[Qemu-devel] [RFC 12/12] pc: Generate APIC IDs according to CPU topology

This keeps compatibility on machine-types pc-1.2 and older, and prints a warning in case the requested configuration won't get the correct topology. I couldn't think of a better way to warn about broken topology when in compat mode other than using error_report(). The warning message will be proba

[Qemu-devel] [RFC 02/12] target-i386: Don't set any KVM flag by default if KVM is disabled

This is a cleanup that tries to solve two small issues: - We don't need a separate kvm_pv_eoi_features variable just to keep a constant calculated at compile-time, and this style would require adding a separate variable (that's declared twice because of the CONFIG_KVM ifdef) for each fea

[Qemu-devel] [RFC 03/12] pc: Reverse pc_init_pci() compatibility logic

Currently, the pc-1.4 machine init function enables PV EOI and then calls the pc-1.2 machine init function. The problem with this approach is that now we can't enable any compatibility code inside the pc-1.2 init function because it would enable the compatibility behavior on pc-1.3 and pc-1.4 as we

[Qemu-devel] [RFC 05/12] target-i386: kvm: Set vcpu_id to APIC ID instead of CPU index

The CPU ID in KVM is supposed to be the APIC ID, so change the KVM_CREATE_VCPU call to match it. The current behavior didn't break anything yet because today the APIC ID is assumed to be equal to the CPU index, but this won't be true in the future. Signed-off-by: Eduardo Habkost --- Cc: k...@vger
