Fine Timing Measurement(FTM) support is used to measure round trip
time between two nodes.
Enable FTM responder feature using hw_params on supported device.
Since FTM functionality is offloaded to firmware, adding the
interface allows user space to enable or disable FTM responder.
Also add support for advertising the same in extended capabilities.
QCA6390, WCN6855 and WCN6750 do not support this feature.

ath11k fails to load if there are multiple ath11k PCI devices with same name:
ath11k_pci 0000:01:00.0: Hardware name qcn9074 hw1.0
debugfs: Directory 'ath11k' with parent '/' already present!
ath11k_pci 0000:01:00.0: failed to create ath11k debugfs
ath11k_pci 0000:01:00.0: failed to create soc core: -17
ath11k_pci 0000:01:00.0: failed to init core: -17
ath11k_pci: probe of 0000:01:00.0 failed with error -17
Fix this by creating a directory for each ath11k device using schema
<bus>-<devname>, for example "pci-0000:06:00.0". This directory created under
the top-level ath11k directory, for example /sys/kernel/debug/ath11k.
The reference to the toplevel ath11k directory is not stored anymore within ath11k, instead
it's retrieved using debugfs_lookup(). If the directory does not exist it will
be created. After the last directory from the ath11k directory is removed, for
example when doing rmmod ath11k, the empty ath11k directory is left in place,
it's a minor cosmetic issue anyway.
Here's an example hierarchy with one WCN6855:
ath11k
`-- pci-0000:06:00.0
|-- mac0
| |-- dfs_block_radar_events
| |-- dfs_simulate_radar

|-- simulate_fw_crash
`-- soc_dp_stats
I didn't have a test setup where I could connect multiple ath11k devices to the
same the host, so I have only tested this with one device.

Currently, ath11k sends peer assoc command for each peer to
firmware when bandwidth changes. Peer assoc command is a
bulky command and if many clients are connected, this could
lead to firmware buffer getting overflowed leading to a firmware
assert.
However, during bandwidth change, only phymode and bandwidth
also can be updated by WMI set peer param command. This makes
the overall command light when compared to peer assoc and for
multi-client cases, firmware buffer overflow also does not
occur.
Remove sending peer assoc command during sta bandwidth change
and instead add sending WMI set peer param command for phymode
and bandwidth.

Currently, recovery flag is set immediately upon firmware
exit but tx queues are stopped once firmware arrives back
and is ready which is during ath11k_core_restart. Once
ieee80211 hw restart is completed, tx queues are resumed.
If during the time delta between firmware exit and firmware
ready, mac80211 send packets, currently ath11k will drop it
since recovery flag will be set. But warning prints will
come -
"ath11k c000000.wifi: failed to transmit frame -108"
If more tx packets are there, this could lead to flooding
of above print.
However, actually tx queues should be stopped immediately
when firmware leaves. This will prevent packets to get
dropped when firmware is recovering.
Add fix to stop tx queues immediately after firmware exit.

Add support to get the following power save information through debugfs interface,
* Current ps state of the peer
* Time duration since the peer is in power save
* Total duration of the peer spent in power save
Above information is helpful in debugging the issues with power save clients.
This patch also add trace log support for PS timekeeper to track the PS state
change of the peers alongs with the peer MAC address and timestamp.
Use the below commands to get the above power save information,
To know the time_since_station_in_power_save:
cat /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/
XX:XX:XX:XX:XX:XX/current_ps_duration
To know power_save_duration:
cat /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/
XX:XX:XX:XX:XX:XX/total_ps_duration
To reset the power_save_duration of all stations connected to AP:
echo 1 > /sys/kernel/debug/ieee80211/phyX/ath11k/reset_ps_duration
To enable/disable the ps_timekeeper:
echo Y > /sys/kernel/debug/ieee80211/phyX/ath11k/ps_timekeeper_enable
Y = 1 to enable and Y = 0 to disable.
To record PS timekeeer logs after enabling ps_timekeeper:

Currently ar->ht_cap_info is not set anywhere in the code, this could
result in LDPC config computed wrongly in the set_bitrate_mask() hook
and eventually sending wrong config to the target. Fix this by checking
the LDPC support from the band HT capabilities of the radio instead.
Furthermore, it looks like firmwares running on the ath11k hardware
do not set WMI_HT_CAP_LDPC for advertising the TX LDPC capability,
WMI_HT_CAP_TX_LDPC is set instead and this should be checked for
getting hardware's TX LDPC support. This is true for QCA6390, WCN6855
& WCN6750 hardware.
Also, remove unused variables ht_cap_info & vht_cap_info from
struct ath11k{}.

