Hi, Here is a patch (on top of the paravirt patch queue) which makes xen guests use the hvc_console.c infrastructure for the console, thereby greatly reducing the amount console code. xvc0 is gone too, hvc0 is used instead. cheers, Gerd -- Gerd Hoffmann <kraxel@suse.de>

Hi, Anyone has this working? Looks like there is a chicken-and-egg issue with pda setup: * xen_load_gdt() uses multicalls, thus depends on cpu-specific variables (per-cpu mc buffer) which in turn requires pda being setup already. * pda setup can't be done before xen_load_gdt() ... Next question while looking at xen_load_gdt(): why does it use multicalls in the first place?
