Description Gabriel Linder 2021-09-20 07:33:28 UTC 
Was looking for a kernel regression on my laptop (likely caused by https://bugzilla.kernel.org/show_bug.cgi?id=214455) and so was looking for C files in /usr/src/linux-5.14.6-gentoo-dist, but the only ones availables are in tools and scripts folders, no other kernel code found.

Exemple for the driver I was looking for :

$ ls -al /usr/src/linux-5.14.6-gentoo-dist/net/qrtr/
total 12K
drwxr-xr-x  2 root root   37 Sep 19 23:03 .
drwxr-xr-x 71 root root 4096 Sep 19 23:03 ..
-rw-r--r--  1 root root 1082 Aug 30 00:04 Kconfig
-rw-r--r--  1 root root  246 Aug 30 00:04 Makefile

Yep, that's all.

Reproducible: Always

The build log from linux-5.14.6-gentoo-dist would be useful if you could rebuild it.

That's by design.  Installing sources for an already-built kernel wastes a lot of space.  If you want sources, use gentoo-sources.

(or just use ebuild(1) to play with the ebuild, and work on the build tree directly)

Ugh, duh. Too tired.

I see, I should have read the eclass. Thanks for explanations.
