| | | * | | iwlwifi: mvm: implement the BlockAck related debug triggersEmmanuel Grumbach2015-05-285-10/+200
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BlockAck sessions can have events that are interesting to debug. When we send or receive a BAR, it is may indicate that something bad is happening. Even more so when mac80211 tells us that a frame timed out in the reodering buffer. Add a few triggers for BlockAck session debugging. Allow per-TID debugging. Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

As usual, we have a lot of small fixes and cleanups, the bigger items are: * proper mac80211 rate control locking, to fix some random crashes (this required changing other locking as well) * mac80211 "fast-xmit", a mechanism to reduce, in most cases, the amount of code we execute while going from ndo_start_xmit() to the driver * this also clears the way for properly supporting S/G and checksum and segmentation offloads
| | | * | | | iwlwifi: mvm: treat scan races also on UMAC scansLuciano Coelho2015-05-281-10/+2

Now that UMAC and LMAC scans use the same state flags, we can also handle the race conditions for UMAC.

To make the flows cleaner and more balanced, combine the UMAC part into the main stop functions. This also makes us take one step closer into combining the state flags for both APIs. Note that some STOPPING flags will be dangling in UMAC scans, but it doesn't matter because they are not used in UMAC yet (and this will be fixed in subsequent patches).

However, all the products that currently require this don't have a need for the full randomisation. Therefore, advertise the feature anyway which results in host- based randomisation, done whenever the system suspends. This is sufficient for the platforms currently requiring this feature. If we ever extend this in the future to do full randomisation in the firmware, then certainly this will still be sufficient for the current requirements, so it doesn't make a lot of sense to split the feature bits.

While doing it, it moved the ROC reference release to a common work item, which is being called for both the ROC and aux ROC flows. This resulted in invalid reference accounting, as no reference was taken in case of aux ROC, while a reference was released on completion. Fix it by adding a reference for the aux ROC as well, and release only the relevant references on completion (according to the set bits). While at it, convert cancel_work_sync() to flush_work(), in order to make sure the references are being cleaned properly.

Doing this causes an NMI protection error (RT_NMI_INTERRUPT_PREG_PROTECTION). To fix this, skip those calls if the device family is IWL_DEVICE_FAMILY_8000.

It is a single stream bgn chip with no bells or whistles. This driver is partially based on Felix's mt76 but IMHO it doesn't make sense to merge the two right now because MT7601U is a design somewhere between old Ralink devices and new Mediatek chips. There wouldn't be all that much code sharing with the devices mt76 supports. Situation may obviously change when someone decides to extend m76 with support for the more recent USB dongles. The driver supports only station mode. I'm hoping to add AP support when time allows.
