This has two consequences: 1) The value is recalculated once 2) it is possible to use the new API chVTGetCurrentDelta() and update the static setting in order to avoid recalculation. - NEW: OSLIB release methods now return the value of the reference counter. - NEW: Support for STM32C0xx. - NEW: Improved DAC driver, updated STM32 DACv1. - NEW: STM32 RTCv2 and RTCv3 modified to not use shadow registers. - NEW: Enhanced STM32F7xx MPU configuration in mcuconf.h. - NEW: I2C slave support in HAL high level driver. - NEW: Added settings for STM32 OCTOSPIv1 and OCTOSPIv2 TCR bits SSHIFT and DHQC. - NEW: Automatic removal of duplicated inclusion paths on make command lines. - NEW: Reworked STM32 SDMMCv1 and SDMMCv2 drivers, better timeout and clock handling, improved speed for aligned buffers. - NEW: Added a "waend" field to the thread structure in RT for debug convenience. - NEW: Added a para-virtualized HAL port for use in sandboxes. - NEW: Added a VIO subsystem to sandboxes supporting drivers para-virtualization, PAL and SIO supported so far. - NEW: Added and RT port for use in virtualized sandboxes. - NEW: Added full virtualization support to sandboxes with a virtual IRQ mechanism. - NEW: Added __CH_OWNEROF() macro to RT. - NEW: Added a Posix-favored shell named "msh" (Mini Shell). The shell is able to run sub-apps inside the same sandbox. The shell can either be placed statically in flash or loaded dynamically in RAM. - NEW: Added runnable "apps" capability to SBs, apps available so far: msh, ls. - NEW: Added ability to load ELF files to SBs. - NEW: Enhanced Posix API for SBs leveraging the VFS integration. - NEW: SBs and VFS integration. Each SB can see its own VFS instance. - NEW: Added integration of LittleFS on top of our flash infrastructure. - NEW: Added a new MEM_IS_VALID_FUNCTION() macro to RT and NIL. - NEW: Changed SB configuration options names to be prefixed with SB_CFG_. - NEW: Added a new CH_CFG_HARDENING_LEVEL option to RT. - NEW: Added a chXXXDispose() function to all objects in NIL. - NEW: Added a chXXXDispose() function to all objects in RT. - NEW: Added VFS-related commands to the shell, disabled by default. - NEW: Added a new VFS subsystem (Virtual File System), it allows to assemble trees of files from multiple "File System Drivers" into a single tree and access it as a whole. - NEW: Added MEM_NATURAL_ALIGN macro to RT and NIL. - NEW: Added static initializer for virtual timers in RT. - NEW: Added new function chHeapIntegrityCheck(). - NEW: Function chCoreGetStatusX() changed to return a memory region object instead of a simple size. - NEW: RT and NIL upgraded to support the enhanced OSLIB. - NEW: Memory areas/pointers checker functions added to OSLIB. - FIX: Fixed problem in recursive locks functions (bug #1288) (backported to 20.3.5)(backported to 21.11.4). -
