2014-02-03iwlwifi: mvm: handle platform PCIe power limitationIdo Yariv1-1/+4
The tx backoff settings used by the thermal throttling mechanism can also be used for enforcing a limit on the power consumption of the module. Handle the platform PCIe power limitation by translating the limit (measured in mw) to its respective tx backoff value. The translation is module specific. The resulting tx backoff value is sent to the ucode, and also serves as the minimal backoff value that can be set by the thermal throttling mechanism.

Allow reading and setting bcast filtering configuration through debugfs. By default, mvm->bcast_filters is used for setting the bcast filtering configuration (these filters will be configured for each associated station). For testing purposes, allow overriding this configuration, and setting the bcast filtering configuration manually. The following debugfs keys can be used: * bcast_filtering/override - use debugfs values instead of default configuration * bcast_filtering/filters - set filters (+ attributes) * bcast_filtering/macs - per-mac bcast filtering configuration (policy + attached filters) Signed-off-by: Eliad Peller <eliadx.peller@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

Broadcast filtering allows dropping broadcast frames that don't match the configured patterns. Use predefined filters, and configure them for each associated station vif. There is no need to optimize and attach the same filter to multiple vifs, as a following patch will configure each filter to have per-vif unique values.

2013-12-31iwlwifi: mvm: dynamically update tsf_idIlan Peer1-0/+2
Currently, the MAC context tsf_id assignment and the master/slave relations are determined only when a new vif is added, as part of the MAC context resource allocation. However, at this stage, the beacon interval is not known, and thus could not be taken into account in the master-slave algorithm. To fix this, recalculate the MAC context tsf_id assignment, just before the MAC context is activated, i.e., just before a station VMAC is configured to associated and before an AP VMAC is started.

The smart FIFO is enabled when there is only one bound interface (other than p2p devices which are ignored) and it is of type station, and activated while the station is associated. Smart Fifo allows aggragations of DMA transactions and by that causes processor and memory controller to stay for a longer time on lower c-states, thus saving platform power.

This is the new API for BT Coex. The full functionality will be implemented in further patches. Note: this disables BT Coex for the currently existing fw (-7 version).
