--pci
Valid Argument Read-only
Description
Performs a scan of all PCI buses and displays the results. This utility uses an open source pci.ids
le for vendor or device name resolution. This utility looks for a le called pci.ids in the current
working directory. If the le is not found in the current working directory, the directory containing
the CCTK executable is searched. If the -n option is used to specify a lename, this lename is
used for resolution. If a specic lename is not given and the pci.ids le cannot be found,
Unknown is printed for all vendor and device codes. For more information, see Completion Code.
NOTE: You can download the latest pci.ids le from pciids.sourceforge.net.
Example (the pci.ids lename
is specied in the command
line instance)
C:\>cctk --pci -n <location_of_pci.ids>

--pcibuscount
Valid Argument
64, 128, 256
Description Sets the maximum PCI bus count for the system.
--pciersa
Valid Argument
enable, disable
Description
Enables or disables the Reliability Availability Serviceability (RSA) support on PCIe devices.
--pcimmiospacesize
Valid Argument
small, large
Description Allocates a part of the memory to the PCI Memory Mapped I/O. It allows you to reserve large or
small device-specic memory regions to decrease or increase the usable memory on systems with
a 32-bit operating system.
• small — Allocates a small region of memory to PCI memory mapped I/O.
• large — Allocates a large region of memory to PCI memory mapped I/O. This reserves the
large device specic memory regions, but reduces the amount of usable memory in 32-bit
operating system.
