      drm/i915/skl+: Use scaling amount for plane data rate calculation (v4) · 8d19d7d9
      Kumar, Mahesh authored
      if downscaling is enabled plane data rate increases according to scaling
      amount. take scaling amount under consideration while calculating plane
      data rate
      
      v2: Address Matt's comments, where data rate was overridden because of
      missing else.
      
      v3 (by Matt):
       - Add braces to 'else' branch to match kernel coding style
       - Adjust final calculation now that skl_plane_downscale_amount()
         returns 16.16 fixed point value instead of a decimal fixed point
      
      v4 (by Matt):
       - Avoid integer overflow by making sure final multiplication is
         treated as 64-bit.

      drm/i915/skl+: calculate plane pixel rate (v4) · 9c2f7a9d
      Kumar, Mahesh authored
      Don't use pipe pixel rate for plane pixel rate. Calculate plane pixel according
      to formula
      
      adjusted plane_pixel_rate = adjusted pipe_pixel_rate * downscale ammount
      
      downscale amount = max[1, src_h/dst_h] * max[1, src_w/dst_w]
      if 90/270 rotation use rotated width & height
      
      v2: use intel_plane_state->visible instead of (fb == NULL) as per Matt's
          comment.
      
      v3 (by Matt):
       - Keep downscale amount in 16.16 fixed point rather than converting to
         decimal fixed point.
       - Store adjusted plane pixel rate in plane state instead of the plane
         parameters structure that we no longer use.
      
      v4 (by Matt):
       - Significant rebasing onto latest atomic watermark work
       - Don't bother storing plane pixel rate in state; just calculate it
         right before the calls that make use of it.
       - Fix downscale calculations to actually use width values when
         computing downscale_w rather than copy/pasted height values.

      drm/i915/skl+: calculate ddb minimum allocation (v6) · cbcfd14b
      Kumar, Mahesh authored
      don't always use 8 ddb as minimum, instead calculate using proper
      algorithm.
      
      v2: optimizations as per Matt's comments.
      
      v3 (by Matt):
       - Fix boolean logic for !fb test in skl_ddb_min_alloc()
       - Adjust negative tiling format comparisons in skl_ddb_min_alloc() to
         improve readability.
      
      v4 (by Matt):
       - Rebase onto recent atomic watermark changes
       - Slight tweaks to code flow to make the logic more closely match the
         description in the bspec.
      
      v5 (by Matt):
       - Handle minimum scanline calculation properly for 4 & 8 bpp formats.
         8bpp isn't actually possible right now, but it's listed in the bspec
         so I've included it here for forward compatibility (similar to how
         we have logic for NV12).
      
      v6 (by Matt):
       - Calculate plane_bpp correctly for non-NV12 formats. (Mahesh)

      drm/i915: Don't try to calculate relative data rates during hw readout · edd4156f
      Matt Roper authored
      We don't actually read out full plane state during driver startup (only
      whether the primary plane is enabled/disabled), so all of the src/dest
      rectangles are invalid at this point.  However this calculation was
      needless anyway since we re-calculate them from scratch on the very
      first atomic transaction after boot anyway.

      drm/i915: Only ignore eDP ports that are connected · 457c52d8
      Chris Wilson authored
      If the VBT says that a certain port should be eDP (and hence fused off
      from HDMI), but in reality it isn't, we need to try and acquire the HDMI
      connection instead. So only trust the VBT edp setting if we can connect
      to an eDP device on that port.
      
      Fixes: d2182a66 (drm/i915: Don't register HDMI connectors for eDP ports on VLV/CHV)

      afee4d87 Revert "drm/i915: Avoid stalling on pending flips for legacy cursor updates"
      
      "drm/i915: Allow nonblocking update of pageflips" should have been
      split up, misses a proper commit message and seems to cause issues in
      the legacy page_flip path as demonstrated by kms_flip.
      
      "drm/i915: Make unpin async" doesn't handle the unthrottled cursor
      updates correctly, leading to an apparent pin count leak. This is
      caught by the WARN_ON in i915_gem_object_do_pin which screams if we
      have more than DRM_I915_GEM_OBJECT_MAX_PIN_COUNT pins.
      
      Unfortuantely we can't just revert these two because this patch series
      came with a built-in bisect breakage in the form of temporarily
      removing the unthrottled cursor update hack for legacy cursor ioctl.
      Therefore there's no other option than to revert the entire pile :(
      
      There's one tiny conflict in intel_drv.h due to other patches, nothing
      serious.
      
      Normally I'd wait a bit longer with doing a maintainer revert, but
      since the minimal set of patches we need to revert (due to the bisect
      breakage) is so big, time is running out fast. And very soon
      (especially after a few attempts at fixing issues) it'll be really
      hard to revert things cleanly.
      
      Lessons learned:
      - Not a good idea to rush the review (done by someone fairly new to
        the area) and not make sure domain experts had a chance to read it.
      
      - Patches should be properly split up. I only looked at the two
        patches that should be reverted in detail, but both look like the
        mix up different things in one patch.
      
      - Patches really should have proper commit messages. Especially when
        doing more than one thing, and especially when touching critical and
        tricky core code.
      
      - Building a patch series and r-b stamping it when it has a built-in
        bisect breakage is not a good idea.
      
      - I also think we need to stop building up technical debt by
        postponing atomic igt testcases even longer. I think it's clear that
        there's enough corner cases in this beast that we really need to
        have the testcases _before_ the next step lands.
