wifi: iwlwifi: add support for a wiphy_work rx handler The wiphy_work infra ensures that the entire worker will run with the wiphy mutex. It is useful to have RX handlers running as a wiphy_work, when we don't want the handler to run in parallel with mac80211 work (to avoid races). For example - BT notification can disable eSR starting from the next patch. In ieee80211_set_active_links we first check that eSR is allowed, (drv_can_activate_links) and then activate it. If the BT notif was received after drv_can_activate_links (which returned true), and before the activation - eSR will be activated when it shouldn't. If BT notif is handled with the wiphy mutex, it can't run in parallel to ieee80211_set_active_links, which also holds that mutex. Add the necessary infrastructure here, for use in the next commit.

wifi: iwlwifi: mvm: fix regdb initialization In order to get regulatory domain, driver sends MCC_UPDATE_CMD to the FW. One of the parameters in the response is the status which can tell if the regdomain has changed or not. When iwl_mvm_init_mcc() is called during iwl_op_mode_mvm_start(), then sband is still NULL and channel parameters (i.e. chan->flags) cannot be initialized. When, further in the flow, iwl_mvm_update_mcc() is called during iwl_mvm_up(), it first checks if the regdomain has changed and then skips the update if it remains the same. But, since channel parameters weren't initialized yet, the update should be forced in this codepath. Fix that by adding a corresponding parameter to iwl_mvm_init_fw_regd().

So leave this as a member of iwl_mvm_vif, but add the link id to the time_event structure. The link id in time_event will only be maintained and used for: 1.

wifi: iwlwifi: mvm: Add basic link selection logic Add simple logic that would allow using EMLSR in case there are multiple valid links: - In case the connection establishment has just been completed try to find a valid link pair for EMLSR functionality where one of the links in the pair is the current active link. - In case the valid links changed after connection was already established, try to find a valid link pair for EMLSR functionality, in case the EMSLR is not active yet. If a valid link pair is found call mac80211 to asynchronously set the new link pair, otherwise continue using the current active links.

wifi: iwlwifi: mvm: add a per-link debugfs Add a per-link debugfs entry in iwlmvm level so we can read/write link related parameters. Do it by implementing the link_add_debugfs API introduced by mac80211. Each entry will have a path like this: .../netdev:wlan0/link-X/iwlmvm/<file_name> for each link X. For non-MLD vifs this callback is called when the original vif debugfs dir is also created, so handle that case by not creating the 'iwlmvm' directory again. Note that we don't have to worry about the cleaning the iwlmvm/* directory as it is already done by mac80211 when removing the link (or netdev).

wifi: iwlwifi: mvm: rework debugfs handling mac80211 added a new callback to add a vif debugfs. Implement it instead of adding the debugfs directly, which will make it properly preserved over switching the vif from non-MLD/MLD and back. This requires some rework so that we still have the symlink but trust mac80211 to add/remove the debugfs.

wifi: iwlwifi: mvm: support set_antenna() set_antenna() is supported only when the device is not started in mac80211 which translates to the firmware not being loaded in iwlwifi. The tricky part is that iwlwifi populates the sband data during its boot and doesn't touch this data afterwards, but if the antenna settings forbid MIMO, we need to update the sband data. Rework the nvm parsing code to allow to get an existing nvm_data and modify the sband with additional constraints (tx / rx chains masks).

wifi: iwlwifi: mvm: enable FILS DF Tx on non-PSC channel If the channel bandwidth is greater or equal than 80MHz, enable FILS DF transmittion, even if the control channel is non-PSC. That's because that in 80MHz there must be a sub 20MHz PSC channel, and since the FILS DF is duplicated on all sub 20MHz channels, within the 80MHz (hence it will be sent on a PSC channel). Also, if FILS DF Tx is enabled, always configure the firmware with the actual channel bandwidth, even before there is a connected client (rather than the minimum bandwidth e.g. 20MHz), since FILS DF transmission on a PSC channel take presedent over power consumption.

