2015-10-29ath10k: remove shadow copy of CE descriptors for source ringRajkumar Manoharan3-33/+0
For the messages from host to target, shadow copy of CE descriptors are maintained in source ring. Before writing actual CE descriptor, first shadow copy is filled and then it is copied to CE address space. To optimize in download path and to reduce d-cache pressure, removing shadow copy of CE descriptors. This will also reduce driver memory consumption by 33KB during on device probing.

2015-10-29ath10k: cleanup copy engine send completionRajkumar Manoharan3-50/+12
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.

2015-10-29ath10k: use local memory instead of shadow descriptor in ce_sendRajkumar Manoharan1-7/+6
Currently to avoid uncached memory access while filling up copy engine descriptors, shadow descriptors are used. This can be optimized further by removing shadow descriptors. To achieve that first shadow ring dependency in ce_send is removed by creating local copy of the descriptor on stack and make a one-shot copy into the "uncached" descriptor.

2015-10-28ath10k: enable adaptive CCAMaharaja6-0/+85
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.

2015-10-28ssb: pick PCMCIA host code support from b43 driverRafał Miłecki5-194/+1
ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO. Every ssb bus contains cores AKA devices. The main idea is to have ssb driver scan/initialize bus and register ready-to-use cores. This way ssb drivers can operate on a single core mostly ignoring underlaying details. For some reason PCMCIA support was split between ssb and b43. We got PCMCIA host device probing in b43, then bus scanning in ssb and then wireless core probing back in b43. The truth is it's very unlikely we will ever see PCMCIA ssb device with no 802.11 core but I still don't see any advantage of the current architecture. With proposed change we get the same functionality with a simpler architecture, less Kconfig symbols, one killed EXPORT and hopefully cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb specific code in ssb driver. This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We already use similar solution with b43_pci_bridge.c. I didn't use "b43" in name of this new file as in theory any driver can operate on wireless core.

2015-10-28mwifiex: toggle carrier state in start_ap/stop_ap.Marty Faltesek2-7/+8
In uap mode the carrier is not enabled until after the first STA joins. The carrier triggers the bridge to start its state machine, and if STP is enabled, it takes 4 seconds as it transitions from disabled to forwarding. During this time the bridge drops all traffic, and the EAPOL handshake times out after 3 seconds, preventing stations from joining. Follow the logic used in mac80211 and start the carrier in start_ap and disable it in stop_ap. This has a nice benefit of allowing the first station connection time to be reduced by up to 75% when STP is in use.

2015-10-28wcn36xx: introduce per-channel ring buffer locksBob Copeland2-8/+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).

2015-10-25iwlwifi: mvm: take scan ref only on successEliad Peller1-9/+6
In some cases, scan reference was taken, but wasn't released even though scan command wasn't actually issued. Change the current code to simply take the reference only on success. Signed-off-by: Eliad Peller <eliadx.peller@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-10-25iwlwifi: mvm: remove pointless scan plan checksJohannes Berg1-14/+0
As cfg80211 already enforces these limits, there's little point in having them again here in our code. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2015-10-25iwlwifi: mvm: Implement per vif frame registration APIAndrei Otcheretianski2-0/+25
Implement config_iface_filter() driver op. Currently support only probe request registration for p2p client vifs, by setting MAC_FILTER_IN_PROBE_REQUEST flag in MAC_CONTEXT_CMD. This is needed since WFDS spec and certification require a P2P client to be discoverable on its operating channel.

2015-10-25iwlwifi: avoid read/write operations if the bus is deadEliad Peller2-0/+8
Recovery takes too much time if the bus is dead (each timeout is 2000ms, etc.). Explicitly skip fw dump in this case, as it will result in garbage data (and might take signifcant time) Signed-off-by: Eliad Peller <eliadx.peller@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-10-25iwlwifi: mvm: Add support for two scheduled scan plansAvraham Stern3-42/+87
Add support for two scan plans for scheduled scan. The first plan will run for a limited number of iterations, then the second plan will run infinitely. Signed-off-by: Avraham Stern <avraham.stern@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-10-25iwlwifi: mvm: let any command flag be passed to iwl_mvm_flushtx_path()Luca Coelho6-10/+8
Instead of only allowing the caller to decide whether the CMD_ASYNC flag is set, let it pass the entire flags bitmask. This allows more flexibility and will be needed when we call this function in the suspend flow (where other flags are needed).

2015-10-25iwlwifi: mvm: use short timeouts in P2P low latency if supportedJohannes Berg3-7/+24
Those timeouts are used for AM-to-PSM transition. We already have those pairs defined for default and WOWLAN use cases. We expect that by using shorter threshold for low latency P2P, e.g. for Miracast video scenario, we might save a considerable amount of power.
