| |
Hi all,
Commit 6428c59a97de ("perf tools: Set JOBS based on CPU or processor") causes weird behaviour on arm/arm64 platforms because we use the "CPU" prefix for things like:
CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd03 CPU revision : 0
in /proc/cpuinfo. Consequently, a 6 core machine ends up doing:
will@confinement-loaf:~/linux/tools/perf$ make BUILD: Doing 'make -j36' parallel build
which is a little overwhelming. Any chance we can predicate the extra part of the regex on $(ARCH) being sparc?
Will
