This commit removes the following critical nested macros as follows:
- portENTER_CRITICAL_NESTED()
- portEXIT_CRITICAL_NESTED()
They are replaced with portSET_INTERRUPT_MASK_FROM_ISR() and
portCLEAR_INTERRUPT_MASK_FROM_ISR() which are the proper FreeRTOS interfaces.
Created a portmacro_deprecated.h for each port to contain deprecated API
that were originally from portmacro.h
This commit adds the following hook functions to obtain memory
for the IDLE and Timer Daemon tasks when configSUPPORT_STATIC_ALLOCATION
is enabled:
- vApplicationGetIdleTaskMemory()
- vApplicationGetTimerTaskMemory()
Currently, both functions simply allocate from the same memory as
regular tasks (i.e., internal memory for both the stack and TCB)
Closes https://github.com/espressif/esp-idf/issues/7511
Noted as a problem with thread local storage returning a different task's
pointers, but some other were APIs also accessing current task unsafely.
Regression in FreeRTOS 10 update a3c90bf59a
Causes test added in parent commit to pass.
This race happens if the deleted task is running on the other CPU,
and is already spinning in a critical section waiting for xTaskQueueMutex
because it's about to be blocked for a resource.
The "deleted" task would end up blocked, possibly indefinitely, and
never actually deleted or its resources cleaned up by the idle tasks.
Details:
vTaskDelete() adds the target task to the xTasksWaitingTermination list,
expecting it to be yielded off CPU and then cleaned up later. However as soon as
vTaskDelete() releases xTaskQueueMutex, the target task runs and moves itself to the
xDelayedTaskList1. Because interrupts are already disabled on that CPU,
the "yield" to the other CPU sent by the vTaskDelete() comes afterward so
doesn't help.
Removed leftover code-paths that were never taken. Upstream freertos uses
vTaskSuspendAll() and xTaskResumeAll(), and therefor check if the task already
yielded.
In the IDF port of freertos we use critcal sections instead, so xAlreadyYielded
will never be set.
Partially addresses https://github.com/espressif/esp-idf/issues/6440
freertos: replace the freertos regular malloc to the specific malloc from xtensa port for tcb and stack allocations
freertos: avoid the cpu1 to unwind pended ticks when xTaskResumeAll is called insed of an ISR
freertos: protected the xPortGetCoreID functions with missing critical sections
tests: re-eanble the ignored tests that was failling before race-condition fixes
freertos/port: update the port files and split into xtensa and riscv ports
freertos: separated cpu files from rest of the kernel sources
freertos/port_xtensa: separated private include files into a folder
freertos/tasks: added task create pinned to core function do not break current IDF API
freertos/tasks: mimiced task create pinned function into tasks.c to do not break the IDF API.
freertos: freertos component now compiling
freertos: freertos component now building
freertos: moved critical sections outside from FR kernel section to portable section
portmacro_xtensa: add void indentifier on functions that take no arguments
freertos: fix critical sections implementation to match with their function prototype
freertos: add cmake changes of freertos into make
freertos: remove portDONT_DISCARD attribute from switch context function, it was breaking the docs building.
freertos: fix conflicitng types of vApplicationSleep function
license: update the license of freertos
freertos: Doxygen comments refactored to render them correctly on docs
freertos: added new functions of freertos into the documentation
freertos: added message buffers and stream buffers to documentation
sysview: update freertos system view to the compatible with version 10
freertos: fixed event group documentation rendering
freertos: update static task structure to match the actual tcb size
freertos: removed backported test functions
freertos/smp: brought SMP code to FreeRTOS 10 port
freertos/portmacro: added missing crosscore interrupt for yielding tasks
freertos: replaced soft-critical sections with hard-critical sections used by SMP
freertos: placed muxes inside of kernel objects
freertos: replaced original FR critical sections with SMP enabled spinlocks critical sections
freertos: moved xtensa port files to a separated folder
freertos: added multiple instance of global variables required to SMP
freertos: added SMP modifications on specific tasks module functions
freertos: added TLS deletion function to task module
freertos/tls: initialize TLS deletion callback to avoid crashing when calling task delete
freertos: modified vTaskDelete to do not erase current task that runs on other core
freertos: reverted taskhandle and timerhandle as void* type
freertos: fixed de-referencing void pointer to get run time counter
freertos: fix system view trace enter macro arguments
freertos: Replaced soft critical sections with spinlocks on event_groups
freertos: fixed tick function to avoid calling tick hooks twice
freertos: Nofity give checking per CPU if schedule is suspended
freertos: added mpu release on TCB deletion
freertos: Added SMP changes when deleting a TCB on idle task
freertos/license: update freertos license in COPYRIGHT.rst
freertos: unicore configurations can use task create pinned to core, it will be always pinned to core 0
freertos/portmacro: added cpu_hal_get_core_id() function instead of inline assembly
freertos/xtensa: update xtensa specific files used in master branch
newlib/locks: revert the preemption checking in lock acquisition and release
ref_clock: fix initial state of ref_clock interrupt handler
freertos: added missing critical sections and yielding checkings
freertos: remove magic numbers in vTaskDelete
freertos: added missing critical section in prvIsQueueEmpty
spin_lock: cleaned-up port files and removed portmux files
components/soc: decoupled compare and set operations from FreeRTOS
soc/spinlock: filled initial implementation of spinlock refactor
It will decouple the spinlocks into separated components with not depencences of freertos
an similar interface was provided focusing the readabillity and maintenance, also
naming to spinlocks were adopted. On FreeRTOS side the legacy portMUX macros
gained a form of wrapper functions that calls the spinlocks component thus
minimizing the impact on RTOS side.
This feature aims to close IDF-967
soc/spinlock: spinlocks passed on unit test, missing test corner cases
components/compare_set: added better function namings plus minor performance optimization on spinlocks
soc/spinlock: code reordering to remove ISC C90 mix error
freertos/portmacro: gor rid of critical sections multiline macros, placed inline functions instead
soc/spinlock: improved spinlock performance from internal RAM
For cases where the spinlock is executed from IRAM, there is no
need to check where the spinlock object is placed on memory,
removing this checks caused a great improvement on performance.
components/freertos: cleaned up multicore option scheduler.
components/freertos: more cleanup and test optimization to present realistic results
components/freertos: remove unused macros of optimized task selection when multicore is used
