*** 2.2.3 ***
- FIX: Fixed insufficient idle thread stack in Cortex-M0-GCC port
(bug 3226671).
- FIX: Fixed stack checking in Cortex-M0-GCC port (bug 3226657).
- FIX: Fixed wrong checks in PAL driver (bug 3224681).
- FIX: Fixed wrong checks in I/O Queues (bug 3219197).
- FIX: Fixed invalid assertion in adcConvert() (bug 3205410).
- NEW: Implemented stack checking in the Cortex-Mx RVCT port.
- 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.
*** 2.2.2 ***
- FIX: Fixed race condition in CM0 ports, the fix also improves the
ISR latency (bug 3193062).
- 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).
- FIX: Fixed error in function chCoreAllocI() function documentation (bug
3191107).
- FIX: Fixed minor problem with memory pools (bug 3190512).
- NEW: Added I-Class functions to the MailBoxes subsystem, now it is
possible to use them as a transport layer between ISRs and Threads.

- FIX: Fixed PWM channels return to IDLE state in STM32 PWM driver (bug
3114467).
- CHANGE: Bugs 3114467 and 3114481 have been fixed by backporting the 2.1.x
PWM driver, there is a difference in the PWM callback parameters.

- FIX: Fixed broken CH_DBG_ENABLE_STACK_CHECK option in legacy CM3 port (bug
3064274).
- FIX: Fixed CAN_USE_SLEEP_MODE setting (bug 3064204).
*** 2.0.4 ***
- FIX: Fixed potential issue with GCC reorganizing instructions around "asm
volatile" statements (bug 3058731).
- FIX: Fixed reduced ARM7 performance with GCC 4.5.x (bug 3056866).
*** 2.0.3 ***
- Tests reports regenerated using GCC 4.5.1, small performance improvements
in all benchmarks.
- FIX: Fixed crash of the Posix simulator under Ubuntu 10.4 (bug 3055329).

- FIX: Fixed STM32 vectors file (bug 3026528).
- FIX: Fixed race condition in STM32 SPI driver (bug 3025854).
- FIX: Fixed H_LOCK and H_UNLOCK redefined with CH_USE_MALLOC_HEAP (bug
3025549).
- FIX: Added option to enforce the stack alignment to 32 or 64 bits in the
Cortex-Mx port (bug 3025133).
- NEW: Added friendly interrupt vectors names to the STM32 HAL (change request
3023944).
- 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".
*** 2.0.1 ***
- FIX: Fixed notification order in input queues (bug 3020708).
- FIX: Fixed non functional CH_CURRP_REGISTER_CACHE option in the Cortex-M3
port (bug 3020702).
- 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).
- FIX: Fixed insufficient stack space assigned to the idle thread in
Cortex-M3 port (bug 3019594).
- FIX: Fixed missing check in chIQReadTimeout() and chIQWriteTimeout() (bug
3019158).
- FIX: Fixed instability in Mutexes subsystem (bug 3019099).
- NEW: Added timers clock macros to the STM32 clock tree HAL driver.
*** 2.0.0 ***
- 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 a PowerPC port and demo targeting the SPC563M/MPC563xM
ST/Freescale automotive SOCs.
- NEW: Added STM8 port and demo targeting the Raisonance REva board
with STM8S208RB piggyback.
- NEW: New unified ARM Cortex-Mx port, this port supports both the ARMv6M
and ARMv7-M architectures (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: 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 support for STM32/HD/CL UART4 and UART5, thanks Egon for the
patch.
- NEW: Embedded Artists LPCxpresso Base Board support files added.
- NEW: LPC11xx support, drivers (Serial, PAL, HAL) and demo.
- NEW: LPC13xx support, drivers (Serial, PAL, HAL), demo and reports.
- 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: Updated the STM32 FW Library files to latest version 3.3.0.
- NEW: AT91SAM7 HAL support for the DGBU UART peripheral, as SD3.
- NEW: Added a demo for the AT91SAM7S256 and board files for the Olimex
SAM7-P256. The demo has been contributed by Alexander Kozaruk.
- 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.
- 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.
- 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.
- NEW: New articles and guides in the documentation.
- 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.
- 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.
- OPT: Small size optimization in the semaphores subsystem.
- OPT: Minor optimizations in the "compact" code path.
- 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.
- OPT: Internal optimization in the serial driver, it now is a bit smaller
and uses less RAM (all architectures).
*** 1.4.3 ***
- FIX: Fixed centralized ARM makefile (bug 2992747).
- FIX: Fixed write problems in MMC_SPI driver (bug 2991714).
- FIX: Fixed wrong macro check in serial.h (bug 2989459).
*** 1.4.2 ***
- FIX: Fixed missing reschedule in chEvtSignal() (bug 2961208).
- FIX: Removed C99-style variables declarations (bug 2964418).
- Minor documentation fixes.
*** 1.4.1 ***
- FIX: Fixed wrong UART deinitialization sequence in LPC214x serial driver
(bug 2953985).
- FIX: Fixed wrong PINSEL2 offset into lpc214x.h (bug 2953981).
- FIX: Fixed invalid UART-related macro in the LPC214x HAL (bug 2953195).
- FIX: Wrong prototype in template file chcore.c (bug 2951529).
- FIX: Fixed insufficient stack space for the idle thread in the ARMCM3 port
when compiling without optimizations (bug 2946233).
- FIX: Fixed wrong notes on function chThdResume() (bug 2943160).
- FIX: Fixed missing dependencies check for CH_USE_DYNAMIC (bug 2942757).

