2017-04-19iwlwifi: pcie: introduce new stop_deviceSara Sharon
This function is basically the same as gen1, except for clean ups of old devices configuration that are never used in a000 configuration. It will also help with refactoring rf_kill later on. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-04-19iwlwifi: pcie: prepare for dynamic queue allocationSara Sharon
In a000 transport we will allocate queues dynamically. Right now queue are allocated as one big chunk of memory and accessed as such. The dynamic allocation of the queues will require accessing the queues as pointers. In order to keep simplicity of pre-a000 tx queues handling, keep allocating and freeing the memory in the same style, but move to access the queues in the various functions as individual pointers. Dynamic allocation for the a000 devices will be in a separate patch. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-04-19iwlwifi: mvm: tell the firmware about the U-APSD parametersEmmanuel Grumbach
Newer firmware versions will be able to handle all the WMM-PS flows internally when we act as a GO. The firwmare relies on the fact that the drivers puts frames for different peers in different queues (DQA) to achieve this. The driver will not be aware of the power state of the peers anymore. Tell the firmware about the WMM-PS parameters of earch peer that connects to us so that it can know what are the trigger-enabled ACs, the delivery-enableds ACs and the Service Period length. This API change is backward compatible since older firmware versions will simply ignore the newly added values. Since we don't support ieee80211 TSPECs for now, just copy the trigger-enabled ACs to the delivery enabled ones.

2017-04-19iwlwifi: mvm: support a000 SCD queue configurationSara Sharon
a000 devices queue management is going to change significantly. We will have 512 queues. Those queues will be assigned number by the firmware and not by the driver. In addition, due to SN offload having TX queue shared between TIDs is impossible Also, the ADD_STA command no longer updates queues status. The only point of changing queue in the SCD queue config API. From driver perspective we have here a new design: Queue sharing and inactivity checks are disabled. Once this is done, the only paths that call scd_queue_cfg command are paths that alloc and release TX queues - which will make future accommodation to queue number assignment by FW easier. Since allocating 512 queues statically is not advisable, transport will allocate the queue on demand, fill the command with DRAM data and send it. This is reflected in the new transport API.

2017-04-19iwlwifi: pcie: introduce a000 TX queues managementSara Sharon
In a000 devices the TX handling is different in a few ways: * Queues are allocated dynamically * DQA is enabled by default * Driver shouldn't access TFH registers - ucode configures it all in SCD_QUEUE_CFG command Support all this in a new API with op mode, where op mode sends the command, transport will allocate the queue dynamically, fill in DMA properties, send the command to FW and get the ID back. Current implementation only sets the new transport API and fills the DMA properties. Future patches will complete the other parts.

2017-04-19iwlwifi: mvm: add support for EWRD (Dynamic SAR) ACPI tableLuca Coelho
Dynamic SAR allows changing TX power limits at runtime to comply with SAR regulations on multiple form factors (e.g. tablet vs. clamshell mode). To support this, a new table was added to ACPI, which is called Extended Wireless Regulatory Descriptor (EWRD). This table allows OEMs to define different TX power profiles for each form-factor or usage mode. Read this new table and store it in our SAR profiles table, in preparation for Dynamic SAR support.

2017-04-19iwlwifi: mvm: refactor SAR init to prepare for dynamic SARHaim Dreyfuss
We are adding support for dynamic TX power tables for SAR (specific absorption rate) compliance. Currently, we only support a single (static) TX power table, which is read from ACPI, and use it statically.

2017-04-19iwlwifi: mvm: add queues after adding stationSara Sharon
Currently aux & broadcast queues are added before calling add station, which results with a SCD_QUEUE_CFG command sent with a station id unknown yet to fw. While this works for pre-a000 firmware, the a000 fw requires the order to be reversed. The reason the change is only for a000 devices and not for previous devices is that we cannot reverse the order since the tfd_queue_mask containing the aux queue will cause FW to assert on adding a queue mask with a queue that is not enabled. This is not a problem in a000 fw since the tfd_queue_mask was removed from the add sta API. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-04-19ath: Fix updating radar flags for coutry code IndiaMohammed Shafi Shajakhan
As per latest regulatory update for India, channel 52, 56, 60, 64 is no longer restricted to DFS. Enabling DFS/no infra flags in driver results in applying all DFS related restrictions (like doing CAC etc before this channel moves to 'available state') for these channels even though the country code is programmed as 'India' in he hardware, fix this by relaxing the frequency range while applying RADAR flags only if the country code is programmed to India. If the frequency range needs to modified based on different country code, ath_is_radar_freq can be extended/modified dynamically.

2017-04-19ath9k: add noise floor override optionSimon Wunderlich
Introduce a debugfs option to manually override the noise floor, ignoring the automatically tuned noise floor of the driver/hw. In my tests with a AR9580 based module and a tx99 5 MHz interferer, I could tune the noisefloor to -95 dBm or above to allow communication again. The automatic noise floor calibration sometimes could adapt to the situation as well, but not reliably and permanently.

2017-04-19ath10k: fix spectral scan for QCA99X0 family of chipsetsMohammed Shafi Shajakhan
spectral_bin length (number of bins per fft sample) is usually a value where (2^n = value), n is an integer. All of the QCA99X0 family of chipsets seems to report a spectral_bin length of 2^n + 'm' bytes, where m = 4, 12 based on the chipset. This 'm' bytes seems to carry some radar related info which is currently discarded only for 'bin_len = 68' bytes. Extend this discarding of irrelevant 'bin_len' for QCA9984, QCA9888, IPQ4019 as well by introducing a hardware parameter 'spectral_bin_discard'. Also for QCA988X based family of chipsets which doesn't seem to have this issue and also for some of the hardware which I have not tested like QCA6174/QCA9377 the existing behaviour is retained as it is.

2017-04-18sh_eth: unmap DMA buffers when freeing ringsSergei Shtylyov
The DMA API debugging (when enabled) causes: WARNING: CPU: 0 PID: 1445 at lib/dma-debug.c:519 add_dma_entry+0xe0/0x12c DMA-API: exceeded 7 overlapping mappings of cacheline 0x01b2974d to be printed after repeated initialization of the Ether device, e.g. suspend/resume or 'ifconfig' up/down. This is because DMA buffers mapped using dma_map_single() in sh_eth_ring_format() and sh_eth_start_xmit() are never unmapped. Resolve this problem by unmapping the buffers when freeing the descriptor rings; in order to do it right, we'd have to add an extra parameter to sh_eth_txfree() (we rename this function to sh_eth_tx_free(), while at it).

2017-04-18ixgbe: Add support for maximum headroom when using build_skbAlexander Duyck
This patch increases the headroom allocated when using build_skb on a system with 4K pages. Specifically the breakdown of headroom versus cache size is as follows: L1 Cache Size Headroom 64 192 64, NET_IP_ALIGN == 2 194 128 128 128, NET_IP_ALIGN == 2 130 256 512 256, NET_IP_ALIGN == 2 258 I stopped at supporting only a cache line size of 256 as that was the largest cache size I could find supported in the kernel. With this we are guaranteeing at least 128 bytes of headroom to spare in the frame. This should be enough for us to insert a couple of IPv6 headers if needed which is likely enough room for anything XDP should need. I'm leaving the padding for systems with pages larger than 4K unmodified for now. XDP currently isn't really setup to work on those types of systems so we can cross that bridge when we get there.
