      drm/i915: add register macro definition style guide · 1aa920ea
      Jani Nikula authored
      This is not to try to force a new style; this is my interpretation of
      what the most common existing style is.
      
      With hopes I don't need to answer so many questions about style going
      forward.
      
      Start a new style section in the i915 document to bolt the register
      style guide into.

      drm/i915: Add format modifiers for Intel · 714244e2
      Ben Widawsky authored
      This was based on a patch originally by Kristian. It has been modified
      pretty heavily to use the new callbacks from the previous patch.
      
      v2:
        - Add LINEAR and Yf modifiers to list (Ville)
        - Combine i8xx and i965 into one list of formats (Ville)
        - Allow 1010102 formats for Y/Yf tiled (Ville)
      
      v3:
        - Handle cursor formats (Ville)
        - Put handling for LINEAR in the mod_support functions (Ville)
      
      v4:
        - List each modifier explicitly in supported modifiers (Ville)
        - Handle the CURSOR plane (Ville)
      
      v5:
        - Split out cursor and sprite handling (Ville)
      
      v6:
        - Actually use the sprite funcs (Emil)
        - Use unreachable (Emil)
      
      v7:
        - Only allow Intel modifiers and LINEAR (Ben)
      
      v8
        - Fix spite assert introduced in v6 (Daniel)
      
      v9
        - Change vendor check logic to avoid magic 56 (Emil)
        - Reorder skl_mod_support (Ville)
        - make intel_plane_funcs static, could be done as of v5 (Ville)
        - rename local variable intel_format_modifiers to modifiers (Ville)
          - actually use sprite modifiers
        - split out modifier/formats by platform (Ville)
      
      v10:
        - Undo vendor check from v9
      
      v11:
        - Squash CCS advertisement into this patch (daniels)
        - Don't advertise CCS on higher sprite planes (daniels)
      
      v12:
        - Don't advertise Y-tiled or CCS on any sprite planes, since we don't
          allocate enough DDB space for it to work. (daniels)

      drm/i915: Add render decompression support · 2e2adb05
      Ville Syrjälä authored
      SKL+ display engine can scan out certain kinds of compressed surfaces
      produced by the render engine. This involved telling the display engine
      the location of the color control surfae (CCS) which describes
      which parts of the main surface are compressed and which are not. The
      location of CCS is provided by userspace as just another plane with its
      own offset.
      
      Add the required stuff to validate the user provided AUX plane metadata
      and convert the user provided linear offset into something the hardware
      can consume.
      
      Due to hardware limitations we require that the main surface and
      the AUX surface (CCS) be part of the same bo. The hardware also
      makes life hard by not allowing you to provide separate x/y offsets
      for the main and AUX surfaces (excpet with NV12), so finding suitable
      offsets for both requires a bit of work. Assuming we still want keep
      playing tricks with the offsets. I've just gone with a dumb "search
      backward for suitable offsets" approach, which is far from optimal,
      but it works.
      
      Also not all planes will be capable of scanning out compressed surfaces,
      and eg. 90/270 degree rotation is not supported in combination with
      decompression either.
      
      This patch may contain work from at least the following people:

      * Daniel Vetter <daniel@ffwll.ch>
      * Ben Widawsky <ben@bwidawsk.net>
      
      v2: Deal with display workarounds 0390, 0531, 1125 (Paulo)
      v3: Pretend CCS tiles are regular 128 byte wide Y tiles (Jason)
          Put the AUX register defines to the correct place
          Fix up the slightly bogus rotation check
      v4: Use I915_WRITE_FW() due to plane update locking changes
          s/return -EINVAL/goto err/ in intel_framebuffer_init()
          Eliminate a bunch hardcoded numbers in CCS code

      drm/i915: Implement .get_format_info() hook for CCS · bbfb6ce8
      Ville Syrjälä authored
      SKL+ display engine can scan out certain kinds of compressed surfaces
      produced by the render engine. This involved telling the display engine
      the location of the color control surfae (CCS) which describes which
      parts of the main surface are compressed and which are not. The location
      of CCS is provided by userspace as just another plane with its own offset.
      
      By providing our own format information for the CCS formats, we should
      be able to make framebuffer_check() do the right thing for the CCS
      surface as well.
      
      Note that we'll return the same format info for both Y and Yf tiled
      format as that's what happens with the non-CCS Y vs. Yf as well. If
      desired, we could potentially return a unique pointer for each
      pixel_format+tiling+ccs combination, in which case we immediately be
      able to tell if any of that stuff changed by just comparing the
      pointers. But that does sound a bit wasteful space wise.
      
      v2: Drop the 'dev' argument from the hook
      v3: Include the description of the CCS surface layout
      v4: Pretend CCS tiles are regular 128 byte wide Y tiles (Jason)
      v5: Re-drop 'dev', fix commit message, add missing drm_fourcc.h
          description of CCS layout. (daniels)

      drm/i915: Supply the engine-id for our mock_engine() · 3ec0af7f
      Chris Wilson authored
      In the original selftest, we didn't care what the engine->id was, just
      that it could uniquely identify it. Later though, we started tracking
      the mock engines in the fixed size arrays around the drm_i915_private and
      so we now require their indices to be correct. This becomes an issue when
      using the standalone harness which runs all available tests at module load,
      and so we quickly assign an out-of-bounds index to an engine as we
      reallocate the mock GEM device between tests. It doesn't show up in
      igt/drv_selftest as that runs each subtest individually.
