|---|---|
SCMI and ACPI SCMI has good capabilitiy with ACPI. SystemReady does not mandate any power methods. No perfect device exist today for client PC power management related work. Juno is outdated. SCMI interface could be emulated in TF-A. QEMU could be potentially used to build an emulated platform with acpi power methods and capabilities to validate the software stack. Lorenzo can put the details (e.g: what needs to be emulated etc.) on confluence and Shashi can identify if anymore work is required on QEMU to support that. | |
RD-N2 FVP Feedback Lorenzo - FVP can be also used for power management emulation. | |
Power management tests in FWTS | |
Rasbperry Pi Power Management Platform statistics for ACPI support Last Meeting Actions：2022-07-20 Meeting notes RPi has only limited power management capabilities and does not look like a suitable platform for power management capabilities | |
NXP i.MX8MP could be a potential reference platform for PM works. Good support for power management capabilities in device tree. EDK2 firmware bring up might be required. Add IMX platform support to the table. | |
Linux ACPI power management summary Client PC - Linux ACPI low power alignment ticket： CLIENTPC-8 - Getting issue details... STATUS Jammy - Platforms needs to be decided before we can investigate the tasks. | |
Reference Platform for Power, Performance and Thermal Management Jammy - Can we add an extra column in acpi platform table to capture platforms that could be extended for a missing feature. |
