Subject: [dpdk-dev] [PATCH] vhost: Add dynamic logging system
Date: Wed,  4 Dec 2019 16:07:29 +0100
Message-ID: <20191204150729.31816-1-amorenoz@redhat.com> (raw)

Currently there are a couple of limitations on the logging system: Most
of the logs are compiled out and both datapath and controlpath logs
share the same loglevel.

This patch tries to help fix that situation by:
- Splitting control plane and data plane logs
- Making control plane logs dynamic while keeping data plane logs
compiled out by default for log levels lower than the INFO.

As a result, two macros are introduced:
- VHOST_LOG_CONFIG(LEVEL, ...): Config path logging. Level can be
dynamically controlled by "lib.vhost.config"

- VHOST_LOG_DATA(LEVEL, ...): Data path logging. Level can be dynamically
controlled by "lib.vhost.data". Every log macro with a level lower than
RTE_LOG_DP_LEVEL (which defaults to RTE_LOG_INFO) will be compiled out.

Signed-off-by: Adrian Moreno <amorenoz@redhat.com>
Fixes: 1c01d52392d5 ("vhost: add debug print")
