      iwlwifi: DMA fixes · df833b1d
      Reinette Chatre authored
      A few issues wrt DMA were uncovered when using the driver with swiotlb.
      - driver should not use memory after it has been mapped
      - iwl3945's RX queue management cannot use all of iwlagn because
        the size of the RX buffer is different. Revert back to using
        iwl3945 specific routines that map/unmap memory.
      - no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single,
        we can just call pci_unmap_single initially
      - only map the memory area that will be used by device. this is especially
        relevant to the mapping of iwl_cmd. we should not map the entire
        structure because the meta data at the beginning of structure contains
        the address to be used later for unmapping. If the address to be used for
        unmapping is stored in mapped data it creates a problem.
      - ensure that _if_ memory needs to be modified after it is mapped that we
        call _sync_single_for_cpu first, and then release it back to device with
      - we mapped the wrong length of data for host commands, with mapped length
        differing with length provided to device, fix that.
      Thanks to Jason Andryuk <jandryuk@gmail.com> for significant bisecting
      help to find these issues.

      mac80211/iwlwifi: move virtual A-MDPU queue bookkeeping to iwlwifi · e4e72fb4
      Johannes Berg authored
      This patch removes all the virtual A-MPDU-queue bookkeeping from
      mac80211. Curiously, iwlwifi already does its own bookkeeping, so
      it doesn't require much changes except where it needs to handle
      starting and stopping the queues in mac80211.
      To handle the queue stop/wake properly, we rewrite the software
      queue number for aggregation frames and internally to iwlwifi keep
      track of the queues that map into the same AC queue, and only talk
      to mac80211 about the AC queue. The implementation requires calling
      two new functions, iwl_stop_queue and iwl_wake_queue instead of the
      mac80211 counterparts.

      iwlwifi: Fix and rework Kconfig file · 80bc5393
      Reinette Chatre authored
      - iwlwifi is an optional driver and should thus not default to 'y'.
      - 3945 now depends on IWLCORE.
      - There is not a case when IWLCORE should not be selected. At the same time
        the driver does not use IWLWIFI or IWLCORE. We can just merge the usage of
        these two. With IWLWIFI being the driver name we proceed to use just it and
        replace instances of IWLCORE with it. The module name does not change
        and is still iwlcore.
      - Both IWLAGN and IWL3945 are selecting FW_LOADER, we can thus just move
        this up to one select when IWLWIFI is selected.
      - IWL5000 now supports Intel Wireless Wifi 100, 6000, and 6050 series.
      - Now that 3945 depends on IWLWIFI we can also indicate its dependency on
        MAC80211_LEDS and LEDS_CLASS at this level.
      - IWLAGN_LEDS is not used by driver - remove it.
      - IWLAGN_SPECTRUM_MEASUREMENT actually depends on IWLWIFI as it forms part
        of iwlcore module. Move this config up in Kconfig to reflect that and also
        change name to IWLWIFI_SPECTRUM_MEASUREMENT.
      - CONFIG_IWLWIFI_RFKILL is used by iwlagn as well as iwl3945, add text to
        description that indicates this.
      - CONFIG_IWL3945_RFKILL does not exist - remove usage from driver.
      - Add "iwlagn" to end of description of IWLAGN to help people understand
        what iwlagn means in rest of Kconfig text.
      - Add "iwl3945" to end of description of IWL3945 to help people understand
        what iwlagn means in rest of Kconfig text.
      - Change IWLWIFI_DEBUGFS description to indicate that only iwlagn supports
        it (for now).
