kernel log with nouveau.reg_debug=0x600
When I try to run the mesa demos on the EGL/DRM backend I get a corrupted
screen.
You can find the demos here:
http://cgit.freedesktop.org/mesa/demos/tree/src/egl/opengl
The binaries for the EGL/DRM backend have a "_screen" suffix.
The demos are using eglut with the eglut_screen/drm backend.
The following kernel errors are printed:
[drm] nouveau 0000:01:00.0: EvoCh 0 Mthd 0x086c Data 0x00005564 (0x0084 0x04)
[drm] nouveau 0000:01:00.0: EvoCh 1 Mthd 0x080c Data 0x00005564 (0x0084 0x04)
You can find a screenshot and an kernel log with the "nouveau.reg_debug=0x600"
flag in the attachment.
Kernel 3.6.0 RC5 on NV50.
