Subject: [dpdk-dev] [PATCH v3] app/eventdev: add option to set global dequeue tmo
Date: Fri, 29 Mar 2019 07:11:46 +0000 [thread overview]
Message-ID: <20190329071106.3448-1-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20190319061845.12343-1-pbhagavatula@marvell.com>
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Add option to provide a global dequeue timeout that is used to create
the eventdev.
The dequeue timeout provided will be common across all the worker
ports. If the eventdev hardware supports power management through
dequeue timeout then this option can be used for verifying power
demands at various packet rates.
Signed-off-by: Pavan Nikhilesh <pbhagavatula@marvell.com>
---
v3 Changes:
- Move common changes to evt_common.h.
v2 Changes:
- Update documentation and fix indentation.
- Add check to see if provided dequeue timeout is within range and adjust as
required
