an unimplemented feature

I sent patches to mail list too.

still cannot work.
Is the SDVO-TV detected in UMS mode?
If so, please attach the output of xorg.log, vbios dump.
Because our latest driver has latest tv detection patch,
haien, could you please update and test it again

I have tested it with the latest kernel. and it still fails.
but UMS works well.
what I means is that TV isn't detected in KMS.I think anything about TV should show in dmesg. after start X, I cann't see any TV information in the Xorg.0.log and there is no display on TV-screen. but with the same card, X can start normally with UMS.
ma ling said UMS has this problem as well. updated the summary line.
After updating UMS code from our master tree, the issue also will occur, randomly the sdvo tv device is disconnect. The sdvo device care shows not reliable.
The symptom is the same with bug #20785 please try the patch

The patch from http://bugs.freedesktop.org/attachment.cgi?id=26795 works fine, so could you try it on the issue again?
thanks for your help
Let's track KMS issue (can't detect SDVO-TV) here, and track UMS issue (SDVO-TV connection unreliable) in bug#20785.
