KVM: change the way how lowest priority vcpu is calculated

2009-06-10T08:48:27+00:00

The new way does not require additional loop over vcpus to calculate
the one with lowest priority as one is chosen during delivery bitmap
construction.

KVM: consolidate ioapic/ipi interrupt delivery logic

2009-06-10T08:48:27+00:00

Use kvm_apic_match_dest() in kvm_get_intr_delivery_bitmask() instead
of duplicating the same code. Use kvm_get_intr_delivery_bitmask() in
apic_send_ipi() to figure out ipi destination instead of reimplementing
the logic.

KVM: ioapic/msi interrupt delivery consolidation

2009-06-10T08:48:27+00:00

ioapic_deliver() and kvm_set_msi() have code duplication. Move
the code into ioapic_deliver_entry() function and call it from
both places.

KVM: Merge kvm_ioapic_get_delivery_bitmask into kvm_get_intr_delivery_bitmask

2009-06-10T08:48:26+00:00

Gleb fixed bitmap ops usage in kvm_ioapic_get_delivery_bitmask.

Sheng merged two functions, as well as fixed several issues in
kvm_get_intr_delivery_bitmask
1. deliver_bitmask is a bitmap rather than a unsigned long intereger.
2. Lowest priority target bitmap wrong calculated by mistake.
3. Prevent potential NULL reference.
4. Declaration in include/kvm_host.h caused powerpc compilation warning.
5. Add warning for guest broadcast interrupt with lowest priority delivery mode.
6. Removed duplicate bitmap clean up in caller of kvm_get_intr_delivery_bitmask.

KVM: Update intr delivery func to accept unsigned long* bitmap

2009-06-10T08:48:22+00:00

Would be used with bit ops, and would be easily extended if KVM_MAX_VCPUS is
increased.

2009-06-10T08:48:22+00:00

In order to use with bit ops.

KVM: Split IOAPIC structure

KVM: Report IRQ injection status to userspace.

2009-03-24T09:03:11+00:00

IRQ injection status is either -1 (if there was no CPU found
that should except the interrupt because IRQ was masked or
ioapic was misconfigured or ...) or >= 0 in that case the
number indicates to how many CPUs interrupt was injected.
If the value is 0 it means that the interrupt was coalesced
and probably should be reinjected.

KVM: Export ioapic_get_delivery_bitmask

2008-12-31T14:55:01+00:00

It would be used for MSI in device assignment, for MSI dispatch.
