      b43: Fix throughput regression · b6c3f5be
      Larry Finger authored
      Commit c7ab5ef9
      
       entitled "b43: implement
      short slot and basic rate handling" reduced the transmit throughput for
      my BCM4311 device from 18 Mb/s to 0.7 Mb/s. The basic rate handling
      portion is OK, the problem is in the short slot handling.
      
      Prior to this change, the short slot enable/disable routines were never
      called. Experimentation showed that the critical part was changing the
      value at offset 0x0010 in the shared memory. This is supposed to contain
      the 802.11 Slot Time in usec, but if it is changed from its initial value
      of zero, performance is destroyed. On the other hand, changing the value
      in the MMIO register corresponding to the Interframe Slot Time increased
      performance from 18 to 22 Mb/s. A BCM4306/3 also shows dramatic
      improvement of the transmit rate from 5.3 to 19.0 Mb/s.
      
      Other changes in the patch include removal of the magic number for the
      MMIO register, and allowing the slot time to be set for any PHY operating
      in the 2.4 GHz band. Previously, the routine was executed only for G PHYs.

      b43: Dynamically control log verbosity · 060210f9
      Michael Buesch authored
      
      
      Dynamically control the log verbosity with a module parameter.
      This enables us to dynamically enable debugging messages (or disable
      info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose.
      
      This increases the module size by about 3k. But in practice it reduces the
      module size for the user, because some distributions ship the b43 module
      with CONFIG_B43_DEBUG set, which increases the module by about 15k.
      
      So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG.
      There is no reason to keep it in a production-release kernel.
      So we have a net reduction in size by about 12k.
      
      This patch also adds a printk of the wireless core revision, so people
      don't have to enable SSB debugging to get the wireless core revision.

      b43: Automatically probe for opensource firmware · 1a9f5093
      Michael Buesch authored
      
      
      First probe for proprietary firmware and then probe for opensource firmware.
      This way around it's a win-win situation.
      1) If proprietary fw is available, it will work.
      2) If opensource firmware is available, but no proprietary (Distros can only ship open fw)
         it might work.
      3) If both open and proprietary are available, it will work, because it selects
         the proprietary. We currently don't prefer the open fw in this case, because it doesn't
         work on all devices. It would introduce a regression otherwise.
      
      The remaining FIXMEs in this patch are harmless, because they only matter on multiband
      devices, which are not implemented yet anyway.

      b43: Rewrite TX power adjustment · 18c8adeb
      Michael Buesch authored
      
      
      This patch rewrites the TX power recalculation algorithms to scale better
      with changed enviromnent. If there's low
      TX traffic, the power will be checked against the desired values
      every 60 seconds.
      If there is high TX traffic, the check is redone every 2 seconds. This improves
      the reaction times a lot and confuses the rate control less.
      It will also reduce the time it initially takes to tune to a new TX power
      value. With the old algorithm it could take about 30 to 45 seconds to settle to
      a new power value. This will happen in about two to four seconds now.

      b43: Implement dynamic PHY API · ef1a628d
      Michael Buesch authored
      
      
      This patch implements a dynamic "ops" based PHY API.
      This is needed in order to conveniently support future PHY types
      to avoid the "switch"-hell.
      
      This patch does not change any functionality. It just moves lots
      of code from one place to another and adjusts it for the changed
      data structures.
