Hi,
With the latest tilt-3.4 branch, I see these messages in the kernel while booting up:
[ 3.176330] twl_rtc twl_rtc: setting system clock to 2000-01-01 00:00:00 UTC (946684800) [ 3.185882] omap_vout omap_vout: 'hdmi' Display already enabled [ 3.192138] omap_vout omap_vout: 'hdmi' Display already enabled [ 3.198425] omap_vout omap_vout: Buffer Size = 3686400 [ 3.204925] omapdss OVERLAY error: check_overlay: paddr cannot be 0 [ 3.211578] omap_vout omap_vout: setup_overlay failed [ 3.216949] omap_vout omap_vout: apply_changes failed [ 3.235626] omap_vout: probe of omap_vout failed with error -22 [ 3.242187] omap_vout:Could not register Video driver [ 3.253204] dmm dmm: initialized all PAT entries [ 3.414428] [drm] Enabling DMM ywrap scrolling [ 3.486267] Console: switching to colour frame buffer device 240x67 [ 3.517700] fb0: omapdrm frame buffer device [ 3.522308] drm: registered panic notifier [ 3.526733] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).

I don't see any /dev/video* devices listed as expected.
Another observation is that, I see random kernel oops messages (they are totally random and I don't see them on reboot in some occasions). Here is the log when I see the crash:

I seem to have a similar problem. The 3.4 kernel worked without DSS yesterday, before it was added back again. Now I have added DSS again, which gives internal errors. I get:

I also get a lot of error messages from the omapdss:
[ 43.052581] omapdss DISPC error: SYNC_LOST on channel tv, restarting the output with video overlays disabled
sometimes I get spammed by them, about 10 each second or something. I do get a /dev/video0 with this though, so might not be completely related. Also don't get the /dev/fb0 error, but it seems to be udev crashing.
Best regards Martin

Hi,
With the latest tilt-3.4 branch, I see these messages in the kernel while booting up:
[ 3.176330] twl_rtc twl_rtc: setting system clock to 2000-01-01 00:00:00 UTC (946684800) [ 3.185882] omap_vout omap_vout: 'hdmi' Display already enabled [ 3.192138] omap_vout omap_vout: 'hdmi' Display already enabled [ 3.198425] omap_vout omap_vout: Buffer Size = 3686400 [ 3.204925] omapdss OVERLAY error: check_overlay: paddr cannot be 0 [ 3.211578] omap_vout omap_vout: setup_overlay failed [ 3.216949] omap_vout omap_vout: apply_changes failed [ 3.235626] omap_vout: probe of omap_vout failed with error -22 [ 3.242187] omap_vout:Could not register Video driver [ 3.253204] dmm dmm: initialized all PAT entries [ 3.414428] [drm] Enabling DMM ywrap scrolling [ 3.486267] Console: switching to colour frame buffer device 240x67 [ 3.517700] fb0: omapdrm frame buffer device [ 3.522308] drm: registered panic notifier [ 3.526733] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).

I don't see any /dev/video* devices listed as expected.
Another observation is that, I see random kernel oops messages (they are totally random and I don't see them on reboot in some occasions). Here is the log when I see the crash:

On 06/27/12 20:44, the mail apparently from Martin Ertsås included:
I seem to have a similar problem. The 3.4 kernel worked without DSS
[ 5.351684] LR is at sysfs_write_file+0x178/0x1a8
If you look back in your dmesg, does all this start with that same error about paddr being 0 that ramakrishnan found?
I also get a lot of error messages from the omapdss:
[ 43.052581] omapdss DISPC error: SYNC_LOST on channel tv, restarting the output with video overlays disabled
sometimes I get spammed by them, about 10 each second or something. I do get a /dev/video0 with this though, so might not be completely related. Also don't get the /dev/fb0 error, but it seems to be udev crashing.
udev likes to go and fondle everyone's sys node, if the device represented by the node is incorrectly instantiated it can blow these kind of chunks.
Typically it didn't get instantiated correctly because it realized something was busted, and the error path did not clean up the sys registraton. It suggests if you study your dmesg closer you can get a clue about the issue that all this is stemming from.

Yes, that is the start of it. Looks like everything is fine untill:

And then stuff is failing, this is also something I always get.

