Description
PUMLIM: Prefetchable Upper 32-bit Memory Limit Address
Corresponds to A[63:32] of the memory address that maps to the upper limit of
the prefetchable range of memory accesses that will be passed by the PCI
Express bridge. OS should program these bits based on the available physical
limits of the system.
IOB[7:2] - I/O Base Register (Upper 16 bits)
Not used since MCH does not support upper 16-bit I/O addressing.
IOL[7:2] - I/O Limit Register (Upper 16 bits)
Not used since MCH does not support upper 16-bit I/O addressing.
CAPPTR[7:2, 0]- Capability Pointer
The CAPPTR is used to point to a linked list of additional capabilities implemented by
this device.
It provides the offset to the first set of capabilities registers located in the PCI
compatible space from 40h. Currently the first structure is located 50h to provide room
for other registers.
