Subject: [Bug 76531] New: linux-3.14-rc7 radeon/nouveau runtime-suspend never coming back
Date: Sun, 23 Mar 2014 23:03:29 +0000 [thread overview]
Message-ID: <bug-76531-502@http.bugs.freedesktop.org/> (raw)

https://bugs.freedesktop.org/show_bug.cgi?id=76531
Priority: medium
Bug ID: 76531
Assignee: dri-devel@lists.freedesktop.org
Summary: linux-3.14-rc7 radeon/nouveau runtime-suspend never
coming back
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: bonbons67@internet.lu
Hardware: Other
Status: NEW
Version: XOrg CVS
Component: DRM/other
Product: DRI
Most recent testing: 3.14-rc7 mainline.
As suggested on IRC by imirkin, returning -EBUSY instead of -EINVAL from
nouveau_pmops_runtime_suspend() avoids driver to fall too far to the ground.
When returning -EINVAL connectors get being seen as "disconnected" and there is
no way to get them connected anymore.
When returning -EBUSY the connectors stay functional but DE (enlightenment)
complains about missing crtc and all that is visible is black background and a
cursor that response to mouse/trackpad.
Way to reproduce:
Have xorg running, then for each avtive output call:
xrandr --output $OUTPUT --off
When last output got marked off runtime-suspend kicks in.
Same/similar behavior has been observed on radeon (I don't remember the exact
kernel releases, but older ones got console to display when switching VTs while
newer failed to do so).
