2025-10-30wifi: ath12k: Add EHT MCS/NSS rates to Peer AssocMuna Sinada
Add EHT MCS/NSS rate functionality to peer association. As part of ath12k_peer_assoc_h_eht() add the calculation of EHT MCS/NSS using intersection of link_sta and phy capability. ath12k_mac_max_eht_mcs_nss() function is utilized when comparing the max NSS of link STA and phy capability since in split phy case, phy supports max NSS of 2 for 5G band.

Currently, functions in mac.c for setting GI and LTF rates are specifically for HE rates. Remove any mention of "HE" in such functions in order to allow for other modes to utilize the functions. The intention is to prepare for the addition of EHT GI and LTF fixed rate settings.

2025-10-30wifi: ath12k: fix error handling in creating hardware groupBaochen Qiang
In ath12k_core_init() when ath12k_core_hw_group_create() fails, ath12k_core_hw_group_destroy() is called where for each device below path would get executed ath12k_core_soc_destroy() ath12k_qmi_deinit_service() qmi_handle_release() This results in kernel crash in case one of the device fails at qmi_handle_init() when creating hardware group: ath12k_pci 0000:10:00.0: failed to initialize qmi handle ath12k_pci 0000:10:00.0: failed to initialize qmi :-517 ath12k_pci 0000:10:00.0: failed to create soc core: -517 ath12k_pci 0000:10:00.0: unable to create hw group BUG: unable to handle page fault for address: ffffffffffffffb7 RIP: 0010:qmi_handle_release Call Trace: <TASK> ath12k_qmi_deinit_service ath12k_core_hw_group_destroy ath12k_core_init ath12k_pci_probe The detailed reason is, when qmi_handle_init() fails for a device ab->qmi.handle is not correctly initialized. Then ath12k_core_hw_group_create() returns failure, since error handing is done for all device, eventually qmi_handle_release() is called for the issue device and finally kernel crashes due to the uninitialized ab->qmi.handle. Fix this by moving error handling to ath12k_core_hw_group_create(), this way the issue device can be skipped.

2025-10-30wifi: ath12k: fix reusing m3 memoryBaochen Qiang
During firmware recovery or suspend/resume, m3 memory could be reused if the size of the new m3 binary is equal to or less than that of the existing memory. There will be issues for the latter case, since m3_mem->size will be updated with a smaller value and this value is eventually used in the free path, where the original total size should be used instead. To fix it, add a new member in m3_mem_region structure to track the original memory size and use it in free path.

2025-10-28wifi: iwlwifi: mld: reschedule check_tpt_wk also not in EMLSRMiri Korenblit
When the throughput count reaches the threshold, EMLSR is no longer blocked by throughput. This doesn't mean that EMLSR will be activated immediately, since there might be other reasons that block EMLSR. When the throughput blocker is not set, check_tpt_wk should run every 5 seconds and check if the throughput blocker should be set (if the throughtput counter dropped). If not, it should reschedule itself. In the current code, the worker will reschedule itself only if we are in EMLSR. This is wrong, since we might be in a case where the throughput blocker is not set but we are not in EMLSR, and then we will never check again the throughput counters (and block EMLSR if needed). Fix this by rescheduling the worker also when EMLSR is not active.

2025-10-27wifi: ath12k: Use ath12k_dp_peer in per packet Tx & Rx pathsHarsh Kumar Bijlani
Move link agnostic data path parameters (keys, rx_tid, reorder buffers, MIC context etc) from ath12k_sta and ath12k_dp_link_peer into ath12k_dp_peer. These parameters are shared across MLO links and should be managed at the peer level. Configure them only when the link peer is primary to avoid redundancy and ensure consistent setup. Switch per-packet Tx/Rx paths and monitor paths to look up ath12k_dp_peer and ath12k_dp_link_peer via peer_id. Helper APIs added: - ath12k_dp_peer_find_by_peerid() - ath12k_dp_link_peer_find_by_peerid() Ensure RCU read lock is held when using these helpers APIs. With the above API ath12k_dp_link_peer_find_by_peerid() being used to find ath12k_dp_link_peer, existing API ath12k_dp_link_peer_find_by_id() is required only at the time of unmap event from firmware since it fetches the ath12k_dp_link_peer from linked list. In order to restrict the usage of API ath12k_dp_link_peer_find_by_id(), make it static and also rename it to ath12k_dp_link_peer_search_by_id().

2025-10-27wifi: ath12k: Attach and detach ath12k_dp_link_peer to ath12k_dp_peerHarsh Kumar Bijlani
Introduce explicit attach/detach of ath12k_dp_link_peer objects to their parent ath12k_dp_peer to formalize the data path station hierarchy: ath12k_dp_peer | |--> ath12k_dp_link_peer | |--> ath12k_dp_link_peer | |--> ath12k_dp_link_peer ath12k_dp_peer maintains an array of RCU-protected pointers "link_peers[ATH12K_NUM_MAX_LINKS]" to ath12k_dp_link_peer indexed by its protocol_link_id, and each ath12k_dp_link_peer holds a back pointer to its parent ath12k_dp_peer. Attach is performed after link peer creation, and detach occurs before link peer deletion. This ensures consistent lifetime management and safe concurrent access. ath12k_dp_peer also maintains an array "hw_links[ATH12K_GROUP_MAX_RADIO]" to store the mapping between hw_link_id and protocol_link_id for each of the ath12k_dp_link_peer. RCU locking/unlocking rules: - Readers must hold rcu_read_lock() and fetch the pointer with rcu_dereference(dp_peer->link[link_id]); drop with rcu_read_unlock() when done. - Writers publish with rcu_assign_pointer() and reclaim only after synchronize_rcu(). Handle the case of detachment of link peer from ath12k_dp_peer in case of core reset.

2025-10-27wifi: ath12k: Define ath12k_dp_peer structure & APIs for create & deleteHarsh Kumar Bijlani
Define the structure of ath12k_dp_peer and also define APIs for creation and deletion of ath12k_dp_peer based on STA state, as the ath12k_dp_peer is intended to be used in the subsequent set of patches. Maintain ath12k_dp_peer in a linked list in ath12k_dp_hw (which is a datapath component of ath12k_hw) and protect this list using spinlock "peer_lock". Store peer id based table (array of RCU pointers) of ath12k_dp_peer in ath12k_dp_hw. Use this peer id table to refer in the per packet Tx and Rx paths as it provides faster access to ath12k_dp_peer in comparison to linked list iterative search using peer id or mac address. Add support to handle deletion of ath12k_dp_peer in case of core reset. This patch is adding and deleting ath12k_dp_peer created for MLO STA to the above mentioned RCU pointer table. Addition and deletion of ath12k_dp_peer for non-MLO STA to RCU pointer table is handled in the subsequent following patch. Structure ath12k_ml_peer is created and deleted for MLO peers at the time of connect and disconnect and there is no other use case of it. With the above design in place for ath12k_dp_peer, ath12k_ml_peer becomes redundant. Hence, remove the structure ath12k_ml_peer and the list "ml_peers" present in ath12k_hw maintaining linked list of ath12k_ml_peer.
