Bug ID: 99354
Summary: [G71] "Assertion `bkref' failed" reproducible with
glmark2
Product: Mesa
Version: 13.0

OS: Linux (All)

glmark2 backtrace
[G71] "Assertion `bkref' failed" reproducible with glmark2
Using glmark2 I can trigger the assertion
"glmark2: pushbuf.c:238: pushbuf_krel: Assertion `bkref' failed."
quite easily. I'm not sure if this is a duplicate of other bugs.
The fastest way to reproduce seems to be:
./glmark2 -b
buffer:columns=200:interleave=false:update-dispersion=0.99:update-fraction=0.5:update-method=subdata:buffer-usage=static
--run-forever
Changing some parameters from that command line still trigger the assertion,
but usually it takes a bit more time. The command above triggers for me
after 2.5 seconds (usually less than that), while for example the following
command
./glmark2 -b
buffer:columns=200:interleave=false:update-dispersion=0.9:update-fraction=0.5:update-method=map
--run-forever
can trigger even a minute later.
I've used glmark2 at commit f413c5b423250b4fde8f95639ad368d5b02c5b9b.
Software versions:
xf86-video-nouveau-1.0.13
mesa-13.0.3
libdrm-2.4.74
xorg-server-1.19.0
Hardware: nVidia Quadro FX 1500
Backtrace attached.

glmark2 apitrace
This is an apitrace of glmark2 hitting th bkref assertion. I've used apitrace
at commit 849af14927410b5cd8a9597a39bd7f636ae54644.

Does running the apitrace in question cause the assert to happen?

Cool thanks! I think a similar issue has been reported before, and I stared at
that code with little success. Having a reproducible issue that I can poke at
should definitely make success (in at least understanding, if not fixing) much
more likely.

While I was not able to hit the issue by replaying your trace, I grabbed
glmark2, and with
MESA_GL_VERSION_OVERRIDE=2.0 ./build/src/glmark2 -b
buffer:columns=200:interleave=false:update-dispersion=0.99:update-fraction=0.5:update-method=subdata:buffer-usage=static
(built with the x11-gl target) it indeed fails on my NV34. Will start digging.

I have been unable to trigger the issue locally with the following mesa patch:
https://patchwork.freedesktop.org/patch/132414/
Please try to see if this also resolves your problems.

I've applied your patch on top of mesa 13.0.3 (there was a conflict in
nvc0_query_hw.c, but it doesn't matter with my hardware).
I've been running
gdb --args ./glmark2 -b
buffer:columns=200:interleave=false:update-dispersion=0.99:update-fraction=0.5:update-method=subdata:buffer-usage=static
--run-forever
for 30 minutes now, so I guess this issue is fixed.
Thank you, Ilia.
Changing status to resolved-fixed.