wifi: iwlwifi: remove 'use_tfh' config to fix crash This is equivalent to 'gen2', and it was always confusing to have two identical config entries. The split config patch actually had been originally developed after removing 'use_tfh" and didn't add the use_tfh in the new configs as they'd later been copied to the new files. Thus the easiest way to fix the init crash here now is to just remove use_tfh (which is erroneously unset in most of the configs now) and use 'gen2' in the code instead. There's possibly still an unwind error in iwl_txq_gen2_init() as it crashes if TXQ 0 fails to initialize, but we can deal with it later since the original failure is due to the use_tfh confusion.

wifi: iwlwifi: modify scan request and results when in link protection When CSME is connected and has link protection set, the driver must connect to the same AP CSME is connected to. When in link protection, modify scan request parameters to include only the channel of the AP CSME is connected to and scan for the same SSID. In addition, filter the scan results to include only results from the same AP. This will make sure the driver will connect to the same AP and will do it fast enough to keep the session alive.

wifi: iwlwifi: mvm: vif preparation for MLO In MLO, some fields of iwl_mvm_vif should be defined in the context of a link.

In this case, if the CSME takes ownership message arrives after the driver started unregistering, the iwl_mei_cache->ops is already invalid, so the host will not answer with the ownership confirmed message. Similarly, if the take ownership message arrived after the mac was stopped or when iwl_mvm_up() failed, setting rfkill will not trigger sending the confirm message. As a result, CSME will not take ownership, which will result in a disconnection. Fix it by sending the ownership confirmed message immediately in such cases.

wifi: iwlwifi: Track scan_cmd allocation size explicitly In preparation for reducing the use of ksize(), explicitly track the size of scan_cmd allocations. This also allows for noticing if the scan size changes unexpectedly. Note that using ksize() was already incorrect here, in the sense that ksize() would not match the actual allocation size, which would trigger future run-time allocation bounds checking. (In other words, memset() may know how large scan_cmd was allocated for, but ksize() will return the upper bounds of the actually allocated memory, causing a run-time warning about an overflow.)

iwlwifi: make iwl_fw_lookup_cmd_ver() take a cmd_id Instead of taking the group/command separately, make the function take a combined command ID. In many cases, this allows us to pass an existing command ID (e.g. cmd.id), or introduce a new variable for it, so that we don't use the command ID twice. This way, we can also use LONG_GROUP implicitly, so we don't need to spell that out for many commands. Apart from mvm.h, fw/img.{c,h} changes and some copyright and indentation updates, this was done with spatch: @@ identifier cmd; expression fw, G, C, def; @@ struct iwl_host_cmd cmd = { .id = WIDE_ID(G, C), ... }; ... -iwl_fw_lookup_cmd_ver(fw, G, C, def) +iwl_fw_lookup_cmd_ver(fw, cmd.id, def) @@ identifier cmd; expression fw, C, def; @@ struct iwl_host_cmd cmd = { .id = C, ... }; ... -iwl_fw_lookup_cmd_ver(fw, \(IWL_ALWAYS_LONG_GROUP\|LONG_GROUP\), C, def) +iwl_fw_lookup_cmd_ver(fw, cmd.id, def) @@ identifier func; expression fw, G, C, mvm, flags, cmd, size, def; type rettype; @@ rettype func(...) { +u32 cmd_id = WIDE_ID(G, C); ... -iwl_fw_lookup_cmd_ver(fw, G, C, def) +iwl_fw_lookup_cmd_ver(fw, cmd_id, def) ... -iwl_mvm_send_cmd_pdu(mvm, WIDE_ID(G, C), flags, cmd, size) +iwl_mvm_send_cmd_pdu(mvm, cmd_id, flags, cmd, size) ... } @@ identifier func; expression fw, G, C, mvm, flags, cmd, size, def; type rettype; @@ rettype func(...) { +u32 cmd_id = C; ... -iwl_fw_lookup_cmd_ver(fw, \(IWL_ALWAYS_LONG_GROUP\|LONG_GROUP\), C, def) +iwl_fw_lookup_cmd_ver(fw, cmd_id, def) ... -iwl_mvm_send_cmd_pdu(mvm, C, flags, cmd, size) +iwl_mvm_send_cmd_pdu(mvm, cmd_id, flags, cmd, size) ... } @@ expression fw, C, def; @@ -iwl_fw_lookup_cmd_ver(fw, \(IWL_ALWAYS_LONG_GROUP\|LONG_GROUP\), C, def) +iwl_fw_lookup_cmd_ver(fw, C, def) @@ expression fw, C, G, def; @@ -iwl_fw_lookup_cmd_ver(fw, G, C, def) +iwl_fw_lookup_cmd_ver(fw, WIDE_ID(G, C), def) Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Link: https://lore.kernel.org/r/iwlwifi.20220128153014.c4ac213cef5c.I6fd9a4fcbcf16ef3a3ae20a2b08ee54ebe06f96f@changeid Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

