MSI

The GPIC supports memory mapping only. At boot-up the internal registers

space is mapped to memory space. The device driver can disable memory space

through the PCI Configuration Command register.

MSI:

MSI is forced low to indicate that the internal registers map into memory

space.

TYPE[1:0]:

The TYPE field indicates where the internal registers can be mapped. The

encoding 00B indicates the registers may be located anywhere in the 32 bit

address space, 01B indicates that the registers must be mapped below 1

Meg in memory space, 10B indicates the base register is 64 bits and the

encoding 11B is reserved.

The TYPE field is set to 00B to indicate that the CBI registers can be mapped

anywhere in the 32 bit address space.

PRFTCH:

The Prefetchable (PRFTCH) bit is set if there are no side effects on reads

and data is returned on all the lanes regardless of the byte enables.

Otherwise the bit is cleared. TSBs contain registers, such as interrupt status

registers, in which bits are cleared on a read. If the PCI Host is caching data

there is a possibility an interrupt status could be lost if data is prefetched, but

the cache is flushed and the data is not used. The PRFTCH bit is forced low

to indicate that prefetching of data is not supported for internal registers.
