Since all the irq / tasklet is now handled in the transport layer, it should give an API to ensure that all the irq / tasklet have finished running. This will allow the upper layer to release all its resources. Signed-off-by:

WiFi throughput drops drastically when BT is turned on, BT and WiFi are simultaneously transmitting/receiving traffic. This is particularly true when BT has higher priority over WiFi, and hence the device defers TX frames. The AP assumes that the channel is bad and reduces the data rate, implying longer airtime, which exacerbates the problem further, resulting ultimately in what is popularly called the "death-spiral" phenomenon. The use of PS-poll in such scenarios guarantees a low but consistent throughput. Since the death-spiral phenomenon is observed only when the RSSI is low, use PS-poll only when RSSI is low and disable when high, with a known hysterisis. This feature specifies the high and low thresholds and implements the callbacks registered with mac80211, which will be called when threshold events occur. iwlwifi: dynamic pspoll: optimize rssi monitor code Signed-off-by:

Now, there are only two functions to send a host command: * send_cmd that receives a iwl_host_cmd * send_cmd_pdu that builds the iwl_host_cmd itself and received flags The flags CMD_ASYNC / CMD_SYNC / CMD_WANT_SKB are not changed by the API functions. Kill the unused flags CMD_SIZE_NORMAL / CMD_NO_SKB on the way. Signed-off-by:

Bus specific layer must know how to return the struct device* of the device. Implement that as a callback of iwl_bus_ops and use that callback instead of using the priv->pdev pointer which is meant to disappear soon. Since the struct device * is needed in hot path, iwl_bus holds a pointer to it instead of calling get_dev all the time. Signed-off-by:

The current "huge" command handling is a bit confusing, and very limited since only one command may be huge at a time. Additionally, we often copy data around quite pointlessly since we could instead map the existing scan buffer for example and use it directly. This patch makes that possible. The first change is that multiple buffers may be given to each command (this change was prepared earlier so callsites don't need to change). Each of those can be mapped attached to a TB in the TFD, and the command header can use a TB (the first one) in the TFD as well. Doing this allows getting rid of huge commands in favour of mapping existing buffers. The beacon transmission is also optimised to not copy the SKB at all but use multiple TBs. Signed-off-by:

In a subsequent patch, I want to make commands use multiple TBs in a TFD. This is a simple change to prepare the data structures for this, with as of now still just a single TB supported. Signed-off-by:

New microcode versions use the good CRC threshold field differently, as a flag, and in that case we should set it to 1/0 instead of 1/65535 for an active/passive scan. The new behaviour is advertised by the uCode with a feature flag. Signed-off-by:

If a device error happens while the uCode is being loaded or initialised, we will attempt to restart the device (which will likely fail again, but that's not the issue here). During this new restart, we turn off the device, but as the uCode failed to initialise it already is turned off. As a consequence, grabbing NIC access will fail and cause excessive messages and hangs. To fix this issue, introduce a new status bit and only attempt to reprogram the device when it isn't already disabled. Signed-off-by:

The current firmware loading mechanism in iwlwifi is very hard to follow, and thus hard to maintain. To make it easier, make the firmware loading synchronous. For now, as a side effect, this removes a number of retry possibilities we had. It isn't typical for this to fail, but if it does happen we restart from scratch which this also makes easier to do should it be necessary. Signed-off-by:

When the firmware encounters an error while the driver is waiting for a notification, it will never get that notification. Therefore, instead of timing out, bail out on errors when waiting for notifications. Signed-off-by:

We're unlikely to care about the actual time spent waiting, so make the function return an error code which is less error prone in coding new uses. Also, while at it, mark __must_check. Signed-off-by:

There's no need to keep both normal and BT statistics versions around all the time in memory when we only use a subset of both. So keep only the subsets that we need in memory, depending on the debug config). Also, in doing so, we can remove all the calls to iwl_bt_statistics() in the driver as we'll just access the copied statistics now. Finally, also remove this call from the one place where it might still be needed and automatically detect what kind of statistics the device is sending based on their size. This way, we don't need to keep track of which devices do what any more, which is good since this is subject to change based on the ucode version (as some ucode even for non-BT devices will in fact use BT statistics). Warn upon encountering a statistics command from the ucode that isn't known, so we will find such issues earlier in the future. Signed-off-by:
