Subject: [PATCH 4/6] perf tools: Set JOBS based on CPU or processor
Date: Thu, 26 Mar 2015 12:41:03 -0300	[thread overview]
Message-ID: <1427384465-7601-5-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1427384465-7601-1-git-send-email-acme@kernel.org>

From: David Ahern <david.ahern@oracle.com>

Number of JOBS to use is set automatically to the number of processors found
in /proc/cpuinfo. SPARC uses 'CPU' lines rather than 'processor'. Update the
check in perf's Makefile to work for SPARC.
