40 * DOC: Introduction
41 *
42 * iwlmld is an operation mode (a.k.a. op_mode) for Intel wireless devices.
43 * It is used for devices that ship after 2024 which typically support
44 * the WiFi-7 features. MLD stands for multi-link device. Note that there are
45 * devices that do not support WiFi-7 or even WiFi 6E and yet use iwlmld, but
46 * the firmware APIs used in this driver are WiFi-7 compatible.
47 *
48 * In the architecture of iwlwifi, an op_mode is a layer that translates
49 * mac80211's APIs into commands for the firmware and, of course, notifications
50 * from the firmware to mac80211's APIs. An op_mode must implement the
51 * interface defined in iwl-op-mode.h to interact with the transport layer
52 * which allows to send and receive data to the device, start the hardware,
53 * etc...
54 */
55
56 /**
57 * DOC: Locking policy
58 *
59 * iwlmld has a very simple locking policy: it doesn't have any mutexes. It
60 * relies on cfg80211's wiphy->mtx and takes the lock when needed. All the
61 * control flows originating from mac80211 already acquired the lock, so that
62 * part is trivial, but also notifications that are received from the firmware
63 * and handled asynchronously are handled only after having taken the lock.
64 * This is described in notif.c.
65 * There are spin_locks needed to synchronize with the data path, around the
66 * allocation of the queues, for example.
67 */
68
69 /**
70 * DOC: Debugfs
71 *
72 * iwlmld adds its share of debugfs hooks and its handlers are synchronized
73 * with the wiphy_lock using wiphy_locked_debugfs. This avoids races against
74 * resources deletion while the debugfs hook is being used.
75 */
76
77 /**
78 * DOC: Main resources
79 *
80 * iwlmld is designed with the life cycle of the resource in mind. The
81 * resources are:
82 *
83 * - struct iwl_mld (matches mac80211's struct ieee80211_hw)
84 *
85 * - struct iwl_mld_vif (matches macu80211's struct ieee80211_vif)
86 * iwl_mld_vif contains an array of pointers to struct iwl_mld_link
87 * which describe the links for this vif.
88 *
89 * - struct iwl_mld_sta (matches mac80211's struct ieee80211_sta)
90 * iwl_mld_sta contains an array of points to struct iwl_mld_link_sta
91 * which describes the link stations for this station
92 *
93 * Each object has properties that can survive a firmware reset or not.
94 * Asynchronous firmware notifications can declare themselves as dependent on a
95 * certain instance of those resources and that means that the notifications
96 * will be cancelled once the instance is destroyed.

109 * ieee80211_txq.

126 * @fw_id_to_link_sta: maps a fw id of a sta to the corresponding

128 * preserve the fw sta ids during a restart (for SN/PN restoring).
129 * FW ids of internal stations will be mapped to ERR_PTR, and will be
130 * re-allocated during a restart, so make sure to free it in restart
