* | BACKPORT: cfg80211: remove enum ieee80211_bandJohannes Berg2020-02-02
|/ | | | | | | | | | | | | | 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.

* iwlwifi: mvm: support using multiple ACs on single HW queueLiad Kaufman2015-10-05
| | | | | | | | | | | | | | | | | | | "DQA" is shorthand for "dynamic queue allocation", with the idea of allocating queues per-RA/TID on-demand rather than using shared queues statically allocated per vif. The goal of this is to enable future features (like GO PM) and to improve performance measurements of TX traffic. When RA/TID streams can't be neatly sorted into different AC queues, DQA allows sharing queues for the same RA. This means that DQA allows different ACs may reach the same HW queue. Update the code to allow such queue sharing by having a mapping between the HW queue and the mac80211 queues using it (as this could be more than one queue).

* iwlwifi: add wide firmware command infrastructure for TXAviya Erenfeld2015-08-04
| | | | | | | | | | | | | | | | | | | As the firmware is slowly running out of command IDs and grouping of commands is desirable anyway, the firmware is extending the command header from 4 bytes to 8 bytes to introduce a group (in place of the former flags field, since that's always 0 on commands and thus can be easily used to distinguish between the two. In order to support this most easily in the driver widen the command command ID used in the command sending functions and encode the new values (group and version) in the ID. That way existing code doesn't have to be changed (since the higher bits are 0 automatically) and newer code can easily use the new ID generation function to create a value to use in place of just the command ID.

* iwlwifi: remove command header flags fieldJohannes Berg2015-08-04
| | | | | | | | | | | | The 'flags' field really has been reserved in the firmware API for a very long time, probably since 4965. As a consequence, the field is always 0 and checking for a IWL_CMD_FAILED_MSK flag makes no sense. Rename the field to 'reserved', get rid of IWL_CMD_FAILED_MSK and all the code for it.

* iwlwifi: prepare for higher API/CAPA bitsJohannes Berg2015-06-03
| | | | | | | | | | | | | | | | | | Currently, loading the firmware fails when it has higher API or CAPA bits than the driver supports. That's an issue with integration. At the same time, actually using api[0] and capa[0] will become confusing when we also have api[1] and capa[1], and it's almost certain that we'll mix up the bits and use the bits for api[1] with api[0] by accident. Avoid all this by translating the API/CAPA bits to the regular kernel test_bit() format, and also providing wrapper functions. Also use the __bitwise__ facility of sparse to check that we're testing the right one.

* iwlwifi: mvm: capture connection loss as part of MLME triggerEmmanuel Grumbach2015-04-02
| | | | | | | | | | | | The only other way to catch these would have been to monitor the Tx deauth event, but we can send a deauth when we roam. So it would have been tricky to make sure we capture the connection losses only. Define a separate trigger for the connection losses to make it easier to catch them.

* 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: remove update type argument from quota updateJohannes Berg2014-07-07
| | | | | | | | | | | | | | | | It turns out that adding the update type argument was pointless as quota update is never called from the add_interface() callback. Therefore, IWL_MVM_QUOTA_UPDATE_TYPE_NEW isn't actually needed and then only a "disabled_vif" argument is needed for the upcoming CSA work. Remove the whole enum iwl_mvm_quota_update_type and pass the right arguments (always NULL for disabled vif right now) to the function in all current call sites.

* iwlwifi: mvm: configure low latency dependent scan parametersAlexander Bondar2014-03-18
| | | | | | | | | | | | | | | | | | | | | | | | In case of system low latency configure passive scan to be fragmented. Set the following scan parameters for both immediate and scheduled scan: - passive scan fragment duration = 20ms - out-of-channel time = 70ms - suspend time = 105ms Restructure channel's active/passive dwell time configuration to better suit the above change. The idea is that under low latency traffic passive scan is fragmented, i.e. that dwell on a particular channel will be fragmented. Each fragment dwell time is 20ms and fragments period is 105ms. Skipping to next channel will be delayed by the same period (105ms). So suspend_time parameter describing both fragments and channels skipping periods is set to 105ms. This value is chosen so that overall passive scan duration will not be too long. Max_out_time in this case is set to 70ms, so for active scanning operating channel will be left for 70ms while for passive still for 20ms (fragment dwell).

* iwlwifi: mvm: send udev event upon firmware error to dump logsEmmanuel Grumbach2014-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the firmware asserts, the driver will dump the firmware state to an internal buffer. This buffer is kept aside until it is dumped through debugfs. Once an external application fetched the data, the buffer is freed and a new buffer can be allocated in case another assert occurs. A udev event is sent to trigger an external application. A simple rule like: DRIVER=="iwlwifi", ACTION=="change", RUN+="/sbin/dump_sram.sh" can fetch the data from debugfs. Here is my dump_sram.sh: phyname=$(basename ${DEVPATH}) date=$(date +%F_%H_%M) filename=/var/log/iwl-sram-${phyname}-${date}.bin cat /sys/kernel/debug/ieee80211/${phyname}/iwlwifi/iwlmvm/fw_error_dump > ${filename} The current SRAM size is 80KB so, currently: $ ls -lh iwl-sram-phy0-2014-03-16_13_14.bin -rw-r--r-- 1 emmanuel emmanuel 81K Mar 16 13:15 iwl-sram-phy0-2014-03-16_13_14.bin and after compression: $ ls -lh iwl-sram-phy0-2014-03-16_13_14.bin.xz -rw-r--r-- 1 emmanuel emmanuel 13K Mar 16 13:15 iwl-sram-phy0-2014-03-16_13_14.bin.xz Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
