[Intel-gfx] [PATCH v14 00/14] Enable OA unit for Gen 8 and 9 in i915 perf

[Lionel Landwerlin]

Hi,

Here are the changes from v13 :

     * there is no more locking mechanism of the SSEU configuration on
       the whole system, instead we now make the i915 driver monitors
       the changes on submissions when OA is enabled and events are
       inserted in the perf stream to enable userspace to parse
       reports appropriately (this is reflected by changes in patch 6
       and patch 14).

     * now that we let SSEU configuration be configurable per context
       & engine, we need to reprogram the NOA muxes in between batches
       when OA is enabled (patch 13).

With exception of patch 6, I think patches 1 to 12 don't need much
looking at. In patch 6 the only bit that actually changed is the
gen8_configure_all_contexts() function.

The IGT tests for this are available here :
