Some more notes from Jon N. for the EDK2 UEFI/ACPI example context: QUOTE Things got a bit more complicated, after I looked at things some more. Basically BSD needs to grow I2C support for the LX2160a, which shouldn't be a big deal since it is mostly compatible with the normal IMX driver. END QUOTE and: QUOTE However to support devices that don't support the I2C controller I am writing a UEFI driver that can properly setup the PWM controller for Auto mode. This should allow the fan to ramp up and down without any needed OS support at all. END QUOTE He wondered if I knew enough to "check on the i2c controller support for imx in BSD, it could be a simple fix just by patching in ACPI support". Unfortunately, that looks to involve way more than I'd be likely to = figure out any significant part of anytime soon. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
