There is little harm in ignoring fractional coordinates (they just get truncated). Without this: modetest -M vc4 -F tiles,gradient -s 32:1920x1080-60 -P89@74:1920x1080*.1.1@XR24 is rejected. We have the same issue in Kodi when trying to use zoom options on video. Note: even if all coordinates are fully integer. e.g. src:[0,0,1920,1080] dest:[-10,-10,1940,1100] it will still get rejected as drm_atomic_helper_check_plane_state uses drm_rect_clip_scaled which transforms this to fractional src coords Fixes: 21af94cf ("drm/vc4: Add support for scaling of display planes.")

The core clock computation takes into account both the load due to the input (ie, planes) and its output (ie, encoders). However, while the input load needs to consider all the planes, and thus sum all of their associated loads, the output happens mostly in parallel. Therefore, we need to consider only the maximum of all the output loads, and not the sum like we were doing. This resulted in a clock rate way too high which could be discarded for being too high by the clock framework. Since recent changes, the clock framework will even downright reject it, leading to a core clock being too low for its current needs. Fixes: 16e10105 ("drm/vc4: Increase the core clock based on HVS load") Signed-off-by:

We currently ignore the clk_set_min_rate return code assuming it would succeed. However, it can fail if we ask for a rate higher than the current maximum for example. Since we can't fail in atomic_commit, at least warn on failure. Signed-off-by:

vc4_drv isn't necessarily under the /soc node in DT as it is a virtual device, but it is the one that does the allocations. The DMA addresses are consumed by primarily the HVS or V3D, and those require VideoCore cache alias address mapping, and so will be under /soc. During probe find the a suitable device node for HVS or V3D, and adopt the DMA configuration of that node. Cc: <stable@vger.kernel.org> Signed-off-by:

Clip memory range to screen-buffer size to avoid out-of-bounds access in fbdev deferred I/O's damage handling. Fbdev's deferred I/O can only track pages. From the range of pages, the damage handler computes the clipping rectangle for the display update. If the fbdev screen buffer ends near the beginning of a page, that page could contain more scanlines. The damage handler would then track these non-existing scanlines as dirty and provoke an out-of-bounds access during the screen update. Hence, clip the maximum memory range to the size of the screen buffer. While at it, rename the variables min/max to min_off/max_off in drm_fb_helper_deferred_io(). This avoids confusion with the macros of the same name. Reported-by:

Implement DRM's aperture helpers under video/ for sharing with other sub-systems. Remove DRM-isms from the interface. The helpers track the ownership of framebuffer apertures and provide hand-over from firmware, such as EFI and VESA, to native graphics drivers. Other subsystems, such as fbdev and vfio, also have to maintain ownership of framebuffer apertures. Moving DRM's aperture helpers to a more public location allows all subsystems to interact with each other and share a common implementation. The aperture helpers are selected by the various firmware drivers within DRM and fbdev, and the VGA text-console driver. The original DRM interface is kept in place for use by DRM drivers. v3: * prefix all interfaces with aperture_ (Javier) * rework and simplify documentation (Javier) * rename struct dev_aperture to struct aperture_range * rebase onto latest DRM * update MAINTAINERS entry Signed-off-by:

backlight_properties.fb_blank is deprecated. The states it represents are handled by other properties; but instead of accessing those properties directly, drivers should use the helpers provided by backlight.h. Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.
