<pre>The given apitrace [1] results in a segmentation fault. I am testing this on a
sony notebook with Intel sandybridge integrated GPU and a dedicated radeon.
1) $ xrandr --setprovideroffloadsink radeon Intel
2) $ DRI_PRIME=1 apitrace replay r600-crash-01.trace
Actual Results: Segmentation Fault
Expected Results: The rendering should work correctly.
I could reproduce this with both the mesa-libGL 10.6.3 as shipped by fedora as
well as mesa 11.0.0-rc1 freshly compiled with:
./configure --enable-selinux --enable-osmesa --enable-egl --disable-gles1
--enable-gles2 --enable-shared-glapi --enable-gbm --enable-glx-tls
--enable-texture-float=yes --enable-gallium-llvm --enable-llvm-shared-libs
--enable-dri --enable-xa --enable-nine
(flags blindly stolen from the Fedora package specification)
intel GPU:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)
radeon GPU:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] (rev ff)
The same trace runs without crash on the Intel.
