| | * | ath10k: implement rx reorder supportMichal Kazior2015-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New firmware and firmware (qca6174 hw3.0+ and fw 266+) are capable of full aggregation rx reordering. If it's enabled then Rx is handled via a new, separate htt event. The rx ring behaviour is changed a little to support the new rx scheme. These changes shouldn't affect qca988x performance.

| | * | ath10k: prevent fw reg dump spamMichal Kazior2015-01-15

Due to some changes in power_up/reset sequences sometimes when fw crashed ath10k would print the dump more than once via hif_stop -> warm_reset -> wait_for_target_init, possibly with different values each. Prevent this by doing the explicit fw register dump only during power_up instead of wait_for_target_init.

These packets arrive only after the out-of-channel activity is complete, which can be in the order of several seconds. Since TDLS ch-sw has no dialog-token-like mechanism for distinguishing sessions, use the GP2 time of the incoming ch-switch response to discern validity. For this purpose record the GP2 time of an outgoing TDLS ch-sw request and compare to the Rx time of the ch-sw response. The methods works in practice since the GP2 time of FW-deferred Rx is accurate and contains the real Rx timestamp.

The periphery register and the alive notification from the firmware. We have a check in iwl_pcie_tx_start that ensures that they are the same. When we resume from WoWLAN, the firmware may have crashed for whatever reason. In that case, the whole device may be reset which means that the periphery register will hold a meaningless value. When we come to compare trans_pcie->scd_base_addr (which really holds the value we had when we loaded the WoWLAN firmware upon suspend) and the current value of the register, we don't see a match unsurprisingly. Trick the check to avoid a loud yet harmless WARN. Note that when the WoWLAN has crashed, we will see that in iwl_trans_pcie_d3_resume which will let the op_mode know. Once the op_mode is informed that the WowLAN firmware has crashed, it can't do much besides resetting the whole device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices have 31 TFD queues. Don't enable it yet since there are still issues with it, but at least prepare the code for it. There was a bug in the read pointer assignment, fix that. Also, move the inline functions to iwl-scd.h which is the right place. Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In certain testing scenarios we'd like to force a decision between STBC/BFER/SISO. In the normal scenario this decision is done by the FW. Enable this option vis debugfs.

The driver now tells the FW whether BFER and/or STBC are allowed but the FW will make the decision to use either or stick to SISO on its own. BFER is limited to a single remote peer. The driver takes care of ensuring this to the FW and prioritizes with which peer BFER will be used.
