization in the queues code.
|
||
- Modified the return type of chSemWait() and chSemWaitS() from void to t_msg,
|
||
this allows to understand if the semaphore was signaled or reset without
|
||
have to access the Thread structure.
|
||
- Added a threads create/exit/wait benchmark to the test suite, the system
|
||
is capable of 81712 threads started/terminated per second on the reference
|
||
LPC2148 board. The figure is inclusive of two context switch operations
|
||
for each thread.
|
||
- Minor improvement in the LPC214x serial driver, unneeded events were
|
||
generated in some rare cases.
|
||
- Fixed a chSysInit() documentation error.
|
||
- Fixed a chEvtWaitTimeout() documentation error.
|
||
- Added a new debug switch: CH_USE_TRACE, previously the trace functionality
|
||
was associated to the CH_USE_DEBUG switch.
|
||
|
||
*** 0.4.2 ***
|
||
- Added a minimal ARM7-LPC demo, you can use this one as template in order to
|
||
create your application. It is easier to add subsystems back to the small
|
||
demo than remove stuff from the large one.
|
||
- Introduced support for "pure" THUMB mode, it is activated when all the
|
||
source files are compiled in THUMB mode, the option -mthumb-interworking is
|
||
not used in this scenario and this greatly improves both code size and
|
||
speed.
|
||
It is recommended to either use ARM mode or THUMB mode and not mix them
|
||
unless you know exactly what you are doing. Mixing modes is still supported
|
||
anyway.
|
||
- More optimizations in the scheduler, updated the performance spreadsheet.
|
||
- Fixed a problem with the thread working area declarations, the alignment to
|
||
4 bytes boundary was not enforced. Now it is defined a new macro
|
||
WorkingArea(name, length) that takes care of both the allocation and the
|
||
alignment.
|
||
Example:
|
||
static WorkingArea(waThread1, 32);
|
||
It is expanded as:
|
||
ULONG32 waThread1[UserStackSpace(32) >> 2];
|
||
Now the demos use the new declaration style.
|
||
- Fixed a small problem in sleep functions introduced in 0.4.1.
|
||
|
||
*** 0.4.1 ***
|
||
- Modified the initialization code in order to have a dedicated idle thread in
|
||
the system, now the main() function behaves like a normal thread after
|
||
executing chSysInit() and can use all the ChibiOS/RT APIs (it was required
|
||
to run the idle loop in previous versions).
|
||
Now it is also possible to use ChibiOS/RT with a single main() thread and
|
||
just use it for the I/O capabilities, Virtual Timers and events. Now you
|
||
don't have to use multiple threads if you don't really need to.
|
||
- Added a spreadsheet in the documentation that describes the advantages
|
||
and disadvantages of the various optimization options (both GCC options and
|
||
ChibiOS/RT options), very interesting read IMO.
|
||
- The GCC option -falign-functions=16 is now default in the Makefile, it is
|
||
required because of the MAM unit into the LPC chips, without this option
|
||
the code performance is less predictable and can change of some % points
|
||
depending on how the code is aligned in the flash memory, unpredictability
|
||
is bad for a RTOS. This option however increases the code size slightly
|
||
because of the alignment gaps.
|
||
- Fine tuning in the scheduler code for improved performance, deeper
|
||
inlining and other small changes, about 5% better scheduler performance.
|
||
- Increased the default system-mode stack size from 128 to 256 bytes because
|
||
some optimizations and the THUMB mode seem to eat more stack space.
|
||
- Included a Makefile in the LPC2148 demo that builds in THUMB mode.
|
||
- Const-ified a parameter in the chEvtWait() and chEvtWaitTimeout() APIs.
|
||
- Removed the CPU register clearing on thread start, it was not really useful,
|
||
it is better to maximize performance instead.
|
||
- Cleaned up the ARM port code. Now it is easier to understand.
