2015-10-05iwlwifi: mvm: fix signedness warnings in ToF debugfsJohannes Berg1-6/+10
Using an int* instead of u32* as the kstrtou32() output argument obviously results in signedness warnings, change that. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

There's obviously no reason to write a NUL-terminating byte into the debugfs file. Apparently nobody tried to use this from a tool that doesn't strip NUL bytes though, so we never noticed. Fix it.

The &mvm->tof_data.range_req.ap[] array has IWL_MVM_TOF_MAX_APS elements so the check should be >= instead of >. Also the test can underflow so I have changed "i" to unsigned.

2015-08-04iwlwifi: mvm: add basic Time of Flight (802.11mc FTM) supportGregory Greenman1-0/+751
ToF is a time based method for measurement of the WiFi device location within a WiFi environment. The driver functionality provided by this patch is the interface for communication with FW and receiving location related updates from the FW. The interface provided by this patch is via debugfs.

2014-09-08iwlwiwi: mvm: use bss_conf->dtim_period instead of conf.ps_dtim_periodEmmanuel Grumbach1-2/+1
The latter is meant for software implementation of power save and is not per-virtual interface. Since our driver supports multiple virtual interfaces, we need to use vif->bss_conf.dtim_period. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2014-09-03iwlwifi: mvm: add use_ps-poll debugfs power optionEliad Peller1-0/+8
By default, when uapsd is not used, the ucode uses null data packet to exit power-save and get then pending frames. However, some tests require the explicit usage of ps-poll. Allow setting use_ps_poll power option (through debugfs) to configure the ucode to use ps-poll instead. The ucode configuration is done by setting the advanced-pm flag while setting all the ACs to non-upasd mode.

CMD_SYNC is really 0 which is confusing: if (cmd.flags & CMD_SYNC) is always false. Fix this by simply removing its definition. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2014-02-13iwlwifi: mvm: Enable power save on BSS and P2P client in DCMAlexander Bondar1-1/+1
New FW enables support for power save on BSS and P2P client MACs simultaneously when they function on different channels (DCM). Enable this case in the driver after examining new TLV flag - IWL_UCODE_TLV_FLAGS_BSS_P2P_PS_DCM. Still power management is not allowed on both MACs if they function on a same channel. Remove another redundant TLV flag - IWL_UCODE_TLV_FLAGS_P2P_PS that is not in use anymore. Remove bound_vif_cnt as redundant.

2014-02-04iwlwifi: mvm: refactor power codeEmmanuel Grumbach1-1/+1
The main complexity of the power code is that it needs to take into account the firmware limitations. These limitations state that we need to have a global picture of the vifs present in the system to be able to decide if we can enable power management on a specific vif. Even device power save (as opposed to vif power management) must be disabled in certain circumstances (monitor vif). Refactor the current code to make this clearer by defining a function that explicitely computes these constraints. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-02-04iwlwifi: mvm: remove support for legacy power APIEmmanuel Grumbach1-3/+4

2013-12-16iwlwifi: mvm: use pre-RCU-sync sta removal operationJohannes Berg1-5/+8
iwlmvm relies on the current mac80211 behaviour of allowing station pointers to be valid for an RCU grace period after returning from the sta_state() callback. To optimise these cases, this behaviour is going away, so make the driver use the new sta_pre_rcu_remove() method to clear the pointer in the fw_id_to_mac_id[] array. Since this may happen while the station is still present in the firmware, don't set the pointer to NULL but to -ENOENT to mark this particular case. In client mode, the station is kept even longer (until marking the MAC as unassociated) so the drain flow must take this new behavior into account.

2013-12-10iwlwifi: mvm: move interface-specific debugfs to a new fileJohannes Berg1-0/+190
The debugfs file is getting pretty large and mixed up between code for the hardware and code for each interface (the two aren't even clearly separated in the code). Make it easier to handle by splitting the per-interface code into a separate file called debugfs-vif.c.
