2017-08-18iwlwifi: move BT_MBOX_PRINT macro to common headerLuca Coelho
Move the BT_MBOX_PRINT() macro from mvm/debugfs.c to fw/api/coex.h so it can be reused and remove duplicate definition of BT_MBOX_MSG(), keeping only the one already in coex.h. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-08-18iwlwifi: mvm: remove the corunning supportEmmanuel Grumbach
The corunning block was supposed to help in coex scenarios. It required the driver to configure the firmware based on the coupling between the two antennas of the devices. This was never in use and the configuration sent by the driver has always been blank. Remove all that code.

2017-08-09iwlwifi: mvm: fix the coex firmware APIEmmanuel Grumbach
The firmware API defined in the header files didn't match the structure that are actually passed by the firmware. The impact could be a decision for MIMO in Tx or Rx in coex scenarios.

2017-08-09iwlwifi: mvm: add debugfs to force CT-killChaya Rachel Ivgi
CT-kill is a thermal-based "RF-kill", which disables the NIC completely if the temperature gets too high, in order to avoid damage. Add a debugfs entry to simulate high temperatures, in order to test CT-kill flows in the driver without having to physically heat the device up.

2017-06-29iwlwifi: create new subdirectory for FW interactionJohannes Berg
There's a lot of mvm code that really should be more generic and part of the iwlwifi module.

2017-06-29iwlwifi: unify external & internal modparam namesJohannes Berg

2017-06-29iwlwifi: mvm: change when the BT_COEX is sentEmmanuel Grumbach
The BT_COEX command should not be sent to the INIT firmware image starting from 8000 family. The firmware team also requested to send the BT_COEX command after the PHY_DB_CMD and the PHY_CFG_CMD.

2017-06-23iwlwifi: mvm: support new flush APIMordechai Goodstein

2017-06-05iwlwifi: mvm: check firmware is up in debugfsJohannes Berg
Protect various debugfs files that need to communicate with the firmware from being used when the firmware isn't running.

2017-04-19iwlwifi: mvm: prepare for station count changeSara Sharon
In a000 devices we will support up to 32 stations. The max station define is used also for invalid station marking which makes finding usages of actual maximum station pretty hard to sort through - change it to be a different define in order to make future changes easier. Use also ARRAY_SIZE intead of define when possible. Do not move yet to 32 stations until firmware do it though.

In iwl_dbgfs_mem_read(), the len variable may become negative and is compared to < 0 (an error case).

2016-09-19iwlwifi: mvm: Add mem debugfs entryIdo Yariv
In order to access cached/paged memory, there are a couple of firmware commands (one for UMAC and one for LMAC) that let the host access memory and registers indirectly. Since this is done by the firmware on behalf of the host, even if memory is paged out or cached, the host will retrieve the memory as the firmware sees it (paged out memory will get paged in). Export this mechanism via a debugfs entry for both read and write access. WARNING: This mechanism has no protections at all. Invalid addresses may crash or hang the firmware. Writing to arbitrary memory also comes with no guarantees. Signed-off-by: Ido Yariv <idox.yariv@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2016-05-10iwlwifi: mvm: add a new mvm reference type for RX dataLuca Coelho
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 Coelho
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.

2016-02-01iwlwifi: mvm: allow to disable beacon filtering for AP/GO interfaceAndrei Otcheretianski
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 Sharon

Support this configuration. Add debugfs hook to configure the indirection table in order to enable performance analysis.
