| * debugfs: Pass bool pointer to debugfs_create_bool()Viresh Kumar2015-10-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument, when all it needs is a boolean pointer. It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.

Each 'scan plan' defines the number of scan cycles and the interval between scans. The scan plans are executed in the order they were configured. The last scan plan will always run infinitely and thus defines only the interval between scans. The maximum number of scan plans supported by the device and the maximum number of iterations in a single scan plan are advertised to userspace so it can configure the scan plans appropriately. When scheduled scan results are received there is no way to know which scan plan is being currently executed, so there is no way to know when the next scan iteration will start. This is not a problem, however. The scan start timestamp is only used for flushing old scan results, and there is no difference between flushing all results received until the end of the previous iteration or the start of the current one, since no results will be received in between.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When going into/coming out of D3, the TX PN must be programmed into and restored from the firmware respectively. The restore was broken due to my previous commit to move PN assignment into the driver. Sending the PN to the firmware still worked since we now use the counter that's shared with mac80211, but accessing it through the mac80211 API makes no sense now. Fix this by reading/writing the counter directly. This actually simplifies the code since we don't need to round-trip through the key_seq structure.

Fix this by using RS_PERCENT(). This bug caused the if branch to be always executed. This in turn led to always selecting a rate, following a column switch, in which the expected throughput would exceed the best expected current throughput. In some scenarios where the success ratio isn't >85% such a rate could be too aggressive leading us to avoid the new column. This has the potential of causing sub optimal performance.

| * | iwlwifi: mvm: stop using DEVICE_POWER_FLAGS_CAM_MSKJohannes Berg2015-10-052-10/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The firmware has always treated these two bits to mean that powersave is enabled when POWER_SAVE_ENA is set and CAM is clear; it doesn't use them in any non-combined way. Therefore, it's pointless to send it two bits, and the API should be cleaned up. Prepare the driver by removing the CAM bit and using only POWER_SAVE_ENA to indicate whether PS is enabled or not.

| * | iwlwifi: mvm: support enabling a queue with a given ssnLiad Kaufman2015-10-053-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When enabling a queue, the default SSN is 0. Allow determining what that SSN should be, if required. This can happen, for example, if a queue gets reconfigured. Signed-off-by: Liad Kaufman <liad.kaufman@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
| * | iwlwifi: mvm: support using multiple ACs on single HW queueLiad Kaufman2015-10-057-89/+249
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "DQA" is shorthand for "dynamic queue allocation", with the idea of allocating queues per-RA/TID on-demand rather than using shared queues statically allocated per vif. The goal of this is to enable future features (like GO PM) and to improve performance measurements of TX traffic. When RA/TID streams can't be neatly sorted into different AC queues, DQA allows sharing queues for the same RA. This means that DQA allows different ACs may reach the same HW queue. Update the code to allow such queue sharing by having a mapping between the HW queue and the mac80211 queues using it (as this could be more than one queue).

| | | | | | | | | | | | | | | | | | | | | | | | | | | As the transport will decide how many queues (and MSI-X vectors) to allocate, add a field to indicate that to the op-mode so it can size/allocate its own data structures appropriately.

| * | iwlwifi: op-mode API: add rx_rss methodJohannes Berg2015-10-051-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upcoming hardware will have the ability to do L3 hashing for RSS, directing data packets (and perhaps some associated metadata and management notifications) to different MSI-X vectors. In this case, it makes no sense to go through the full RX dispatch since it's already known that only a subset of the possibilities can come in, requiring a new receive method. In addition this must know which queue the packet was received on. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
| * | iwlwifi: mvm: remove PHY RX from handlersJohannes Berg2015-10-051-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Treat PHY RX specially, since it's actually pretty frequent, doesn't need all the notication etc. code, and will have a different handler in future hardware.
