BSP Developer’s Guide, 6.0

bar0 in 32-bit mem space @ 0x80002000

[0,18,0] type=P2P BRIDGE to [1,0,0]

base/limit:

mem= 0x80100000/0x800fffff

preMem=0x0000000090000000/0x000000008fffffff

I/O= 0x00000000/0x00000fff

status=0x02b0 ( CAP 66MHZ FBTB DEVSEL=1 )

command=0x0007 ( IO_ENABLE MEM_ENABLE MASTER_ENABLE )

value = 0 = 0x0

This example uses a wrPpmc440gp board and BSP, with a USB adapter plugged

into a PCI slot. The host bridge, [0,0,0] is shown twice. This is intentional. The USB

2.0 card contains three devices, all listed as serial devices. The board also contains

a bridge at [0,18,0], connecting to bus 1.

pciDeviceShow( )

The pciDeviceShow( ) routine displays concise information about all of the

function zero devices on a given bus. No attempt is made to convert vendor ID,

device ID, or class into readable format.

The following example, using the same hardware as the previous example, shows

that there are three devices on bus 0 and none on bus 1.

Scanning function 0 of each PCI device on bus 0 Using configuration mechanism

00000000 00000012 00000000 00008086 0000b154 00060400

value = 0 = 0x0

-> pciDeviceShow (1)

Scanning function 0 of each PCI device on bus 1 Using configuration mechanism

bus device function vendorID deviceID class

value = 0 = 0x0

Note that pciDeviceShow( ) only displays information about devices configured

as function 0. In this example, the second and third devices on the USB adapter do

not show up because they are at function 1 and function 2.

pciHeaderShow( )

The pciHeaderShow( ) routine displays the full PCI configuration space header for

the device at the specified [bus, device, function] tuple. The routine understands

both bridged and non-bridged devices.
