I think the question here is do we have an implementation for OPM (OS Policy Manager) which would be in practice the driver we have for UCSI in Linux kernel. System policy manager is implemented in BIOS and/or EC FW with UCSI (check Figure 2-1 in bios-implementation-of-ucsi.pdf). > - If yes to USB-C system policy, are there any requirements that differ from > the published Intel White paper on UCSI support through ACPI Mailbox method? > (Link: > http://www.intel.com/content/dam/www/public/us/en/documents/white-papers/bios-implementation-of-ucsi.pdf > ) No other requirements.