iwlwifi: mvm: don't feed the hardware RFKILL into iwlmei iwlmei can trigger a hardware RFKILL when the CSME firmware does not want the host to touch the device. But then, iwlmvm reports RFKILL which makes cfg80211 update iwlmvm about RFKILL. iwlmvm then thinks there is a change in the _software_ rfkill and it calls rfkill_blocked() to fetch the RFKILL state. This returns that RFKILL is blocked (because of iwlmei) and iwlmvm tells iwlmei that _software_ RFKILL is asserted. This is a bug of course. Fix this by checking explicitly the software RFKILL state and not the overall RFKILL state.

iwlwifi: mvm: retry init flow if failed In some very rare cases the init flow may fail. In many cases, this is recoverable, so we can retry. Implement a loop to retry two more times after the first attempt failed. This can happen in two different situations, namely during probe and during mac80211 start. For the first case, a simple loop is enough. For the second case, we need to add a flag to prevent mac80211 from trying to restart it as well, leaving full control with the driver.

iwlwifi: mvm: Add support for 6GHz passive scan 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.

iwlwifi: mvm: clean up queue sync implementation 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.

iwlwifi: mvm: simplify iwl_mvm_dbgfs_register No need to pass the dbgfs_dir just to assign it to mvm. Assign to mvm and then call iwl_mvm_dbgfs_register. This is a preparation towards the addition of a delayed op_mode_start flow. This will allow to split the op_mode_start flow. Registration to debugfs must happen after we register to mac80211 and the registration to mac80211 will soon be delayed in certain cases. In order not to have to remember the debugfs_dir in a separate variable, just set it into the mvm structure so that it can be usable later. Declare mvm->debugfs_dir in the iwl_mvm structure even when IWLWIFI_DEBUGFS isn't enabled to simplify the source code.

iwlwifi: mvm: add RFI-M support RF Interference Mitigation is a new feature targeted to handle the problem of interference between DDR memory and WiFi. The role of the driver is to configure FW with the table holding a mapping between problematic channels/bands and the corresponding frequencies. This patch adds RFI infrastructure and adds two debugfs hooks: - send RFI configuration command (currently with a default table) which will reset feature in the FW - read the table, used by the FW (which can be a subset of the table that driver sent).

Therefore, clear up any potential confusion and require that the data passed is of type struct iwl_mvm_internal_rxq_notif *.

iwlwifi: mvm: handle BAR_FRAME_RELEASE (0xc2) notification In prior hardware generations (e.g. 9000 series), we received the BAR frame with fake NSSN information to handle releasing frames from the reorder buffer for the default queue, the other queues were getting the FRAME_RELEASE notification in this case. With multi-TID block-ack, the firmware no longer sends us the BAR frame because the fake RX is quite big (just the metadata is around 48 bytes or so). Instead, it now sends us one (or multiple) special release notifications (0xc2). The hardware consumes these as well, but only generates the FRAME_RELEASE (0xc3) for queues other than the default queue. We thus need to handle them in the same way we handle the normal FRAME_RELEASE. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

iwlwifi: support per-platform antenna gain TX power limits as defined in the OTP assume the worst case scenario in terms of the platform's atenna gain, but most platforms are below that value so they can use more TX power without passing the regulatory limit. If the platform indicates in the BIOS that it indeed has lower gain, and the geographic location allows it, higher TX power can be used. The driver reads the PPAG (Per-Platform Antenna Gain) data from BIOS (if it exists), validates it and sends the appropriate command to the FW. This flow happens once at FW init, in case of suspend/resume there is no need to read again from BIOS as we save those values during init, so just send the PPAG command again to FW.

