This isn't something AMD supports. The APU coefficients are set by system designers in their firmware as a result of the hardware design decisions. That's why I'm fixating on getting the method of coefficient configuration working. Some OEMs do it entirely in their EC, some do it entirely in PMF, some do a combination and some it with the involvement of code running in TEE. We will need to wait until the other bits are supported by amd-pmf to revisit this issue. -- You may reply to this email to add a comment.
