v0.17.0 (2023-07-20)

This is the first release that featured wgpu-info as a binary crate for getting information about what devices wgpu sees in your system. It can dump the information in both human readable format and json.

Major Changes

This release was fairly minor as breaking changes go.

wgpu types now !Send !Sync on wasm

Up until this point, wgpu has made the assumption that threads do not exist on wasm. With the rise of libraries like wasm_thread making it easier and easier to do wasm multithreading this assumption is no longer sound. As all wgpu objects contain references into the JS heap, they cannot leave the thread they started on.

As we understand that this change might be very inconvenient for users who don't care about wasm threading, there is a crate feature which re-enables the old behavior: fragile-send-sync-non-atomic-wasm. So long as you don't compile your code with -Ctarget-feature=+atomics, Send and Sync will be implemented again on wgpu types on wasm. As the name implies, especially for libraries, this is very fragile, as you don't know if a user will want to compile with atomics (and therefore threads) or not.

By @daxpedda in #3691

Power Preference is now optional

The power_preference field of RequestAdapterOptions is now optional. If it is PowerPreference::None, we will choose the first available adapter, preferring GPU adapters over CPU adapters.

By @Aaron1011 in #3903

initialize_adapter_from_env argument changes

Removed the backend_bits parameter from initialize_adapter_from_env and initialize_adapter_from_env_or_default. If you want to limit the backends used by this function, only enable the wanted backends in the instance.

Added a compatible surface parameter, to ensure the given device is able to be presented onto the given surface.

- wgpu::util::initialize_adapter_from_env(instance, backend_bits);
+ wgpu::util::initialize_adapter_from_env(instance, Some(&compatible_surface));

Major changes

Shader Changes

type has been replaced with alias to match with upstream WebGPU.

- type MyType = vec4<u32>;
+ alias MyType = vec4<u32>;

TextureFormat info API

The TextureFormat::describe function was removed in favor of separate functions: block_dimensions, is_compressed, is_srgb, required_features, guaranteed_format_features, sample_type and block_size.

- let block_dimensions = format.describe().block_dimensions;
+ let block_dimensions = format.block_dimensions();
- let is_compressed = format.describe().is_compressed();
+ let is_compressed = format.is_compressed();
- let is_srgb = format.describe().srgb;
+ let is_srgb = format.is_srgb();
- let required_features = format.describe().required_features;
+ let required_features = format.required_features();

Additionally guaranteed_format_features now takes a set of features to assume are enabled.

- let guaranteed_format_features = format.describe().guaranteed_format_features;
+ let guaranteed_format_features = format.guaranteed_format_features(device.features());

Additionally sample_type and block_size now take an optional TextureAspect and return Options.

- let sample_type = format.describe().sample_type;
+ let sample_type = format.sample_type(None).expect("combined depth-stencil format requires specifying a TextureAspect");
- let block_size = format.describe().block_size;
+ let block_size = format.block_size(None).expect("combined depth-stencil format requires specifying a TextureAspect");

By @teoxoy in #3436

BufferUsages::QUERY_RESOLVE

Buffers used as the destination argument of CommandEncoder::resolve_query_set now have to contain the QUERY_RESOLVE usage instead of the COPY_DST usage.

  let destination = device.create_buffer(&wgpu::BufferDescriptor {
      // ...
-     usage: wgpu::BufferUsages::COPY_DST | wgpu::BufferUsages::MAP_READ,
+     usage: wgpu::BufferUsages::QUERY_RESOLVE | wgpu::BufferUsages::MAP_READ,
      mapped_at_creation: false,
  });
  command_encoder.resolve_query_set(&query_set, query_range, &destination, destination_offset);

By @JolifantoBambla in #3489

The following Features have been renamed.

• SHADER_FLOAT16 -> SHADER_F16
• SHADER_FLOAT64 -> SHADER_F64
• SHADER_INT16 -> SHADER_I16

• WRITE_TIMESTAMP_INSIDE_PASSES -> TIMESTAMP_QUERY_INSIDE_PASSES

By @teoxoy in #3534

Anisotropic Filtering

Anisotropic filtering has been brought in line with the spec. The anisotropic clamp is now a u16 (was a Option<u8>) which must be at least 1.

