Description Jaroslav Šmíd 2009-08-31 11:27:34 UTC

Description of problem:
720p resolution is not detected for TV using HDMI output. More info in upstream bugreport (https://bugs.freedesktop.org/show_bug.cgi?id=23098)

There is already a solution for that problem, but the patch they provided me with seem to be for 2.6.32 version of linux kernel, although I managed to get it applied for 2.6.31rc8, but I had to apply it on top of other patches (also mentioned in upstream bugreport).

What I want is to ask you if those patches could be included in next Fedora release (12). I created patch composed all of those in original bugreport or you could use those patches one by one. They doesn't seem to break things, they just "fix" modes detection based on EDID. I think they could be safely included.

Thanks.

The fedora kernel already has a large part of the upstream code for 2.6.32 applied. Here are the results of trying to apply your patch:

My patch is for vanilla 2.6.31rc8, I suppose you applied it on patched kernel (?). I'll download fedora's src.rpm for 2.6.31 and make new patch.

Comment 4 Jaroslav Šmíd 2009-09-01 11:35:11 UTC

I can see that most of the patch is really already included in fedora's rpm (in drm-next.patch). Only this (http://www.mail-archive.com/dri-devel@lists.sourceforge.net/msg42703.html) part is not there.

Comment 7 Michal Schmidt 2009-09-14 06:14:13 UTC

Jaroslav,
Your proposed patch seems to be already included in the Fedora kernel as a part of drm-next.patch since:
* Tue Sep 08 2009 Dave Airlie <airlied> 2.6.31-0.206.rc9.git1
- drm: rebase to drm-next - r600 accel + kms should start working now

I am closing this bug. Please reopen if you can still reproduce the problem.

Comment 8 Jaroslav Šmíd 2009-09-14 11:13:09 UTC

Ok, thanks.
