* iwlwifi: move iwl_[un]init_drv to iwlagnReinette Chatre2009-11-02
| | | | | | | | | | Since iwlagn is the only user of these functions, move it to this module. This results in a bit more code moving than just these functions since the functions only used by them are also moved and we need to export the symbols previously available to them directly.

* iwlwifi: unmap memory before useReinette Chatre2009-11-02
| | | | | | | | | | | | | Handling responses to driver originated commands include passing the original command buffer to the caller. At this time it is possible for a callback to be invoked that is passed this command buffer and thus likely to access it. We need to make sure that the memory associated with that buffer is not DMA mapped at the time. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

* iwlagn: update write pointers for all tx queues after wakeupBen Cahill2009-11-02
| | | | | | | | | | | | | | Wakeup interrupt has been updating write pointers (indexes, actually) only for tx queues 0-5. This is adequate just for 3945, but inadequate for other devices, all of which have more tx queues. Now updating all tx/command queues, so device can be aware of all new tx and host commands enqueued while device was asleep. This can potentially improve data traffic bandwidth and/or latency.

| | | | | | | | | | | | Invoke workaround to avoid instability in L0->L0S->L1 transition on PCIe bus. Workaround disables L0S state so device moves directly from L0->L1.

* iwlwifi: remove power-wasting calls to apm_ops.init()Ben Cahill2009-11-02
| | | | | | | | | | | | | | | | | | To save power, don't run apm_ops.init() until needed at "up" time. EEPROM (5000 and earlier devices) may be read without running apm_ops.init(), but OTP reads (6000 and newer devices) require a powered-up chip. Therefore, remove apm_ops.init() from the general path in XXXX_pci_probe(), and call it only if device uses OTP. Once done with OTP read, call apm_ops.stop() to reset chip and save power until "up" time comes around. NOTE: This patch depends on removal of priv->lock from iwl_apm_stop(); lock does not get initialized until later in flow. See patch "remove unneeded locks from apm_stop()".

* iwlwifi: remove unneeded locks from apm_stop() and stop_master()Ben Cahill2009-11-02
| | | | | | | | | | | | | | | | | Since priv->reg_lock was added to keep multi-access register manipulation atomic, priv->lock protection is no longer needed. Remove this from iwl_apm_stop_master() and iwl_apm_stop(). Add warning of timeout when polling for busmaster disablement confirmation, and some comments. NOTE: This is needed to enable use of apm_ops.stop() within iwl_eeprom_init(); priv->lock does not get initialized until after this flow.

* libertas: remove internal buffers from GSPI driverAndrey Yurovsky2009-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the internal command and data buffers that the GSPI driver maintained and instead relies on the Libertas core to synchronize access to the command and data ports as with the other interface drivers. This cleanup reduces the GSPI driver's memory footprint and should improve performance by removing the need to copy to these internal buffers. This also simplifies the bottom half of the interrupt handler. This is an incremental cleanup: after removing the redundant buffers, we can further improve the driver to use a threaded IRQ handler instead of maintaining its own thread. However I would like a few folks to test the buffer removal first and make sure that I'm not introducing regressions. Tested on Blackfin BF527 with DMA disabled due to an issue with the SPI host controller driver in the current bleeding-edge Blackfin kernel. I would appreciate it if someone with working DMA could test this patch and provide feedback.

* ath9k_hw: Fix and complete force bias for AR5416Luis R. Rodriguez2009-10-30
| | | | | | | | | | | | | | | | Force bias is a fix for usage of AR5416 radios on the 2.4 GHz band for orientation sensitivity. This was only partially implemented with the ath9k_hw_decrease_chain_power() but first -- this was being called for all chipsets which is not correct and second -- it was missing the actual orientation code. We now ensure to only enable force bias only for AR5416 and BUG_ON() on other chipsets. Although ath9k_hw_decrease_chain_power() was enabled for newer chipsets I suspect that it never ran unless the EEPROM had ATH9K_ANT_FIXED_A or ATH9K_ANT_FIXED_B for antenna diversity.

* ath9k_hw: start documenting 802.11n RF anlong front endsLuis R. Rodriguez2009-10-30
| | | | | | | | | | | | | | | | | | | | | | Document what we can about the RF analog front ends (radios) of Atheros 802.11n devices. What should be clearer now is the what we do for old pre AR5416 and AR5418 MAC based devices in comparison to the modern sigle-chip 802.11n solutions. All devices after AR9280 are single chip and require less programming -- the RF registers no longer need to be initialized as they all have the RF analog front end embedded together with the MAC/BB; this includes the AR9271. Older devices such as the ones with the AR5416 MACs (PCI) or AR5418 MACs (PCI-E) have an external 2.4 GHz AR2133 radio or a dual band 2.4 GHz / 5 GHz AR5133 radio. These external radios require additional programming of the RF registers. Clarify which parts are for what devices and which code is shared. This patch has no functional changes.

The changes account for: * Supporting ar9271 1.0 and ar9271 1.1 together, the difference is bb_spectral_scan_ena, for 1.0 we'll set this to 0x1. * Ensuring we get the correct noise floor values -115 ~ -118 when we enable bb_enable_ant_div_lnadiv=0 and mc_tx_def_ant_sel=1. Previous to this we would get noise floor values in the range -50 ~ -80. To fix settings for the registers: - bb_ch1_xatten1_db - bb_ch1_xatten2_db - bb_ch1_xatten1_margin - bb_ch1_xatten2_margin - bb_ch1_gain_force - bb_ch1_xatten2_hyst_margin - bb_ch1_xatten1_hyst_margin - bb_ch1_max_oc_gain * 0x8120[2] mc_mic_new_location_enable is changed to 0x1. The MAC team suggest to set this value. * 0x9910[0] bb_spectral_scan_ena is changed to 0x0. For ar9271 1.1 we don't need to enable this bit.

* mac80211: remove RX_FLAG_RADIOTAPJohannes Berg2009-10-30
| | | | | | | | | | | | | | | | | | | | | | | While there may be a case for a driver adding its own bits of radiotap information, none currently does. Also, drivers would have to copy the code to generate the radiotap bits that now mac80211 generates. If some driver in the future needs to add some driver-specific information I'd expect that to be in a radiotap vendor namespace and we can add a different way of passing such data up and having mac80211 include it. Additionally, rename IEEE80211_CONF_RADIOTAP to IEEE80211_CONF_MONITOR since it's still used by b43(legacy) to obtain per-frame timestamps.
