Yes, I would like to implement queue reset for all SDMA versions and I would 
like to extend this function to do that.

My main motivation for this is that we want to enable SDMA for older GPU 
generations in RADV. The SDMA will see more use, and therefore the kernel 
needs to handle when the SDMA hangs.

I already have a prototype implementation of the queue reset for SDMA v2 (CIK) 
which makes is much easier to develop the SDMA code in RADV because it can 
recover from hangs without needing me to reboot my computer as I am developing 
and testing the code in RADV.

Thanks & best regards,
