2020-04-22ath10k: add htt TX bundle for sdioWen Gong1-0/+8
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/+5
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
2019-06-25ath10k: add inline wrapper for htt_h2t_aggr_cfg_msgErik Stromdahl1-1/+1
This is done in order to make the *htt_h2t_aggr_cfg_msg* op align better with the rest of the htt ops (whom all have inline wrappers). It also adds support for the case when the op is missing (function pointer is NULL). As a result of this, the name of the 32 bit implementation in htt_tx.c was changed and the function was made static.

2015-07-02ath10k: configure frag desc memory to target for qca99X0Raja Mani1-0/+4
Pre qca99X0 chipsets follows the model where dynamically allocate memory for frag desc on getting new skb for TX. But, this is not going to be the case in qca99X0. It expects frag desc memory to be allocated at boot time and let the driver to reuse allocated memory after every TX completion. So there won't be any dynamic frag memory memory allocation in qca99X0 during data transmission. qca99X0 hardware doesn't need fragment desc address to be programmed in msdu descriptor for every data transaction. It needs to know only starting address of fragment descriptor at the time of the boot. During data transmission, qca99X0 hardware can retrieve corresponding frag addr by adding programmed frag desc base addr + msdu id. Allocate continuous fragment descriptor memory (same size as number of descriptor) at the time of target initialization and configure allocated dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG. How this is allocated continuous memory is going to be used is not covered in this patch. It just allocates memory and hand over to firmware. If we don't do it at init time, qca99X0 will stall when firmware tries to do TX. Signed-off-by: Raja Mani <rmani@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2015-03-30ath10k: add ATH10K_FW_IE_HTT_OP_VERSIONRajkumar Manoharan1-0/+98
Target to host HTT messages are conflicting between 10.x and other firmware revisions. By maintaining separate HTT T2H tables for each firmware revisions (main, 10x and tlv) similar to WMI abstraction, solves the conflicts. Add ATH10K_FW_IE_HTT_OP_VERSION so that the firmware can advertise the HTT interface to ath10k. This fix is needed to get management frames over HTT (ie. ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX disabled) working with 10.2.4.48-2 firmware. Otherwise there will be unknown htt events and nothing works: [30087.438343] ath10k_pci 0000:02:00.0: htt event (19) not handled [30087.448691] ath10k_pci 0000:02:00.0: htt event (19) not handled [30149.032974] ath10k_pci 0000:02:00.0: htt event (19) not handled If the firmware does not have ATH10K_FW_IE_HTT_OP_VERSION use the main HTT interface.
