Chapter 3 Programming

MVME6100

The MVME6100 IPMC module PCI arbitration is performed by the MV64360 ASIC. The internal PCI arbiter REQ#/GNT# signals are multiplexed on the MV64360 MPP[31:0] pins. The internal PCI arbiter is disabled by default (the MPP pins function as general purpose inputs). Software will configure the MPP pins to function as request/grant pairs for the internal PCI arbiter.

The IPMC module arbitration pairs for the MVME6100 are assigned to the MPP pins as follows;

■MPP pin 8, PCI Bus Grant (PIB device on IPMC module)

■MPP pin 9, PCI Bus Request (PIB device on IPMC module)

■MPP pin 12, PCI Bus Grant (SCSI device on IPMC module)

■MPP pin 13, PCI Bus Request (SCSI device on IPMC module)

Interrupt Assignments

The interrupt architecture for the IPMC712 and IPMC761 is fully compliant with the PowerPlusII Programming Specification for a single processor board configuration.

MVME5100 IPMC Module Interrupt Assignments

Legacy interrupt assignment for the PCI-to-ISA Bridge (PIB) is maintained to ensure software compatibility between MVME5100 and IPMC761 while in IPMC mode. This is accomplished by using the on-board IPMC761 connector to route the PIB’s interrupt to external interrupt 0 of the Hawk’s MPIC.

The MVME5100 Ethernet port 2 is routed to the PIB’s IRQ10 input. The SCSI interrupt on the IPMC761 is also routed to the PIB at IRQ14. The SCSI device is connected to the INTA# pin J11-04 of PMC Slot 1. Interrupts are routed to the Hawk from on-board resources as specified by the module’s programming.

The Hawk interrupt assignments are shown below:

Table 3-6. Hawk MPIC Interrupt Assignments

MPICI	Edge/Leve			Note
RQ	l	Polarity	Interrupt Source	s
IRQ0	Level	High	PIB (8259) in PMC Slot 1	1

IRQ9	Level	Low	SCSI Controller interrupt shall be connected to	2
			INTA# pin J11-04

Notes

1. This interrupt provided for software compatibility with MVME2700.
