unvanquished.log

Without AA everything looks good. Atfer turn on antialliasing both games crash
with log:

EE r600_texture.c:326 r600_texture_get_fmask_info - Got error in surface_init
while allocating FMASK

and 

"_name_of_process_":dri2.c:547: dri2_allocate_textures: Assertion

i've tried this with xf86-video-ati and it looks like the problem is in
modesetting ddx. 
With radeon AA works fine. 

Should i fill new bug in xorg/modesetting thread?

Somebody needs to track down why radeon_surface_init returns a non-0 value. I
think it most likely comes from si_surface_sanity, but I'm not sure.

For now, let's assume this is a radeonsi driver bug.

Please check your kernel version and if it is outdated test with at least 3.19

Igor, i use 1-day old git/svn for mesa/llvm/kenel except for xf86-video-ati, i
don't use it at all. If your distribution use xorg-1.17.x you may try
xf86-video-modesetting. It would be really nice if you can. As I wrote before,
for xf86-video-ati the problem doesn't exist ...at least for me.

Could you tell which version of radeon ddx failed for unvanquished + AA.

somewhere between mesa 10.2.x & 10.3

I've tested some tags of mesa with: llvm-3.5.1 & xorg 1.17.1+modesetting &
drm_next.

1)mesa 10.2.9 - looks ok
2)mesa 10.3.(0,1)&10.4.4 - looks like a crap (see pic) but not fails (play
music,  can screen shot, can escape with ALT+F4)
3)mesa dev-10.(5,6) - crashes

between stage 2&3 the winner is:

3da735cc4c478b0ab2ecc2164899cf9d77dc671a is the first bad commit
commit 3da735cc4c478b0ab2ecc2164899cf9d77dc671a
Author: Jason Ekstrand <jason.ekstrand@intel.com>
Date:   Sat Aug 23 10:45:00 2014 -0700

    main: Add a concept of an array format

    An array format is a 32-bit integer format identifier that can represent
    any format that can be represented as an array of standard GL datatypes.
    Whie the MESA_FORMAT enums provide several of these, they don't account for
    all of them.

    v2 by Iago Toral Quiroga <itoral@igalia.com>:
     - Implement mesa_array_format as a plain bitfiled uint32_t type instead of
       using a struct inside a union to access the various components packed in
       it. This is necessary to support bigendian properly, as pointed out by
       Ian.
     - Squashed: Make float types normalized

    v3 by Iago Toral Quiroga <itoral@igalia.com>:
      - Include compiler.h in formats.h, which is necessary to build in MSVC as
        indicated by Brian Paul.

 modesetting in dri2 mode is fine here :). Probably, but do you use xserver's
modesetting driver in dri3 mode?

 There are whole bunch of piglit crashes and gpu lockups here with anything
dri3 related - be it with xserver's modeseting or radeon ddx (i tried this
patched radeon https://github.com/iXit/xf86-video-ati/commits/master and it
suffer from the same issues like modesetting)

Is there any way to switch dri mode? As far i know xorg1.17+modesseting just
uses dri3. There is no log with dmesg/xorg/systemd when dri3 is used. 
So answer for your question is: so probably yes, but i don't know for sure. 

DDX from https://github.com/iXit/xf86-video-ati/ has the same symptoms like
modeseting but looks worse a lot (this is why i never like it)

I've just tried new mesa/master and it doesn't crash anymore. Problem goes back
to stage 2 (see pics), but:
-----
EE r600_texture.c:326 r600_texture_get_fmask_info - Got error in surface_init
while allocating FMASK.
-----
is still present. 

Probably is like smoki said, dri3 is problem here and if there's no official
support for dri3, should we really care about it for now?
