[RFC/PATCHSET 0/3] virtio: Implement virtio pstore device (v4)
...bly some more..
The patch 0001 implements virtio pstore driver. It has two virt queue
for (sync) read and (async) write, pstore buffer and io request and
response structure. The virtio_pstore_req struct is to give
information about the current pstore operation. The result will be
written to the virtio_pstore_res struct. For read operation it also
uses virtio_pstore_fileinfo struct.
The patch 0002 and 0003 implement virtio-pstore legacy PCI device on
qemu-kvm and kvmtool respectively. I referenced virtio-baloon and
virtio-rng implementations and I don't know whether kvmtool supports
modern virtio 1.0...
