Incompatibility with rust wayland-client crate #34

Closed wez closed 7 months ago

wez commented 3 years ago

When trying to run wezterm under Wayland, EGL initialization fails with BAD_NATIVE_WINDOW.

Getting this under a debugger, it looks like this runtime check is the critical piece:

#1  wlEglIsWaylandWindowValid (window=window@entry=0x55555a44f740) at ../src/wayland-eglsurface.c:74
74          return WL_CHECK_INTERFACE_TYPE(surface, wl_surface_interface);

Poking around at the surface that was passed in:

>>> p surface
$5 = (struct wl_surface *) 0x555559938800
>>> p *(void**)surface
$8 = (void *) 0x555559904ea8 <wayland_client::protocol::wl_surface::wl_surface_interface>
>>> p *(struct wl_interface*)0x555559904ea8
$12 = {
  name = 0x555558d3994c "wl_surface",
  version = 4,
  method_count = 10,
  methods = 0x555559904d78 <wayland_client::protocol::wl_surface::wl_surface_requests>,
  event_count = 2,
  events = 0x555559904e78 <wayland_client::protocol::wl_surface::wl_surface_events>
}

And comparing with the wl_surface type that is checked against by this part of the macro:

https://github.com/NVIDIA/egl-wayland/blob/9c9c4c684983f7b0821f516f8821118170a785ea/include/wayland-eglutils.h#L60

>>> p &wl_surface_interface
$13 = (const struct wl_interface *) 0x7ffff7d4aa00 <wl_surface_interface>
>>> p wl_surface_interface
$14 = {
  name = 0x7ffff7d46a88 "wl_surface",
  version = 4,
  method_count = 10,
  methods = 0x7ffff7d4a540 <wl_surface_requests>,
  event_count = 2,
  events = 0x7ffff7d4a500 <wl_surface_events>
}

The interface appears to be compatible if the check were to perform a comparison of what's inside the wl_interface, even though the addresses are not identical.

Why aren't the addresses identical?

The rust client implementation employs code generation to produce most of its code; here's an example of the definition of that particular interface:

https://docs.rs/wayland-client/0.28.1/src/wayland_client/opt/rustwide/target/debug/build/wayland-client-fdd09ed62affdce6/out/wayland_api.rs.html#5885-5892

The rust client does, however, call out to the system libraries so that it should be comptible with EGL libraries. This same code runs fine when run against the nouveau driver.

So! Should NVIDIA/egl-wayland project be performing a deeper wl_interface comparison here to unblock this usage?

wez commented 3 years ago

this comment https://github.com/Smithay/wayland-rs/issues/374#issuecomment-778716363 suggests expanding the pointer check in the same way that libwayland's wl_interface_equal function works.

erik-kz commented 3 years ago

Thanks for the detailed report. I agree we should fall back to checking the interface name if the pointer check fails. The only tricky thing is that we try to be safe about dereferencing the pointer (currently by calling mincore), however we should be able to work something out.

As this is blocking all other Rust-based OpenGL applications I know (e.g., Alacritty or glutin-based applications in general), is there any progress on this @erik-kz ?

erik-kz commented 3 years ago

A fix is under internal code-review at NVIDIA, should be able to get pushed within the next few days. Apologies for the delay.

erik-kz commented 3 years ago

Should be fixed by https://github.com/NVIDIA/egl-wayland/commit/2eb4628d64a8297fb4c08aa796fdf33ff54a670f Again, sorry sorry sorry this took so damned long. Note that there are a few more changes to this library coming in the next few days, so I'm going to wait to those to land, but will bump the release as soon as they do.

colemickens commented 3 years ago

Has this shipped in the egl-wayland used in NVIDIA releases now?

cubanismo commented 3 years ago

I believe the first release to include this will be the 495 series beta release, due some time next week if all goes to plan.

wgpu's code disables presentation for the platform because it detects something wrong with EGL support. If I edit the check, there are BAD_NATIVE_WINDOW errors appearing. Some discussions here.

And when running winit examples, the code didn't report errors but there are no windows visible on the screen, only icons on the desktop dock.

It seems that there is still incompatibility among the driver and rust wayland-client crate. Could Nvidia do more to improve this? Thanks!

erik-kz commented 3 years ago

Interesting, thanks for the report. The interface check that was behind the original issue should be fixed, so I suspect this has a different root-cause, but will definitely look into it. Re-opening the issue.

erik-kz commented 3 years ago

@VitalyAnkh can you confirm that you have the latest version of the egl-wayland library installed along with the 495 beta driver? Depending on your distribution it might be packaged separately.

