abstraction layer is meant to unify the access protocol to the SDC and
MMC_SPI (and potentially others) device drivers.
- NEW: Added an abstract interface for serial devices in the HAL. This
interface is meant to replace the equivalent class already present in the
kernel. access macros are similar except for the prefix, "chn" instead
of "chIO".
- NEW: Updated the MSP port to work with the latest MSPGCC compiler (4.6.3
LTS 20120406 unpatched), now the old MSPGCC 3.2.3 is no more supported
(backported to 2.4.1).
- NEW: EXT driver improved, now it is possible to reprogram channels at
runtime without necessarily specifying a new configuration.
TODO: Update AT91SAM7 EXT driver.
- NEW: Integrated FatFS 0.9, now the FatFS integration files are centralized
under ./os/various/fatfs_bindings and shared among all demos. The FatFS
file ffconf.h is now application-specific like all the other configuration
files.
- NEW: Added an new option CORTEX_PRIGROUP_INIT to the Cortex-Mx ports in
order to make priority organization configurable, the default is to
assign all the available priority bits to preemption priority with no
sub-priorities.
- NEW: Added a new function chPoolLoadArray() to the Memory Pools subsystem,
it allows to load an entire array element's into a pool with a single
operation.

time slice when preempted. Each thread has its own time slices counter.
TODO: Seek optimizations.
- NEW: Modified the Virtual Timers management, now the callback is invoked
not in lock mode. This change reduces the interrupt jitter caused by
multiple timers used at same time.
- NEW: Added board files and demo for Olimex LPC-P1343 (contributed by
Johnny Halfmoon).
- NEW: Added handling of input 2 to the STM32 ICU driver (contributed by
Fabio).
- NEW: STM32 Ethernet driver completed. Added STM32F107 and STM32F407
lwIP demos (backported to 2.4.1).
- NEW: lwIP related code is not centralized into a single place, no need to
duplicate the code in each application or demo (backported to 2.4.1).
- CHANGE: Added two new methods to the BaseSequentialStream interface:
chSequentialStreamPut() and chSequentialStreamGet().
- CHANGE: Removed the chioch.h header from the kernel, now channels interface
is exported by the HAL. Removed functions chPutWouldBlock() and
chGetWouldBlock().
- CHANGE: Removed macro chMsgGetS(), chMsgGet() is still available.
- CHANGE: chprintf() now takes a BaseSequentialStream as parameter instead
of a BaseChannel making it more generic.
- CHANGE: Now the shell requires a BaseSequentialStream instead of a
BaseChannel for communications making it more generic.
- CHANGE: Kernel memory pools now do not check the alignment of the inserted
objects, it is responsibility of the application to insert properly
aligned objects.
- CHANGE: The PORT_INT_REQUIRED_STACK parameter for the Cortex-Mx ports has
been increased to 32 from 16 because the stack frame sizes are increased
when compiling with optimizations disabled, which is common during
debugging. In order to save RAM trim back this value when compiling with
optimizations enabled (backported to 2.4.1).
- CHANGE: Renamed Ethernet driver in AT91 HAL ETHD1 (backported to 2.4.1).
- CHANGE: Macros icuGetWidthI() and icuGetPeriodI() renamed to icuGetWidth()
and icuGetPeriod().

