Subject: [edk2-platforms PATCH 0/2] Platform/RPi3: PlatformSmbios improvements
Date: Wed, 4 Sep 2019 13:14:16 +0100 [thread overview]
Message-ID: <20190904121418.3700-1-pete@akeo.ie> (raw)
This series of patches improves the data reported by the firmware for SMB queries.
This is achieved by first introducing new calls in RpiFirmwareDxe and then cleaning
up the existing PlatformSmbiosDxe code. These modifications should ensure that
the drivers can be reused on other Raspberry Pi platforms (such as the Pi 4).
It should be noted that, with these changes, if one passes a build option like
--pcd gEfiMdeModulePkgTokenSpaceGuid.PcdFirmwareVersionString=L"UEFI Firmware v1.7"
the BIOS major and minor will be populated from that version data.
Attached below is the report from dmidecode on Linux/Debian for a Raspberry Pi 3 B+
using a firmware with the above. Similar data can also be obtained through
smbiosview in the UEFI Shell.
Regards,
/Pete