I tried running the wgpu shadow example, and with the default vulkan back-end it worked as expected. If I set WGPU_BACKEND=gl I do get the "No suitable GPU adapters" error you mentioned in https://github.com/gfx-rs/wgpu/issues/1787#issuecomment-945001343 and if I hack the tier_max check as you did I instead get EGL_BAD_ATTRIBUTE from eglCreatePlatformWindowSurface. I'm not seeing any EGL_BAD_NATIVE_WINDOW errors, though.

The reason for the EGL_BAD_ATTRIBUTE error is that wgpu sets EGL_RENDER_BUFFER to EGL_SINGLE_BUFFER, which we reject in the validateSurfaceAttrib function in wayland-eglsurface.c. I'll look into whether this is expected and get back to you.

VitalyAnkh commented 3 years ago

@erik-kz Thanks! Really excited with your kind reply. I did install the lastest version of egl-wayland:

pacman -Q | rg egl-wayland
egl-wayland-git 1.1.9.r0.gcd0d19a-1

and latest Nvidia 495 driver:

pacman -Q | rg nvidia
lib32-nvidia-cg-toolkit 3.1-7
lib32-nvidia-utils-beta 495.44-1
lib32-opencl-nvidia-beta 495.44-1
nvidia-beta-dkms 495.44-1
nvidia-cg-toolkit 3.1-6
nvidia-utils-beta 495.44-1
opencl-nvidia-beta 495.44-1

and I can confirm the driver is running:

I think this is an interesting point for you could run this example as expected. All I expect is running this example under wayland with vulkan/gl backend successfully. I don't know if it's my system's fault or something else.

If I set WGPU_BACKEND=gl I got the same "No suitable GPU adapters" error as you. After hacking the tier_max check I got the same results as you, no EGL_BAD_NATIVE_WINDOW any more, only EGL_BAD_ATTRIBUTE errors. This is the output after hacking the check:

In conclusion, it's the best result I expect that nvidia driver supports vulkan under wayland with rust's wayland crate. I found it doesn't, but you tested without issues. I will try confirming if this is happening to others using nvidia 495 drivers users and wayland.

erik-kz commented 3 years ago

Can you check if the file /usr/lib/libnvidia-vulkan-producer.so is present on your system? I think the issue might be that the Arch Linux nvidia-utils package doesn't include it.

VitalyAnkh commented 3 years ago

@erik-kz It's true that the file /usr/lib/libnvidia-vulkan-producer.so is not present on my system. Should we help Arch Linux fix this? :smiley:

VitalyAnkh commented 3 years ago

I add the following line to the PKGBUILD of the AUR package nvidia-utils-beta:

    # vulkan
    install -D -m755 "libnvidia-vulkan-producer.so.${pkgver}" -t "${pkgdir}/usr/lib"

then makepkg si, now the file /usr/lib/libnvidia-vulkan-producer.so is in my system now:

file /usr/lib/libnvidia-vulkan-producer.so.495.44

But running the wgpu example I still got errors:

Besides, I can't build egl-wayland-git on my system now, so the latest commits of egl-wayland is not installed. When building I got this:

Does this matter?

erik-kz commented 3 years ago

Dang it, the commit I pushed this morning broke the public build. Sorry about that. I'll get that fixed ASAP. As a work-around, you could add "git checkout 1.1.9" to the PKGBUILD.

Anyway, I filed https://bugs.archlinux.org/task/72560 for the Arch Linux package. issue Could you try running "ln -s /usr/lib/libnvidia-vulkan-producer.so.495.44 /usr/lib/libnvidia-vulkan-producer.so"? I think that symlink also needs to exist.

VitalyAnkh commented 3 years ago

Thanks! I add the symlink then the wgpu examples start running! But if the mouse hovers on them, the window runs very slowly and not responding sometimes. It seems not the driver's fault. Maybe rust's GUI library needs some improvements. Alacritty and some other rust GUI apps also experience input latency AFAIK. Anyway it worked! Thanks for your help!

Heads-up.

If you're using nvidia drivers on Debian, you may encounter:

This happened when I tried executing https://github.com/bevyengine/bevy examples.

This was also solved by the "symlink" solution above: https://github.com/NVIDIA/egl-wayland/issues/34#issuecomment-953176437

More specifically I ran:

sudo ln -s /usr/lib/x86_64-linux-gnu/nvidia/current/libnvidia-vulkan-producer.so.525.147.05 /usr/lib/libnvidia-vulkan-producer.so
