config VGA_ARB
bool "VGA Arbitration" if EMBEDDED
default y
depends on PCI
help
Some "legacy" VGA devices implemented on PCI typically have the same
hard-decoded addresses as they did on ISA. When multiple PCI devices
are accessed at same time they need some kind of coordination. Please
see Documentation/vgaarbiter.txt for more details. Select this to
enable VGA arbiter.
config VGA_SWITCHEROO
bool "Laptop Hybrid Grapics - GPU switching support"
depends on X86
depends on ACPI
help
Many laptops released in 2008/9/10 have two gpus with a multiplxer
to switch between them. This adds support for dynamic switching when
X isn't running and delayed switching until the next logoff. This
features is called hybrid graphics, ATI PowerXpress, and Nvidia
HybridPower.