|
||
- Cleaned up the LPC2148 demo in main.c, it is now well documented and
|
||
explains everything, I assumed too much stuff to be "obvious".
|
||
|
||
*** 0.4.0 ***
|
||
- NEW, added a benchmark functionality to the test suite. The benchmark
|
||
measures the kernel throughput as messages per second and context switches
|
||
per second. The benchmark will be useful for fine tuning the compiler
|
||
options and the kernel itself.
|
||
- NEW, implemented a debug subsystem, it supports debug messages and a context
|
||
switch circular trace buffer. The debug code can be enabled/disabled by
|
||
using the CH_USE_DEBUG in chconf.h.
|
||
The trace buffer is meant to be fetched and decoded by an external tool
|
||
(coming soon, it can be accessed using JTAG in the meanwhile).
|
||
- Added new API chThdGetPriority() as a macro.
|
||
- Implemented panic messages when CH_USE_DEBUG is enabled.
|
||
- Added a thread identifier field to the Thread structure, it is used only
|
||
for debug.
|
||
- Global variable stime modified as volatile.
|
||
- API chSysGetTime() reimplemented as a macro.
|
||
- Fixed a regression with the CH_CURRP_REGISTER_CACHE option.
|
||
- Fixed a problem in the LPC2148 interrupt handling code, a spurious
|
||
interrupts fix recommended on the NXP data sheet proved to be a very bad
|
||
idea and not about real spurious interrupts also...
|
||
- Fixed an harmless warning message in buzzer.c.
|
||
|
||
*** 0.3.6 ***
|
||
- Added SSP (SPI1) and ext.interrupts definitions to the lpc214x.h file.
|
||
- Added SSP driver for the LPC2148.
|
||
- Added experimental MMC/SD block driver to the LPC2148 demo in order to
|
||
support file systems. The driver features also events generation on card
|
||
insert/remove, hot plugging supported.
|
||
- Added missing chThdSuspend() declaration in threads.h.
|
||
|
||
*** 0.3.5 ***
|
||
- Space optimization in events code.
|
||
- Changed the behavior of chEvtWaitTimeout() when the timeout parameter is
|
||
set to zero, now it is consistent with all the other syscalls that have a
|
||
timeout option.
|
||
- Reorganized all the kernel inline definitions into a single file (inline.h).
|
||
- Fixed a minor problem in the interrupt initialization code for the LPC214x
|
||
demo, regrouped the VIC-specific code into vic.c/vic.h.
|
||
- Fixed a bug into the LPC2148 serial driver (limited to the serial port 2).
|
||
- Implemented HW transmit FIFO preloading in the LPC2148 serial driver in
|
||
order to minimize the number of interrupts generated, it is possible to
|
||
disable the feature and return to the old code which is a bit smaller, see
|
||
the configuration parameters in ./ARM7-LPC214x/GCC/lpc214x_serial.h.
|
||
- Some more work done on the AVR port, it is almost complete but not tested
|
||
yet because my JTAG probe broke...
|
||
|
||
*** 0.3.4 ***
|
||
- Fixed a problem in chVTSetI().
|
||
- New API, chVTIsArmedI(), it is a macro in delta.h.
|
||
- New API, chThdResumeI(), it is a macro in threads.h. This function is just
|
||
an alias for chSchReadyI() but makes the code more readable.
|
||
- New API, chThdSuspend(). New switch CH_USE_SUSPEND added to chconf.h.
|
||
|
||
*** 0.3.3 ***
|
||
- Modified the chVTSetI(), now for the "time" parameter can have value zero
|
||
with meaning "infinite". This allows all the APIs with timeout parameters
|
||
to be invoked with no timeout.
|
||
- Fixes in the documentation.
|
||
- Renamed some APIs in the "Sch" group to have an S suffix instead of I.
|
||
|
||
*** 0.3.2 ***
|
||
- Modified the chSysInit() to give the idle thread absolute priority, the
|
||
priority is then lowered to the minimum value into the chSysPause(). This
|
||
is done in order to ensure that the initializations performed into the
|
||
main() procedure are finished before any thread starts.
