2d64da9ed5 wifi: ath12k: set flag for mgmt no-ack frames in Tx completion
IEEE80211_TX_STAT_NOACK_TRANSMITTED flag signifies that frame was
successfully transmitted without any errors when no-ack is requested.

In WMI Tx management completion path, driver is not setting
IEEE80211_TX_STAT_NOACK_TRANSMITTED flag for the frames with
IEEE80211_TX_CTL_NO_ACK. Without this flag, the management frame
statistics will not track such frames.

Add IEEE80211_TX_STAT_NOACK_TRANSMITTED flag as part of the flags in
skb transmit information when WMI is processing Tx completion for
management frames.

9035756c18 wifi: ath12k: Include MLO memory in firmware coredump collection
The current firmware coredump collection in ath12k does not include
the MLO_GLOBAL_MEM_REGION_TYPE memory. This memory region is essential
for debugging issues related to Multi-Link Operation (MLO).

Hence, add support to include MLO_GLOBAL_MEM_REGION_TYPE memory in
firmware coredump collection.

40562e84e2 wifi: ath12k: handle radar detection with MLO
ieee80211_radar_detected() expects the driver to pass a channel context
configuration during MLO. This is used to identify exactly which link
detected the radar.

Add support to pass this to mac80211. Since the link arvif is not known in
the WMI event, introduce a helper iterator API,
ath12k_mac_get_any_chanctx_conf_iter(), to get the channel context
configuration.

11b86e2ce9 wifi: ath12k: fix CAC running state during virtual interface start
Currently, the DFS CAC time and the usable state of the primary channel in
the channel definition are used to set the CAC_RUNNING flag for the ath12k
radio structure. However, this approach is flawed because there are channel
definitions where the primary channel is not a DFS channel, but the
secondary channel is. For example, in 5 GHz band, channel 36 with 160 MHz
bandwidth. In such cases, the flag is not set correctly and hence places
where this flag is tested will not operate as expected. For example, Rx
packets will not be dropped.

To fix this issue, use the cfg80211_chandef_dfs_usable() function from
cfg80211, which returns true if at least one channel is in a usable state.
This will ensure the CAC_RUNNING flag is set properly.

Additionally, update the CAC running debug log message to include the CAC
time in milliseconds and also print the center frequency segment 1.

8534c42397 wifi: ath12k: Avoid explicit type cast in monitor status parse handler
Currently, monitor status parse procedure handles all the supported TLV
tags. Each TLV tag has its own data structure for parsing. Now, this
handler is passed the tlv_data as a u8 pointer, so explicit type cast
conversion happens for every TLV tag parsing. Therefore, avoid the
explicit type conversion by changing the tlv_data type from a u8 pointer
to a const void pointer.

bf2da5c4f5 wifi: ath12k: Decrease ath12k_mac_station_assoc() stack usage

ath12k_mac_op_sta_state() itself does not consume much stack, but it
calls ath12k_mac_handle_link_sta_state() which in turn calls
ath12k_mac_station_add(). Since those are both static functions with
only one caller, it is suspected that these both get inlined, and
their stack usage is reported for ath12k_mac_op_sta_state().

02213c21fb wifi: ath12k: assign unique hardware link IDs during QMI host cap
Currently, in the QMI host capability, the device index, the number of local
links, and the corresponding hardware link IDs are sent. The hardware link ID
assignment is based on the local variable `hw_link_id`, which starts from 0 and
ranges up to `num_local_links` in the device.  Starting from 0 is not ideal
because it can result in the same link ID being assigned to different devices
in certain scenarios (e.g., split MAC).  Additionally, for multi link
operations the firmware expects the hardware link IDs in the same order as the
Wireless Serial Interface (WSI) connection.

Hence, for MLO to function seamlessly, the hardware link IDs across devices
need to be unique and should follow the order of the WSI connection. To address
this, a previous change read the WSI index from the Device Tree (DT) and stored
it. Use this WSI index to determine the starting hardware link IDs for each
device, ensuring uniqueness and correct order across all devices.

While at it, add debug prints to clearly show the MLO capability advertisement
sent during QMI host capability exchange.

77478788c9 wifi: ath12k: add no-op without debug print in WMI Rx event
Currently, certain WMI events are frequently received by the host. Since
the host lacks the logic to process these events, the console is flooded
with ‘Unknown eventid:’ debug messages.

To address this, handle these events gracefully without printing debug
messages. There is already a block of event IDs that are ignored with a debug
print. However, this new type of event occurs more frequently, so no debug
print is necessary, and handling it should be a no-op.

While at it, re-arrange the code so that all Unknown event IDs are towards
the end of the switch block.

