- bool "Kprobes"
- depends on DEBUG_KERNEL
- help
- Kprobes allows you to trap at almost any kernel address and
- execute a callback function. register_kprobe() establishes
- a probepoint and specifies the callback. Kprobes is useful
- for kernel debugging, non-intrusive instrumentation and testing.
- If in doubt, say "N".

- 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.

- 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.

- 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.

- bool "Turn on compare-and-exchange bug checking (slow!)"
- depends on DEBUG_KERNEL

- Selecting this option turns on bug checking for the IA-64
- compare-and-exchange instructions. This is slow! Itaniums

- select N.
- config IA64_DEBUG_IRQ
- bool "Turn on irq debug checks (slow!)"
- depends on DEBUG_KERNEL

- Selecting this option turns on bug checking for the IA-64 irq_save

- problems, but slow! If you're unsure, select N.
