      b43: Rewrite TX power adjustment · 18c8adeb
      由 Michael Buesch 提交于 
      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
      由 Michael Buesch 提交于 
      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.

      mac80211: use hardware flags for signal/noise units · 566bfe5a
      由 Bruno Randolf 提交于 
      trying to clean up the signal/noise code. the previous code in mac80211 had
confusing names for the related variables, did not have much definition of
what units of signal and noise were provided and used implicit mechanisms from
the wireless extensions.

this patch introduces hardware capability flags to let the hardware specify
clearly if it can provide signal and noise level values and which units it can
provide. this also anticipates possible new units like RCPI in the future.

for signal:

  IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
  IEEE80211_HW_SIGNAL_DB     - dB difference to unspecified reference point
  IEEE80211_HW_SIGNAL_DBM    - dBm, difference to 1mW

for noise we currently only have dBm:

  IEEE80211_HW_NOISE_DBM     - dBm, difference to 1mW

if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
to provide the maximum value (max_signal) it reports in order for applications
to make sense of the signal values.

i tried my best to find out for each driver what it can provide and update it
but i'm not sure (?) for some of them and used the more conservative guess in
doubt. this can be fixed easily after this patch has been merged by changing
the hardware flags of the driver.

      mac80211: QoS related cleanups · e100bb64
      由 Johannes Berg 提交于 
      This
 * makes the queue number passed to drivers a u16
   (as it will be with skb_get_queue_mapping)
 * removes the useless queue number defines
 * splits hw->queues into hw->queues/ampdu_queues
 * removes the debugfs files for per-queue counters
 * removes some dead QoS code
 * removes the beacon queue configuration for IBSS
   so that the drivers now never get a queue number
   bigger than (hw->queues + hw->ampdu_queues - 1)
   for tx and only in the range 0..hw->queues-1 for
   conf_tx.

      b43: Don't disable IRQs in mac_suspend · e40ac414
      由 Michael Buesch 提交于 
      This patch removes the IRQ-disable from mac_suspend.
The main advantage of this is to get rid of the IRQ-sync call in mac_suspend.
We need to remove the MAC suspend bit from the IRQ service mask, as otherwise
the IRQ handler would race with us.

      b43: Rewrite LO calibration algorithm · f5eda47f
      由 Michael Buesch 提交于 
      This patch distributes the Local Oscillator calibration bursts over time,
so that calibration only happens when it's actually needed.
Currently we periodically perform a recalibration of the whole table.
The table is huge and this takes lots of time. Additionally only small bits
of the table are actually needed at a given time. So instead of maintaining
a huge table with all possible calibration values, we create dynamic calibration
settings that
a) We only calibrate when they are actually needed.
b) Are cached for some time until they expire.
So a recalibration might happen if we need a calibration setting that's not
cached, or if the active calibration setting expires.
Currently the expire timeout is set to 30 seconds. We may raise that in future.

This patch reduces overall memory consumption by nuking the
huge static calibration tables.

This patch has been tested on several 4306, 4311 and 4318 flavours.
