2016-10-19iwlwifi: mvm: fix netdetect starting/stopping for unified imagesLuca Coelho2-6/+46
With unified images, we need to make sure the net-detect scan is stopped after resuming, since we don't restart the FW. Also, we need to make sure we check if there are enough scan slots available to run it, as we do with other scans. Fixes: commit 23ae61282b88 ("iwlwifi: mvm: Do not switch to D3 image on suspend") Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-10-19iwlwifi: pcie: fix SPLC structure parsingLuca Coelho1-31/+48
The SPLC data parsing is too restrictive and was not trying find the correct element for WiFi. This causes problems with some BIOSes where the SPLC method exists, but doesn't have a WiFi entry on the first element of the list. The domain type values are also incorrect according to the specification. Fix this by complying with the actual specification. Additionally, replace all occurrences of SPLX to SPLC, since SPLX is only a structure internal to the ACPI tables, and may not even exist. Fixes: bcb079a14d75 ("iwlwifi: pcie: retrieve and parse ACPI power limitations") Reported-by: Chris Rorvick <chris@rorvick.com> Tested-by: Paul Bolle <pebolle@tiscali.nl> Tested-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-10-19iwlwifi: mvm: wake the wait queue when the RX sync counter is zeroSara Sharon4-3/+5
When we sync the RX queues the driver waits to receive echo notification on all the RX queues. The wait queue is set with timeout until all queues have received the notification. However, iwl_mvm_rx_queue_notif() never woke up the wait queue, with the result of the counter value being checked only when the timeout expired. This may cause a latency of up to 1 second.

2016-10-19iwlwifi: mvm: comply with fw_restart mod param on suspendHaim Dreyfuss1-1/+4
If the suspend flow fails, we restart the hardware to go back to the D0 image (with non-unified images), but we don't comply with the fw_restart module parameter. If something goes wrong when starting the D3 image, we may want to debug it, so we should comply with the fw_restart flag to avoid clearing everything up and losing the firmware state when the error occurred.

2016-10-19iwlwifi: mvm: fix d3_test with unified D0/D3 imagesLuca Coelho1-10/+15
When a unified D0/D3 image is used, we don't restart the FW in the D0->D3->D0 transitions. Therefore, the d3_test functionality should not call ieee8021_restart_hw() when the resuming either. Fixes: commit 23ae61282b88 ("iwlwifi: mvm: Do not switch to D3 image on suspend") Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-10-19iwlwifi: mvm: use ssize_t for len in iwl_debugfs_mem_read()Luca Coelho1-2/+2
In iwl_dbgfs_mem_read(), the len variable may become negative and is compared to < 0 (an error case). Comparing size_t (which is unsigned) to < 0 causes a warning on certain platforms (like i386): drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c:1561:5-8: WARNING: Unsigned expression compared with zero: len < 0 To prevent that, use ssize_t for len instead.

2016-10-19iwlwifi: pcie: mark command queue lock with separate lockdep classJohannes Berg1-0/+8
Emmanuel reports that when CMD_WANT_ASYNC_CALLBACK is used by mvm, the callback will be called with the command queue lock held, and mvm will try to stop all (other) TX queues, which acquires their locks - this caused a false lockdep recursive locking report. Suppress this report by marking the command queue lock with a new, separate, lock class so lockdep can tell the difference between the two types of queues.

The various TFD/TB helpers have two code paths depending on the type of TFD supported, with variable shadowing due to the new if branches.

2016-09-19iwlwifi: mvm: Add mem debugfs entryIdo Yariv2-0/+179
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>
2016-09-19iwlwifi: mvm: move AP-specific code to right functionJohannes Berg1-22/+20
There's no need for the common MAC context function to have an if on AP mode, the values can be overridden in the AP-specific function later.

There was recently a Full AP mode feature added where hostap adds the station at auth stage, and not assoc.
