Subject: [Bug 28411] New: Output polling causes latency every 10 seconds
Date: Sun, 6 Jun 2010 10:49:49 -0700 (PDT) [thread overview]
Message-ID: <bug-28411-502@http.bugs.freedesktop.org/> (raw)
https://bugs.freedesktop.org/show_bug.cgi?id=28411
Summary: Output polling causes latency every 10 seconds
Product: DRI
Version: DRI CVS
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: General
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: marius.groeger@web.de
The output polling in drm_crtc_helper.c added in this commit:
commit eb1f8e4f3be898df808e2dfc131099f5831d491d
Author: Dave Airlie <airlied@redhat.com>
Date: Fri May 7 06:42:51 2010 +0000
causes drm latencies every 10 seconds. I observed them in mythtv.
Apparently the dev->mode_config.mutex is held for too long; if I remove the
mutex_lock/unlock for testing purposes the latencies are gone.
