mazen Adel commented: https://gitlab.rtems.org/rtems/rtos/rtems/-/work_items/5633#note_156480 It should be noted that I was able to reuse only two algorithm-independent helper functions from the existing RTEMS Heap Handler: \_Heap_Align_down() and \_Heap_Align_up(). Reusing additional helpers was difficult for two main reasons. First, TLSF and first-fit use different blockdata and flags. TLSF stores an additional flag indicating whether the current block is used, However first-fit gets this information from the next block. Changing this is possible, but it would require modifications to the TLSF logic. I modified the TLSF block structure so that its physical layout matches the first-fit block structure when heap protection is disabled. However, I have not yet replaced Heap_Tlsf_Block with Heap_Block. If the remaining metadata and header differences are handled, TLSF could reuse at least three additional helpers: * \_Heap_Block_at() instead of \_Heap_Tlsf_Block_at(). * \_Heap_Prev_block() instead of \_Heap_Tlsf_Block_prev(). * \_Heap_Alloc_area_of_block() instead of \_Heap_Tlsf_Block_to_ptr(). -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/work_items/5633#note_156480 You're receiving this email because of your account on gitlab.rtems.org.
