[Intel-gfx] [PATCH] drm/i915: always pin hw_id for GVT context

[Zhenyu Wang]

Initially found issue with closed context debug check when pin
hw_id for GVT context, looks we should always pin hw_id for that
as GVT context is fixed for each vGPU life cycle, and we'd also
like to get pinned hw_id e.g for perf reason, etc.
