which is included in series for completeness.
Changelog:
changes since v5: fix build on s390 (only patch 2/4 modified)
Michael S. Tsirkin (3):
virtio: find_vqs/del_vqs virtio operations
virtio_pci: split up vp_interrupt
virtio_pci: optional MSI-X support

[PATCHv6 3/4] virtio_pci: split up vp_interrupt
This reorganizes virtio-pci code in vp_interrupt slightly, so that
it's easier to add per-vq MSI support on top.

[PATCHv6 00/12] qemu: MSI-X support
Here is the port of MSI-X support patches to upstream qemu.
Please comment or commit.
This patchset adds generic support for MSI-X, adds implementation in
APIC, and uses MSI-X in virtio-net.
Changelog:
- since v5
make sure that load does not modify registers that guest can not change
replace global msix disable flag with a per-device flag to control the number of vectors
- since v4
rebased

[PATCHv6 0/3] vhost: a kernel-level virtio server
Rusty, ok, I think I've addressed your comments so far here. In
particular I have added write logging for live migration, indirect
buffers and virtio net header (enables gso). I'd like this to go
into linux-next, through your tree, and hopefully 2.6.33.
What do you think?

[PATCHv6 04/12] qemu/pci: check constant registers on load
Add "cmask" table of constant register masks: if a bit is not writeable
and is set in cmask table, this bit is checked on load. An attempt to
load an image that would change such a register causes load to fail.
Use this table to make sure that load does not modify registers that
guest can not change (directly or indirectly).
Note: we can't just assume that read-only registers never

[PATCHv6 12/12] qemu/net: flag to control the number of vectors a nic has
Add an option to specify the number of MSI-X vectors for PCI NIC cards. This
can also be used to disable MSI-X, for compatibility with old qemu. This
option currently only affects virtio cards.

[PATCHv6 1/3] tun: export underlying socket
Tun device looks similar to a packet socket
in that both pass complete frames from/to userspace.
This patch fills in enough fields in the socket underlying tun driver
to support sendmsg/recvmsg operations, and message flags
MSG_TRUNC and MSG_DONTWAIT, and exports access to this socket
to modules. Regular read/write behaviour is unchanged.
This way, code using raw sockets to inject packets

[PATCHv6 07/12] qemu/virtio: virtio support for many interrupt vectors
Extend virtio to support many interrupt vectors, and rearrange code in
preparation for multi-vector support (mostly move reset out to bindings,
because we will have to reset the vectors in transport-specific code).
Actual bindings in pci, and use in net, to follow.
Load and save are not connected to bindings yet, so they are left
stubbed out for now.

[PATCHv6 05/12] qemu/pci: MSI-X support functions
Add functions implementing MSI-X support. First user will be virtio-pci.
Note that platform must set a flag to declare MSI supported: this
is a safety measure to avoid breaking platforms which should support
MSI-X but currently lack this in the interrupt controller emulation.
For PC this will be set by APIC.
