These two patches should speed up the make deb-pkg build process by utilizing the make jobserver properly, and using 'find | xargs' to parallelize debug module installation. I've tested with the resulting packages to ensure the symbols work as intended by crash dumping a machine and using the dbg package symbols. Using an Ubuntu distro conf + make olddefconfig on a 56-core machine, I can see the following improvements (make clean && make deb-pkg -j`nproc`): * Before real 40m56.240s user 182m17.292s sys 140m18.812s * After real 36m22.633s user 182m28.028s sys 148m17.724s Original submission: https://lkml.org/lkml/2015/4/24/617 Chris J Arges (2): package: Makefile: ensure $MAKE can use jobserver builddeb: parallelize debug module installation scripts/package/Makefile | 2 +- scripts/package/builddeb | 19 ++++++++++++------- 2 files changed, 13 insertions(+), 8 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
