Details
We have two issues with webgpu:api,operation,memory_sync,buffer,{single_buffer,multiple_buffers}:rw:*
tests right now:
TIMEOUT
s (patched in bug 1814088)FAIL
s, withUnexpected validation error occurred: Bind group layout is invalid
Steps to reproduce
- With a clean Firefox build based on patches from bug 1814088 or later, run one of the following test commands:
-
./mach wpt /_mozilla/webgpu/chunked/3/cts.https.html?q=webgpu:api,operation,memory_sync,buffer,multiple_buffers:rw:*
-
./mach wpt /_mozilla/webgpu/chunked/4/cts.https.html?q=webgpu:api,operation,memory_sync,buffer,single_buffer:rw:*
Observe that many tests fail. When run in CI, runs of these tests exceed their current time budget, resulting in TIMEOUT
s.
It is possible that this may be resolved or, in the case of resolving TIMEOUT
s, actually made feasible by changes to the structure of test chunks proposed in bug 1822630.

:ErichDonGubler, if you think that's a regression, could you try to find a regression range using for example mozregression?
