My team mate Wei Huang started porting QEMU's "full" SMBIOS generator, originally authored by Gabriel, to qemu-system-(arm|aarch64), machine type "virt":
http://thread.gmane.org/gmane.comp.emulators.qemu/351072 This series does the same on the firmware side. The easy way to test it is the SMBIOSVIEW command in the UEFI shell. The hard way to test it is finding a combination of aarch64 guest software that doesn't choke on SMBIOS 2.8 (not 3.0 at the moment -- going to 3.0 will be QEMU-side work; the entry point version is controlled by QEMU). At the moment this means a v4.2-rc1+ guest kernel, and a dmidecode build (based on 2.12-dmifs) that knows to handle "/sys/firmware/dmi/tables/smbios_entry_point". Example dmidecode output (from a 4 VCPU aarch64 guest with 4 GB RAM): > # dmidecode 2.12-dmifs > SMBIOS 2.8 present. > 11 structures occupying 490 bytes. > Table at 0xFFFC0000. > > Handle 0x0100, DMI
