The problem still occurs on 2.6.36-rc2-00098-gd1b113b (which includes
drm patches from yesterday's pull).

Do you know what specific commit caused the breakage?  Both sets of logs have
the same vbo message.

Alex,
Unfortunately I don't know. I would if I could do bisecting. But due to the
problems I described in the first e-mail I couldn't. So far I've got only what
I had initially: the screenshot and the logs. Maybe there are some other logs
which could give us something more specific? I have searched in my home folder
in the 0 A.D. config and cache files but I can't see anything useful there.

I wonder if anyone else has come across the same issue? Or maybe you would be
able to reproduce it? That involves installing O A.D., unfortunately (I don't
what other software would be good to use as an equivalent for testing this
case).

[originally posted on LKML]

I can't log on to bugzilla again, so replying from here [LKML].

When you start the game please choose single player, default map
(Arcadia) and accept (you can skip the players setup). The bug appears
right away when the map has been loaded and the game begins. On my box
that happens only on kernels 2.6.36-rc[1-3]. On 2.6.35.[0-4] it's OK.

One more thing. I have no support for S3TC compressed textures enabled
in mesa and that turns up a performance warning message. I just accept
it to get to the initial game menu. Lack of S3TC support causes
performance slowdown on both 'good' and 'bad' kernels but this is
rather irrelevant for the case we are testing. What's important is to
keep the same settings within libdrm, mesa etc when running the game
on 2.6.35.x and 2.6.36-rcx

Weird; works fine here (other than the vbo warnings).  Everything renders
correctly.  What version of mesa are you using?

I was finally able to reproduce this.  It's a bug in the mesa development
snapshot you are using.  Upgrade to a newer snapshot or use a released version.
 The drm code is fine.

--- Comment #15 from trapdoor6@gmail.com  2010-08-31 07:35:39 ---
There's no newer snapshot available for my system (Ubuntu Lucid) in that PPA
yet, only for Maverick. The yesterdays snapshot failed to build on Launchpad
for Lucid (i386 and amd64). So I'll wait until the next one shows up, which I'd
expect very soon (and hopefully it will be build successfully on amd64).
I never compiled mesa myself and don't want to do it now, neither revert to
7.8.

But still: on kernel 2.6.35.4, with the same mesa version the game runs fine,
no empty black squares at all.. I understand it's that bug in mesa which
affects only 2.6.36-rc. And the bug is triggered by some recent drm-radeon
commit in kernel, but there is nothing wrong with that commit itself..

I'll test again when a new mesa snapshot is available and let you know the
outcome right away.

Thanks a lot for looking into this.

It's sort of random luck.  The vbo size was getting garbage values.  You'll
also note that the vbo size errors in your kernel log are gone with a newer
mesa snapshot.

There was at least one drm pull between 2.6.36-rc2 and -rc3. So I
tested on -rc3 and I confirm that the issue is still present.

I was going to update the bugzilla entry but it won't let me log in at
this moment.

I can't log on to bugzilla again, so replying from here.

When you start the game please choose single player, default map
(Arcadia) and accept (you can skip the players setup). The bug appears
right away when the map has been loaded and the game begins. On my box
that happens only on kernels 2.6.36-rc[1-3]. On 2.6.35.[0-4] it's OK.

One more thing. I have no support for S3TC compressed textures enabled
in mesa and that turns up a performance warning message. I just accept
it to get to the initial game menu. Lack of S3TC support causes
performance slowdown on both 'good' and 'bad' kernels but this is
rather irrelevant for the case we are testing. What's important is to
keep the same settings within libdrm, mesa etc when running the game
on 2.6.35.x and 2.6.36-rcx
