Please send your change to [the main repository](https://github.com/hexops/mach/tree/main/libs/gpu) instead, sorry for the trouble!
|
||||
|
||||
This helps us avoid some complex merge conflicts we run into when changes are made to both repositories and history needs to be reconciled. Keeping PRs in just that repository enables us to use `git subtree` to trivially keep the two repositories in sync.
|
||||
|
||||
Once your PR is merged over there, it'll automatically sync to this repository.

|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.

8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||

# mach/gpu: the WebGPU interface for Zig
|
||||
|
||||
`mach/gpu` provides a truly cross-platform graphics API for Zig (desktop, mobile, and web) with unified low-level graphics & compute backed by Vulkan, Metal, D3D12, and OpenGL (as a best-effort fallback.)
|
||||
|
||||
## Examples
|
||||
|
||||
See [the mach/gpu examples showcase](https://machengine.org/gpu) for more information.
|
||||
|
||||
## Features
|
||||
|
||||
* Desktop, Steam Deck, (soon) web, and (future) mobile support.
|
||||
* A modern graphics API similar to Metal, Vulkan, and DirectX 12.
|
||||
* Cross-platform shading language
|
||||
* Compute shaders
|
||||
* Seamless cross-compilation & zero-fuss installation, as with all Mach libraries.
|
||||
* Advanced GPU features where hardware support is available, such as:
|
||||
* Depth buffer clip control
|
||||
* Special depth/stencil format with 32 bit floating point depth and 8 bits integer stencil.
|
||||
* Timestamp queries
|
||||
* Pipeline statistics queries
|
||||
* Texture compression (BC, ETC2, and ASTC)
|
||||
* Indirect first-instance
|
||||
* Depth clamping
|
||||
* Shader 16-bit float support
|
||||
* Multi planar formats
|
||||
|
||||
## Benefits of mach/gpu and WebGPU
|
||||
|
||||
`mach/gpu` is a zero-cost idiomatic Zig interface to [the next-generation WebGPU API](https://www.w3.org/TR/webgpu/), which supersedes WebGL and exposes the common denominator between the latest low-level graphics APIs (Vulkan, Metal, D3D12) in the web.
|
||||
|
||||
Despite its name, [WebGPU was built with native support in mind](http://kvark.github.io/web/gpu/native/2020/05/03/point-of-webgpu-native.html) and has substantial investment from Mozilla, Google, Microsoft, Intel, and Apple.
|
||||
|
||||
When targeting WebAssembly, `mach/gpu` merely calls into the browser's native WebGPU implementation.
|
||||
|
||||
When targeting native platforms, we build Google Chrome's WebGPU implementation, [Dawn](https://dawn.googlesource.com/dawn) using Zig as the C/C++ compiler toolchain. We bypass the client-server sandboxing model, and use `zig build` (plus a lot of hand-holding) to support zero-fuss cross compilation & installation without any third-party Google tools, libraries, etc. Just `zig` and `git` needed, nothing else.
|
||||
|
||||
## Perfecting WebGPU for Zig
|
||||
|
||||
There is a detailed write-up of how we've been [perfecting WebGPU for Zig](https://devlog.hexops.com/2022/perfecting-webgpu-native).
|
||||
|
||||
## Usage
|
||||
|
||||
`mach/gpu` can be used in three ways:
|
||||
|
||||
### "I want to do _everything_ myself"
|
||||
|
||||
This involves creating a window (using GLFW, and other APIs if you want Web, Mobile, or other platform support), using Dawn's API to create a device and bind it to that window, using OS-specific APIs to get the window handle to bind, etc.
|
||||
|
||||
`examples/main.zig` demonstrates how to do this. There's a fair amount of setup code involved. You might instead want to consider _Mach core_:
|
||||
|
||||
### Mach core: "I want a window, input & the WebGPU API - nothing else."
|
||||
|
||||
**Mach core** can be thought of as an alternative to SDL or GLFW:
|
||||
|
||||
* Mach handles creating a window, giving you user input, and gives you the WebGPU API for every platform.
|
||||
* You give Mach an `init`, `deinit` and `update` function for your app which will be called every frame.
|
||||
* As we add support for more platforms (browser, mobile, etc.) in the future, you get them for free because _Mach core_ is _truly cross platform_.
|
||||
|
||||
### "I want a full game engine"
|
||||
|
||||
`mach/gpu` is the graphics abstraction used by _Mach engine_, but we're not there yet. See https://machengine.org for more information.

