1) What is the reason here?
Hello rakesh_patel,
The firmware missing message is a bit misleading. The SDMA unit has a ROM firmware which can be patches if you install a separate firmware.
Regards.
In kernel 4.1.15, there was directory kernel-source/firmware but there is no kernel-source/firmware directory in latest kernel 5.4
