In the next patch, we will expose the ability to reconfigure the slices,
subslice and eu per context. To facilitate that, store the current
configuration on the context, which is initially set to the device
default upon creation.
There's another wrinkle in that we need to record this in intel_context
(i.e. per engine). Is OA limited to RCS?

It's really ad-hoc.
Reports produced by the OA unit contain 3 sets of counters :
- A counters are completely RCS related
- B & C counters can be anywhere in the GPU
And up to Gen10 the OA unit is part of RCS.
