IOBAR - I/O Base Address
B/D/F/Type:
Address Offset:
Default Value:
Access:
Size:
This register provides the Base offset of the I/O registers within Device #2. Bits 15:3
are programmable allowing the I/O Base to be located anywhere in 16bit I/O Address
Space. Bits 2:1 are fixed and return zero, bit 0 is hardwired to a one indicating that 8
bytes of I/O space are decoded. Access to the 8Bs of IO space is allowed in PM state
D0 when IO Enable (PCICMD bit 0) set. Access is disallowed in PM states D1-D3 or if
IO Enable is clear or if Device #2 is turned off or if Internal graphics is disabled.
Note that access to this IO BAR is independent of VGA functionality within Device #2.
Also note that this mechanism is available only through function 0 of Device#2 and is
not duplicated in function #1.
If accesses to this IO bar is allowed then the CPU Uncore claims all 8, 16 or 32 bit IO
cycles from the CPU that falls within the 8B claimed.

Memory Base Address (MBA):
Set by the OS, these bits correspond to address
signals [31:19].
Address Mask (ADM):
Hardwired to 0s to indicate 512 KB address
range.
Prefetchable Memory (PREFMEM):
Hardwired to 0 to prevent prefetching.
Memory Type (MEMTYP):
Memory / IO Space (MIOS):
Reserved ():
Read as "0", these bits correspond to address
signals [31:16].
IO Base Address (IOBASE):
Set by the OS, these bits correspond to
address signals [15:3].
Memory Type (MEMTYPE):
Hardwired to 0s to indicate 32-bit address.
Memory/IO Space (MIOS):
Hardwired to "1" to indicate IO space.
Hardwired to 0s to indicate 32-bit address.
Hardwired to 0 to indicate memory space.
