9 Kprobes allows you to trap at almost any kernel address and
10 execute a callback function. register_kprobe() establishes
11 a probepoint and specifies the callback. Kprobes is useful
12 for kernel debugging, non-intrusive instrumentation and testing.

23 IA-64 identity-mapped regions use a large page size called "granules".
25 Select "16MB" for a small granule size.
26 Select "64MB" for a large granule size. This is the current default.

36 depends on DEBUG_KERNEL
38 Selecting this option prints more information for Illegal Dependency
39 Faults, that is, for Read-after-Write (RAW), Write-after-Write (WAW),
40 or Write-after-Read (WAR) violations. This option is ignored if you
41 are compiling for an Itanium A step processor
42 (CONFIG_ITANIUM_ASTEP_SPECIFIC). If you're unsure, select Y.

48 The Virtual Hash Page Table (VHPT) enhances virtual address
49 translation performance. Normally you want the VHPT active but you
50 can select this option to disable the VHPT for debugging. If you're

54 bool "Turn on compare-and-exchange bug checking (slow!)"
55 depends on DEBUG_KERNEL
57 Selecting this option turns on bug checking for the IA-64
58 compare-and-exchange instructions. This is slow! Itaniums
59 from step B3 or later don't have this problem. If you're unsure,
63 bool "Turn on irq debug checks (slow!)"
64 depends on DEBUG_KERNEL
66 Selecting this option turns on bug checking for the IA-64 irq_save
67 and restore instructions. It's useful for tracking down spinlock
68 problems, but slow! If you're unsure, select N.
