...sual. While this patchset only implements dumping kernel log buffer, it can be extended to have ftrace buffer and probably 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....
