2020-09-16drm/i915: Initialise outparam for error return from wait_for_registerChris Wilson
Just in case the caller passes in 0 for both slow&fast timeouts, make sure we initialise the stack value returned. Add an assert so that we don't make the mistake of passing 0 timeouts for the wait. drivers/gpu/drm/i915/intel_uncore.c:2011 __intel_wait_for_register_fw() error: uninitialized symbol 'reg_value'.

2020-09-16drm/ast: Enable CRTC before planesThomas Zimmermann
An active cursor plane requires a valid display mode. Change the commit_tail callback, so that it sets up the CRTC's mode before updating planes.

2020-09-16drm/ast: Program display mode in CRTC's atomic_enable()Thomas Zimmermann
This change simplifies ast's modesetting code. The display mode is now programmed from within the CRTC's atomic_enable(), which only runs if we actually want to program the mode. Corresponding code in atomic_flush() is being removed. Also removed is atomic_begin(), which serves no purpose at all.

2020-09-16drm/ast: Disable planes while switching display modesThomas Zimmermann
The ast HW cursor requires the primary plane and CRTC to display at a valid mode and format. This is not the case while switching display modes, which can lead to the screen turing permanently dark. As a workaround, the ast driver now disables active planes while the mode or format switch takes place. It also synchronizes with the vertical refresh to give CRTC and planes some time to catch up on each other. The active planes planes (primary or cursor) will be re-enabled by each plane's atomic_update() function. v3: * move the logic into the CRTC's atomic_disable function v2: * move the logic into the commit-tail function Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20200914072236.19398-3-tzimmermann@suse.de

2020-09-16drm: mxsfb: check framebuffer pitchStefan Agner
The lcdif IP does not support a framebuffer pitch (stride) other than framebuffer width. Check for equality and reject the framebuffer otherwise. This prevents a distorted picture when using 640x800 and running the Mesa graphics stack. Mesa tries to use a cache aligned stride, which leads at that particular resolution to width != stride. Currently Mesa has no fallback behavior, but rejecting this configuration allows userspace to handle the issue correctly.

Don't check drm_crtc_state::active for this either, per its documentation in include/drm/drm_crtc.h: * Hence drivers must not consult @active in their various * &drm_mode_config_funcs.atomic_check callback to reject an atomic * commit. atomic_remove_fb disables the CRTC as needed for disabling the primary plane. This prevents at least the following problems if the primary plane gets disabled (e.g. due to destroying the FB assigned to the primary plane, as happens e.g. with mutter in Wayland mode): * The legacy cursor ioctl returned EINVAL for a non-0 cursor FB ID (which enables the cursor plane). * If the cursor plane was enabled, changing the legacy DPMS property value from off to on returned EINVAL. v2: * Minor changes to code comment and commit log, per review feedback.
