Hi,
I have an amdgpu based laptop (zephyrus G14 2022) and I noticed that the hardware acceleration is not used when I watch video on youtube. I started to dig on the subject but I am facing a wall. Basically the browser reports that the hardware acceleration is active but if I take a look to the media tab in developer tools I see that the software renderer is used.
My setup is:
- NixOS (unstable channel)
- Vivaldi 5.6, Google Chrome stable 109, Chromium 109
- AMD iGPU Rembrandt [Radeon 680M]
- Wayland (Sway) with NIXOS_OZONE_WL env variable set
In my flake I have the following configuration:
hardware = {
opengl = {
enable = true;
driSupport = true;
driSupport32Bit = true;
extraPackages = with pkgs; [
amdvlk
];
};
};
When I start chromium with the command chromium --enable-features=VaapiVideoDecoder and check the acceleration status in chrome://gpu I can see this:
Graphics Feature Status
Canvas: Hardware accelerated
Canvas out-of-process rasterization: Disabled
Direct Rendering Display Compositor: Disabled
Compositing: Hardware accelerated
Multiple Raster Threads: Enabled
OpenGL: Enabled
Rasterization: Hardware accelerated
Raw Draw: Disabled

DAWN Info
<CPU> Vulkan backend - SwiftShader Device (Subzero)
[Default Toggle Names]
lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource.
use_temporary_buffer_in_texture_to_texture_copy: https://crbug.com/dawn/42: Split texture-to-texture copy into two copies: copy from source texture into a temporary buffer, and copy from the temporary buffer into the destination texture when copying between compressed textures that don't have block-aligned sizes. This workaround is enabled by default on all Vulkan drivers to solve an issue in the Vulkan SPEC about the texture-to-texture copies with compressed formats. See #1005 (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more details.
vulkan_use_d32s8: https://crbug.com/dawn/286: Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When available the backend will use D32S8 (toggle to on) but setting the toggle to off will make it use the D24S8 format when possible.
vulkan_use_s8: https://crbug.com/dawn/666: Vulkan has a pure stencil8 format but it is not universally available. When this toggle is on, the backend will use S8 for the stencil8 format, otherwise it will fallback to D32S8 or D24S8.
disallow_unsafe_apis: http://crbug.com/1138528: Produces validation errors on API entry points or parameter combinations that aren't considered secure yet.
use_vulkan_zero_initialize_workgroup_memory_extension: https://crbug.com/dawn/1302: Initialize workgroup memory with OpConstantNull on Vulkan when the Vulkan extension VK_KHR_zero_initialize_workgroup_memory is supported.
[WebGPU Forced Toggles - enabled]
disallow_spirv: https://crbug.com/1214923: Disallow usage of SPIR-V completely so that only WGSL is used for shader modules. This is useful to prevent a Chromium renderer process from successfully sending SPIR-V code to be compiled in the GPU process.
