config DEBUG_HEAP bool "Heap debug" default n help Select for enable heap alloc debugging config DEBUG_BLOCK_FREE bool "Blocks freeing debug" default n help It enables checking if free was called multiple times on already freed block of memory. Enabling this feature increases number of memory writes and reads, due to checks for memory patterns that may be performed on allocation and deallocation. config DEBUG_FORCE_COHERENT_BUFFER bool "Force the allocator to allocate coherent buffer only" default n help Select if we want to force the allocator to return coherent/uncached buffer only. This should be selected for debug purpose only, as accessing buffer without caching it will reduce the read/write performance.
