      DRM/i915: Get rid if the 'hotplug_supported_mask' in struct drm_i915_private. · 4f770a5b
      Egbert Eich authored
      Now since we have replaced the bits to show interest in hotplug IRQs
      we can go and nuke the 'hotplug_supported_mask'.

      DRM/i915: Remove i965_hpd_irq_setup. · bac56d5b
      Egbert Eich authored
      After
      "Convert HPD interrupts to make use of HPD pin assignment in encoders."
      This function is now basically the same as i915_hpd_irq_setup().
      
      Consolidating both functions in one requires one more check for
      I915_HAS_HOTPLUG(dev) in the i965 code path and one more check for
      IS_G4X(dev) in the i915 code path. These are considered harmless.

          drm/i915: Fixup hpd irq register setup ordering
      
      Egbert Eich's hpd rework blows up on pch-split platforms - it walks
      the encoder list before that has been set up completely. The new init
      sequence is:
      
      1. irq enabling
      2. modeset init
      3. hpd setup
      
      We need to move around the ibx setup a bit to fix this.
      
      Ville Syrjälä pointed out in his review that we can't touch SDEIER
      after the interrupt handler is set up, since that'll race with Paulo
      Zanoni's PCH interrupt race fix:

          drm/i915: also disable south interrupts when handling them
      
      We fix that by unconditionally enabling all interrupts in SDEIER, but
      masking them as-needed in SDEIMR. Since only the single-threaded
      setup/teardown (or suspend/resume) code touches that, no further
      locking is required.
      
      While at it also simplify the mask handling - we start out with all
      interrupts cleared in the postinstall hook, and never enable a hpd
      interrupt before hpd_irq_setup is called.
      
      And finally, for consistency rename the ibx hpd setup function to
      ibx_hpd_irq_setup.
      
      v2: Fix race around SDEIER writes (Ville).
      
      v3: Remove the superflous posting read for SDEIER, spotted by Ville.
      
      Ville also wondered whether we shouldn't clear SDEIIR, since now
      SDE interrupts are enabled before we have an irq handler installed.
      But the master interrupt control bit in DEIER is still cleared, so we
      should be fine.
