* | iwlwifi: mvm: add framework for triggers for fw dumpEmmanuel Grumbach2015-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the time, the issues we want to debug with the firmware dump mechanism are transient. It is then very hard to stop the recording on time and get meaningful data. In order to solve this, I add here an infrastucture of triggers. The user will supply a list of triggers that will start / stop the recording. We have two types of triggers: start and stop. Start triggers can start a specific configuration. The stop triggers will be able to kick the collection of the data with the currently running configuration. These triggers are given to the driver by the .ucode file - just like the configuration. In the next patches, I'll add triggers in the code. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

* iwlwifi: mvm: enable watchdog on Tx queues for mvmEmmanuel Grumbach2015-02-01
| | | | | | | | | | | | | | | | This watchdog allows to monitor the transmit queues. When a queue doesn't progress for a too long time, a timer fires and then, debug data can be collected. This watchdog has never been enabled on dvm controlled devices, so don't enable it there. In order to have it running on mvm controlled devices, we need to fix a small issue in the transport layer: mvm controlled devices use the shadow registers optimization. In this case, the watchdog wasn't running at all, even if enabled by the module parameter. Fix that on the way.

* iwlwifi: make U-APSD default configurable at compile timeJohannes Berg2014-09-03
| | | | | | | | | | | | | | With a significant number of deployed APs, enabling uAPSD leads to the AP never using aggregation sessions (likely due to the complexities involved in handling uAPSD in those.) This obviously results in a large drop in throughput with such APs. On the other hand, uAPSD can result in some power consumption benefits, but for now just disable it to get performance with affected APs back up.
