Unable to completely replace vkd3d with vkd3d-proton?
by zhengxianwei 28 Nov '24

28 Nov '24

I tried replacing Wine’s built-in DLLs with the d3d12.dll compiled from vkd3d-proton and the dxgi.dll compiled from dxvk. However, I noticed that Wine’s built-in D3DCompile2 still calls vkd3d_shader_compiler( https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/d3dcompiler_43/compi…), which belongs to vkd3d, not vkd3d-proton. Does this mean that even in Proton, vkd3d and vkd3d-proton coexist, and it’s not possible to completely replace vkd3d? So if there’s a bug in it, I would still need to fix the issue in vkd3d rather than being able to replace it with functions from vkd3d-proton. Is that correct?

How could I use my own build vkd3d in wine ?
by zhengxianwei 26 Nov '24

26 Nov '24

I want to try modifying and building vkd3d myself, but I’m not sure how to make Wine use my custom-built vkd3d. My development environment is Ubuntu 24.04 + x64.

How to use DLL files from vkd3d-proton in Wine?
by zhengxianwei 22 Nov '24

22 Nov '24

I am a beginner with Wine and currently using it to run Photoshop 23. I noticed that vkd3d seems to lack support for Tiled Resource, which causes Photoshop’s compatibility check to fail in displaying the correct GPU information. I found that vkd3d-proton appears to implement this feature, so I compiled vkd3d-proton and copied the resulting d3d12.dll and d3d12core.dll directly into Wine’s directory. I also ensured that the required d3d12.dll was loaded correctly. However, when launching Photoshop, it crashes when using certain swapchain features. Setting aside the swapchain crash for now, is my approach of directly using the d3d12.dll generated by vkd3d-proton correct?

Folks, In our grand tradition of shaming people into doing work, after the Regressions page I'm proud to present the Pending Reviews page: https://source.winehq.org/reviews As with the regressions page, the goal should be to *not* be number one on the list. But feel free to congratulate Huw anyway ;-) Note that the list is a little overestimated, commenting on the diff counts as a review but simply adding a note doesn't, so you may see some MRs in your list that you have actually commented on already. If people find this thing useful we can try to make it smarter. Feedback is welcome! -- Alexandre Julliard julliard(a)winehq.org

Release plans
by Alexandre Julliard 31 Oct '24

31 Oct '24

Folks, Since there has been little activity this week, and I'm travelling on Friday, I'm going to delay Wine 9.21 until next Friday, November 8. There will then be a 9.22 release two weeks later, and two weeks after that, on December 6, the 10.0-rc1 release will mark the beginning of our annual code freeze period. As usual, the freeze will last until the final 10.0 is released sometime around mid-January. -- Alexandre Julliard julliard(a)winehq.org

Re: Helping Wine use 64 bit Mesa OGL drivers for 32-bit Windows applications
by Derek Lesho 31 Oct '24

31 Oct '24

Hi Christian, Thanks for exploring this option, it's great to have a better understanding of the capabilities/limits of mremap. First, a few practical questions: - How would Wine detect the updated mremap, I suppose we would want to create a test persistent mapping on init and see if mremap works on that page? - In my experience Mesa will sometimes return malloc'd pointers from glMapBuffer when using the transfer helper, which I assume has to do with buffer textures. If wine blindly uses remap for all glMapBuffer calls, we'll then end up hitting the private anonymous path, where from what I understand page faults are use to preserve the old page, potentially slowing things down, thoughts? Second, in regards to going forward: I don't have the final call on what path we end up taking 😅. I think it would be good if others from wine-devel pitched into what they think, but here's my opinion: I think the mremap approach should definitely be pursued since it looks like such a simple Kernel patch, but it may also be good to pursue a simple Mesa-Integrated path as well, maybe with Mesa calling into a Wine library to allocate 32-bit pages, as we support non-linux OS's as well.

In my last mail I responded to this approach all the way at the bottom, so it probably got lost: mremap on Linux as it exists now won't work as it only supports private anonymous mappings (in conjunction with MREMAP_DONTUNMAP), which GPU mappings are not.
