[PATCH 00/15] *** Multiple level VMPT enablement ***

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi David,

changes to patches #8 and #10 look good to me, but Alex (or somebody 
else? Jerry?) should acknowledge these at least as well.

Patch #11 is Reviewed-by: Christian König <christian.koenig at amd.com>.

Patch #12 we need to clean this up a bit more, otherwise we will run 
into issue with mixed APUs+Vega10 systems (or even Vega10+older dGPU).

Going to take care of this, but for now the patch is Reviewed-by: 
Christian König <christian.koenig at amd.com>.

Patch #13, dito this needs cleanup. But for now Reviewed-by: Christian 
König <christian.koenig at amd.com>.

All other patches are either from me or already reviewed. I would say 
wait till tomorrow for additional comments and then feel free to commit 
to amd-staging-4.9.

Regards,
Christian.
