2019-02-04iwlwifi: mvm: simplify some return conditionsSara Sharon1-5/+2
Simplify some return conditions found by running a semantic patch to detect unnecessary assignments to local variables. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2018-09-28iwlwifi: mvm: TLC support for Coex Schema 2Erel Geron1-0/+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 <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2018-08-31iwlwifi: remove all occurrences of the FSF address paragraphLuca Coelho1-5/+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 <[email protected]>
2018-08-31iwlwifi: mvm: support Coex Schema 2Erel Geron1-2/+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 <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2018-04-20iwlwifi: mvm: BT Coex - make the primary / secondary pick traffic awareEmmanuel Grumbach1-0/+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.

2017-11-25iwlwifi: mvm: revert support new Coex firmware APIEmmanuel Grumbach1-27/+6
This new API will not be used, remove the code that supports it. Signed-off-by: Emmanuel Grumbach <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-08-18iwlwifi: mvm: support new Coex firmware APIEmmanuel Grumbach1-6/+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 <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-08-18iwlwifi: mvm: remove the corunning supportEmmanuel Grumbach1-268/+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.

2017-08-09iwlwifi: mvm: fix the coex firmware APIEmmanuel Grumbach1-4/+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. Fixes: 430a3bbafdc7 ("iwlwifi: mvm: BT Coex - new API") Signed-off-by: Emmanuel Grumbach <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-08-01iwlwifi: reorganize firmware APIJohannes Berg1-1/+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.

2017-06-29iwlwifi: mvm: change when the BT_COEX is sentEmmanuel Grumbach1-1/+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 <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-06-02iwlwifi: mvm: document structures used by commandsJohannes Berg1-1/+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 <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-04-19iwlwifi: mvm: prepare for station count changeSara Sharon1-1/+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.

2016-07-06iwlwifi: mvm: fix the channel inhibition table for Channel 14Emmanuel Grumbach1-1/+1
The value for Channel 14 was wrong. Fix it. Signed-off-by: Emmanuel Grumbach <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2016-07-06iwlwifi: mvm: fix coex related commentsEmmanuel Grumbach1-2/+2
Those comments were wrong, fix them. Signed-off-by: Emmanuel Grumbach <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg1-5/+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 <[email protected]>
2016-03-30iwlwifi: remove support for fw older than -16.ucodeSara Sharon1-42/+0
API version lower than 16 is not supported anymore - don't load older ucode. Remove code handling older versions. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2015-12-20iwlwifi: change the Intel Wireless email addressEmmanuel Grumbach1-1/+1
[email protected] is not available anymore. [email protected] should be used instead. Signed-off-by: Emmanuel Grumbach <[email protected]>
2015-12-01iwlwifi: mvm: Align bt-coex priority with requirementsAvri Altman1-15/+21
Fix the gaps between the system requirements and our code. Signed-off-by: Avri Altman <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2015-11-26iwlwifi: mvm: Enable MPLUT only on supported hwAvri Altman1-4/+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.
