From e4f27af0f448cdf97fa320a9f429734a387e4543 Mon Sep 17 00:00:00 2001 From: Jerin Jacob Date: Mon, 4 May 2020 18:56:53 +0530 Subject: [PATCH] bus/pci: reduce boot-up logs to absolute minimum 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.
