Change ACPI tables to add HID-over-I2C device?
I need to add an entry for a HID-over-I2C device to the ACPI DSDT table.
I noticed that the Up Xtreme is supported by Intel's edk2 firmware project:
Before I buy an Up Xtreme and try to build edk2, I figured I would ask about existing HID-over-I2C support. Are there any existing HID-over-I2C entries in the stock ACPI table? If so, what is their configuration? (I2C bus, speed, etc).
If there are no existing entries, is it really necessary to build edk2 in order to change the contents of the ACPI DSDT table? (I need to use Windows 10 and not Linux). Is there an easier way to do it?
