2009-11-10iwlwifi: Use RTS/CTS as the preferred protection mechanism for 6000 seriesWey-Yi Guy
When 802.11g was introduced, we had RTS/CTS and CTS-to-Self protection mechanisms. In an HT Beacon, HT stations use the "Operating Mode" field in the HT Information Element to determine whether or not to use protection. The Operating Mode field has 4 possible settings: 0-3: Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT stations in a 20 MHz BSS Mode 1: used if there are non-HT stations or APs using the primary or secondary channels Mode 2: if only HT stations are associated in the BSS and at least one 20 MHz HT station is associated. Mode 3: used if one or more non-HT stations are associated in the BSS. When in operating modes 1 or 3, and the Use_Protection field is 1 in the Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or CTS-to-Self. By default, CTS-to-self is the preferred protection mechanism for less overhead and higher throughput; but using the full RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment. For 6000 series WIFI NIC, RTS/CTS protection mechanism is the recommended choice for HT traffic based on the HW design.

2009-09-28iwlwifi: fix 3945 ucode info retrieval after failureReinette Chatre
When hardware or uCode problem occurs driver captures significant information from device to enable debugging. The format of this information is different between 3945 and 4965 and later devices, yet currently the 3945 uses the 4965 and later format. Fix this by adding a new library call that is initialized to the correct formatting routine based on device. This moves the iwlagn event and error log handling back to iwl-agn.c to make it part of iwlagn module. Also remove the 3945 sysfs file that triggers dump of event log - there is already a debugfs file that can do it for all drivers.

2009-08-14iwlwifi: automatically adjust sleep levelJohannes Berg
Depending on required latency requested by pm_qos (via mac80211) we can automatically adjust the sleep state. Also, mac80211 has a user-visible dynamic sleep feature where we are supposed to stay awake after sending/receiving frames to better receive response frames to our packets, this can be integrated into the sleep command. Currently, and this patch doesn't change that yet, we default to using sleep level 1 if PS is enabled. With a module parameter to iwlcore, automatic adjustment to changing network latency requirements can be enabled -- this isn't yet the default due to requiring more testing. The goal is to enable automatic adjustment and then go into the deepest possible sleep state possible depending on the networking latency requirements. This patch does, however, enable IEEE80211_HW_SUPPORTS_DYNAMIC_PS to avoid the double-timer (one in software and one in the device) when transmitting -- the exact timeout may be ignored but that is not of big concern. Note also that we keep the hard-coded power indices around for thermal throttling -- the specification of that calls for using the specified power levels. Those can also be selected in debugfs to allow easier testing of such parameters.

2009-08-14iwlwifi: revert uCode Alive notification with timeoutReinette Chatre
commit "iwlwifi: uCode Alive notification with timeout" introduced a more reliable mechanism for ucode loading. Unfortunately we hit a problem with it frequently enough to make a 4965 unusable. The problem can be seen in debug log below. What this code attempts is to set runtime ucode up to load, start a timer to wait for the alive response from runtime ucode, and if it times out it tries again. As can be seen below we receive the alive response and wake the waiting task _before_ the tasks starts waiting. The task thus times out as the alive response is not received while it is waiting for it and it restarts the device. This starts the cycle all over again.

2009-08-14iwlwifi: re-introduce per device debuggingReinette Chatre
Commit "iwlwifi: make debug level more user friendly" cleaned up the debug level handling. In doing so it created a single global debug level for all devices. Some setups do consits of more that one iwlwifi device and in these setups there is a requirement that debug levels should be unique per device. We now re-introduce the per device debugging while maintaining the cleanup effort of the previous patch. The maintain the global debug level and now introduce a per-device debug level that will be used if it (the per-device debug level) is set. The per-device debug level can be controlled via the debug_level sysfs file while the global debug level is controlled by the debug module parameter.

2009-07-27iwlwifi: fix up command sendingJohannes Berg
The current command sending in iwlwifi is a bit of a mess: 1) there is a struct, iwl_cmd, that contains both driver and device data in a single packed structure -- this is very confusing 2) the on-stack data and the command metadata share a structure by embedding the latter in the former, which is also rather confusing because it leads to weird unions and similarly odd constructs 3) each txq always has enough space for 256 commands, even if only 32 end up being used This patch fixes these things: 1) rename iwl_cmd to iwl_device_cmd and keep track of command metadata and device command separately, in two arrays in each tx queue 2) remove the 'meta' member from iwl_host_cmd and only put in the required members 3) allocate the cmd/meta arrays separately instead of embedding them into the txq structure Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

If temperature is above CT_KILL exit threshold, uCode go backto sleep; if temperature is below CT_KILL exit threshold, uCode send Card State Notification response with appropriate CT_KILL status flag, and uCode remain awake, Driver receive Card State Notification Response and update the card temperature to the CT_KILL exit threshold.