iwlwifi: mvm: add a loose synchronization of the NSSN across Rx queues In order to support MSI-X efficiently, we want to avoid communication across Rx queues. Each Rx queue should have all the data it needs to process a packet. The reordering buffer is a challenge in the MSI-X world since we can have a single BA session whose packets are directed to different queues. This is why each queue has its own reordering buffer. The hardware is able to hint the driver whether we have a hole or not, which allows the driver to know whether it can release a packet or not. This indication is called NSSN. Roughly, if the packet's SN is lower than the NSSN, we can release the packet to the stack. The NSSN is the SN of the newest packet received without any holes + 1. This is working as long as we don't have packets that we release because of a timeout. When that happens, we could have taken the decision to release a packet after we have been waiting for its predecessor for too long. If this predecessor comes later, we have to drop it because we can't release packets out of order. In that case, the hardware will give us an indication that we can we release the packet (SN < NSSN), but the packet still needs to be dropped. This is why we sometimes need to ignore the NSSN and we track the head_sn in software. Here is a specific example of this: 1) Rx queue 1 got packets: 480, 482, 483 2) We release 480 to to the stack and wait for 481 3) NSSN is now 481 4) The timeout expires 5) We release 482 and 483, NSSN is still 480 6) 481 arrives its NSSN is 484. We need to drop 481 even if 481 < 484. This is why we'll update the head_sn to 484 at step 2. The flow now is: 1) Rx queue 1 got packets: 480, 482, 483 2) We release 480 to to the stack and wait for 481 3) NSSN is now 481 / head_sn is 481 4) The timeout expires 5) We release 482 and 483, NSSN is still 480 but head_sn is 484. 6) 481 arrives its NSSN is 484, but head_sn is 484 and we drop it. This code introduces another problem in case all the traffic goes well (no hole, no timeout): Rx queue 1: 0 -> 483 (head_sn = 484) Rx queue 2: 501 -> 4095 (head_sn = 0) Rx queue 2: 0 -> 480 (head_sn = 481) Rx queue 1: 481 but head_sn = 484 and we drop it. At this point, the SN of queue 1 is far behind: more than 4040 packets behind. Queue 1 will consider 481 "old" because 481 is in [501-64:501] whereas it is a very new packet. In order to fix that, send an Rx notification from time to time (twice across the full set of 4096 packets) to make sure no Rx queue is lagging too far behind. What will happen then is: Rx queue 1: 0 -> 483 (head_sn = 484) Rx queue 2: 501 -> 2047 (head_sn = 2048) Rx queue 1: Sync nofication (head_sn = 2048) Rx queue 2: 2048 -> 4095 (head_sn = 0) Rx queue 1: Sync notification (head_sn = 0) Rx queue 2: 1 -> 481 (head_sn = 482) Rx queue 1: 481 and head_sn = 0. In queue 1's data, head_sn is now 0, the packet coming in is 481, it'll understand that the new packet is new and it won't be dropped.

iwlwifi: mvm: delay GTK setting in FW in AP mode In AP (and IBSS) mode, we can only set GTKs to firmware after we have sent down the multicast station, but this we can only do after we've enabled beaconing, etc. However, during rfkill exit, hostapd will configure the keys before starting the AP, and cfg80211/mac80211 accept it happily. On earlier devices, this didn't bother us as GTK TX wasn't really handled in firmware, we just put the key material into the TX cmd and thus it only mattered when we actually transmitted a frame. On newer devices, however, the firmware needs to track all of this and that doesn't work if we add the key before the (multicast) sta it belongs to. To fix this, keep a list of keys to add during AP enable, and call the function there.

iwlwifi: mvm: use dump worker during restart instead of sync dump In restart flow, the driver requests HW restart from mac80211 and then mac80211 uses a worker to do the restart flow. In that flow a sync dump is performed. Instead, schedule the dump worker before requesting HW restart from mac80211. This approach simplifies the restart flow. Also, it is neeeded in order to differentiate between the handling of SW and HW errors in a future commit.

