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.

Reserves space in the kernel to maintain resource locking for

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