Re: [PATCH] tests/igt: dmesg noise is a kernel failure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Double checking the full picture of the impact: 
- Current - test result value list for igt (=default piglit): pass, warn, dmesg-warn, fail, dmesg-fail, timeout, crash, incomplete
- Intent with proposal below - test result value list for igt (kernel testing): pass, warn, fail, dmesg-fail, timeout, crash, incomplete
Right or wrong?
Or will fail vanish from this list too like Chris said? Or will there be scenario where one can have fail without dmesg?

This is changing a fail to dmesg-fail. I hate that.
