Description Md Imam Hossain 2011-06-25 04:01:42 UTC

commit

i965: Use state streaming on programs, and state base address on gen5+.
http://cgit.freedesktop.org/mesa/mesa/commit/?id=c173541d9769d41a85cc899bc49699a3587df4bf

causes gpu hang.

try to run any game like http://maniadrive.raydium.org/ or GPU caps viewer with WINE except glxgears.

anyway, off topic - why Linux Intel driver is so slow :(

System:

Ubuntu 10.10
Linux 2.6.38-02063807-generic
libdrm 2.4.24
Xserver 1.9.3
xf86-video-intel 2.14.0

Hmm, if that commit is truly to blame (which at first glance it should be because gen4 is excluded from the changes), then it is likely to have left a tell-tale in /sys/kernel/debug/dri/0/i915_error_state.
