WCN6750 firmware crashes because of num_vdevs changed from 4 to 17
in ath11k_init_wmi_config_qca6390() as the ab->hw_params.num_vdevs
is 17. This is caused by commit f019f4dff2 ("wifi: ath11k: support
2 station interfaces") which assigns ab->hw_params.num_vdevs directly
to config->num_vdevs in ath11k_init_wmi_config_qca6390(), therefore
WCN6750 firmware crashes as it can't support such a big num_vdevs.
Fix it by assign 3 to num_vdevs in hw_params for WCN6750 as 3 is
sufficient too.

Now that all infrastructure is in place and ath11k is fixed to handle all the
corner cases, power down the ath11k firmware during suspend and power it back
up during resume. This fixes the problem when using hibernation with ath11k PCI
devices.
For suspend, two conditions needs to be satisfied:
1. since MHI channel unprepare would be done in late suspend stage,
ath11k needs to get all QMI-dependent things done before that stage.
2. and because unprepare MHI channels requires a working MHI stack,
ath11k is not allowed to call mhi_power_down() until that finishes.
So the original suspend callback is separated into two parts: the first part
handles all QMI-dependent things in suspend callback; while the second part
powers down MHI in suspend_late callback. This is valid because kernel calls
ath11k's suspend callback before all suspend_late callbacks, making the first
condition happy. And because MHI devices are children of ath11k device
(ab->dev), kernel guarantees that ath11k's suspend_late callback is called
after QRTR's suspend_late callback, this satisfies the second condition.
Above analysis also applies to resume process. so the original resume
callback is separated into two parts: the first part powers up MHI stack
in resume_early callback, this guarantees MHI stack is working when
QRTR tries to prepare MHI channels (kernel calls QRTR's resume_early callback
after ath11k's resume_early callback, due to the child-father relationship);
the second part waits for the completion of restart, which won't fail now
since MHI channels are ready for use by QMI.
Another notable change is in power down path, we tell mhi_power_down() to not
to destroy MHI devices, making it possible for QRTR to help unprepare/prepare
MHI channels, and finally get us rid of the probe-defer issue when resume.
Also change related code due to interface changes.

QCA2066 is a PCI based DBS device. It is very similar to WCN6855
overall: they share the same PCI device ID, the same major and
minor version numbers, the same register address, and same HAL
descriptors etc. The most significant difference is that QCA2066
supports 3-antenna configuration while WCN6855 does not. To differentiate
them, subversion numbers are used. Currently four numbers are used
by QCA2066: 0x1019A0E1, 0x1019B0E1, 0x1019C0E1 and 0x1019D0E1.

Firmware IE containers can dynamically provide various information
what firmware supports. Also it can embed more than one image so
updating firmware is easy, user just needs to update one file in
/lib/firmware/.
The firmware API 2 or higher will use the IE container format, the
current API 1 will not use the new format but it still is supported
for some time. Firmware API 2 files are named as firmware-2.bin
(which contains both amss.bin and m3.bin images) and API 1 files are
amss.bin and m3.bin.
Currently ath11k PCI driver provides firmware binary (amss.bin) path to
MHI driver, MHI driver reads firmware from filesystem and boots it. Add
provision to read firmware files from ath11k driver and provide the amss.bin
firmware data and size to MHI using a pointer.
Currently enum ath11k_fw_features is empty, the patches adding features will
add the flags.
With AHB devices there's no amss.bin or m3.bin, so no changes in how AHB
firmware files are used. But AHB devices can use future additions to the meta
data, for example in enum ath11k_fw_features.

Add support to process factory test mode commands (FTM) for calibration.
By default firmware start with NORMAL mode and to process the FTM commands
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.
When start command ATH11K_TM_CMD_TESTMODE_START is received, ar->state
is set to Test Mode. If the FTM command or event length is greater
than 256 bytes, it will be broken down into multiple segments and
encoded with TLV header if it is segmented commands, else it is sent
to firmware as it is.
On receiving UTF event from firmware, if it is segmented event, the driver
will wait until it receives all the segments and notify the complete
data to user application. In case the segmented sequence are missed or
lost from the firmware, driver will skip the already received partial data.
In case of unsegmented UTF event from firmware, driver notifies the
data to the user application as it comes. Applications handles
the data further.
Command to boot in ftm mode:
insmod ath11k ftm_mode=1

Currently after the hardware restart triggered from the driver, the
station interface connection remains intact, since a disconnect trigger
is not sent to userspace. This can lead to a problem in targets where
the wifi mac sequence is added by the firmware.
After the target restart, its wifi mac sequence number gets reset to
zero. Hence AP to which our device is connected will receive frames with
a wifi mac sequence number jump to the past, thereby resulting in the
AP dropping all these frames, until the frame arrives with a wifi mac
sequence number which AP was expecting.
To avoid such frame drops, its better to trigger a station disconnect
upon target hardware restart which can be done with API
ieee80211_reconfig_disconnect exposed to mac80211.
The other targets are not affected by this change, since the hardware
params flag is not set.

So after firmware recovery is successful, when monitor

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.

