Subject: [dpdk-dev] [PATCH] net/e1000 igb: fix compile issue with log register
Date: Mon, 21 May 2018 10:31:41 +0100 [thread overview]
Message-ID: <1526895101-146792-1-git-send-email-harry.van.haaren@intel.com> (raw)
This commit fixes a compilation error if EM_PMD is
not defined, bug IGB_PMD is. The root cause of the
issue was that log init variables are declared as
extern in a header file, while the definition of the
variables was in e1000_ethdev.c. Hence, the definitions
were not available if the e1000 PMD is disabled.
To fix this, a new file is added e1000_logs.c, which
matches the e1000_logs.h header. The log variables are
always compiled in, but the PMD logs are only registered
if a PMD is enabled in the configuration. Extra checks
are added in order to avoid duplicate registering.
Fixes: ed5bbb767c3e ("net/e1000: implement dynamic logging")