If the anisotropy clamp is not 1, all the filters in a sampler must be Linear.

SamplerDescriptor {
-    anisotropic_clamp: None,
+    anisotropic_clamp: 1,
}

By @cwfitzgerald in #3610.

TextureFormat Names

Some texture format names have changed to get back in line with the spec.

- TextureFormat::Bc6hRgbSfloat
+ TextureFormat::Bc6hRgbFloat

By @cwfitzgerald in #3671.

wgpu-0.15.0 (2023-01-25)

Major Changes

WGSL Top-Level let is now const

All top level constants are now declared with const, catching up with the wgsl spec.

let is no longer allowed at the global scope, only within functions.

-let SOME_CONSTANT = 12.0;
+const SOME_CONSTANT = 12.0;

See https://github.com/gfx-rs/naga/blob/master/CHANGELOG.md#v011-2023-01-25 for smaller shader improvements.

Surface Capabilities API

The various surface capability functions were combined into a single call that gives you all the capabilities.

- let formats = surface.get_supported_formats(&adapter);
- let present_modes = surface.get_supported_present_modes(&adapter);
- let alpha_modes = surface.get_supported_alpha_modes(&adapter);
+ let caps = surface.get_capabilities(&adapter);
+ let formats = caps.formats;
+ let present_modes = caps.present_modes;
+ let alpha_modes = caps.alpha_modes;

Additionally Surface::get_default_config now returns an Option and returns None if the surface isn't supported by the adapter.

- let config = surface.get_default_config(&adapter);
+ let config = surface.get_default_config(&adapter).expect("Surface unsupported by adapter");

Fallible surface creation

Instance::create_surface() now returns Result<Surface, CreateSurfaceError> instead of Surface. This allows an error to be returned if the given window is a HTML canvas and obtaining a WebGPU or WebGL 2 context fails. (No other platforms currently report any errors through this path.) By @kpreid in #3052

Queue::copy_external_image_to_texture on WebAssembly

A new api, Queue::copy_external_image_to_texture, allows you to create wgpu textures from various web image primitives. Specificically from HtmlVideoElement, HtmlCanvasElement, OffscreenCanvas, and ImageBitmap. This provides multiple low-copy ways of interacting with the browser. WebGL is also supported, though WebGL has some additional restrictions, represented by the UNRESTRICTED_EXTERNAL_IMAGE_COPIES downlevel flag. By @cwfitzgerald in #3288

Instance creation now takes InstanceDescriptor instead of Backends

Instance::new() and hub::Global::new() now take an InstanceDescriptor struct which cointains both the existing Backends selection as well as a new Dx12Compiler field for selecting which Dx12 shader compiler to use.

- let instance = Instance::new(wgpu::Backends::all());
+ let instance = Instance::new(wgpu::InstanceDescriptor {
+     backends: wgpu::Backends::all(),
+     dx12_shader_compiler: wgpu::Dx12Compiler::Fxc,
+ });

Instance now also also implements Default, which uses wgpu::Backends::all() and wgpu::Dx12Compiler::Fxc for InstanceDescriptor

- let instance = Instance::new(wgpu::InstanceDescriptor {
-     backends: wgpu::Backends::all(),
-     dx12_shader_compiler: wgpu::Dx12Compiler::Fxc,
- });
+ let instance = Instance::default();

By @Elabajaba in #3356

Texture Format Reinterpretation

The new view_formats field in the TextureDescriptor is used to specify a list of formats the texture can be re-interpreted to in a texture view. Currently only changing srgb-ness is allowed (ex. Rgba8Unorm <=> Rgba8UnormSrgb).

let texture = device.create_texture(&wgpu::TextureDescriptor {
  // ...
  format: TextureFormat::Rgba8UnormSrgb,
+ view_formats: &[TextureFormat::Rgba8Unorm],
});

let config = wgpu::SurfaceConfiguration {
  // ...
  format: TextureFormat::Rgba8Unorm,
+ view_formats: vec![wgpu::TextureFormat::Rgba8UnormSrgb],
};
surface.configure(&device, &config);

MSAA x2 and x8 Support

Via the TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES feature, MSAA x2 and x8 are now supported on textures. To query for x2 or x8 support, enable the feature and look at the texture format flags for the texture format of your choice.

