Bug ID: 105601
Summary: drm_wait_vblank log spam with reverse PRIME
(intel+nouveau)
Product: Drivers
Version: 2.5
Kernel Version: 4.2.2
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: mschiffer+misc@universe-factory.net
Regression: No
Setup: I use reverse PRIME with a primary intel and a secondary nouveau card. I
have enabled one output on each of the cards. The reverse PRIME (nouveau)
output is set as primary output via xrandr.
Whenever there's a DRI user on the reverse PRIME screen, the following message
gets written to my kernel log once for each buffer swap:
[drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x7d, supported mask
0x7400003f
Both DRI2 and DRI3 cause this behaviour.
Depending on the exact setup (DRI2/DRI3, different DRI users), I also get
slightly different messages:
[drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x15d, supported
mask 0x7400003f
[drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x400015d, supported
mask 0x7400003f
Hardware:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [Quadro NVS 4200M]
(rev a1)

This is a (xf86-video-nouveau?) userspace bug, it's passing invalid arguments
to the DRM_IOCTL_WAIT_VBLANK ioctl.
