| Thread-topic: | [RFC] Genapic in x86_64 Dom0 |
I am working on a patch on to accommodate clustered APICs in x86_64 Dom0/U Genapic. At the moment it defaults to flat. I am thinking of splitting genapic_xen into genapic_xen_flat and genapic_xen_cluster. My question is that since the most of the code that checks for clustered vs flat has been IFDEFed out what is the best way to inform the Dom that it needs to run in clustered/flat APIC mode? Should I be thinking about introducing a new hypercall that does this or is there another standard way by which information is passed between Xen and Domains during boot that I can make use of? Thanks Aravindh _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
