MCP: Bindless support

4

Let's start off with the simplest hlsl shader I can more or less come up with to do bindless support, which I would like to port to rust-gpu. Notice that...

Support headless testing on CI

10

@bjorn3 mentioned in https://github.com/EmbarkStudios/rust-gpu/issues/134#issuecomment-716101846 that [Mesa's LLVMpipe](https://docs.mesa3d.org/drivers/llvmpipe.html) can be a possibility for headlessCI testing. Did some quick investigation and LLVMpipe has traditionally supported OpenGL but has recently merged in early...

Ergonomic Rust CPU to Rust GPU / SPIRV bindings

4

This is a design issue to research and figure out how to the bindings between shaders and our Rust CPU code (native or WASM) should look like. How should resources...

API Design: StorageBuffers

4

# Summary This proposal attempts to address #232, #180, and #8. StorageBuffers, aka Buffer Blocks, are the primary inputs / outputs to compute shaders, though they can also be used...

Language feature: barriers

8

We want to have the same types of safety on the GPU as we do on the CPU. One of those areas that make it easy to introduce race conditions...

Investigate custom `repr` for GPU memory

6

A few options here: - Hack the compiler to just output the data layout that we want - Add `#[repr(std140)]` and `#[repr(std430)]` to the language frontend (maybe have better names...

Check can be disabled by specifying `skip-toolchain-check` feature on either `rustc_codegen_spirv` or `spirv_builder`

Refactor how rustc_codegen_spirv is compiled

6

# Summary `rustc_codegen_spirv` is compiled and discovered in a very hacky way. Cargo compiles `rustc_codegen_spirv` because it is inside `spirv-builder`'s Cargo.toml as a dependency, and then `spirv-builder` discovers the `rustc_codegen_spirv`'s...

Improve documentation to include visual of what example app should look like?

3

I was hoping to learn how to write rust-gpu shaders, so I was going through the tutorial, and have to run the CPU version on my old mac air. I...

Inliner->`mem2reg` can quadratically amplify already-exponential inlining (turning seconds into minutes).

1

We've known for a while that the existing inliner+`mem2reg` setup can lead to long compile times (e.g. #851), but we've never had a simple stress test to measure that behavior...
