log from dmesg

I get these two non-fatal errors with gnome-shell:

[  164.903589] nouveau E[  PGRAPH][0000:01:00.0] DATA_ERROR INVALID_VALUE

Comment 1 Ilia Mirkin 2014-05-18 14:51:31 UTC 
Are there any rendering issues, or just these errors?

$ lookup -a 92 -d NV01_SUBCHAN -- -v obj-class NV84_3D e04 0xfebf0000
SCISSOR_HORIZ[0] => { MIN = 0 | MAX = 65215 }
$ lookup -a 92 -d NV01_SUBCHAN -- -v obj-class NV84_3D e08 0xfebf0000
SCISSOR_VERT[0] => { MIN = 0 | MAX = 65215 }

Those indeed appear to be invalid. I thought I had a thing clamping the value... What version of mesa are you using?

Hm, looks like the clamping is missing on the blit_3d path, but that'd only be an issue if someone had specified negative scissor bounds... hopefully the upper layers disallow that.

probably I have that issue/artifact: sometime, portion of a window isn't drawed but because simply gray 

mesa-10.1.3-1

I don't have "lookup" command and I don't find how to get it....teach it to me

Can you check if this still happens with mesa 10.2-rc3? This should have the clamping logic I mentioned above. (Except in the 3d blit path, but I'm hoping that's not the issue.)

lookup is from envytools. You shouldn't need to use it, unless you're interested in nouveau dev. That was just to decode the errors.

at the moment I can't try, but when I can I'll do it !
