If +the selected entry is writable, the guest can rewrite it through the data +register. + +The selector register takes keys in big endian byte order. + +The data register allows accesses with 8, 16, 32 and 64-bit width (only at +offset 0 of the register). Accesses larger than a byte are interpreted as +arrays, bundled together only for better performance. The bytes constituting +such a word, in increasing address order, correspond to the bytes that would +have been transferred by byte-wide accesses in chronological order. + +The interface allows guest firmware to download various parameters and blobs +that affect how the firmware works and what tables it installs for the guest +OS. For example, boot order of devices, ACPI tables, SMBIOS tables, kernel and +initrd images for direct kernel booting, virtual machine UUID, SMP information, +virtual NUMA topology, and so on. + +The authoritative registry of the valid selector values and their meanings is +the QEMU source code; the structure of the data blobs corresponding to the +individual key values is also defined in the QEMU source code. + +The presence of the registers can be verified by selecting the "signature" blob +with key 0x0000, and reading four bytes from the data register. The returned +signature is "QEMU". + +The outermost protocol (involving the write / read sequences of the control and +data registers) is expected to be versioned, and/or described by feature bits. +The interface revision / feature bitmap can be retrieved with key 0x0001. The +blob to be read from the data register has size 4, and it is to be interpreted +as a uint32_t value in little endian byte order.
