Parameter irq_bus

Type Text string

Value

When specified, the "irq_bus" configuration parameter specifies virtual bus routing interrupt requests from virtual PCI adapter to CHARON-AXP virtual Alpha CPUs.

By default the "irq_bus" configuration parameter is not specified.

The "irq_bus" configuration parameter must be set to “isa” for AlphaServer 400. For HP Alpha systems other than AlphaServer 400 the "irq_bus" configuration parameter must be left as is (i.e. not specified).

Example:

load KZPBA PKA irq_bus=isa

irq

Parameter irq

Type Numeric

Value

When specified, the "irq" configuration parameter assigns interrupt request to the virtual PCI adapter in HP Alpha system.

By default the irq configuration parameter is not specified.

If the irq configuration parameter is not specified, the CHARON VM software uses the correct values depending on the selected PCI position of a virtual PCI adapter.

Example:

load KZPBA PKA irq=24

The IRQ stands for input line of ASIC interrupt controllers. It has nothing to do with "EISA" style interrupts. So far, the CHARON-AXP VMs do not emulate NCR 53C810 PCI SCSI adapter. Instead, emulation of QLOGIC ISP1040B PCI SCSI adapter is used.
