webgpureport.org crashes servo

[sagudev]

Discussed in #30914

^{Originally posted by beaufortfrancois December 22, 2023}
When running Servo 0.0.1-5e8f70f with --pref dom.webgpu.enabled, it fails to render https://webgpureport.org/

Without the pref, it loads and simply says WebGPU is not supported.

Is this a known issue?

[sagudev]

Removing await navigator.gpu.requestAdapter({ forceFallbackAdapter: true }) makes it work.

Crash line is:

servo/components/script/script_thread.rs

Line 1498 in 1f0f50b

=> FromWebGPUServer(msg.unwrap()),

Actually this site works for me on both linux and windows. @beaufortfrancois you are using mac, right?

[beaufortfrancois]

I'm using macOS. I wonder if it crashes if the system doesn't have a fallback adapter, which is the case on my macBook machine.

But forcing fallback adapter helps? Could you try wgpu-info (you may need to install it with cargo install wgpu-info)

It's actually removing await navigator.gpu.requestAdapter({ forceFallbackAdapter: true }) that makes it work.

Does website works on firefox on your machine?

[beaufortfrancois]

When setting the gfx.webgpu.ignore-blocklist pref in about:config, Firefox Nightly works!

[sagudev]

Try setting RUST_LOG=trace and paste the output from servo terminal invocation (ex: RUST_LOG=debug ./servo --pref dom.webgpu.enabled https://webgpureport.org/).

I can also reproduce the same error with the javascript code below:

  const adapter = await navigator.gpu.requestAdapter();
  const device = await adapter.requestDevice({
    requiredLimits: { maxTextureDimension1D: 123456 },
  });

You can try it at https://red-triangle-webgpu.glitch.me/servo-issue-30915.html

Thanks, I can reproduce this on my computer. It's not exactly the same error but goes through same path (that we apparently handle badly).

script::dom::gpuadapter Could not get GPUDevice causes panic

[gterzian]

[2023-12-22T18:31:38Z WARN  constellation::constellation] Failed to send request adapter message on WebGPU channel
called `Result::unwrap()` on an `Err` value: RecvError (thread Script(1,1), at components/script/script_thread.rs:1498)

Properly handling this is part of #30895 (this issue is then more about "why is there no adapter returned on a Mac?")

[gterzian]

Actually this was another problem, pr opened...

[gterzian]

The crash is fixed by #30989

Note that the actual error happened here, and it returned [wgpu_core::instance::RequestAdapterError. ](https://docs.rs/wgpu-core/latest/wgpu_core/instance/enum.RequestAdapterError.html#variant.NotFound).

Why no adapter is found on a Mac M2 is perhaps an issue to file directly at https://github.com/gfx-rs/wgpu ?

[sagudev]

Why no adapter is found on a Mac M2 is perhaps an issue to file directly at https://github.com/gfx-rs/wgpu ?

I think not because, wgpu-info does found it. We probably need to re-review our backends choices or get for equivalent of gfx.webgpu.ignore-blocklist.
