Hi, The r300 driver causes a SIGSEV while running nexuiz (http://packages.debian.org/testing/games/nexuiz). This bug is 100% reproduceable by shooting the weapon Mortar (just before the explosion). I discovered that this problem is in r300_dri.so (debian testing package libgl1-mesa-dri) by running nexuiz-sdl in gdb and getting a backtrace after the crash. Find the log below. Then, due to https://bugs.freedesktop.org/show_bug.cgi?id=8348 , I upgraded mesa (incl. dri) to current (2006-11-25) cvs (similar to http://dri.freedesktop.org/wiki/Building). This shows the same effect, except that it tells us that the bug is in r300_state.c:1240 . Find the log below. The contents of Mesa/src/mesa/drivers/dri/r300/r300_state.c are: > 1238 t=r300->state.texture.unit[i].texobj; > 1239 > 1240 if((t->format & 0xffffff00)==0xffffff00) { > 1241 WARN_ONCE("unknown texture format (entry %x) > encountered. Help me !\n", t->format & 0xff); 1242 } Maybe t is assigned a NULL pointer ? Then accessing t->format would segfault. Is mtu wrong ? However, you can probably interpret this better than me. (After I had discovered that bug I found debian bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=391952 and added my information to this bug. There I was requested to report this bug here.)

Hint: One can avoid the crash by setting all graphics details from default to low.
Does this still happen? You might want to provide a little more information; what is enabled or disabled with the settings "high" and "low"? Make sure you test with the latest code from Git.
Here are additional infos about the bug: 0. I have not (yet) tried current mesa git. 1. I upgraded my debian mesa to experimental, which has version 6.5.2-3, including libgl1-mesa-dri-dbg 2. I reproduced the bug with the new versions 3. I included info about nexuiz config 4. I included info about how I ran gdb 5. I included the gdb output, including full backtrace I hope it helps (and you do not get lost in the 400-something lines). ==========================================================================

