The Raspberry Pi 4 Broadcom Genet network adapter can be made to work in ACPI mode under high level OSes such as Linux.
To facilitate this however, it is desirable to ensure that the platform's MAC address has properly been written to the dedicated UMAC registers during UEFI initialization. This series of patches achieves that by: * Adding a generic Genet driver stub under Silicon that, for the time being, simply performs UMAC init when a MAC Address PCD has been set. * Adding a new PlatformPcdLib in the Raspberry Pi try, to ensure that, if no MAC address PCD was provided for the build, we set that PCD by querying the firmware interface. * Enabling the Genet driver for the Pi 4 platform Jeremy Linton (2): Silicon/Broadcom/Net: Add Genet stub driver to setup MAC Platform/Rpi4: Enable Broadcom Genet stub driver Pete Batard (1): Platform/RPi: Add PlatformPcdLib to set the Genet MAC address Platform/RaspberryPi/Library/PlatformPcdLib/PlatformPcdLib.c | 61 +++++++++++ Platform/RaspberryPi/Library/PlatformPcdLib/PlatformPcdLib.inf | 44 ++++++++ Platform/RaspberryPi/RPi4/RPi4.dsc | 5 + Platform/RaspberryPi/RPi4/RPi4.fdf | 1 + Silicon/Broadcom/Drivers/Net/BcmGenetDxe/BcmGenetDxe.inf | 40 +++++++ Silicon/Broadcom/Drivers/Net/BcmGenetDxe/Genet.c | 114 ++++++++++++++++++++ Silicon/Broadcom/Drivers/Net/BcmGenetDxe/Genet.h | 20 ++++ Silicon/Broadcom/Drivers/Net/BcmNet.dec | 22 ++++ 8 files changed, 307 insertions(+) create mode 100644 Platform/RaspberryPi/Library/PlatformPcdLib/PlatformPcdLib.c create mode 100644 Platform/RaspberryPi/Library/PlatformPcdLib/PlatformPcdLib.inf create mode 100644 Silicon/Broadcom/Drivers/Net/BcmGenetDxe/BcmGenetDxe.inf create mode 100644 Silicon/Broadcom/Drivers/Net/BcmGenetDxe/Genet.c create mode 100644 Silicon/Broadcom/Drivers/Net/BcmGenetDxe/Genet.h create mode 100644 Silicon/Broadcom/Drivers/Net/BcmNet.dec -- 2.21.0.windows.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
