What has changed that allows them to do this, or are they just ignoring the HDMI Forum?

    What is the difference between this implementation and the reverse engineered patches that were published a few months ago by Michał Kopeć and Tomasz Pakuła?

    Edit: apparently it’s not the same patch, but Tomasz was CC’ed in the patch set so the timing might not be accidental.

    I wonder what this means for the Steam Machine.

    Title is clickbait. All that's been confirmed so far is FRL.

    Typical Phorinix. Wil not elaborate what FRL is.

    The first paragraph:

    It's not complete HDMI 2.1 support but to much surprise hitting the mailing list today were official patches from AMD for implementing HDMI Fixed Rate Link "FRL" support for their kernel graphics driver. HDMI FRL as part of HDMI 2.1+ allows for higher bandwidth to support higher refresh rates and resolutions.

    How much more of an explanation do you need?

    I’m no expert, but basically the way to unlock higher/full bandwidth for HDMI 2.1. This will allow the use of higher refresh rate, resolution, and bit depth + HDR. Right now you need to make sacrifices in at least one category with HDMI

    LOL... Surprised they aren't only doing so for their workstation cards like they do for everything else. The SR-IOV disablement is just greed at its finest. AMD also just released their new CPU with only difference 3D cache on the orher side & they're charging like an extra $300 for it.

    Not that I want to defend AMD but the reason they haven't been able to is because HDMI is a private spec and the HDMI forum specifically forbade them from releasing the driver they tried to publish a few years ago (even though the firmware with the actual implementation is in the GPU itself and still proprietary). That's why 2.1 works on windows and not Linux with the past 2 gens of AMD GPUs.

    Valve is probably adding that to the Steam Machine as we speak.

    Also, fuck the HDMI Forum!

    I use Display Port on my main PC monitor. Recently I added a secondary screen, a bigger TV screen, just to watch films on it. Neither I have a second Display Port on my GPU, nor have the TV any. So we are stuck with HDMI to a degree.

    UPDATE: Even more exciting... Per this comment from a prominent AMD Linux developer, it looks like a full HDMI 2.1 implementation for AMDGPU could be coming!

    Could be, key word "could." I'll believe it when I see it.

    They already mentioned DSC is lined up to go out but still needs compliance testing, so the code is probably ready. The "could" wording is by Phoronix not the AMD developer.

    This work was already finished 3 years ago but couldn't be sent out due to the HDMI Forum blocking it.

    I feel like this whole HDMI 2.1 thing is only an issue for a minority of people with ultra high end expensive monitors, and is overblown as a result.

    4K 120Hz is a really common TV input and even this is not possible in HDMI 2.0 without 4:2:0 chroma subsampling which is visually lossy especially in desktop usage.

    I'd wager that people who have linux and are plugging in TVs to run at 4k 120 are probably also not significantly in the majority.

    i mean, sure, do it, we deserve to have feature parity with windows, but its not a problem that is affecting the masses.

    Hooray for not-bullshit!

    Also, fuck you HDMI Consortium, if you are reading this.

    Ah, so now the Steam Machine can release, right?

    Right?

    Guess i can throw out my adapter that i bought literally like 2 months ago, and haven't even really used it yet cause i haven't been gaming much in that timeframe lmao. I guess it's good news though. And an obligatory fuck the hdmi forum.
