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outdated implementation in the ROM.
In order to enable CONFIG_HEAP_TASK_TRACKING, some kind
of poisoning had to be enabled (!HEAP_POISONING_DISABLED).
However since those functionalities don't seem to be related
in any way, this commit decouple them by removing
MULTI_HEAP_BLOCK_OWNER from poison_head_t in multi_heap_poisoning.c
and handling the block ownership in heap_caps.c instead.
Note that handling task tracking in multi_heap.c would necessitate
updating the ROM implementation of multi_heap.c as well. For this
reason, the task tracking feature has to be handled in heap_caps.c.
- 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.
- and place all added functions and vairables related to the hashmap in RAM
when the config is enabled only.
- add number of hash map entry as a Kconfig value and remove the hash map init function.
This prevents the user from allocating the hash map in flash and pass the pointer to the
init function (as the heap trace manipulate the hash map from functions placed in IRAM).
- add max linear value to the KConfig to make it configurable by the users.
- protect access to static variable "tracing"
- remove unecessary field in heap_trace_hashmap_entry_t
Add back a feature that was available in the old heap implementation
in release/v2.1 and earlier: keep track of which task allocates each
block from the heap. The task handle is conditionally added as
another word in the heap poisoning header under this configuration
option CONFIG_HEAP_TASK_TRACKING.
To allow custom monitoring and debugging code to be added, add helper
functions in multi_heap.c and multi_heap_poisoning.c to provide access
to information in the block headers.
Add esp_heap_debug_dump_totals() to monitor heap usage
esp_heap_debug_dump_totals() dumps into a user-provided data structure
a summary of the amound of heap memory in region type that is used by
each task. Optionally it will also dump into another data structure
the metadata about each allocated block for a given list of tasks or
for all tasks (limited by available space).
Address change requests on PR #1498
This set of changes fixes the files in e3b702c to just add the
CONFIG_HEAP_TASK_TRACKING option without adding the new function
heap_caps_get_per_task_info() in case that is the only portion of the
PR that will be accepted. Part of the change is to remove the new .c
and .h files containing that function and to remove the line to
compile it from components/heap/component.mk since it should not have
been included in e3b702c. One or more additional commits to add the
new function will follow.
The other changes here:
- uint32_t get_all_caps() moves to heap_private.h
- replace "void* foo" with "void *foo"
- add braces around single-line "if" blocks
- replace tab characters with spaces
Address change requests on PR #1498, part 2
This set of changes fixes the files in cdf32aa to add the new function
heap_caps_get_per_task_info() with its new name and to add the line to
compile it in components/heap/component.mk. This does not address all
the suggested changes because there are some needing further
discussion.
This commit does not include the suggested change to move the
declaration of the new function into esp_heap_caps.h because the new
function references TaskHandle_t so esp_heap_caps.h would have to
include freertos/FreeRTOS.h and freertos/task.h, but FreeRTOS.h
includes esp_heap_caps.h through two other header files which results
in compilation errors because not all of FreeRTOS.h has been read yet.
Change heap_caps_get_per_task_info() to take struct of params
In addition to moving the large number of function parameters into a
struct as the single parameter, the following changes were made:
- Clear out the totals for any prepopulated tasks so the app code
doesn't have to do it.
- Rather than partitioning the per-task totals into a predetermined
set of heap capabilities, take a list of <caps,mask> pairs to
compare the caps to the heap capabilities as masked. This lets the
caller configure the desired partitioning, or none.
- Allow the totals array pointer or the blocks array pointer to be
NULL to indicate not to collect that part of the information.
- In addition to returning the total space allocated by each task,
return the number of blocks allocated by each task.
- Don't need to return the heap capabilities as part of the details
for each block since the heap region (and therefore its
capabilities) can be determined from the block address.
- Renamed heap_task_info.h to esp_heap_task_info.h to fit the naming
convention, and renamed the structs for totals and block details to
better fit the revised function name.
- Provide full Doxygen commenting for the function and parameter
structs.
