Adding accumulative statistics counters in iwlwifi driver. Statistics counters are reported by uCode every beacon interval; but can be reset by uCode when needed. The accumulative statistics counters is maintained by driver to keep track of the history of all the counters. Update the ucode stats files in debugfs to display both latest and accumulative counters. Signed-off-by:

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. Signed-off-by:

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". Signed-off-by:

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. Signed-off-by:

The sleep_level_override debugfs file is used by the user to request a static power index instead of the dynamic sleep values. Users are expected to provide value from 1 to 5 as an index or -1 to disable it. The problem at the moment is that users can also provide 0 to this file which, together with the value 1, is translated to index 1. This is confusing and even more so when users write 0 to sleep_level_override and then read 1 from it afterwards. Modify checking to treat 0 as invalid. Signed-off-by:

Add more items to sensitivity range table to avoid using hardcoded values. Initialize the table per device since unique per device information is required to perform sensitivity calibration. additional items in sensitivity range table: .barker_corr_th_min: Barker correlation threshold minimum .barker_corr_th_min_mrc: Barker correlation threshold minimum for MRC .nrg_th_cca: Energy threshold for Clear Channel Assessment Barker codes are a technique used in WLAN encoding for transmission. MRC is "Maximal Ratio Combining", a technique for optimally combining the signals from 2 or more receivers to achieve a better signal. Signed-off-by:

"IWL_CMD_QUEUE_NUM" is being defined in multiple places and used by all the devices. move it to iwl-dev.h file and shared by all the devices. Remove "IWL_CMD_FIFO_NUM", replaced by "IWL49_CMD_FIFO_NUM" and IWL50_CMD_FIFO_NUM" Signed-off-by:

Now that we're unconditionally using apm_ops.stop() to reset and power-down the device in __iwl3945_down(), the apm_ops.reset() is redundant. Removing this call will also allow us to remove iwl3945_apm_reset(). Remove unneeded iwl_clear_bit(CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ) because this bit will be set again very soon in iwl3945_hw_txq_ctx_stop() and other following calls. Signed-off-by:

In some cases (e.g. when mac80211 calls iwl_mac_stop() for suspend or user no longer wants device active), device has not been going into low power state via __iwl_down(). apm_ops.reset() does not put device into low power state; instead it resets the device, then puts it into a powered-up state ready to be re-loaded with uCode and re-started. This has needlessly warmed up user's laptops and drained batteries. With current architecture in which mac80211 controls device up/down (including resetting device after firmware errors), there is no need for apm_ops.reset() any more; apm_ops.reset() is basically a combination of apm_ops.stop() and apm_ops.init(). Instead, __iwl_down() now unconditionally places the device into a low-power state via apm_ops.stop(). Device may be re-started via __iwl_up() calling apm_ops.init() as soon as it may be needed (e.g. quickly for firmware errors), but in the meantime, device will stop wasting energy. Note that, even in this low power state, if driver re-enables interrupts, the device retains the ability to sense the hardware RF-KILL switch, and (except for 3945) interrupt the host when it changes.

Update iwl3945_apm_init() to set up device registers in sequence most recently recommended by factory. Add resets for APMG interrupts and radio chip, formerly done only in iwl3945_apm_reset(); moving them here assures that apm_init() will do a complete job of preparing hardware not only after platform boot, but also after apm_stop() has executed (due to rfkill, ifconfig down, driver unload, etc.). This is in preparation to completely remove apm_reset(). Add some comments. Signed-off-by:
