Subject: [dpdk-dev] [PATCH v5 5/8] examples/ioat: add signal-triggered device dumps
Date: Tue, 26 Oct 2021 13:14:29 +0000 [thread overview]
Message-ID: <20211026131432.2734145-6-kevin.laatz@intel.com> (raw)
In-Reply-To: <20211026131432.2734145-1-kevin.laatz@intel.com>
Enable dumping device info via the signal handler. With this change, when a
SIGUSR1 is issued, the application will print a dump of all devices being
used by the application.
