* ath9k: remove the two wiphys scanning at the same time messageLuis R. Rodriguez2010-07-281-4/+9
| | | | | | | | | | | | | | | | | | When issuing two consecutive scans you could often end up getting in the logs: "ath9k: Two wiphys trying to scan at the same time" This message is due to a race in mac80211 but addressing that race requires some more major changes on the driver and perhaps optimizations on mac80211 like removing the scan complete callback alltogether. Its too late to address this this kernel release so supress the complaint and annotate this needs fixing for later. Cc: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luis R.

* ath9k: Fix incorrect user ratekbs of MCS15 ShortGISenthil Balasubramanian2010-07-271-1/+1
| | | | | | | | | | | | | | The user ratekbs of MCS15 ShortGI is incorrect and can not be lesser than MCS15 rate. This incorrect rate may affect switching to higher rates as the rate control algorithm always finds MCS15 is better than MCS15 ShortGI and results in lower throughput. Fix this by feeding the correct user ratekbs for MCS15 ShortGI rate. This issue affects 3 stream case very badly as the 3 stream rates are not used at all once we scale down to MCS15 from 3 stream rates.

| | | | | | | | | | | | The noisefloor array index always corresponds to the rx chain number it belongs to (with an offset of 3 for the extension chain).

* ath9k_hw: Fix AR9003 MPDU delimeter CRC check for middle subframesLuis R. Rodriguez2010-07-161-2/+29
| | | | | | | | | | | | | | | | | | An A-MPDU may contain several subframes each containing its own CRC for the data. Each subframe also has a respective CRC for the MPDU length and 4 reserved bits (aka delimeter CRC). AR9003 will ACK frames that have a valid data CRC but have failed to pass the CRC for the MPDU length, if and only if the subframe is not the last subframe in an A-MPDU and if an OFDM phy OFDM reset error has been caught. Discarding those subframes results in packet loss under heavy stress conditions, an example being UDP video. Since the frames are ACK'd by hardware we need to let these frames through and process them as valid frames.

* ath5k: clean up rxlink handlingBruno Randolf2010-07-142-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: disable tasklets during resetBob Copeland2010-07-141-6/+14
| | | | | | | | | | | | | | | | Based on a patch from Bruno Randolf, attempting useful work while we are resetting the chip just leads to interface lockups and bad descriptor data, and possibly DMAing to freed buffers. Let's suspend all tasklets while reprogramming the registers in the card to avoid such problems. In the future we can convert the tasklets to threaded interrupt handlers to simplify things.

* ath5k: move reset to mac80211 workqueueBob Copeland2010-07-143-19/+24
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | The patch 'ath9k: fix a buffer leak in A-MPDU completion' addressed the issue of running out of buffers/descriptors in the tx path if a STA is deleted while tx status feedback is still pending.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AR5008+ and AR9003 currently use two separate implementations of the ath9k_hw_loadnf function. There are three main differences: - PHY registers for AR9003 are different - AR9003 always uses 3 chains, earlier versions are more selective - The AR9003 variant contains a fix for NF load timeouts This patch merges the two implementations into one, storing the register array in the ath_hw struct. The fix for NF load timeouts is not just relevant for AR9003, but also important for earlier hardware, so it's better to just keep one common implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the receive path gets stuck, a full hardware reset is necessary to recover from it. If this happens during a scan, the whole scan might fail, as each channel change bypasses the full reset sequence. Fix this by resetting the fast channel change flag if stopping the receive path fails.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When issuing a reset, the TSF value is lost in the hardware because of the 913x specific cold reset. As with some AR9280 cards, the TSF needs to be preserved in software here. Additionally, there's an issue that frequently prevents a successful TSF write directly after the chip reset. In this case, repeating the TSF write after the initval-writes usually works. This patch detects failed TSF writes and recovers from them, taking into account the delay caused by the initval writes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'bf_retries' field of the ath_buf structure was used for both software retries (AMPDU subframes) and hardware retries (legacy frames). This led to a wrong retry count being reported for the A-MPDU rate control stats. This patch changes the code to no longer use bf_retries for reporting retry counts, but instead always using the real on-chip retry count from the ath_tx_status. Additionally, if the first subframe of an A-MPDU was not acked, the tx status report is submitted along with the first acked subframe, which may not contain the correct rates in the tx info. This is easily corrected by saving the tx rate info before looping over subframes, and then copying it back once the A-MPDU status report is submitted. In my tests this change improves throughput visibly. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Reported-by: Björn Smedman <bjorn.smedman@venatech.se> Cc: stable@kernel.org Signed-off-by: John W.
