    Since this patch, any better raw specifications of the performance registers have been published for family 17h ?
    I will prefer going through MSR or PCI rather than ACPI.

    Windows engineers are not writing AMD's linux drivers, and regardless raw software engineer bodycount has nothing to do with changing company culture.

    No, you don't solve management and legal blocking or delaying upstreaming by throwing more software engineers at the problem. That requires a shift in thinking and overall workflow.

    @Michael: are you sure, it's only about Zen 2? The mailing list only mentions >=fam17h (Zen).

    Newer AGESA/BIOS versions should support CPPC2 on Zen 1 CPUs too, right? It would be interesting to see what kind of difference it makes.

    Credit to Intel for what they do, but they have far more resources than AMD does.

This isn't something that is simply solved by throwing money at it, it's a cultural change that has to take place, just look at the Navi code being held back by AMD's legal team. They simply aren't at the same level of maturity when it comes to contributing to linux and open source projects in general.

    Awesome! I hope they work on better Linux support for all of their hardware. Intel's [ability to spend more money] is just so much better at this point.
