SPARC Hypervisor/LDom is *code* that runs in the Hyper-Privileged execution mode, which was introduced in the sun4v architecture. You can get the specification of the sun4v architecture at OpenSPARC. (I did not study the Hyper-Privileged execution mode in detail, but I assume it is very similar to the AMD-V or IVT... it's basically a "ring -1" mode.) (BTW, I wrote the "Logical Domains" wikipedia page early last year, but unless the architecture of LDom changed a lot, it should still be valid) Some useful stuff: 1) Logical Domains (LDoms) http://opensolaris.org/os/community/ldoms/files/LDoms-LOSUG-Oct-2007.pdf 2) Hyperprivileged Mode http://www.opensparc.net/opensparc-t2/index.html http://opensparc-t1.sunsource.net/index.html Rayson > > > -- > This message posted from opensolaris.org > _______________________________________________ > dtrace-discuss mailing list > [email protected] > _______________________________________________ dtrace-discuss mailing list [email protected]
