While consolidating this, it also became obvious that some drivers behave differently for no good reason. It also was a good chance to introduce atomic exchange primitives in EAL because there are other places using cmpset where not necessary (such as bonding). Mostly only compile tested only, don't have all of the hardware available (except ixgbe and virtio) to test. Note: the eth_dev_link_update function return value is inconsistent across drivers. Should be changed to be void. v5 - checkpatch whitespace cleanup v4 - incorporate review feedback - rename _rte_linkstatus to rte_linkstatus - change return value of _rte_linkstatus - optimize get on 64bit platforms - change return value of rte_linkstatus_set v3 - align rte_linkstatus_get with rte_atomic64_read - virtio use ETH_SPEED_NUM_10G - add net/ v2 - function names changed - rebased to current master Stephen Hemminger (15): eal: introduce atomic exchange operation ethdev: add linkstatus get/set helper functions net/virtio: use eth_linkstatus_set net/vmxnet3: use rte_eth_linkstatus_set net/dpaa2: use rte_eth_linkstatus_set net/nfp: use rte_eth_linkstatus functions net/e1000: use rte_eth_linkstatus helpers net/ixgbe: use rte_eth_linkstatus functions net/sfc: use new rte_eth_linkstatus functions net/i40e: use rte_eth_linkstatus functions net/liquidio: use rte_eth_linkstatus_set net/thunderx: use rte_eth_linkstatus_set net/szedata: use _rte_eth_linkstatus_set net/octeontx: use rte_eth_linkstatus_set net/enic: use rte_eth_linkstatus_set drivers/net/dpaa2/dpaa2_ethdev.c | 75 ++--------------- drivers/net/e1000/em_ethdev.c | 69 ++-------------- drivers/net/e1000/igb_ethdev.c | 70 ++-------------- drivers/net/enic/enic_ethdev.c | 5 +- drivers/net/enic/enic_main.c | 17 ++-- drivers/net/i40e/i40e_ethdev.c | 43 ++-------- drivers/net/i40e/i40e_ethdev_vf.c | 18 +--- drivers/net/ixgbe/ixgbe_ethdev.c | 96 ++++------------------ drivers/net/liquidio/lio_ethdev.c | 53 ++---------- drivers/net/nfp/nfp_net.c | 77 ++--------------- drivers/net/octeontx/octeontx_ethdev.c | 17 +--- drivers/net/sfc/sfc_ethdev.c | 21 +---- drivers/net/sfc/sfc_ev.c | 20 +---- drivers/net/szedata2/rte_eth_szedata2.c | 19 ++--- drivers/net/thunderx/nicvf_ethdev.c | 18 +--- drivers/net/virtio/virtio_ethdev.c | 65 +++------------ drivers/net/vmxnet3/vmxnet3_ethdev.c | 86 ++++--------------- .../common/include/arch/x86/rte_atomic.h | 24 ++++++ .../common/include/arch/x86/rte_atomic_32.h | 12 +++ .../common/include/arch/x86/rte_atomic_64.h | 12 +++ lib/librte_eal/common/include/generic/rte_atomic.h | 78 ++++++++++++++++++ lib/librte_ether/rte_ethdev.c | 22 +---- lib/librte_ether/rte_ethdev.h | 62 ++++++++++++++ 23 files changed, 302 insertions(+), 677 deletions(-) -- 2.15.1
