* | | iwlwifi: mvm: fix init_dbg flow to work as expectedLiad Kaufman2014-11-11
|/ / | | | | | | | | | | | | | | | | | | Even if running the driver with param init_dbg=1 - on INIT image error - iwl_trans_stop_device() was still called. This patch fixes that and calls iwl_trans_stop_device() on INIT image failure only if init_dbg=0.

* iwlwifi: mvm: prepare for scheduler config commandAvri Altman2014-09-16
| | | | | | | | | | | | | | | | | | | | The scheduler is a HW sub-block that directs the work of the Flow Handler by issuing requests for frame transfers, specifying source and destination. Its primary function is to allocate flows into the TX FIFOs based upon a pre-determined mapping. The driver has some responsibilities to the scheduler, namely initialising and maintaining the hardware registers. This is currently done by directly accessing them, which can cause races with the firmware also accessing the registers. To address this problem, change the driver to no longer directly access the registers but go through the firmware for this if the firmware has support for DQA and thus the new command.

* iwlwifi: mvm: use the firmware to get the temperature during CT killLuciano Coelho2014-09-14
| | | | | | | | | | | | | | | | Reading the temperature directly from the hardware, without the help of the firmware, is a complex process and is not entirely the same for different hardware. Also, some NICs don't easily allow access to the sensors when the firmware is not running, which would add even more complexity to the code. To reduce the code complexity and to avoid code duplication between the firmware and the driver, boot the firmware briefly to read the current temperature while in CT kill mode.

* iwlwifi: mvm: add Aux ROC request/response flowAriej Marjieh2014-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | The Remain On Channel framework added to the firmare is a bit like time events. It allows the driver to request the firmware to be on a certain channel for a certain time. Unlike the time events, the ROC infrastructure doesn't need a MAC context in the firmware - it uses a generic context called "auxiliary framework". This is useful for any offchannel activity that is not bound to a specific MAC. The flow is synchronized much like with time events: 1) The driver receives an action frame from the wpa_supplicant via nl80211 that requests to be sent offchannel. 2) The driver sends an Aux ROC command (0x53) to the firmware. 3) The firmware responds with the unique id of the time event. 4) When time event starts, the driver puts the frame in the Aux queue. Special care needs to be taken when the time events ends: the queue needs to be cleaned-up.
