Valve Developer Starts Poking At Open-Source "RADV" Driver Support For GFX11/RDNA3

Oof. Sorry to hear that. I hope they're not one of the bad ones.

Are you kidding? I love this gig. I can work on something interesting that I enjoy. It's vastly better than any of my previous jobs.

Venemo and Co are doing a terrific job. I'm glad that we have them (from community POV). For the moaners amongst us: Just have a look at their commits. Its continiously great work since years. Just let them do their job. They will provide the demanded features once they can. If they can't I highly doubt that anyone else is capable.

Some progress in that regard has been made recently. The shader IO cleanup, the ACO shader info refactor etc. are all important steps towards this goal.

Thank you and the other devs for your work! I have a 6800 XT, too, but have not really tried any RT stuff other than Vulkan demos. I look forward to aco+radeonsi if it can improve performance in the many existing OpenGL games.

Can radv be used on Windows in theory? I.e. may be AMD can drop amdvlk and just help develop radv as well?

From what I've heard, the reason they didn't want to back radv was due to the interest to have a unified code between different OSes. But if it can be used on Windows, it will be good for that.

That sounds great in theory, but TBH it seems like less work to minimally but officially support RADV and carry on with the current Windows driver.


With compute going to the rocm stack, who is even using AMD's closed or open source driver now? The userbase seems to be people who accidentally installed it instead of the community driver, or who are working around some issue.

Most of us are subcontractors (not employees).

Oof. Sorry to hear that. I hope they're not one of the bad ones.

For those of y'all who don't know -- subcontractor basically means you get all the pay of a job and, almost usually, none of the perks or benefits that an employee of that company will receive, no way to unionize or engage in collective bargaining, and if you don't read your contract well enough you might sign away enough rights that you end up as "well off" as a worker in a "right to work" state.

I really hope to get the RT features in RADV to use all things my card is capable of.

RT is already usable with some games, but not all. We don't have CP2077 RT yet, but it's a work in progress.

This article is about GFX11 (and task shaders) enablement, while you are asking about RT which is unrelated to these things. That being said, You can check out the open merge requests for RADV in the Mesa Gitlab and you can see there is ongoing work to improve RT.
....

Maybe my fault to see RADV more as "one piece of thing".
I did not want to blame someone.
It is just so, that I really hope to get the RT features in RADV to use all things my card is capable of. It is hard to judge how much effort goes in this and how long it may take.

Yeah you're not commanding, you're suggesting it in a totaly unrelated topic. If I where a dev, i woud really be pissed.

If you are pissed, if someone politely points out what he wishes to have, that is surely your problem.

Would be one thing if this was a rare exeption, but you can basically read such shit under every OS news "why does dev X do Y, I need Z now! Such a waste of time!!!! Do it the right way, my way!!!!111".

Sorry I kind of got hung up by that, I should just chill and mind my own bussines.

I did not write something like that.

And here's the double-edged sword of this particular topic -- they're paid employees of Valve.

OT: Does the steam console support raytracing (it's RDNA2 so it might be in there)

The Steam Deck has an RDNA2 GPU, the hardware indeed has the necessary features for RT, mesh shading etc.