By @39ali in 3140

DXC Shader Compiler Support for DX12

You can now choose to use the DXC compiler for DX12 instead of FXC. The DXC compiler is faster, less buggy, and allows for new features compared to the old, unmaintained FXC compiler.

You can choose which compiler to use at Instance creation using the dx12_shader_compiler field in the InstanceDescriptor struct. Note that DXC requires both dxcompiler.dll and dxil.dll, which can be downloaded from https://github.com/microsoft/DirectXShaderCompiler/releases. Both .dlls need to be shipped with your application when targeting DX12 and using the DXC compiler. If the .dlls can't be loaded, then it will fall back to the FXC compiler. By @39ali and @Elabajaba in #3356

Suballocate DX12 buffers and textures

The DX12 backend can now suballocate buffers and textures from larger chunks of memory, which can give a significant increase in performance (in testing a 100x improvement has been seen in a simple scene with 200 write_buffer calls per frame, and a 1.4x improvement in Bistro using Bevy).

Previously wgpu-hal's DX12 backend created a new heap on the GPU every time you called write_buffer (by calling CreateCommittedResource), whereas now it uses gpu_allocator to manage GPU memory (and calls CreatePlacedResource with a suballocated heap). By @Elabajaba in #3163

Backend selection by features in wgpu-core

Whereas wgpu-core used to automatically select backends to enable based on the target OS and architecture, it now has separate features to enable each backend:

• "metal", for the Metal API on macOS and iOS
• "vulkan", for the Vulkan API (Linux, some Android, and occasionally Windows)
• "dx12", for Microsoft's Direct3D 12 API
• "gles", OpenGL ES, available on many systems
• "dx11", for Microsoft's Direct3D 11 API

None are enabled by default, but the wgpu crate automatically selects these features based on the target operating system and architecture, using the same rules that wgpu-core used to, so users of wgpu should be unaffected by this change. However, other crates using wgpu-core directly will need to copy wgpu's logic or write their own. See the [target] section of wgpu/Cargo.toml for details.

Similarly, wgpu-core now has emscripten and renderdoc features that wgpu enables on appropriate platforms.

In previous releases, the wgpu-core crate decided which backends to support. However, this left wgpu-core's users with no way to override those choices. (Firefox doesn't want the GLES back end, for example.) There doesn't seem to be any way to have a crate select backends based on target OS and architecture that users of that crate can still override. Default features can't be selected based on the target, for example. That implies that we should do the selection as late in the dependency DAG as feasible. Having wgpu (and wgpu-core's other dependents) choose backends seems like the best option.

By @jimblandy in #3254.

wgpu-0.14.0 (2022-10-05)

Major Changes

@invariant Warning

When using CompareFunction::Equal or CompareFunction::NotEqual on a pipeline, there is now a warning logged if the vertex shader does not have a @invariant tag on it. On some machines, rendering the same triangles multiple times without an @invariant tag will result in slightly different depths for every pixel. Because the *Equal functions rely on depth being the same every time it is rendered, we now warn if it is missing.

-@vertex
-fn vert_main(v_in: VertexInput) -> @builtin(position) vec4<f32> {...}
+@vertex
+fn vert_main(v_in: VertexInput) -> @builtin(position) @invariant vec4<f32> {...}

Surface Alpha and PresentModes

Surface supports alpha_mode now. When alpha_mode is equal to PreMultiplied or PostMultiplied, the alpha channel of framebuffer is respected in the compositing process, but which mode is available depends on the different API and Device. If don't care about alpha_mode, you can set it to Auto.

SurfaceConfiguration {
// ...
+ alpha_mode: surface.get_supported_alpha_modes(&adapter)[0],
}

The function to enumerate supported presentation modes changed:

- pub fn wgpu::Surface::get_supported_modes(&self, adapter: &wgpu::Adapter) -> Vec<PresentMode>
+ pub fn wgpu::Surface::get_supported_present_modes(&self, adapter: &wgpu::Adapter) -> Vec<PresentMode>

Updated raw-window-handle to 0.5

This will allow use of the latest version of winit. As such the bound on create_surface is now RWH 0.5 and requires both raw_window_handle::HasRawWindowHandle and raw_window_handle::HasRawDisplayHandle.

wgpu-0.13 (2022-06-30)

Major Changes

WGSL Syntax

WGSL syntax has changed in a couple ways. The new syntax is easier to read and work with.

