pseries has lots of stuff below /proc/device-tree. Dunno whenever that

Add support for persisting the key in --key-path. By default it will
accept the program-key command and store the key in the key file. If
you pass --key-set then the key is deemed to be programmed and can't
be re-programmed. Obviously you will need some other mechanism to let
the guest know what th

With this command we are finally updating data to the backing store
and cycling the write_count and each successful write. We also include
the write count in all response frames as the spec is a little unclear
but the example test code expected it.

This implements the first handshake of the device initialisation which
is the programming of the device key. This can only be done once
per-device.
Currently there is no persistence for the device key and other
metadata such as the write count. This will be added later.

This is mostly useful for testing. Practically all guest operations

The read command is a lot simpler to implement. However the spec does

This allows is to instantiate a vhost-user-rpmb device as part of a

This creates the QEMU side of the vhost-user-rpmb device which
connects to the remote daemon. It is based of the reasonably modern
vhost-user-fs code with bits from vhost-user-blk as we want the
virtio-config itself to be sourced from the daemon.

If you like running QEMU as a normal user (very common for TCG runs)
but you have to run virtiofsd as a root user you run into connection
problems. Adding support for an optional --socket-group allows the
users to keep using the command line.

This allows other device classes that will be exposed via PCI to be
able to do so in the appropriate hw/ directory. I resisted the
