* iwlwifi: mvm: simplify some return conditionsSara Sharon2019-02-041-5/+2
| | | | | | | | Simplify some return conditions found by running a semantic patch to detect unnecessary assignments to local variables. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: mvm: TLC support for Coex Schema 2Erel Geron2018-09-281-0/+9
| | | | | | | | The new coex schema requires setting the non-shared antenna for the single_stream_ant_msk field in the TLC command. Signed-off-by: Erel Geron <erelx.geron@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: remove all occurrences of the FSF address paragraphLuca Coelho2018-08-311-5/+0
| | | | | | | | The Free Software Foundation address is superfluous and causes checkpatch to issue a warning when present. Remove all paragraphs with FSF's address to prevent that. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: mvm: support Coex Schema 2Erel Geron2018-08-311-2/+7
| | | | | | | | | The new coex schema requires moving to SISO only when BT AG is 4. Adjust the SISO criteria according to the coex schema version reported by firmware. Signed-off-by: Erel Geron <erelx.geron@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: mvm: BT Coex - make the primary / secondary pick traffic awareEmmanuel Grumbach2018-04-201-0/+37
| | | | | | | | | | | | | | | | The primary channel is the channel that will be untouched by BT. The secondary channel might be touched by BT. Hence, we want the primary to be the most active channel. To do so, use the TCM infrastructure. Since the BT keeps sending notifications, we can rely on them to trigger the check. Every 10 seconds, we will check what is the most active context and chose the right primary. We need to wait 10 seconds before we modify the settings because frequent changes in these settings can confuse BT.

* iwlwifi: mvm: support new Coex firmware APIEmmanuel Grumbach2017-08-181-6/+27
| | | | | | | | | | The firmware now adds more information about time sharing with the Bluetooth core. Adapt the API structures and add the new fields in the debugfs hooks. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: mvm: remove the corunning supportEmmanuel Grumbach2017-08-181-268/+0
| | | | | | | | | | | | The corunning block was supposed to help in coex scenarios. It required the driver to configure the firmware based on the coupling between the two antennas of the devices. This was never in use and the configuration sent by the driver has always been blank. Remove all that code.

* iwlwifi: mvm: fix the coex firmware APIEmmanuel Grumbach2017-08-091-4/+3
| | | | | | | | | | | The firmware API defined in the header files didn't match the structure that are actually passed by the firmware. The impact could be a decision for MIMO in Tx or Rx in coex scenarios.

* iwlwifi: reorganize firmware APIJohannes Berg2017-08-011-1/+1
| | | | | | | | | | | | | | Apart from DVM, all firmware uses the same base API, and there's code outside iwlmvm that needs to interact with it. Reflect this in the source better and reorganize the firmware API to a new fw/api/ directory. While at it, split the already pretty large fw-api.h file into a number of smaller files, going from almost 3k lines in there to a maximum number of lines less than 1k.

* iwlwifi: mvm: change when the BT_COEX is sentEmmanuel Grumbach2017-06-291-1/+1
| | | | | | | | | | | | | The BT_COEX command should not be sent to the INIT firmware image starting from 8000 family. The firmware team also requested to send the BT_COEX command after the PHY_DB_CMD and the PHY_CFG_CMD. While at it: s/iwl_send_bt_init_conf/iwl_mvm_send_bt_init_conf/ Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: mvm: document structures used by commandsJohannes Berg2017-06-021-1/+2
| | | | | | | | | Add documentation to a lot of command IDs that links to the appropriate structure(s) used with those IDs. In one case, actually add and use a new struct for that purpose. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: mvm: prepare for station count changeSara Sharon2017-04-191-1/+1
| | | | | | | | | | | | | In a000 devices we will support up to 32 stations. The max station define is used also for invalid station marking which makes finding usages of actual maximum station pretty hard to sort through - change it to be a different define in order to make future changes easier. Use also ARRAY_SIZE intead of define when possible. Do not move yet to 32 stations until firmware do it though.

* cfg80211: remove enum ieee80211_bandJohannes Berg2016-04-121-5/+5
| | | | | | | | | This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* iwlwifi: mvm: Enable MPLUT only on supported hwAvri Altman2015-11-261-4/+1
| | | | | | | | | | | | | | When there's a bt-wifi contention that requires arbitration, we use a priority-based mechanism to decide which comm wins. Over time, use cases become more and more complex, with multiple concurrent active links with different traffic types and different QoS requirements, on both WiFi and BT sides. This, in turn, requires us to elaborate our prioritization mechanism. However, our legacy products included hw that does not supports this, so selectively enable this on specific hw - as signaled by the firmware.
