[Qemu-devel] [ARM SMBIOS V3 PATCH 0/5] 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. This new version (V3) integrates SMBIOS 3.0 support
for ARM mach-virt. I have tested this version using a customized AAVMF
created by Laszlo, who has submitted his patches to OVMF mailing list.

V2->V3:
 * Removed unncessary ram_size paramemter (patch 3 in V2, Laszlo)
 * Fixed UUID encode (Laszlo)
 * Added -smbios option (Leif)
 * Fixed misc variable defintion (Laszlo)
 * V2 regression tested on x86 (Gabriel and Leif)

V1->V2:
 * Add NULL checking for fw_cfg (Shannon Zhao)
 * Init 3.0 entry point table max size to smbios_tables_len (Laszlo)
 * Minor re-arrangement of smbios.h layout with function headers to the bottom
 * Validated SMBIOS 3.0 tables with a customized AAVMF created by Laszlo

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,
-Wei
