2019-05-20drm: Remove users of drm_format_(horz|vert)_chroma_subsamplingMaxime Ripard
drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling are basically a lookup in the drm_format_info table plus an access to the hsub and vsub fields of the appropriate entry. Most drivers are using this function while having access to the entry already, which means that we will perform an unnecessary lookup. Removing the call to these functions is therefore more efficient. Some drivers will not have access to that entry in the function, but in this case the overhead is minimal (we just have to call drm_format_info() to perform the lookup) and we can even avoid multiple, inefficient lookups in some places that need multiple fields from the drm_format_info structure. This is amplified by the fact that most of the time the callers will have to retrieve both the vsub and hsub fields, meaning that they would perform twice the lookup.

2019-02-22drm/imx: ipuv3-plane: add zpos propertyPhilipp Zabel
Add a zpos property to planes. Call drm_atomic_helper_check() instead of calling drm_atomic_helper_check_modeset() and drm_atomic_check_planes() manually. This effectively adds a call to drm_atomic_normalize_zpos() before checking planes. Reorder atomic update to allow changing plane zpos without modeset. Note that the initial zpos is set in ipu_plane_state_reset(). The initial value set in ipu_plane_init() is just for show. The zpos parameter of drm_plane_create_zpos_property() is ignored because the newly created plane do not have state yet.

2017-07-17drm/imx: fix typo in ipu_plane_formats[]Laurentiu Palcu
The BGRA8888 appears twice in the ipu_plane_formats[] list. The duplicate should be BGRX8888. The original commit is: commit 59d6b7189a96 ("drm/imx: ipuv3-plane: enable support for RGBX8888 and RGBA8888 pixel formats") Signed-off-by: Laurentiu Palcu <laurentiu.palcu@nxp.com> Fixes: 59d6b7189a96 ("drm/imx: ipuv3-plane: enable support for RGBX8888 and RGBA8888 pixel") Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2017-07-17drm/imx: lock scanout transfers for consecutive burstsPhilipp Zabel
Because of its shallow queues and limited reordering ability, the i.MX6Q memory controller likes AXI bursts of consecutive addresses a lot. To optimize memory access performance, lock the IPU scanout channels for a number of burst accesses each, before switching to the next channel. The burst size and length of a locked burst chain are chosen not to overshoot the stride. Enabling the 8-burst channel lock on a single 1920x1080@60Hz RGBx scanout (474 MiB/s of 64-byte IPU memory read accesses) reduces the reported memory controller busy cycles from 46% to below 28% on an otherwise idle i.MX6Q.

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
2017-03-16drm/imx: use PRG/PRE when possibleLucas Stach
Allow the planes to use the PRG/PRE units as linear prefetchers when possible. This improves DRAM efficiency a bit and reduces the chance for display underflow when the memory subsystem is under load. This does not yet support scanning out tiled buffers directly, as this needs more work, but it already wires up the basic interaction between imx-drm, the IPUv3 driver and the PRG and PRE drivers.

2017-03-15drm/imx: ipuv3-plane: add support for separate alpha planesPhilipp Zabel
The IPUv3 can read 8-bit alpha values from a separate plane buffer using a companion IDMAC channel driven by the Alpha Transparency Controller (ATC) for the graphics channels. The conditional read mechanism allows to reduce memory bandwidth by skipping reads of color data for completely transparent bursts. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2017-03-15drm/imx: extend drm_plane_state_to_eba for separate channel supportPhilipp Zabel

2017-03-15drm/imx: add deferred plane disablingPhilipp Zabel
The DP (display processor) channel disable code tried to busy wait for the DP sync flow end interrupt status bit when disabling the partial plane without a full modeset. That never worked reliably, and it was disabled completely by the recent "gpu: ipu-v3: remove IRQ dance on DC channel disable" patch, causing ipu_wait_interrupt to always time out after 50 ms, which in turn would trigger a timeout in drm_atomic_helper_wait_for_vblanks. This patch changes ipu_plane_atomic_disable to only queue a DP channel register update at the next frame boundary and set a flag, which can be done without any waiting whatsoever. The imx_drm_atomic_commit_tail then calls a new ipu_plane_disable_deferred function that does the actual IDMAC teardown of the planes that are flagged for deferred disabling, after waiting for the vblank.

2017-03-15gpu: ipu-v3: add unsynchronised DP channel disablingPhilipp Zabel
When disabling the foreground DP channel during a modeset, the DC is already disabled without waiting for end of frame. There is no reason to wait for a frame boundary before updating the DP registers in that case. Add support to apply updates immediately. No functional changes, yet.

2016-12-15drm: Replace 'format->format' comparisons to just 'format' comparisonsVille Syrjälä
Rather than compare the format u32s of two format infos, we can direclty compare the format info pointers themselves. Noramlly all the ->format pointers all point to somwehere in the big array, so this is a valid way to test for equality. Also drivers may want to point ->format at a private format info struct instead (eg. for special compressed formats with extra planes), so just comparing the pixel format values wouldn't necessaritly even work.
