[Xen-devel] Genapic in 32-bit Dom0 (Was : More Problems booting32-bit Domain 0 on ES7000 x86_64) |
Ooops that could cause problems for us on the ES7000 x86_64 as we run in
clustered apic mode. With a uniprocessor Dom0 I see that it picks up
clustered apic. From a cursory look at the genapic code in Dom0 I don't
see a difference between UP and SMP clustered_apic_check(). Am I looking
at the wrong place?
Thanks
