[Nouveau] [Bug 101191] New: [NVC3] Vsync stops working after mode changes in nouveau DDX
https://bugs.freedesktop.org/show_bug.cgi?id=101191 Bug ID: 101191 Summary: [NVC3] Vsync stops working after mode changes in nouveau DDX Product: xorg Version: 7.7 (2012.06) Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/nouveau Assignee: nouveau at lists.freedesktop.org Reporter: z411 at omaera.org QA Contact: xorg-team at lists.x.org Hello, I've encountered this weird issue where Vsync suddenly stops working after I manipulate modes on the fly in some situations. I could reproduce it in 4 different situations, and I've attached logs respectively: (1) Only 1 monitor connected to DVI. Any mode change (resolution or refresh rate) will trigger the issue. (term_1.txt / xorg_1.txt) (2) 2 monitors connected (DVI+HDMI TV). Turning off the DVI monitor will immediately trigger the issue. (term_2.txt / xorg_2.txt) (3) 2 monitors connected (DVI+HDMI TV). Mode changes in DVI monitor won't trigger the issue anymore. But after turning off the HDMI monitor, mode changes in the DVI one will start triggering the issue again. (term_3.txt / xorg_3.txt) (4) 2 monitors connected (DVI+HDMI TV). Mode changes in HDMI monitor immediately trigger the issue. Note how Vsync is still working in the DVI one, though. (term_4.txt / xorg_4.txt) Needless to say, this will cause issues (for example) in mpv video player, where it'll suffer tearing and complain about inconsistent timing, both in opengl and vdpau modes. Distribution Debian Sid Linux 4.9.25 xorg 7.7 (server 1.19.3) xf86-video-nouveau 1.0.15 libdrm 2.4.74 This only happens with the nouveau DDX driver, as this issue doesn't occur with the modesetting one, therefore I assume it's a nouveau DDX bug (rather than mesa). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