When operating as an ML station, mac80211 initially activates only one link in
the driver until the peer is authorized. Once the state changes to authorized,
the driver should call mac80211 API to activate all other partner links.

Before doing so, mac80211 checks if the driver supports activating links via
the can_activate_links mac80211_ops. Therefore, add support for this
mac80211_ops and call the API to activate the links once the state changes to
authorized.

3863f014ad wifi: ath12k: symmetrize scan vdev creation and deletion during HW scan
Currently, the hardware scan is initiated in the driver on scan link (15).
After mapping to the appropriate radio based on the scan frequency, the vdev is
created and the scan begins. However, the vdev is only deleted when channel
assignment is about to occur after the scan. Additionally, it is also deleted
if a new scan is requested on the same interface but the underlying radio
differs in the new request.

This imbalance leads to various hardware scan issues, especially when a non-MLO
and MLO combination exists. In such cases, the latter tries to skip the scan
and proceed with channel assignment while the former is still scanning, causing
a firmware assert.

To address this issue, symmetrize the scan vdev creation and deletion during
hardware scan operations. This means creating a vdev when the scan starts and
deleting it once the scan is completed or aborted.

While at this, add a few debug prints in scan handling and a few empty lines
for better code read.

The prerequisite for MLO support in cfg80211/mac80211 requires that all the
links participating in MLO belong to the same wiphy/struct ieee80211_hw. The
driver needs to group multiple discrete hardware components, each acting as a
link in MLO, under one wiphy. Consequently, the driver advertises
multi-hardware device interface combination capabilities specific to the radio,
including supported frequencies. The global interface combination represent the
combined interface capabilities.

08a4c51c6e wifi: ath12k: send partner device details in QMI MLO capability
Currently, QMI MLO host capability is sent with the details of local links and
hw_link id only for particular device. But in the case of multi device group
abstraction, it has to include the details of hw_link_id, num_local_links of
every partner device that is involved in the group during QMI MLO capability
exchange. Add changes to send partner device details to the firmware in QMI MLO
capability exchange.

908c10c860 wifi: ath12k: parse multiple device information from Device Tree
Currently, a single device is part of the device group abstraction. However,
for multi-link operations, multiple devices need to be combined. This
multi-device grouping is done via WSI (WLAN Serial Interface), which is
described in the Device Tree. Information about different WSI groups and the
number of devices involved in each group can be parsed from the Device Tree.

Add changes to parse the Device Tree and determine WSI information, such as the
different WSI groups and the number of devices per WSI group. Assign WSI index
zero to the WSI controller device (to synchronize the clock among the devices
within the WSI group), and increment the WSI index of each device in the order
of the WSI connection.

f86e09fd39 dt-bindings: net: wireless: Describe ath12k PCI module with WSI
The QCN9274 WiFi device supports WSI (WLAN Serial Interface). WSI is used
to exchange specific control information across radios using a doorbell
mechanism. This WSI connection is essential for exchanging control
information among these devices. The WSI interface in the QCN9274 includes
TX and RX ports, which are used to connect multiple WSI-supported devices
together, forming a WSI group.

Describe QCN9274 PCI wifi device with WSI interface.

5a10971c76 wifi: ath12k: fix read pointer after free in ath12k_mac_assign_vif_to_vdev()
In ath12k_mac_assign_vif_to_vdev(), if arvif is created on a different
radio, it gets deleted from that radio through a call to
ath12k_mac_unassign_link_vif(). This action frees the arvif pointer.
Subsequently, there is a check involving arvif, which will result in a
read-after-free scenario.

Fix this by moving this check after arvif is again assigned via call to
ath12k_mac_assign_link_vif().

02f41c8aa6 wifi: ath12k: fix leaking michael_mic for non-primary links
In ath12k_dp_rx_peer_frag_setup(), commit ea41925538 ("wifi: ath12k: add primary
link for data path operations") checks whether a link is the primary link, and
returns directly if it isn't. In ML scenario where we have non-primary links created,
this results in leaking the michael_mic info since it is allocated by default but
could never be freed for a non-primary link.

Note that we can not move the might-sleep allocation after primary link check since
there we are in atomic context (due to spin lock). So keep the default allocation,
and then free it before return to fix this issue.

ath.git patches for v6.14

This development cycle featured multiple patchsets to ath12k to
support the new 802.11be MLO feature, although the feature is still
incomplete. Also in ath12k, there were other feature patches.  In
ath11k, support was added for QCA6698AQ. And there was the usual set
of bug fixes and cleanups across most drivers, notable being the
addition of "noinline_for_stack" to some functions to avoid "stack
frame size" warnings when compiling with clang.
