The firmware has different names for this, which is confusing as even the convention of having the firmware name in a comment after the struct definition wasn't met here. Fix the naming, but keep UATS in some of it since that's the BIOS name. Signed-off-by:

Firmware 0x2F7 assert observed in Dell platforms when using GL HW. This issue is mitigated by setting SCU_FORCE_ACTIVE during platform low power states. Driver shall indicate firmware to force SCU active by setting bit 29 in context info prph scratch control flags. This mitigation is limited to Dell platforms with GL HW only. Signed-off-by:

While doing a passive scan, the firmware will report per-channel survey information. This information is primarily useful for hostapd when doing an ACS (Automatic Channel Selection). Collect this information and add it to the result set when getting the survey information. Signed-off-by:

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. Fixes: 07bf5297 ("wifi: iwlwifi: mvm: Implement new link selection algorithm") Signed-off-by:

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. Signed-off-by:

If CSA is happening, then exit EMLSR to keep the better link, which is the primary link unless that's doing the CSA with quiet. This is done because we can't transmit the OMN frame on a quiet link, but want to exit EMLSR during CSA for better beacon reception, so we can follow the switch accurately. Signed-off-by:

The new link selection algorithm uses defaults values for BSS load if the BSS Load element was not published by the AP. For 6 GHz, that value is 0. So if the best link is 6 GHz, the EMLSR grade to always be equal to the grade of the best link, and then the best link grade is getting a bonus of 10 percent, meaning that we will never activate EMLSR. Change the logic to not give a bonus for the best link. Signed-off-by:

When non default TTLM is applied, mac80211 may force us to use a specific link (For example, if the only active link becomes a dormant link, mac80211 will pick the first usable link and set it as active). When default TTLM is applied, we have new usable links that we might want to select. Therefore, trigger MLO scan and link selection upon change in TTLM. Signed-off-by:

When an event occurs to unblock EMLSR, the code attempts to re-enable EMLSR. However, the current implementation always tries to activate EMLSR, regardless of whether the blocker was set before the unblocking event or not. If EMLSR was already unblocked, there is no need to re-activate it. Fixes: 6cf7df9f ("wifi: iwlwifi: mvm: Add helper functions to update EMLSR status") Signed-off-by:

EMLSR can't be activated from mac80211. Except for the debugfs, which is intended for testing purposes. Currently we don't allow entering EMLSR from debugfs if EMLSR is blocked, i.e. if mvmvif::esr_disable_reason is not 0. But we need a way to activate EMLSR regardless of the vif being blocked, for testing. Remove the check of esr_disable_reason Signed-off-by:

If the reason for exiting EMLSR was a blocking reason, wait for the corresponding unblocking event: - if there is an ongoing scan - do nothing. Link selection will be triggered at the end of it. - If more than 30 seconds passed since the exit, trigger MLO scan, which will trigger link selection - If less then 30 seconds passed since exit, reuse the latest link selection result If the reason for exiting EMLSR was an exit reason (IWL_MVM_EXIT_*), schedule MLO scan in 30 seconds.

BT Coex disables EMLSR only for a 2.4 GHz link, but doesn't block the vif from using EMLSR with a different link pair. In addition, storing it in mvmvif:disable_esr_reason requires extracting the BT Coex bit before checking if EMLSR is blocked or not for a specific vif. Therefore, change the BT Coex bit to be an exit reason and not a blocker. On link selection, EMLSR mode will be re-calculated for the 2.4 GHz link instead of checking that bit. While at it, move the relevant function declarations to the EMLSR functions area in mvm.h Signed-off-by:
