* | iwlwifi: mvm: clear tt values when entering CT-killLuciano Coelho2014-12-28
| | | | | | | | | | | | | | | | | | | | | | | | Clear the thermal throttling values when entering CT-kill, since everything will be reinitialized anyway when we exit CT-kill. Additionally, clear the dynamic_smps value in the initialization funciton, for consistency.

* | iwlwifi: mvm: add fw runtime stack to dump dataLiad Kaufman2014-12-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The allocation of the DCCM between the data and the stack can theoretically change without notice to the driver, but the total size is HW-fixed. Since the stack CCM (runtime stack) has also data important to the FW - this patch allows pulling the whole DCCM in one piece and adds it to the dump data. If the size isn't known - just use the data part of the DCCM as it appears in the FW TLVs.

| | | | | | | | | | | | | | | | | | | | | | | | | | When another vif is also running during a channel switch, we need to use a session protection when we move to the new channel, so that we don't miss the beacons. Without this, sometimes the other vif repeatedly gets time exactly when we should be hearing the beacons, preventing channel switch from completing. Adding a session protection that lasts from the moment the channel changes until 2 TBTTs later, ensures that we will hear the beacons on the destination channel.

* | iwlwifi: mvm: disable beacon filtering during CSALuciano Coelho2014-11-24
| | | | | | | | | | | | | | | | | | After a channel switch, transmission on the new channel is only started once we see a beacon on it. Thus, beacon filtering needs to be disabled during channel switch so that mac80211 receives this beacon and finishes the process. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com>
* | iwlwifi: mvm: add a channel_switch op to bypass mac80211 timerLuciano Coelho2014-11-24
| | | | | | | | | | | | | | | | | | | | We need to call ieee80211_chswitch_done() ourselves just when the absence TE started, so we perform the actual context switch early enough. To do so, add a dummy channel_switch op, which will cause mac80211 to skip the countdown timer and allow us to call ieee80211_chswitch_done() to complete the operation.

* | iwlwifi: mvm: schedule CSA time event a bit before beacon 1Luciano Coelho2014-11-24
| | | | | | | | | | | | | | | | | | | | Instead of using a hardcoded number of TUs before beacon 0 as the time to start the absence and actual channel switch, calculate it in relation to the beacon interval. We use 10 TUs + beacon interval before beacon 0 to target a bit before beacon 1. This gives us enough time to switch to the new channel before the AP/GO switches.

| | | | | | | | | | | | | | | | | | | | | | Now that all CSA flows are using the switch_vif_chanctx op, we can rely on the switching_chanctx boolean that is passed to the __iwl_mvm_assign_vif_chanctx() and __iwl_mvm_unassign_vif_chanctx() functions to decide whether the context switch flows need to be executed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The spec requires to decrement the CSA counters based on TBTT, regardless if the beacon was actually transmitted. Previously, the fw would send beacon notifications only for successfully transmitted beacons. This behavior resulted in inaccurate CSA countdown. In order to address this issue, the fw was changed to send beacon notifications also for not transmitted beacons. Such notifications have TX_STATUS_INTERNAL_ABORT (0x92).
