2014-05-13iwlwifi: remove CMD_SYNCEmmanuel Grumbach1-1/+1
CMD_SYNC is really 0 which is confusing: if (cmd.flags & CMD_SYNC) is always false. Fix this by simply removing its definition. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

Remove a spurious blank line in the quota code. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-03-18iwlwifi: mvm: remove using max_duration in firmware APIJohannes Berg1-21/+1
The firmware decided to not implement this API in this way, so for now remove setting the field completely. This will allow the firmware to change how to use this field later. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-02-03iwlwifi: mvm: fix quota allocationIlan Peer1-8/+28
Divide the maximal quota between all the data interfaces even in the case of a single low latency binding without any other non low latency interfaces, so that afterwards the quota allocation (which considers the number of data interfaces) will be correct.

2014-02-03iwlwifi: mvm: add the quota remainder to a data bindingIlan Peer1-2/+7
Currently the quota remainder was added to the first binding, although it is possible that this was not a data binding (only the P2P_DEVICE interface is part of the binding). Fix this by adding the remainder to the first binding that was actually allocated quota.

2014-02-03iwlwifi: mvm: limit non-low-latency binding scheduling durationJohannes Berg1-7/+26
Limit the scheduling duration of bindings without a low-latency interface in the firmware, this prevents those bindings from occupying the medium for a period of time longer than what we want for the other interfaces in low-latency mode. As older firmware doesn't do anything with the max_duration field and ignores it completely, there's no need for a firmware flag.

2014-02-03iwlwifi: mvm: reserve bandwidth for low-latency interfaceJohannes Berg1-14/+49
If there is/are interface(s) in low-latency mode, reserve a percentage (currently 64%) of the quota for that binding to improve the quality of service for those interfaces. However, if there's more than one binding that has low-latency, then give up and don't reserve, we can't allocate more than 100%.

2013-12-09iwlwifi: mvm: quota command max_duration should be zeroJohannes Berg1-2/+1
For now, the firmware doesn't really use the field, but it should be set to zero if there's no specific request. Setting it to the max quota doesn't make sense.

2013-10-11iwlwifi: mvm: add IBSS supportJohannes Berg1-6/+3
At the firmware level, IBSS support has similar programming requirements as AP/GO support, so use the same functions with just small differences. With IBSS only a single virtual interface can be used, so no changes in the advertised interface combinations are needed. For now, don't use hardware crypto for the GTKs in IBSS mode, the firmware should support it though.

2013-08-06iwlwifi: mvm: small cleanups in quota management codeJohannes Berg1-6/+5
Use a C99 initializer to clear the command and move the lockdep assertion before the restart check. Since this causes problems with the BUILD_BUG_ON() with some compilers, change that a bit. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-07-31iwlwifi: mvm: assign quota per virtual interfaceJohannes Berg1-8/+8
Instead of assigning quota per used binding (channel) assign the same amount of quota for each virtual interface so that when there are more than two interfaces using more than one channel, we'll stay on the channels proportionally to the number of virtual interfaces using the channels.

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.

2013-03-20iwlwifi: mvm: Fix quota handling for monitor interfaceIlan Peer1-1/+2
1. Quota for the monitor interface should be added only if there is a channel context assigned to the interface. 2. In the unassign channel context flow, need to remove the quota for the monitor interface binding, before unbinding.

2013-02-11iwlwifi: mvm: Update quota settings for all bindingsIlan Peer1-5/+24
The FW scheduler, schedules the bindings over a session of 128 fragments (each is 4 TU long). The quota command should allocate all the session fragments between all the bindings that require quota allocation. Currently, use static allocation, where the fragments are equally distributed between all data bindings. Note, that not allocating all the session's fragments might cause the FW scheduler to leave the medium unused.

2013-02-01iwlwifi: add the MVM driverJohannes Berg1-0/+178
Newer firmware revisions have a completely new firmware API. This is the new driver for this new API. I've listed the people who directly contributed code, but many others from various teams have contributed in other ways.
