2016-03-10brcmfmac: Remove waitqueue_active checkHui Wang1-4/+2
We met a problem of pm_suspend when repeated closing/opening the lid on a Lenovo laptop (1/20 reproduce rate), below is the log: [ 199.735876] PM: Entering mem sleep [ 199.750516] e1000e: EEE TX LPI TIMER: 00000011 [ 199.856638] Trying to free nonexistent resource <000000000000d000-000000000000d0ff> [ 201.753566] brcmfmac: brcmf_pcie_suspend: Timeout on response for entering D3 substate [ 201.753581] pci_legacy_suspend(): brcmf_pcie_suspend+0x0/0x1f0 [brcmfmac] returns -5 [ 201.753585] dpm_run_callback(): pci_pm_suspend+0x0/0x160 returns -5 [ 201.753589] PM: Device 0000:04:00.0 failed to suspend async: error -5 Through debugging, we found when problem happens, it is not the device fails to enter D3, but the signal D3_ACK comes too early to pass the waitqueue_active() check. 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.

2016-03-09iwlwifi: mvm: don't try to offload AES-CMAC in AP/IBSS modesJohannes Berg1-1/+5
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 <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2016-03-09iwlwifi: mvm: adapt the firmware assert log to new firmwareEmmanuel Grumbach3-33/+30
Newer firmware versions put different data in the memory which is read by the driver upon firmware crash. Just change the variable names in the code and the name of the data in the log that we print withouth any functional change. 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 <[email protected]>
2016-03-09iwlwifi: pcie: avoid restocks inside rx loop if not emergencyGregory Greenman1-26/+33
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. Signed-off-by: Gregory Greenman <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2016-03-09iwlwifi: mvm: return the cooling state index instead of the budgetChaya Rachel Ivgi2-29/+31
iwl_mvm_tcool_get_cur_state is the function that returns the cooling state index to the sysfs handler. This function returns mvm->cooling_dev.cur_state but that variable was set to the budget and not the cooling state index. Fix that. Add a missing blank line while at it.

2016-03-09iwlwifi: mvm: don't let NDPs mess the packet trackingEmmanuel Grumbach1-3/+26
We need to track the next packet that we will reclaim in order to know when the Tx queues are empty. 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. Reported-by: Alesya Shapira <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2016-03-09iwlwifi: add support for getting HW address from CSRSara Sharon4-22/+68
From 9000 family on, we need to get HW address from host CSR registers. OEM can override it by fusing the override registers - read those first, and if those are 0 - read the OTP registers instead. In addition - bail out if no valid mac address is present. Make it shared for all NICs. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2016-03-09iwlwifi: pcie: fine tune number of rxbsSara Sharon3-9/+13
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.

2016-03-09iwlwifi: mvm: ROC: cleanup time event info on FW failureMatti Gottlieb1-11/+4
Currently when the FW sends start/stop aux roc time event notification with an error status, the driver returns an error value, but does not remove the time event, and does not notify the stack above that the time event is over. This causes problems that the stack above assumes we are still in the middle of a time event, and therefore can block different events, such as scanning. On FW failure notification, cleanup the time event parameters and notify the stack above that the time event is over.

2016-03-08wireless: cw1200: use __maybe_unused to hide pm functions_Arnd Bergmann2-9/+9
The cw1200 uses #ifdef to check for CONFIG_PM, but then uses SIMPLE_DEV_PM_OPS, which leaves the references out when CONFIG_PM_SLEEP is not defined, so we get a warning with PM=y && PM_SLEEP=n: drivers/net/wireless/st/cw1200/cw1200_spi.c:450:12: error: 'cw1200_spi_suspend' defined but not used [-Werror=unused-function] This removes the incorrect #ifdef and instead uses a __maybe_unused annotation to let the compiler know it can silently drop the function definition. For the DEV_PM_OPS definition, we can use an IS_ENABLED() check to avoid defining the structure when CONFIG_PM is not set without the #ifdef.
