[WebGPU] Vertex buffer support
https://bugs.webkit.org/show_bug.cgi?id=248071
<radar://101564178>
Reviewed by Dean Jackson.
Implement basic vertex buffer support which supports the rotating cube test
case.
Very preliminary bind group support is implemented, which only
supports 1 buffer of arbitrary size.
* Source/WebCore/Modules/WebGPU/GPUBuffer.cpp:
(WebCore::GPUBuffer::GPUBuffer):
(WebCore::GPUBuffer::getMappedRange):
(WebCore::GPUBuffer::unmap):
If the buffer is mappedAtCreation then the API allows for
writing to the mapped range even if the write flag is not set.
We need to store the JSC::ArrayBuffer too so we
can copy it back to the MTLBuffer when the client
calls GPUBuffer.unmap
* Source/WebCore/Modules/WebGPU/GPUBuffer.h:
* Source/WebGPU/WebGPU/BindGroup.mm:
(WebGPU::Device::createBindGroup):
Preliminary support for bind groups via tier2 argument
buffers which are substantially easier to implement as
the tier1 path was not functioning in my testing.
* Source/WebGPU/WebGPU/RenderPassEncoder.mm:
(WebGPU::RenderPassEncoder::setBindGroup):
(WebGPU::RenderPassEncoder::setVertexBuffer):
(WebGPU::RenderPassEncoder::setViewport):
Implement setting vertex buffer and bind groups.
* Source/WebKit/GPUProcess/graphics/WebGPU/RemoteBuffer.cpp:
(WebKit::RemoteBuffer::getMappedRange):
(WebKit::RemoteBuffer::unmap):
If the buffer is mappedAtCreation then the API allows for
writing to the mapped range even if the write flag is not set.
* Source/WebKit/GPUProcess/graphics/WebGPU/RemoteBuffer.h:
* Source/WebKit/GPUProcess/graphics/WebGPU/RemoteBuffer.messages.in:
* Source/WebKit/Shared/WebGPU/WebGPUBindGroupEntry.cpp:
(WebKit::WebGPU::ConvertToBackingContext::convertToBacking):
Need to pass along a valid identifier unless the auto-generated
serializer asserts.
* Source/WebKit/WebProcess/GPU/graphics/WebGPU/RemoteBufferProxy.cpp:
(WebKit::WebGPU::RemoteBufferProxy::getMappedRange):
Support getMappedRange API.
* Websites/webkit.org/demos/webgpu/hello-cube.html:
* Websites/webkit.org/demos/webgpu/scripts/hello-cube.js: Added.
(async helloCube.frameUpdate):
(async helloCube):
Use requestAnimationFrame to spin the cube.
