      drm/i915/gvt: Fix PTE write flush for taking runtime pm properly · 5ad59bf0
      Zhenyu Wang authored
      Make sure to take runtime pm when write PTE flush which ensure to
      write to hw properly. This fixes warning during mdev/vgpu creation
      which will do ggtt reset.

      drm/i915/gvt: remove some debug messages in scheduler timer handler · 954180aa
      Zhenyu Wang authored
      As those debug messages might appear in every timer call for scheduler,
      it's too noisy, eat too much log and aren't meaningful. So remove them.
