Optimize JavaScript
Chromium contributors sped up WebGPU performance for GPUComputePassEncoder, GPURenderPassEncoder, and GPUCommandEncoder methods by reducing the overhead of making calls from generated code in V8 JavaScript engine to C++ handlers in Blink rendering engine. See issue chromium:1417558.
The following microbenchmark shows CPU time of calls from JavaScript decreasing from around 0.5 ms per 10K draws to around 0.3 ms per 10K draws, which is a 40% improvement.
getCurrentTexture() on unconfigured canvas throws InvalidStateError
Calling GPUCanvasContext getCurrentTexture() method on an unconfigured canvas now throws InvalidStateError instead of OperationError according to the WebGPU spec. See issue chromium:1424461.
const context = document.querySelector("canvas").getContext("webgpu");
context.getCurrentTexture(); // Throws InvalidStateError
WGSL updates
Zero-filled vectors of AbstractInt can now be written as vec2(), vec3(), and vec4(). See issue tint:1892. For example:
vec2()isvec2(0,0)vec3()isvec3(0,0,0)vec4()isvec4(0,0,0,0)
Dawn updates
Improving error messages
Descriptor labels for invalid objects are not being dropped anymore so that you can see them in error messages. See issue dawn:1771.
Add missing APIs for Node.js
The GPUAdapter::requestAdapterInfo() and GPUBuffer::getMapState() methods are now implemented for Node.js. See issue dawn:1761.
