drm/mediatek: Fix iommu fault by swapping FBs after updating plane state According to the comment in drm_atomic_helper_async_commit(), we should make sure FBs have been swapped, so that cleanups in the new_state performs a cleanup in the old FB. So we should move swapping FBs after calling mtk_plane_update_new_state(), to avoid using the old FB which could be freed.

drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting, but currently located next to framebuffer helpers. Move it to GEM atomic helpers, rename it slightly and adopt the drivers. Same for the rsp simple-pipe helper. Compile-tested with x86-64, aarch64 and arm. The patch is fairly large, but there are no functional changes. v3: * remove out-comented line in drm_gem_framebuffer_helper.h (Maxime) v2: * rename to drm_gem_plane_helper_prepare_fb() (Daniel) * add tutorial-style documentation Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maxime Ripard <mripard@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210222141756.7864-1-tzimmermann@suse.de

drm/mediatek: don't open-code drm_gem_fb_create Aside: There's a few other fb_create implementations which simply check for valid buffer format (or an approximation thereof), and then call drm_gem_fb_create. For atomic drivers at least we could walk all planes and make sure the format/modifier combo is valid, and remove even more code. For non-atomic drivers that's not possible, since the format list for the primary buffer might be garbage (and most likely it is). Also delete mtk_drm_fb.[hc] since it would now only contain one function.

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>

drm/mediatek: Use drm_plane_helper_check_state() Replace the use of drm_plane_helper_check_update() with drm_plane_helper_check_state() since we have a plane state. This also eliminates the double clipping the driver was doing in both check and commit phases). And it should fix src coordinate addr adjustement. Previously the driver was expecting negative dst coordinates after clipping, which is not going happen, so any clipping induced addr adjustment simply didn't happen. Neither did the driver respect any user configured src coordinates, so panning and such would have been totally broken. It should be all good now.
