For RX, it has two parts, one is to read data from sdio, another is to indicate the packets to upper stack. Recently it has only one thread to do all RX things, it results that it is sequential for RX and low throughout, change RX to parallel for the two parts will increase throughout. This patch move the indication to a workqueue, it results in significant performance improvement on RX path. Udp rx throughout is 200Mbps without this patch, and it arrives 400Mbps with this patch. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWPZ-1 Signed-off-by:

The max bundle size support by firmware is 32, change it from 8 to 32 will help performance. This results in significant performance improvement on RX path. The real max rx bundle is decided in ath10k_htc_wait_target(), it is the min value of HTC_HOST_MAX_MSG_PER_RX_BUNDLE and the value reported from firmware. So this change shouldn't cause any regressions with other hardware supported by ath10k. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWPZ-1. Signed-off-by:

The existing implementation of initiating multiple sdio transfers for receive bundling is slowing down the receive speed. Combining the transfers using a bundle method would be ideal. The transmission utilization ratio for sdio bus for small packet is slow, because the space and time cost for sdio bus is same for large length packet and small length packet. So the speed of data for large length packet is higher than small length. Test result of different length of data: data packet(byte) cost time(us) calculated rate(Mbps) 256 28 73 512 33 124 1024 35 234 1792 45 318 14336 168 682 28672 333 688 57344 660 695 Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWPZ-1 Signed-off-by:Alagu Sankar <alagusankar@silex-india.com> Signed-off-by:

Downloading ath10k firmware needs a large number of IOs and cpuidle's miss predictions make it worse. In the worst case, resume time can be three times longer than the average on sdio. This patch disables cpuidle during firmware downloading by applying PM_QOS_CPU_DMA_LATENCY in ath10k_download_fw().

Hence remove errornous line 5281 to make the driver actually execute the correct initialization routine for MT7620 chips. As it was requested by Stanislaw Gruszka remove setting values of MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO power-safe mode (which is disabled), hence we can drop setting it. TX_PIN_CFG is set correctly in other functions, and as setting this value breaks some devices, rather don't set it here during init, but only modify it later on.

The LPS threshold was set to 2, means driver will leave LPS mode if there is more than 2 frames TX/RX for every 2 seconds. This makes driver enter/leave LPS frequently even if we just "ping -i1" to the others. Apparently we do not want to leave LPS mode if there is only some background traffics or web surfing. By experiment, set this to 50 is a more reasonable value to lower the over all power consumption. Signed-off-by:

ThinkPad Thunderbolt 3 Dock Gen 2 is another docking station that uses RTL8153 based USB ethernet. The device supports macpassthru, but it failed to pass the test of -AD, -BND and -BD. Simply bypass these tests since the device supports this feature just fine. Also the ACPI objects have some differences between Dell's and Lenovo's, so make those ACPI infos no longer hardcoded.