WCN6750 is non-DBS 2x2 11AX chipset. Unlike QCA6390 which is a
DBS (dual band simultaneous) solution (2 LMACs), WCN6750 has a
single LMAC supporting 2G, 5G and 6G bands but will operate only
on one band at any given point.
WCN6750 is a PCIe based solution, but it is attached to the WPSS
(Wireless Processor SubSystem) Q6 processor, hence it is enumerated
by the Q6 processor. It is registered to the APSS processor
(Application Processor SubSystem) as a platform device(AHB) and
remoteproc APIs are used to boot up or shutdown the device like
other AHB devices.
Also, Device information like BAR and it's size is not known to the
APSS processor as the chip is enumerated by WPSS Q6. These details
are fetched over QMI.
STA and AP modes are supported. Verified basic connectivity and ping
in both the modes.
An important point to note is that though WCN6750 is a PCIe device,
it cannot be attached to any other platform except on Qualcomm
Snapdragon SoCs due to the aforementioned reasons.

Though it is a PCIe device, since it is not attached to APSS processor
(Application Processor SubSystem), APSS will be unaware of such a decice
and hence it is registered to the APSS processor as a platform device(AHB).
Because of this hybrid nature, it is called as a hybrid bus device.

hybrid nature of the device.

In ath11k, bus_params were added with an intention to hold
parameters related to bus (AHB/PCI), but this is not true
as some bus parameters being different between chipsets of
the same bus.
With the addition of WCN6750 to ath11k, bus parameters are
going to be entirely different among AHB devices. Therefore,
it is wise to move bus_params to hw_params and get rid of
bus_params entirely.
Also, mhi_support parameter is not used anywhere in the driver,
remove it from bus_params.

from PCI common code. Since, PCI common code will be used
by hybrid bus devices, this code should be independent
from ATH11K PCI references and Linux core PCI references
like struct pci_dev.
Since this change introduces function callbacks for bus wakeup
and bus release operations, wakeup_mhi HW param is no longer
needed and hence it is removed completely. Alternatively, bus
wakeup/release ops for QCA9074 are initialized to NULL as
QCA9704 does not need bus wakeup/release for register accesses.

Currently ath11k will wait 11d scan complete while add interface in
ath11k_mac_op_add_interface(), when system resume without enable
wowlan, ath11k_mac_op_add_interface() is called for each resume, thus
it increase the resume time of system. And ath11k_mac_op_hw_scan()
after ath11k_mac_op_add_interface() also needs some time cost because
the previous 11d scan need more than 5 seconds when 6 GHz is enabled,
then the scan started event will indicated to ath11k after the 11d
scan completed.
While 11d scan/hw scan is running in firmware, if ath11k update channel
list to firmware by WMI_SCAN_CHAN_LIST_CMDID, then firmware will cancel
the current scan which is running, it lead the scan failed. The patch
commit 9dcf6808b253 ("ath11k: add 11d scan offload support") used
finish_11d_scan/finish_11d_ch_list/pending_11d to synchronize the 11d
scan/hw scan/channel list between ath11k/firmware/mac80211 and to avoid
the scan fail.
Add wait operation before ath11k update channel list, function
ath11k_reg_update_chan_list() will wait until the current 11d scan/hw
scan completed. And remove the wait operation of start 11d scan and
waiting channel list complete in hw scan. After these changes, resume
time cost reduce about 5 seconds and also hw scan time cost reduced
obviously, and scan failed not seen.
The 11d scan is sent to firmware only one time for each interface added
in mac.c, and it is moved after the 1st hw scan because 11d scan will
cost some time and thus leads the AP scan result update to UI delay.
Currently priority of ath11k's hw scan is WMI_SCAN_PRIORITY_LOW, and
priority of 11d scan in firmware is WMI_SCAN_PRIORITY_MEDIUM, then the
11d scan which sent after hw scan will cancel the hw scan in firmware,
so change the priority to WMI_SCAN_PRIORITY_MEDIUM for the hw scan which
is in front of the 11d scan, thus it will not happen scan cancel in
firmware.

When more clients (128) are connected, the UL data traffic
KPI measurement is low compared to single client. This issue
is due to more CPU cycles spent on the peer lookup operation
with more clients. So reduce the peer lookup operation by
modifying the linear based lookup operation into the rhash
based lookup operation. This improve the peak throughput
measurement. Since this is a software algorithm change, it is
applicable for all the platforms.

ieee80211_reconfig() of mac80211 is the main function for recovery of
each ieee80211_hw and ath11k, and ath11k_core_reconfigure_on_crash()
is the main function for recovery of ath11k_base, it has more than
one ieee80211_hw and ath11k for each ath11k_base, so it need to add
synchronization between them, otherwise it has many issue.
For example, when ath11k_core_reconfigure_on_crash() is not complete,
mac80211 send a hw scan request to ath11k, it leads firmware crash,
because firmware has not been initialized at that moment, firmware
is only finished downloaded and loaded, it can not receive scan
command.

