From 08d1c895359c89ff16e85bc86dbe66fe47c90274 Mon Sep 17 00:00:00 2001 From: "v.v.mitrofanov" Date: Mon, 31 Jan 2022 13:09:57 +0300 Subject: [PATCH 1/2] Get CPU MHz on RISC-V This test needs to know current CPU MHz value to output test results correctly. This patch set a CPU MHz value in case of using RISC-V arch. get_cpu_mhz() tries to acquire CPU MHz value from /proc/cpuinfo for some arches. It is not possible to get CPU MHz value from /proc/cpuinfo on RISC-V. It returns always 0. But it is possible to get this value calculated on cpu cycles. Use CPU cycles value calculated in sample_get_cpu_mhz(); This patch is tested on SiFive HiFive Unmatched board.
