* iwlagn: move rate scale initialization to init functionReinette Chatre2009-11-02
| | | | | | | | | This fits better in how the callbacks operate (alloc does allocation and init does initialization). This also helps if we later want to do our own initialization without relying on the mac80211 allocation. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

* iwl3945: store station rate scale information in mac80211 station structureReinette Chatre2009-11-02
| | | | | | | | | | | | | Currently the rate scale information is pointed to from the mac80211 station structure but since that is the only member we might as well make it part of the structure. Also move the rate scaling initialization to the init function, no need to do it when we allocate the structure. This fits with how mac80211 deals with rate scaling information (it always calls init after allocation) and makes it easier for us to later call initialization directly.

* iwlwifi: split adding broadcast station from othersReinette Chatre2009-11-02
| | | | | | | | | | In preparation for some station management changes we split the addition of a broadcast station from the other stations.

* iwlwifi: move iwl_[un]init_drv to iwlagnReinette Chatre2009-11-02
| | | | | | | | | | Since iwlagn is the only user of these functions, move it to this module. This results in a bit more code moving than just these functions since the functions only used by them are also moved and we need to export the symbols previously available to them directly.

* iwlwifi: unmap memory before useReinette Chatre2009-11-02
| | | | | | | | | | | | | Handling responses to driver originated commands include passing the original command buffer to the caller. At this time it is possible for a callback to be invoked that is passed this command buffer and thus likely to access it. We need to make sure that the memory associated with that buffer is not DMA mapped at the time. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

* iwlagn: update write pointers for all tx queues after wakeupBen Cahill2009-11-02
| | | | | | | | | | | | | | Wakeup interrupt has been updating write pointers (indexes, actually) only for tx queues 0-5. This is adequate just for 3945, but inadequate for other devices, all of which have more tx queues. Now updating all tx/command queues, so device can be aware of all new tx and host commands enqueued while device was asleep. This can potentially improve data traffic bandwidth and/or latency.

* iwlwifi: remove power-wasting calls to apm_ops.init()Ben Cahill2009-11-02
| | | | | | | | | | | | | | | | | | To save power, don't run apm_ops.init() until needed at "up" time. EEPROM (5000 and earlier devices) may be read without running apm_ops.init(), but OTP reads (6000 and newer devices) require a powered-up chip. Therefore, remove apm_ops.init() from the general path in XXXX_pci_probe(), and call it only if device uses OTP. Once done with OTP read, call apm_ops.stop() to reset chip and save power until "up" time comes around. NOTE: This patch depends on removal of priv->lock from iwl_apm_stop(); lock does not get initialized until later in flow. See patch "remove unneeded locks from apm_stop()".

* iwlwifi: make sure device is reset when unloading driverBen Cahill2009-10-27
| | | | | | | | | | | | | | | | | | Add unconditional call to apm_ops.stop() to reset device to low power state when unloading driver. Some paths have existed to unload driver *without* resetting device, therefore some errors have persisted through multiple load/unload cycles, until the whole platform gets rebooted; this is an attempt to remedy some of those situations. Sorry, I can't seem to find a bughost.org bug that specifically has these symptoms, but I had it happen recently here. Note that this will *not* fix situations in which the PCI express bus has crashed (evidenced by register reads showing "0xffffffff"), e.g. bughost.org 1855 and 2096; device is unreachable from driver in those cases.

In the future, if we cannot avoid access the page after being handled to the upper layer, we can use get_page/put_page to handle it. For now, it's just not necessary.

* iwlagn: store station rate scale information in mac80211 station structureReinette Chatre2009-10-27
| | | | | | | | | | | | | Currently mac80211 initializes the rate scaling before notifying the driver of the station's existence. The driver dealt with this by not relying on mac80211's station notifications and instead mixing this functionality with the rate scaling code and other places.

* iwlwifi: use paged RxZhu Yi2009-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | This switches the iwlwifi driver to use paged skb from linear skb for Rx buffer. So that it relieves some Rx buffer allocation pressure for the memory subsystem. Currently iwlwifi (4K for 3945) requests 8K bytes for Rx buffer. Due to the trailing skb_shared_info in the skb->data, alloc_skb() will do the next order allocation, which is 16K bytes. This is suboptimal and more likely to fail when the system is under memory usage pressure. Switching to paged Rx skb lets us allocate the RXB directly by alloc_pages(), so that only order 1 allocation is required. It also adjusts the area spin_lock (with IRQ disabled) protected in the tasklet because tasklet guarentees to run only on one CPU and the new unprotected code can be preempted by the IRQ handler. This saves us from spawning another workqueue to make skb_linearize/__pskb_pull_tail happy (which cannot be called in hard irq context). Finally, mac80211 doesn't support paged Rx yet. So we linearize the skb for all the management frames and software decryption or defragmentation required data frames before handed to mac80211. For all the other frames, we __pskb_pull_tail 64 bytes in the linear area of the skb for mac80211 to handle them properly. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

* iwlwifi: dynamic allocate tx queue structureWey-Yi Guy2009-10-27
| | | | | | | | | | | Instead of always allocate the max number of tx queue structure, use dynamic allocation based on the number of queues in device configuration. With these changes, device does not have to allocate more memory than the h/w can support.

* iwl3945: move iwl_power_initialize()Ben Cahill2009-10-27
| | | | | | | | | | | | | | | iwl_power_initialize() initializes driver data (not device hardware), and does not need to execute more than once (when the driver initializes). Therefore, it does not belong in iwl3945_apm_init(), which initializes hardware, and may run more than once. Move it to iwl3945_pci_probe(), where it will run only once. This agrees with similar placement in iwl-agn.c's iwl_pci_probe(), although placement under "services" seemed more appropriate than under "mac80211".

* iwl3945: streamline iwl3945_rfkill_poll()Ben Cahill2009-10-27
| | | | | | | | | | | | iwl3945_rfkill_poll() has been silently calling wiphy_rfkill_set_hw_state() every 2 seconds, regardless of whether hardware RF KILL switch changed state. Call wiphy_rfkill_set_hw_state() only when RFKILL switch changes. Add IWL_DEBUG_RF_KILL log message and documentation.
