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/gpu/vgaarbiter.rst for more details. Select this to
|
|
enable VGA arbiter.

Reserves space in the kernel to maintain resource locking for

multiple GPUS. The overhead for each GPU is very small.

|
Many laptops released in 2008/9/10 have two GPUs with a multiplexer
|
|
to switch between them. This adds support for dynamic switching when
|
|
X isn't running and delayed switching until the next logoff. This
|
|
feature is called hybrid graphics, ATI PowerXpress, and Nvidia
|
|
HybridPower.
