Finally A Discussion Is Back Concerning FreeSync / Adaptive-Sync / VRR DRM Support

[droste]

I think this is a bit confusing. So, which driver is sending a frame and which one is receiving it? Surely it's not the same (kernel) driver, right? I would guess user space driver (Mesa or DDX?) is sending it to kernel space but I may be wrong.

Pretty sure the second "driver" is actually a "display"

You are probably right. That didn't come to my mind.

As someone who has already had the hardware for years and experienced Freesync on Windows, I should say that the wait is a little bit annoying but at the same time I think it's great that they are collaborating and that it's important it's not rushed so that the end result is a good and future proof implementation.

You can already use freesync on the unified driver stack. This discussion is pertaining to common upstream DRM support.

I wonder if nouveau will support it...

it has to be supported by hardware first. nvidia hardware does not support it. don't buy nvidia

Nvidia hardware is very well capable of varibable refresh rates. They only limit it to external G-Sync displays because they earn extra money with them. However, they also support "G-Sync" in notebooks that don't have the actual G-Sync module but are driven by regular embedded DisplayPort, which means their GPUs would in fact be capable of supporting Adaptive Sync.
I'd be really happy if Nouveau devs would jump into this discussion and eventually implement Adaptive Sync for Nouveau. It would be a huge punch in Nvidia's face.

nvidia supporting freesync but only on linux will make for some nice memes

Wouldn't a better punch be not to buy their products?

That'd be more like slow chinese water torture than a punch in the face.

This developer, Manasi Navare, already has some experimental patches he is about ready to send out.

The gender is wrong, Michael. But it's not your fault. I can understand that it can be hard to guess the gender of foreign names.

Fixed, thanks.
