Pad small packets to ETH_ZLEN before transmit, cleanup dma sync calls, add xmit_more functionality and then further remove atomic variable usage in the prior. Changes: V3: - Stop returning NETDEV_TX_BUSY when ring is full in xmit_patch. Change to inspect early if next packet can fit in ring instead of current packet, and stop queue if not. - Add smp_mb between stopping tx queue and checking if tx queue has free entries again, in queue full check function to let reflect IQ process completions that might have happened on other cpus. - Update small packet padding patch changelog to give more info. V2: https://lore.kernel.org/all/20231024145119.2366588-1-srasheed@marvell.com/ - Added patch for padding small packets to ETH_ZLEN, part of optimization patches for transmit code missed out in V1 - Updated changelog to provide more details for dma_sync remove patch - Updated changelog to use imperative tone in add xmit_more patch V1: https://lore.kernel.org/all/20231023114449.2362147-1-srasheed@marvell.com/ Shinas Rasheed (4): octeon_ep: add padding for small packets octeon_ep: remove dma sync in trasmit path octeon_ep: implement xmit_more in transmit octeon_ep: remove atomic variable usage in Tx data path .../ethernet/marvell/octeon_ep/octep_config.h | 3 +- .../ethernet/marvell/octeon_ep/octep_main.c | 55 +++++++++++-------- .../ethernet/marvell/octeon_ep/octep_main.h | 9 +++ .../net/ethernet/marvell/octeon_ep/octep_tx.c | 5 +- .../net/ethernet/marvell/octeon_ep/octep_tx.h | 3 - 5 files changed, 45 insertions(+), 30 deletions(-)
