How to enable web GPU when build Chromium

[Hưng Phạm]

When building Chromium v127, I ran this JavaScript command in the console:

navigator.gpu.requestAdapter({ powerPreference: "high-performance" });

But the result returned is "No available adapters," which causes an error when accessing https://toji.github.io/webgpu-test/. I have tried flags like --enable-unsafe-webgpu --enable-features=Vulkan,UseSkiaRenderer, but they did not fix the issue.

Meanwhile, the same version in Chrome returns different information.

How can I build Chromium to use WebGPU?

Thank you very much.
