2014-11-11iwlwifi: mvm: rs - don't use the shared antenna when BT load is highEmmanuel Grumbach4-0/+40
When we need only one antenna, we should refrain from using the antenna that is shared with BT if BT load is high. Fix this. Reviewed-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-11-11iwlwifi: mvm: rs: fix getting stuck in a test windowEyal Shapira1-7/+6
When Tx STBC is being used and RS switches to a search column using the alternate antenna from the current one there is a problem with using rs_rate_match to figure out which table is the active and which one is the search one. The root cause is because in STBC the antenna mask in the ucode rate is set to ANT_AB and in this specific scenario it matches both the active and search table (e.g. SISO_ANT_A and SISO_ANT_B). This leads to tx stats being updated in the wrong table and later on to getting stuck in a test window and not moving on to other columns. If this happens during the initial search cycle we never end it and therefore never enable aggregation which leads naturally to severe througput degradation. Fix it by deducing which table is which by knowing whether we're in a search or not like it's being done in rs_rate_scale_perform Signed-off-by: Eyal Shapira <eyalx.shapira@intel.com> Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-11-11iwlwifi: mvm/trans: abort d0i3_enter in case of held refEliad Peller4-1/+35
Other contexts might call iwl_mvm_ref_sync() right before we set IWL_MVM_STATUS_IN_D0I3, and then assume the fw/bus is not in d0i3 state. However, since we currently don't check for held references in the d0i3_enter flow, we might enter d0i3 although there is an active reference. Solve it by aborting the d0i3 enter flow if there is an active reference. Since users are assumed to use iwl_mvm_ref_sync, which takes a ref before checking the flag, we don't need further locking.

2014-10-23iwlwifi: dvm: drop non VO frames when flushingEmmanuel Grumbach1-11/+13
When mac80211 wants to ensure that a frame is sent, it calls the flush() callback. Until now, iwldvm implemented this by waiting that all the frames are sent (ACKed or timeout). In case of weak signal, this can take a significant amount of time, delaying the next connection (in case of roaming). Many users have reported that the flush would take too long leading to the following error messages to be printed: iwlwifi 0000:03:00.0: fail to flush all tx fifo queues Q 2 iwlwifi 0000:03:00.0: Current SW read_ptr 161 write_ptr 201 iwl data: 00000000: 00 00 00 00 00 00 00 00 fe ff 01 00 00 00 00 00 [snip] iwlwifi 0000:03:00.0: FH TRBs(0) = 0x00000000 [snip] iwlwifi 0000:03:00.0: Q 0 is active and mapped to fifo 3 ra_tid 0x0000 [9,9] [snip] Instead of waiting for these packets, simply drop them. This significantly improves the responsiveness of the network. Note that all the queues are flushed, but the VO one. This is not typically used by the applications and it likely contains management frames that are useful for connection or roaming. This bug is tracked here: https://bugzilla.kernel.org/show_bug.cgi?id=56581 But it is duplicated in distributions' trackers. A simple search in Ubuntu's database led to these bugs: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1270808 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1305406 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1356236 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1360597 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1361809 Cc: <stable@vger.kernel.org> Depends-on: 77be2c54c5bd ("mac80211: add vif to flush call") Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-10-23iwlwifi: mvm: ROC - bug fixes around time events and lockingMatti Gottlieb2-10/+17
Don't add the time event to the list. We added it several times the same time event, which leads to an infinite loop when walking the list. Since we (currently) don't support more than one ROC for STA vif at a time, enforce this and don't add the time event to any list. We were also missing the locking of the mutex which led to a lockdep splat - fix that.

2014-10-23iwlwifi: mvm: Add tx power condition to bss_info_changed_ap_ibssHaim Dreyfuss1-0/+7
The tx power should be limited from many reasons. currently, setting the tx power is available by the mvm only for station interface. Adding the tx power condition to bss_info_changed_ap_ibss make it available also for AP.

2014-10-23iwlwifi: configure the LTREmmanuel Grumbach6-8/+56
The LTR is the handshake between the device and the root complex about the latency allowed when the bus exits power save. This configuration was missing and this led to high latency in the link power up. The end user could experience high latency in the network because of this.

Pull networking updates from David Miller: "Most notable changes in here: 1) By far the biggest accomplishment, thanks to a large range of contributors, is the addition of multi-send for transmit. This is the result of discussions back in Chicago, and the hard work of several individuals. Now, when the ->ndo_start_xmit() method of a driver sees skb->xmit_more as true, it can choose to defer the doorbell telling the driver to start processing the new TX queue entires. skb->xmit_more means that the generic networking is guaranteed to call the driver immediately with another SKB to send. There is logic added to the qdisc layer to dequeue multiple packets at a time, and the handling mis-predicted offloads in software is now done with no locks held. Finally, pktgen is extended to have a "burst" parameter that can be used to test a multi-send implementation. Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4, virtio_net Adding support is almost trivial, so export more drivers to support this optimization soon. I want to thank, in no particular or implied order, Jesper Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann, David Tat, Hannes Frederic Sowa, and Rusty Russell. 2) PTP and timestamping support in bnx2x, from Michal Kalderon. 3) Allow adjusting the rx_copybreak threshold for a driver via ethtool, and add rx_copybreak support to enic driver. From Govindarajulu Varadarajan. 4) Significant enhancements to the generic PHY layer and the bcm7xxx driver in particular (EEE support, auto power down, etc.) from Florian Fainelli. 5) Allow raw buffers to be used for flow dissection, allowing drivers to determine the optimal "linear pull" size for devices that DMA into pools of pages. The objective is to get exactly the necessary amount of headers into the linear SKB area pre-pulled, but no more. The new interface drivers use is eth_get_headlen(). From WANG Cong, with driver conversions (several had their own by-hand duplicated implementations) by Alexander Duyck and Eric Dumazet. 6) Support checksumming more smoothly and efficiently for encapsulations, and add "foo over UDP" facility. From Tom Herbert. 7) Add Broadcom SF2 switch driver to DSA layer, from Florian Fainelli. 8) eBPF now can load programs via a system call and has an extensive testsuite. Alexei Starovoitov and Daniel Borkmann. 9) Major overhaul of the packet scheduler to use RCU in several major areas such as the classifiers and rate estimators. From John Fastabend. 10) Add driver for Intel FM10000 Ethernet Switch, from Alexander Duyck. 11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric Dumazet. 12) Add Datacenter TCP congestion control algorithm support, From Florian Westphal. 13) Reorganize sk_buff so that __copy_skb_header() is significantly faster.
