-- 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. Date and time also
- added.
-- 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).

-- 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).

- 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.

- (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

- 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.

-- NEW: Now the STM32 CAN driver puts the lower half word of the ESR
- 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.

-- 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

- 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 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).

-- 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

- (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.

-- 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).

-- 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
