Thread-topic: [Xen-devel][PATCH][RESEND]Add broadcast destination for physical destinationmode in LAPIC virtualization code
User-agent: Microsoft-Entourage/11.2.5.060620
Actually I looked closer and you always make yourself look like a P4/Xeon APIC. So the correct phys broadcast id is always 0xFF for the virtual LAPIC. You shouldn’t check for 0xF. Right?

Do you need to support 0xF as broadcast dest? Are there VT chips that have a P6-style APIC? I’m just a little concerned that we may eventually use 0xF as an APIC ID, when we run VT guests with enough VCPUs. We could avoid that though.
