Subject: [PATCH] kbuild: modinst: remove the multithread option from zstd compression
Date: Sun, 4 Aug 2024 12:33:07 +0900 [thread overview]
Message-ID: <20240804033309.890181-1-masahiroy@kernel.org> (raw)
Parallel execution is supported by GNU Make:
$ make -j<N> modules_install
It is questionable to enable multithreading within each zstd process
by default.
If you still want to do it, you can use the environment variable:
$ ZSTD_NBTHREADS=<N> make modules_install
