Feedback from Arm for reference board

  • NXP I.MX8M platform - “The SCMI questions aside, I honestly do not think the iMX8 is a very good example to work with. The non-BSA compliant UART and PCIe are especially concerning, but that can be said for most SoCs in this space. Also, there is no good reference UEFI/ACPI EDK2 open-source code for the iMX8. There is code that can be downloaded from NXP that combines the Uboot FW (as a low-level initialization FW) with UEFI implementation from MS Project Mu (using EDK2 components, but not exactly EDK2). The Project Mu components add UEFI, ACPI, and SMBIOS on top of Uboot. However, as far as a I know, that combination lacks several UEFI pieces, which results in limited OS boot at least for now (only boots Windows, not Linux).”

  • RK356x based boards like the PINE64 Quartz64

  • Phytium SoC - “The Phytium SoC-based PC is the best as far as I know. It supports all OSes very nicely with ACPI support. They also have an EC solution in their laptops.”

Fugang & Jammy - Made good progress on NXP platform and can boot into UEFI shell. Lack of open-source EDK2 implementation is not a big concern. CIX is confident on progressing with NXP platform.

Phytium Soc: Jammy - It only has discrete GPU and no integrated GPU and leverage PCI support. Not interesting for low power investigation. Documentation and support would be challenging.

NXP SCU firmware is not open-source. Jammy - Can we get NXP support through official channel ? Mike - In discussions with NXP, but does not look likely now. We could ask for help through community/development support channels.

Lorenzo - No netural and ideal platform exists for power management, we need to start somewhere.

 

FVP for SCMI work

Jammy - Can we use Morello FVP instead of Neoverse as Morello is closer to a client device ? Shashi - Yes, that’s possible.
