* rt2x00: Make periodic beacon updates for PCI devices atomicHelmut Schaa2011-01-31
| | | | | | | | | | | | | Allow the beacondone and pretbtt functions to update the beacon from atomic context by using the beacon update functions with caller locking. This is a preparation for moving the periodic beacon handling into tasklets that require atomic context.

* rt2x00: Limit beacon updates in bss_info_changed to USB devicesHelmut Schaa2011-01-31
| | | | | | | | | | | | | | | | | | | Currently there are two places that trigger a beacon update on PCI devices. The bss_info_changed callback and the periodic update triggered by the TBTT or PRETBTT interrupt. Since the next TBTT or PRETBTT interrupt will periodically fetch an updated beacon remove the update_beacon call in the bss_info_changed callback for PCI devices. In the worst case it will take one beacon interval longer to fetch the new beacon then before. For devices that have a PRETBTT interrupt there should be no change at all.

* rt2x00: Introduce beacon_update_locked that requires caller lockingHelmut Schaa2011-01-31
| | | | | | | | | | | | | | Introduce a beacon_update_locked function that does not acquire the according beacon mutex to allow beacon updates from atomic context. The caller has to take care of synchronization. No functional changes. Just preparation for beacon updates from tasklet context.

* rt2x00: Refactor beacon code to make use of start- and stop_queueHelmut Schaa2011-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to dynamically remove beaconing interfaces without shutting beaconing down on all interfaces. The only place to start and stop beaconing are now the start- and stop_queue callbacks. Hence, we can remove some register writes during interface bring up (config_intf) and only write the correct sync mode to the register there. When multiple beaconing interfaces are present we should enable beaconing as soon as mac80211 enables beaconing on at least one of them. The beacon queue gets stopped when the last beaconing interface was stopped by mac80211. Therefore, introduce another interface counter to keep track ot the number of enabled beaconing interfaces and start or stop the beacon queue accordingly. To allow single interfaces to stop beaconing, add a new driver callback clear_beacon to clear a single interface's beacon without affecting the other interfaces. Don't overload the clear_entry callback for clearing beacons as that would introduce additional overhead (check for each TX queue) into the clear_entry callback which is used on the drivers TX/RX hotpaths. Furthermore, the write beacon callback doesn't need to enable beaconing anymore but since beaconing should be disabled while a new beacon is written or cleared we still disable beacon generation and enable it afterwards again in the driver specific callbacks. However, beacon related interrupts should not be disabled/enabled here, that's solely done from the start- and stop queue callbacks. It would be nice to stop the beacon queue just before the beacon update and enable it afterwards in rt2x00queue itself instead of the current implementation that relies on the driver doing the right thing. However, since start- and stop_queue are mutex protected we cannot use them for atomic beacon updates.

| * ath9k: Fix power save usage count imbalance on deinitRajkumar Manoharan2011-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While unloading the driver, the ps_usecount is incremented before configuring gpio registers in deinit_device. But it is failed to restore the ps_usecount after that. The problem is that the chip is forcibly moved to FULL SLEEP by radio_disable when mac80211 is reporting as idle though ps_usecount is not zero. This patch retores ps_usecount properly and ensures that the chip is always moved to full sleep only if ps usage count is zero which also helps in debugging deadbeef on multivif case. And also fixes the following warning. ath: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath9k/recv.c:536 ath_stoprecv+0xf4/0x100 [ath9k]() Cc: stable@kernel.org Cc: Paul Stewart <pstew@google.com> Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.

| * ath9k_hw: do PA offset calibration only on longcal intervalRajkumar Manoharan2011-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The power detector adc offset calibration has to be done on 4 minutes interval (longcal * pa_skip_count). But the commit "ath9k_hw: fix a noise floor calibration related race condition" makes the PA calibration executed more frequently beased on nfcal_pending value. Running PAOffset calibration lesser than longcal interval doesn't help anything and the worse part is that it causes NF load timeouts and RX deaf conditions. In a very noisy environment, where the distance b/w AP & station is ~10 meter and running a downlink udp traffic with frequent background scan causes "Timeout while waiting for nf to load: AR_PHY_AGC_CONTROL=0x40d1a" and moves the chip into deaf state. This issue was originaly reported in Android platform where the network-manager application does bgscan more frequently on AR9271 chips. (AR9285 family usb device).

* | ath5k: use tracing for packet tx/rx dumpBob Copeland2011-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a few tracepoints to ath5k driver transmit and receive callbacks in order to record packet traffic. We record the entire packet in the trace buffer so that the data can be extracted with trace-cmd and external plugins. Compared to the previous debugging calls, this approach removes an out-of-line function call from the tx and rx paths in the compiled-in-but-disabled case, while improving the ability to process the logged data. A new option, CONFIG_ATH5K_TRACER, is added so that one may disable the tracepoints completely.

* | ath5k: Enable 802.11j 4.9GHz frequenciesBruno Randolf2011-01-28
| | | | | | | | | | | | | | | | This enables 4.9GHz frequencies in ath5k if they are allowed as indicated by the regulatory domain code. Currently this is MKK9_MKKC (0xfe). Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | ath: Add function to check if 4.9GHz channels are allowedBruno Randolf2011-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a helper function to ath/regd.c which can be asked if 4.9GHz channels are allowed for a given regulatory domain code. This keeps the knowledge of regdomains and defines like MKK9_MKKC in one place. I'm passing the regdomain code instead of the ath_regulatory structure because this needs to be called quite early in the driver inititalization where ath_regulatory is not available yet in ath5k. I'm using MKK9_MKKC only because this is the regdomain in the 802.11j enabled sample cards we got from our vendor. I found some hints in HAL code that this is used by Atheros to indicate 4.9GHz channels support and that there might be other domain codes as well, but as I don't have any documentation I'm just putting in what I need right now. It can be extended later. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
