Add support to enable beacon early termination in the firmware. Early Beacon termination is a feature which allows the radio to be turned off after TIM IE to save power. Signed-off-by:

If the 38.4MHz reference clock is configured to the firmware, it crashes on boot. Configuring an experimental 38.4MHz in XTAL mode allows the firmware to boot, and everything appears to work. Signed-off-by:

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:

We were using the join command to change some settings when the stack asked us to do it. In many cases they were not needed (and could cause potential problems), so they were removed. In other cases there are ACX commands that can be used instead of using join to reconfigure. Signed-off-by:

Luciano Coelho authored
We shouldn't use a join command to change the filter settings while associated. The right way to do it is to use ACX_RX_CFG. Signed-off-by:

With the change to the new firmware, there was a change to firmware memory partitioning. Along with that change, the translation of all partitions was unified, and separate functions for reg and mem access became unnecessary. Cleanup the unnecessary functions. Signed-off-by:

We still don't have proper calibration for our devices, so we are using way too much power for TX, which causes a lot of distortion. This hack hardcodes the txpower to 7dBm. Signed-off-by:

We don't get any indication from the stack when we have disassociated. In wl1271, it is important to send a CMD_DISCONNECT before joining again, because the firmware cleans some things up. So we check if we're already joined and disconnect if that's the case. Signed-off-by:

Channel switch host command has different data structure for different devices. Adding additional structures to support 5000 and 6000 NICs. unlike 4965, starting with 5000 series, the tx power is managed by uCode, there is no tx power db information need to be passing from driver to uCode; but the space needs to be reserved to match uCode expection. 1000 NIC do not support channel switch operation since it is 'bgn' device, there is no need to have data structure defined for it.

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:

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:
