2013-06-18iwlwifi: mvm: allow firmware crashes to wake system for debugJohannes Berg3-0/+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. Reviewed-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-06-17iwlwifi: bump required firmware API version for 3160/7260Johannes Berg1-6/+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>

2013-06-13iwlwifi: create opmode/device dependenciesJohannes Berg3-2/+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.

2013-06-13iwlwifi: reduce debug ifdefs using the optimiserJohannes Berg4-33/+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.

2013-06-10rt2x00: rt2x00queue: initialize data_queue fields earlierGabor Juhos1-6/+38
Support for rt2800 device is broken since my 'rt2x00: rt2x00dev: use rt2x00dev->tx->limit' patch. 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.

The optional debugfs interface to the vendor's engineering tools wasn't bounds checking at all, which made it trivial to perform a buffer overflow if this interface was compiled in and then explicitly enabled at runtime. This patch checks both the length supplied as part of the data to ensure it is sane, and also the amount of data compared to the remaining buffer space. If either is too large, fail immediately.

2013-06-05iwlwifi: mvm: enable PM always in unassociated modeAlexander Bondar2-0/+5
In unassociated BSS STA mode FW verifies both power save and power management flags to decide on switching power off. The driver currently sets power management flag according to mac80211 decision. As result, in unassociated mode power management flag is down and power consumption is high. Change power management enablement. When unassociated in BPS and LP power save modes enable power management regardless of mac80211 decision. Rely on mac80211 decision if associated. Add power management state update during associated/disassociated modes transitions.

The AP mode needs to use the MCAST fifo for the MCAST frames sent after the DTIM. This fifo needs to be configured with the same parameters as the VOICE FIFO. A separate SCD queue is mapped to this fifo - the cab_queue (cab stands for Content After Beacon). This queue isn't connected to any station, but rather to the MAC context.

2013-06-04iwlwifi: mvm: Fix quota command settingsIlan Peer1-9/+16
According to the FW implementation, the quota command should have a valid entry for each active binding (where 'active' in this context means that the binding is known to the FW). In case the binding should not get any quota, the 'quota' should be set to zero. Not setting an 0 quota for an active binding when all the MACs in the binding are idle, i.e., not associated in case of managed interface, will result in preventing the FW scheduler from entering IDLE state and the FW from transitioning to low PS.
