Subject: [dpdk-dev] [PATCH v3 1/7] l3fwd-power: disable interrupts by default
Date: Fri, 19 Jun 2020 11:53:49 +0100 [thread overview]
Message-ID: <c72faa8937f99b6c3edc94caefbf219f19fb6c14.1592563994.git.anatoly.burakov@intel.com> (raw)
In-Reply-To: <cover.1592563994.git.anatoly.burakov@intel.com>
In-Reply-To: <cover.1592563994.git.anatoly.burakov@intel.com>
Currently, interrupts are enabled in telemetry and empty poll modes, but
they are not used. Switch to disabling interrupts by default, and only
enable interrupts for modes that require them.
