2017-12-08drm/armada: fix UV swap codeRussell King
The UV swap code was not always programming things correctly when the source origin box has been offset. Fix this. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-10-16drm/armada: Replace drm_framebuffer_reference/unreference() with _get/put()Haneen Mohammed
This patch replace instances of drm_framebuffer_reference/unreference with *_get/put() suffixes, because get/put is shorter and consistent with the kernel use of *_get/put suffixes. This was done with the following Coccinelle script: @r1@ expression e; @@ ( -drm_framebuffer_reference(e); +drm_framebuffer_get(e); | -drm_framebuffer_unreference(e); +drm_framebuffer_put(e); ) Signed-off-by: Haneen Mohammed <hamohammed.sa@gmail.com> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/e1df1b3375faa819029559b11c32e10501c5c5d6.1505932812.git.hamohammed.sa@gmail.com
2017-08-01drm: Plumb modifiers through plane initBen Widawsky
This is the plumbing for supporting fb modifiers on planes. Modifiers have already been introduced to some extent, but this series will extend this to allow querying modifiers per plane. Based on this, the client to enable optimal modifications for framebuffers. This patch simply allows the DRM drivers to initialize their list of supported modifiers upon initializing the plane. v2: A minor addition from Daniel v3: * Updated commit message * s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu) * Remove some excess newlines (Liviu) * Update comment for > 64 modifiers (Liviu) v4: Minor comment adjustments (Liviu) v5: Some new platforms added due to rebase v6: Add some missed plane inits (or maybe they're new - who knows at this point) (Daniel) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Daniel Stone <daniels@collabora.com> (v2) Reviewed-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Daniel Stone <daniels@collabora.com>

2017-05-22drm: Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ to UAPIRobert Foss
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_<axis> 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 <robert.foss@collabora.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com> Acked-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20170519205017.23307-2-robert.foss@collabora.com

Also it thinks '...' is part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder in its place and got rid of it with sed afterwards.

2015-07-15drm/armada: fix overlay when partially off-screenRussell King
Fix the start address calculation when overlay is partially off screen. fb->bits_per_pixel is not set for YUV formats, and is always zero, which led to the first component always starting at zero. Use drm_format_plane_cpp() instead. This also revealed a problem in that YUYV formats toggle the U/V data for odd pixel start address offsets. We try to rectify that by toggling the U/V swap, which for the most part works, but seemingly introduces a flicker for one scan frame of swapped U/V. However, these changes result in an overall improvement. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2015-07-15drm/armada: convert overlay to use drm_plane_helper_check_update()Russell King

2015-07-15drm/armada: fix missing overlay wake-upRussell King
Nothing was waking up the overlay plane wait queue, so we were fully reliant on the HZ/25 wait timing out to make progress. Fix the lack of wake-up. We were also mis-handling the wait_event_timeout() return value - this returns an unsigned integer of the remaining time, or zero on timeout and the condition evaluated false. Checking this for less than zero is not sane. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2013-10-12DRM: Armada: Add Armada DRM driverRussell King
This patch adds support for the pair of LCD controllers on the Marvell Armada 510 SoCs. This driver supports: - multiple contiguous scanout buffers for video and graphics - shm backed cacheable buffer objects for X pixmaps for Vivante GPU acceleration - dual lcd0 and lcd1 crt operation - video overlay on each LCD crt via DRM planes - page flipping of the main scanout buffers - DRM prime for buffer export/import This driver is trivial to extend to other Armada SoCs. Included in this commit is the core driver with no output support; output support is platform and encoder driver dependent.
