Bug ID: 51662
           Summary: Wine was built without libvkd3d-shader support.
           Product: Wine
           Version: 6.0.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

      Distribution: ---

Attempting to run a test program that uses Vulkan. The program is "cube.exe"
from WGPU; it's just a basic test to see if Vulkan graphics work.

Set the renderer=vulkan registry key under Direct3d with wine regedit per
release notes.

Error message and backtrace from Wine crash

Ubuntu 20.04 LTS

Attempting to test WGPU cross-compiling under Wine. This is the simplest WGPU
program with graphical output,and is a standard example provided with WGPU.
It was cross-compiled on Linux using Rust, with target x86_64-pc-windows-gnu.

Ubuntu 20.04 (and 21.04) only have the libvkd3d-1.1 distro package. This means
it is built pre- libvkd3d-shader.

If you want wine with "full" vkd3d support - from vkd3d-1.2, you need to either
install libvkd3d from a PPA and build yourself, or wait for distro packages
being updated (not very likely for 20.04/21.04 tbh)

It fails with executable Wine 6.0.1, downloaded from Wine's repository. I'm not
building Wine from source. There's nothing later than that other than a
development release.

Ref: https://www.winehq.org/

"Ubuntu 20.04 (and 21.04) only have the libvkd3d-1.1 distro package. This means
it is built pre- libvkd3d-shader."

This isn't a shader level problem. This is a GPU memory allocation problem. It
doesn't need the latest shaders.

The WGPU developers write, at

https://github.com/gfx-rs/wgpu/issues/1854#issuecomment-904087026

"Also the log has this:

fixme:d3d12_device_CheckFeatureSupport: Unhandled feature 0x12.
    Using NVIDIA GeForce GTX 470 (Dx12)
    fixme:vkd3d_select_memory_type: Custom heaps not supported yet.

So it looks like vkd3d doesn't like some of the feature support queries and the
fact we are using custom heaps. This is clearly a bug in vkd3d, not wgpu."

So, Wine people, here's the WGPU bug report.

I'm rather confused; are you reporting a bug for a Direct3D 11 application or a
Direct3D 12 application? Comment 0 suggests the former, in which case you're
indeed running into limitations based on an old build of libvkd3d, but then in
comment 3 you say the latter.

Can you please give exact reproduction instructions?

Repro steps

Install current Rust on Ubuntu Linux (20.04 LTS used).
    Install current Wine (6.0.1) or use Wine 5 that ships with 20.04 LTS.
    Install Rust target for x86_64-pc-windows-gnu
    Build WGPU examples for that target, debug mode.
    wine cube.exe
> I'm rather confused; are you reporting a bug for a Direct3D 11 application or a Direct3D 12 application?

I'm not sure what mode was selected. WGPU speaks Direct3D 11, and 12, Vulkan,
and OpenGL, selected at run time. (Plus WebGL and Metal if built for other
targets.) The intent is that WGPU handles the compatibility issues for the
user. There's some negotiation at startup. That negotiation may have have gone
badly.

See https://github.com/gfx-rs/wgpu, "Supported platforms".

Here's a compiled version of "cube.exe" (named wgpu-cube.exe because of a name
conflict.) Can you get that to run under any version of Wine?

It doesn't run in d3d12 or Vulkan mode (mostly because I don't have a working
Vulkan driver, though presumably the errors mentioned in comment 3 would apply
here as well). On the other hand, if I set WGPU_BACKEND=dx11 or disable
d3d12.dll and vulkan-1.dll, I get an error "No suitable GPU adapters found on
the system!", which also appears if I set WGPU_BACKEND=dx11 on Windows.

That makes sense. WGPU can use DX12 or Vulkan, but neither works yet in Wine.
WGPU doesn't yet support DX11 or OpenGL, both of which Wine supports.
So there's no overlap and no option works. I think.

How far away is Wine support for either DX12 or Vulkan?

Both d3d12 and Vulkan are supported in Wine. The latter is relatively quite
complete since we just delegate down to the host driver. The former has more
missing features, but actually in the git version both
D3D12_FEATURE_D3D12_OPTIONS2 and custom heaps are supported. In fact, I tested
using a different computer that supports Vulkan and has vkd3d git installed,
and both the d3d12 and Vulkan backends work.

What I don't understand is how you're getting wined3d messages, from comments 0
and 1. What exactly did you do to trigger that?

Right, but as far as I can tell the d3d11 backend of that cube sample simply
doesn't work. I.e. it doesn't work on Windows either, and in Wine I don't even
see it getting as far as making any d3d11 calls.

Successful run of program which supposedly does not run under Windows

Running on Windows 7 Pro, AMD_64.

Downloaded and unzipped the executable from the animats.com web site where I
put it because it's too big to upload to this board.

Yes, it runs under Windows, but not, as I said, using the d3d11 backend. I.e.
if you set WGPU_BACKEND=dx11 before running, it gives the same "no suitable GPU
adapters found" error as I get on Linux.

As a recap to my/our findings on that issue, i would conclude the follwing:

I think this is a WONTFIX/NOTOURBUG type of issue, since WineHQ dev's cant
really push distro's to provide newer systemlibs (vkd3d).

For now on Ubuntu:
1. You need libvkd3d_1.2 from a Ubuntu PPA
2. You need to build wine-devel-6.1 or newer with the above library to get
D3D12 support (Or you need to download unsupported pre-compiled non-system
.deb's from elsewhere.)
3. You need to run "winetricks d3dcompiler_47" (to install Microsoft
d3dcompiler) on the prefix to get the rust/wgpu samples to work.

I can do some more verification for this if needed, but I think that my
conclusion is that this is a "distro problem" and not a "winebug", since it
does seem to work if you do the above 3 steps.

Sounds reasonable?

PS. I will have a chat with the ubuntu package maintainer about this, since a
similar issue with a different system library was partially solved with the
switch to libFAudio back when... just to make wine-devel be built with D3D12
libs perhaps. TBD on that tho - no promise or anything :)
