Looks like you are using 5.13 kernel for this work, FYI we added
hot plug support for the graphic stack in 5.14 kernel (see
https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.14-AMDGPU-Hot-Unplug)
I am not sure about the code part since it all touches KFD driver (KFD
team can comment on that) - but I was just wondering if you try 5.14
kernel would things just work for you out of the box ?