Issues are tracked in the [main Mach repository](https://github.com/hexops/mach/issues?q=is%3Aissue+is%3Aopen+label%3Agpu).
|
||||
|
||||
## Contributing
|
||||
|
||||
Contributions are very welcome. Pull requests must be sent to [the main repository](https://github.com/hexops/mach/tree/main/libs/gpu) to avoid some complex merge conflicts we'd get by accepting contributions in both repositories. Once the changes are merged there, they'll get sync'd to this repository automatically.
|
||||
|
||||
## Goals
|
||||
|
||||
* Allow comptime-defined interception of WebGPU API requests (comptime interfaces.)
|
||||
* Expose a standard Dawn `webgpu.h`-compliant C ABI, which routes through Zig comptime interfaces.
|
||||
* Support Dawn and Browser (via WASM/JS) implementations of WebGPU.
|
||||
* Broad platform support: desktop, mobile, web, consoles.
|
||||
* First-class Linux support (Wayland, OpenGL and OpenGL ES fallbacks, etc.)
|
||||
|
||||
## Non-goals
|
||||
|
||||
* Support non-Dawn (e.g. Rust WebGPU) implementations if they don't match the same `webgpu.h` as Dawn.
|
||||
* Maintain backwards compatibility with deprecated `webgpu.h` methods.
|
||||
|
||||
## Quality of life improvements
|
||||
|
||||
We make the following quality of life improvements.
|
||||
|
||||
### Flag sets
|
||||
|
||||
See [perfecting WebGPU for Zig](https://devlog.hexops.com/2022/perfecting-webgpu-native).
|
||||
|
||||
### Optionality & nullability
|
||||
|
||||
* Optional values default to their zero value (either `null` or a struct constructor `.{}`) when specified as `optional` in `dawn.json`. This means things like `label`, `next_in_chain`, etc. do not need to be specified.
|
||||
* Fields representing a slice with a `_count` field are nullable pointers defaulting to null and 0 by default.
|
||||
|
||||
### Slice helpers
|
||||
|
||||
Some WebGPU APIs expose slices as pointers and lengths, we either wrap these to provide a slice or alter the method directly to provide a slice (if little overhead.) The original C-style API can always be accessed via the `gpu.Impl` type in any case.
|
||||
|
||||
The slice helpers are:
|
||||
|
||||
* `Adapter.enumerateFeaturesOwned`
|
||||
* `Buffer.getConstMappedRange`
|
||||
* `Buffer.getMappedRange`
|
||||
* `CommandEncoder.writeBuffer`
|
||||
* `ComputePassEncoder.setBindGroup`
|
||||
* `Device.enumerateFeaturesOwned`
|
||||
* `Queue.writeTexture`
|
||||
* `Queue.writeBuffer`
|
||||
* `RenderPassEncoder.executeBundles`
|
||||
* `RenderBundleEncoder.setBindGroup`
|
||||
* `RenderPassEncoder.setBindGroup`
|
||||
|
||||
And, to initialize data structures with slices in them, the following helpers are provided:
|
||||
|
||||
* `BindGroupLayout.Descriptor.init`
|
||||
* `BindGroup.Descriptor.init`
|
||||
* `dawn.TogglesDescriptor.init`
|
||||
* `Device.Descriptor.init`
|
||||
* `PipelineLayout.Descriptor.init`
|
||||
* `QuerySet.Descriptor.init`
|
||||
* `RenderBundleEncoder.Descriptor.init`
|
||||
* `Texture.Descriptor.init`
|
||||
* `ComputePassDescriptor.init`
|
||||
* `RenderPassDescriptor.init`
|
||||
* `ProgrammableStageDescriptor.init`
|
||||
* `VertexBufferLayout.init`
|
||||
* `VertexState.init`
|
||||
* `FragmentState.init`
|
||||
* `CompilationInfo.getMessages`
|
||||
|
||||
### Typed callbacks
|
||||
|
||||
Most WebGPU callbacks provide a way to provide a `userdata: *anyopaque` pointer to the callback for context. We alter these APIs to expose a typed context pointer instead (again, the original API is always available via the `gpu.Impl` type should you want it):
|
||||
|
||||
* `Instance.requestAdapter`
|
||||
* `Adapter.requestDevice`
|
||||
* `Queue.onSubmittedWorkDone`
|
||||
* `Buffer.mapAsync`
|
||||
* `ShaderModule.getCompilationInfo`
|
||||
* `Device.createComputePipelineAsync`
|
||||
* `Device.createRenderPipelineAsync`
|
||||
* `Device.popErrorScope`
|
||||
* `Device.setDeviceLostCallback`
|
||||
* `Device.setLoggingCallback`
|
||||
* `Device.setUncapturedErrorCallback`
|
||||
|
||||
### next_in_chain extension type safety
|
||||
|
||||
WebGPU exposes struct types which are extendable arbitrarily, often by implementation-specific extensions. For example:
|
||||
|
||||
```zig
|
||||
const extension = gpu.Surface.DescriptorFromWindowsHWND{
|
||||
.chain = gpu.ChainedStruct{.next = null, .s_type = .surface_descriptor_from_windows_hwnd},
|
||||
.hinstance = foo,
|
||||
.hwnd = bar,
|
||||
}
|
||||
const descriptor = gpu.Surface.Descriptor{
|
||||
.next_in_chain = @ptrCast(?*const ChainedStruct, &extension),
|
||||
};
|
||||
```
|
||||
|
||||
Here `gpu.Surface.Descriptor` is a concrete type. The `next_in_chain` field is set to an arbitrary pointer which follows the `gpu.ChainedStruct` pattern: it must begin with a `gpu.ChainedStruct` where the `s_type` identifies which fields may follow after, and `.next` could theoretically chain more extensions on too.