iwlwifi: mvm: fix TX crypto on 22560+ devices In the old days, we could transmit with HW crypto with an arbitrary key by filling it into TX_CMD. This was broken first with the advent of CCMP/GCMP-256 keys which don't fit there. This was broken *again* with the newer TX_CMD format on 22560+, where we simply cannot pass key material anymore. However, we forgot to update all the cases when we get a key from mac80211 and don't program it into the hardware but still return 0 for HW crypto on TX. In AP mode with WEP, we tried to fix this by programming the keys separately for each station later, but this ultimately turns out to be buggy, for example now it leaks memory when we have more than one WEP key. Fix this by simply using only SW crypto for WEP in newer devices by returning -EOPNOTSUPP instead of trying to program WEP keys later.

iwlwifi: mvm: add support for 32kHz external clock indication In low power modes, the chip clock source for platform integrated devices is 32kHz. It is generated internally and supplied by a crystal oscillator. However using a 32kHz sourced from crystal oscillator has high power penalty. There is an option to get an external 32kHz clock from the platform. Past experience shows that the reliability is platform dependent, i.e. on some platforms it works good and on other it doesn’t. Working from external clock will save 0.5 mW in sleep state, from overall 1.8mW that we have today, i.e. almost 30%. Each OEM can enable or disable the use of the external 32kHz clock by setting a BIOS configuration. In case the OEM configured to use 32kHz external clock the driver will pass this indication to the FW.

Prior to setting the device up, ieee80211_reconfig does not call iwl_mvm_mac_start since there is nothing to reconfig and we miss the dump collection of the assert. solve it by checking the restart bit before we stop the device and trigger a dump collection in case it is set. note that we don't need to do it in the fmac case since in fmac assert flow in iwl_fmac_nic_error we call iwl_fw_dbg_collect_desc so we can be sure that there will a dump collection in iwl_fmac_stop_device.

iwlwifi: mvm: get rid of tx_path_lock TX path lock was introduced in order to prevent out of order invocations of TX. This can happen in the following flow: TX path invoked from net dev Packet dequeued TX path invoked from RX path Packet dequeued Packet TXed Packet TXed However, we don't really need a lock. If TX path is already invoked from some location, other paths can simply abort their execution, instead of waiting to the first path to finish, and then discover queue is (likely) empty or stopped. Replace the lock with an atomic variable to track TX ownership. This simplifies the locking dependencies between RX and TX paths, and should improve performance.

iwlwifi: mvm: support mac80211 TXQs model Move to use the new mac80211 TXQs implementation. This has quite a few benefits for us. We can get rid of the awkward mapping of DQA to mac80211 queues. We can stop buffering traffic while waiting for the queue to be allocated. We can also use mac80211 AMSDUs instead of building it ourselves. The usage is pretty simple: Each ieee80211_txq contains iwl_mvm_txq. There is such a queue for each TID, and one for management frames. We keep having static AP queues for probes and non-bufferable MMPDUs, along with broadcast and multicast queues. Those are being used from the "old" TX invocation path - iwl_mvm_mac_tx. When there is a new frame in a TXQ, iwl_mvm_mac_wake_tx is being called, and either invokes the TX path, or allocates the queue if it does not exist. Most of the TX path is left untouched, although we can consider cleaning it up some more, for example get rid of the duplication of txq_id in both iwl_mvm_txq and iwl_mvm_dqa_txq_info.

iwlwifi: mvm: kill INACTIVE queue state We don't really need this state: instead of having an inactive state where we can awaken zombie queues again if needed, just keep them in their normal state unless a new queue is actually needed and there's no other way of getting one. We do this here by making the inactivity check not free queues unless instructed that we now really need to allocate one to a specific station, and in that case it'll just free the queue immediately, without doing any inactivity step inbetween. The only downside is a little bit more processing in this case, but the code complexity is lower. Additionally, this fixes a corner case: due to the way the code worked, we could only ever reuse an inactive queue if it was the reserved queue for a station, as iwl_mvm_find_free_queue() would never consider returning an inactive queue.

