Summary: kernel support for power management of nVidia GPU on Optimus enabled laptops.
Description:
bbswitch is a kernel module which automatically detects the required ACPI calls for two kinds of Optimus laptops. It has been verified to work with "real" Optimus and "legacy" Optimus laptops (at least, that is how I call them). The machines on which these tests has performed are: - Clevo B7130 - GT 425M ("real" Optimus, Lekensteyns laptop) - Dell Vostro 3500 - GT 310M ("legacy" Optimus, Samsagax' laptop) (note: there is no need to add more supported laptops here as the universal calls should work for every laptop model supporting either Optimus calls) It's preferred over manually hacking with the acpi_call module because it can detect the correct handle preceding _DSM and has some built-in safeguards.
