2021-02-05iwlwifi: mvm: remove debugfs injection limitationsJohannes Berg1-19/+7
For testing features where the firmware may send some notifications it can often be a lot easier to do that from a test script. Remove most injection limitations from debugfs to be able to do this.

2020-05-08iwlwifi: avoid debug max amsdu config overwriting itselfMordechay Goodstein1-4/+7
If we set amsdu_len one after another the second one overwrites the orig_amsdu_len so allow only moving from debug to non debug state. Also the TLC update check was wrong: it was checking that also the orig is smaller then the new updated size, which is not the case in debug amsdu mode.

2020-03-27iwlwifi: mvm: remove newline from rs_pretty_print_rate()Johannes Berg1-0/+4
Some of the places using this want the newline, but not all, so remove the newline from it and generate it in the debugfs files where it's desired. The effect of this is not printing double newlines in debug log messages.

2020-01-04iwlwifi: add device name to device_infoLuca Coelho1-1/+1
We have a lot of mostly duplicated data structures that are repeated only because the device name string is different. To avoid this, move the string from the cfg to the trans structure and add it independently from the rest of the configuration to the PCI mapping tables.

2019-11-15iwlwifi: remove IWL_DEVICE_22560/IWL_DEVICE_FAMILY_22560Johannes Berg1-1/+1
This is dead code, nothing uses the IWL_DEVICE_22560 macro and thus nothing every uses IWL_DEVICE_FAMILY_22560. Remove it all.

2019-11-15iwlwifi: mvm: don't skip mgmt tid when flushing all tidsHaim Dreyfuss1-1/+2
There are various of flows which require tids flushing (disconnection, suspend, etc...). Currently, when the driver instructs the FW to flush he masks all the data tids(0-7). However, the driver doesn't set the management tid (#15) which cause the FW not to flush it. When the FW tries to remove the mgmt queue he throws an assert since it is not an empty queue. instead of just set only the data tids set everything and let the FW ignore the invalid tids.

2019-09-06iwlwifi: add a pointer to the trans_cfg directly in transLuca Coelho1-2/+2
Add a pointer to the iwl_trans structure and point it to the trans part of the cfg. This is the first step in disassociating the trans configuration from the rest of the configuration. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-09-06iwlwifi: separate elements from cfg that are needed by trans_allocLuca Coelho1-3/+3
In order to be able to select the cfg depending on the HW revision or on the RF ID, we need to set up the trans before selecting the cfg. To do so, move the elements from cfg that are needed by iwl_trans_alloc() to a separate struct at the top of the cfg, so it can be used by other cfg types as well, before selecting the rest of the configuration.

2019-09-06iwlwifi: LTR updatesAlex Malamud1-0/+37
New FW versions introduces LTR feature enablement by default. For such FW versions, driver (mvm/xvt) should not send host command to enable LTR feature, also it should be possible to override LTR configuration through the debugfs. 1. Send LTR feature enablement command only for FW versions which does not advertises SET_LTR_GEN2 capability. 2. Implement ltr_config file in debugfs for LTR configuration override.

This debugfs file is really old, and cannot work properly since the unified image support. Rather than trying to make it work, which is difficult now due to multiple images (LMAC/UMAC etc.) just remove it - we no longer need it since we properly do a FW coredump even in D3 cases.

2019-01-29iwlwifi: mvm: include configured sniffer AID in radiotapJohannes Berg1-1/+43
In order to make more sense out of the captured radiotap data e.g. when the configured AID changes, add the currently configured AID to the radiotap data as a vendor extension field. This is made race-free by updating the included value from inside the RX path (using a notification wait) for the command response from the firmware, which thus means it's serialized with frame RX.

2019-01-29iwlwifi: mvm: implement CSI reportingJohannes Berg1-0/+1
Implement CSI (channel estimation matrix) reporting in the mvm driver, if the firmware has the capability. Currently only a debugfs API is provided as the API is still under discussion. For now, RX aggregation must be disabled to use this feature on data frames as we haven't found a good way to attach the data to A-MPDUs, given complexities with multi-queue.

2019-01-29iwlwifi: mvm: clean up LDBG config command usageJohannes Berg1-43/+0
Clean up the LDBG config command to not be called "continuous recording", and while at it actually remove the continuous recording implementation completely since it was only used for store & forward architectures. This also fixes a bug at least in iwl_fw_dbg_buffer_allocation() because what's now "__le32 type" (matching the firmware) used to be "__le16 enable_recording", so the buffer allocation config sub-struct would erroneously have started at the wrong offset. In the other cases this didn't actually lead to a bug as other bytes in pad[] were all zeroes, so accessing the 16-bit value as a 32-bit value wouldn't make a difference (in little endian.)

2018-03-02iwlwifi: avoid collecting firmware dump if not loadedShaul Triebitz1-3/+2
Trying to collect firmware debug data while firmware is not loaded causes various errors (e.g. failing NIC access). This causes even a bigger issue if at that time the HW radio is off. In that case, when later turning the radio on, the Driver fails to read the HW (registers contain garbage values). (It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN bit is cleared on faulty NIC access - since the same behavior was seen in HW RFKILL toggling before setting that bit.)