Additionally, the queue that became RECONFIGURING would've been in SHARED state before, and it can safely stay in that state. In case of errors, it previously would have stayed in RECONFIGURING which it could never have left again.

iwlwifi: mvm: add NOA and CSA to a probe response A probe response built by a P2P GO should contain: 1. CSA/eCSA IE when relevant 2. If the corresponding probe request had P2P IE, then need to add P2P IE with NOA attributes. However, the NOA attributes and the updated channel switch counter are known only to the FW. The solution is that FW will send a notification with the relevant probe response data and the driver will save it and update the probe response accordingly.

iwlwifi: mvm: support new WoWLAN status FW API A new FW API has been added for WOWLAN_GET_STATUSES to support multiple GTK keys and IGTK keys. Check the respective TLV and use the new API when it is set. Let most of the code use the new version (v7) and convert the old version (v6) to the new one when needed. Also refactor some functions a bit so that they can be reused more easily. Particularly the part that calls WOWLAN_GET_STATUSES which is reused in D3 and D0i3.

iwlwifi: mvm: Increase session protection time after CS After switching to a new channel, driver schedules session protection time event in order to hear the beacon on the new channel. The duration of the protection is two beacon intervals. However, since we start to switch slightly before beacon with count 1, in case we don't hear (or AP doesn't transmit) the very first beacon on the new channel the protection ends without hearing any beacon at all. At this stage the switch is not complete, the queues are closed and the interface doesn't have quota yet or TBTT events. As the result, we are stuck forever waiting for iwl_mvm_post_channel_switch() to be called. Fix this by increasing the protection time to be 3 beacon intervals and in addition drop the connection if the time event ends before we got any beacon.

This of course has no implication on the channel width but still sends a command to the firmware. Remember the last width that was sent and refrain from sending unnecessary commands to the firmware.

We observed the following situation: * mac80211 is in authentication flow, in ieee80211_prep_connection() * iwlwifi firmware crashes, but no error can be reported at this precise point (mostly because the driver method is void, but even if it wasn't we'd just shift to a race condition) * mac80211 continues the flow, trying to add the AP station * iwlwifi has already set its internal restart flag, and so thinks that adding the station is part of the restart and already set up, so it uses the information that's supposed to already be in the struct This can happen with any flow in mac80211 and with any information we try to preserve across hardware restarts. To fix this, only set a new HW_RESTART_REQUESTED flag and translate that to IN_HW_RESTART once mac80211 actually starts the restart by calling our start() method. As a consequence, any mac80211 flow in progress at the time of the restart will properly finish (certainly with errors), before the restart is attempted. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195299.

iwlwifi: mvm: fix mac80211 queue tracking In the driver, we track which hardware queue is associated with which mac80211 "hw_queue", in order to be able to stop and wake it. When moving these bitmaps out of the queue_info structures, the type of the bitmap was erroneously changed from u32 to u8, presumably in order to save memory. Turns out that u32 isn't needed, because the highest queue we can ever tell mac80211 is always < 16, but a u16 definitely is needed, queues >=8 do happen. While at it, throw a BUILD_BUG_ON() into the place where we set the limit (mvm->first_agg_queue) and a warning when it actually gets put into the bitmap. The consequence of this bug is that full HW queues associated with such a too-high mac80211 number never stop higher layer queues when full, and thus would simply drop all packets that couldn't be enqueued to the hardware queue.

iwlwifi: add a W/A for a scheduler hardware bug In case we need to move the scheduler write pointer by steps of 0x40, 0x80 or 0xc0, the scheduler gets stuck. This leads to hardware error interrupts with status: 0x5A5A5A5A or alike. In order to work around this, detect in the transport layer that we are going to hit this case and tell iwlmvm to increment the sequence number of the packets. This allows to keep the requirement that the WiFi sequence number is in sync with the index in the scheduler Tx queue and it also allows to avoid the problematic sequence. This means that from time to time, we will start a queue from ssn + 1, but that shouldn't be a problem since we don't switch to new queues for AMPDU now that we have DQA which allows to keep the same queue while toggling the AMPDU state.

