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 |

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. |

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. |

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.
