HDMI-CEC signal lost after restarting TV #39

Closed rkorn86 closed 10 years ago

rkorn86 commented 10 years ago

When my TV is restarted while XBMC is running, the CEC-Signal is not properly restored. My Samsung TV is not finding the XBMC CEC-Device. The same error occours while using the cec test client. Maybe it is only on my Wandboard, but Ive heard from other wandboard users, having the same problem. Is it a wandboard problem? Can it be fixed in the imx6 tree? Any1 else having such a trouble?

PS: Ive fixed the wandboard CEC hardware problem by following this guide: http://www.project-insanity.org/blog/2014/01/24/wandboard-with-hdmi-cec-and-xbmc/ and it is working when I start XBMC or cec-client AFTER I've started the TV till the next TV restart.

It is reminiscent of a report I have read : I will try to reproduce this issue and tell you Can you confirm you really use the latest version I have just forked in this account : https://github.com/xbmc-imx6/libcec ?

Ive just forked the new account and still have the same reproducable error:

^Csignal caught: 2 - exiting

cec-client is not responding anymore. Just a sigkill helps.

Restarting TV while cec-client is waiting for commands results in the same.

EDIT: while cec is loosing signal dmesg shows this output several times:

mxc_hdmi mxc_hdmi: same edid
wolfgar commented 10 years ago

Hmm ok... Thanks for your rapid feedback My first guess is the issue is in the driver. If you compile it as a module, you could try to rmmod it and modprobe it after the TV OFF/ON... If it helps it means that we have to force an new initilization when TV is back

rkorn86 commented 10 years ago

Do you mean the "cdc-acm" module? lsmod is not showing anything releated to cec. Which module do you mean, I should rmmod?

wolfgar commented 10 years ago

No I mean "mxc_hdmi-cec", When I say "if you compile it as a module", I mean you would have to change kernel configuration to build this driver as a module and rebuild kernel + module

rkorn86 commented 10 years ago

Ok, after some trouble with my wandboard ive managed to recompile kernel with mxc_hdmi-cec as module. The problem now is, that I cannot rmmod mxc_hdmi-cec, as it used by 2, while running cec-client

# lsmod 
Module                  Size  Used by
mxc_hdmi_cec            5602  2

killing cec-client lets me rmmod mxc_hdmi_cec, but thats unneeded, as restarting cec-client already brings me the CECTester device back.

forcing rmmod brings the following error:

[  776.700356] Fixing recursive fault but reboot is needed!

PS: a co-worker has absolutely the same problem with is utilite (we both have a Samsung TV, if that matters)

wolfgar commented 10 years ago

OK, sorry I may have missed an important point in your issue report : You mean that only restarting the cec-client was enough to recover a normal behavior after your TV off/on cycle ?

rkorn86 commented 10 years ago

Yep. Restarting xbmc also helps for the xbmc CEC part.

wolfgar commented 10 years ago

OK ! If so, I think I have an idea about the underlying issue : it may be a problem with address discovery at TV restart... I will have a look at this specific part and report

rkorn86 commented 10 years ago

Is there anything I could do, to help solving this issue?

wolfgar commented 10 years ago

Hi,

I have checked the code and I really think my guess about the address discovery to be replayed on TV plug/poweron is an interesting path... Unfortunately, I have not yet tried to implement it to confirm it solves the issue : Sorry time is a sparse resource...

Ohmegas commented 10 years ago

Please see this. The original ticket seem to be lost, but here is a relevant thread: https://github.com/Pulse-Eight/libcec/issues/9

wolfgar commented 10 years ago

The relevant code is in our branch as we are in sync with Gotham beta 3 at this time.. Unfortunately, I have to add a piece of code in the imx implementation and I am ashamed because I have not found the time to get committed to this task. But I have not forgotten and will do it as soon as possible ...

wolfgar commented 10 years ago

This week I worked to improve CEC Especially the driver has been improved (settled blocking cases, issue with cec clock solved, detection of HPD etc), a few improvements of libcec have also been merged (especially issue with physical address) Unfortunately, this issue is still there I fear and I am not so clear about its root cause at the moment...

wolfgar commented 10 years ago

A last update : In fact everything works fine : I wrote the above message after a test which failed but I made a error during it. Please merge urgently this kernel patch https://github.com/wolfgar/utilite/commit/5403341d8e35384a4efb4c5a6a00d023c6b668b6 and everything will be fine

wolfgar commented 10 years ago

Issue solved, Check this comment for required patches...
