From: Adam Dybkowski Date: Tue, 6 Aug 2019 10:37:38 +0000 (+0200) Subject: app/compress-perf: fix floating point exception X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2097255731d5d3724063e9acf18b23bcbe4b7bac;p=dpdk.git app/compress-perf: fix floating point exception This patch fixes the floating point exception that happened when the number of cores to be used during the benchmark was zero. After the fix such situation is detected, the error message is printed and the benchmark application exits.
