properly check for _DSM function support and Optimus support for vga_switcheroo
...eyn/acpi-stuff/tree/master/bbswitch). This adds
a proper
check whether a _DSM function is supported or not and make OFF / ON for
vga_switcheroo work for nVidia Optimus models. The patch is based against
the
mainline kernel.
It has been tested on my Clevo B7130 laptop running kernel 3.2 which has a
GT425M

lockdep splat while exiting PRIME
Hi,
While trying PRIME, I got a lockdep warning after exiting glxgears. Is
it harmful? The command was:
DRI_PRIME=1 glxgears
Offload provider is a GT425M (NVC0), output sink is an Intel i5-460M.
Kind regards,
Peter
