bail out from the suspend/resume callbacks if d0i3 is used. declare support for ANY wowlan trigger (i.e. normal operation). On resume, we shouldn't execute the d0i3 exit flow (which might disconnect stations, etc.) until mac80211 was resumed. Add new flags to indicate we are in suspend, and call the pending exit work on resume. Since the resume flow can take some time, add a new EXIT_WORK reference type to prevent going back to d0i3 at this stage.

This patch enables Energy Based Scan (EBS) - intended to detect energy on 5 GHz band channels. Passive scan on this band takes up to 2.64 sec assuming 110mSec per-channel * 24 channels. EBS is designed to detect energy on channels with intensive Wifi activity as well as those where only beacons are transmitted. EBS completes sampling all channels within shortest beacon frame transmission time. Total EBS duration is about 100 msec (typical beacon interval). Detecting Wifi activity on 5 GHz band channels can significantly reduce scan duration thus saving time and power. EBS failure reported by FW disables EBS for current connection. It is re-enabled upon new connection attempt on any WLAN interface.

If we have no beacon data before association, delay smart FIFO enablement until after we have this data. Not doing so can cause association failures in extremely silent environments (usually only a shielded box/room) as beacon RX is not sent to the host immediately, and then the association time event ends without the host receiving any beacon even though it was on the air - it's just stuck on the FIFO.

Some scan parameters should be dependent on traffic conditions. Centralize conditions verification in one function and obtain scan max out-of-channel and suspend time in that new function. Rely on bound interfaces indication instead of association state to calculate scan parameters. If no bound interfaces use default values for out-of-channel and suspend time parameters. Additionally, get rid of NL80211_SCAN_FLAG_LOW_PRIORITY checks since no use case for this exists so far.

When the firmware asserts, the driver will dump the firmware state to an internal buffer. This buffer is kept aside until it is dumped through debugfs. Once an external application fetched the data, the buffer is freed and a new buffer can be allocated in case another assert occurs. A udev event is sent to trigger an external application. A simple rule like: DRIVER=="iwlwifi", ACTION=="change", RUN+="/sbin/dump_sram.sh" can fetch the data from debugfs. Here is my dump_sram.sh: phyname=$(basename ${DEVPATH}) date=$(date +%F_%H_%M) filename=/var/log/iwl-sram-${phyname}-${date}.bin cat /sys/kernel/debug/ieee80211/${phyname}/iwlwifi/iwlmvm/fw_error_dump > ${filename} The current SRAM size is 80KB so, currently: $ ls -lh iwl-sram-phy0-2014-03-16_13_14.bin -rw-r--r-- 1 emmanuel emmanuel 81K Mar 16 13:15 iwl-sram-phy0-2014-03-16_13_14.bin and after compression: $ ls -lh iwl-sram-phy0-2014-03-16_13_14.bin.xz -rw-r--r-- 1 emmanuel emmanuel 13K Mar 16 13:15 iwl-sram-phy0-2014-03-16_13_14.bin.xz Signed-off-by: NEmmanuel Grumbach <emmanuel.grumbach@intel.com>

In order to restore the qos seq number on d0i3 exit, we need to read it from the wowlan status. However, in order to make sure we use correct seq num for tx frames, we need to defer any outgoing frames, and re-enqueue them only after the seq num is configured correctly. Sync new Tx aggregations with D0i3 so that the correct seq num is used for them. Wait synchronously for D0i3 exit before starting a new Tx agg.

A scheduled scan is a more persistent setting and should take priority over temporary regular scans. Abort the regular when a sched_scan request arrives and then request the sched_scan. The kernel API allows sending a sched_scan without canceling a regular scan in progress, so this is our way to abstract the FW's limitations. Make the scan-cancel Rx handler async and flush after invocation to ensure new scans can't creep in before it.

cfg80211 assumes a scheduled scan is stopped synchronously. Wait for the FW before returning to caller. Don't do anything in the async handler in the stop-from-above flow. There's no need to call the mac80211 sched-scan completion as the cleanup will be automatic. Make sure the async handler is called before the next incoming scan changes the scan_status by flushing the async handlers after all invocations.

The main complexity of the power code is that it needs to take into account the firmware limitations. These limitations state that we need to have a global picture of the vifs present in the system to be able to decide if we can enable power management on a specific vif. Even device power save (as opposed to vif power management) must be disabled in certain circumstances (monitor vif). Refactor the current code to make this clearer by defining a function that explicitely computes these constraints. Signed-off-by: NEmmanuel Grumbach <emmanuel.grumbach@intel.com>

Some older versions of wpa_supplicant don't necessarily stop scheduled scan before starting a regular scan, and there's nothing in the API that requires it either. As a consequence our driver's behaviour of not allowing scan while scheduled scan was in progress broke userspace. However, it is valid to unilaterally stop scheduled scan at any point in time, so when a regular scan request comes just abort the scheduled scan and run the regular scan.
