      drm/i915: Move vblank evasion to commit (v4) · c34c9ee4
      Matt Roper authored
      Move the vblank evasion up from the low-level, hw-specific
      update_plane() handlers to the general plane commit operation.
      Everything inside commit should now be non-sleeping, so this brings us
      closer to how vblank evasion will behave once we move over to atomic.
      
      v2:
       - Restore lost intel_crtc->active check on vblank evasion
      
      v3:
       - Replace assert_pipe_enabled() in intel_disable_primary_hw_plane()
         with an intel_crtc->active test; it turns out assert_pipe_enabled()
         grabs some mutexes and can sleep, which we can't do with interrupts
         disabled.
      
      v4:
       - Equivalent to v2; v3 change is now squashed into an earlier patch
         of the series.  (Ander).

      drm/i915: Refactor work that can sleep out of commit (v7) · 32b7eeec
      Matt Roper authored
      Once we integrate our work into the atomic pipeline, plane commit
      operations will need to happen with interrupts disabled, due to vblank
      evasion.  Our commit functions today include sleepable work, so those
      operations need to be split out and run either before or after the
      atomic register programming.
      
      The solution here calculates which of those operations will need to be
      performed during the 'check' phase and sets flags in an intel_crtc
      sub-struct.  New intel_begin_crtc_commit() and
      intel_finish_crtc_commit() functions are added before and after the
      actual register programming; these will eventually be called from the
      atomic plane helper's .atomic_begin() and .atomic_end() entrypoints.
      
      v2: Fix broken sprite code split
      
      v3: Make the pre/post commit work crtc-based to match how we eventually
          want this to be called from the atomic plane helpers.
      
      v4: Some platforms that haven't had their watermark code reworked were
          waiting for vblank, then calling update_sprite_watermarks in their
          platform-specific disable code.  These also need to be flagged out
          of the critical section.
      
      v5: Sprite plane test for primary show/hide should just set the flag to
          wait for pending flips, not actually perform the wait.  (Ander)
      
      v6:
       - Rebase onto latest di-nightly; picks up an important runtime PM fix.
       - Handle 'wait_for_flips' flag in intel_begin_crtc_commit(). (Ander)
       - Use wait_for_flips flag for primary plane update rather than
         performing the wait in the check routine.
       - Added kerneldoc to pre_disable/post_enable functions that are no
         longer static.  (Ander)
       - Replace assert_pipe_enabled() in intel_disable_primary_hw_plane()
         with an intel_crtc->active test; it turns out assert_pipe_enabled()
         grabs some mutexes and can sleep, which we can't do with interrupts
         disabled.
      
      v7:
       - Check for fb != NULL when deciding whether the sprite plane hides the
         primary plane during a sprite update.  (PRTS)

      drm/i915: fix build for CONFIG_BUG=n · 2f3408c7
      Jani Nikula authored
      If CONFIG_BUG=n __WARN_printf won't be defined leading to the below
      build failure. The double underscores should have told us to steer clear
      of it anyway.
      
      drivers/gpu/drm/i915/intel_display.c: In function ‘assert_pll’:
      drivers/gpu/drm/i915/intel_display.c:1027:2: error: implicit declaration
      of function ‘__WARN_printf’ [-Werror=implicit-function-declaration]
        I915_STATE_WARN(cur_state != state,
      
      Use WARN(1, ...) instead. It handles CONFIG_BUG=n gracefully and, with
      the constant condition, a sane compiler should reduce it to
      __WARN_printf.

      ALSA: hda: add component support · d7055bd6
      Imre Deak authored
      Register a component master to be used to interface with the i915
      driver. This is meant to replace the current interface which is based on
      module symbol lookups.
      
      Note that currently we keep the existing behavior and pin the i915
      module while the hda driver is loaded. Using the component interface
      allows us to remove this dependency once support for dynamically
      enabling / disabling the HDMI functionality is added to the driver.
      
      v2:
      - change roles between the hda and i915 components (Daniel)
      v3:
      - rename display_component to audio_component (Daniel)
      v4:
      - move removal of i915_powerwell.h from this patch to the next (Takashi)
      - request_module fails if module support isn't enabled, so ignore
        any error it returns and depend on the following NULL check of the
        component ops (Takashi)
      - change over to using dev_* instead of pr_* (Takashi)

      ALSA: hda: pass intel_hda to all i915 interface functions · 926981ae
      Imre Deak authored
      chip is already passed to most of the i915 interface functions. Unify
      the interface by passing intel_hda instead of chip and passing it to all
      functions. Passing intel_hda instead of chip makes more sense since this
      is an intel specific interface. Also in an upcoming patch we will use
      intel_hda in all of these functions so by passing intel_hda we can save
      on some pointer casts from chip to intel_hda.
      
      This will be needed by an upcoming patch adding component support.
      
      No functional change.

      Pull btrfs fixes from Chris Mason:
       "None of these are huge, but my commit does fix a regression from 3.18
        that could cause lost files during log replay.
      
        This also adds Dave Sterba to the list of Btrfs maintainers.  It
        doesn't mean we're doing things differently, but Dave has really been
        helping with the maintainer workload for years"