Change the flow as following: * read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL) * clear those registers * wait for the hardware to complete its write to the buffer * get the data * restore the value of those registers (to restart the recording) For early start (where the configuration is already compiled in the firmware), we don't need to set those registers after the firmware has been loaded, but only when we want to restart the recording without having restarted the firmware.

iwlwifi: mvm: add multicast station Currently multicast queue is associated with the broadcast station. This raises quite a few issues: The multicast queue has a special treatment: - It is sent in the MAC context command - It is excluded from tfd_queue_mask In DQA mode we end up enabling two queues - the probe response queue and the multicast queue - with the same station (broadcast) and TID while in DQA mode it should be unique RA-TID. Firmware will enforce it for a000 devices, so this allocation will fail. In addition, in a000 devices the FW will set the FIFO and not the driver. So there is a need for FW to know when we enable the queue that it is multicast queue so it will be bound to the multicast FIFO. There is no such way in current design. In order to simplify driver and firmware handling of this queue create a multicast station. This solves the unique RA-TID issue in the short term and serves as preparation for the long term. In the long term we will also add a flag marking this station for the FW as the multicast station. Once we will do that the FW will know this is the multicast queue immediately when it is added and bind it to the correct FIFO. It will also enable removing the special treatment of the queue in the MAC context command. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

INIT complete will now follow the NVM access command, without phy DB calls before. * Paging command is sent earlier in the flow before NVM access to enable a complete load of FW. * caution must be care when restart is called since we may have not completed init flow even though we are in RT firmware.

This allows an AP to send, for instance, BE traffic to STA2 even if it also needs to send traffic to a sleeping STA1, without being blocked by the sleeping station. The implementation in the driver is now ready, so we can enable this feature by default when running firmwares that support it.

iwlwifi: mvm: use firmware station PM notification for AP_LINK_PS When using RSS on 9000 series devices, we can't rely on processing the received frames for station powersave handling, since they could be processed on different CPUs and out of order. In order to still manage the powersave of stations, the firmware sends a notification on sleep->wake, wake->sleep and - for U-APSD - frames received with PM while already sleeping (with the TID.) With this, the driver can set AP_LINK_PS, which is required for real parallel RX. In addition, this requires checking for PS-Poll frames and calling ieee80211_sta_pspoll() appropriately.

iwlwifi: mvm: wake the wait queue when the RX sync counter is zero When we sync the RX queues the driver waits to receive echo notification on all the RX queues. The wait queue is set with timeout until all queues have received the notification. However, iwl_mvm_rx_queue_notif() never woke up the wait queue, with the result of the counter value being checked only when the timeout expired. This may cause a latency of up to 1 second.

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.

iwlwifi: mvm: add reorder timeout per frame Add a timer in order to release expired frames from the reorder buffer. This is needed since some APs do not retransmit frames to fill in the reorder holes and in TCP it results with a complete stall of traffic. This has a few side effects on the general design: The nssn may not reflect the the head of the reorder buffer. This situation is valid, and packets with SN lower than the reorder buffer head will be dropped. Another side effect is that since the reorder timer might expire we need to lock the reorder buffer. This however is fine since the locking is only inside a single reorder buffer between RX path and reorder timeout and there is no outside contention.

iwlwifi: mvm: add reorder buffer per queue Next hardware will direct packets to core based on the TCP/UDP streams. This logic can create holes in reorder buffer since packets that belong to other stream were directed to a different core. However, those are valid holes and the packets can be indicated in L3 order. The hardware will utilize a mechanism of informing the driver of the normalized ssn and the driver shall release all packets that SN is lower than the nssn. This enables managing the reorder across the queues without sharing any data between them. The reorder buffer is allocated and released directly in the RX path in order to avoid various races between control path and rx path. The code utilizes the internal messaging to notify rx queues of when to delete the reorder buffer.

