* | ath5k: Skip powertable setting when we are on the same channelNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | * Only set power table if we are changing channel/mode there is no need to recalculate and reset the power table all the time. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | ath5k: Always set IFS intervals on resetNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | * Make sure we always set IFS timings even if no coverage class is set. If we don't we'll miss the needed changes for different bwmodes. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | ath5k: Set all IFS intervals, not just slot timeNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | * Replace set_slot_time with set_ifs_intervals that also sets the various inter-frame space intervals based on current bwmode. * Clean up AR5210 mess from reset_tx_queue, AR5210 only has one data queue and we set IFS intervals for that queue on set_ifs_intervals so there is nothing left to do for 5210 on reset_tx_queue.

* | ath5k: Extend rate_durationNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Extend ieee80211_generic_frame_duration to support the various bwmodes. * Better document what's going on with ack bitrates and update write_rate_duration to support the standard ack bitrates (when we don't set the high bit). * Get rid of set_ack_bitrate_high and introduce a flag on ath5k_hw for this (we only called the function on init anyway so there is no difference).

* | ath5k: Extend get_default_sifs/slot_timeNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | | | * Extend get_default_sifs/slot_time to include timings for turbo half and quarter rate modes. * AR5210 code for now uses timings already on core clock units instead of usecs so rename them (we 'll clean it up later).

* | ath5k: Increase PHY settling parameters for turo modeNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * On turbo mode increase PHY settling times, note that we only increase switch settling time on AR5212 as indicated by initvals. * A few cleanups: Move frame control settings for AR5210 from reset_tx_queue to tweak_initvals and remove phy_scal settings from tweak_initvals (we tweak them alread on set_sleep_clock).

* | ath5k: Small cleanup on tweak_initvalsNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | * Now that we properly set rx/tx latencies for AR5311 remove that old buggy part of code left inside ath5k_hw_tweak_initval_settings that was never executed (you can't have an RF5112 radio on a mac older than AR5212). Also use a magic value for 5311 PHY_SCAL value. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | ath5k: Add new field on ath5k_hw to track bandwidth modesNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | * Prepare for half/quarter/turbo support, introduce a new ah_bwmode parameter and get rid of ah_turbo. Bwmode stands for "bandwidth mode" and can have 4 values, default (20MHz), turbo (40MHz), half rate (10MHz), and quarter rate (5MHz).

* | ath5k: Use new function to stop beacon queueNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Since we only use ath5k_hw_stop_tx_dma to stop the beacon queue, introduce a new function ath5k_hw_stop_beacon_queue so that we can use that instead and have better control. In the future we can add more beacon queue specific stuff there (maybe tweak beacon timers or something), for now just call ath5k_hw_stop_tx_dma. * Also since we don't call ath5k_hw_stop_rx/tx_dma from outside dma.c, make them static.

* | ath5k: Use DCU early termination correctlyNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | * DCU early termination should be used to quickly flush QCU according to docs so don't enable it for all queues, enable it only when stopping each queue and disable it when we are done.

* | ath5k: Use new dma_stop function on base.cNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | * Since we stop rx/tx dma and pcu durring reset there is no need to call ath5k_hw_stop_rx/tx_dma before, also there is no need to call them durring stop_locked since we can use ath5k_hw_dma_stop for both.

| | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Ryan Niemi, some bitmasks in the register definition for the PCU Diagnostic register (DIAG_SW) were missing a zero at the end. While at it fix some typos and add more comments. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * | ath5k: Disable interrupts in ath5k_hw_get_tsf64Bruno Randolf2010-09-28
| | | | | | | | | | | | | | | | | | | | | | | | The code in ath5k_hw_get_tsf64() is time critical and will return wrong results if we get interrupted, so disable local interrupts. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * | ath5k: Increase "fudge" for beacon timersBruno Randolf2010-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | We use FUDGE to make sure the next TBTT is ahead of the current TU. Since we later substract AR5K_TUNE_SW_BEACON_RESP (10) in the timer configuration we need to make sure it is bigger than that. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.

| * | ath5k: Check and fix ATIM windowBruno Randolf2010-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds sanity-checks for the beacon timers and especially the ATIM window to ath5k. It is basically the same what i did for madwifi two years ago and fixes a problem in IBSS mode which has been described as "ramping" pings. See the code comments for a more detailed description and these links: http://madwifi-project.org/ticket/1154 http://madwifi-project.org/changeset/3867 http://thread.gmane.org/gmane.linux.drivers.madwifi.devel/6066 Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.

| * | ath5k: Remove unused variable for atim windowBruno Randolf2010-09-28
| | | | | | | | | | | | | | | | | | | | | It's not used and it's unlikely we will ever implement ATIM. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