Currently ath11k has device recovery logic, it is introduced by this
patch "ath11k: Add support for subsystem recovery" which is upstream
by https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=ath11k-bringup&id=3a7b4838b6f6f234239f263ef3dc02e612a083ad.
The patch is for AHB devices such as IPQ8074, it has remote proc module
which is used to download the firmware and boots the processor which
firmware is running on. If firmware crashed, remote proc module will
detect it and download and boot firmware again. Below command will
trigger a firmware crash, and then user can test feature of device
recovery.
Test command:
echo assert > /sys/kernel/debug/ath11k/qca6390\ hw2.0/simulate_fw_crash
echo assert > /sys/kernel/debug/ath11k/wcn6855\ hw2.0/simulate_fw_crash
Unfortunately, QCA6390 is PCIe bus, it does not have the remote proc
module, it use mhi module to communicate between firmware and ath11k.
So ath11k does not support device recovery for QCA6390 currently.
This patch is to add the extra logic which is different for QCA6390.
When firmware crashed, MHI_CB_EE_RDDM event will be indicate by
firmware and then ath11k_mhi_op_status_cb which is the callback of
mhi_controller will receive the MHI_CB_EE_RDDM event, then ath11k
will start to do recovery process, ath11k_core_reset() calls
ath11k_hif_power_down()/ath11k_hif_power_up(), then the mhi/ath11k
will start to download and boot firmware. There are some logic to
avoid deadloop recovery and two simultaneous recovery operations.
And because it has muti-radios for the soc, so it add some logic
in ath11k_mac_op_reconfig_complete() to make sure all radios has
reconfig complete and then complete the device recovery.
Also it add workqueue_aux, because ab->workqueue is used when receive
ATH11K_QMI_EVENT_FW_READY in recovery process(queue_work(ab->workqueue,
&ab->restart_work)), and ath11k_core_reset will wait for max
ATH11K_RESET_TIMEOUT_HZ for the previous restart_work finished, if
ath11k_core_reset also queued in ab->workqueue, then it will delay
restart_work of previous recovery and lead previous recovery fail.
ath11k recovery success for QCA6390/WCN6855 after apply this patch.

Add debugfs interface "fw_dbglog_config" to configure firmware log level.
Configuration is done via WMI command WMI_DBGLOG_CFG_CMDID.
Command to configure,
echo "<dbglog_param> <values>" >
/sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
where dbglog_param can be,
1) WMI_DEBUG_LOG_PARAM_LOG_LEVEL - configure log level for a given module
here, <values> = <0xaaaa00bb>, 'aaaa' - module id and 'bb' - loglevel
2) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE - enable debug log for a given vdev
here, <values> = vdev_id
3) WMI_DEBUG_LOG_PARAM_VDEV_DISABLE - disable debug log for a given vdev
except ERROR logs
here, <values> = vdev_id
4) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE_BITMAP - set vdev enable bitmap
here, <values> = vdev_enable_bitmap
5) WMI_DEBUG_LOG_PARAM_MOD_ENABLE_BITMAP - set a given log level to all the
modules specified in the module bitmap. Command to configure for this log param,
$ echo "5 <values> <module_id_index> <is_end>" >
/sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
here,
<values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and
'bb' - loglevel
<module_id_index> = index of module bitmap. Max module id is 512.
So, module_id_index is 0-15.
<is_end> = to indicate if more configuration to follow.
6) WMI_DEBUG_LOG_PARAM_WOW_MOD_ENABLE_BITMAP - Wow mode specific logging enable.
Command to configure for this log param,
$ echo "6 <values> <module_id_index> <is_end>" >
/sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
here,
<values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and
'bb' - loglevel
<module_id_index> = index of module bitmap. Max module id is 512.
So, module_id_index is 0-15.
<is_end> = to indicate if more configuration to follow.
Sample command usage,
To enable module WLAN_MODULE_WMI and log level ATH11K_FW_DBGLOG_VERBOSE,
echo "1 0x10001" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
To enable module bit map from 32 to 63 and log level ATH11K_FW_DBGLOG_VERBOSE,

There is an issue that WCN6855 tries to connect to an AP using
a hardware rate of 1Mb/s , even though the AP has announced
expected rates as [24, 36, 48, 54] in Probe Response frame.
The reason is that WCN6855 firmware clears hardware rate info
of management frames when vdev starts and uses 1Mb/s as default.
To solve it, reconfigure the rate after vdev is started.