|
||
- Added chThdSetPriority() new API.
|
||
- Added a generic events generator timer module to the library code.
|
||
- Modified the ARM7-LPC214x-GCC demo to show the use of the event timer.
|
||
- Added the "#ifdef __cplusplus" stuff to the header files.
|
||
- Removed an obsolete definition in ./src/templates/chtypes.h.
|
||
|
||
*** 0.3.1 ***
|
||
- Test program added to the demos. Telnet the MinGW and MSVS demos and type
|
||
"test" at the "ch>" prompt. On the LPC214x demo the test is activated by
|
||
pressing both the board buttons. The test performs tests on the ChibiOS/RT
|
||
functionalities.
|
||
The test code is also a good example of APIs usage and ChibiOS/RT behavior.
|
||
- Fixed bug in chEvtWaitTimeout(), the timeout code performed an useless
|
||
dequeue operation.
|
||
- Fixed a bug in chSemWaitTimeoutS() and chSemWaitTimeout(), the semaphore
|
||
counter was not atomically updated on a timeout condition.
|
||
- Fixed bug on RT semaphores, the priority queuing was broken.
|
||
- Fixed a bug in the MinGW demo, the chThdExit() code was not correctly
|
||
reported to the thread waiting in chThdWait().
|
||
- Fixed a function declaration in semaphores.h.
|
||
- Lists code moved into chlists.c from various other places optimized and
|
||
reorganized.
|
||
- The list of the threads waiting in chThdWait() is now a single link list,
|
||
this saves some space.
|
||
- Cleaned the template files code, the files contained some obsolete
|
||
declarations.
|
||
- Code optimization in chSemWaitTimeoutS(), chSemWaitTimeout() and
|
||
chSemSignalWait().
|
||
- Code optimization in chEvtSend().
|
||
- Code optimization in chVTDoTickI().
|
||
- Added a Semaphore pointer to the Thread structure, this allows to know on
|
||
which semaphore a thread is waiting on. It takes no space because it is
|
||
located in the union inside the Thread structure. This also allowed a minor
|
||
optimization inside chSemWaitTimeout() and chSemWaitTimeoutS().
|
||
- Changed the priority type to unsigned in order to make it compatible
|
||
with a byte value, this is very important for 8 bits architectures.
|
||
- Modified the MinGW and MSVS demos to use 1ms ticks instead of 10ms as
|
||
before.
|
||
|
||
*** 0.3.0 ***
|
||
- ChibiOS/RT goes beta.
|
||
- Diet for the threads code, some simple APIs become macros.
|
||
- Thread Local Storage implemented as a single API: chThdLS().
|
||
The API simply returns a pointer into the thread working area, see the
|
||
documentation on the web site.
|
||
- Moved some documentation and images from the web site into the Doxygen
|
||
generated HTMLs.
|
||
|
||
*** 0.2.1 ***
|
||
- Optimizations in the RT semaphores subsystem. The support for this
|
||
subsystem should still be considered experimental and further changes may
|
||
happen in future versions.
|
||
- Bug fix in the virtual timers handling code, now the timers can be re-armed
|
||
from within the callback code in order to create periodic virtual timers.
|
||
- Modified the t_prio type in the demos to be 32bits wide instead of 16bits,
|
||
this results in a better code in critical sections of the kernel.
|
||
|
||
*** 0.2.0 ***
|
||
- Introduced support for ARM in thumb mode.
|
||
- Optimized context switching when thumb-interworking is not required, one
|
||
less instruction.
|
||
- Minor fixes to the ARM demo.
|
||
|
||
*** 0.1.1 ***
|
||
- Some fixes into the documentation
|
||
- Renamed the makefiles to Makefile, upper case M.
|
||
|
||
*** 0.1.0 ***
|
||
- First alpha release
