drm: Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ to UAPI

2017-05-22T07:49:48+00:00

Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI as a convenience. Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up through the atomic API, but realizing that userspace is likely to take shortcuts and assume that the enum values are what is sent over the wire. As a result these defines are provided purely as a convenience to userspace applications. Changes since v3: - Switched away from past tense in comments - Add define name change to previously mis-spelled DRM_REFLECT_X comment - Improved the comment for the DRM_MODE_REFLECT_ comment Changes since v2: - Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_ - Fix compilation errors - Changed comment formatting - Deduplicated comment lines - Clarified DRM_MODE_PROP_REFLECT_ comment Changes since v1: - Moved defines from drm.h to drm_mode.h - Changed define prefix from DRM_ to DRM_MODE_PROP_ - Updated uses of the defines to the new prefix - Removed include from drm_rect.c - Stopped using the BIT() macro Signed-off-by: Robert Foss Reviewed-by: Emil Velikov Reviewed-by: Sinclair Yeh Acked-by: Liviu Dudau Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20170519205017.23307-2-robert.foss@collabora.com

drm/i915: Pass intel_plane and intel_crtc to plane hooks

drm/i915: Add plane update/disable tracepoints

2017-03-03T14:50:10+00:00

Add tracepoints for plane programming. The tracepoints will dump the frame and scanline counters, so this can be used to verify eg. that the plane gets reprogrammed at the right time with respect to watermark programming (if we have appropriate tracepoints for that as well). v2: Rebase due to legacy cursor changes Signed-off-by: Ville Syrjälä Reviewed-by: Maarten Lankhorst Link: http://patchwork.freedesktop.org/patch/msgid/20170302171508.1666-16-ville.syrjala@linux.intel.com

drm/i915: Track visible planes in a bitmask

2017-03-03T14:50:09+00:00

In a lot of place we wish to know which planes on the crtc are actually visible, or how many of them there are. Let's start tracking that in a bitmask in the crtc state. We already track enabled planes (ie. ones with an fb and crtc specified by the user) but that's not quite the same thing as enabled planes may still end up being invisible due to clipping and whatnot.

drm/i915: Track pinned vma in intel_plane_state

2017-01-19T10:14:09+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

drm/i915: Add a cursor hack to allow converting legacy page flip to atomic, v3.

2016-12-19T16:48:52+00:00

Do something similar to vc4, only allow updating the cursor state in-place through a fastpath when the watermarks are unaffected. This will allow cursor movement to be smooth, but changing cursor size or showing/hiding cursor will still fall back so watermarks can be updated. Only moving and changing fb is allowed. Changes since v1: - Set page flip to always_unused for trybot. - Copy fence correctly, ignore plane_state->state, should be NULL. - Check crtc_state for !active and modeset, go to slowpath if the case. Changes since v2: - Make error handling work correctly.
