Subject: Re: [PATCH 3/3] drm/amdkfd: Remove the control stack workaround for
GFX10
Yes. I confirmed with CP guys and they said the behavior on GFX10 is the
same as GFX8 now. I remember that the workaround on GFX9 was to help
with a HW bug, but not too sure.

I wouldn't call this a bug and a workaround. More like a change in the
HW or FW behaviour and a corresponding driver change. I.e. in GFXv8 the
control stack was in the user mode CWSR al
The GFX10 does not have this hardware bug any more, so remove it.
