We need to provide a reasonable minimum that will result in a working setup if used. Set minimum to be 10 to provide for 4 standard TX queues + 1 command queue + 2 (unused) HCCA queues + 4 HT queues (one per AC). We allow the user to change the number of queues used via a module parameter and use this minimum value to check if it is valid. Without this patch a user can select a value for the number of queues that will result in a failing setup. Signed-off-by:

This ports the iwlwifi rfkill code to the new API offered by cfg80211 and thus removes a lot of useless stuff. The soft- rfkill is completely removed since that is now handled by setting the interfaces down. Signed-off-by:

Periodic RX interrupt needed with ICT interrupt to prevent RX race. 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:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by: -

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. Signed-off-by:

A few issues wrt DMA were uncovered when using the driver with swiotlb. - driver should not use memory after it has been mapped - iwl3945's RX queue management cannot use all of iwlagn because the size of the RX buffer is different. Revert back to using iwl3945 specific routines that map/unmap memory. - no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single, we can just call pci_unmap_single initially - only map the memory area that will be used by device. this is especially relevant to the mapping of iwl_cmd. we should not map the entire structure because the meta data at the beginning of structure contains the address to be used later for unmapping. If the address to be used for unmapping is stored in mapped data it creates a problem. - ensure that _if_ memory needs to be modified after it is mapped that we call _sync_single_for_cpu first, and then release it back to device with _sync_single_for_device - we mapped the wrong length of data for host commands, with mapped length differing with length provided to device, fix that. Thanks to Jason Andryuk <jandryuk@gmail.com> for significant bisecting help to find these issues. This fixes http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1964Signed-off-by:

This patch removes all the virtual A-MPDU-queue bookkeeping from mac80211. Curiously, iwlwifi already does its own bookkeeping, so it doesn't require much changes except where it needs to handle starting and stopping the queues in mac80211. To handle the queue stop/wake properly, we rewrite the software queue number for aggregation frames and internally to iwlwifi keep track of the queues that map into the same AC queue, and only talk to mac80211 about the AC queue. The implementation requires calling two new functions, iwl_stop_queue and iwl_wake_queue instead of the mac80211 counterparts. Signed-off-by:

Fixes: - iwlwifi is an optional driver and should thus not default to 'y'. - 3945 now depends on IWLCORE. Rework: - There is not a case when IWLCORE should not be selected. At the same time the driver does not use IWLWIFI or IWLCORE. We can just merge the usage of these two. With IWLWIFI being the driver name we proceed to use just it and replace instances of IWLCORE with it. The module name does not change and is still iwlcore. - Both IWLAGN and IWL3945 are selecting FW_LOADER, we can thus just move this up to one select when IWLWIFI is selected. - IWL5000 now supports Intel Wireless Wifi 100, 6000, and 6050 series. - Now that 3945 depends on IWLWIFI we can also indicate its dependency on MAC80211_LEDS and LEDS_CLASS at this level. - IWLAGN_LEDS is not used by driver - remove it. - IWLAGN_SPECTRUM_MEASUREMENT actually depends on IWLWIFI as it forms part of iwlcore module. Move this config up in Kconfig to reflect that and also change name to IWLWIFI_SPECTRUM_MEASUREMENT. - CONFIG_IWLWIFI_RFKILL is used by iwlagn as well as iwl3945, add text to description that indicates this. - CONFIG_IWL3945_RFKILL does not exist - remove usage from driver. - Add "iwlagn" to end of description of IWLAGN to help people understand what iwlagn means in rest of Kconfig text. - Add "iwl3945" to end of description of IWL3945 to help people understand what iwlagn means in rest of Kconfig text. - Change IWLWIFI_DEBUGFS description to indicate that only iwlagn supports it (for now).

The iwl_rxon_cmd is really just a iwl3945_rxon_cmd structure extension. So, we can use the *_rxon fields from iwl_priv instead of the 3945 specific ones (*39_rxon). We have to then be careful when submitting REPLY_RXON host commands, since the command length as to be set according to the HW. As another precaution the reserved4 and reserved5 fields are cleared before being sent to the 3945. With the *39_rxon removal, a lot of duplicated code can be removed from the 3945 code base.

By adding the eeprom ops to the 3945 code, we can now use the iwlcore eeprom routines (defined in iwl-eeprom.c). We also removed the heavy eeprom39 reference from iwl_priv and use the eeprom pointer instead. Signed-off-by:

By adding an additional hw_params (tfd_size) and a new iwl_lib ops (txq_init), we can now use the iwlcore TX queue management routines. We had to add a new hw_params because we need to allocate the right DMA buffer for TFDs, and those have a different sizes depending if you're on 3945 or agn. Signed-off-by:

Currently iwl3945 is not able to report hw-killswitch events while the interface is down. This has implications on user space tools (like NetworkManager) relying on rfkill notifications to bring the interface up once the wireless gets enabled through a hw killswitch. Thus, enable the device already in iwl3945_pci_probe instead of iwl3945_up and poll the CSR_GP_CNTRL register to update the killswitch state every two seconds. The polling is only needed on 3945 hardware as this adapter does not use interrupts to signal rfkill changes to the driver (in case no firmware is loaded). The firmware loading is still done in iwl3945_up. Signed-off-by:
