Adds CONFIG_SPIRAM_ENC_EXEMPT, available on chips that support per-page
PSRAM encryption configuration (esp32c5, esp32c61, esp32p4). When
enabled, esp_psram carves CONFIG_SPIRAM_ENC_EXEMPT_SIZE off the top of
PSRAM and maps it via the new mmu_hal_map_region_no_enc() helper, which
writes MMU entries without the SENSITIVE bit. The region is registered
as a separate heap pool reachable only through the new
MALLOC_CAP_SPIRAM_NO_ENC capability bit, so default SPIRAM allocations
cannot accidentally land there.
PSRAM encryption imposes alignment constraints that some DMA engines
(e.g. 2D-DMA) cannot satisfy. This option lets such workloads place
their buffers in unencrypted PSRAM while keeping the rest of PSRAM
(and flash) encrypted. Default disabled; security implications are
documented in the Kconfig help text.
After startup is done and app_main is reached, all calls to
heap_caps_add_region_with_caps (adding a new heap to the list of registered
heaps) will not affect the minimum free heap size value.
For heaps created before startup, this won't apply and their size will
end up being taken into account in the calculation of the minimum.
feat(esp32h21): added support for misc core system features
Closes IDF-12042, IDF-11598, IDF-11596, IDF-11874, IDF-11873, IDF-11528, and IDF-11511
See merge request espressif/esp-idf!38773
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.
esp_ptr_in_rtc_iram_fast logic should be executed if
SOC_RTC_FAST_MEM_SUPPORTED is set but it should also be executed
if IRAM and DRAM region mapping is the same. Remove the
SOC_RTC_IRAM_LOW != SOC_RTC_DRAM_LOW part of the check.
Update heap component to use the modify function appropriately.
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.
