Thomas Zimmermann 1fe1821549 drm/ast: Acquire I/O-register lock in atomic_commit_tail function ... Hold I/O-register lock in atomic_commit_tail to protect all pipeline updates at once. Protects modesetting against concurrent EDID reads. Complex modesetting operations involve mode changes and plane updates. These steps used to be protected individually against concurrent I/O. Make all this atomic wrt to reading display modes via EDID. The EDID code in the connector's get_modes helper already acquires the necessary lock. A similar issue was fixed in commit 2d70b9a148 ("drm/mgag200: Acquire I/O-register lock in atomic_commit_tail function") for mgag200. v2: * fix typo in commit message (Jocelyn) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Tested-by: Jocelyn Falempe <jfalempe@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221013112923.769-2-tzimmermann@suse.de		2022-10-16 11:15:31 +02:00
