    You won't get anything as sophisticated as that, not as long as AMD have guys controlling the open source driver. The code is horrible, and based on what I've seen, that's intentional. The...

    I guess that explains it.

    Mr Duecher has now gone off on a bit of a tangent with this bug, throwing out the safe profiles and messing about with the clocks and voltages independently. Not really...

    The Cayman is weird. I don't think the 3rd and 4th power states are for dual head idle like they are on the Barts, because that would mean it would idle higher than a less powerful card. I suspect it...

    The idle states are different, for barts at least. On my card, engine clocks for single head is 100Mhz, dual head 300Mhz, and eyefinity 600Mhz. The mid and high states are always the same though, at...

    Hi, thanks that's useful. I can see that it has two performance states, one for single head and one for dual head. That's exactly what the current code is targeting, but which is absent in the HD6000...

    Any chance anyone with an hd6k can add drm.debug=2 to the kernel options and print the output of
    dmesg | grep "radeon_pm_print_states"

    For me it results in:

    Nope, the bad PM code is still in the latest kernel source. Doesn't seem as if anyone wants to touch it. I could submit a patch, but the r600 profile affects so many cards, I wouldn't know if I was...

    It's a bug I've been looking at lately: https://bugs.freedesktop.org/show_bug.cgi?id=49981

    It's because the card use different power states depending on whether it's running one or two heads. The...