iwlwifi: mvm: support bss dynamic alloc/dealloc of queues "DQA" is shorthand for "dynamic queue allocation". This enables on-demand allocation of queues per RA/TID rather than statically allocating per vif, thus allowing a potential benefit of various factors. Please refer to the DOC section this patch adds to sta.h to see a more in-depth explanation of this feature. There are many things to take into consideration when working in DQA mode, and this patch is only one in a series. Note that default operation mode is non-DQA mode, unless the FW indicates that it supports DQA mode. This patch enables support of DQA for a station connected to an AP, and works in a non-aggregated mode. When a frame for an unused RA/TID arrives at the driver, it isn't TXed immediately, but deferred first until a suitable queue is first allocated for it, and then TXed by a worker that both allocates the queues and TXes deferred traffic. When a STA is removed, its queues goes back into the queue pools for reuse as needed.

The driver issues a request to the firmware that includes the duration of the measurement (the firmware needs to be on channel for that amount of time) and the timeout (in case the firmware has a lot of offchannel activities). If the timeout elapses, the firmware will send partial results which are still valuable. In case of disassociation / channel switch and alike, the driver is in charge of stopping the measurements and the firmware will reply with partial results.

iwlwifi: mvm: add RSS queues notification infrastructure In multi rx queue HW, without execessive locking, there is no sync between the ctrl path (default queue) and the rest of the rx queues. This might cause issues on certain situations. For example, in case a delBA was processed on a default queue but out of order packets still wait for processing on the other queue. The solution is to introduce internal messaging between the CTRL path and the other rx queues. The driver will send a message to the firmware, which will echo it to all the requested queues. The message will be in order inside the queue. This way we can avoid CTRL path and RSS queues races. Add support for this messaging mechanism. As the firmware is agnostic to the data sent, add internal representation of the data as well. Although currently only delBA flow will use it, the internal representation will enable generic use of this infrastructure for future uses. Next patch will utilize this messaging mechanism for the reorder buffer delBA flow. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

iwlwifi: mvm: handle pass all scan reporting The firmware doesn't send match found notifications when no matchsets are passed. This makes sense because if there are no matchsets, nothing can be matched. But the nl80211 API should report when there are results available, even if no matchsets were passed. To handle this, we can use the firmware's ITERATION_COMPLETE reporting, which will send us notifications every time it completed a scheduled scan iteration. Then we can set a flag when we received beacons and use that to report that results are available.

iwlwifi: mvm: change protocol offload flows RFC4862 states that "In all cases, a node MUST NOT respond to a Neighbor Solicitation for a tentative address". Currently the driver configures the NS offload and does not wait for address to become permanent, thus violating the RFC. Just removing the address from the address list is not good enough for all cases, since the NS messages are needed for the duplicate address detection and should not be discarded. For d0i3 disable NS offload. Put tentative address in the address list so the NS packet will not be filtered out by ucode. For D3 the platform will not wake from NS packets - so enable NS offload while removing the tentative address from the list. Given that now NS offload might be disabled, and that the ucode uses the IP data for other puroposes (L3 filtering) add two independent flags indicating if IPv4\IPv6 data is valid.

iwlwifi: replace d0i3_mode and wowlan_d0i3 with more generic variables The d0i3_mode variable is used to distinguish between transports that handle d0i3 entry during suspend by themselves (i.e. the slave transports) and those which rely on the op_mode layer to do it. The reason why the former do it by themselves is that they need to transition from d0i3 in runtime_suspend into d0i3 in system-wide suspend and this transition needs to happen before the op_mode's suspend flow is called. The wowlan_d0i3 element is also a bit confusing, because it just reflects the wowlan->any value for the trans to understand. This is a bit unclear in the code and not generic enough for future use. To make it clearer and to generalize the platform power mode settings, introduce two variables to indicate the platform power management modes used by the transport. Additionally, in order not to take too big a step in one patch, treat this new variables semantically in the same way as the old d0i3_mode element, introducing a iwl_mvm_enter_d0i3_on_suspend() function to help with that. This commit also adds the foundation for a new concept where the firmware configuration state (i.e. D0, D3 or D0i3) is abstracted from the platform PM mode we are in (i.e. runtime suspend or system-wide suspend).
