            Bug ID: 91231
           Summary: [NV92] Psychonauts (native) segfaults on start when
                    DRI3 enabled

trace generated by apitrace

The game runs natively on Linux. When Mesa was compiled with DRI3 support the
game segfaults when starting and I get this in the terminal:
Psychonauts: nv50/nv50_miptree.c:132: nv50_mt_choose_storage_type: Assertion
`ms == 0' failed.
The game starts properly if I disable DRI3 at runtime (LIBGL_DRI3_DISABLE=1)

The problem is present since

commit 241e7289f25a342a457952b9b0e539c2f0b81d99
Author: Maarten Lankhorst <maarten.lankhorst-GeWIH/nMZzLQT0dZR+AlfA@public.gmane.org>
Date:   Wed Oct 22 11:04:16 2014 +0200

    enable dri3 support without glamor

When replaying the trace with glretrace the message about the assertion is not
present, but glretrace segfaults with signal 11.

The assertion is regarding PIPE_BIND_SCANOUT + nr_samples != 0. I suspect this
might be a dri st bug which only surfaces with the new mechanisms that dri3
enables.

If you have a Steam account and Steam for Linux installed you can reproduce the
segfault with these native Linux demos on Steam:
- 'Running with Rifles' demo (note: I had to remove libstdc++.so.6 and
libxcb.so.1 from ./lib).
- Torchlight II demo (the game starts with default settings, you need to enable
anti-aliasing in-game option and restart the game to reproduce this bug).

All those games crash on start with
>nv50/nv50_miptree.c:132: nv50_mt_choose_storage_type: Assertion `ms == 0' failed.
when DRI3 is enabled.

The patch works and fixes the problem in all the affected games that I know of.
Thank you both for your help fixing this bug.