- NEW: Improvements to the AT91SAM7 support.
- NEW: Improved makefiles and makefile fragments, now the paths are not fixed.
- 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: Hardware Abstraction Layer (HAL) with support for PAL, ADC, CAN, MAC,
MMC/SD, PWM, Serial, SPI drivers. Added driver implementations to the
various platforms.
- NEW: Added support for uIP, lwIP, FatFS external libraries, added demos.
- Many many other improvements and minor features.
*** 1.2.4 ***
- FIX: Fixed GCC 4.4.x aliasing warnings (bug 2846336).
- FIX: Modified linker scripts for GCC 4.4.x (bug 2846302).
- FIX: Fixed the CH_OPTIMIZE_SPEED option in the CM3 port (bug 2846278).
- FIX: Fixed GCC 4.4.x related problems in CM3 port (bug 2846162).
- FIX: Fixed LPC214x UART problem (bug 2841088).
*** 1.2.3 ***
- FIX: Fixed C99-style variable declarations (bug 2792919).
- FIX: Fixed instance of obsolete CH_USE_TERMINATE option in the C++ wrapper
(bug 2796065).
- FIX: Insufficient stack allocated to the C++ LPC2148 demo (bug 2796069).
- FIX: Fixed errors in events test case (bug 2796081).
- 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.
*** 1.2.2 ***
- FIX: Fixed macro in test.h (bug 2781176).
- FIX: Fixed @file tag in sam7x_serial.c (bug 2788573).
- FIX: Fixed sequence assertion in test.c (bug 2789377).
- FIX: Fixed test_cpu_pulse() incorrect behavior (bug 2789383).
- FIX: Fixed missing volatile modifier for p_time field in Thread structure
(bug 2789501).
- CHANGE: Made the option CH_DBG_THREADS_PROFILING default to TRUE because it
is now required in order to execute the whole test suite. Note that this
option is very light so there is no real overhead in the system.
- Added a (harmless) workaround to the Cortex-M3 startup file in order to
make the RIDE7 demo compile on an unmodified distribution.
*** 1.2.1 ***
- FIX: Fixed regression in MinGW demo (bug 2745153).
- FIX: Fixed problem with the timeout constant TIME_IMMEDIATE (bug 2755170).
- FIX: Fixed a problem in semaphores test case #2 (bug 2755195).
- FIX: Removed unused list functions (bug 2755230).
- FIX: Added the exception notes into the source headers (bug 2772129).
- FIX: Added license notice to several files (bug 2772160).
- FIX: Found new instances of the obsolete function chSysGetTime() in the
C++ wrapper and in the WEB demo (bug 2772237).
*** 1.2.0 ***
- Full test cycle and test reports updated.
- 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, as 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.
- 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.
- 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).
- 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.
- 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.
- CHANGE: Changed the chSemFastWaitS() macro in chSemFastWaitI() and
chSemGetCounter() in chSemGetCounterI().
- 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).
- 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.
- 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.
*** 1.0.2 ***
- FIX: Fixed priority inheritance problem with condvars (bug 2674756).
- FIX: Fixed a problem in time ranges (bug 2680425).
- Replaced ./docs/index.html with a direct shortcut to the documentation.
*** 1.0.1 ***
- NEW: Added to the STM32 demo makefile an option to build ChibiOS/RT with the
full STM32 FWLib 2.03.
Note that, except for the compile option, the library is not used by the
OS nor supported.
- FIX: Fixed a problem into the STACK_ALIGN() macro.
- FIX: Fixed a problem with a wrong declaration of the PLL structure in the
file lpc214x.h.
- FIX: Modified the default value for the STM32 HSI setup it was 1, it should
be 0x10.
- FIX: Removed an obsolete constant (P_SUSPENDED) from thread.h.
- FIX: Removed unused field mp_grow in the MemoryPool structure.