Attribute declarations are written differently:

- [[group(1), binding(0)]]
+ @group(1) @binding(0)

Stage declarations are now separate attributes rather than part of the stage attribute:

- [[stage(vertex)]]
+ @vertex

Structs now use , as field separator and no longer need semicolons after the declaration:

- struct MyStruct {
-     my_member: u32;
- };
+ struct MyStruct {
+     my_member: u32,
+ }

Surface API

The method of getting the preferred swapchain format has changed to allow viewing all formats supported by the surface.

- let format = surface.get_preferred_format(&adapter).unwrap();
+ let format = surface.get_supported_formats(&adapter)[0];

Presentation modes now need to match exactly what the surface supports. FIFO is always supported, but all other modes vary from API to API and Device to Device. To get a list of all supported modes, call the following. The order does not indicate preference.

let modes = surface.get_supported_present_modes(&adapter);

Timestamp Queries

Timestamp queries are now restricted behind multiple features to allow implementation on TBDR (Tile-Based Deferred Rendering) based GPUs, such as mobile devices and Apple's M chips.

Features::TIMESTAMP_QUERIES now allows for calling write_timestamp only on CommandEncoders.

Features::WRITE_TIMESTAMP_INSIDE_PASSES is needed to call write_timestamp on RenderPassEncoders or ComputePassEncoders.

map_async

The function for mapping buffers no longer returns a future, and instead calls a callback when the buffer is mapped.

This aligns with the use of the API more clearly - you aren't supposed to block and wait on the future to resolve, you are supposed to keep rendering and wait until the buffer maps on its own. Mapping and the flow of mapping is an under-documented area that we hope to improve in the future.

- let future = buffer.slice(..).map_async(MapMode::Read);
+ buffer.slice(..).map_async(MapMode::Read, || {
+     // Called when buffer is mapped.
+ })

Submission Indexes

Calling queue.submit now returns an opaque submission index that can be used as an argument to device.poll to say which submission to wait to complete.

Other Breaking Changes

Device::create_shader_module now takes the shader descriptor by value:

- device.create_shader_module(&shader_module_descriptor)
+ device.create_shader_module(shader_module_descriptor)

Color attachments can be sparse, so they are now optional:

FragmentState {
-  targets: &[color_target_state]
+  targets: &[Some(color_target_state)]
  // ..
}

RenderPassDescriptor {
-  color_attachments: &[render_pass_color_attachment]
+  color_attachments: &[Some(render_pass_color_attachment)]
  // ..
}

RenderBundleEncoderDescriptor {
-  color_formats: &[texture_format]
+  color_formats: &[Some(texture_format)]
  // ..
}

Extent3d::max_mips now requires you to pass a TextureDimension to specify whether or not depth_or_array_layers should be ignored:

Extent3d {
  width: 1920,
  height: 1080,
  depth_or_array_layers: 6,
- }.max_mips()
+ }.max_mips(wgpu::TextureDimension::D3)

Limits has a new field, max_buffer_size (not an issue if you don't define limits manually):

Limits {
  // ...
+ max_buffer_size: 256 * 1024 * 1024, // adjust as you see fit
}

Features::CLEAR_COMMANDS is now unnecessary and no longer exists. The feature to clear buffers and textures is now part of upstream WebGPU.

DeviceDescriptor {
  // ...
  features: wgpu::Features::VERTEX_WRITABLE_STORAGE
    | wgpu::Features::MAPPABLE_PRIMARY_BUFFERS
    | wgpu::Features::TEXTURE_BINDING_ARRAY
    | wgpu::Features::BUFFER_BINDING_ARRAY
    | wgpu::Features::STORAGE_RESOURCE_BINDING_ARRAY
-    | wgpu::Features::CLEAR_COMMANDS
  ,
}

ComputePass::dispatch has been renamed to ComputePass::dispatch_workgroups

- cpass.dispatch(self.work_group_count, 1, 1)
+ cpass.dispatch_workgroups(self.work_group_count, 1, 1)
