Direct I/O Function for the PCI
Expansion Unit
For XCP 2044 or later of SPARC M10-1/M10-4 and for XCP 2050 or later of SPARC
M10-4S, the direct I/O function of Oracle VM Server for SPARC is supported for the
PCI expansion unit. This makes it possible to assign an I/O domain for each slot of
the PCI expansion unit. For details on the direct I/O function of Oracle VM Server for
SPARC, see Oracle VM Server for SPARC Administration Guide for the version used.
If the PCI expansion unit is connected to SPARC M10-4, make the setting below
before using the direct I/O function. For SPARC M10-1, the setting below need not be
made. The direct I/O function can be used simply by connecting the PCI expansion
unit to SPARC M10-1.

Setting/displaying the direct I/O function

To set the direct I/O function for the PCI expansion unit, use the setpciboxdio(8)
command of the XSCF firmware. To confirm the present settings, use the
showpciboxdio(8) command.
For details on the setpciboxdio(8) and showpciboxdio(8) commands, see Fujitsu
M10/SPARC M10 Systems XSCF Reference Manual or the manual page for each
command.
