v28 End-of-Cycle Call for Testing

[cwfitzgerald]

Trying something new here:

To make sure that we are aware of issues on many different pieces of hardware, I want to ask for people's help in running our test suite on their machine and posting the results here.

Setup:

1. clone/checkout wgpu's trunk branch
2. cargo +stable install cargo-nextest (binstall also works).
3. Important on Windows/Linux: Install the Vulkan SDK. This will cause failures on vulkan if this isn't present. Make sure the bin directory is in your PATH, and the VULKAN_SDK env var is set. Mac will experience a single failure of convert_snapshots_spv if this isn't done.

Running on Powershell:

cargo run --bin wgpu-info -v | Tee-Object -FilePath wgpu-info.txt
cargo xtask test 2>&1 | Tee-Object -FilePath tests.txt

Running on Bash:

cargo run --bin wgpu-info -v | tee wgpu-info.txt
cargo xtask test 2>&1 | tee tests.txt

Post the following:

• OS/Version
• git rev-parse HEAD
• Upload tests.txt and wgpu-info.txt as attachments.
• Any other information that might be useful.

Common Problems

rust-lld: error: could not open 'atls.lib': no such file or directory

• Open Visual Studio Installer
• Modify Installation
• Generic: Make sure "Desktop Developement for C++" is clicked
• Specific: Make sure "C++ ATL for latest build tools" in the category of desktop development is clicked.
• Hit "modify"

One test failure: naga::naga snapshots::convert_snapshots_spv

[cwfitzgerald]

@ChristopherBiscardi Thanks! That's because installing the vulkan SDK actually isn't optional on mac, and I completely forgot! No need to re-test though, thanks!

EDIT:

after installing the vulkan sdk with brew install vulkan-tools I now get one new test failure:

• Water will be fixed by Fix synchronization validation error in water example on Vulkan  #5231
• BCn is a bizzare end result from a long standing unimplemented thing in the GL backend, but couldn't find an issue, so filed [gl] Implement Copy Texture to Buffer for Compressed Texures #8614
• ray-cube-normals is ray_cube_normals Doesn't Fail on RADV #8615 where RADV doesn't fail where windows prop does.

• 1310 tests run: 1097 passed (1 slow), 213 failed, 18 skipped
  • test count is consistent between test runs, so I assume all device losts are real
  • may have forgotten to install the vulkan SDK, but most failures are from GL and VK mesh shader extensions

MAINTAINERS UPDATE:

• The GL problem is Indirect validation fails to init on some GL platforms. #8616
• The lavapipe issue thrown in there is wgpu_gpu::binding_array::samplers::binding_array_* fails on some lavapipe due to rounding #8617
• Other vulkan issues cause by glslc from the VulkanSDK not being in PATH
