config IA64_GRANULE_16MB
bool "16MB"
help
IA-64 identity-mapped regions use a large page size called "granules".
Select "16MB" for a small granule size.
Select "64MB" for a large granule size. This is the current default.

config IA64_PRINT_HAZARDS
bool "Print possible IA-64 dependency violations to console"
depends on DEBUG_KERNEL
help
Selecting this option prints more information for Illegal Dependency
Faults, that is, for Read-after-Write (RAW), Write-after-Write (WAW),
or Write-after-Read (WAR) violations. This option is ignored if you
are compiling for an Itanium A step processor
(CONFIG_ITANIUM_ASTEP_SPECIFIC). If you're unsure, select Y.
config DISABLE_VHPT
bool "Disable VHPT"
depends on DEBUG_KERNEL
help
The Virtual Hash Page Table (VHPT) enhances virtual address
translation performance. Normally you want the VHPT active but you
can select this option to disable the VHPT for debugging. If you're
unsure, answer N.
config IA64_DEBUG_CMPXCHG
bool "Turn on compare-and-exchange bug checking (slow!)"
depends on DEBUG_KERNEL
help
Selecting this option turns on bug checking for the IA-64
compare-and-exchange instructions. This is slow! Itaniums
from step B3 or later don't have this problem. If you're unsure,
select N.
config IA64_DEBUG_IRQ
bool "Turn on irq debug checks (slow!)"
depends on DEBUG_KERNEL
help
Selecting this option turns on bug checking for the IA-64 irq_save
and restore instructions. It's useful for tracking down spinlock
problems, but slow! If you're unsure, select N.
