The new TLSF architecture has changed. tlsf.h public API
header is now moved into an include folder. tlsf_common.h
is removed from the repo.
This commit updates the heap component and respective
esp_rom patches to take into account this new
architecture.
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.
This commit adds a feature to pause the heap tracing in the
sense that in this state, the heap tracing will no longer
record the new allocations but will continue to monitor
the free() in order to keep track of the status of the
allocations present in the list of records.
See https://github.com/espressif/esp-idf/issues/13803
Add a test to make sure that the task handles returned in the
task tracking information are valid task handles.
To verify that, feed the task name returned by pcTaskGetName()
using the task handle under test to xTaskGetHandle() and make
sure the task handle returned matches the one under test.
This return value is used by the tlsf_walk_pool
function to be notified of the need to interrupt
the ongoing traversal of the currently traversed
heap.
Introduce new APIs in essp_heap_caps.h:
- heap_caps_walk()
- heap_caps_walk_all()
Those functions are triggering a callback for all blocks
(allocated or free) of memory present in heaps meeting
the set of capabilities passed as parameter (or all heaps
for heap_caps_walk_all() function)
test_walker.c added to test the new functionality in
test_apps/heap_test/
Implement a function to start tracking the minimum free size from the
moment the function is called.
Implement a function to stop tracking the minimum free size and restore
the minimum free size value calculated since startup.
Implement the tests related to this new feature.
- Add sdkconfig.ci.task_tracking that runs generic tests
with heap task tracking enabled.
- Add task_tracking.c that includes a test checking that
a created task that allocates memory is added to the list
of task tracked by the heap task tracking feature.
The integrity_walker now calls the integrity check hook to control
free AND used blocks of memory in the TLSF pool. This integrity walker
function is called from tlsf_check_pool.
This commit creates a patch of integrity_walker function to update the
outdated implementation in the ROM.
Previously, the hash map was a doubly linked list but was never
using the characteristics of it.
This commit switches the hash map to a singly linked list instead
This commit also fixes memory leak in heap trace tests by setting
hashmap size to 10 for the tests (instead of the default value of 250)
See https://github.com/espressif/esp-idf/issues/11173
This commit updates the tlsf submodule to include the modification made in the component
aiming to perform integrity check on all blocks (not only the free ones).
Added test to test the fix in test_apps/heap_tests.
Fixes https://github.com/espressif/esp-idf/issues/12231
- Remove the size limit for the hash_map array from the CONFIG_HEAP_TRACE_HASH_MAP_SIZE
- Add test case for heap tracing using hashmap
- Update heap_debug.rst to document the newly added configurations in the heap component
Closes https://github.com/espressif/esp-idf/issues/11172
Add test configuration to run all tests with heap component in the flash.
Add reference to this new configuration in performance section of the documentation.
- Fix "test get allocated size"
- Add tests for the free / alloc hooks
- Call alloc function hook on malloc/realloc/calloc base functions
- Add caps parameter to the allocation hook function
After heap_idf.c has been added (where the FreeRTOS heap is a subset of the
ESP-IDF heap), xPortGetFreeHeapSize() was updated to only returns the free
size of the FreeRTOS heap and not the entire ESP-IDF heap.
This commit replaces calls of xPortGetFreeHeapSize() with
esp_get_free_heap_size() in places outside of FreeRTOS.
