      drm/i915/icl: Ringbuffer interrupt handling · d4ccceb0
      Tvrtko Ursulin authored
      On Gen11 interrupt masks need to be clear to allow C6 entry.
      We keep them all enabled knowing that we generate extra
      interrupts.
      
      v2: Rebase.
      v3: Remove gen 11 extra check in logical_render_ring_init.
      v4: Rebase fixes.
      v5: Rebase/refactor.
      v6: Rebase.
      v7: Rebase.
      v8: Update comment and commit message (Daniele)

      drm/i915: Unwind vma pinning for intel_pin_and_fence_fb_obj error path · 7509702b
      Chris Wilson authored
      If we fail to acquire a fence when we must, we must unwind before
      reporting the error. Otherwise, we lose tracking of the vma pinning and
      eventually hit a bug like

      drm/i915/icl: remove port A/E lane sharing limitation. · 3d2011cf
      Mahesh Kumar authored
      Platforms before Gen11 were sharing lanes between port-A & port-E.
      This limitation is no more there.
      
      Changes since V1:
       - optimize the code (Shashank/Jani)
       - create helper function to get max lanes (ville)
      Changes since V2:
       - Include BIOS fail fix-up in same helper function (ville)
      Changes since V3:
       - remove confusing if/else (jani)
       - group intel_encoder initialization

      drm/i915/dp: move link rate arrays where they're used · 229675d5
      Jani Nikula authored
      Localize link rate arrays by moving them to the functions where they're
      used. Further clarify the distinction between source and sink
      capabilities. Split pre and post Haswell arrays, and get rid of the
      array size arithmetics. Use a direct rate value in the paranoia case of
      no common rates find.

      drm/i915: Consult aux_ch instead of port in ->get_aux_clock_divider() · 449059a9
      Ville Syrjälä authored
      While it seems totally unlikely that any system would mix a cpu/north
      aux channel with a pch/south port (or vice versa) we should still
      consult intel_dp->aux_ch rather than encoder->port when figuring out
      which clock is actually used by the aux ch.

      drm/i915: Don't deref request->ctx inside unlocked print_request() · 367a35a6
      Chris Wilson authored
      Although we protect the request itself, we don't lock inside
      intel_engine_dump() and so the request maybe retired as we peek into it.
      One consequence is that the request->ctx may be freed before we
      dereference it, leading to a use-after-free. Replace the hw_id we are
      peeking from inside request->ctx with the request->fence.context, with
      which we can still track from which context the request originated
      (although to tie to HW reports requires a little more legwork, but is
      good enough to follow the GEM traces).
