pci io8 addr value
pci io16 addr value
pci io32 addr value
Write a 8-, 16- or 32-bit value to I/O space.
pci scan ?-reg?
Scans all PCI slots for available devices and their current configuration are printed on the terminal. The scan
does not alter the values, however during probing some registers modified by rewritten with the original
value. This command is typically used to look at the reset values (after pci init is called) or for inspecting
how the Operating System has set PCI up (pci init not needed). Note that PCI buses are not enumerated
during scanning, in multi-bus systems secondary buses may therefore not be accessible. If -reg is given the
configured PCI bus is registered into GRMON device handling system similar to pci bus reg, see above.
pci wcfg8 deviceid offset value
pci wcfg16 deviceid offset value
pci wcfg32 deviceid offset value
Write a 8-, 16- or 32-bit value to configuration space. The device ID selects which PCI device/function
is address during the configuration access. The offset must must be located with the device's space and
be aligned to access type. Three formats are allowed to specify the deviceid: 1. bus:slot:func,
2. device name (pdev#), 3. host. It's allowed to skip the bus index, i.e. only specifying slot:func, it
will then default to bus index 0. The ID numbers are specified in hex. If "host" is given the Host Bridge
Controller itself will be queried (if supported by Host Bridge). A device name (for example "pdev0") may
also be used to identify a device found from the info sys command output.
pci wio8 addr value
pci wio16 addr value
pci wio32 addr value
Write a 8-, 16- or 32-bit value to I/O space.
PCI Trace commands:
pci trace
Reports current trace buffer settings and status
pci trace address pattern
Get/set the address pattern register.
pci trace amask pattern
Get/set the address mask register.
pci trace arm
Arms the trace buffer and starts sampling.
pci trace log ?length? ?offset?
Prints the trace buffer data. Offset is relative the trigger point.
pci trace sig pattern
Get/set the signal pattern register.
pci trace smask pattern
Get/set the signal mask register.
pci trace start
Arms the trace buffer and starts sampling.
pci trace state
Prints the state of the PCI bus.
pci trace stop
Stops the trace buffer sampling.
pci trace tcount value
Get/set the number of matching trigger patterns before disarm
pci trace tdelay value
Get/set number of extra cycles to sample after disarm.
RETURN VALUE
Upon successful completion most pci commands have no return value.
The read commands return the read value. The write commands have no return value.
