For what it's worth, I get the EINVAL error even on the stock Fedora 20 kernel on Haswell (and presumably IvyBridge) so I can only assume the software checker is already upstream, unless I'm misunderstanding something. $ uname -r 3.16.7-200.fc20.x86_64 $ modinfo i915 | grep cmd_parser parm: enable_cmd_parser:Enable command parsing [...] (1=enabled [default], 0=disabled) (int) $ sudo cat /sys/module/i915/parameters/enable_cmd_parser 1 If I cat 0 to /sys/module/i915/parameters/enable_cmd_parser then I no longer get the EINVAL error. - Neil _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
