Non-primary root domains can be used in addition to the control domain to provide direct I/O and SR-IOV capabilities to other domains. This feature is supported starting with the SPARC T4, SPARC M5, and SPARC S7 series server and the Fujitsu M10 server.
In addition to the PCIe cards for the direct I/O and SR-IOV described in https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=REFERENCE&id=1325454.1, other PCIe cards can be used, but not for DIO and SR-IOV. To determine which cards you can use on your platform, see your platform's hardware documentation.
SPARC T4 platforms must run at least version 8.4.0.a of the system firmware.
SPARC T5, SPARC M5, and SPARC M6 servers must run at least version 9.1.0.x of the system firmware.
SPARC T7 and SPARC M7 series servers must run at least version 9.4.3 of the system firmware.
SPARC S7, SPARC T8, and SPARC M8 series servers can run any released version of the system firmware.
Fujitsu M10 servers must run at least version XCP2210 of the system firmware. Fujitsu SPARC M12 servers must run XCP3021 of the system firmware.
Non-primary domains must run at least the Oracle Solaris 11.2 OS.
