    Phoronix: AMD Works On Linux Power Savings For Future CPUs

    New kernel patches by AMD for the Linux kernel provide "frequency sensitivity feedback" for the powersave bias in cpufreq. This hardware feedback feature is to be introduced on future AMD processors...

Your situation is somewhat schizophrenic, you give us a buggy binary driver or an incomplete open source one.
    I have to ask about your "never" statement. You see the progress the open source driver is making -- other than power management and a bit more performance work, what do you think it is missing. If/when those bits are in place, will you still "never" buy from us ?

    P.D: Note this has nothing to do with you personally bridgman, because I know you are doing the best you can.
    Yep, but on my side this became "I will never buy nvidia again" and am going to be really careful about intel hardware (GMA 4500HD here, still waiting on video decode support).
    Why? As a linux-rc user/tester, binary drivers are a no-go. nvidia chips are incomplete ( SATA port multiplier support in my instance https://ata.wiki.kernel.org/index.ph...dware_features ). AMD on the other hand promised OSS drivers, and delivered. (Thanks)

    Now this new generation of APUs looks very promising. But my HTPC doesn't need an update yet

    Except for some GPUs. I have incorrect rendering and crashes where not even MagSysRQ works with the OSS driver while catalyst is (except some minor rendering issues) stable. I reported all bugs I've found to both camps and so far the catalyst guys are faster at fixing major bugs (talking about fixed-in-the-next-release vs. not-fixed-since-ages).

    You mean this? :P

    Well, it's interesting, but nothing is using it just yet, so we don't really know how effective it really is.

    Don't let the haters bother you.

    Once you release OpenCL and powersaving support, open drivers will be almost perfect, they will only need optimisations.

    In fact, when fully working dynamic powersaving is released, I bet most moaners will stop hating and love the drivers.

    Have choices now.

    It's a pity if that happens. But we have choices now. [overpriced] Intel, or [weaker processing] ARM
