    Any activity on this or anyone know? I have a patch that hacks in the so-called "WattMan" option based on choosing "manual" for the profile. At least, it allows all but Custom.

    Hey mitch074

    I would be interested to know please what you did to reduce the voltage on your Polaris?
    I did it using WatMan under Windows - I'd love being able to do so under Linux too.

    Wattman [and feature parity with Windows] and OpenCL straight out of the box, as they say, checks off all my needs.

    These series were never per generations:

    HD7xxx and HD8xxx series were mixage of VLIW5, GCN 1.0 and GCN 1.1
    R* 200 serie is mixage of VLIW5, GCN 1.0, GCN 1.1 and GCN 1.2
    R* 300 serie were mixage of GCN 1.0, GCN 1.1, GCN 1.2

    Simply said, only Bonaire and Hawaii and their variants/revisions are GCN 1.1 else is GCN 1.0, with exception of Tonga and its revisions which is GCN 1.2. and Fury that is also VI but with PI point .

    AFAIK WattMan doesn't work on this series.. GCN 2nd Generation (Sea Islands)

    https://en.wikipedia.org/wiki/Graphi...lcanic_Islands)
    It should work, just read patches there... it won't on Sea Islands APUs but on Sea Islands cards it should i think.

    It works on CI and VI, just don't work same way internally as on AI (Polaris).

    These are not SI familes, that is CI and VI.

    SI (GCN 1.0) is Southern Islands
    CI (GCN 1.1) is Sea Islands
    VI (GCN 1.2) is Volcanic Islands

    There are other names for these like - first, second and third GCN generations or even GFXIP 6/7/8 if you like (to not mention some points of these as we would be better to talk near per asic) Polaris is 4th gen, Vega is 5th gen and so on.

    Michael seems like to put these click bait articles, when someone says Radeon™ WattMan users think of GUI of it - but this isn't that

    Or did AMD still decide to make support for the old cards?
    Simply said - what is possible to be enabled they enable.

    Maybe people here only read articles, but not patches i dunno

    But this is Tonga as that is VI... should work on CI also it seems (these are Hawaii and Bonaire cards)

    Basically on any card which is up to 5 year old, but is not GCN 1.0

    Overclockers. And people who just want to calmly customize the product. Bypassing Linux features

    Manual controls should be working at this stage it appears for Sea Islands and Volcanic Islands GPUs on AMDGPU DRM.
