Sowmiya Sree Elavalagan f5c90ff80b wifi: ath12k: Add Support to Calculate and Display TPC Values
Transmit Power Control(TPC) stats should display per chain TPC value per
radio. Add debugfs support to read and display TPC stats type and TPC
stats. Take power values for each preamble type, rate and NSS combination
from a particular index from each power arrays based on number of chains,
NSS, modes, MCS and tx beamforming enabled/disabled parameters. Minimum
of the values taken from reg power table, rates and Conformance Test
Limit(CTL) array table should give the TPC which is in 0.25 dBm steps.

Sowmiya Sree Elavalagan f0c3bb78e4 wifi: ath12k: Add Support to Parse TPC Event from Firmware
Host receives four Transmit Power Control(TPC) events from firmware on
sending TPC request. Fixed param TLV is present as part of all event to
indicate the event count and end of event. TPC config parameters along
with regulatory power array comes as first event. Rates array comes as
second and third event as it cannot be packed in single event.
Conformance Test Limit (CTL) power array comes as the fourth event.
Firmware packs different sets of array params which includes array
length and type inside master TLV as different subtlvs. And the actual
content of array is packed one after the other inside a separate TLV as
single buffer.

Parse various events and save it in local structures. Create tpc_stats
file using debugfs to store these local structures. Create function to
handle TPC stats read to relay the information to the user.

Command usage:

Aditya Kumar Singh 4094445969 wifi: ath12k: update beacon template function to use arvif structure
The current code has ath12k_wmi_bcn_tmpl() accepting separate ar and
vdev_id parameters. However, ath12k_link_vif structure can be used to
derive both of these.

Hence, simplify the function signature.

Later change needs arvif pointer access within the function hence it is
better if arvif is directly passed now.

Lingbo Kong 79e7b04b53 wifi: ath12k: report station mode signal strength
Currently, the signal strength of "iw dev xxx station dump" always show an
invalid value.

This is because signal strength is only set in ath12k_mgmt_rx_event()
function, and not set for received data packet. So, change to get signal
from firmware and report to mac80211.

After that, "iw dev xxx station dump" show the correct signal strength.
Such as:

Station 00:03:7f:12:03:03 (on wlo1)
        inactive time:  36 ms
        rx bytes:       61571
        rx packets:     336
        tx bytes:       28204
        tx packets:     205
        tx retries:     49
        tx failed:      0
        beacon loss:    0
        beacon rx:      83
        rx drop misc:   66
        signal:         -24 dBm
        beacon signal avg:      -22 dBm

For WCN7850, the firmware supports db2dbm, so not need to add noise floor.
For QCN9274, the firmware not support db2dbm, so need to add noise floor.

This patch affects the station mode of WCN7850 and QCN9274.

Aditya Kumar Singh 64a1ba4072 wifi: ath12k: fix handling of 6 GHz rules
In the US country code, to avoid including 6 GHz rules in the 5 GHz rules
list, the number of 5 GHz rules is set to a default constant value of 4
(REG_US_5G_NUM_REG_RULES). However, if there are more than 4 valid 5 GHz
rules, the current logic will bypass the legitimate 6 GHz rules.

For example, if there are 5 valid 5 GHz rules and 1 valid 6 GHz rule, the
current logic will only consider 4 of the 5 GHz rules, treating the last
valid rule as a 6 GHz rule. Consequently, the actual 6 GHz rule is never
processed, leading to the eventual disabling of 6 GHz channels.

To fix this issue, instead of hardcoding the value to 4, use a helper
function to determine the number of 6 GHz rules present in the 5 GHz rules
list and ignore only those rules.

firmware needs to be restarted in FTM mode using module parameter ftm_mode.
The pre-request is all the radios should be down before starting the test.

All ath12k test mode interface related commands specified in enum
ath_tm_cmd.

When start command ATH_TM_CMD_TESTMODE_START is received, ar state
is set to test Mode and FTM daemon sends test mode command to wifi
driver via cfg80211. Wifi driver sends these command to firmware as
wmi events. If it is segmented commands it will be broken down into
multiple segments and encoded with TLV header else it is sent to
firmware as it is.

Firmware response via UTF events, wifi driver creates skb and send
to cfg80211, cfg80211 sends firmware response to FTM daemon via
netlink message.

