If so, it should have an ACPI > driver. If not, it shouldn't. It does not currently. However, the firmware is being developed along with the hardware and the OS. We have the opportunity to do whatever makes the most sense. My next-steps here were to get a basic ACPI ID setup for each of the three drivers just so they could be enumerated over ACPI rather than just loaded manually. Beyond that I'll be looking to Len and Rafael for guidance. -- Darren Hart Intel Open Source Technology Center Yocto Project - Technical Lead - Linux Kernel