Ok, next (and probably last) test from my side. Within now I have found out enough about the problem so that I could patch my mesa. So it does not crash nexuiz any more on my machine. Please have a look at it. Here are the details: 1. I upgraded to current (2007-03-10) git again 2. I tested again, same result as before 3. I analyzed some source code: The problem is in function: void r300_setup_textures(GLcontext *ctx) file r300_state.c line 1251 We have a null pointer dereferencation there. This is easy to see from the logfiles I posted. So why do we get this error ? The relevant code is in a loop (l.1241) that iterates over all texture units (0..7). In the next line we have a check if the current texture unit is "enabled" (TMU_ENABLED, l.1242). If so, it is accessed: First the pointer to the texture object is fetched, ("t=r300->state.texture.unit[i].texobj", l.1249), then the status of the texture unit is checked (l.1251). This is where we crash. The reason is that the texture object pointer is a null pointer. Argh. So sometimes we have texture units where the check with TMU_ENABLED says its enabled, but the pointer to the texture object is NULL. I do not know much about the big picture here, but this looks just wrong. Either we should not say the texture unit is enabled when the texture object pointer is NULL, or we should make sure the texture object pointer is not NULL when we say it is enabled. So where does this TMU_ENABLED come from ? It can be found in r300_context.h, line 609. A quick check (mesa/src/mesa/drivers/dri/r300$ grep TMU_ENABLED *.[ch]) tells me that this TMU_ENABLED is only used in our function (r300_setup_textures). Ah, ok. That means there is no special semantics associated with it, it only needs to work here. Let's take a more detailed look at its definition. We find two alternative definitions of TMU_ENABLED in r300_context.h, just above the active one. Both commented out (see lines 604-607). No further info about the reason for these alternative versions is given in the src ;-(. So let's look at the data structures themself. The "main" structure is ctx. The TMU_ENABLED uses "ctx->Texture.Unit[unit]._ReallyEnabled". In our function (r300_setup_textures) we use "r300->state.texture.unit[i].texobj". The "r300" is found via "r300 = R300_CONTEXT(ctx)" (r300_state.c line 1210). R300_CONTEXT(ctx) is found in r300_context.h l.859: "#define R300_CONTEXT(ctx) ((r300ContextPtr)(ctx->DriverCtx))" So we have: ctx->Texture.Unit[unit]._ReallyEnabled vs. ctx->DriverCtx->state.texture.unit[i].texobj Both seem not to be in sync. But I do not know the code close enough to interpret this. But still I can dig a bit further. Where does this "_ReallyEnabled" appear ? ("grep -l _ReallyEnabled *.[ch]" => r300_context.h r300_render.c r300_tex.c r300_texstate.c) The code in r300_tex.c around l.986 seems to need work anyways. (line 984 says "This is incorrect: ..."). Nothing that gives me any clue. The code in r300_texstate.c (function r300UpdateTextureUnit) is more interesting. It seems to do some enabling according to _ReallyEnabled. This makes me guess: maybe a call to r300UpdateTextureUnit would put ctx->Texture.Unit[unit]._ReallyEnabled and ctx->DriverCtx->state.texture.unit[i].texobj in sync (and thus solve our problem) ? So what can I do now ? The simplest thing I can do is to make the definition of TMU_ENABLED more narrow. Another thing I could try is to call r300UpdateTextureUnit before using TMU_ENABLED. 3. Patched and tested: I patched r300_context.h. I replaced #define TMU_ENABLED(ctx, unit) (ctx->Texture.Unit[unit]._ReallyEnabled) with #define TMU_ENABLED(ctx, _unit_) (ctx->Texture.Unit[_unit_]._ReallyEnabled && R300_CONTEXT(ctx) && R300_CONTEXT(ctx)->state.texture.unit[_unit_].texobj) Then I recompiled mesa and did another nexuiz test. And what should I say ? It worked ! However as I am anything but a mesa expert, I am aware that this code maybe only avoids but does not solve the problem. PLEASE, can someone from the mesa team have a closer look at this problem? IMHO I have provided enough information to make it as easy as possible for you to see what is happening. (I will not try calling r300UpdateTextureUnit before using TMU_ENABLED. I think someone who understands mesa should do further examination.) ------------------------------------------------------------------------ logfile of crash with current mesa (without my patch): GNU gdb 6.4.90-debian Copyright (C) 2006 Free Software Foundation, Inc.

Same bug discussed earlier: http://www.mail-archive.com/dri-devel@lists.sourceforge.net/msg28462.html aka http://www.archivesat.com/Direct_Rendering_Open_Source_Project_development/thread1644203.htm
You should attach large log files rather than adding them into the comment because Bugzilla often destroys the formatting of these logs and more importantly it adds a lot of lines to the bug report that people have to wade through.
Created attachment 9750 [details] Backtrace with mesa 6.5.3rc4
Just to let you know, it looks like this still affects 6.5.3rc4. I'm attaching another backtrace (obtained thanks to the debug packages of the Debian X packagers), quite similar, but the formatting should be kept intact, as you requested/suggested. In case some prefers a direct link to a file, it can also be found at http://kibi.sysif.net/pub/logs/nexuiz_r300.backtrace
I have no experience w/ this driver, but maybe something like this will be a work-around: Insert at line 1272 of r300_state.c: if (!t) continue;

Hmmm, I don't see any sign of a TMU_ENABLED macro in the R300 driver (as described in comment #5).
Brian Paul wrote: > Hmmm, I don't see any sign of a TMU_ENABLED macro in the R300 driver (as > described in comment #5). Yes, you are right. I did a new checkout and found it's gone. But your proposed code should have just the same effect.
If you can test my suggestion and report back soon, I'll put it in 6.5.3 which I'm releasing today.
The proposed patch [if (!t) continue;] just works, many thanks. (And sorry for the lag, I don't own the affected HW.)
me too, patch works: it avoids nexuiz crash.
OK, I've commited the work-around for Mesa 6.5.3. I'll leave this bug open until an R300 developer can double-check it.
It has been fixed long time ago and has proved to be working. Closing.
