| | | | | | | | | | | | | | | | | | | | | | | | For the messages from host to target, shadow copy of CE descriptors are maintained in source ring.

| | | | | | | | | | | | | | | | | | | | | | | | The physical address necessary to unmap DMA ('bufferp') is stored in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id when handling send completion (htc ep id is stored in sk_buff control buffer). So the unused output arguments {bufferp, nbytesp and transfer_idp} are removed from CE send completion. This change is needed before removing the shadow copy of copy engine (CE) descriptors in follow up patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | European Union has made it mandatory that all devices working in 2.4 GHz has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1) beginnig this year. The standard basically speaks about interferences in 2.4Ghz band. For example, when 802.11 device detects interference, TX must be stopped as long as interference is present. Adaptive CCA is a feature, when enabled the device learns from the environment and configures CCA levels adaptively. This will improve detecting interferences and the device can stop trasmissions till the interference is present eventually leading to good performances in varying interference conditions. The patch includes code for enabling adaptive CCA for 10.2.4 firmware on QCA988X.

* | wcn36xx: introduce per-channel ring buffer locksBob Copeland2015-10-282-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wcn36xx implements a ring buffer for transmitted frames for each (high and low priority) DMA channel. The ring buffers are lockless: new frames are inserted at the head of the queue, while finished packets are reaped from the tail. Unfortunately, the list manipulations are missing any kind of barriers so are susceptible to various races: for example, a TX completion handler might read an updated desc->ctrl before the head has actually advanced, and then null out the ctl->skb pointer while it is still being used in the TX path. Simplify things here by adding a spin lock when traversing the ring. This change increased stability for me without adding any noticeable overhead on my platform (xperia z).

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".

| | * | ath10k: select board data based on BMI chip id and board idManikanta Pubbisetty2015-10-144-8/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QCA99X0 uses radio specific board names based on chip id and board id combinations. We get these IDs from the target using BMI after otp.bin has been started. This patch reorders the call to the function ath10k_core_fetch_board_file so that we have OTP binary before requesting for boardid-chipid. We get this OTP data after parsing firmware-N.bin.

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.
