XO-4/Kernel/Runin

From OLPC

Checklist for customising runin for kernel testing. See also Olpc-runin-tests.

[edit] disarm fscheck

This disarms the filesystem consistency check, but doesn't stop it running. The log will contain reports of failure that don't stop the whole run.

touch /runin/soiled

It is necessary if any files outside /home/olpc have been removed or changed, such as kernel or runin tests. It is not necessary if files have been created that were not previously present, such as runin flags.

[edit] set aggressive suspend timings

This sets ten second awake, ten second suspend timings.

touch /runin/aggressive

This is done so as to stress suspend and resume.

[edit] set extreme suspend timings

This sets zero seconds awake, three seconds suspend timings.

touch /runin/extreme

This is done so as to stress suspend and resume.

[edit] ignore repeated hangs

By default, runin reports a fail if the number of hangs exceeds three. To turn off the repeated hang detection fail:

touch /runin/no-fail-hangs

[edit] optional, disable individual tests

Individual tests can be disabled by creating a corresponding no- file.

touch /runin/no-battery

runin-gtk is required to be present, unless runin-tests is edited to remove all reference to it.

[edit] optional, exclude wireless card

This excludes the wireless card and driver:

touch /runin/no-{wireless,bluetooth}
echo blacklist btmrvl_sdio > /etc/modprobe.d/olpc.conf
echo blacklist mwifiex_sdio >> /etc/modprobe.d/olpc.conf

This is done so as to exclude known problems with the card and driver.

[edit] optional, logging verbosity

• run olpc-dev-kernel at least once,
• edit olpc.fth and add no_console_suspend to the kernel command line,
• for more verbosity, add debug and/or initcall_debug to the kernel command line
• log the output of the serial console.

This is done to increase the amount of information available for diagnosis.
