* | | airo: Track APList_rid in struct airo_infoOndrej Zary2015-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of dynamically allocating APList, make it a member of struct airo_info to always track state of APList_rid. This simplifies suspend/resume and allows removal of readAPListRid. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

It would be better to execute PCI PS related functions only for the supported devices. PCI time out issue is observed with QCA99X0 on x86 platform, We will disable PCI PS for QCA988X and QCA99X0 until PCI PS is properly implemented. Taking and releasing ps_lock is causing higher CPU consumption. Michal Kazior suggested ps_lock overhead to be reworked so that ath10k_pci_wake/sleep functions are called less often, i.e. move the powersave logic up (only during irq handling, tx path, submitting fw commands) but that's a bigger change and can be implemented later.

These messages are processed by HTC layer in both host and target. To avoid HTC level processing overhead in both host and target, the unused copy engine 5 is being used for receiving HTT T2H messages. This will speedup the receive data processing as well as htt tx completion. Hence host and target copy engine configuration tables are updated to enable CE5 pipe. The in-direction HTT mapping is now pointing to CE5 for all HTT T2H. Moreover HTT send completion messages are polled from HTC handler as CE 4 is not interrupt-driven. For faster tx completion, CE4 polling needs to be done whenever CE pipe which transports HTT Rx (target->host) is processed. This avoids overhead of polling HTT messages from HTC layer. Servicing CE 4 faster is helping to solve "failed to transmit packet, dropping: -105".

To make it easier to distribute multiple board files and automatically choose correct board file create a simple TLV file format following the same principles as with FW IEs. The file is named board-2.bin and contain multiple board files. Each board file then can have multiple names. ath10k searches for file board-N.bin (where N is the interface version number for the board file, just like we for firmware files) in /lib/firmware/*, for example for qca99x0 it will try to find it here: /lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin If ath10k doesn't find board-2.bin then it will fallback to the old board.bin file. This patch adds a simple name scheme using pci device id which for now will be used by qca6174: bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x This removes the old method of having subsystem ids in ar->spec_board_id and using that in the board file name.

This did not work so far and is fixed with this patch. The modification does not change detection performance within the driver, since it only ensures early reset (which is later performed by the PRI detectors anyway). It is relevant for synthetic tests and statistical evaluations, where millions of pulse patterns are processed and an early reset helps reducing load.

This stops NAPI polling and re-enables the Rx interrupt. However, in cases where no more frames received, interrupt will not be triggered and rest of Rx frames will not be processed. Skip bad frames and continue to reap Rx packets when such frames are encountered, and add statistics for such frames for debug.

On post rx processing path, skb allocation and dma mapping are unnecessarily handled within ce_lock. This is affecting peak throughput and also causing more CPU consumption. Optimize this by acquiring ce_lock only when accessing copy engine ring and moving skb allocation out of ce_lock. In AP148 platform with QCA99x0 in conducted environment, UDP uplink peak throughput is improved from ~1320 Mbps to ~1450 Mbps and TCP uplink peak throughput is increased from ~1240 Mbps (70% host CPU load) to ~1300 Mbps (71% CPU load). Similarly ~40Mbps improvement is observed in downlink path. Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
