KVM: Bump KVM_MAX_IRQ_ROUTES for s390

2014-03-21T12:43:13+00:00

The maximum number for irq routes is currently 1024, which is a bit on
the small size for s390: We support up to 4 x 64k virtual devices with
up to 64 queues, and we need one route for each of the queues if we want
to operate it via irqfd.

Let's bump this to 4k on s390 for now, as this at least covers the saner
setups.

We need to find a more general solution, though, as we can't just grow
the routing table indefinitly.

KVM: s390: irq routing for adapter interrupts.

2014-03-21T12:43:00+00:00

Introduce a new interrupt class for s390 adapter interrupts and enable
irqfds for s390.

This is depending on a new s390 specific vm capability, KVM_CAP_S390_IRQCHIP,
that needs to be enabled by userspace.

KVM: Simplify kvm->tlbs_dirty handling

2014-02-18T09:07:26+00:00

When this was introduced, kvm_flush_remote_tlbs() could be called
without holding mmu_lock.  It is now acknowledged that the function
must be called before releasing mmu_lock, and all callers have already
been changed to do so.

There is no need to use smp_mb() and cmpxchg() any more.

KVM: async_pf: Provide additional direct page notification

2014-01-30T11:51:38+00:00

By setting a Kconfig option, the architecture can control when
guest notifications will be presented by the apf backend.
There is the default batch mechanism, working as before, where the vcpu
thread should pull in this information.
Opposite to this, there is now the direct mechanism, that will push the
information to the guest.
This way s390 can use an already existing architecture interface.

Still the vcpu thread should call check_completion to cleanup leftovers.

KVM: s390: add floating irq controller

2014-01-30T09:25:20+00:00

This patch adds a floating irq controller as a kvm_device.
It will be necessary for migration of floating interrupts as well
as for hardening the reset code by allowing user space to explicitly
remove all pending floating interrupts.

kvm: make local functions static

2014-01-08T21:02:58+00:00

Running 'make namespacecheck' found lots of functions that
should be declared static, since only used in one file.

KVM: arm-vgic: Support KVM_CREATE_DEVICE for VGIC

2013-12-21T18:01:16+00:00

Support creating the ARM VGIC device through the KVM_CREATE_DEVICE
ioctl, which can then later be leveraged to use the
KVM_{GET/SET}_DEVICE_ATTR, which is useful both for setting addresses in
a more generic API than the ARM-specific one and is useful for
save/restore of VGIC state.

Adds KVM_CAP_DEVICE_CTRL to ARM capabilities.

Note that we change the check for creating a VGIC from bailing out if
any VCPUs were created, to bailing out if any VCPUs were ever run.  This
is an important distinction that shouldn't break anything, but allows
creating the VGIC after the VCPUs have been created.

KVM: Use cond_resched() directly and remove useless kvm_resched()

2013-12-13T13:23:45+00:00

Since the commit 15ad7146 ("KVM: Use the scheduler preemption notifiers
to make kvm preemptible"), the remaining stuff in this function is a
simple cond_resched() call with an extra need_resched() check which was
there to avoid dropping VCPUs unnecessarily.  Now it is meaningless.
