[kvm-unit-tests PATCH 0/7] Extending VIRTIO with a data transfer test

[Pierre Morel <pmorel@linux.ibm.com>]

Hello All,

This series implement VIRTIO-CCW transport and a VIRTIO-CCW data
transfer test.

The first patch is for allowing different architectures to use the
existing VIRTIO framework used by ARM.

We then need a callback in the CSS enumeration to select a device,
and bind it with the VIRTIO transport, patches 2 and 3.

We need to be able to disable IRQ on the processor to protect
part of the code until we are ready to receive an IRQ, and we need
to have the registration and handling of IRQ at the VIRTIO level,
this is patch 4.

To be able to receive data we extend the comon VIRTIO code with an
input routine, patch 5.

Patch 6 and 7 are the two tests patches to implement simple VIRTIO
initialization, very few tests of integrity now which can be expend
later, and a data transfer test to check various alignement and sizes
of buffers and to check the data integrity with a simple checksum.

To test the last part you will need the associated QEMU device published
in another series on the QEMU mailing list.

Regards,
Pierre
