Just like this: brcmf_pcie_send_mb_data(devinfo, BRCMF_H2D_HOST_D3_INFORM); // signal is triggered here wait_event_timeout(devinfo->mbdata_resp_wait, devinfo->mbdata_completed, BRCMF_PCIE_MBDATA_TIMEOUT); So far I think it is safe to remove waitqueue_active check since there is only one place to trigger this signal (sending BRCMF_H2D_HOST_D3_INFORM). And it is not a problem calling wake_up event earlier than calling wait_event.

| | * iwlwifi: mvm: don't try to offload AES-CMAC in AP/IBSS modesJohannes Berg2016-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The firmware/hardware only supports checking AES-CMAC on RX, not using it on TX. For station mode this is fine, since it's the only thing it will ever do. For AP mode, it never receives such frames, but must be able to transmit them. This is currently broken since we try to enable them for hardware crypto (for RX only) and then treat them as TX_CMD_SEC_EXT, leading to FIFO underruns during TX so the frames never go out to the air. To fix this, simply use software on TX in AP (and IBSS) mode. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer firmware versions put different data in the memory which is read by the driver upon firmware crash.

On older firmware, there will be a mismatch between the names that are printed and the content itself, but that's harmless. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
| | * iwlwifi: pcie: avoid restocks inside rx loop if not emergencyGregory Greenman2016-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When trying to reach high Rx throughput of more than 500Mbps on a device with a relatively weak CPU (Atom x5-Z8500), CPU utilization may become a bottleneck. Analysis showed that we are looping in iwl_pcie_rx_handle for very long periods which led to starvation of other threads (iwl_pcie_rx_handle runs with _bh disabled). We were handling Rx and allocating new buffers and the new buffers were ready quickly enough to be available before we had finished handling all the buffers available in the hardware. As a consequence, we called iwl_pcie_rxq_restock to refill the hardware with the new buffers, and start again handling new buffers without exiting the function. Since we read the hardware pointer again when we goto restart, new buffers were handled immediately instead of exiting the function. This patch avoids refilling RBs inside rx handling loop, unless an emergency situation is reached. It also doesn't read the hardware pointer again unless we are in an emergency (unlikely) case. This significantly reduce the maximal time we spend in iwl_pcie_rx_handle with _bh disabled.

This is useful when we open or tear down an A-MPDU session which requires to switch queue. The next packet being reclaimed is identified by its WiFi sequence number and this is relevant only when we use QoS. QoS NDPs do have a TID but have a meaningless sequence number. The spec mandates the receiver to ignore the sequence number in this case, allowing the transmitter to put any sequence number. Our implementation leaves it 0. When we reclaim a QoS NDP, we can't update the next_relcaim counter since the sequence number of the QoS NDP itself is invalid. We used to update the next_reclaim based on the sequence number of the QoS NDP which reset it to 1 (0 + 1) and because of this, we never knew when the queue got empty. This had to sad consequence to stuck the A-MPDU state machine in a transient state. To fix this, don't update next_reclaim when we reclaim a QoS NDP. Alesya saw this bug when testing u-APSD. Because the A-MPDU state machine was stuck in EMPTYING_DELBA, we updated mac80211 that we still have frames for that station when it got back to sleep. mac80211 then wrongly set the TIM bit in the beacon and requested to release non-existent frames from the A-MPDU queue. This led to a situation where the client was trying to poll frames but we had no frames to send.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We kick the allocator when we have 2 RBDs that don't have attached RBs, and the allocator allocates 8 RBs meaning that it needs another 6 RBDs to attach the RBs to. The design is that allocator should always have enough RBDs to fulfill requests, so we give in advance 6 RBDs to the allocator so that when it is kicked, it gets additional 2 RBDs and has enough RBDs. These RBDs were taken from the Rx queue itself, meaning that each Rx queue didn't have the maximal number of RBDs, but MAX - 6. Change initial number of RBDs in the system to include both queue size and allocator reserves. Note the multi-queue is always 511 instead of 512 to avoid a full queue since we cannot detect this state easily enough in the 9000 arch.

| * | rtlwifi: Fix size of wireless mode variableLarry Finger2016-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Smatch reports the following warning: CHECK drivers/net/wireless/realtek/rtlwifi/rc.c drivers/net/wireless/realtek/rtlwifi/rc.c:144 _rtl_rc_rate_set_series() warn: impossible condition '(wireless_mode == 256) => (0-255 == 256)' This warning arises because commit acc6907b87a9 ("rtlwifi: Fix warning from ieee80211_get_tx_rates() when using 5G") now checks the wireless mode for WIRELESS_MODE_AC_ONLY (BIT(8)) in _rtl_rc_rate_set_series(). As a result, all quantities used to store the wireless mode must be u16. This patch also reorders struct rtl_sta_info to save a little space.
