In a few PCIe devices we may have to swap out the configuration after we allocate/initialise some parts of the device because we only know the correct one after reading some registers. This causes some things such as the byte-count table allocations to be incorrect, since the configuration is swapped for one with a bigger queue size. Fix this by initialising most of the transport much later, only after the configuration has finally been determined. Signed-off-by:

It is not very useful to WARN if we can't send a host command The firmware is likely in a bad situation and the fact that we didn't send the host command has an impact on the firmware only, not on the driver. The driver could clean up all its state. Don't WARN in this case, but just leave a smaller note. Signed-off-by:

When we switch channel, we may miss a few beacons on the new channel. Don't disconnect if the time event for the switch ends before we hear the beacons. Note that this is relevant only for old devices that still use the TIME_EVENT firmware API for channel switch. The check that we hear a beacon before the time event ends was meant to be used for the association time event and not for the channel switch time event. Signed-off-by:

The only difference between iwl_pcie_napi_poll_msix_shared() and iwl_pcie_napi_poll_msix() is when we have a shared queue and nothing in the rx queue. This case doesn't affect CPU performance, so we can merge the two functions. Signed-off-by:

In case the device is stopped any usage of hw queues needs to be reallocated in fw due to fw reset after device stop, so all driver internal queue should also be freed, and if we don't free the next usage would leak the old memory and get in recover flows "iwlwifi 0000:00:03.0: dma_pool_destroy iwlwifi:bc" warning. Also warn about trying to reuse an internal allocated queue. Signed-off-by:

When doing scan while 6GHz channels are not enabled, the 6GHz band is not scanned. Thus, if there are no APs on the 2GHz and 5GHz bands (that will allow discovery of geographic location etc. that would allow enabling the 6GHz channels) but there are non collocated APs on 6GHz PSC channels these would never be discovered. To overcome this, FW added support for performing passive UHB scan in case no APs were discovered during scan on the 2GHz and 5GHz channels. Add support for enabling such scan when the following conditions are met: - 6GHz channels are supported but not enabled by regulatory. - Station interface is not associated or less than a defined time interval passed from the last resume or HW reset flows. - At least 4 channels are included in the scan request - The scan request includes the widlcard SSID. - At least 50 minutes passed from the last 6GHz passive scan.

When we do queue sync, it's confusing that we have the structures declared in the FW API header files that aren't really firmware, and the union is also confusing - especially now in the code that checks the size on the return. So rework this: change the type of sync and whether to do it in a synchronous fashion to arguments, and build the data structure in the function, so we don't need the union. Signed-off-by:

We use mvm->queue_sync_state to wait for synchronous queue sync messages, but if an async one happens inbetween we shouldn't clear mvm->queue_sync_state after sending the async one, that can run concurrently (at least from the CPU POV) with another synchronous queue sync. Signed-off-by:

If we (for example) have a trans_cfg entry in the PCI IDs table, but then don't find a full cfg entry for it in the info table, we fall through to the code that treats the PCI ID table entry as a full cfg entry. This obviously causes crashes later, e.g. when trying to build the firmware name string. Avoid such crashes by using the low bit of the pointer as a tag for trans_cfg entries (automatically using a macro that checks the type when assigning) and then checking that before trying to use the data as a full entry - if it's just a partial entry at that point, fail. Since we're adding some macro magic, also check that the type is in fact either struct iwl_cfg_trans_params or struct iwl_cfg, failing compilation ("initializer element is not constant") if it isn't.

For simplicity we assume that msix has 2 IRQ lines one used for rx data called msix_non_share, and another used for one bit flags messages (alive, hw error, sw error, rx data flag) called msix_share. Every time the FW has data to send it puts it on the RX queue and HW turns on the flags in msix_share (inta_fw) indicating about rx data, and HW sends an interrupt a bit later to the msix_non_share _unless_ the msix_shared RX data bit was cleared. Currently in the code every time we get an msix_shared we clear all bits including rx data queue bits. So we can have a race ---------------------------------------------------- DRIVER | HW | FW ---------------------------------------------------- - send host cmd to FW | | | | - handle message | | and put a response | | on the RX queue | - RX flag on | | | - send alive msix | - alive flag on | | - interrupt | | msix_share driver | - handle msix_shared | | and clear all flags | | bits | | | - don't send an | | interrupt on | | msix_non_shared | | (driver cleared) | - driver timeout on | | waiting for host cmd | | respond | | | | ---------------------------------------------------- The change is to clear only the msi_shared flags that are handled in the msix_shared flow, which will cause the hardware to send an interrupt on the msix_non_share line as well, when it has data.

"Fully associated" means that we heard a beacon with the DTIM information and the firmware is configured to track the beacons. Since the firmware needs to track the beacons for the CSA, we can't configure the firmware for CSA before it knows when the beacons are expected otherwise we'd get ASSERT 301D. If we are required to start CSA before we told the firmware when the beacons are expected to arrive, just report a failure and let mac80211 disconnect. Signed-off-by:

We currently have a special, separate, code path to acquire NIC access for the in-flight host-command workaround on 7000 series hardware. However, the normal code path here has grown a number of additional workarounds/semantics over time, such as reprobing the device if things fail. Rather than try to replicate any of this logic, call the normal grab_nic_access logic for the workaround. This changes the spinlock to _bh, but that's OK since it's just redundant, we already have soft-IRQs disabled when we get here, and so didn't (have to) do it again. Since it's only for commands there's however no point in making the code more complex just to not use _bh here. Signed-off-by:

When moving to the new channel, we block TX until we hear the first beacon. if it is not heard, we proceed to disconnect. Since TX is blocked (without mac80211 being aware of it) the frame is stuck, resulting with queue hang. Instead, reenable TX before reporting on the connection loss. As we are on the new channel, there is no problem with that, even if the original CSA had quiet mode. Signed-off-by:
