Parameter bus

Type Text string

Value

Value formats:

Models	Format
AlphaServer 400-4100, DS, ES	"pci_<X>"
AlphaServer GS	"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-AXP 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 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 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 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

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-AXP 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:

load KZPBA PKA bus=pci_1 device=1 function=0 irq_bus=isa irq=24

0	0	11	0	10	<option>
1	0	12	0	15	<option>
2	0	13	0	9	<option>

The IRQ stands for ISA IRQ Number because all interrupts are routed through the Intel i82378 PCI ISA Bridge (SATURN) resident cascade of Intel i8259 interrupt controllers.

...

No support for Multi-Function PCI devices in AlphaServer 400.

Example: Loading Loading DE435 into slot 0

load DE435/dec21x4x EWA bus=pci_0 device=11 function=0 irq_bus=isa

The The "irq_bus=isa" setting is setting is specific to AlphaServer 400 only.

The IRQ stands for input line of ASIC interrupt controllers. It has nothing to do with "EISA" style interrupts. So far, the CHARON-AXP emulators do not emulate S3 Trio32/64 Display Adapter. So position of the device 6, function 0 on the PCI 0 remains empty.

Example 1: Loading DE500BA into slot 0

load DE500BA/dec21x4x EWA bus=pci_0 device=11 function=0

load DE500BA/dec21x4x EWB EWD bus=pci_0 device=14 function=1 load DE500BA/dec21x4x EWC EWE bus=pci_0 1 device=14 function=2 load DE500BA/dec21x4x EWD EWF bus=pci_0 1 device=14 function=3

In the above examples device name is EWC as there are built-in EW-like PCI Ethernet Adapters located “closer” to CPU and therefore assigned names EWA and EWB.

Example 3: Loading mixture of KZPBA and DE500BA into slot 1, populating 2 functions out of 4

load KZPBA PKB bus=pci_0 1 device=14 function=0
load DE500BA/dec21x4x EWC bus=pci_0 device=14 function=1

In the above example device name is EWC as In the above example device name is PKB as there is a built-in PK-like PCI SCSI Adapter located “closer” to CPU and therefore assigned name PKA, as there are two built-in EW-like PCI Ethernet Adapters located “closer” to CPU and therefore assigned names EWA and EWB.
