Subject: [dpdk-dev] [PATCH v2 2/3] drivers: fix log level after loading
Date: Mon,  5 Apr 2021 12:03:00 +0200
Message-ID: <20210405100301.657768-3-thomas@monjalon.net> (raw)
In-Reply-To: <20210405100301.657768-1-thomas@monjalon.net>

When compiled as a shared object, and loaded at runtime as a plugin,
the drivers should get the log level set earlier at EAL init
by the user through --log-level option.

The function for applying the log level setting is
rte_log_register_type_and_pick_level().
It is called by most drivers via RTE_LOG_REGISTER().

The drivers common/mlx5, bcmfs and e1000 were missing,
so the user-specified log level was not applied when
those drivers were loaded as plugins.
The macro RTE_LOG_REGISTER() is used for those drivers.

The unnecessary protection for double registration
is removed from e1000.

Fixes: 9c99878aa1b1 ("log: introduce logtype register macro")
Fixes: c8e79da7c676 ("crypto/bcmfs: introduce BCMFS driver")
