Maybe we should record these IDs at some place. Since QEMU is owner of this device and we register QEMU in ASWG, the official ID can be assigned by QEMU and the ID could(or should) be "QEMUXXXX". But what's the exact ID for this virtio-mmio? That's what we need to agree on and record. P.S. I don't see "QEMU" in the list of approved Vendor IDs for ACPI. http://www.uefi.org/sites/default/files/resources/PNPID_List.pdf http://www.uefi.org/sites/default/files/resources/ACPIID_List.pdf -- Shannon -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
