2016-07-06iwlwifi: mvm: silence uninitialized variable warningDan Carpenter1-0/+2
"max_amsdu_len" isn't set if kstrtouint() fails. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-05-10iwlwifi: mvm: add a new mvm reference type for RX dataLuca Coelho1-0/+1
When a data packet is received, we need to make sure that we stay awake until it can be processed and wait a while before trying to enter runtime_suspend os system_suspend again. To do so, add a new reference type for RX data and take the reference when sending the packet to mac80211. We only do this for data packets, all the other RX packets sent by the firmware (e.g. notifications) are not a reason to prevent suspend. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-05-10iwlwifi: wake from runtime suspend before sending sync commandsLuca Coelho1-0/+1
If a host command was queued while in runtime suspend, it would go out before the D0I3_END_CMD was sent. Sometimes it works, but sometimes it fails, and it is obviously the wrong thing to do. To fix this, have the opmode take a reference before sending a SYNC command and make the pcie trans wait for the runtime state to become active before actually queueing the command.

2016-03-30iwlwifi: mvm: improve RSS configurationSara Sharon1-1/+4
Improve current RSS configuration: * Use netdev_rss_key instead of keeping a local copy. * Configure also UDP hashing to have UDP traffic spread across queues. * Do not direct RSS traffic to our fallback queue.

2016-03-30iwlwifi: remove support for fw older than -16.ucodeSara Sharon1-137/+27
API version lower than 16 is not supported anymore - don't load older ucode. Remove code handling older versions. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2016-03-09iwlwifi: mvm: add ctdp operations to debugfsChaya Rachel Ivgi1-0/+42
Add debugfs entries to get the ctdp budget average and to stop ctdp. Signed-off-by: Chaya Rachel Ivgi <chaya.rachel.ivgi@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2016-02-27iwlwifi: mvm: allow to limit the A-MSDU from debugfsEmmanuel Grumbach1-0/+19
in order to be able to tune the size of the desired A-MSDU based on link condition, add a knob to modify the length of the A-MSDU. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2016-02-27iwlwifi: mvm: fix RSS key sizingSara Sharon1-2/+3
The initialization and copying of the RSS secret key should not use ARRAY_SIZE as we need to initialize a dword array, and not a byte array. Fix also the hook maximum write size to allow writing a longer table - up to full indirection table size.

2016-02-01iwlwifi: mvm: allow to disable beacon filtering for AP/GO interfaceAndrei Otcheretianski1-0/+3
When in AP mode we need to filter in beacons from other APs to update HT operation mode. As a power optimization the beacons are filtered out when there are no associated stations. As a result, when there are no associated stations, we will not update the HT operation mode until a station connects. Add a debugfs parameter that allows to disable this optimization.

2016-02-01iwlwifi: mvm: support rss queues configuration commandSara Sharon1-0/+44
9000 series supports multi-queue rx. The hardware needs to be configured with the hash functions to perform and indirection table that maps hash results to the relevant CPUs\queues. Support this configuration. Add debugfs hook to configure the indirection table in order to enable performance analysis. The configuration is stateless, receives a partial or full pattern and sends the command to the firmware.

2016-02-01iwlwifi: mvm: add support for negative temperaturesChaya Rachel Ivgi1-4/+5
The driver should support also negative temperatures. So there is a need to separate between the return value and temperature in order to be able to distinguish between a negative temperature and error value.

2016-02-01iwlwifi: mvm: fix debugfs signedness warningJohannes Berg1-1/+1
Using kstrtouint() with a signed int isn't really right, use kstrotoint() instead. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-12-20iwlwifi: mvm: support description for user triggered fw dbg collectionGolan Ben-Ami1-2/+3
Add to the user triggered fw debug collection support for describing the reason of the trigger. This could be useful for identifying a dump by a unique id, passed as a description. Signed-off-by: Golan Ben-Ami <golan.ben.ami@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-12-20iwlwifi: change the Intel Wireless email addressEmmanuel Grumbach1-1/+1
ilw@linux.intel.com is not available anymore. linuxwifi@intel.com should be used instead. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-12-13iwlwifi: avoid d0i3 commands when no/init ucode is loadedEliad Peller1-0/+1
d0i3 commands are not supported in the init image, so take a reference to ensure we don't enter d0i3 during init image, and additional checks to prevent d0i3 commands when no fw image is loaded. Add a few WARN_ON_ONCE to the d0i3 enter/exit commands to ensure we send d0i3 commands only when the normal ucode is loaded.

2015-12-01iwlwifi: mvm: Support setting continuous recording debug modeGolan Ben Ami1-0/+40
Add ability to set the continuous recording mode of the FW, while the FW debug data is configured to be stored on the NIC. This could be useful for storing large segments of FW usniffer debug data on the host, while having small store space on the NIC. The host receives the usniffer data through the regular RX path, and the data can get extracted using trace-cmd.

2015-12-01iwlwifi: mvm: move fw-dbg code to separate fileGolan Ben-Ami1-0/+1

2015-11-26iwlwifi: mvm: drop low_latency_agg_frame_cnt_limitEyal Shapira1-4/+0
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.
