[Qemu-devel] [ARM SMBIOS V1 PATCH 0/6] SMBIOS Support for ARM

[Wei Huang]

SMBIOS tables present userful system hardware info to management
applications, such as DMI tools. Even though SMBIOS was originally
developed for Intel x86, it has been extended to both Itanium and 
ARM (32bit & 64bit). More and more ARM server releases, such as 
RHEL Server for ARM, start to integrate support for SMBIOS.

This patchset is intendted to provid SMBIOS tables for ARM mach-virt
machine. The SMBIOS tables are created and stored in fw_cfg, relying on
OVMF (AAVMF) to parse/present SMBIOS entry.

RFC version have been tested by Laszlo using his customized version of
AAVMF. We were able to detect SMBIOS 2.8 tables using dmidecode inside
an AArch64 guest VM. Moving forward, it is better to support SMBIOS 3.0
for ARM guest VM. This new version (V1) integrates SMBIOS 3.0 support
for ARM mach-virt. I have tested this version by forcing SMBIOS 2.1
format (i.e. passing SMBIOS_21_ENTRY_POINT to smbios_set_defaults()).
SMBIOS 3.0 hasn't been tested yet as it requires AAVMF to install 3.0 entry.

RFC->V1:
 * Add SMBIOS 3.0 support for buidling SMBIOS
 * Switch from SMBIOS 2.1 to 3.0 for ARM mach-virt
 * RFC version Tested-by Laszlo Ersek and Acked-by Gabriel Somlo

Thanks,
