This may be overkill for a project as small as the unit tests now but
perhaps it pays to be explicit?

Arguably all of uart0_init() is unnecessary, as we're pretty sure
that the address we initialize uart0_base to is correct. We go
through the motions of finding the uart anyway though, because it's
easy. It's also easy to check chosen/stdout-path first, so let's do
that too. But, just to make all th

What does this memory barrier pair with? I don't think it's necessary.

Hi,
during IOMMU API function testing on s390 I hit the following scenario:
After binding a device to vfio-pci, the user completes the VFIO_SET_IOMMU
ioctl and stops, see the sample C program below. Now the device is manually
removed via "echo 1 > /sys/bus/pci/devices/.../remove".
Although the S
This patch adds a call to __iommu_detach_device() to the
iommu_group_remove_device() function, which will trigger a missing
detach_dev callback in (at least) the following scenario:
When a user completes the VFIO_SET_IOMMU ioctl for a vfio-pci device,
and the corresponding device is removed therea

Yes! This is definitely right. Thi
First patch in a series which enables the relocation of the
PIC/IOAPIC to userspace.
Adds capability KVM_CAP_SPLIT_IRQCHIP;
KVM_CAP_SPLIT_IRQCHIP enables the construction of LAPICs without the
rest of the irqchip.
Compile tested for x86.

In order to support a userspace IOAPIC interacting with an in kernel
APIC, the EOI exit bitmaps need to be configurable.
If the IOAPIC is in userspace (i.e. the irqchip has been split), the
EOI exit bitmaps will be set whenever the GSI Routes are configured.
In particular, for the low MSI routes a
Adds KVM_EXIT_IOAPIC_EOI which allows the kernel to EOI
level-triggered IOAPIC interrupts.
Uses a per VCPU exit bitmap to decide whether or not the IOAPIC needs
to be informed (which is identical to the EOI_EXIT_BITMAP field used
by modern x86 processors, but can also be used to elide kvm IOAPIC E
In order to enable userspace PIC support, the userspace PIC needs to
be able to inject local interrupts even when the APICs are in the
kernel.
KVM_INTERRUPT now supports sending local interrupts to an APIC when
APICs are in the kernel.
The ready_for_interrupt_request flag is now only set when the
