Hi,
I have been using nouveau on my laptop (with GeForce GT 540M card) for a
while, and it's been working quite well! Now I am trying to connect my
TV using HDMI port, but wasn't so lucky with that. I would like to know
the current status of HDMI out support for GF108 (NVC1). I am trying
with the latest code from nouveau/master tree (2fee6f5).
When I connect the tv, it's not getting detected by the laptop. I see a
small change in brightness of the laptop screen for a moment and nothing
else. Usually there is nothing in the dmesg as well, but once I saw the
below line.
[ 249.780634] nouveau E[ PDISP][0000:01:00.0] chid 1 mthd 0x0080 data
0x00000000 0x000b5080
But when I removed the HDMI cable, I got the below log.

I tried several times, each time with similar logs when the cable is
plugged out.

I am trying to figure out from code, but any help would be greatly
appreciated! I can post the full logs or .config file if required.
Thanks in advance,
