Currently we try to open an aggregation for every packet (given that one is not already open). This causes redundant overhead (addba/delba) for null data packets. Do not open an aggregation for null data packets. Signed-off-by:

Set the correct sta_id in the SCD_QUEUE_CONFIG command sent to the FW when enabling/disabling queues. This is needed in DQA-mode to allow the FW to associate between queue and STA. In case the queue isn't connected to a specific station but rather is a static "generic" queue - the sta_id should be set to 0x10 (max supported STA is 0x0f). Signed-off-by:

Support DQA queue sharing when no free queue exists for allocation to a STA that already exists. This means that a single queue will serve more than a single TID (although the RA will be the same for all TIDs served). We try to choose the lowest AC possible, to ensure the shared queues have the lowest possible combined AC requirements. The queue to share is chosen only from the same RA's DATA queues as follows (in descending priority): 1. An AC_BE queue 2. Same AC queue 3. Highest AC queue that is lower than new AC 4. Any existing AC (there always is at least 1 DATA queue) If any aggregations existed for any of the TIDs of the shared queue - they are stopped (the FW is notified), but no delBA is sent.

We never initialize ampdu_status so it causes a static checker warning when we pass it to iwl_mvm_pass_packet_to_mac80211(). Fortunately, it's never used so we can just remove it. Signed-off-by:

Some transports may sleep when writing to registers, which is done when calling iwl_force_nmi(). So we can't call iwl_force_nmi() in a timer context. To solve that, convert the scan timeout timer to a delayed work. Signed-off-by: -

Theoretically we may get only one IRQ from OS, in which case we will have only 1 queue even in MSIx mode. This will cause division by zero in the indirection table calculation. We do not need send the command in that case, as there is only one queue so all RX traffic will be directed to it anyway. Bail out early if there is only one queue. Signed-off-by:

Currently code calls restock for mq devices during the init function, unlike sq where restock is called after init. This causes an harmless but alarming deadlock warning from lockdep, to fix this - unify the init code. Rename the restock functions while at it. Signed-off-by:

Support marking queues as inactive upon a timeout expiring, and allow inactive queues to be re-assigned to other RA/TIDs if no other queue is free. This is done by keeping a timestamp of the latest frame TXed for every RA/TID, and then going over the queues currently in use when a new queue is needed, inactivating all those that are inactive.

Add support CSA countdown offloading. When CSA starts, the driver specifies the offsets to the eCSA and CSA IEs in the beacon template command and the fw performs the countdown.

For 9000 devices we can have PCIe bus for discrete devices and IOSF bus for integrated devices. PCIe supports maximum transfer size of 128B while IOSF bus supports maximum transfer size of 64B. Configure RB size accordingly. Signed-off-by:

Sara Sharon authored
Integrated 9000 devices have a bug with shadow registers value retention. If driver writes RBD registers while MAC is asleep the values are stored in shadow registers to be copied whenever MAC wakes up. However, in 9000 devices a MAC wakeup is not triggered and when the bus powers down due to inactivity the shadow values and dirty bits are lost. Turn on the chicken-bits that cause MAC wakeup for RX-related values as well when the device is in D0. When the device is in low power mode turn the RX wakeup chicken bits off since driver is idle and this W/A is not needed. Remove previous W/A which was ineffective. Signed-off-by:

In multiple RX queues architecture, the RX_PHY notification is no longer useful as it is received in the default queue even for packets that are received on RSS queue, and cannot be accessed without locking. All the needed data is in the new RX packet metadata and firmware will no longer send this notification for 9000 devices. Remove support of it. Signed-off-by:

We cannot trust NSSN for AMSDU sub-frames that are not the last. The reason is that NSSN advances on the first sub-frame, and may cause the reorder buffer to advance before all the sub-frames arrive. Example: Reorder buffer contains SN 0 & 2. We receive AMSDU with SN 1 and NSSN for first sub frame 3. The result us that driver releases SN 0,1, 2. When sub-frame 1 arrives - reorder buffer is already ahead and it will be dropped. If the last sub-frame is not on this queue - we will get frame release notification with up to date NSSN.

The new hardware that supports multiple queue also de-aggregates A-MSDUs. This means that we can advertise the maximal size of A-MSDUs regardless of the receive buffer's size. In order to be able to forcefully use a lower A-MSDU size, add a default value for the module parameter. Pre-9000 will have a default of 4K, and 9000 will have 12K. Setting the amsdu_size module parameter to 4K will limit the A-MSDU on 9000 as well. Signed-off-by:

When initializing RX we grab NIC access for every read and write. This is redundant - we can just grab access once. Signed-off-by:

The RX queues have a shadow register for the write pointer that enables updates without grabbing NIC access. Use them instead of the periphery registers because accessing those is much more expensive. Signed-off-by:

In non-shared queues, DQA requires re-configuring existing queues to become aggregated rather than allocating a new one. It also requires "un-aggregating" an existing queue when aggregations are turned off. Support this requirement for non-shared queues. Signed-off-by:

Johannes Berg authored
Newer hardware generations will take longer to be accessible again after reset, so we need to wait longer before continuing any flow that did a reset. Rather than make the wait time configurable, simply extend it for all. Since all of these code paths can sleep, use usleep_range() rather than mdelay(). Signed-off-by:
