This provides the required user space stubs to enable the in-kernel i8254 emulation of KVM. The in-kernel model supports lost tick compensation according to the "delay" policy. This is enabled by default and can be switched off via a device property. Depending on the feature set of the host kernel (before 2.6.32), we may have to disable the HPET or lack sound output from the PC speaker.

This patch switches pc s3 suspend over to the new infrastructure. The cmos_s3 qemu_irq is killed, the new notifier is used instead. The xen hack goes away with that too, the hypercall can simply be done in a notifier function now. This patch also makes the guest actually stay suspended instead of leaving suspend instantly, so it is useful for more than just testing whenever the suspend/resume cycle actually works.

When the HPET enters legacy mode, the IRQ output of the PIT is suppressed and replaced by the HPET timer 0. But the current code to emulate this was broken in many ways. It reset the PIT state after re-enabling, it worked against a stale static PIT structure, and it did not properly saved/restored the IRQ output mask in the PIT vmstate. This patch solves the PIT IRQ control in a different way. On x86, it both redirects the PIT IRQ to the HPET, just like the RTC. But it also keeps the control line from the HPET to the PIT. This allows to disable the PIT QEMU timer when it is not needed. The PIT's view on the control line state is now saved in the same format that qemu-kvm is already using. Note that, in contrast to the suppressed RTC IRQ line, we do not need to save/restore the PIT line state in the HPET. As we trigger a PIT IRQ update via the control line, the line state is reconstructed on mode switch.

HPET legacy emulation will require control over the PIT IRQ output. To enable this, add support for an alternative IRQ output object to the PIT factory function. If the isa_irq number is < 0, this object will be used. This also removes the IRQ number property from the PIT class as we now use a generic GPIO output pin that is connected by the factory function.

This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This introduces the alternative APIC device which makes use of KVM's in-kernel device model. External NMI injection via LINT1 is emulated by checking the current state of the in-kernel APIC, only injecting a NMI into the VCPU if LINT1 is unmasked and configured to DM_NMI. MSI is not yet supported, so we disable this when the in-kernel model is in use. CC: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com>

Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: NAvi Kivity <avi@redhat.com>

qemu-kvm passes numa/SRAT topology information for smp_cpus to SeaBIOS. However SeaBIOS always expects to setup max_cpus number of SRAT cpu entries (MaxCountCPUs variable in build_srat function of Seabios). When qemu-kvm runs with smp_cpus != max_cpus (e.g. -smp 2,maxcpus=4), Seabios will mistakenly use memory SRAT info for setting up CPU SRAT entries for the offline CPUs. Wrong SRAT memory entries are also created. This breaks NUMA in a guest. Fix by setting up SRAT info for max_cpus in qemu-kvm.

apic id returned to guest kernel in ebx for cpuid(function=1) depends on CPUX86State->cpuid_apic_id which gets populated after the cpuid information is cached in the host kernel. This results in broken CPU topology in guest. Fix this by setting cpuid_apic_id before cpuid information is passed to the host kernel. This is done by moving the setting of cpuid_apic_id to cpu_x86_init() where it will work for both KVM as well as TCG modes.

The master PIC is connected to the LINTIN0 of the APICs. As the APIC currently does not track the state of that line, we have to ask the PIC to reinject its IRQ after the CPU picked up an event from the APIC. This introduces pic_get_output to read the master PIC IRQ line state without changing it. The APIC uses this function to decide if a PIC IRQ should be reinjected on apic_update_irq. This reflects better how the real hardware works. The patch fixes some failures of the kvm unit tests apic and eventinj by allowing to enable the proper CPU IRQ deassertion when the guest masks some pending IRQs at PIC level.

The current implementation of PAM and the PCI holes is broken in several ways: - PCI BARs are not restricted to the PCI hole (a BAR may hide memory) - PCI devices do not respect PAM (if a PCI device maps a region while PAM maps the region to RAM, the request will be honored) This patch fixes things by introducing a pci address space, and using memory region aliases to represent PAM regions, SMRAM, and PCI holes. The memory hierarchy looks something like system_memory | +--- low memory alias (0-0xe0000000) | | | +-- ram@0 | +--- high memory alias (0x100000000-EOM) | | | +-- ram@0xe0000000 | +--- pci hole alias (end of low memory-0x100000000) | | | +-- pci@end-of-low-memory | | +--- pam[n] (0xc0000-0xc3fff etc) (when set to pci, priority 1) | | | +-- pci@0xc4000 etc | +--- smram (0xa0000-0xbffff) (when set to pci/vga, priority 1) | +-- pci@0xa0000 etc ram (simple ram region) pci | +--- BARn | +--- VGA 0xa0000-0xbffff | +--- ROMs Signed-off-by: NAvi Kivity <avi@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

We've always listened on port 501 for vgabios panic messages. In the entire time I've worked on QEMU, I've never actually seen a vgabios panic message :-) If we change the semantics of this port a little bit, it makes it possible to use it for more interesting use-cases. I chose this approach instead of adding a new I/O port because it avoids having a guest visible change. This change allows single-byte access to port 501 and also uses the value written to construct an exit code. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
