2015-10-24rtl8xxxu: move devices supported by rtlwifi under UNTESTED configKalle Valo1-1/+2
There are still four devices which are currently supported both by the new rtl8xxxu driver and rtlwifi. To not break existing setups enable the support for these four devices only when CONFIG_RTL8XXXU_UNTESTED is turned on. Once rtl8xxxu support is found to be good enough the devices can be removed from rtlwifi and enabled by default in rtl8xxxu.

2015-10-21New driver: rtl8xxxu (mac80211)Jes Sorensen8-0/+7677
This is an alternate driver for a number of Realtek WiFi USB devices, including RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU. It was written from scratch utilizing the Linux mac80211 stack. After spending months cleaning up the vendor provided rtl8723au driver, which comes with it's own 802.11 stack included, I decided to rewrite this driver from the bottom up. Many thanks to Johannes Berg for 802.11 insights and help and Larry Finger for help with the vendor driver. The full git log for the development of this driver can be found here: git git://git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git branch rtl8723au-mac80211 This driver is still under development, but has proven to be very stable for me. It currently supports station mode only. It has support for OFDM and CCK rates. It does lack certain features found in the staging driver, such as power management, AMPDU, and 40MHz channel support. In addition it does not support AD-HOC, AP, and monitor mode support at this point. The driver is known to work with the following devices: Lenovo Yoga (rtl8723au) TP-Link TL-WN823N (rtl8192cu) Etekcity 6R (rtl8188cu) Daffodil LAN03 (rtl8188cu) Alfa AWUS036NHR (rtl8188ru) Signed-off-by: Jes Sorensen <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

2015-10-19ath10k: disable PCI PS for QCA988X and QCA99X0Anilkumar Kolli2-1/+88
This patch disables PCI PS for QCA988X and QCA99X0, Since PCI PS is validated for QCA6174, let it be enabled only for QCA6174. 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.

2015-10-16ath10k: configure copy engine 5 for HTT messagesRajkumar Manoharan1-11/+59
Currently target to host (T2H) HTT messages are received at copy engine 1. 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".

QCA6174 needs different board files based on board type. 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.
