Day-to-day Testing of Linux 'Next' Kernel Branch - My Story

on YouTube ↗39m

" summary

Daily automation runs kernel images from linux-next, boots them on a ~30 single-board computers test farm controlled over UART with power switches via USB CDC GPIO, captures logs and stack traces, and runs an expect-driven test script that returns pass/fail codes. Regression hunting uses git bisect + scripted tests plus stash/revert tricks to isolate multiple regressions; reports include hardware, config, reproducer and oops. Results: since v4.15 roughly 250 Tested-by / 90 Reported-by tags and over 100 reported commits in 5.19.
