This feature keeps track of the per task peak memory usage.
- Update the heap_task_tracking example to make use of the new feature
Cleanup the implementation:
- multi_heap_get_free_size() is never used, remove it.
- Minor update in heap_caps_update_per_task_info_xx() funcitons.
- Update settting on block owner in heap_caps.c to work with the
get peak usage feature.
- Update heap_caps_update_per_task_info_free() to detect when it
is called to delete the memory allocated for a task TCB. Mark
the corresponding task in the statistic list as deleted.
- Add a Kconfig option dependant on HEAP_TASK_TRACKING being enabled
that force the deletion of the statistics related to deleted task
when set to true.
- In task tracking feature, add a current and peak memory usage
to the heap_stat_t structure to keep track of the current and
peak memory usage of the given task across all heaps.
- Fix missing block owner when allocating memory for heaps_array
in heap_caps_init.
- Keep the original implementation of the task tracking
for backward compatibility reasons.
This commit fixes the issue when trying to allocate memory
with the MALLOC_CAP_EXEC in RTC memory. Prior to the fix,
the heap allocator was returning an address in RTC DRAM.
To fix this issue:
- modified memory_layout.c of the concerned targets to fill the iram_address
field in the rtc entry of the soc_memory_region array properly.
- modified heap component related functions to return IRAM address when
an allocation in RTC memory with MALLOC_CAP_EXEC is requested.
Closes https://github.com/espressif/esp-idf/issues/14835
The implicit promise of heap_alloc_caps() and friends is that the memory it
returns is fit for the purpose as requested in the caps field. Before
this commit, that did not happen; e.g. DMA-capable memory wass returned
from a correct region, but not aligned/sized to something the DMA subsystem
can handle.
This commit adds an API to the esp_mm component that is then used by the
heap component to adjust allocation alignment, caps and size dependent on
the hardware requirement of the requested allocation caps.
