What exactly does irq remapping mean, and what are its benefits in the current Xen VT-D architecture? It's really not at all clear what's going on from the current VT-D documentation. Since all interrupts get abstracted through Xen right now, if it's just an interrupt-line remapping then that doesn't seem very useful... -- Keir On 24/1/08 02:33, "Kay, Allen M" <allen.m.kay@xxxxxxxxx> wrote: > Attached patch remaps interrupt for passthru device if such HW is > detected on VT-d platforms. > > Signed-off-by: Allen Kay <allen.m.kay@xxxxxxxxx> > _______________________________________________ > Xen-devel mailing list > Xen-devel@xxxxxxxxxxxxxxxxxxx > http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
