Subject: [dpdk-dev] [PATCH v2] bus/pci: set boot-up log prints to absolute minimum
Date: Mon, 4 May 2020 18:56:53 +0530
Message-ID: <20200504132653.3668706-1-jerinj@marvell.com> (raw)
In-Reply-To: <20200121080021.2835490-1-jerinj@marvell.com>

From: Jerin Jacob <jerinj@marvell.com>

Some machines may have a lot of PCI devices and all of them are
not bound to DPDK. In such case the logs from EAL creates a lot of
clutter on boot-up, typically one needs to scroll the screen to
find other issues in boot-up.

This patch changes the following to reduce the clutter in
the default boot-up logs.

- Change the log-level of PCI probes to `debug`
- Introduce new driver probe as `info` log-level for the successful probe.

Signed-off-by: Jerin Jacob <jerinj@marvell.com>

v2:
- Introduce new driver probe as `info` log-level for the successful
  probe(Thomas)
