similar to: [RFC/PATCH 15/15] guest: virtio device support, and kvm hypercalls

There is no recent user space application available anymore which still supports this old virtio transport. Additionally, commit 3b2fbb3f06ef ("virtio/s390: deprecate old transport") introduced a deprecation message in the driver, and apparently nobody complained so far that it is still required. So let's simply remove it. Signed-off-by: Thomas Huth <thuth at redhat.com> ---

Salve, the German IT-Magazin (#1) www.heise.de/ct has made an audio-codec test online. The reader were asked to download 2 x 7 audiofiles, listen to them and rank them (As I wrote before) http://www.xiph.org/archives/vorbis/200208/0185.html The 7 files have been Wave, MP3, MP3Pro, AAC, Ogg Vorbis, WMA, RealAudio in 64kBit/s and 128kBit/s for a stereo sample of 3 genres: pop, jazz, classic.

This patch series introduces a backend for kvm to run on IBM System z machines that uses the mainframe's sie virtualization capability. This work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with a 64bit linux host. Userspace will follow once we're done brushing it over. The patch queue consists of the following patches, which can be applied in sequence on top of kvm.git

This replaces find_vq/del_vq with find_vqs/del_vqs virtio operations, and updates all drivers. This is needed for MSI support, because MSI needs to know the total number of vectors upfront.

Currenty the ext_param field only distinguishes between "config change" and "vring interrupt". We can do a lot more with it though, so let's enable a full byte of possible values and constants to #defines while at it.

From: Rusty Russell <rusty at rustcorp.com.au> Add a linked list of all virtqueues for a virtio device: this helps for debugging and is also needed for upcoming interface change. Also, add a "name" field for clearer debug messages. Signed-off-by: Rusty Russell <rusty at rustcorp.com.au> --- including this Rusty's patch here for completeness.

Extend features to 64 bit so we can use more transport bits. Future patches add two new feature bits which would exhaust the supply of transport feature bits, so let's add bit 31 to tell the guest that there are now 64 worth of features. For PCI this also changes the config layout. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> --- drivers/lguest/lguest_device.c | 8
