By reading the "driver_state" debugfs value we get all the important state information from the wl12xx driver. This helps testing and debugging, particularly in situations where the driver seems "stuck". Signed-off-by:

When operating as AP, the TX queues are not stopped when we start recovery. mac80211 is notified only after the fact. When there is pending TX, it will be queued even after the FW is down. This leads to situations where the TX queues are stopped (because of the TX-watermark mechanism), and are never woken up when we return from recovery. Fix this by explicitly stopping the TX queues when before initiating recovery. Signed-off-by:

Use the minimal rate configured in the basic rates set as the AP broadcast and multicast rate. The minimal rate is used to ensure weak links can still communicate. When the basic rates contains at least one OFDM rate, configure all unicast TX rates to OFDM only. Unify rate configuration on initialization and on change notification into a single function.

We use a long timeout (2 seconds) when sending commands to the FW. When a command times out, it means the FW is stuck, and we should commence recovery. This should make recovery times shorter as we'll recover on the first timeout indication. Signed-off-by:

Use the wiphy RTS and fragmentation thresholds for initializing the FW when possible. This mitigates a bug where previously set values are forgotten after interface down/up. Add checks before settings these values to ensure they are valid. Use default values when invalid thresholds are configured. Update the default RTS threshold to the maximum value given by the specification. Signed-off-by:

Frames are considered pending when they reside in the driver TX queue or already queued in the FW. This notion of "pending" is appropriate for power save considerations in STA mode, but not necessarily in other modes (for instance P2P-GO).

The FW can dynamically manage its internal TX & RX memory pools, moving blocks from one pool to another when necessary. This can significantly improve performance. Currently this feature is enabled only for 128x. Enable dynamic memory for 127x as well. Other parameters in the memory configuration structure may need to be fine tuned, as the optimal values for these may change once dynamic memory is enabled. Signed-off-by:

The driver stops sending TX packets when either there aren't enough memory blocks, or it runs out of TX descriptors. The driver continues to send packets to the FW only when more memory blocks are available. The FW might free TX descriptors without freeing the corresponding memory blocks, especially when dynamic memory is enabled. In cases where memory blocks are not freed at all, the driver will keep waiting for more memory blocks indefinitely. Fix this by clearing the WL1271_FLAG_FW_TX_BUSY flag when there are available TX descriptors. Signed-off-by:

The 128x/AP firmware does not yet support dynamic memory. Temporarily, the memory configuration for the 127x was used both for 127x/AP as well as 128x/AP. Since the two chips don't have the same number of memory blocks, TP was significantly degraded. This hasn't been fine tuned yet, but using the base 128x numbers (without dynamic memory) seems to yield much better results (around 30% more). Additional fine tuning will be required in the future.

ieee80211_reconfig() sets most of the "changed" flags regardless of the actual change (e.g. BSS_CHANGED_ASSOC will be set even if the interface is still not associated). in this case the driver will issue some unneeded commands. Since the driver relies solely on the BSS_CHANGED_ASSOC flag, without checking if there was an actual change, it will end up issuing unjoin() and dummy_join() commands, although it was never associated and should just remain idle. Avoid it by checking the actual state change, in addition to the "changed" flag. (there seem to be more redundant configuration commands being issued, but they shouldn't harm) Signed-off-by:

The elp_work is being enqueued on wl1271_ps_elp_sleep, but doesn't get cancelled on wl1271_ps_elp_wakeup. This might cause immediate entrance to elp when the wl->mutex is being released, rather than using the delayed enqueueing optimization. Cancel elp_work on wakeup request, and add a new WL1271_FLAG_ELP_REQUESTED flag to further synchronize the elp actions. [Fixed a couple of typos in some comments -- Luca] Signed-off-by:

The tx_headroom required for mwl8k driver is 32 bytes and it can use the space for 802.11 header received from mac80211. mwl8k considers the smallest 802.11 frame (CTS2self of 10 bytes) that can be received from mac80211 to compute the extra_tx_headroom as 22 (32 - 10) bytes. When the wireless interface is part of bridge, this extra_tx_headroom requirement results in a memcpy in mac80211 (in function pskb_expand_head) for all the data frames needing L2 forwarding/bridging, when NET_SKB_PAD is defined as 32. This patch reduces the extra_tx_headroom by 8 bytes so that memcpy of data frames in mac80211 is avoided in this case. The resize will be required in driver for frames with 802.11 header size of less than 18 bytes. Signed-off-by:

We mark command as huge by using meta->flags from other (non huge) command, but flags can be possibly overridden, when non huge command is enqueued, what can lead to: WARNING: at lib/dma-debug.c:696 dma_debug_device_change+0x1a3/0x1f0() DMA-API: device driver has pending DMA allocations while released from device [count=1] To fix introduce additional CMD_MAPPED to mark command as mapped and serialize iwl_enqueue_hcmd() with iwl_tx_cmd_complete() using hcmd_lock.
