      iwlwifi: mvm: support using multiple ACs on single HW queue · 4ecafae9
      Liad Kaufman 提交于
      "DQA" is shorthand for "dynamic queue allocation", with the
      idea of allocating queues per-RA/TID on-demand rather than
      using shared queues statically allocated per vif. The goal
      of this is to enable future features (like GO PM) and to
      improve performance measurements of TX traffic.
      
      When RA/TID streams can't be neatly sorted into different AC
      queues, DQA allows sharing queues for the same RA. This means
      that DQA allows different ACs may reach the same HW queue.
      
      Update the code to allow such queue sharing by having a mapping
      between the HW queue and the mac80211 queues using it (as this
      could be more than one queue).

      iwlwifi: mvm: init card correctly on ctkill exit check · 1a3fe0b2
      Arik Nemtsov 提交于
      During the CT-kill exit flow, the card is powered up and partially
      initialized to check if the temperature is already low enough.
      Unfortunately the init bails early because the CT-kill flag is set.
      Make the code bail early only for HW RF-kill, as was intended by the
      author. CT-kill is self-imposed and is not really RF-kill.

      iwlwifi: mvm: Add FW paging mechanism for the UMAC on SDIO · e1120187
      Matti Gottlieb 提交于
      Family 8000 products has 2 embedded processors, the first
      known as LMAC (lower MAC) and implements the functionality from
      previous products, the second one is known as UMAC (upper MAC)
      and is used mainly for driver offloads as well as new features.
      The UMAC is typically “less” real-time than the LMAC and is used
      for higher level controls.
      The UMAC's code/data size is estimated to be in the mega-byte arena,
      taking into account the code it needs to replace in the driver and
      the set of new features.
      
      In order to allow the UMAC to execute code that is bigger than its code
      memory, we allow the UMAC embedded processor to page out code pages on
      DRAM.
      
      When the device is slave on the bus(SDIO) the driver saves the UMAC's
      image pages in blocks of 32K in the DRAM and sends the layout of the
      pages to the FW. When the FW wants load / unload pages, it creates an
      interrupt,	and the driver uploads / downloads the page to an address in
      the a specific address on the device's memory.
      
      The driver can support up to 1 MB of pages.
      
      Add paging mechanism for the UMAC on SDIO in order to allow the program to
      use a larger virtual space while using less physical memory on the device
      itself.

      iwlwifi: mvm: add the ability to trigger only monitor dumps · 36fb9017
      Oren Givon 提交于
      Change the FW debug trigger tlv to include a monitor only
      option. Setting this option to true will cause fw dump triggers
      to only collect monitor data and skip other dumps such as
      SMEM, SRAM, CSR, PRPH, etc.
      This option is used when accessing the different parts of the
      firmware memory is not wanted and can cause unwanted behavior
      like when debugging TX latency.

      iwlwifi: prepare for higher API/CAPA bits · 859d914c
      Johannes Berg 提交于
      Currently, loading the firmware fails when it has higher API or CAPA
      bits than the driver supports. That's an issue with integration.
      
      At the same time, actually using api[0] and capa[0] will become
      confusing when we also have api[1] and capa[1], and it's almost
      certain that we'll mix up the bits and use the bits for api[1] with
      api[0] by accident.
      
      Avoid all this by translating the API/CAPA bits to the regular kernel
      test_bit() format, and also providing wrapper functions. Also use the
      __bitwise__ facility of sparse to check that we're testing the right
      one.

      iwlwifi: mvm: don't power off the device between INIT and OPER firmwares · 8d193ca2
      Eran Harary 提交于
      Our device needs two different firmwares: the INIT firmware
      and the operational (OPER) firmware. The first one is run
      when the driver loads and it returns calibrations results
      as well as the NVM. The second one implements the WiFi
      protocol.
      
      If the wlan interface is not brought up, the device is put
      to low power state: no firmware will be running. When the
      interface is brought up, we would run the OPER firmware
      only and reuse the results of the run of the INIT firmware
      when the driver was loaded. This is changing with this
      patch.
      We now run the INIT firmware every time mac80211 calls
      start(). The penalty for that is minimal since the INIT
      firwmare run fast. I now also avoid to power down the device
      between the INIT and OPER firmware on certains buses.
      
      The motivation for this change is that there are components
      on the device (MFUART) that are triggered by the INIT
      firmware and need the device to be powered up in order to
      keep running. Powering the device down between the INIT and
      OPER firmware would stop these components and prevent them
      from running again since they are triggered by the INIT
      firmware only.
      The new flow allows this and also allows to trigger these
      components again when the interface is brought up after
      it has been brought down.

      iwlwifi: mvm: do string formatting in debug triggers · 5d4f929e
      Johannes Berg 提交于
      The current code has a lot of duplicates of printing into a buffer
      (while having to make sure it's NUL-filled and -terminated) and
      then passing that to the debug trigger collection.
      
      Since that's error-prone, instead make the debug trigger collection
      function take a format string and format arguments (with compiler
      validity checking) and handle the buffer internally.
      
      This makes one behavioural change -- instead of sending the whole
      buffer to userspace (clearing is needed to not leak stack data) it
      just passes the actual string (including NUL-terminator.)