This is actually fixed by the attached patch[1]; it was acked for 3.3+, but somehow got missed in the pull request.
Could you please use this and let us know if everything's ok for you?
Thanks and regards, ~Sumit.

The patch applied fine on tilt-3.4. When I bootup I get these messages:

Now, if I do the following:
# gst-launch videotestsrc ! v4l2sink
I get a message:

and the gstreamer pipeline fails.
I will be glad to give you any other debug traces to fix the problem.

I think perhaps because I built all these v4l2 and vout pieces as modules, I get different behaviour. Maybe I am missing a driver needed or it doesn't work so well done as modules.

Could you try to setup a dss pipeline manually via sysfs and see? (need to connect overlay0->tv(as manager)->hdmi(panel) via sysfs).
Unfortunately, the OMAP display team here is not actively working on or supporting V4L2 display driver interface, so the support might be a little sporadic.

well, i don't think any of us is doing that either as we switch to omapdrm only.

Thanks.
The patch applied fine on tilt-3.4. When I bootup I get these messages:
[...] [ 3.180572] omap_vout omap_vout: 'hdmi' Display already enabled [ 3.186859] omap_vout omap_vout: 'hdmi' Display already enabled [ 3.193145] omap_vout omap_vout: Buffer Size = 3686400 [ 3.199645] omap_vout omap_vout: : registered and initialized video device 0 [ 3.207122] omap_vout omap_vout: Buffer Size = 3686400 [ 3.213562] omap_vout omap_vout: : registered and initialized video device 1 [...]
Now, if I do the following:
# gst-launch videotestsrc ! v4l2sink
I get a message:
[ 352.257080] omap_vout omap_vout: Unable to apply changes
and the gstreamer pipeline fails.
I will be glad to give you any other debug traces to fix the problem.
Ok; could you please add "omapdss.debug=1 debug" in your bootargs and share the logs you get from this?
Thanks Ramakrishnan
BR, ~Sumit.

Hi Ramakrishnan,
+Vaibhav from TI (another team), who's the maintainer for omap_vout. He has kindly agreed to look into these issues.
Best regards, ~Sumit.

Ramakrishnan,
Just wanted to clarify before it turns out to be some sort of commitment, I will be working on this depending on my bandwidth availability.
Just FYI, I wanted to work on this since long time now, and hopefully should be able to get some time in next week. I will keep you posted...
Thanks, Vaibhav

Ramakrishnan,
Just wanted to clarify before it turns out to be some sort of commitment, I will be working on this depending on my bandwidth availability.
Just FYI, I wanted to work on this since long time now, and hopefully should be able to get some time in next week. I will keep you posted...
Thanks, Vaibhav

Ramakrishnan,
Just wanted to clarify before it turns out to be some sort of commitment,

Ramakrishnan,
I do not see any role of VOUT driver here, Are you doing anything on v4l2 driver? Can you disable the V4L2 driver from your config and try? I am sure you will see get same boot log, except related to VOUT driver.
Thanks, Vaibhav

I see the above message even without doing anything with V4L2 display driver. If I disable VOUT driver (OMAP V4L2 Display driver) from the kernel configuration, then I do not see the omapdss DISPC error messages anymore.

Thanks for the info. I think that's where the patch from Archit is playing Role, comes into picture during probe.
I will look into this.

...it all seems pretty nice.
I don't see any /dev/video* devices listed as expected.
Another observation is that, I see random kernel oops messages (they are totally random and I don't see them on reboot in some occasions). Here is the log when I see the crash:
Like it says these are warnings
[ 4.535278] WARNING: at fs/sysfs/file.c:343
sysfs_open_file+0x7c/0x238()
they are not OOPSes or crashes.
Error opening /dev/fb0: No such file or directory Starting udev [ 4.311767] udevd (797): /proc/797/oom_adj is deprecated, please use /proc/797/oom_score_adj instead.

This is meant to tell the name of the kobject which has no attribute operations, apparently ''. I guess udev touched everything in sight and provoked this warning, possibly as a consequence of the first problem about paddr being 0 killing registration of something. But the warning itself isn't fatal.

I doubt it's the source of the problem but you shouldn't need any of that stuff about vram, omapfb, omapdss.
