From: Gowrishankar Muthukrishnan Date: Tue, 30 Jan 2018 08:59:13 +0000 (+0530) Subject: eal/ppc64: revert arch-specific TSC freq query X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4e4b97b71ca0f25b2b7ceb03d21a100f74fa4512;p=dpdk.git eal/ppc64: revert arch-specific TSC freq query This reverts commit 15692396fd68932b6a81f00f12d4b0da12baa7d3 (eal/ppc64: implement arch-specific TSC freq query). We intended to derive pkt/sec estimation with cpu clock frequency. As timebase register serves the timer purpose, we need to stick with it for calculating pkt/sec, hence reverting the change.
