2015-03-12iwlwifi: mvm: fix force NMI for 8000Emmanuel Grumbach
The newer devices will enable a new register for this (DEVICE_SET_NMI_8000B_REG), but the interrupt handler isn't wired yet. Keep the old register for now. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-03-12iwlwifi: mvm: freeze the non-shared queues when a station goes to sleepEmmanuel Grumbach
When a station goes to sleep, we can't transmit any frame to it. This means that until that station will wake up, a queue that is dedicated to this station won't progress at all. Take this into account when monitoring stuck queues and don't account for the time the station was asleep. This allows to mask false positives where the queues are stuck not because of a bug, but because of the station being asleep. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-03-12iwlwifi: pcie: allow the op_mode to freeze the stuck queue timerEmmanuel Grumbach
This allows the op_mode to let the transport know that a queue is currently frozen and that its timer should be stopped. When the queue is unfrozen, its timer should be set to expire after the remainder of the timeout has elapsed. This can be used when stations go to sleep. When a station goes to sleep, the op_mode can freeze the timer so that the queue will never be considered as stuck. When the station wakes up, the queue will be unfrozen. This is meant to avoid false positives that would happen if a buggy station goes to sleep for a very long time. In case we have a dedicated queue for this station (BA agreement) and it goes to sleep for a very long time, the queue would rightfully be stopped during all that time. In this case, the stuck queue timer could fire and that would be a false positive. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2015-03-12iwlwifi: mvm: reflect TDLS pm state in mvmvif->pm_enabledArik Nemtsov
When entering D0i3, the MVM mutex cannot be grabbed. This interferes with the calculation of the number of connected TDLS stations during the setup of the power cmd. The goal is to disable power saving for all vifs while any TDLS station is connected. For this purpose it is enough to keep the pm_enabled member of all mvmvifs as false. An update of the power state already occurs when a TDLS station is added/removed, so the values are correctly updated.

2015-03-12iwlwifi: pcie: speed up the Tx DMA stop flowEmmanuel Grumbach
We don't need to acquire MAC access for each access, it makes much more sense to keep the MAC access. This speeds up the Tx DMA stop flow significantly. Moreover, if one channel can't be stopped, stop the others but don't poll for them to avoid being stuck there for a long time. This solves a situation in which we were stuck in that flow for way too long with a spinlock held which led to a kernel panic.

2015-03-05iwlwifi: mvm: BT Coex - fix a NULL pointer exceptionEmmanuel Grumbach
The commit below introduced an unsafe dereference of mvmvif->phy_ctxt. It can be NULL even if we hold the mutex. We can be handling a BT Coex notification while the vif has already been unassigned. This can happen since the BT Coex notification is hanled asynchronuously: we can have started to handle the BT Coex notification trying to acquire the mutex while the unassign flow already got it. The BT Coex notification handling will wait for the mutext. I'll get it later, but then mvmvif->phy_ctxt will be NULL.
