This patch fixes the StarFive JH7110 gmac TCP RX slow issue. And it has been tested on VisionFive 2. Here is the result of the test (iperf3): Before: # iperf3 -s ----------------------------------------------------------- Server listening on 5201 (test #1) ----------------------------------------------------------- Accepted connection from 192.168.1.4, port 47604 [ 5] local 192.168.1.3 port 5201 connected to 192.168.1.4 port 47612 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 36.3 MBytes 305 Mbits/sec [ 5] 1.00-2.00 sec 35.6 MBytes 299 Mbits/sec [ 5] 2.00-3.00 sec 36.5 MBytes 306 Mbits/sec [ 5] 3.00-4.00 sec 36.5 MBytes 306 Mbits/sec [ 5] 4.00-5.00 sec 35.7 MBytes 300 Mbits/sec [ 5] 5.00-6.00 sec 35.4 MBytes 297 Mbits/sec [ 5] 6.00-7.00 sec 37.1 MBytes 311 Mbits/sec [ 5] 7.00-8.00 sec 35.6 MBytes 298 Mbits/sec [ 5] 8.00-9.00 sec 36.4 MBytes 305 Mbits/sec [ 5] 9.00-10.00 sec 36.3 MBytes 304 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate [ 5] 0.00-10.00 sec 361 MBytes 303 Mbits/sec receiver After: # iperf3 -s ----------------------------------------------------------- Server listening on 5201 (test #1) ----------------------------------------------------------- Accepted connection from 192.168.1.4, port 47710 [ 5] local 192.168.1.3 port 5201 connected to 192.168.1.4 port 47720 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 111 MBytes 932 Mbits/sec [ 5] 1.00-2.00 sec 111 MBytes 934 Mbits/sec [ 5] 2.00-3.00 sec 111 MBytes 934 Mbits/sec [ 5] 3.00-4.00 sec 111 MBytes 934 Mbits/sec [ 5] 4.00-5.00 sec 111 MBytes 934 Mbits/sec [ 5] 5.00-6.00 sec 111 MBytes 935 Mbits/sec [ 5] 6.00-7.00 sec 111 MBytes 934 Mbits/sec [ 5] 7.00-8.00 sec 111 MBytes 935 Mbits/sec [ 5] 8.00-9.00 sec 111 MBytes 934 Mbits/sec [ 5] 9.00-10.00 sec 111 MBytes 934 Mbits/sec [ 5] 10.00-10.00 sec 167 KBytes 933 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate [ 5] 0.00-10.00 sec 1.09 GBytes 934 Mbits/sec receiver For more information and support, you can visit RVspace wiki[1].
