           Summary: Missing background graphics/texture in frogatto with
                    R600 (RV670)
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: crazy-ivanovic@gmx.net

scene1, hardware accelerated, broken background

I have a problem with the background texture as used in frogatto (a
sidescrolling jump&run). The problem can be seen in the attached screenshots
frogatto_texture-prob1.jpg and frogatto_texture-prob2.jpg. The expected result
can be observed in frogatto_software-mode_scene1.jpg and
frogatto_software-mode_scene2.jpg (created using the software renderer via
LIBGL_ALWAYS_SOFTWARE=1). My graphics card is a generic HD3850 (RV670) with
512MB ram.

To reproduce this issues you will first have to get frogatto and build it
yourself, to do so do the following steps:
0) get the build dependencies, I am not sure about those. From the flags used
in the command I'd assume these: 
- libsdl
- sdl-image
- sdl-ttf
- sdl-mixer (probably with vorbis support)
- boost-{regex, system, thread, iostreams}
- x11
- mesa (GL and GLU required)
- glew
1) get the svn checkout eg using "svn checkout
http://frogatto.googlecode.com/svn/trunk/ frogatto-read-only"
2) cd frogatto-read-only
3) edit "Makefile" and remove every occurence of "-lprofiler" (seems to break
building due to whatever reason, not fixed yet for upstream, but this way it is
possible to compile+run it)
4) compile using "make"
5) run the resulting binary by typing "./game" (controls are the arrow keys
plus 'a' and 's', exit the game by pushing 'esc')

After step 5) you should see the missing background texture when using the git
version of mesa (currently as of today 7.8-devel). There is no problem when
using the software renderer and there is also no problem on a system with an
Intel i945 based chip and mesa 7.7 or mesa 7.6. I don't know if it ever worked
for r6xx hardware with mesa.
Someone yesterday mentioned in #radeon that s3tc is broken on r600. I don't
know if s3tc is used, but I don't think so. Is there some easy way to check
this in the sources?

Here is the software stack used:
Gentoo unstable (arch: amd64)
mesa, xf86-video-radeon and libdrm from git-master
KMS active
kernel 2.6.33-rc7

shadowmaster (another Wesnoth dev) just told me that he has the same problems
with frogatto. Here some info about his system:
01:05.0 VGA compatible controller: ATI Technologies Inc RS780M/RS780MN [Radeon
HD 3200 Graphics]
Linux 2.6.32.5 on Debian Squeeze
running Mesa 7.7 (release)
lastest-ish drm from the git repository
latest-ish ddx from the radeon repository
no KMS

So it looks like it does not depend on KMS and that the issue is no regression
(since it does already exist in 7.7).

To make sure to get a version that does compile and link, please use this
checkout link:
svn checkout -r 1712 http://frogatto.googlecode.com/svn/trunk/
frogatto-read-only

You still have to update the Makefile, this sed command does the job:
sed -i "s/ -lprofiler//g" Makefile

Frogatto started working after revision 1713

r1713: Integrated the rectangle rotation code into the blitting routines to
actually be used when an object is to be rotated.

So this bug can be caused by broken blitting on r600.

Sounds like an app bug if it's fixed in a newer version of the app.  The r600
driver in mesa 7.6 and 7.7 doesn't accelerate CopyTex(Sub)Image (which is what
the 'blit' code in the r600 driver does), only mesa master does.

--- Comment #13 from Nils Kneuper <crazy-ivanovic@gmx.net>  2010-02-09 14:16:24 PST ---
Okay, some updates.
1) As testcase you can also use rev1715. In this one there is no change to the
makefile required. If you got the libs, you should be able to compile things
with a simple "make". Yes, in >=r1713 basically all textures "vanished".


2) In IRC, talking with agd5f and Jetrel (one of the people working on
frogatto) we found the reason for those missing textures. Here is the
respective part from the logs of #radeon:

[22:47:36] <agd5f> Ivanovic, stikonas: does it work any better/worse with mesa
7.7 branch?
[22:51:40] <Ivanovic> agd5f: no visible difference for me in frogatto r1712
[22:51:58] <Ivanovic> agd5f: that with both, git master and mesa 7.7 (release
version) it looks identical
[22:52:08] <agd5f> Ivanovic: ok.  so probably not the blit code
[22:52:51] <agd5f> Ivanovic: if you use non-float values for vertex attributes
that may be a problem
[23:09:07] <Ivanovic> agd5f: just talked to jetrel (he is online in irc, though
he tends to not join too many chans...), he said that they intentionally use
shorts for the vertex attributes since this is just the precision required
[23:09:21] <Ivanovic> agd5f: this should explain the reason for the problems,
right?
[23:09:54] <Ivanovic> the reason for this is the reduced memory bandwidth
compared to using floats
[23:09:56] <agd5f> Ivanovic: yes.  they are broken right now in git
[23:10:48] <Ivanovic> okay
[23:11:15] <Ivanovic> agd5f: want me to add this as comment to the bugreport or
will you take care of it? (that is: i would just paste this part of the
changelog)
[23:12:19] <agd5f> Ivanovic: yes please

The patch solves the problem here with a Radeon HD 3200 (RS780M/RS780MN)
controller on Debian Squeeze (amd64, custom Linux 2.6.32.5 build, no KMS,
latest radeon ddx and libdrm from the git repos). All textures were previously
missing with the same latest build of the application, using both Mesa 7.7 and
later HEAD from the git master (before applying the patch, that is).
