Description
Indicates compliance with version 1.1 of PM.
There are no other extended capabilities.
Indicates this is power management data structure.
Power State
*This register is read/write if configuration management is enabled
(pci_setup[1]). If not enabled, it is read only.
Bits [31:24] of IO address during PCI IO transactions.
Bits [23:16] of IO address during PCI IO transactions.
Use “upper_io3_addr” as the upper address for PCI IO transactions.
Use “upper_io3_addr” and “upper_io2_addr” as the upper address
for PCI IO transactions.
1: PCI_Base2 will forward PCI2 DTL transactions to PCI bus as IO
transactions. The address will unchanged or modified with an
alternate upper addresses selected above.
0: PCI_Base2 will forward PCI2 DTL transactions to PCI bus as
memory transactions with unchanged address.
PCI slave DTL read block size for memory read command. Default
value is 8 32-bit words. Maximum is 64 32-bit words.
Threshold (amount of data not consumed from previous read
request) for when PCI slave DTL requests more read data when
responding to memory read command. This must be set to a value
less than the smallest of slv_memrd_fetch, Cache Line Size or
read_block_siz. Default is 3 32-bit words. Maximum value is 32 32-
bit words.
