The return statement is redundant as there is a return statement immediately before it so we have dead code that can be removed. Also remove the unused declaration of ret.

This fixes a layout update race condition. We make sure the crtc mutex is locked before we dereference crtc->state. Otherwise the state might change under us. Since now we're already holding the crtc mutexes when reading the gui coordinates, protect them with the crtc mutexes rather than with the requested_layout mutex. Signed-off-by:

Make the connector is_implicit property immutable. As far as we know, no user-space application is writing to it. Also move the verification that all implicit display units scan out from the same framebuffer to atomic_check(). Signed-off-by:

Add an atomic helper to implement dirtyfb support. This is needed to support DSI command-mode panels with x11 userspace (ie. when we can't rely on pageflips to trigger a flush to the panel). v2: Modified the helper to use plane fb_damage_clips property and removed plane_state::dirty flag. v3: - Use uapi drm_mode_rect. - Support annotate flags. v4: Correct kernel doc.

FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions on the plane in framebuffer coordinates of the framebuffer attached to the plane. The layout of blob data is simply an array of "struct drm_mode_rect". Unlike plane src coordinates, damage clips are not in 16.16 fixed point. As plane src in framebuffer cannot be negative so are damage clips. In damage clip, x1/y1 are inclusive and x2/y2 are exclusive. This patch also exports the kernel internal drm_rect to userspace as drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient to represent damage for current plane size. Driver which are interested in enabling FB_DAMAGE_CLIPS property for a plane should enable this property using drm_plane_enable_damage_clips. v2: - Input validation on damage clips against framebuffer size. - Doc update, other minor changes.

drm/imx: update image-convert with fixes for multi-tiled scaling Update the ipu-v3 mem2mem image-convert code, with some fixes for race conditions, alignment issues, and visual artifacts due to tile alignment and scaling factor issues when scaling images larger than hardware limitations in multiple tiles. This will allow the V4L2 mem2mem scaler driver to write output images larger than 1024x1024 pixels. Also switch drm/imx source files to SPDX license identifiers, constify struct clk_ops in imx-tve, and add a timeout warning to the busy wait in ipu_plane_disable(). Signed-off-by:

This is the same as the default drm_gem_dumb_map_offset() implementation, except that this one missed the ban on userspace mapping an imported dmabuf (which seems like intended common behavior for drivers). Signed-off-by:

This change is an attempt to handle the alternate clock for the CEA mode. 60Hz vs. 59.94Hz, 30Hz vs 29.97Hz or 24Hz vs 23.97Hz on the Amlogic Meson SoC DRM Driver pixel clock generation. The actual clock generation will be moved to the Common Clock framework once all the video clock are handled by the Amlogic Meson SoC clock driver, then these alternate timings will be handled in the same time in a cleaner fashion.

Our hardware requires the pitch to be an even number when using YUV formats with the frontend. Implement a driver-specific callback for GEM dumb allocation that sets the pitch accordingly. Since only the bpp is passed (and not the format), we cannot really distinguish if this alignment is really required. Since it doesn't hurt to align the pitch anyway, always do it. Signed-off-by:

The frontend comes with two "channels", that can be configured independently. When used in YUV mode, the first channel (CH0) represents the luminance component while the second channel (CH1) represents the chrominance. In RGB mode, both have to be configured the same way. Use variables (with the YUV terminology) for each channel's dimensions, calculating the chroma dimensions from the luma dimensions and the sub-sampling factors from the format description. Since the configured size only has pixel precision, the fractional fixed-point part of the source size is dropped for both components to ensure that the scaling factors are accurate. Signed-off-by:
