Value formats:

• AlphaServer 400-4100, DS, ES, use: "pci_<X>"
• AlphaServer GS, use: "qbb_<X>_pca_<Y>_pci_<Z>"
  

When specified, the bus configuration parameter tells the CHARON-AXP software the virtual PCI PIC bus to which virtual HP Alpha system shall connect a certain virtual PCI adapter.

By default the bus configuration parameter is not specified.

If the bus configuration parameter is not specified, CHARON VM Charon-AXP software connects the virtual PCI adapter to the first available virtual PCI bus.  This is the default.

• AlphaServer 400-4100, DS, ES     use:   "pci_<X>"
• AlphaServer GS                             use:   "qbb_<X>_pca_<Y>_pci_<Z>"
  

Example (AlphaServer ES40):

load KZPBA PKA bus=pci_1

Example (AlphaServer GS80):

load KZPBA PKA bus=qbb_1_pca_1_pci_0

When specified, the device configuration parameter specifies position of a virtual PCI adapter on virtual PCI bus.By default the device configuration parameter is not specified.

If the device configuration parameter is not specified, the CHARON VM software connects the virtual PCI adapter at the first available position of the virtual PCI bus.  This is the default.

Example:

load KZPBA PKA device=2

When specified, the function configuration parameter specifies position of a virtual PCI adapter on virtual PCI bus.By default the function configuration parameter is not specified.

If the function configuration parameter is not specified, the CHARON VM software connects the virtual PCI a dapter adapter at the first available position of the virtual PCI bus. This is the default.

Example:

load KZPBA PKA function=0

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

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.  Thisis the default.

Example:

load KZPBA PKA irq=24
