Module Name:

    vectirql.h

Abstract:

    This module implements machine specific interrupt functions
    for IBM's PowerPC Machines.

    Code in this module was largely gathered from other modules
    in earlier versions of the HAL.

Author:

    Chris Karamatas - Collected VectorToIrql Tables into one file.

Environment:

    Kernel mode.

//
// The following table maps Interrupt Vectors to the appropriate
// IRQL.  The MPIC is initialized to assign vectors 16 thru 31
// to its sources 0 thru 15.   The 8259 gives us vectors 0 thru 15.
//
// It is possible that we are actually dealing with a Hydra, which
// is an MPIC with sources 0 through 19, so we have extra entries
// in the table.
//
// The MPIC is also programmed with priority in ascending order by
// vector (and source).
//
// This table should reflect the real mapping of vector to device
// priority.  This implementation assumes that all MPIC sources
// are at a higher priority than 8259 sources.
