Add debugging capability to profile ion alloc, smmu map and unmap calls. Enable below debugfs settings to get the traces with corresponding latencies. Alloc : echo 1 > /sys/kernel/debug/camera_memmgr/alloc_profile_enable Map, Unmap : echo 1 > /sys/kernel/debug/camera_smmu/map_profile_enable Capture the profiling numbers in traces.
