Previously, TLSP deletion callbacks were...
- Stored in a seprate TCB member "pvThreadLocalStoragePointersDelCallback"
- Called separately via multipole prvDeleteTLS() insertions in tasks.c
This commit refactors how TLSP deletion callbacks are stored and called:
- TLSP deletion callbacks are now stored in "pvThreadLocalStoragePointers"
directly. configNUM_THREAD_LOCAL_STORAGE_POINTERS is doubled in size so that
the deletion callbacks are stored in the latter half of the array
- The callbacks are now called via "portCLEAN_UP_TCB()". As such, the
prvDeleteTLS() additions are no longer needed and the function can be removed
- Removed some legacy TLSP tests using the old method of storing the callback
pointers.
This commit reduces the source code diff between IDF FreeRTOS and upstream
vanilla FreeRTOS, in preparation for v10.5.1 upgrade.
portCLEAN_UP_COPROC() was an IDF specific addition to FreeRTOS, where the
macro was called from prvDeleteTCB() to clean up the coprocessor context of a
deleted task.
This commit removes portCLEAN_UP_COPROC(). The coprocessor cleanup routine
(i.e., vPortCleanUpCoprocArea()) is now called via portCLEAN_UP_TCB()->
vPortTCBPreDeleteHook().
This removes a minor code difference between IDF FreeRTOS and upstream.
Previously, if CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP was enabled, users
would provide a definition for a vPortCleanUpTCB() hook function that is called
right before a task's memory is freed in prvDeleteTCB(). However,
vPortCleanUpTCB() will be reclaimed by ESP-IDF for internal use in v6.0.
This commit introduces the following changes...
Introduced a new CONFIG_FREERTOS_TASK_PRE_DELETION_HOOK option:
- Provides the same pre-deletion hook functionality. But users now define
vTaskPreDeletionHook() instead.
- CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP still exists, but is marked as
deprecated. This is to maintain compatibility with existing applications
that already define vPortCleanUpTCB().
- Removed redundant --wl --wrap workaround with vPortCleanUpTCB()
- Added todo notes to remove support for user defined vPortCleanUpTCB()
completely in v6.0.
- Updated test cases to use new CONFIG_FREERTOS_TASK_PRE_DELETION_HOOK option
Freed up portCLEAN_UP_TCB() to call a new internal vPortTCBPreDeleteHook():
- vPortTCBPreDeleteHook() now replaces the previous "wrapped" implementation
of vPortCleanUpTCB().
- vPortTCBPreDeleteHook() is an internal task pre-delete hook for IDF FreeRTOS
ports to inject some pre-deletion operations.
- Internal pre-delete hook now invokes user provided vTaskPreDeletionHook()
if enabled.
- Relocated vPortTCBPreDeleteHook() to correct section in port.c
The default zero input gpio num is 0. Users need to set it additionally
when not use zero input signal. It may become a breaking change.
Add an enable flag to avoid it.
1: reset p_scb->avdt_handle in cleanup function.
2: cancel comparing p_scb->codec_type and p_scb->seps[xx].codec_type to
send the error INVALID_CODEC_TYPE.