|
||||
|
||||
Complexity aside, `next_in_chain` is not type safe! It cannot be, because such an extension could be implementation-specific. To make this safer, we instead change the `next_in_chain` field type to be a union, where one option is the type-unsafe `generic` pointer, and the other options are known extensions:
|
||||
|
||||
```zig
|
||||
pub const NextInChain = extern union {
|
||||
generic: ?*const ChainedStruct,
|
||||
from_windows_hwnd: *const DescriptorFromWindowsHWND,
|
||||
// ...
|
||||
};
|
||||
```
|
||||
|
||||
Additionally we initialize `.chain` with a default value, making our earlier snippet look like this in most cases:
|
||||
|
||||
```zig
|
||||
const descriptor = gpu.Surface.Descriptor{
|
||||
.next_in_chain = .{.from_windows_hwnd = &.{
|
||||
.hinstance = foo,
|
||||
.hwnd = bar,
|
||||
}},
|
||||
}
|
||||
```
|
||||
|
||||
### Others
|
||||
|
||||
* `Device.createShaderModuleWGSL` (helper to create WGSL shader modules more nicely)
|
||||
|
||||
There may be other opportunities for helpers, to improve the existing APIs, or add utility APIs on top of the existing APIs. If you find one, please open an issue we'd love to consider it.
|
||||
|
||||
## WebGPU version
|
||||
|
||||
Dawn's `webgpu.h` is the **authoritative source** for our API. You can find [the current version we use here](https://github.com/hexops/dawn/blob/generated-2023-06-30.1688174725/out/Debug/gen/include/dawn/webgpu.h).
|
||||
|
||||
## Development rules
|
||||
|
||||
The rules for translating `webgpu.h` are as follows:
|
||||
|
||||
* `WGPUBuffer` -> `gpu.Buffer`:
|
||||
* Opaque pointers like these become a `pub const Buffer = opaque {_}` to ensure they are still pointers compatible with the C ABI, while still allowing us to declare methods on them.
|
||||
* As a result, a `null`able `Buffer` is represented simply as `?*Buffer`, and any function that would normally take `WGPUBuffer` now takes `*Buffer` as a parameter.
|
||||
* `WGPUBufferBindingType` -> `gpu.Buffer.BindingType` (purely because it's prefix matches an opaque pointer type, it thus goes into the `Buffer` opaque type.)
|
||||
* Reserved Zig keywords are translated as follows:
|
||||
* `error` -> `err`
|
||||
* `type` -> `typ`
|
||||
* `opaque` -> `opaq`
|
||||
* Constant names map using a few simple rules, but it's easiest to describe them with some concrete examples:
|
||||
* `RG11B10Ufloat -> rg11_b10_ufloat`
|
||||
* `Depth24PlusStencil8 -> depth24_plus_stencil8`
|
||||
* `BC5RGUnorm -> bc5_rg_unorm`
|
||||
* `BC6HRGBUfloat -> bc6_hrgb_ufloat`
|
||||
* `ASTC4x4UnormSrgb -> astc4x4_unorm_srgb`
|
||||
* `maxTextureDimension3D -> max_texture_dimension_3d`
|
||||
* Sometimes an enum will begin with numbers, e.g. `WGPUTextureViewDimension_2DArray`. In this case, we add a prefix so instead of the enum field being `2d_array` it is `dimension_2d_array` (an enum field name must not start with a number in Zig.)
|
||||
* Dawn extension types `WGPUDawnFoobar` are placed under `gpu.dawn.Foobar`
|
||||
* Regarding _"undefined"_ terminology:
|
||||
* In Zig, _undefined_ usually means _undefined memory_, _undefined behavior_, etc.
|
||||
* In WebGPU, _undefined_ commonly refers to JS-style undefined: _an optional value that was not specified_
