Subject: [PATCH] improve caching of kernel overlays
Date: Tue, 2 Aug 2022 09:21:48 +0200 [thread overview]
Message-ID: <20220802072148.1145167-1-felix.moessbauer@siemens.com> (raw)
The kernel build supports KERNEL_OVERLAYS to overlay the official kernel
sources with custom ones.
These overlays are referenced using absolute paths, which leads to
absolute include directories on the compiler cmdline.
As the sbuilder injects some randomness into the build path,
this breaks ccache caching.
To fix this, we set the CCACHE_BASEDIR to the CURDIR
for the kernel build.
