[Intel-gfx] [PATCH v12 00/22] Enable OA unit for Gen 8 and 9 in i915 perf

[Lionel Landwerlin]

Hi all,

Here are the changes from the previous series :

 * Included patches 9, 10 & 11 from Chris to have sseu configuration
   stored per context (but not exposed to userspace)

 * In patches 12 & 13 querying the slice/subslice configuration now
   returns the configuration locked in by the OA unit or if the OA
   unit is not in use, the maximum capabilities of the system.

 * Patch 14 reworks how we query sets of registers to program for a
   given generation & metrics set. We weren't dealing with multiple
   slices turned on properly.

 * In patch 16, the update of context saved registers for programming
   the OA unit has been reworked to make sure we hand back to
   userspace a system where all the context have been properly
   udpated.
   We also take care to lock the sseu configuration using either the
   monitored context or the maximum of the system capabilities (if
   we're doing system wide monitoring).

 * Patches 20, 21 & 22 add support for Kabylake & Geminilake
   generations (still Gen9 based).

Cheers,
