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 SPARC T4 servers and Fujitsu M10 servers.
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 servers, SPARC M5 servers, and SPARC M6 servers must run at least version 9.1.0.x of the system firmware.
SPARC T7 series servers and SPARC M7 series servers must run at least version 9.4.3 of the system firmware.
Fujitsu M10 servers must run at least version XCP2210 of the system firmware.
Non-primary domains must run at least the Oracle Solaris 11.2 OS.
