2025-01-13wifi: iwlwifi: rework firmware error handlingJohannes Berg
In order to later add the ability to do deeper resets of the device when it crashes, first restructure the firmware error handling. Instead of having just a single nic_error() method that handles all, split it: - nic_error() just handles and prints the error itself, - dump_error() synchronously creates an error dump, and - sw_reset() will be called to request doing a SW reset. This changes the architecture so that the transport is now responsible for deciding how to do the reset, and therefore the handling of reprobe if error occurs during reconfig moves there, which necessitates adding a method there that notifies the transport that the recovery was completed. Actually introducing the model under which deeper resets can be done will be in future patches.

2025-01-13wifi: iwlwifi: mvm: restart device through NMIJohannes Berg
When some channel context manipulations fail, the device is going to be restarted to try to recover. Make this go through a real FW restart via an NMI so the transport is aware of it and can later handle escalation, and to make it easier to restructure the code later.

2025-01-13wifi: iwlwifi: mvm: clean up FW restart a bitJohannes Berg
Approximately three years ago, in commit ddb6b76b6f96 ("iwlwifi: yoyo: support TLV-based firmware reset"), the code was (likely erroneously) changed to no longer treat error interrupts as firmware errors. As a result, this meant that the fw_restart counter was only applied in case of command queue being stuck, which never seems to happen. Also, there's no longer any way to set the mvm->fw_restart to a value that doesn't match exactly the module parameter behaviour. Instead of trying to fix this, simply remove the logic that limits the number of restarts, it's clearly unused. However, restore the logic that restart isn't unconditional, by checking the module parameter. Since the "fw_error" argument to iwl_mvm_nic_restart() is now always true (except in the "never happens" case of CMD queue stuck), just remove it too and treat command queue stuck the same way as everything else.

2025-01-13wifi: iwlwifi: differentiate NIC error typesJohannes Berg
Instead of differentiating only sync/async, differentiate the type of error, and document that only reset handshake timeout (IWL_ERR_TYPE_RESET_HS_TIMEOUT) needs sync handling. The special sync handling is somewhat temporary, the idea is to later split the nic_error() method into error dump, synchronizing the dump, and SW reset methods, and the type is mostly in order to unify command queue full handling into that new architecture as well.

2024-08-27wifi: iwlwifi: mvm: Offload RLC/SMPS functionality to firmwareDaniel Gabay
Currently, the driver handles SMPS decisions by tracking AP capabilities, BT coexistence changes, sending necessary SMPS frames to the AP, and updating firmware with RX chain info using the RLC_CONFIG_CMD. Starting with version 3 of the RLC_CONFIG_CMD, the firmware takes over this responsibility. It now tracks SMPS, sends frames, and configures the RLC. In this patch: 1. Stop sending RLC_CONFIG_CMD when firmware supports RLC offload (version 3), as rlc.rx_chain_info is not needed by firmware, and no other field in the cmd is used. 2. Prevent the driver from forwarding any SMPS requests to mac80211, i.e., the driver should not transmit SMPS frames to the AP as firmware handles that. 3. Set NL80211_FEATURE_DYNAMIC_SMPS and NL80211_FEATURE_STATIC_SMPS conditionally based on RLC version.

2024-08-26wifi: iwlwifi: mvm: fix hibernationEmmanuel Grumbach
Fast resume is a feature that was recently introduced to speed up the resume time. It basically keeps the firmware alive while the system is suspended and that avoids starting again the whole device. This flow can't work for hibernation, since when the system boots, before the frozen image is loaded, the kernel may touch the device. As a result, we can't assume the device is in the exact same state as before the hibernation. Detect that we are resuming from hibernation through the PCI device and forbid the fast resume flow. We also need to shut down the device cleanly when that happens. In addition, in case the device is power gated during S3, we won't be able to keep the device alive. Detect this situation with BE200 at least with the help of the CSR_FUNC_SCRATCH register and reset the device upon resume if it was power gated during S3.

iwl_mvm_get_bss_vif might return a NULL or ERR_PTR. Some of the callers check only the NULL case, and some doesn't check at all. Some of the callers even have a pointer to the mvmvif of the bss vif, so we don't even need to call this function, and can simply get the vif from mvmvif.

PLDR (product level device reset) is a Windows term, and is something the driver triggers there, AFAICT. Really what 'pldr_sync' here wants to capture is whether or not the firmware will/may do a product reset during initialization, which makes the device drop off the bus, requiring a rescan. If this is the case, obviously the init will fail/time out, so we don't want to report all kinds of errors etc., hence this tracking variable.

2024-05-06wifi: iwlwifi: mvm: Fix race in scan completionIlan Peer
The move of the scan complete notification handling to the wiphy worker introduced a race between scan complete notification and scan abort: - The wiphy lock is held, e.g., for rfkill handling etc. - Scan complete notification is received but not handled yet. - Scan abort is triggered, and scan abort is sent to the FW. Once the scan abort command is sent successfully, the flow synchronously waits for the scan complete notification. However, as the scan complete notification was already received but not processed yet, this hangs for a second and continues leaving the scan status in an inconsistent state. - Once scan complete handling is started (when the wiphy lock is not held) since the scan status is not an inconsistent state, a warning is issued and the scan complete notification is not handled. To fix this issue, switch back the scan complete notification to be asynchronously handling, and only move the link selection logic to a worker (which was the original reason for the move to use wiphy lock). While at it, refactor some prints to improve debug data.

2024-05-06wifi: iwlwifi: mvm: Block EMLSR when a p2p/softAP vif is activeYedidya Benshimol
When there's an active link in a non-station vif, the station vif is not allowed to enter EMLSR Note that blocking EMLSR by calling iwl_mvm_block_esr() we will schedule an exit from EMLSR worker, but the worker cannot run before the activation of the non-BSS link, as ieee80211_remain_on_channel already holds the wiphy mutex. Handle that by explicitly calling ieee80211_set_active_links() to leave EMLSR, and then doing iwl_mvm_block_esr() only for consistency and to avoid re-entering it before ready. Note that a call to ieee80211_set_active_links requires to release the mvm mutex, but that's ok since we still hold the wiphy lock. The only thing that might race here is the ESR_MODE_NOTIF, so this changes its handler to run under the wiphy lock.
