vp (SDM)

Displays PCI system data.

vp - display subcommand list
vps - scan PCI address space
vps[ima] - scan PCI address space with IRQ/MSI/ADDR info
vph pciaddr - display header for given device
vpr[bwd] pciaddr offset [length] - read from PCI header
vpw[bwd] pciaddr offset value - write to PCI header

PCI addresses are in the form [bus:]device[.func], where the bus:
and .func parts are optional. For example:

0:28.2 refers to bus 0, device 28, function 1
29.1 refers to bus 0 (implied), device 29, function 1
2:0 refers to bus 2, device 0, function 0 (implied)

Subcommands

vp

Displays a list of all subcommands:

PCI commands:
  vps - scan PCI address space
  vps[ima] - scan PCI address space with IRQ/MSI/ADDR info
  vph pciaddr - display header for given device
  vpr[bwd] pciaddr offset [length] - read from PCI header
  vpw[bwd] pciaddr offset value - write to PCI header
  vp - display subcommand list

vps

Scans the PCI bus and displays a line for each function found. Displays the address, vendor and device IDs, and the class ID for each function found.
Example:

Address Vend/Dev class
 00:00.0 8086/0150 0600
 00:02.0 8086/0152 0300

vpsi

Scans the PCI bus and displays a line for each function found, with interrupt and bus information. For each function the header type, interrupt pin and line assignments and capability list are displayed. In the case of a bridge the first and last bus IDs behind the bridge are shown.
Example:
