2015-11-26iwlwifi: mvm: remove unnecessary check in iwl_mvm_is_d0i3_supported()Luca Coelho
The d0i3_mode element is never set to IWL_D0I3_OFF, so it's not necessary to check it in iwl_mvm_is_d0i3_supported(). Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-11-26iwlwifi: mvm: flush all used TX queues before suspendingLuca Coelho
There is a potential race condition when entering suspend with d0i3 in PCIe. If there is a frame queued just before we suspend, it won't complete and we will never clear the queue stuck timer. To solve this, call TX_PATH_FLUSH to flush all queues (except the command queue) as part of the d0i3 entry process. Add a new function that returns all the flushable queues.

2015-11-26iwlwifi: dump prph registers in a common place for all transportsGolan Ben-Ami
Currently the prph registers dump is in the transport layer, and each bus needs an additional dump implementation. Move the prph dump outside transport, and allow a common implementation for all of the buses. This is possible because prph base addresses are similar for all buses.

2015-11-26iwlwifi: export the _no_grab version of PRPH IO functionsGolan Ben-Ami
Expose _no_grab prph i/o functions that allow performing i/o outside the transport, without requiring grab and release NIC access for each operation. In addition, rename the functions so they reflect their non-grabbing behavior. This can be very useful for consecutive prph i/o operation that occur outside trans, such as fw dumps.

2015-11-26iwlwifi: mvm: drop low_latency_agg_frame_cnt_limitEyal Shapira
This was an old workaround for solving latency issues with certain Miracast adapters like ActionTec. However this isn't needed anymore and furthermore it hurts throughput in other use cases.

2015-11-26iwlwifi: mvm: remove stray nd_config elementLuca Coelho
When the netdetect debugfs entry was removed, the nd_config element was accidentally left in the iwl_mvm structure. Remove it.

2015-11-26iwlwifi: mvm: remove redundant d0i3 flag from the config structLuca Coelho
The d0i3 flag in the device configuration structure is redundant, because the same information can be determined by checking the firmware capability flag. Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-11-26iwlwifi: mvm: add trigger for firmware dump upon TDLS eventsGolan Ben-Ami
This will allow to catch different TDLS events and get the firmware data when they occur. Add empty TX_LATENCY trigger on the way to avoid mismatch with trees in which this trigger is implemented.

2015-11-26iwlwifi: mvm: use build-time assertion for fw trigger IDJohannes Berg
The firmware debug trigger ID is always a compile-time constant, so we can use a build-time assertion to validate that it is in fact a valid constant. To make that really guaranteed to work, convert this and the inline function iwl_fw_dbg_trigger_simple_stop() to macros.

2015-11-26iwlwifi: generalize d0i3_entry_timeout module parameterLuca Coelho
The PCIe transport will also need a d0i3_entry_timeout_ms parameter, so move the existing one from the slave transports to iwlwifi, so it can be reused. While at it, rename the parameter to something shorter, namely d0i3_entry_delay. Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2015-11-26iwlwifi: mvm: check FW's response for nvm access write cmdMatti Gottlieb
In case of using an external NVM file, the driver sends to the FW the different nvm sections. In the response of the cmd, the FW states the status of the writing of the chunk. Currently the value is not checked by the driver. Check FW's response for writing the nvm chunk in the NVM_ACCESS_CMD.

2015-11-26iwlwifi: mvm: ignore LMAC scan notifications when running UMAC scansLuca Coelho
If the firmware sends LMAC scan notifications while a UMAC scan is running, just WARN and ignore it, otherwise the scanning state gets messed up. Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-11-26iwlwifi: mvm: Enable MPLUT only on supported hwAvri Altman
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.

2015-11-26iwlwifi: mvm: Configure fragmented scan for scheduled scanAvraham Stern
Configure the FW to use fragmented scan when the traffic load is high or low latency traffic is on. This is useful for scans that are managed by the FW (e.g. scheduled scan). Signed-off-by: Avraham Stern <avraham.stern@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-11-26iwlwifi: trans: make various conversion macros inlinesJohannes Berg
Make the various conversion functions typesafe, so we don't accidentally try to call them with the wrong pointers and cast them to something that will crash. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-11-26iwlwifi: dvm: remove Kconfig defaultJohannes Berg
The split of iwlwifi into DVM and MVM was a long time ago now, so we can remove the "default IWLWIFI" that we had to keep all existing .config files with working defaults during the split. This is no longer necessary, practically nobody should now be upgrading a .config that's older than the split.

2015-11-26iwlwifi: add support for 12K Receive BuffersEmmanuel Grumbach
802.11ac allows A-MSDU that can be up to 12KB long. Since an entire A-MSDU needs to fit into one single Receive Buffer (RB), add support for big RBs. Since this adds lots of pressure to the memory manager and significantly increase the true_size of the RX buffers, don't enable this by default.

2015-11-26iwlwifi: nvm: fix up phy section when reading itJohannes Berg
This is a workaround to an OTP bug. In Series 8000 1x1, the OTP 0xA052 defines 2x2 antenna configuration. This workaround overrides the decision based on HW id and on MIMO disabled bit which is correct in the OTP and set to disabled. This fixes the previous workaround "force 1x1 antenna in Series 8000".
