Changelog Multicore Manager#

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[v5.0.2]#

Added#

  • Added gcov options and configs to support mcmgr code coverage

  • Added new test_weak_mu_isr testcase for devices with MU peripheral

  • Added new test_heartbeat testcase showing heartbeat mechanism between primary and secondary cores using the MCMGR

v5.0.1#

Added#

  • Added frdmimxrt1186 unit testing

Changed#

  • [KW43] Rename core#1 reset control register

Fixed#

  • Added CX flag into CMakeLists.txt to allow c++ build compatibility.

  • Fix path to mcmgr headers directory in doxyfile

v5.0.0#

Added#

  • Added MCMGR_BUSY_POLL_COUNT macro to prevent infinite polling loops in MCMGR operations.

  • Implemented timeout mechanism for all polling loops in MCMGR code.

  • Added support to handle more then two cores. Breaking API change by adding parameter coreNum specifying core number in functions bellow.

    • MCMGR_GetStartupData(uint32_t *startupData, mcmgr_core_t coreNum)

    • MCMGR_TriggerEvent(mcmgr_event_type_t type, uint16_t eventData, mcmgr_core_t coreNum)

    • MCMGR_TriggerEventForce(mcmgr_event_type_t type, uint16_t eventData, mcmgr_core_t coreNum)

    • typedef void (*mcmgr_event_callback_t)(uint16_t data, void *context, mcmgr_core_t coreNum);

    When registering the event with function MCMGR_RegisterEvent() user now needs to provide callbackData pointer to array of elements per every core in system (see README.md for example).In case of systems with only two cores the coreNum in callback can be ignored as events can arrive only from one core. Please see Porting guide for more details: PortingGuideTo_v5.md

  • Updated all porting files to support new MCMGR API.

  • Added new platform specific include file mcmgr_platform.h. It will contain common platform specific macros that can be then used in mcmgr and application. e.g. platform core count MCMGR_CORECOUNT 4.

  • Move all header files to new inc directory.

  • Added new platform-specific include files inc/platform/<platform_name>/mcmgr_platform.h.

Added#

  • Add MCXL20 porting layer and unit testing

v4.1.7#

Fixed#

  • mcmgr_stop_core_internal() function now returns kStatus_MCMGR_NotImplemented status code instead of kStatus_MCMGR_Success when device does not support stop of secondary core. Ports affected: kw32w1, kw45b41, kw45b42, mcxw716, mcxw727.

[v4.1.6]#

Added#

  • Multicore Manager moved to standalone repository.

  • Add porting layers for imxrt700, mcmxw727, kw47b42.

  • New MCMGR_ProcessDeferredRxIsr() API added.

[v4.1.5]#

Added#

  • Add notification into MCMGR_EarlyInit and mcmgr_early_init_internal functions to avoid using uninitialized data in their implementations.

[v4.1.4]#

Fixed#

  • Avoid calling tx isr callbacks when respective Messaging Unit Transmit Interrupt Enable flag is not set in the CR/TCR register.

  • Messaging Unit RX and status registers are cleared after the initialization.

[v4.1.3]#

Added#

  • Add porting layers for imxrt1180.

Fixed#

  • mu_isr() updated to avoid calling tx isr callbacks when respective Transmit Interrupt Enable flag is not set in the CR/TCR register.

  • mcmgr_mu_internal.c code adaptation to new supported SoCs.

[v4.1.2]#

Fixed#

  • Update mcmgr_stop_core_internal() implementations to set core state to kMCMGR_ResetCoreState.

[v4.1.0]#

Fixed#

  • Code adjustments to address MISRA C-2012 Rules

[v4.0.3]#

Fixed#

  • Documentation updated to describe handshaking in a graphic form.

  • Minor code adjustments based on static analysis tool findings

[v4.0.2]#

Fixed#

  • Align porting layers to the updated MCUXpressoSDK feature files.
