Use POSIX jobserver when available or -j<number> to run PDF builds in parallel, restoring pdf build performance. Yet, running it when debugging troubles is a bad idea, so, when calling directly via command line, except if "-j" is splicitly requested, it will serialize the build. With such change, a PDF doc builds now takes around 5 minutes on a Ryzen 9 machine with 32 cpu threads: # Explicitly paralelize both Sphinx and LaTeX pdf builds $ make cleandocs; time scripts/sphinx-build-wrapper pdfdocs -j 33 real 5m17.901s user 15m1.499s sys 2m31.482s # Use POSIX jobserver to paralelize both sphinx-build and LaTeX $ make cleandocs; time make pdfdocs real 5m22.369s user 15m9.076s sys 2m31.419s # Serializes PDF build, while keeping Sphinx parallelized. # it is equivalent of passing -jauto via command line $ make cleandocs; time scripts/sphinx-build-wrapper pdfdocs real 11m20.901s user 13m2.910s sys 1m44.553s Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Message-ID: <42eef319f9af6f9feb12bcd74ca6392c8119929d.1758196090.git.mchehab+huawei@kernel.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net> |
