Subject: [dpdk-dev] [PATCH v3] test: add delay time in test alarm
Date: Tue, 20 Jun 2017 11:24:11 +0800 [thread overview]
Message-ID: <1497929051-48912-1-git-send-email-qiming.yang@intel.com> (raw)
In-Reply-To: <1493950673-15953-1-git-send-email-qiming.yang@intel.com>
Because accuracy of timing to the microsecond is not guaranteed
in rte_eal_alarm_set, this function will not be called before
the requested time, but may be called a period of time
afterwards which can not be calculated. In order to ensure
test alarm running success, this patch added the delay time
before check the flag.
