Subject: [dpdk-stable] [PATCH v3 3/3] test/power: sleep 1s before check cpuinfo_cur_freq
Date: Wed,  7 Apr 2021 14:38:22 +0800
Message-ID: <> (raw)
In-Reply-To: <>

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")
