Hi all,
Here is a series to enable perf support on Cannonlake. It requires
exposing some more information to userspace, for a couple of reasons :
1) Cannonlake introduces asymetric slices (i.e. not the same number
of subslices for each slice)
2) Depending on the parts, the frequency of the command stream
might be different (this is something we rely on for queries in
GL & Vulkan, as well as for parsing OA reports), it used to be
fixed enough in previous generation, that we could just hardcode
it in the device infos.
There are also a few cleanups after going through the whitelisted
registers.
Cheers,
