          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).

--- Comment #3 from Emil Velikov <emil.l.velikov@gmail.com> ---
The both issues should be resolved with
adbbdbac04f093c0abf946b1e93e4e5291808491 and
1d8eec8ba4a38fcee9d30e4fb5b3d67a9bff9db3 respectively. Landing with 3.14-rc8.

Give the stable 3.14 a try and feel free to reopen if it's still an issue.
