H A D | qlnx_os.h | diff 318657 Mon May 22 19:26:07 MDT 2017 davidcs MFC r318382 1. Move Rx Processing to fp_taskqueue(). With this CPU utilization for processing interrupts drops to around 1% for 100G and under 1% for other speeds. 2. Use sysctls for TRACE_LRO_CNT and TRACE_TSO_PKT_LEN 3. remove unused mtx tx_lock 4. bind taskqueue kernel thread to the appropriate cpu core 5. when tx_ring is full, stop further transmits till at least 1/16th of the Tx Ring is empty. In our case 1K entries. Also if there are rx_pkts to process, put the taskqueue thread to sleep for 100ms, before enabling interrupts. 6. Use rx_pkt_threshold of 128. |
