2.2.x stable branch

[Giovanni]

Hello,

I branched the 2.2.0 version from the version 2.1.8 currently in the trunk, most reports have been regenerated and it seems everything is ok. The plan is to release it Saturday 29, please report any problem you may be aware of before then, there is still time for last minute fixes.

• PDF and CHM, ads-free, documents. The downloads are available from here for a small fee.
• Self-built documentation from source without ads.

This new release brings many new features and improvements, this is the synthetic list:

Code: Select all

Hello,

ChibiOS/RT 2.2.2 has been released. This maintenance release fixes all the known bugs (one rather important related to the Cortex-M0) and also introduces some improvements back-ported from the trunk version.

Code: Select all

*** 2.2.2 ***
- FIX: Fixed race condition in CM0 ports, the fix also improves the
  ISR latency (bug 3193062).
- FIX: Fixed Cortex-Mx linker scripts alignment of __heap_base__, the
  correct alignment is now enforced at runtime into core_init() in order
  to make the OS integration easier (bug 3191112).
- FIX: Fixed error in function chCoreAllocI() function documentation (bug
  3191107).
- FIX: Fixed minor problem with memory pools (bug 3190512).
- NEW: Added I-Class functions to the MailBoxes subsystem, now it is
  possible to use them as a transport layer between ISRs and Threads.
- CHANGE: Swapped the numeric values of the TIME_IMMEDIATE and TIME_INFINITE
  constants. Fixed the relative documentation in various places.
- Documentation related fixes.

Hi,

ChibiOS/RT 2.2.3 has been released. This maintenance release fixes an important bug related to the I/O queues and all the other known minor bugs. Minor new features and improvements have been added.

This is a recommended update.

Code: Select all

*** 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.

Hi,

ChibiOS/RT 2.2.4 has been released. This maintenance release fixes an important bug related to the I/O queues and all the other known minor bugs. Minor new features and improvements have been added, 30% performance improvement in I/O queues.
This is a recommended update.

Code: Select all

*** 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 timeout problem in the lwIP interface layer (bug 3302420).
- 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.

Hi,

ChibiOS/RT 2.2.5 has been released. This version fixes a small bug and introduces performance and functional improvements to the Cortex-Mx ports backported from version 2.3.4.

Code: Select all

*** 2.2.5 ***
- FIX: Fixed STM32F107 demo build failure (bug 3294998).
- 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.

Hi,

ChibiOS/RT 2.2.7 has been released. This release fixes few minor bugs but also introduces kernel enhancements related to debugging. An RTOS-aware plugin for Eclipse is now included.

Code: Select all

*** 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).
- CHANGE: Removed todo.txt file, it does not belong to the stable version.


FYI, the current plan is to maintain the stable branch 2.2.x at least through 2011 and 2012.
