This patch set brings back functionality which was broken in v4.0.
Unfortunately because of restrictions of such a hardware is is impossible
to take advantage of virtual architected timer, therefore guest, running
in such restricted mode, has to use some memory-mapped timer. But it is
still better
Makes qemu working again with kernel-irqchip=off option, allowing to use
GIC emulation in userspace.
Previously kvm_vgic_map_resources() used to include irqchip_in_kernel()
check, and vgic_v2_map_resources() still has it, but now vm_ops are not
initialized before kvm_vgic_create(). Therefore
Now at least ARM is able to determine whether the machine has
virtualization support for irqchip or not at runtime. Obviously,
irqfd requires irqchip.

Before commit 662d9715840aef44dcb573b0f9fab9e8319c868a is was possible to
compile the kernel without vGIC and vTimer support. Commit message says
about possibility to detect vGIC support in runtine, but this has never
been implemented.
This patch introdices runtime check, restoring the lost
Hi,
I'm trying to install KVM on the latest version of Debian (so Debian 8)
and it's not working. It always gives me a dependencies error. But when
I install it on Debian 7.8, it works no problem. I was wondering if you
would have any solution for me.

When userland wants to inject a MSI into the guest, we have to use

Use the wrapper functions to iterate the linked lists and find the

The guest can use KVM_USER_EXIT instead of a signal-based exiting to

Only x86 is implemented so far.