The regdomain is self-managed type for ath11k, the regdomain info is
reported from firmware, it is not from wireless regdb. Firmware fetch
the regdomain info from board data file before. Currently most of the
regdomain info has moved to another file regdb.bin from board data
file for some chips such as QCA6390 and WCN6855, so the regdomain info
left in board data file is not enough to support the feature which need
more regdomain info.
After download regdb.bin, firmware will fetch the regdomain info from
regdb.bin instead of board data file and report to ath11k. If it does
not have the file regdb.bin, it also can initialize wlan success and
firmware then fetch regdomain info from board data file.
Add download the regdb.bin before download board data for some specific
chip which support supports_regdb in hardware parameters.

When hardware rfkill is enabled in the firmware it will report the
capability via using WMI_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY
event to the host. ath11k will check the capability, and if it is enabled then
ath11k will set the GPIO information to firmware using WMI_PDEV_SET_PARAM. When
the firmware detects hardware rfkill is enabled by the user, it will report it
via WMI_RFKILL_STATE_CHANGE_EVENTID. Once ath11k receives the event it will
send wmi command WMI_PDEV_SET_PARAM to the firmware and also notifies cfg80211.
This only enable rfkill feature for QCA6390, rfkill_pin is all initialized to 0

In ath11k, tx of management packet is doing in a work queue. Sometimes
the workqueue does not finish tx immediately, then it lead after the next
step of vdev delete finished, it start to send the management packet to
firmware and lead firmware crash.
ieee80211_set_disassoc() have logic of ieee80211_flush_queues() after
it send_deauth_disassoc() to ath11k, its purpose is make sure the

Ath11k fails to probe WCN6855 hw2.1 chip:
[ 6.983821] ath11k_pci 0000:06:00.0: enabling device (0000 -> 0002)
[ 6.983841] ath11k_pci 0000:06:00.0: Unsupported WCN6855 SOC hardware version: 18 17
This is caused by the wrong bit mask setting of hardware major version:
for QCA6390/QCN6855, it should be BIT8-11, not BIT8-16, so change the
definition to GENMASK(11, 8).
Also, add a separate entry for WCN6855 hw2.1 in ath11k_hw_params.
Please note that currently WCN6855 hw2.1 shares the same firmwares
as hw2.0, so users of this chip need to create a symlink as below:
ln -s hw2.0 hw2.1

This reverts commit 46e46db313a2bf3c48cac4eb8bdb613b762f301b. Mark reported
that it breaks QCA6390 hw2.0 on Dell XPS 13 9310:
[ 5.537034] ath11k_pci 0000:72:00.0: chip_id 0x0 chip_family 0xb board_id 0xff soc_id 0xffffffff
[ 5.537038] ath11k_pci 0000:72:00.0: fw_version 0x101c06cc fw_build_timestamp 2020-06-24 19:50 fw_build_id
[ 5.537236] ath11k_pci 0000:72:00.0: failed to fetch board data for bus=pci,qmi-chip-id=0,qmi-board-id=255,variant=DE_1901 from ath11k/QCA6390/hw2.0/board-2.bin
[ 5.537255] ath11k_pci 0000:72:00.0: failed to fetch board-2.bin or board.bin from QCA6390/hw2.0
[ 5.537257] ath11k_pci 0000:72:00.0: qmi failed to fetch board file: -2
[ 5.537258] ath11k_pci 0000:72:00.0: failed to load board data file: -2
So we need to back to the drawing board and implement it so that backwards
compatiblity is not broken.

This is to read variant from SMBIOS such as read from DT, the variant
string will be used to one part of string which used to search board
data from board-2.bin.

The pdev id is set to 0 for single pdev configured hardware, the real
pdev id is not 0 in firmware, for example, its pdev id is 1 for 5G/6G
phy and 2 for 2G band phy. For HTT_H2T_MSG_TYPE_EXT_STATS_CFG message,
firmware parse the pdev_mask to its pdev id, ath11k set it to 0 for
single pdev, it is not correct, need set it with the real pdev id of
firmware.
Save the real pdev id report by firmware and set it correctly.

This change adds two flags to indicate whether IRQ handler for CE
and DP can be called. This is because in one MSI vector case,
interrupt is not disabled in hif_stop and hif_irq_disable. Otherwise,
MHI interrupt is disabled too.
