In drivers/net/ixgbe/ixgbe_logs.h, there are
#ifdef RTE_LIBRTE_IXGBE_DEBUG_DRIVER
#define PMD_DRV_LOG_RAW(level, fmt, args...) \
RTE_LOG(level, PMD, "%s(): " fmt, __func__, ## args)
#else
#define PMD_DRV_LOG_RAW(level, fmt, args...) do { } while (0)
#endif
And in drivers/net/ixgbe/base/ixgbe_osdep.h, there are
#include "../ixgbe_logs.h"
....
#define DEBUGOUT(S, args...) PMD_DRV_LOG_RAW(DEBUG, S, ##args)
#define DEBUGOUT1(S, args...) DEBUGOUT(S, ##args)
#define DEBUGOUT2(S, args...) DEBUGOUT(S, ##args)
#define DEBUGOUT3(S, args...) DEBUGOUT(S, ##args)
#define DEBUGOUT6(S, args...) DEBUGOUT(S, ##args)
#define DEBUGOUT7(S, args...) DEBUGOUT(S, ##args)
In config/common_base, there is
CONFIG_RTE_LIBRTE_IXGBE_DEBUG_DRIVER=n
So according above codes, the macro RTE_LIBRTE_IXGBE_DEBUG_DRIVER in drivers/net/ixgbe/ixgbe_logs.h is not defined
and PMD_DRV_LOG_RAW(level, fmt, args...) do { } while (0) will be valid,
then DEBUGOUT() is just a null definition by default.
