Subject: [dpdk-dev] [PATCH v3 3/3] test/power: add delay before checking cpuinfo cur freq
Date: Wed,  7 Apr 2021 15:46:36 +0800
Message-ID: <20210407074636.26891-4-richael.zhuang@arm.com> (raw)
In-Reply-To: <20210407074636.26891-1-richael.zhuang@arm.com>

Sleep for 1s before checking the newly updated value from
"/sys/devices/system/cpu/cpu%u/cpufreq/cpuinfo_cur_freq", because
for some systems it may not be effective immediately.

Fixes: ed7c51a6a680 ("app/test: vm power management")
