What RDK is this ? I don't see such an API in DVR RDK. Anyhow alloc and free should take insignificant time essentially. Utils_memAlloc does memset of the allocated memory if
gUtils_memClearBuf[<heap_id>] is set to TRUE (by default it is set to TRUE).
First try setting it to FALSE in
/dvr_rdk/mcfw/src_bios6/utils/src/utils_mem.c
Int32 Utils_memClearOnAlloc(Bool enable)
{
UInt32 i;
for (i=0; i<UTILS_MEM_NUM_SHARED_REGION_HEAP; i++)
{
gUtils_memClearBuf[i] = FALSE;
}
return 0;
}
This will confirm if the time taken is due to clearing memory. Even so Utils_memFree will not take any time unless some Cache operation is done on the freed memory.
If you still see large time even after disabling memory clear it means alloc/free is itself taking lot of time which can happen only if there is contention for the GateMP lock when trying to allocate or free memory.
