When 'injecting' an edge-triggered interrupt with a falling edge we
shouldn't clear the pending state on the distributor. In fact, we
don't, because the check in vgic_validate_injection would prevent us
from ever reaching this bit of code.
Remove the unreachable snippet.

Don't set virtio 1.0 yet, since that requires ANY_LAYOUT

Userspace is expecting non-compacted format for KVM_GET_XSAVE, but

The first patch ensures that XSAVES is not exposed in the guest until
we emulate MSR_IA32_XSS. The second exports XSAVE data in the correct
format.
I tested these on a non-XSAVES system so they should not be completely

Hi,
I was wondering whether it is possible to use blktap2 or blktap3 (from
the tools of Xen) as the block devices for KVM?
Both blktap2 and blktap3 are the tools from Xen as the block devices.
They are all outside of Xen. According to the blktap3 wiki page,
blktap3 even does not require any kerne

The IOEVENTFD KVM capability is a prerequisite for vhost support,
and is also used to implement improved interrupt handling in VFIO drivers.
This series enables the ioeventfd KVM capability on ARM.
The implementation routes MMIO access in the IO abort handler to the KVM IO bus.
If there is alread
In io_mem_abort remove the call to vgic_handle_mmio. The target is to have
a single MMIO handling path - that is through the kvm_io_bus_ API.
Register a kvm_io_device in kvm_vgic_init on the whole vGIC MMIO region.
Both read and write calls are redirected to vgic_io_dev_access where
kvm_exit_mmio
KVM on arm will support the eventfd extension.

This is needed in e.g. ARM vGIC emulation, where the MMIO handling
depends on the VCPU that does the access.

On IO memory abort, try to handle the MMIO access thorugh the KVM
registered read/write callbacks. This is done by invoking the relevant
kvm_io_bus_* API.