lwIP demos.
- NEW: lwIP related code is not centralized into a single place, no need to
duplicate the code in each application or demo.
- NEW: Updated the MSP port to work with the latest MSPGCC compiler (4.6.3
LTS 20120406 unpatched), now the old MSPGCC 3.2.3 is no more supported.
- CHANGE: The PORT_INT_REQUIRED_STACK parameter for the Cortex-Mx ports has
been increased to 32 from 16 because the stack frame sizes are increased
when compiling with optimizations disabled, which is common during
debugging. In order to save RAM trim back this value when compiling with
optimizations enabled.
- CHANGE: Renamed Ethernet driver in AT91 HAL ETHD1.
*** 2.4.0 ***
- NEW: Implemented new makefile system for ARM GCC ports, now objects,
listings and output files are generated into a "build" directory and not
together with sources, also implemented a simplified output log mode.
Now makefiles and load script files are requirements and trigger a
rebuild if touched.
- NEW: Improved Cortex-Mx port, now the Cortex-M4 are Cortex-M4F are also
supported. Improved startup files.
- NEW: Added a new hook THREAD_CONTEXT_SWITCH_HOOK() that allows to insert
code just before a context switch. For example this hook could be used
in oder to implement advanced power management schemes.
- NEW: Improved Event Flags subsystems in the kernel.
- NEW: Added a macro THD_STATE_NAMES to chthreads.h. This macro is an
initializer for string arrays containing thread state names.
- NEW: Added a new debug option CH_DBG_SYSTEM_STATE_CHECK that ensures the
correct API call protocol. If an API is invoked out of the correct context
then the kernel panics with a debug message.
- NEW: Added the new CMSIS 2.1 headers, now CMSIS resides into a shared
location: ./os/ports/common/ARMCMx/CMSIS. Old CMSIS files have been
removed from the various platforms.
- NEW: Removed all the ch.ld files from the ARMCMx demos, now the makefiles
point to common ld files under the various ports. Less duplication and
easier maintenance.
- NEW: Improved stack checking and reorganized memory map for the Cortex-Mx
demos. Now stacks are allocated at the start of the RAM, an overflow of the
exception stack now triggers an exception (it could go unnoticed before).
The process stack is organized to be checked on context switch like other
threads. Now all threads have an explicit stack boundary pointer.
- 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.
- NEW: Added initialization of the NVIC VTOR register to all Cortex-Mx (v7M)
ports. Also added a port option CORTEX_VTOR_INIT to enforce a different
default value into the register.
- NEW: Added "IRQ_STORM" test applications to those platforms supporting
ISR preemption.
- NEW: Added a chprintf() function to ./os/various, it can print on any
BaseChannel interface.
- NEW: Improved the mini shell, enhanced info command, optimizations and
removed the shellPrint() and shellPrintLine() functions, now it uses
chprintf() for output.
- NEW: USB driver model and USB implementation for STM32F1xx and STM32L1xx.
- NEW: USB CDC abstract driver.
- NEW: New driver models EXT, GPT, I2C, ICU, RTC, SDC, TM.
- NEW: Improved PWM and MAC driver models.
- NEW: Added support for STM32L1xx, STM32F2xx and STM32F4xx.
- NEW: Updated the STM32F1xx header file to the latest version 3.5.0 and fixed
it in order to correct several bugs related to the XL family.
- NEW: Added an unified registers file for STM32: stm32.h. This file includes
the appropriate vendor files then adds its own additional definitions.
- NEW: Added TIM8 support to the STM32 GPT, ICU and PWM drivers.
- NEW: DMA sharing in the STM32 HAL.
- NEW: ADC specific drivers for STM32L1xx, STM32F2xx and STM32F4xx.
- NEW: EXT driver AT91SAM7x and STM32(all).
- NEW: PAL driver for AVR.
- NEW: GPT driver for LPC11xx, LPC13xx and STM32(all).
- NEW: I2C driver for STM32(all).
- NEW: ICU driver for STM32(all).
- NEW: RTC driver for STM32F1xx.
- NEW: SDC driver for STM32F1xx.
- NEW: Added handling of USART6 to the STM32 serial driver.
- NEW: Added demos for the ST STM32F4-Discovery and STM32L1-Discovery kits.
- NEW: Updated AVR demos to use the new PAL driver.
- NEW: Now an error is generated at compile time when trying to enable the
options CH_DBG_ENABLE_STACK_CHECK on ports that do not support it.
- NEW: Added a kernel-only Cortex-Mx demo as reference project for users not
interested in the HAL but just want to use the ChibiOS/RT kernel.
The demo is named ARMCM3-GENERIC-KERNEL and is defaulted to the STM32, in
order to use it on other families or on the ARM Cortex-M0 just change the
inclusion paths in the makefile.
- NEW: Integrated new FatFs version 0.8b.
- NEW: lwIP 1.4.0 has been integrated, this new version does not require
custom hooks into the Thread structure and is thus much lighter.
- CHANGE: Now the callback associated to input queues is invoked before
reading each character. Previously it was invoked only before going
to sleep into the THD_STATE_WTQUEUE state.
- 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: Renamed the demo ARMCM3-STM32F107-GCC in ARMCM3-STM32F107 and added
IAR and Keil projects.
- CHANGE: Now the ARMCM3-STM32F107 demo targets the board Olimex STM32-P107
as default.
- CHANGE: Removed all the prefixes from the structure/union field names
in the HAL subsystem.
- CHANGE: Updated the documentation to use Doxygen 1.7.4 which produces a much
more readable output. Also modified the documentation layout to put functions
and variables ahead of everything else in the group pages.
Doxygen version below 1.7.4 cannot be used anymore because differences in
templates. Note that now there are two Doxygen projects, one for generating
the CHM file the other for plain HTML.
*** 2.2.8 ***

3411180).
*** 2.2.7 ***
- INFO: GCC test runs performed with YAGARTO 4.6.0.
- NEW: Added debug plugin for Eclipse under ./tools/eclipse.
- NEW: The debug macros chDbgCheck() and chDbgAssert() now can be externally
redefined. The macro chDbgCheck() no more includes the line number in the
description because incompatibility with the Cosmic compiler.
- NEW: Added a new functionality to the registry subsystem, now it is possible
to associate a name to the threads using chRegSetThreadName. The main and
idle threads have their name assigned by default.
- FIX: Fixed wrong check on CH_DBG_ENABLE_STACK_CHECK setting (bug 3387671).
- FIX: Fixed wrong APB1 frequency check (bug 3361039).
- FIX: Fixed missing state in shell demos (bug 3351556).

- 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.
- NEW: Added to the ARMv6-M sub-port an option to use the PendSV exception
instead of NMI for preemption.
*** 2.2.4 ***
- FIX: Fixed CodeBlocks demo broken (bug 3304718).
- FIX: Fixed race condition in output queues (bug 3303908).
- FIX: Fixed CH_USE_HEAP and CH_USE_MALLOC_HEAP conflict (bug 3303841).

- FIX: Fixed invalid BRR() macro in AVR serial driver (bug 3299306).
- FIX: Fixed missing IRQ vectors amicable names for STM32 XL devices (bug
3298889).
- FIX: Fixed wrong identifier in AVR serial driver (bug 3292084).
- FIX: Fixed wrong macro check for STM32 XL devices (bug 3291898).
- FIX: Fixed SPI driver restart in STM32 SPI driver implementation, also
applied the same fix to the STM8S SPI driver (bug 3288758).
- FIX: Fixed missing state transition in ADC driver (bug 3288149).
- FIX: Fixed missing state transition in SPI driver (bug 3288112).
- NEW: Added an option to the kernel to not spawn the Idle Thread from within
chSysInit(), this way the application can spawn a custom idle thread or
even use the main() thread as idle thread.
- 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.
*** 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).

- 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".

very critical context switch code (bug 3019738).
- FIX: Fixed insufficient stack space assigned to the idle thread in
Cortex-M3 port (bug 3019594).

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).

*** 1.2.0 ***
- 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).

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.
- FIX: Fixed wrong assertions in chThdWait() and chHeapFree().
