Avoid code which generates branching when calculating min and max. Ravi Kerur (1): Fix rte_is_power_of_2() function since it returns true for zero and zero is not a power of 2. Avoid branching in RTE_MIN and RTE_MAX when calculating minimum and maximum of two numbers. lib/librte_eal/common/include/rte_common.h | 6 +++--- lib/librte_pmd_e1000/igb_pf.c | 4 ++-- lib/librte_pmd_ixgbe/ixgbe_pf.c | 4 ++-- 3 files changed, 7 insertions(+), 7 deletions(-) -- 1.9.1 ^ permalink raw reply [flat|nested] only message in thread
