When 64-bit DMA was first used, there were problems with the BCM4311 (14e4:4311). The problem was "fixed" by using the GFP_DMA flag in the allocation of coherent ring descriptor memory. The original problem is now believed to have been due to bugs in the 64-bit DMA implementation in the rest of the kernel, and that those bugs have been fixed. Accordingly, the requirement for the descriptors to be in the DMA zone is relaxed. Bounce buffers are left in the DMA zone. Signed-off-by:

Since commit e0626e38 (spi: prefix modalias with "spi:"), the spi modalias is prefixed with "spi:". This patch adds "spi:" prefix for modalias of stlc45xx. Also move it to be group with other modalias. Signed-off-by:

In order to implement support for GO powersave on the P2P client side, the ucode needs to know what GO we're trying to authenticate/associate with, it needs to have a station entry and the BSSID in the RXON set. Implement the new mac80211 callbacks to give this data to the device. Since this is also useful for the device when a normal connection is established, also program it with the information in that case. Signed-off-by:

priv->mac80211_registered and priv->hw needed to move to shared. stop_queue API was added in order to allow the upper layer to stop the SW queues for regulatory purposes. Signed-off-by:

Since all the check_empty logic is now in the transport layer, the upper layer doesn't need to know anything about tx queues. The disable aggregation flow was the last to know what a tx queue is, so move it too. Signed-off-by:

This logic is responsible to tell mac80211 when the HW queues are empty and the BA session can be started / torn down. Fix a bug on the way: When the the Tx BA session is stopped and the HW queues aren't empty, we stop the SW queue to drain the HW queue and then switch to the legacy HW queue. This is the IWL_EMPTYING_HW_QUEUE_DELBA state. While in this state, we never wake the SW queue, even when the HW queue is almost empty, since we need to drain it completely. Look at iwl_trans_pcie_reclaim regarding this. Once the HW queue is really empty, we must wake the SW queue in order to get traffic to the legacy queue. This step was missing leading to an odd situation were the traffic would just stall after we tore down a Tx BA session while the HW queue was not empty. Signed-off-by:

The queues and all the related logic suits to the transport layer. Signed-off-by:

This mapping is transport related. This allows us to remove the notion of tx queue from the tx path in the upper layer. iwl_wake_any_queue moved to transport layer since it needs to access these mappings. The TX API is nicer now: int (*tx)(struct iwl_trans *trans, struct sk_buff *skb, struct iwl_device_cmd *dev_cmd, u8 ctx, u8 sta_id); Signed-off-by:

In a near future, the upper layer won't be aware of the tx queues. This allows to remove one place where the upper layer needed to provide the tx queue index to the transport layer. This also saves around 1.5MB. Signed-off-by:

the mapping tx_queue -> fifo is really transport related. The upper layer should be involved in such things. Note that upon agg_disable, the queue is always mapped to fifo 0, but this doesn't matter since when the queue will be setup again for a new BA session, it will be configured to the good fifo anyway.

This removes the need for iwl_tx_info. Each tx queue holds an array of skbs, the transport layer doesn't need to know anything about the context in which a specific skb is sent. Signed-off-by:

When we remove the module, we free all the tx and rx resources. Before doing that, we'd better stop the tx / rx activity. Calling iwl_trans_stop_device in iwl_remove helps also to remove a few API functions: * rx_free: happens in iwl_trans_free * tx_free: happens in iwl_trans_free * disable_sync_irq: happens in iwl_trans_stop_device Signed-off-by:

There are still quite a few, but much less. A few fields have been moved /copied to hw_params which sits in the shared area: * priv->cfg->base_params->num_of_ampdu_queues * priv->cfg->base_params->shadow_reg_enable * priv->cfg->sku * priv->ucode_owner Signed-off-by:

The rate scaling and the transport need to access the data in iwl_tid_data, hence the move. Note that the only component in the upper layer that needs this data is the rate scaling. Refactoring the rate scaling may help to move iwl_tid_data from the shared area to the transport area. Signed-off-by:

Move all the iwlXXX_abgn_cfg forward declaration to a separate file so that iwl-pci.c doesn't need to include iwl-agn.h that includes all iwl-dev.h This allows to provide real encapsulation. Dereferencing iwl_priv in the bus layer will now lead to a compilation error. Signed-off-by:

Now that the reclaim flow has been moved to the transport layer, a lot of functions can be made static or don't need to be exported outside the transport layer. Signed-off-by:
-
Emmanuel Grumbach authored
The reclaim flow is really transport related. Define a simple API to allow the upper layer to request from the transport layer to reclaim packets until an index written in the Tx response / BA notification. The transport layer prepares a list of the packets that are being freed and passes this list to the upper layer. Between the two layers, the CB of the skb is used to pass a pointer to the context (BSS / PAN) in which the skb was sent. Signed-off-by:

It is accessed by the transport layer only, hence the move. The debugfs handlers that accessed it moved to the transport layer too. The rx_handlers part of it stayed in the upper layer and a special debugfs has been added for it Also add missing includes to iwl-commands.h. Signed-off-by:
