- the control_t structure should not be available to the user so it
was moved to tlsf.c. In addition bitfields are now used in control_t
when possible which reduces the size of the structure from 56 bytes
to 36 bytes.
- fix an assert message to place it in the tlsf_assert
- add comment about the index count log2 field in control_t
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.
Note: block_absorb() is called in tlsf_free(), which is eventually called in multi_heap_free()
after the memory fill is done. As the block_absorb merges 2 blocks together, the previous block
header of the merged block is now in the middle of the memory block but not filled with 0xfe.
- Remove dependencies with the heap component of the IDF.
- The tlsf_poison_fill_region_hook() function is defined as weak in IDF and checked for NULL
in block_absorb() function in order to minimize the dependencies between IDF and the TLSF.
- The the implementation of tlsf_poison_fill_region_hook() must be provided at the discretion
of the user.
