Summary

This allows us to build kernels which will (if the sysctl is enabled
too) to show pr_debug() and pr_devel() output.

Enable it by default for debug kernels.

This option can later also be used for other LinuxKPI parts, like
skbuffs, netdevice, rcu, ... to conditionally compile in debugging
support to further justify its existence beyond an in-code #define.

opt-Linuxkpi.h should likely also just be added to LINUXKPI_GENSRCS?

bz updated this revision to Diff 168754.Dec 30 2025, 12:26 AM

Also add opt_linuxkpi.h to LINUXKPI_GENSRCS by default.

sys/conf/std.nodebug is missing

bz updated this revision to Diff 178531.May 24 2026, 11:24 PM

Add the missing std.nnodebug line.

If this is OK now and could go in then I could make more use of it.
