Revision 713d25dba93ec3e739e209cd13bf7e1e9b00171a authored by Linus Torvalds on 28 March 2015, 17:58:53 UTC, committed by Linus Torvalds on 28 March 2015, 17:58:53 UTC
Pull parsic fixes from Helge Deller: "One patch from Mikulas fixes a bug on parisc by artifically incrementing the counter in pmd_free when the kernel tries to free the preallocated pmd. Other than that we now prevent that syscalls gets added without incrementing __NR_Linux_syscalls and fix the initial pmd setup code if a default page size greater than 4k has been selected" * 'parisc-4.0-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Fix pmd code to depend on PT_NLEVELS value, not on CONFIG_64BIT parisc: mm: don't count preallocated pmds parisc: Add compile-time check when adding new syscalls
Kconfig
config VGA_ARB
bool "VGA Arbitration" if EXPERT
default y
depends on (PCI && !S390)
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_ARB_MAX_GPUS
int "Maximum number of GPUs"
default 16
depends on VGA_ARB
help
Reserves space in the kernel to maintain resource locking for
multiple GPUS. The overhead for each GPU is very small.
config VGA_SWITCHEROO
bool "Laptop Hybrid Graphics - GPU switching support"
depends on X86
depends on ACPI
select VGA_ARB
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.
