Each peripheral device of CHARON Virtual Machine (VM) connects to CHARON-AXP emulated PCI bus with the following configuration parameters:

bus

Format

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 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 software connects the virtual PCI adapter to the first available virtual PCI bus.

Example (AlphaServer ES40):

load KZPBA PKA bus=pci_1

Example (AlphaServer GS80):

load KZPBA PKA bus=qbb_1_pca_1_pci_0

Parameter	bus
Type	Text string
Value	Value formats:	Models

device

Parameter device

Type Numeric

Value

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.

Example:

load KZPBA PKA device=2

function

Parameter function

Type Numeric

Value

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 at the first available position of the virtual PCI bus.

Example:

load KZPBA PKA function=0

irq_bus

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

Div

class	pagebreak

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

Note that typically all or some of those parameters are specified on loading of some PCI controller in the following way:

The IRQ stands for bit position in DRIR of Tsunami/Typhoon chip. It has nothing to do with “ISA” style interrupts which are routed to IRQ 55 (including ALi M1543C PCI IDE/ATAPI controller).

...

In addition to 10 PCI vacant slots there are 3 PCI positions occupied by on-board devices. All 13 PCI positions are listed in the following table in the order in which Alpha SRM console enumerates them.
