[Nouveau] [Bug 64858] New: Nouveau sees invalid EDID for eDP-1 whenever that display is turned off
https://bugs.freedesktop.org/show_bug.cgi?id=64858
Priority: medium
Bug ID: 64858
Assignee: nouveau at lists.freedesktop.org
Summary: Nouveau sees invalid EDID for eDP-1 whenever that
display is turned off
QA Contact: xorg-team at lists.x.org
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: gspreemann at gmail.com
Hardware: x86-64 (AMD64)
Status: NEW
Version: unspecified
Component: Driver/nouveau
Product: xorg
With kernel 3.8.8 and 3.9.0, nouveau sees an EDID with incorrect checksum for
the display on eDP-1 as soon as that connector is turned off. Repeatedly
re-fetching that EDID causes so much stuttering that the system becomes
unusuable. A kworker thread rises to near 100% CPU usage, so I suspect the EDID
is being re-fetched repeatedly. Turning the connector back on restores normal
behavior (the correct EDID, with correct checksum, is obtained, and there is no
stuttering). Kernel 3.5.7.9 did not behave like this.
Extracting the correct EDID when the display is on and supplying it as a custom
EDID does not seem to prevent re-fetching of the invalid one. Passing
drm_kms_helper.poll=0 does not seem to prevent the re-fetching either.
I apologize in advance if it turns out that it is in fact my hardware that
simply supplies the wrong EDID when the display is turned off. In that case,
maybe one could add an option to stop re-fetching after N failed checksums? (I
guess that's not in the domain of nouveau, though...)

(The tx req timeout message is not always present. The EDID checksum failure is
repeated for as long as eDP-1 is disabled. As soon as eDP-1 is turned on, the
messages stop appearing and the stuttering described above stops.)

drm: run the hpd irq event code directly
All drivers already have a work item to run the hpd code, so we don't
need to launch a new one in the helper code. Dave Airlie mentioned
that the cancel+re-queue might paper over DP related hpd ping-pongs,
hence why this is split out.

Quick question: For older, working kernels do you also need to set the poll=0
option to get a useable system or does it work without any kernel option?

It does not need poll=0 in order to be symptom-free. More interestingly though, I accidentally booted into my current kernel (3.8.x with the patch from comment 5) without poll=0, and it also works fine. I am sorry if I overlooked this earlier. It could also be that my distribution has patched the kernel since May. I can look through the changelogs and/or try an upstream kernel when I have some free time (maybe this weekend). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

[Nouveau] [Bug 64858] [BISECTED] Nouveau sees invalid EDID for eDP-1 whenever that display is turned off
https://bugs.freedesktop.org/show_bug.cgi?id=64858 --- Comment #8 from Ilia Mirkin <imirkin at alum.mit.edu> --- Testing with an upstream kernel would be preferable, either nouveau/git or 3.11-rc7 (or 3.11 if it's out by then). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=64858 --- Comment #10 from gspr <gspreemann at gmail.com> --- With 3.11-rc7, I no longer see the same stuttering described in the initial bug report. There is, however, still a 100% load kworker thread, lots and lots of EDID checksum failed messages, and long periods of unresponsiveness when changing resolution. Adding drm_kms_helper.poll=N removes the repeated EDID checksum messages, but the system still becomes unresponsive for large stretches of time after changing resolution, and there's still a kworker thread at 100%. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=64858 --- Comment #11 from gspr <gspreemann at gmail.com> --- Disregard my comment 7 about not needing poll=0 for older, working kernels. I just realized that I had it set as a modprobe option, so it was still in effect when I tested without it as a boot option. I've checked again, and in reference to Vetter's comment 6: I *do* need poll=0 also for older kernels that did not need the patch. I'm very sorry for the misinformation. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
