From 7b1642f2fc1e1f20948e806b7ce319f660633342 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 30 Mar 2020 09:32:41 -0300 Subject: [PATCH] perf build-test: Honour JOBS to override detection of number of cores When one does: $ make -C tools/perf build-test The makefile in tools/perf/tests/ will, just like the main one, detect how many cores are in the system and use it with -j. Sometimes we may need to override that, for instance, when using icecream or distcc to use multiple machines in the build process, then we need to, as with the main makefile, use: $ make JOBS=N -C tools/perf build-test Fix the tests makefile to honour that.
