Select "16MB" for a small granule size. Select "64MB" for a large granule size. This is the current default. config IA64_GRANULE_64MB bool "64MB" depends on BROKEN endchoice 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 && PRINTK 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.
