# Update the kernel command-line parameters

To update the kernel command line, modify `KERNEL_CMDLINE_EXTRA` in
`meta-qcom/ci/base.yml` to apply the change across all machines, or in the
SoC-specific machine inclusion file
(`meta-qcom/conf/machine/include/qcom-<SoC>.inc`) to apply it to a single target:

```text theme={null}
KERNEL_CMDLINE_EXTRA:append = "console=ttyMSM0,115200n8 earlycon"
```
