Hi,
here's the respin of the virtio-ccw guest support patches
(from http://marc.info/?l=kvmm=135151606921361w=2).
Changes to the last version:
- cc'ed stable for patch 1
- coding style fixes in patches 4 and 5
Cornelia Huck (5):
KVM: s390: Handle hosts not supporting s390-virtio.
s390
channel I/O instructions that can dequeue pending I/O
interrupts: tpi and tsch (not the part actually interacting with
the subchannel). This makes the interface less complex (only one
new exit for tsch handling) and avoids duplicating code from qemu.
Cornelia Huck (5):
KVM: s390: Support for I/O
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.

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.

These virtio-ccw devices use a special set of channel commands in order

Hi,
here's the virtio-ccw guest support for kvm/next again.
The not-kvm specific patches have made their way upstream via the
s390 tree in the meantime. Patch 2 fixes an inconsistency there.
Patch 3 lost the now unneeded schid.h include; otherwise, the patches
are unchanged from v4.

In rare cases a virtio command might try to issue a ccw before a former
ccw was answered with a tsch. This will cause CC=2 (busy). Lets just
retry in that case.

Dynamically allocate any data structures like ccw used when
doing channel I/O. Otherwise, we'd need to add extra serialization
for the different callbacks using the same data structures.

Hi,
I've been working on a new virtio transport for s390 replacing the
existing s390-virtio transport. Patches to Linux, qemu and the virtio
spec will follow.
Why?
s390-virtio is quite limited in the number of supported devices (all
related structures need to fit into a single specially mapped
) are outsourced to user space. This in-kernel
channel subsystem support can be enabled by user space via a new
capability.
Cornelia Huck (7):
s390/kvm: Support for I/O interrupts.
s390/kvm: Add support for machine checks.
s390/kvm: In-kernel handling of I/O instructions.
s390: Move css limits
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.

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/.