2009-07-24iwlwifi: make debug level more user friendlyReinette Chatre
* Deprecate the "debug50" module parameter used to obtain 5000 series and up debugging. Replace it with "debug" module parameter to match with original driver and be consistent between them. The "debug50" module parameter can still be used, except that the module parameter is not writable in keeping with its previous state. We currently just mark it as "deprecated" and do not have it in the feature-removal-schedule. Some more cleanup of module parameters needs to be done and can then be entered together. * Only make "debug" module parameters visible if the driver is compiled with CONFIG_IWLWIFI_DEBUG. This will eliminate a lot of confusion where users think they have set debug flags but yet cannot see any debug output. * Make module parameters writable. This eliminates the need for the "debug_level" sysfs file, which can now also be deprecated and added to feature-removal-schedule. This file is in significant use though with many iwlwifi documents and text referring users to it. We can thus not take its removal lightly and keep it around. With iwlcore shared between iwlagn and iwl3945 we really do not need debug module parameters for each but can instead have one debug module parameter for the iwlcore module. The same issue is here as with the sysfs file - a lot of iwlwifi documentation and text (like bug reports) rely on iwlagn and iwl3945 having this module parameter, so changing this to a module parameter of iwlcore will have significant impact and we do not do this for that reason. One consequence of this patch is that if a user is running a system with both 3945 and later hardware then the setting of the one module parameter will affect the value of the other. The likelihood of this seems low - and even if this setup is present it does not seem like an issue for both modules to run with the same debug level.

Sending RX interrupt require many steps to be done in the the device: 1- write interrupt to current index in ICT table. 2- dma RX frame. 3- update RX shared data to indicate last write index. 4- send interrupt. This could lead to RX race, driver could receive RX interrupt but the shared data changes does not reflect that. this could lead to RX race, RX periodic will solve this race Signed-off-by: Mohamed Abbas <mohamed.abbas@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

2009-05-22iwlcore: Allow skb allocation from tasklet.Mohamed Abbas
If RX queue becomes empty then we need to restock the queue from tasklet to prevent ucode from starving. A caller to iwl_rx_allocate will decide if allocated buffer should come from GFP_ATOMIC or GFP_KERNEL.

2009-05-22iwlcore: support ICT interruptMohamed Abbas
Add ICT interrupt handler support, ICT should improve CPU utilization since it does not require target read which is very expensive. This interrupt handler only added to 5000 cards and newer. Device will write interrupts to ICT shared table to inform driver about its interrupts. These patches will not touch 3945 and 4965 interrupt handlers and tasklet.

2009-05-22iwlcore: register locksMohamed Abbas
Add new lock to be used when accessing some registers. Also move the register lock and iwl_grab_nic_access inside the function for register access. This will prevent from forgetting to hold locks and nic access in the right way and make code easier to maintain. We over use the priv->lock spin lock and I guess we need to add new one for Tx queue after that we might need to change most of these lock to BH and just keep priv->lock as irq type.

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.

2009-05-06Wireless: remove driver_data direct access of struct deviceGreg Kroah-Hartman
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions. Cc: John W.

2009-05-06mac80211: unify config_interface and bss_info_changedJohannes Berg
The config_interface method is a little strange, it contains the BSSID and beacon updates, while bss_info_changed contains most other BSS information for each interface. This patch removes config_interface and rolls all the information it previously passed to drivers into bss_info_changed.

2009-05-06mac80211: clean up beacon interval settingsJohannes Berg
We currently have two beacon interval configuration knobs: hw.conf.beacon_int and vif.bss_info.beacon_int. This is rather confusing, even though the former is used when we beacon ourselves and the latter when we are associated to an AP. This just deprecates the hw.conf.beacon_int setting in favour of always using vif.bss_info.beacon_int. Since it touches all the beaconing IBSS code anyway, we can also add support for the cfg80211 IBSS beacon interval configuration easily. NOTE: The hw.conf.beacon_int setting is retained for now due to drivers still using it -- I couldn't untangle all drivers, some are updated in this patch.

2009-04-22iwlwifi: remove radio disable parameter.Abhijeet Kolekar
Patch removes the "manual radio disable" parameter as there is no usage scenario of disabling radio using this module parameter. User can use iwconfig's txpower to enable and disable radio. This module parameter also does not work as expected. During module load the status of radio is set, the radio is not actually disabled. Even so, the moment mac80211 requests the interface to be up the radio will be enabled again.

This patch clean up the code for NL80211_IFTYPE_MONITOR mode, priv->iw_mode is set in add_interface, but add_interface is never called for monitor mode.
