[PATCH v2 0/5] MR9116: win32u: Implement WGL_WINE_query_renderer extension for EGL driver
wined3d relies on `WGL_WINE_query_renderer` to get information about current render. The issue is that EGL driver does not implement this extension, which often leads to troubles for wined3d in trying to apply their quirks based only on a `GL_RENDERER` string. Because VRAM size becomes unknown, wined3d refuses to render due to "lack of memory". This MR solves the issue by implementing `WGL_WINE_query_renderer` for EGL driver.
In EGL there's no extension like `GLX_MESA_query_renderer`, so we have to implement it ourselves.
Some caveats of this implementation:
- Obtaining some attributes involves context switching for direct quries to OpenGL driver. I tried to avoid risk of situation where we might lose current driver context, and from my tests it works, but maybe I’m missing something.
- Getting vendor and device PCI IDs is done through DRM, which is a bit tricky at the moment as we have to go through devfs. This can be made cleaner through libdrm, but I don’t think we should introduce a new dependency just for a few attributes.
- The `GL_NVX_gpu_memory_info` extension is used for VRAM size. It is quite common but not supported everywhere, unfortunately there is no simpler way to get information about VRAM.
- There is no API for `WGL_RENDERER_UNIFIED_MEMORY_ARCHITECTURE_WINE`. Same as for winemac.drv, but it’s not a big problem since it doesn’t seem to be used now.
Some advantages:
- Unlike GLX, we are not tied to Mesa specific extensions, which allows it to work for NVIDIA as well, sparing wined3d from having to guess something based only on the GPU name.
- Unlike the same GLX, we can actually query multiple devices. Although `GLX_MESA_query_renderer` also proclaims this, in fact Mesa does not implement anything other than queries to the current renderer: https://gitlab.freedesktop.org/mesa/mesa/-/blob/32a10ccbdd1e6750c84aac3393dc...
Hope I didn’t miss anything.

v2: Fixed build warnings
As far as I can tell WineD3D only ever calls wglQueryCurrentRenderer* functions and not the indexed ones ever, so I doesn't seem useful to implement the indexed renderer queries.
Also, one question is how we can match that the current renderer is the default (device index 0) one. There doesn't seem to be any guarantee that this is the case?

Yes, that’s true, and I originally wanted to implement only wglQueryCurrentRenderer*, but I wasn’t sure if it was the right way to implement just a part of extension functions and whether it would be accepted, so I decided to implement it completely.
If this is acceptable, then I can remake MR, it could greatly simplify the code.

I’m not sure if there is any consensus about this, as far as I know the NVIDIA driver accurately creates a default display always for zero-indexed device (https://github.com/NVIDIA/egl-gbm/blob/main/src/gbm-display.c#L206, https://github.com/NVIDIA/egl-gbm/blob/main/src/gbm-display.c#L139-L143). I’m not sure about Mesa, because their EGL code is quite confusing, but I understand that they also expect to use the zero-indexed device as default and this is confirmed in practice (https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/egl/main/egldevice....).
Anyway, it's valid concern, so we can query the default display device through `eglQueryDisplayAttribEXT` with no need to iterate over all devices.
