* ath9k: fix compile error in non-debug ath_debug_stat_tx() stubFelix Fietkau2011-01-281-1/+2

* ath9k: fix tx queue index confusion in debugfs codeFelix Fietkau2011-01-281-1/+1
| | | | | | | | | | | | | | | | | | Various places printing tx queue information used various different ways to get a tx queue index for printing statistics. Most of these ways were wrong. ATH_TXQ_AC_* cannot be used as an index for sc->tx.txq, because it is only used internally for queue assignment. One place used WME_AC_* as a queue index for sc->debug.stats.txstats, however this array uses the ath9k_hw queue number as well. Fix all of this by always using the ath9k_hw queue number as an index, and always looking it up by going through sc->tx.txq_map.

* ath9k: rework tx queue selection and fix queue stopping/wakingFelix Fietkau2010-11-151-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current ath9k tx queue handling code showed a few issues that could lead to locking issues, tx stalls due to stopped queues, and maybe even DMA issues. The main source of these issues is that in some places the queue is selected via skb queue mapping in places where this mapping may no longer be valid. One such place is when data frames are transmitted via the CAB queue (for powersave buffered frames). This is made even worse by a lookup WMM AC values from the assigned tx queue (which is undefined for the CAB queue). This messed up the pending frame counting, which in turn caused issues with queues getting stopped, but not woken again. To fix these issues, this patch removes an unnecessary abstraction separating a driver internal queue number from the skb queue number (not to be confused with the hardware queue number). It seems that this abstraction may have been necessary because of tx queue preinitialization from the initvals. This patch avoids breakage here by pushing the software <-> hardware queue mapping to the function that assigns the tx queues and redefining the WMM AC definitions to match the numbers used by mac80211 (also affects ath9k_htc). To ensure consistency wrt. pending frame count tracking, these counters are moved to the ath_txq struct, updated with the txq lock held, but only where the tx queue selected by the skb queue map actually matches the tx queue used by the driver for the frame.

* ath9k: enable the baseband watchdog events for AR9003Luis R. Rodriguez2010-06-021-0/+2
| | | | | | | | | | | | | | | | | This enables the baseband watchdog events for the AR9003 family on ath9k. Upon an a baseband watchdog interrupt we reset the hardware, this should address corner case conditions where normal operation can stall. Enable ATH_DBG_RESET to be able to review details of the bb watchdog interrupt once it happens. If you're curious how often this happens just grep the debugfs interrupt file.

| | | | | | | | | | This patch passes in a pointer to the ath_rx_status data structure for functions that need it, instead of letting them grab it directly from the ath_desc struct.

* ath9k: separate debugfs support from CONFIG_ATH_DEBUGFelix Fietkau2009-11-281-3/+3
| | | | | | | | | | | | In my setups, ath9k's debugfs files are most of the time much more useful than the messages generated by enabling CONFIG_ATH_DEBUG along with the right debug flags. Since CONFIG_ATH_DEBUG comes with a noticeable overhead on embedded systems, this patch makes it possible to use the debugfs files without that option.

* ath9k: properly use the mac80211 rate control apiFelix Fietkau2009-11-281-2/+3
| | | | | | | | | | | This patch changes ath9k to pass proper MCS indexes and flags between the RC and the rest of the driver code. sc->cur_rate_table remains, as it's used by the RC code internally, but the rest of the driver code no longer uses it, so a potential new RC for ath9k would not have to update it.

* ath9k: Fix PS mode operation to receive buffered broadcast/multicast framesJouni Malinen2009-05-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | The previous implementation was moving back to NETWORK SLEEP state immediately after receiving a Beacon frame. This means that we are unlikely to receive all the buffered broadcast/multicast frames that would be sent after DTIM Beacon frames. Fix this by parsing the Beacon frame and remaining awake, if needed, to receive the buffered broadcast/multicast frames. The last buffered frame will trigger the move back into NETWORK SLEEP state. If the last broadcast/multicast frame is not received properly (or if the AP fails to send it), the next Beacon frame will work as a backup trigger for returning into NETWORK SLEEP. A new debug type, PS (debug=0x800 module parameter), is added to make it easier to debug potential power save issues in the future. Currently, this is only used for the Beacon frame and buffered broadcast/multicast receiving. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.
