* ath5k: disable 5 GHz support for the dualband PHY chip on dual-radio AR5312Felix Fietkau2011-04-141-1/+2
| | | | | | | | | | | | | | There are two variants of AR5312 dual-band devices, one single-radio and the other one dual-radio. On the dual-radio board, the first MAC only supports 5 GHz, even though it has a dual-band PHY. The 2.4 GHz part of this phy is used in pass-through mode, connecting the second MAC with the second PHY. Disable 2.4 GHz for the first MAC on an AR5312, but only if the board configuration indicates a dual-radio device.

* ath5k: Fix surveyBruno Randolf2010-12-161-0/+2
| | | | | | | | | | | | | | The old survey implementation was broken and returned nonsense data. Clear cycle counters and survey data on reset. Since the cycle counters easily overflow it's better to keep a local version of collected survey data (in ms resolution, instead of clockrate) and update this every time survey is retrieved. If survey is retrieved often enough to avoid cycle counter overflows this works fine, otherwise we could update survey more often, like ath9k does. Still only the survey for the current channel is kept. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath5k: Use four hardware queuesBruno Randolf2010-09-211-1/+4
| | | | | | | | | | | | | | | Prepare ath5k for WME by using four hardware queues. The way we set up our queues matches the mac80211 queue priority 1:1, so we don't have to do any mapping for queue numbers. Every queue uses 50 of the total 200 available transmit buffers, so the DMA memory usage does not increase with this patch, but it might be good to fine-tune the number of buffers per queue later (depending on the CPU speed and load, and the speed of the medium access, it might not be big enough).

* ath5k: clean up rxlink handlingBruno Randolf2010-07-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a few places where the sc->rxlink pointer was set to NULL "just in case". This helps nothing - quite to the contrary it is problematic since it can create self-linked rx descriptors in the middle of the list of receive buffers. Here is an example how this could happen (thanks Bob!): cpu 0: cpu 1: ath5k_rx_stop ath5k_tasklet_rx sc->rxlink = NULL; /* just in case */ // following doesn't link used // buffer to prev. ath5k_rxbuf_setup() In the case of ath5k_rx_stop() and ath5k_stop_locked() buffers/descriptors are not changed so rxlink should not be changed as well. In ath5k_intr() we seem to try to work around a hardware bug, as the comment (which is copied 1:1 from the HAL) suggests. I don't see how this could help. Also the HAL does not set rxlink in this case (So where does this code come from? It has been there since the first import of ath5k). Changed to just increment a statistics counter. After this patch rxlink is only set to NULL before we initialize rx descriptors and updated when the descriptors are linked together.

* ath5k: move reset to mac80211 workqueueBob Copeland2010-07-141-1/+2
| | | | | | | | | | | | | | | | | We currently trigger a reset via a tasklet when certain error conditions are detected so that the card will (eventually) restart. Unfortunately this makes locking complicated since reset can also be called in process context (e.g. for channel change). Currently nothing protects against concurrent resets, which can be the source of corruption bugs. Reset takes too long to spinlock the whole thing, so this patch moves deferred resets into the mac80211 workqueue to enable use of sc->lock mutex.

* ath5k: treat RXORN as non-fatalBruno Randolf2010-04-141-0/+1
| | | | | | | | | | | | | | | | | | | We get RXORN interrupts when all receive buffers are full. This is not necessarily a fatal situation. It can also happen when the bus is busy or the CPU is not fast enough to process all frames. Older chipsets apparently need a reset to come out of this situration, but on newer chips we can treat RXORN like RX, as going thru a full reset does more harm than good, there. The exact chip revisions which need a reset are unknown - this guess AR5K_SREV_AR5212 ("venice") is copied from the HAL. Inspired by openwrt 413-rxorn.patch: "treat rxorn like rx, reset after rxorn seems to do more harm than good" Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.

* ath5k: Adaptive Noise Immunity (ANI) ImplementationBruno Randolf2010-04-071-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked at both ath9k and HAL sources (they are nearly the same), and even though i have implemented some things differently, the basic algorithm is practically the same, for now. I hope that this can serve as a clean start to improve the algorithm later. This also adds a possibility to manually control ANI settings, right now only thru a debugfs file: * set lowest sensitivity (=highest noise immunity): echo sens-low > /sys/kernel/debug/ath5k/phy0/ani * set highest sensitivity (=lowest noise immunity): echo sens-high > /sys/kernel/debug/ath5k/phy0/ani * automatically control immunity (default): echo ani-on > /sys/kernel/debug/ath5k/phy0/ani * to see the parameters in use and watch them change: cat /sys/kernel/debug/ath5k/phy0/ani Manually setting sensitivity will turn the automatic control off. You can also control each of the five immunity parameters (noise immunity, spur immunity, firstep, ofdm weak signal detection, cck weak signal detection) manually thru the debugfs file. This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | * Get rid of calibration timer, instead use a software interrupt to schedule the calibration tasklet. a) We don't need a timer for this, there is no need for accuracy even with round_jiffies i think this is a waste of resources. Also we don't need to run calibration if we are idle (no interrupts). b) When we add ANI support we 'll just extend the poll function and calibration tasklet and handle all periodic phy calibration on one place (much cleaner). c) Having calibration on a tasklet is better since during calibration we can't transmit or receive (antennas are detached to measure noise floor), previously calibration could run in parallel with tx/rx and interfere (packet loss). v2: kill tasklet on stop_hw, stop/wake queues v3: use time_is_before_eq_jiffies to compare timestamp with current time Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

* ath5k: rework beacon configurationBob Copeland2009-07-101-0/+1
| | | | | | | | | | | | | | | | | | | | | Using the enable_beacon flag allows some simplifications and fixes some corner cases in beacon handling. This change adds a state variable for beaconing in ath5k_beacon_config and handles both enabling and disabling, thus eliminating the need for ath5k_beacon_disable. We also now configure the beacon when any of the beacon parameters change, so ath5k_beacon_reconfig is no longer needed (its mmiowb gets moved to ath5k_beacon_config). Finally, by locking around the whole config function, we don't need to worry about clearing the interrupt mask register before installing the new mask. The upshot is this correctly disables beaconing when the interfaces are taken down, it fixes a potential restarting of beaconing when ath5k_reset() is called, and ensures that updates to the beacon interval take effect immediately.
