Subject: [dpdk-dev] [PATCH v2 42/44] event/octeontx2: add devargs to limit timer adapters
Date: Fri, 28 Jun 2019 13:20:21 +0530 [thread overview]
Message-ID: <20190628075024.404-43-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20190628075024.404-1-pbhagavatula@marvell.com>
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Add devargs to limit the max number of TIM rings reserved on probe.
Since, TIM rings are HW resources we can avoid starving other
applications by not grabbing all the rings.
Example:
--dev "0002:0e:00.0,tim_rings_lmt=2"
