NXP i.MX8MP

Platform statistics for ACPI support

Fugang - Tested Linux DT and many features already supported. Firmware code is open-source. Nice for us to use this for ACPI enablement.

Niyas - WIndows driver are also available with source-code.

Lorenzo - Is runtime power management verified in DT for devices ? Fugang - Yes.

Lorenzo - Which devices have devfreq support ? Fugang - All IP seems to support device power management.

Jammy - If other options can also be used like QEMU/FVP/RPi depends on platform availability to Linaro people then this platform can be also used.

Niyas - Isn’t it better to consolidate the effort on one platform rather than fragmenting effort across multiple platform.

Platform evaluation board availability - CIX have access already, no access for linaro yet.

Jammy - CIX can help with initial enablement for the platform. Fugang can join for the firmware development.

Jammy - CIX can list features that they can enable initially for platform

ACPI/SCMI Power management with emulated platforms

Niyas - Parallel track to look at ACPI/SCMI with FVP

Jammy - Is it possible to enable any missing features with help of emulated platforms ? Niyas/Shashi - QEMU and FVP have good support for Linux ACPI. Probably nothing much we can enable with emulated platforms.
