Yao Zi says: ==================== Add DWMAC glue driver for Motorcomm YT6801 This series adds glue driver for Motorcomm YT6801 PCIe ethernet controller, which is considered mostly compatible with DWMAC-4 IP by inspecting the register layout[1]. It integrates a Motorcomm YT8531S PHY (confirmed by reading PHY ID) and GMII is used to connect the PHY to MAC[2]. The initialization logic of the MAC is mostly based on previous upstream effort for the controller[3] and the Deepin-maintained downstream Linux driver[4] licensed under GPL-2.0 according to its SPDX headers. However, this series is a completely re-write of the previous patch series, utilizing the existing DWMAC4 driver and introducing a glue driver only. This series only aims to add basic networking functions for the controller, features like WoL, RSS and LED control are omitted for now. Testing is done on i3-4170, it reaches 939Mbps (TX)/933Mbps (RX) on average, YT6801 TX Connecting to host 192.168.114.51, port 5201 [ 5] local 192.168.114.50 port 52986 connected to 192.168.114.51 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 112 MBytes 938 Mbits/sec 0 950 KBytes [ 5] 1.00-2.00 sec 113 MBytes 949 Mbits/sec 0 1.08 MBytes [ 5] 2.00-3.00 sec 112 MBytes 938 Mbits/sec 0 1.08 MBytes [ 5] 3.00-4.00 sec 111 MBytes 932 Mbits/sec 0 1.13 MBytes [ 5] 4.00-5.00 sec 113 MBytes 945 Mbits/sec 0 1.13 MBytes [ 5] 5.00-6.00 sec 112 MBytes 936 Mbits/sec 0 1.13 MBytes [ 5] 6.00-7.00 sec 112 MBytes 942 Mbits/sec 0 1.19 MBytes [ 5] 7.00-8.00 sec 112 MBytes 935 Mbits/sec 0 1.19 MBytes [ 5] 8.00-9.00 sec 113 MBytes 948 Mbits/sec 0 1.19 MBytes [ 5] 9.00-10.00 sec 111 MBytes 931 Mbits/sec 0 1.19 MBytes YT6801 RX Connecting to host 192.168.114.50, port 5201 [ 5] local 192.168.114.51 port 41578 connected to 192.168.114.50 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 113 MBytes 944 Mbits/sec 0 542 KBytes [ 5] 1.00-2.00 sec 111 MBytes 934 Mbits/sec 0 850 KBytes [ 5] 2.00-3.00 sec 111 MBytes 933 Mbits/sec 0 1.01 MBytes [ 5] 3.00-4.00 sec 112 MBytes 943 Mbits/sec 0 1.01 MBytes [ 5] 4.00-5.00 sec 111 MBytes 932 Mbits/sec 0 1.01 MBytes [ 5] 5.00-6.00 sec 111 MBytes 929 Mbits/sec 0 1.01 MBytes [ 5] 6.00-7.00 sec 112 MBytes 937 Mbits/sec 0 1.01 MBytes [ 5] 7.00-8.00 sec 112 MBytes 941 Mbits/sec 0 1.01 MBytes [ 5] 8.00-9.00 sec 111 MBytes 929 Mbits/sec 0 1.01 MBytes [ 5] 9.00-10.00 sec 111 MBytes 932 Mbits/sec 0 1.01 MBytes ==================== Link: https://patch.msgid.link/20260109093445.46791-2-me@ziyao.cc Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
