From: Bruce Richardson Date: Fri, 28 Apr 2017 10:18:15 +0000 (+0100) Subject: examples/performance-thread: fix build on FreeBSD 10.0 X-Git-Tag: spdx-start~3311 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b7162fee8811461fb87dd9c5b843b3d1ba283e5c;p=dpdk.git examples/performance-thread: fix build on FreeBSD 10.0 While later releases in the FreeBSD 10 series have a CPU_COUNT macro defined, FreeBSD 10.0 and 10.1 do not have this macro. Therefore we provide a basic fallback implementation of the macro for platforms where it is not defined.
