<pre>Several Steam games crash since this commit:
67aef6dafa29fed008ea6065c425a6a92a651be9
winsys/radeon: if there's VRAM-only usage, keep it
author: Marek Olšák
Games which crash:
- Left 4 Dead 2: GPU lockup after 15-20 seconds of gameplay. If I set the gfx
details lower, I can play more before a lockup (60 seconds I would say).
- Metro Last Light: GPU lockup
- Serious Sam 3: segfault
What I call a "GPU lockup":
- game freezes
- sound freeze and repeat
- screen is dark
- screen then go in "Out of range" mode
- I need to hard reboot
Games which doesn't crash:
- Half-Life² Episode Two
- Team Fortress 2
- Counter Strike Source
- Unigine Heaven
- Unigine Valley
Hardware:
AMD CYPRESS (HD5850 with 1GB VRAM)
I can also test with RV770 if necessary.
Software:
Fedora 19 x86-64
kernel 3.13.5-101.fc19.x86_64
libdrm 2.4.50
Build:
./autogen.sh --with-gallium-drivers=r600 --with-dri-drivers=
--enable-texture-float --disable-dri3 --disable-r600-llvm-compiler
--disable-gallium-llvm --enable-32-bit CFLAGS="-O2 -m32 -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64" CXXFLAGS="-O2 -m32" --libdir=/usr/lib</pre>
