           Summary: dozen Vulkan driver fails due to missing/minimal
                    dxcore implementation (both MacOS and Linux)..
           Product: Wine
           Version: 10.6
          Hardware: x86-64
                OS: Linux

Hi,
in brief my request expand dxcore.dll support in Wine to a minimal dxcore
implementation that allows to run Dozen via Wine.. on both Macos and Linux..
on MacOS for Dozen+D3DMetal testing on Linux for Dozen+VKD3D testing..

details:
just wanting to test Dozen (Mesa Vulkan over D3D12 library) in Macos with
Crossover 25.0 (bottle setup to using D3DMetal 2.1 as D3D12 driver)..
for that I just download:
mesa3d-25.0.4-release-msvc.7z 
from:
https://github.com/pal1000/mesa-dist-win/releases/tag/25.0.4

and then adjust ICD loader to find the vulkan_dzn.dll driver and run
vulkaninfo.exe..
I check I have all enviroment correctly as also extract lavapipe Vulkan driver
from that package and it works correctly with vulkaninfo.exe

using dozen on Crossover 25.0 (setup to use D3DMetal 2.1) I see bug that is not
related to D3DMetal D3D12 driver:
MESA: error: Failed to retrieve D3D12GetInterface
MESA: error: Failed to create DXCore adapter factory

so would fail also on Linux..

seeing Dozen source code I find in:

https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/microsoft/vulkan/dz...
fails in dzn_enumerate_physical_devices_dxcore function.. code below..

that is using dxcore and fails with DXCoreCreateAdapterFactory being a stub
currently:
https://github.com/wine-mirror/wine/blob/master/dlls/dxcore/main.c

perhaps it's better to use as reference if wanting to implement dxcore Wine
support checking it works with a minimal sample provided "Minimal DXCore
application":
https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/dxcore/dxcore-s...

dxcore microsoft docs:
https://learn.microsoft.com/en-us/windows/win32/dxcore/dxcore-enum-adapters

dxcore seems the "future" to enumerate adapters on Windows due to enumeration
possibly NPU devices also..

dozen source code where it fails:

util_dl_library *dxcore = util_dl_open(UTIL_DL_PREFIX "dxcore" UTIL_DL_EXT);
   if (!dxcore) {
      mesa_loge("Failed to load DXCore\n");
      return VK_ERROR_INITIALIZATION_FAILED;
   }

using PFNDXCoreCreateAdapterFactory = HRESULT (APIENTRY*)(REFIID, void **);
   PFNDXCoreCreateAdapterFactory create_func =
(PFNDXCoreCreateAdapterFactory)util_dl_get_proc_address(dxcore,
"DXCoreCreateAdapterFactory");
   if (!create_func) {
      mesa_loge("Failed to load DXCoreCreateAdapterFactory\n");
      return VK_ERROR_INITIALIZATION_FAILED;
   }

IDXCoreAdapterFactory *factory;
   if (FAILED(create_func(IID_PPV_ARGS(&factory)))) {
      mesa_loge("Failed to create DXCore adapter factory\n");
      return VK_ERROR_INITIALIZATION_FAILED;
   }
