iodev.h contains definitions for the kvm_io_bus framework. This is needed both by the generic KVM code in virt/kvm as well as by architecture specific code under arch/. Putting the header file in virt/kvm and using local includes in the architecture part seems at least dodgy to me, so let's move the file into include/kvm, so that a more natural "#include <kvm/iodev.h>" can be used by all of the code. This also solves a problem later when using struct kvm_io_device in arm_vgic.h. Fixing up the FSF address in the GPL header and a wrong include path on the way.

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

This changes bus accesses to use high-level kvm_io_bus_read/kvm_io_bus_write functions. in_range now becomes unused so it is removed from device ops in favor of read/write callbacks performing range checks internally. This allows aliasing (mostly for in-kernel virtio), as well as better error handling by making it possible to pass errors up to userspace. Signed-off-by: NMichael S.

slots_lock is taken everywhere when device ops are called. Document this as we will use this to rework locking for io. Signed-off-by: NMichael S. Tsirkin <mst@redhat.com> Signed-off-by: NAvi Kivity <avi@redhat.com>

We modernize the io_device code so that we use container_of() instead of dev->private, and move the vtable to a separate ops structure (theoretically allows better caching for multiple instances of the same ops structure) Signed-off-by: NGregory Haskins <ghaskins@novell.com> Acked-by: NChris Wright <chrisw@sous-sol.org> Signed-off-by: NAvi Kivity <avi@redhat.com>

Modify member in_range() of structure kvm_io_device to pass length and the type of the I/O (write or read). This modification allows to use kvm_io_device with coalesced MMIO. Signed-off-by: NLaurent Vivier <Laurent.Vivier@bull.net> Signed-off-by: NAvi Kivity <avi@qumranet.com>

This paves the way for multiple architecture support. Note that while ioapic.c could potentially be shared with ia64, it is also moved. Signed-off-by: NAvi Kivity <avi@qumranet.com>
