The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

|
|
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.

help
|
|
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.
