[Nouveau] [Bug 16978] New: "tile offscreen pixmaps" causing graphics corruption on NV50?
http://bugs.freedesktop.org/show_bug.cgi?id=16978
Summary: "tile offscreen pixmaps" causing graphics
corruption on
NV50?
Product: xorg
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
AssignedTo: nouveau at lists.freedesktop.org
ReportedBy: chris at chris-lamb.co.uk
QAContact: xorg-team at lists.x.org

Hi,
(Shamelessly Cc'ing Ben Skeggs as he authored the offending commits)
Am seeing some graphics corruption on nouveau with my 8600 GT consisting of odd
black or white speckles on some widgets.
It's especially noticable on the folder list of the Claws Mail mail client,
but
also appears as white horizontal lines in a gnome-terminal window after some
time. Please ask if a photo would be useful.
I've bisected it as follows:
* Working version:
- drm
401f77a2ef1d55feaccc13cdae1e5379f4cfec7e
i915: official name for GM45 chipset
Zhenyu Wang <zhenyu.z.wang at intel.com>
- nouveau
5c1deac8384413dc483238f60c366e98253c11d6
exa: pass window coords to m2mf-based UTS/DFS
Ben Skeggs <skeggsb at gmail.com>
* Broken version:
- drm
c7ed2c67916ee8058301c53b9d4690d81728fb95
nouveau: interface changes for nv5x 3d

nv50: tile offscreen pixmaps
Ben Skeggs <skeggsb at gmail.com>
I don't know whether it is nouveau or drm commit that is causing the issue -
the "bad" nouveau commit requires a newer drm than its working
neighbour (bumps
NOUVEAU_DRM_HEADER_PATCHLEVEL). I would guess it was the "tile offscreen
pixmaps" commit though.
Am running Linux 2.6.25/2.6.26 on x86_64.
Regards,

Please ask if a photo would be useful.Yeah I'm very much aware of the issue, there's probably some gaps in our understanding of how the tiled surface stuff works on nv5x chips. However, the commit also allowed me to implement Xv and XRENDER acceleration (the 3D engine *must* use tiled surfaces, it'll refuse anything else), and the corruption is minor in most cases - so I decided people could live with it for now. I will note that I use the driver myself, on my main desktop machine - so I eat my own dog food :) We'll figure it out eventually, but as we have no nice docs like the radeon guys it could take time.

Should be OK now, marking as fixed. Please re-open if it's not :)

Alas, this doesn't seem fixed for me; I'm still consistently seeing
minor
speckles on some widgets.
Ben, was you recent change to nouveau_xv.c intended to close this? If so,
I'm
fairly sure this issue is different from any xv corruption.
Regards,

http://bugs.freedesktop.org/show_bug.cgi?id=16978 --- Comment #4 from Ben Skeggs <skeggsb at gmail.com> 2009-01-12 17:28:42 PST --- No, the Xv commit was unrelated. Did you, by any chance, see if you were still effected by this bug with the patches listed at http://nouveau.freedesktop.org/wiki/NV50Support? An alternative to trying those patches is to use the "ng" branches of drm git, and xf86-video-nouveau git and see if the corruption appears there also. However, this isn't an option you'll want to currently use on a day-to-day basis, it's very buggy still. With either option you shouldn't see any rendering issues (though fwiw, I don't see any without them), if you still do, there's something else going on with you card that we'll need to track down. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

However, sometime over the last few months it cleared itself up. You can probably go ahead and close this bug now.