Command to boot in ftm mode
insmod ath12k ftm_mode=1

Aditya Kumar Singh 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.

Sriram R 3dd2c68f20 wifi: ath12k: prepare vif data structure for MLO handling
To prepare the driver for MLO support, split the driver vif data structure to
scale for multiple links. This requires changing the use of arvif to per link
and not per hw which can now comprise of multiple links. Also since most
configurations from mac80211 are done per link, do refactoring of the driver
functions to apply these configurations at link level.

Split ath12k_vif which is the driver private of ieee80211_vif to store link
specific information as ath12k_link_vif. For default use cases the ath12k vif
will have a preallocated link vif called deflink which will be used by non ML
and the first link vif of ML vif.

With MLO support to be added, remaining link vifs will be allocated during
channel assignment where vdev create/start happens. These link vifs will be
freed during interface down.

To refactor existing ath12k_vif to make use of link vifs, following
changes are made:

 1. ath12k_vif now called by variable name ahvif storing multiple
    arvifs (struct ah12k_link_vif) and also has a back pointer to ieee80211_vif.

 2. In this patch set, only deflink is used to be on par with the
    existing code. When MLO support is added the link id will be used to fetch
    the arvif.

 3. For mac80211 ops which doesn't use specific link_id, the config or info
    is common for the vif, hence apply the config to all link vifs.
    The links_map in the ahvif, will be used to identify all the link vifs that
    are setup.

 4. Change ath12k_vif_to_arvif() as ath12k_vif_to_ahvif() to fetch the
    hw level vif. The link vif can be fetched from ahvif->link[], or the
    deflink can be accessed via ahvif->deflink. API to access link
    vif (arvif) by passing link_id can be introduced with MLO Support.

 5. The ieee80211_vif can be accessed from ahvif using ath12k_ahvif_to_vif().

The locking continues to use wiphy_lock() for protecting access to most data in
struct ath12k&co, there are no changes in that regard. Though struct
ath12k_vif::link[] is protected with RCU.

Currently, the firmware returns incorrect pdev_id information in

To prevent this issue, when requesting BSS channel information
through WMI_PDEV_BSS_CHAN_INFO_REQUEST_CMDID, firmware expects
pdev_id as one of the arguments in this WMI command.

Add pdev_id to the struct wmi_pdev_bss_chan_info_req_cmd and fill it
during ath12k_wmi_pdev_bss_chan_info_request(). This resolves the
issue of sending the correct pdev_id in WMI_PDEV_BSS_CHAN_INFO_EVENTID.

With WoWLAN enabled and after sleeping for a rather long time,
we are seeing that with some APs, it is not able to wake up
the STA though the correct wake up pattern has been configured.
This is because the host doesn't send keepalive command to
firmware, thus firmware will not send any packet to the AP and
after a specific time the AP kicks out the STA.

So enable keepalive before going to suspend and disable it after
resume back.

scans periodically and wakes up host if a specific
SSID is found.

Note that firmware crashes if we enable it for both
P2P vdev and station vdev simultaneously because
firmware can only support one vdev at a time. Since
there is rare scenario for a P2P vdev to do net-detect,
skip it for P2P vdevs.

The current value of the MAX_RADIOS definition is 3. This is incorrect
because no device supports more than 2 radios.

An incorrect MAX_RADIOS value can lead to:

 - invalid pdev id validation.
 - Misconceptions for code readers.

Therefore, modify the MAX_RADIOS definition as 2.

Kang Yang b0afabc4d7 wifi: ath12k: add support to handle beacon miss for WCN7850
When AP goes down or too far away without indication to STA, beacon miss
will be detected. Then for WCN7850's firmware, it will use roam event
to send beacon miss to host.

If STA doesn't handle the beacon miss, will keep the fake connection
and unable to roam.

So add support for WCN7850 to trigger disconnection from AP when
receiving this event from firmware.

It has to be noted that beacon miss event notification for QCN9274
to be handled in a separate patch as it uses STA kickout WMI event
to notify beacon miss and the current STA kickout event is processed
as low_ack.

Current driver only update puncturing bitmap to firmware as vdev
parameter. Which can only meet the needs of AP. But STA will also use
it as peer parameter. If only update as vdev parameter, might cause
firmware crash. QCN9274 is the same.

So update bandwidth and puncturing bitmap as peer parameters once they
changed for STA. Then send them to the firmware by WMI event.
