Originally posted by M@yeulC View PostThe solution would be to make the two codebases gradually closer, and ending up with exactly one codebase.
But the way AMDVLK is developed with regular code drops isn't really open source friendly, as far as development goes.
Originally posted by IreMinMon View PostAfaik, both AMDVLK and RADV are opensource, so they could at any point copy the code over to their driver. This is competition + collaboration. And is imho very good for end user.

That seems rather unnecessarily insulting, given that there are IMO some pretty reasonable concerns about the contribution process and distribution of amdvlk. And it's obviously tough to just abandon something you've worked hard on until you can really show it to be inferior - imagine throwing away radeonsi at this point in favor of a newly open sourced fglrx, for example.
Not to mention the fact that to date, radv has provided faster hardware support for every new card AMD has released than amdvlk. I realize bridgman keeps saying that next time it will be better, but we've been hearing that for a long time now and it hasn't happened yet...
Contributing to RADV should be a no brainer considering the success of RadeonSI.
And don't bring up cost: RADV is already a very mature driver and it currently costs AMD literally *nothing*.
I'm really curious about Intel entering the discrete GPU market with open-source drivers and adaptive-sync support.
Should bring interesting competition to AMD.

What I have been talking about is degree of open source driver support in general at launch, and most of the time I was saying it was years ago.Test signature

Anyway, my point was very much that I feel like a lot of things have been said about how good amdvlk will be, but it's an open question how much that can be trusted. I'm not saying this as an attack by any means, so please don't take it that way. But when you have things like the recent 590 card launch that fails to run on linux, and before that the major problems with Raven support, and the still to be worked on nature of GCN 1.0 vulkan/amdgpu support I think it's a very tough sell for AMD to say "trust us everything will be fine going forward and there's no need for anyone else to be able to do this themselves instead".
To be fair, all these issues are obviously much better than what was going on 5 years ago. I expect they'll continue to get better. It just doesn't feel like the driver situation on linux for AMD has really fully arrived at a place where it can always be given the benefit of the doubt yet. For me at least, it's in a "i'll believe it when i see it" state. As I mentioned in a previous post, I'm starting to see it in regards to performance so that's promising.Last edited by smitty3268; 26 November 2018, 04:33 PM.

Sorry if I conflated that with your more general posts about launch time support.
We haven't launched a new HW generation since both radv and AMDVLK have been out so it's hard to say what will happen. If things go well we will make the question academic by upstreaming radeonsi support sufficiently early and sampling HW sufficiently well to NDA customers with developers working on radv that both will be ready in time for launch anyways.Last edited by bridgman; 26 November 2018, 07:12 PM.Test signature

When in China RX 570 could be 580 so why not, everybody would have clear picture on steam survey anyway
