[PATCH] nir: Walk blocks in source code order in lower_vars_to_ssa. (11.10 KB, patch) 2016-08-25 04:05 UTC, Matt Turner	Details \| Splinter Review

Description _archuser_ 2016-08-06 12:09:29 UTC

Specific parts of xcom: enemy unknown cause a segfault in i965_dri.so (64bit), last known mesa version to work without segfault was 11.2.2-1 (arch package from Feb 11, if i965_dri.so loaded via LIBGL_DRIVERS_PATH, it still works).
Xcom seems to to some specific things when switching to ingame cinematics (e.g. after first mission transition, some stuff near endgame etc.) and only crashes on these parts , rest of the game seems to work fine.

apitrace / glretrace produce traces that always crash semi-randomly during replay and are unusable for me atm.
Trace shows recursive calls to nir_phi_builder_value_get_block_def ? -> stack overflow causing SEGSEGV ?
Not a C programmer here, took some time to set this up to work at all.

I just made a debug build of the i965_dri driver to load vie LIBGL_DRIVERS_PATH from master/git so I finally had a backtrace at all, any help is appreciated.

If the trace was used to get the backtrace, I suspect it'll be useful to me. Could you post it somewhere?

That looks plausible.

I'm very appreciative!

Comment 2 _archuser_ 2016-08-16 21:53:33 UTC

I created a new trace via the apitrace wrapper library to run while running gdb using latest mesa-git, the new trace and backtrace can be found here (glretrace still crashes randomly on replay though):

Thanks.

I have run this trace in valgrind on my Haswell, master and 12.0.1 and I cannot reproduce same backtrace as you.

However, I do see

    i965/vec4: Ignore swizzle of VGRF for use by var_range_end().


I'll investigate the problem in copy_array_to_vbo_array now.

I've tried Mesa master and 12.0.1 compiled with and without debugging (-O0 -ggdb3) with gcc 4.9.3 and gcc 5.4.0. A co-worker tried on Haswell and Arch, with the default Arch packages, as well as mesa master compiled with gcc 6.1.1. He could only reproduce the same problems I've noted in this comment.

I wouldn't think the problem in copy_array_to_vbo_array was related to the crash you're seeing, but I guess we won't know for sure until it's fixed.

I should also mention that I can reproduce the two problems I noted with Mesa 11.2.2, so they seem unlikely to be the cause of the problem you see.

Another idea, you might try reverting this commit:

    util/ralloc: Remove double zero'ing of rzalloc buffers

It is in the 12.0 branch but not 11.2.

Note that both before and after this patch we should
be (still) zero filling all ralloc'd buffers by using
calloc.

This patch was just removing the additional memset
when rzalloc was used.

Oh, right. That's probably not the culprit then.

I just played the first mission of Enemy Within and got a segfault immediately before the cinematic began. Progress!

Comment 9 Matt Turner 2016-08-24 06:19:14 UTC

After a very painful bisect, I've found this commit to be the culprit:

commit 7d539080c1a491aff9fb3e90c25df89884477aa8
Author: Kenneth Graunke <kenneth@whitecape.org>
Date:   Tue Nov 17 00:26:37 2015 -0800

    nir: Add a writemask to store intrinsics.

Interestingly, it is in 11.2. I found 11.2-branchpoint to be bad and 11.1-branchpoint to be good, and so those were the starting points of my bisection.

Comment 10 Matt Turner 2016-08-24 21:28:08 UTC

I've got a fix.

Comment 11 Matt Turner 2016-08-25 04:05:02 UTC

Patch on the list:

   [PATCH] nir: Walk blocks in source code order in lower_vars_to_ssa.

Comment 12 Matt Turner 2016-08-25 04:05:35 UTC

Created attachment 126028 [details] [review]
[PATCH] nir: Walk blocks in source code order in lower_vars_to_ssa.

Comment 13 Matt Turner 2016-08-25 20:45:13 UTC

Thanks again for the great bug report. I've pushed the fix as

commit e53130cc27b966a09d48be53cb51e09ea7ad0649
Author: Matt Turner <mattst88@gmail.com>
Date:   Wed Aug 24 19:25:58 2016 -0700

    nir: Walk blocks in source code order in lower_vars_to_ssa.

and tagged it for the stable branch, so it should be available in 11.2.3 and 12.0.2.
