drm/i915/fbdev: Stop repeating tile configuration on stagnation

2017-04-18T04:59:33+00:00

commit b717a0392530ae8da0da041abe5c3a6098b55660 upstream. If we cease making progress in finding matching outputs for a tiled configuration, stop looping over the remaining unconfigured outputs. v2: Use conn_seq (instead of pass) to only apply tile configuration on first pass.

drm/i915: Track pinned vma in intel_plane_state

2017-02-01T09:45:21+00:00

With atomic plane states we are able to track an allocation right from preparation, during use and through to the final free after being swapped out for a new plane. We can couple the VMA we pin for the framebuffer (and its rotation) to this lifetime and avoid all the clumsy lookups in between. v2: Remove residual vma on plane cleanup (Chris) v3: Add a description for the vma destruction in intel_plane_destroy_state (Maarten) References: https://bugs.freedesktop.org/show_bug.cgi?id=98829 Signed-off-by: Chris Wilson Signed-off-by: Maarten Lankhorst Link: http://patchwork.freedesktop.org/patch/msgid/20170116152131.18089-1-chris@chris-wilson.co.uk Acked-by: Joonas Lahtinen (cherry picked from commit be1e341513ca23b0668b7b0f26fa6e2ffc46ba20) Signed-off-by: Jani Nikula Link: http://patchwork.freedesktop.org/patch/msgid/1485854491-27389-3-git-send-email-maarten.lankhorst@linux.intel.com

drm: Nuke modifier[1-3]

2016-11-17T10:58:09+00:00

It has been suggested that having per-plane modifiers is making life more difficult for userspace, so let's just retire modifier[1-3] and use modifier[0] to apply to the entire framebuffer. Obviosuly this means that if individual planes need different tiling layouts and whatnot we will need a new modifier for each combination of planes with different tiling layouts. For a bit of extra backwards compatilbilty the kernel will allow non-zero modifier[1+] but it require that they will match modifier[0]. This in case there's existing userspace out there that sets modifier[1+] to something non-zero with planar formats. Mostly a cocci job, with a bit of manual stuff mixed in. @@ struct drm_framebuffer *fb; expression E; @@ - fb->modifier[E] + fb->modifier @@ struct drm_framebuffer fb; expression E; @@ - fb.modifier[E] + fb.modifier Cc: Kristian Høgsberg Cc: Ben Widawsky Cc: Rob Clark Cc: Daniel Vetter Cc: Tomeu Vizoso Cc: dczaplejewicz@collabora.co.uk Suggested-by: Kristian Høgsberg Acked-by: Ben Widawsky Acked-by: Daniel Stone Acked-by: Rob Clark Signed-off-by: Ville Syrjälä Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1479295996-26246-1-git-send-email-ville.syrjala@linux.intel.com

drm/i915: pdev cleanup

2016-08-22T11:19:52+00:00

In an effort to simplify things for a future push of dev_priv instead of dev wherever possible, always take pdev via dev_priv where feasible, eliminating the direct access from dev. Right now this only eliminates a few cases of dev, but it also obviates that we pass dev into a lot of functions where dev_priv would be the more obvious choice. v2: Fixed one more place missing in the previous patch set Signed-off-by: David Weinehall Link: http://patchwork.freedesktop.org/patch/msgid/20160822103245.24069-5-david.weinehall@linux.intel.com Reviewed-by: Chris Wilson Signed-off-by: Chris Wilson

drm/i915: Introduce i915_ggtt_offset()

2016-08-15T10:01:14+00:00

This little helper only exists to safely discard the upper unused 32bits of the general 64-bit VMA address - as we know that all Global GTT currently are less than 4GiB in size and so that the upper bits must be zero. In many places, we use a u32 for the global GTT offset and we want to document where we are discarding the full VMA offset.
