The !KVM case is not yet supported.

There's no need to keep __MAX_SUBCHANNEL and __MAX_SSID private to the
common I/O layer when __MAX_CSSID is usable by everybody.

Hi,
here's the second version of virtual channel I/O and the new virtio-ccw
transport.
Changes to the first version include coding style fixes, changes in the
organization of objects (not quite finished yet), adaptions to changes
in the kernel interface and implementation of the improved
Hi,
this is the second revision of the virtio-ccw spec.
The interface has been improved to support more than 32 feature bits
as well as allocating less that the requested queue size and specifying
alignment.
(Note: I folded the changes with git into my initial spec; I hope LyX can
handle this
Add support for handling I/O interrupts (standard, subchannel-related
ones and rudimentary adapter interrupts).
The subchannel-identifying parameters are encoded into the interrupt
type.
I/O interrupts are floating, so they can't be injected on a specific
vcpu.

Explicitely catch all channel I/O related instructions intercepts
in the kernel and set condition code 3 for them.
This paves the way for properly handling these instructions later
on.
Note: This is not architecture compliant (the previous code wasn't
either) since setting cc 3 is not the
This patch enables using both virtio-xxx-s390 and virtio-xxx-ccw
by making the alias lookup code verify that a driver is actually
registered.
(Only included in order to allow testing of virtio-ccw; should be
replaced by cleaning up the virtio bus model.)

Running under a kvm host does not necessarily imply the presence of
a page mapped above the main memory with the virtio information;
however, the code includes a hard coded access to that page.
Instead, check for the presence of the page and exit gracefully

Hi,
here's the second revision of the virtual channel subsystem support for
s390.
I changed the representation of the channel subsystem, introducing channel
subsystem images, which brings it closer to the actual implementation. A

Hi,
here's the second revision of the guest support for virtio-ccw.
The first patch has gotten several changes and now handles checking
for s390-virtio support much more nicely.
The third patch has been adapted to the changed virtio-ccw interface.

kvm will need to use some css-related structures (pmcw, schib, orb),
so let's move the definitions from drivers/s390/cio/ to include/asm/.

Add support for injecting machine checks (only repressible
conditions for now).
This is a bit more involved than I/O interrupts, for these reasons:
- Machine checks come in both floating and cpu varieties.
- We don't have a bit for machine checks enabling, but have to use
a roundabout approach
