Align pitch to multiples of 8 pixels for bpp values that do not map to RGB formats. The call to drm_driver_color_mode_format() fails with DRM_INVALID_FORMAT in these cases. Fall back to manually computing the pitch alignment from which drm_mode_size_dumb() can compute the correct pitch. Fixes userspace that allocates dumb buffers for YUV formats, where bpp equals 12.

2025-10-30drm/imx: parallel-display: convert to devm_drm_bridge_alloc() APILuca Ceresoli1-9/+7
This is the new API for allocating DRM bridges. This conversion was missed during the initial conversion of all bridges to the new API. Thus all kernels with commit 94d50c1a2ca3 ("drm/bridge: get/put the bridge reference in drm_bridge_attach/detach()") and using this driver now warn due to drm_bridge_attach() incrementing the refcount, which is not initialized without using devm_drm_bridge_alloc() for allocation. To make the conversion simple and straightforward without messing up with the drmm_simple_encoder_alloc(), move the struct drm_bridge from struct imx_parallel_display_encoder to struct imx_parallel_display. Also remove the 'struct imx_parallel_display *pd' from struct imx_parallel_display_encoder, not needed anymore.

The imx-ipuv3 atomic_check implementation uses the deprecated drm_atomic_get_existing_crtc_state() helper. This hook is called as part of the global atomic_check, thus before the states are swapped.

2025-09-29drm/gem-dma: Compute dumb-buffer sizes with drm_mode_size_dumb()Thomas Zimmermann1-1/+3
Call drm_mode_size_dumb() to compute dumb-buffer scanline pitch and buffer size. Align the pitch to a multiple of 8. Push the current calculation into the only direct caller imx. Imx's hardware requires the framebuffer width to be aligned to 8. The driver's current approach is actually incorrect, as it only guarantees this implicitly and requires bpp to be a multiple of 8 already. A later commit will fix this problem by aligning the scanline pitch such that an aligned width still fits into each scanline's memory. A number of other drivers are build on top of gem-dma helpers and implement their own dumb-buffer allocation. These drivers invoke drm_gem_dma_dumb_create_internal(), which is not affected by this commit. v5: - avoid reset of arguments (Tomi) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Link: https://lore.kernel.org/r/20250821081918.79786-4-tzimmermann@suse.de

2025-03-20drm/bridge: Add encoder parameter to drm_bridge_funcs.attachMaxime Ripard1-1/+2
The drm_bridge structure contains an encoder pointer that is widely used by bridge drivers. This pattern is largely documented as deprecated in other KMS entities for atomic drivers. However, one of the main use of that pointer is done in attach to just call drm_bridge_attach on the next bridge to add it to the bridge list. While this dereferences the bridge->encoder pointer, it's effectively the same encoder the bridge was being attached to. We can make it more explicit by adding the encoder the bridge is attached to to the list of attach parameters. This also removes the need to dereference bridge->encoder in most drivers.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds6-6/+6
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.
