[PATCH xf86-video-ati] Pass fb_id into drmmode_page_flip_target_absolute/relative

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Michel Dänzer <michel.daenzer@xxxxxxx>

drmmode->fb_id isn't what we need in the TearFree case. Fixes TearFree
freezing with

(WW) RADEON(0): flip queue failed in radeon_scanout_flip: No such file or directory

in the log file.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98834
Fixes: 1106b2f773ad ("Use DRM_MODE_PAGE_FLIP_TARGET_ABSOLUTE/RELATIVE flags when available")
Signed-off-by: Michel Dänzer <michel.daenzer at amd.com>
