The calculation of fl index max is changed to always be the smallest
number that includes the size of the registered memory.
The control_construct() function now checks for minimum size as the control structure
parameters are calculated.
There is no longer a minimum configuration for fl index max so the tlsf_config
enum is striped down to remove unecessary compile time values.
the tlsf_size() function will fail if no tlsf pointer is passed as parameter since there
is no way to calculate a default tlsf size anymore.
bitfields are now used in control_t when possible which reduces the size of the structure
from 56 bytes to 36 bytes.
This commit extends the heap test set by adding a test to check corruption
detection in free memory block.
For each byte of the free block memory, the test changes the value of the byte,
call multi_heap_check(), make sure that the function returns 'corruption detected'
only when comprehensive poisoning is set, restore the good value of the byte, calls
multi_heap_check() again and make sure that it returns 'OK'.
Add a call to tlsf_check_hook() in tlsf_check() that calls
multi_heap_internal_check_block_poisoning() and check the memory
of every free blocks when heap poisoning is active.
Don't call heap_caps_alloc_failed() for malloc(0) and calloc(0), because it is not an error.
Improve handling of malloc(0) and calloc(0).
Merges https://github.com/espressif/esp-idf/pull/9517
heap_caps_*_prefer functions will now only call heaps_caps_alloc_failed
callback if all attempts to allocation memory fail (and not after each attempt
anymore).
* Closes https://github.com/espressif/esp-idf/issues/9086
Fix a bug that could return a chunk of memory smaller than requested,
easily leading to a memory corruption, when the required memory alignment
passed to the allocator is 4.
Add TRY_ENTRY_CRITICAL() API to all for timeouts when entering critical sections.
The following port API were added:
- portTRY_ENTER_CRITICAL()
- portTRY_ENTER_CRITICAL_ISR()
- portTRY_ENTER_CRITICAL_SAFE()
Deprecated legacy spinlock API in favor of spinlock.h. The following API were deprecated:
- vPortCPUInitializeMutex()
- vPortCPUAcquireMutex()
- vPortCPUAcquireMutexTimeout()
- vPortCPUReleaseMutex()
Other Changes:
- Added portMUX_INITIALIZE() to replace vPortCPUInitializeMutex()
- The assembly of the critical section functions ends up being about 50 instructions longer,
thus the spinlock test pass threshold had to be increased to account for the extra runtime.
Closes https://github.com/espressif/esp-idf/issues/5301
