| | * ath9k_htc: Fix an endian issueSujith Manoharan2011-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The stream length/tag fields have to be in little endian format. Fixing this makes the driver work on big-endian platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 4df3071ebd92ef7115b409da64d0eb405d24a631 "ath9k_hw: optimize interrupt mask changes", changed ath9k_hw_set_interrupts function to enable interrupts regardless of function argument, what could possibly be wrong. Correct that behaviour and check "ints" arguments before enabling interrupts, also disable interrupts if ints do not have ATH9K_INT_GLOBAL flag set.

When I tested ahb patch on bullet2 all seemed to work fine, but it couldn't connect another host (using ibss for example). During an analysis I observed that it's transmitting on another channel. I looked into madwifi code and understood that the problem is in channel setting function. So atheros RF2317 not fully handled in the current ath5k version and must be patched.

If the baseband hang occurs, the rx_clear signal will be stuck to high, so we can use the cycle counters to confirm it. With this patch, a hardware reset is only triggered if the baseband hang check returned true three times in a row, with a beacon interval between each check and if the busy time was also 99% or more during the check intervals.

However, the clearing of a separate MIC entry with hardware revisions that use combined MIC key layout did not do that with one of the registers. Add the matching register write to the following register to make the KEY4 register write actually complete. This is mostly a fix for a theoretical issue since the incorrect entry that could potentially be left behind in the key cache would not match with received frames. Anyway, better make this code clean the entry correctly using paired register writes. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

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.

To fix this, add those calls directly to ath_reset and drop them from callers where it makes sense. Also add them to the config callback around ath_update_txpow to fix a crash that happens when the tx power changed before any vif is brought up.

| * | ath9k_hw: do PA offset calibration only on longcal intervalRajkumar Manoharan2011-01-17

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).
