2009-05-11iwlagn: improve rate scale table searchMohamed Abbas
iwlagn rate scaling will periodically search other rate scale tables to switch to the best table regarding performance. In the past the number of search tables were 3. Every time the rate scale algorithm goes through these available tables in will stay in current table for some time before start searching again. Recent driver support more feature and antenna, so we have more tables to search. This patch make sure we go through all available tables.

2009-05-11iwlwifi: clean up PS codeJohannes Berg
This removes all the dead code that tries to adjust the power saving level based on the system AC state (inacceptable policy in the kernel) or based on overtemp conditions (unused). Also, pass _all_ policy wrt. enabling PS to mac80211, since we do not use the power_disabled internally I now use that to mirror the mac80211 CONF_PS setting. When mac80211 turns off CONF_PS we follow suit. This means that the user power level (which can currently only be set from sysfs) is not touched for mac80211 powersave changes. This means no "association status" checks are necessary since mac80211 will not allow power save to be enabled when not associated.

2009-05-11iwlwifi: fix PS disable status raceJohannes Berg
iwlwifi internally needs to keep track of whether PS is enabled in the firmware or not. To do this, it keeps a bit in the status flags, called STATUS_POWER_PMI. The code to set this bit looks as follows: static int iwl_set_power(struct iwl_priv *priv, void *cmd) { return iwl_send_cmd_pdu_async(priv, POWER_TABLE_CMD, sizeof(struct iwl_powertable_cmd), cmd, NULL); } int iwl_power_update_mode(...) { [...] if (final_mode != IWL_POWER_MODE_CAM) set_bit(STATUS_POWER_PMI, &priv->status); iwl_update_power_cmd(priv, &cmd, final_mode); cmd.keep_alive_beacons = 0; if (final_mode == IWL_POWER_INDEX_5) cmd.flags |= IWL_POWER_FAST_PD; ret = iwl_set_power(priv, &cmd); if (final_mode == IWL_POWER_MODE_CAM) clear_bit(STATUS_POWER_PMI, &priv->status); else set_bit(STATUS_POWER_PMI, &priv->status); if (priv->cfg->ops->lib->update_chain_flags && update_chains) priv->cfg->ops->lib->update_chain_flags(priv); [...] } Now, this bit really needs to track what the _firmware_ thinks, not what the driver thinks. Therefore, there is a race condition here -- the driver sets the bit before it knows that the async command sent to the card in the iwl_set_power function has been processed. As a result, the call to update_chain_flags() may think that the card has been woken up (PMI bit cleared) while in reality it hasn't processed the async POWER_TABLE_CMD yet. This leads to bugs -- any commands the update_chain_flags function sends can get stuck and subsequent commands also fail. The fix is almost trivial: since there's no reason to send an async command here (in fact, there almost never should be since many mac80211 callbacks can sleep) just make the function wait for the card to process the command and then return and clear the PMI bit.

2009-05-07ixgbe: fix failing to log fan failuresDon Skidmore
We weren't logging the 82598AT fan failure if it occurred before (ixgbe_open) as we hadn't sent up to catch the interrupt that event caused. This patch checks for this failure in: ixgbe_probe - So we can log the failure asap. We check right after we set up the adapter->flags, which is when we know that we have a fan. ixgbe_up_complete - To catch failures that may have happened between probe and when we set up the interrupt that would normally detect the fan failure. To enable all of this we need to initialize the adapter flag with IXGBE_FLAG_FAN_FAIL_CAPABLE when the NIC contained a fan.

2009-05-06bnx2: Fix panic in bnx2_poll_work().Michael Chan
Add barrier() to bnx2_get_hw_{tx|rx}_cons() to fix this issue: http://bugzilla.kernel.org/show_bug.cgi?id=12698 This issue was reported by multiple i386 users. Without barrier(), the compiled code looks like the following where %eax contains the address of the tx_cons or rx_cons in the DMA status block. The status block contents can change between the cmpb and the movzwl instruction. The driver would crash if the value was not 0xff during the cmpb instruction, but changed to 0xff during the movzwl instruction. 6828: 80 38 ff cmpb $0xff,(%eax) 682b: 0f b7 10 movzwl (%eax),%edx With the added barrier(), the compiled code now looks correct: 683d: 0f b7 10 movzwl (%eax),%edx 6840: 0f b6 c2 movzbl %dl,%eax 6843: 3d ff 00 00 00 cmp $0xff,%eax Thanks to Pascal de Bruijn <pmjdebruijn@pcode.nl> for reporting the problem and Holger Noefer <hnoefer@pironet-ndh.com> for patiently testing test patches for us.
