* iwlwifi: mvm: allow firmware crashes to wake system for debugJohannes Berg2013-06-183-0/+10
| | | | | | | | | When the D3 firmware crashes, it can be helpful for debugging to resume the system to get the SRAM snapshot to see why it crashed. Allow enabling this with a debugfs option.

* iwlwifi: bump required firmware API version for 3160/7260Johannes Berg2013-06-171-6/+6
| | | | | | | | | | As the firmware API has changed significantly and we don't have support code for the old APIs, bump the version to be able to release the version 7 API firmware. Unfortunately this means that the driver in 3.9 and 3.10 can't work, but that's still better than crashing the device/driver there. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* iwlwifi: create opmode/device dependenciesJohannes Berg2013-06-133-2/+12
| | | | | | | | | | | | | The older devices (pre-7000/3000 series) all only work with the DVM opmode due to firmware availability, while newer ones will only work with the MVM opmode for the same reason. When building a driver that only has one of MVM or DVM, there's no reason to build the device support and have the PCIe IDs for all devices since they can't be used anyway, so avoid that.

* iwlwifi: reduce debug ifdefs using the optimiserJohannes Berg2013-06-134-33/+16
| | | | | | | | | | | Instead of using #ifdef CONFIG_IWLWIFI_DEBUG, remove the iwlwifi_mod_params.debug_level variable completely and make iwl_have_debug_level() always return false in the non-debug case. This way, the optimiser will elide all code for it automatically without having to add #ifdefs.

| | | | | | | | | | | | | | There's no reason to read the INTA register in the ICT IRQ handler, this interrupt mechanism is designed to not have to read as many registers as the regular one. Not reading the INTA register gives a significant performance/CPU use improvement. Since we still want to get this info, fetch it only if the ISR debug level is enabled.

| * rt2x00: rt2x00queue: initialize data_queue fields earlierGabor Juhos2013-06-101-6/+38

The changelog of that commit says that the TX data queue is initialized already when the rt2x00lib_probe_hw() function is called. However as Jakub noticed it, this statement is not correct. The queue->limit field is initialized in the rt2x00queue_alloc_entries routine and that is not yet called when rt2x00lib_probe_hw() runs. Because the value of tx->limit contains zero, the driver tries to allocate a kernel fifo with zero size and kfifo_alloc rejects that with -EINVAL. PCI: Enabling device 0000:01:00.0 (0000 -> 0002) ieee80211 phy1: rt2x00_set_rt: Info - RT chipset 3071, rev 021c detected ieee80211 phy1: rt2x00_set_rf: Info - RF chipset 0008 detected ieee80211 phy1: rt2x00lib_probe_dev: Error - Failed to initialize hw rt2800pci: probe of 0000:01:00.0 failed with error -22 Move the data_queue field initialization from the rt2x00queue_alloc_entries routine into the rt2x00queue_init function. The initialization code is not strictly related to the allocation, and the change ensures that the queue_data fields can be used in the probe routines. The patch also introduces a helper function in order to be able to get the correct data_queue_desc structure for a given queue. This helper is only needed temporarily and it will be removed later.
