2019-12-17x86: move more x86-generic functions out of PC filesPaolo Bonzini
These are needed by microvm too, so move them outside of PC-specific files. With this patch, microvm.c need not include pc.h anymore. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-08-16Include hw/qdev-properties.h lessMarkus Armbruster
In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

2019-08-16Include hw/irq.h a lot lessMarkus Armbruster
In my "build everything" tree, changing hw/irq.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/hw.h supposedly includes it for convenience. Several other headers include it just to get qemu_irq and.or qemu_irq_handler. Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to qemu/typedefs.h, and then include hw/irq.h only where it's still needed. Touching it now recompiles only some 500 objects.

2018-06-28ioapic: support "info irq"Peter Xu
This include both userspace and in-kernel ioapic. Note that the numbers can be inaccurate for kvm-ioapic. One reason is the same with kvm-i8259, that when irqfd is used, irqs can be delivered all inside kernel without our notice. Meanwhile, kvm-ioapic is specially treated when irq numbers <ISA_NUM_IRQS, those irqs will be delivered in kernel too via kvm-i8259 (please refer to kvm_pc_gsi_handler).

2017-02-16kvm/ioapic: dump real object instead of a fake onePeter Xu
When we do "info ioapic" for kvm ioapic, we were building up a temporary ioapic object. Let's fetch the real one and update correspond to the real object as well. This fixes printing uninitialized version field in ioapic_print_redtbl().

2013-07-01KVM: PIC: Only commit irq routing when necessaryAlexander Graf
The current logic updates KVM's view of our interrupt map every time we change it. While this is nice and bullet proof, it slows things down badly for me. QEMU spends about 3 seconds on every start telling KVM what news it has on its routing maps. Instead, let's just synchronize the whole irq routing map as a whole when we're done constructing it. For things that change during runtime, we can still update the routing table on demand. Signed-off-by: Alexander Graf <agraf@suse.de>
