    Default Linux 3.13 To Enable Radeon DPM, HDMI Audio

    Phoronix: Linux 3.13 To Enable Radeon DPM, HDMI Audio

    AMD has made known the changes they have lined up for the Linux 3.13 kernel merge window. Among the work includes finally enabling Radeon Dynamic Power Management (DPM) for some graphics processors and also restoring HDMI audio support to be enabled by default...

    Already using Kubuntu 14.04 here, it won't be interesting for a while yet.

    That seems to be incorrect, or at least incomplete.

    DPM is enabled by default for most chips now, in particluar:

    case CHIP_RV770:
    case CHIP_RV730:
    case CHIP_RV710:
    case CHIP_RV740:
    case CHIP_CEDAR:
    case CHIP_REDWOOD:
    case CHIP_JUNIPER:
    case CHIP_CYPRESS:
    case CHIP_HEMLOCK:
    case CHIP_PALM:
    case CHIP_SUMO:
    case CHIP_SUMO2:
    case CHIP_BARTS:
    case CHIP_TURKS:
    case CHIP_CAICOS:
    case CHIP_TAHITI:
    case CHIP_PITCAIRN:
    case CHIP_VERDE:
    case CHIP_OLAND:
    case CHIP_HAINAN:
    It is still disabled by default on:

    case CHIP_RV610:
    case CHIP_RV630:
    case CHIP_RV620:
    case CHIP_RV635:
    case CHIP_RV670:
    case CHIP_RS780:
    case CHIP_RS880:
    case CHIP_CAYMAN:
    case CHIP_ARUBA:
    case CHIP_BONAIRE:
    case CHIP_KABINI:
    case CHIP_KAVERI:
    So I think that's the old 2xxx cards, 3xxx, the old MB integrated parts from back then, the 69xx, and some of the newer SI parts.

    To be more exact, some recent cards not using DPM are: HD 6950/6970, HD 7790 and the upcoming Kaveri IGPs.

    Well good, I've been using DPM on my 7850 since kernel 3.11 came out and I had zero issues, seems to me it's ready to be default.

    About HDMI audio: does it work on radeonsi as well? Because even if I boot with radeon.audio=1 I get no sound, the device doesn't even appear in pulseaudio...

    I can't figure out if this means it's enabled for a 7660D (A10-5800K Trinity) APU or not.
