2023-11-30wifi: ath10k: Use DECLARE_FLEX_ARRAY() for ath10k_htc_recordJeff Johnson1-3/+3
Transform the zero-length arrays in ath10k_htc_record into proper flexible arrays via the DECLARE_FLEX_ARRAY() macro. This helps with ongoing efforts to globally enable -Warray-bounds.

2020-04-22ath10k: enable alt data of TX path for sdioWen Gong1-2/+11
The default credit size is 1792 bytes, but the IP mtu is 1500 bytes, then it has about 290 bytes's waste for each data packet on sdio transfer path for TX bundle, it will reduce the transmission utilization ratio for data packet. This patch enable the small credit size in firmware, firmware will use the new credit size 1556 bytes, it will increase the transmission utilization ratio for data packet on TX patch. It results in significant performance improvement on TX path. This patch only effect sdio chip, it will not effect PCI, SNOC etc. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWP-1.

2020-04-22ath10k: add htt TX bundle for sdioWen Gong1-2/+22
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 This patch change the TX packet from single packet to a large length bundle packet, max size is 32, it results in significant performance improvement on TX path. Also there's a fourth thread "ath10k_tx_complete_wq" added to ath10k as it improves TCP RX throughput (values in Mbps): TCP-RX TCP-TX UDP-RX UDP-TX use workqueue_tx_complete 423 357 448 412 change it to ar->workqueue 410 360 449 414 change it to ar->workqueue_aux 405 339 446 401 This patch only effect sdio chip, it will not effect PCI, SNOC etc. It only enable bundle for sdio chip.

2020-04-09ath10k: disable TX complete indication of htt for sdioWen Gong1-0/+3
For sdio chip, it is high latency bus, all the TX packet's content will be tranferred from HOST memory to firmware memory via sdio bus, then it need much more memory in firmware than low latency bus chip, for low latency chip, such as PCI-E, it only need to transfer the TX descriptor via PCI-E bus to firmware memory. For sdio chip, reduce the complexity of TX logic will help TX efficiency since its memory is limited, and it will reduce the TX circle's time of each packet and then firmware will have more memory for TX since TX complete also need memeory. This patch disable TX complete indication from firmware for htt data packet, it will not have TX complete indication from firmware to ath10k. It will cut the cost of bus bandwidth of TX complete and make the TX logic of firmware simpler, it results in significant performance improvement on TX path. Udp TX throughout is 130Mbps without this patch, and it arrives 400Mbps with this patch. The downside of this patch is the command "iw wlan0 station dump" will show 0 for "tx retries" and "tx failed" since all tx packet's status is success. This patch only effect sdio chip, it will not effect PCI, SNOC etc. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWPZ-1 Signed-off-by: Wen Gong <wgong@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20200212080415.31265-2-wgong@codeaurora.org
2019-12-02ath10k: change bundle count for max rx bundle for sdioWen Gong1-4/+6
For max bundle size 32, the bundle mask is not same with 8/16. Change it to match the max bundle size of htc. Otherwise it will not match with firmware, for example, when bundle count is 17, then flags of ath10k_htc_hdr is 0x4, if without this patch, it will be considered as non-bundled packet because it does not have mask 0xF0, then trigger error message later: payload length 56747 exceeds max htc length: 4088. htc->max_msgs_per_htc_bundle is the min value of HTC_HOST_MAX_MSG_PER_RX_BUNDLE and msg->ready_ext.max_msgs_per_htc_bundle of ath10k_htc_wait_target, it will be sent to firmware later in ath10k_htc_start, then firmware will use it as the final max rx bundle count, in WLAN.RMH.4.4.1-00029, msg->ready_ext.max_msgs_per_htc_bundle is 32, it is same with HTC_HOST_MAX_MSG_PER_RX_BUNDLE, so the final max rx bundle count will be set to 32 in firmware. This patch only effect sdio chips. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

2019-11-25ath10k: change max RX bundle size from 8 to 32 for sdioWen Gong1-2/+19
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.

2019-02-12ath10k: migrate to mac80211 txq schedulingToke Høiland-Jørgensen1-1/+0
ath10k maintains common txqs list for all stations. This txq management can be removed by migrating to mac80211 txq APIs and let mac80211 handle txqs reordering based on reported airtime. By doing this, txq fairness maintained in ath10k i.e processing N frames per txq is removed. By adapting to mac80211 APIs, ath10k will support mac80211 based airtime fairness algorithm.

2018-06-28ath10k: replace hardcoded constant with defineErik Stromdahl1-0/+1
The hardcoded values used in ath10k_mac_tx_push_pending and ath10k_mac_op_wake_tx_queue set an upper limit of how many packets that can be consumed from the TX queue. HTC_HOST_MAX_MSG_PER_TX_BUNDLE is a proper name for this constant, as the value effectively limits the number of messages that can be consumed in one step. Thus, the value is an upper limit of the number of messages that can be added to a TX message bundle.

The patch removes HTC endpoint tx workers in favour of direct command submission.

It's possible to push more traffic than the device/system is able to handle and have no hiccups or performance degradation with UDP traffic.
