| # Help: Debugging for CI systems and finding regressions |
| # |
| # The config is based on running daily CI for enterprise Linux distros to |
| # seek regressions on linux-next builds on different bare-metal and virtual |
| # platforms. It can be used for example, |
| # |
| # $ make ARCH=arm64 defconfig debug.config |
| # |
| # Keep alphabetically sorted inside each section. |
| # |
| # printk and dmesg options |
