Linux Kernel Testing Results by Linaro Feb 7th Edition

Posted: February 7, 2019 in Uncategorized

This report is broken up into two parts, OpenEmbedded and Android. These are the two operating systems we are using to run a battery of tests in order to find regressions in the kernel as new patches are added.

The general list of tests that Linaro runs can be found at https://lkft.linaro.org/tests/

When we look for regressions tests often fall into 3 categories of results. Pass, Fail (a regression, exactly what we want to find) and Known Failure where there is a past history with the testcase. Often known failures are flaky testscases that need to be fixed.
