This is awesome ! A LOT of HTPC fans are waiting for this! Is there a
chance that this lands in 3.2 ?
Thanks, Alan

Thanks for finishing this up. The mode list was indeed mechanically
generated (pdf2text on the spec and then some python to bash it all
together). It's probably worth noting in the comment that it's from
CEA-861-D, as I suspect subsequent revisions have added more timings (I
haven't bought it yet to check).

I ran a test with the CEA patch, on my Sandy Bridge system with a Samsung
HDTV hooked up with an Onkyo TX-SR-607 AV-receiver.
The patch works like charm. The so wanted missing modelines are there, both
in the kernel log and in the Xorg.log and I can now use them in any Media
Center application,

Thanks for the great work!!! Would be awesome if somehow this could sneak
into the final 3.2. If not, users won't be using this unti Ubuntu 12.11 !
In one year.
Just as a sidenote: There is fully Xorg issue I think. Independently from
this patch. Xorg makes some strange DDC cheked modelines, where the
modeline is correct, but it does not contain the refresh rate, It is just
zeroed out. Is it normal ?

Works fine here on top of Linus’ 7f80850d3f9f with a Radeon HD 4290 and
an hdmi-connected tv.

Any news on when this will be in master ?

Dave, Christian has a few patches outstanding for CEA mode handling.
Getting them in makes sense to me and this patch looks like it's
structured nicely at least (I haven't checked the CEA bits against the
specs though).
Any chance we can get them included for 3.3?
Thanks,

I've put this patch in, but please (and reviewers too, please tell
people before acking) in future,
submit patches as per the kernel's Documentation/SubmittingPatches
This patch was attached instead of inlined, wasn't in git format (not
essential but less work for me so more patches for you).
Is there other patches outstanding if so? please resend with collected reviews.
really anything that involves me taking manual steps will generally
mean I'll just drop the patch without caring with the understanding
that whoever wants the patch merged will care more than I do.
Dave.

Hi,
Looking over this i noticed that this patch adds an incomplete list of video
modes.
For many of the short descriptors, two modes should be added. One for a integer
refreshrate and one for the old ntsc rate (rate*1000/1001).
Would be nice to see that resolved since it's rather crucial to get right for
video playback.

Shameless bump on the subject. Would be nice if we could
get this list complete when connecting to HDTV's.

Yea, it would be nice.
UK bluray seems to use 24/1.001 - not that it's that bad watching with
TV@24Hz.
I do have issues with interlaced modes on my TV. I don't know how DRM
handles interlaced, but CEA says that the number of vblank lines
alternates per field. If that isn't happening then I guess that's why.

If this is on an intel gpu, you need kernel 3.4 to make interlaced work.
If that doesn't help, please file a bug on bugs.freedesktop.org.

Thanks, but it's AMD I do have a bug open for it.

Which reminds me - another issue with CEA modes is that the ones that
should be double clocked are not.
