2024-05-06wifi: iwlwifi: mvm: Block EMLSR when a p2p/softAP vif is activeYedidya Benshimol7-19/+133
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.

2024-05-06wifi: iwlwifi: mvm: avoid always prefering single-linkMiri Korenblit1-2/+2
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.

2024-05-04wifi: rtw89: wow: refine WoWLAN flows of HCI interrupts and low power modeChih-Kang Chang2-3/+12
After enabling packet offload, the TX will be stuck after resume from WoWLAN mode. And the 8852c gets error messages like rtw89_8852ce 0000:04:00.0: No busy txwd pages available rtw89_8852ce 0000:04:00.0: queue 0 txwd 100 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 101 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 102 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 103 is not idle If suspend/resume many times that firmware will download failed and disconnection. To fix these issues, We removed the rtw89_hci_disable_intr() and rtw89_hci_enable_intr() during rtw89_wow_swap_fw() to prevent add packet offload can't receive c2h back due to interrupt disable. Only 8852C and 8922A needs to disable interrupt before downloading fw. Furthermore, we avoid using low power HCI mode on WoWLAN mode, to prevent interrupt enabled, then get interrupt and calculate RXBD mismatched due to software RXBD index already reset but hardware RXBD index not yet.

2024-05-03wifi: iwlwifi: pcie: allocate dummy net_device dynamicallyBreno Leitao3-13/+27
struct net_device shouldn't be embedded into any structure, instead, the owner should use the priv space to embed their state into net_device. Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from struct iwl_trans_pcie by converting it into a pointer. Then use the leverage alloc_netdev() to allocate the net_device object at iwl_trans_pcie_alloc. The private data of net_device becomes a pointer for the struct iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent given the net_device object.

Before request->channels[] can be used, request->n_channels must be set. Additionally, address calculations for memory after the "channels" array need to be calculated from the allocation base ("request") rather than via the first "out of bounds" index of "channels", otherwise run-time bounds checking will throw a warning.
