Over the years we have been accumulating a number of patches improving support for the IEEE 802.11bgn 2T2R wireless interface built into the MediaTek MT7620 MIPS SoCs. Many of them have not been in shape for being submitted to Linux and changes were needed to make checkpatch.pl all happy (it is now). Now they look as good as it gets, given that most code deals with undocumented registers and was adapted from the vendor driver. Patch 01/16 also has been previously submitted and then (imho wrongly) rejected, so I've included it in this series with an updated commit message. Patch 02/16 also has been previously submitted but never received any feedback. I've also included it here again because having a more informative LED trigger is definitely an improvement. Alltogether rt2x00 now performs almost as good as the vendor driver, see benchmark of HT20 client below: Accepted connection from 192.168.5.133, port 37382 [ 5] local 192.168.5.175 port 5201 connected to 192.168.5.133 port 37384 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 9.57 MBytes 80.3 Mbits/sec [ 5] 1.00-2.00 sec 9.68 MBytes 81.2 Mbits/sec [ 5] 2.00-3.00 sec 9.98 MBytes 83.7 Mbits/sec [ 5] 3.00-4.00 sec 9.72 MBytes 81.6 Mbits/sec [ 5] 4.00-5.00 sec 9.49 MBytes 79.6 Mbits/sec [ 5] 5.00-6.00 sec 9.88 MBytes 82.9 Mbits/sec [ 5] 6.00-7.00 sec 9.76 MBytes 81.8 Mbits/sec [ 5] 7.00-8.00 sec 9.96 MBytes 83.6 Mbits/sec [ 5] 8.00-9.00 sec 9.76 MBytes 81.9 Mbits/sec [ 5] 9.00-10.00 sec 9.86 MBytes 82.7 Mbits/sec [ 5] 10.00-10.03 sec 243 KBytes 78.4 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate [ 5] 0.00-10.03 sec 97.9 MBytes 81.9 Mbits/sec receiver Accepted connection from 192.168.5.133, port 49588 [ 5] local 192.168.5.175 port 5201 connected to 192.168.5.133 port 49598 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 12.7 MBytes 106 Mbits/sec 0 557 KBytes [ 5] 1.00-2.00 sec 11.1 MBytes 93.0 Mbits/sec 0 1020 KBytes [ 5] 2.00-3.00 sec 11.2 MBytes 94.4 Mbits/sec 0 1.57 MBytes [ 5] 3.00-4.00 sec 11.2 MBytes 94.4 Mbits/sec 0 1.58 MBytes [ 5] 4.00-5.00 sec 10.0 MBytes 83.9 Mbits/sec 0 1.58 MBytes [ 5] 5.00-6.00 sec 11.2 MBytes 94.4 Mbits/sec 0 1.58 MBytes [ 5] 6.00-7.00 sec 11.2 MBytes 94.4 Mbits/sec 0 1.58 MBytes [ 5] 7.00-8.00 sec 10.0 MBytes 83.9 Mbits/sec 0 1.58 MBytes [ 5] 8.00-9.00 sec 12.5 MBytes 105 Mbits/sec 0 1.58 MBytes [ 5] 9.00-10.00 sec 10.0 MBytes 83.9 Mbits/sec 0 1.58 MBytes [ 5] 10.00-10.03 sec 1.25 MBytes 381 Mbits/sec 0 1.58 MBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.03 sec 112 MBytes 94.1 Mbits/sec 0 sender v2: comments from Stanislaw Gruszka have been addressed. v3: don't export function only used inside rt2800lib.c Reported-by: kernel test robot <lkp@xxxxxxxxx> Daniel Golle (9): rt2x00: add support for external PA on MT7620 rt2x00: move up and reuse busy wait functions rt2x00: don't run Rt5592 IQ calibration on MT7620 rt2x00: move helper functions up in file rt2x00: fix HT20/HT40 bandwidth switch on MT7620 rt2x00: set correct TX_SW_CFG1 MAC register for MT7620 rt2x00: set VGC gain for both chains of MT7620 rt2x00: set SoC wmac clock register rt2x00: correctly set BBP register 86 for MT7620 David Bauer (1): rt2x00: add throughput LED trigger Tomislav Požega (6): rt2x00: define RF5592 in init_eeprom routine rt2x00: add RF self TXDC calibration for MT7620 rt2x00: add r calibration for MT7620 rt2x00: add RXDCOC calibration for MT7620 rt2x00: add RXIQ calibration for MT7620 rt2x00: add TX LOFT calibration for MT7620 drivers/net/wireless/ralink/rt2x00/rt2800.h | 3 + .../net/wireless/ralink/rt2x00/rt2800lib.c | 1753 ++++++++++++++++- .../net/wireless/ralink/rt2x00/rt2800lib.h | 10 + .../net/wireless/ralink/rt2x00/rt2x00dev.c | 18 + 4 files changed, 1706 insertions(+), 78 deletions(-) -- 2.37.3
