Part Number: AM5726
continuing the discussion from the attached thread.. (https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1206364/am5726-cma_alloc-failed)
this problem started happening on the new kernel v4.19.94-139944
we have the DEBUGFS enabled now for CMA, but we cant seem to resolve this in any way.
we tried using echo N > /sys/kernel/debug/cma/cma-dsp2_cma@9a/free
where N = 20480 (read it from count)
below is the output of the dmesg
dmesg | grep -i cma
