2019-11-29ath11k: Fixing TLV length issue in peer pktlog WMI commandVikas Patel
TLV length was 0 for TLV tag 'WMI_TAG_ARRAY_STRUCT' causing Q6 to crash when trying to configure pktlog filter via debugfs. Signed-off-by: Vikas Patel <vikpatel@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-11-29ath11k: Fix skb_panic observed during msdu coalescingSriram R
skb_panic is hit during msdu coalescing whenever enough tailroom is not allocated based on the remaining msdu length which is spread across in different rx buffers. Compute the extra length for resizing the skb based on the total msdu length and the msdu length of the first buffer.

2019-11-29ath11k: avoid WMM param truncationKarthikeyan Periyasamy
In conf_tx() mac operation callback, we are truncating the tx params cw_min and cw_max due to lower data type cast. so modified the data type of cwmin and cwmax to avoid the trucation issue.

2019-11-29ath11k: optimize RX path latencyJohn Crispin
This patch drops ath11k_hal_rx_parse_dst_ring_desc(). This function was creating a huge amount of load, which lead to a signifcant latency delay when processing data in the RX path. Pegging the processing on a specific core and running perf --top we get the following output when running HE80 at a fixed bandwidth of 1gbit. with patch 19.19% [ath11k] [k] ath11k_dp_process_rx 5.02% [ath11k] [k] ath11k_dp_rx_tid_del_func 4.39% [kernel] [k] v7_dma_inv_range 4.15% [kernel] [k] __slab_alloc.constprop.1 4.03% [kernel] [k] dev_gro_receive 3.86% [kernel] [k] tcp_gro_receive 3.07% [ip_tables] [k] ipt_do_table 2.96% [kernel] [k] dma_cache_maint_page without patch 21.64% [ath11k] [k] ath11k_hal_rx_parse_dst_ring_desc 10.80% [ath11k] [k] ath11k_dp_process_rx 3.77% [kernel] [k] v7_dma_inv_range 3.48% [kernel] [k] dev_gro_receive 3.32% [ath11k] [k] ath11k_dp_rx_tid_del_func 3.17% [mac80211] [k] ieee80211_rx_napi 2.70% [kernel] [k] dma_cache_maint_page 2.65% [mac80211] [k] ieee80211_sta_ps_transition When removing the the bandwidth limit and rerunning the test we see an overall throughput improvement of 3-400mbit when running 4x4 HE80.

2019-11-29ath11k: update tcl cmd descriptor parameters for STA modeAnilkumar Kolli
It is observed that ath11k STA mode UL throughput is low. This is due to packets delivered to FW from TCL instead of TQM. TCL AST search fail causes packet delivered to FW, fix this by properly configuring the TCL address search type and ast_hash. STA UL throughput is improved 10times with 11AC AP.

2019-11-27ath11k: fix missed bw conversion in tx completionTamizh chelvam
TX rate stats for the retried packets for a station comes through tx completion events. Assigning hw reported bandwidth information directly to station's txrate bandwidth will cause below warning. Fix this warning by converting the hw reported bandwidth to mac80211 base bandwidth.

2019-11-25ath11k: driver for Qualcomm IEEE 802.11ax devicesKalle Valo
ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k uses mac80211 and supports AP, Station and Mesh modes. Even though ath11k has some similar code as with ath10k (especially the WMI layer) it was concluded to be simpler to have a "clean start" for ath11k code base and not try to share the code with ath10k. This makes maintenance easier and avoids major changes in ath10k, which would have significantly increased the risk of regressions in existing setups. Even though the driver is very similar with ath10k but there are major differences as well. The datapath is completely different. ath11k supports multiple MACs, called "soc" in the firmware interface. And there's only one WMI interface to support. Currently ath11k supports only IEEE 802.11ac mode, but patches for 802.11ax are available and they will be submitted after ath11k is accepted to upstream. The firmware images are available from ath11k-firmware repository but they will be also submitted to linux-firmware: https://github.com/kvalo/ath11k-firmware This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1. The driver has had multiple authors who are listed in alphabetical order below.