There are two types of 160 MHz spectral scan support mentioned below
1. Fragmented approach
2. Single event approach
In this fragmented approach, single 160 MHz will be split as two
80 MHz buffer. First fft sample buffer will contain spectral scan
result of primary 80 MHz and the second fft sample buffer will contain
secondary 80 MHz and here cfreq1 and cfreq2 will be mentioned.
In case of 160 MHz on 36th channel will contain cfreq1 as 5210 and
cfreq2 as 5290. Chipsets which support this approach are IPQ8074/IPQ6018.
Replacing freq1 with freq2 in every secondary sepctral scan event to
distinguish between two different 80 MHz spectral event data.
In the 2nd approach each fft sample buffer will contain spectral scan
result for whole 160 MHz by mentioning cfreq1 as 5250 which is center
frequency of whole 160 MHz. Chipset which support this approach is QCN9074.
Host will receive spectral event from target for every 5 fft samples.

Currently, firmware stats, comprising pdev, vdev and beacon stats are
part of debugfs. In firmware pdev stats, firmware reports the final
Tx power used to transmit each packet. If driver wants to know the
final Tx power being used at firmware level, it can leverage from
firmware pdev stats.
Move firmware stats out of debugfs context in order to leverage
the final Tx power reported in it even when debugfs is disabled.

Currently commit 1f682dc9fb ("ath11k: reduce the wait time of 11d scan
and hw scan while add interface") introduced a wait_for_completion_timeout
operation for ar->scan.completed, another one is existed in ath11k_scan_stop(),
then ath11k has two places to wait for the ar->scan.completed and they
run in different thread, thus it is possible to happend that the two
thread both enter wait status. To handle this scenario, ath11k should
change the complete() to complete_all() for the ar->scan.completed. This
also work well when it is only one thread wait for ar->scan.completed.

Currently in the case of WCN6750, only one TCL ring is used for TX,
this is limiting the TX throughput in 160 MHz case, enabling multiple
TCL rings on WCN6750 has shown an improvement of nearly 300 Mbps in
the case of TCP TX, therefore add the support of multi TX ring for
WCN6750.
Currently TCL ring is selected based on CPU ID, this logic cannot be
applied for WCN6750 as there is chance of out of order TX of packets
and to avoid this, choose TCL ring based on flow hash so that packets
of the same flow will end up on same TCL ring. For the same reason,
TCL ring retry logic is also not applicable for WCN6750.
Also the mapping of TCL, WBM & RBM IDs for WCN6750 is different from
existing devices. Create a new TCM/WBM/RBM mapping for WCN6750.
Change does not impact existing ath11k devices.

When the system shuts down, SMMU driver will be stopped and
will not assist in IOVA translations. SMMU driver expects all
of its consumers to shutdown before shutting down itself.
WCN6750 being one of the consumer device should not perform any
DMA operations after the SMMU has shutdown which will otherwise
result in SMMU faults.
SMMU driver will call the shutdown() callback of all its
consumer devices and the consumers shall stop further DMA
activity after the invocation of their respective shutdown()
callbacks.
Register the shutdown() callback to the platform core for WCN6750.

Commit 56c8ccf331 ("ath11k: Add register access logic for WCN6750")
regressed QCN9074. With the above mentioned commit, writes are failing
for some registers on QCN9074 although the device seems to work
normally.
ath11k_pci 0000:03:00.0: failed to set pcie link register0x01e0e0a8: 0xffffffff != 0x00000010
ath11k_pci 0000:03:00.0: failed to set sysclk: -110
PCIe devices in ath11k (QCA6390, WCN6855, QCN9074, WCN6750) use window
concept for register accesses. There are two schemes, dynamic & static
window.
In dynamic window scheme, a single window(region in the BAR) is mapped
either to CE or DP register windows at any give time. QCA6390 & WCN6855
follow this scheme for register accesses.
In static window scheme, CE & DP register windows are statically mapped
to separate regions with in the BAR so that there is no switching of
register windows between CE & DP register accesses. QCN9074 & WCN6750
follow this scheme although the window start offsets are different for
QCN9074 & WCN6750.
QCN9074 uses 3rd & 2nd window for DP & CE register accesses respectively
whereas WCN6750 uses 1st & 2nd window for DP & CE. In QCN9074, along with
2nd & 3rd windows, 1st window is also used for certain configurations
which commit 56c8ccf331 ("ath11k: Add register access logic for WCN6750")
did not account for and hence the regression.
Fix this by going back to the original way of accessing the registers on
QCN9074. Since this diverges from WCN6750 way of accessing registers, it
is required to register window_read32/window_write32() pci_ops for WCN6750.
We can also get rid of dp_window_idx & ce_window_idx members in hw_params,
so remove them.
Also add a new API ath11k_pcic_register_pci_ops() for registering pci_ops
to the ath11k core. This API checks for mandatory pci_ops() and reports
error if those are missing. Also initialize unused pci_ops to NULL.

Ath11k allocates memory when firmware requests memory in QMI.
Coldboot calibration and firmware recovery uses firmware reload.
On firmware reload, firmware sends memory request again. If Ath11k
allocates memory on first firmware boot, reuse the available
memory. Also check if the segment type and size is same
on the next firmware boot. Reuse if segment type/size is
same as previous firmware boot else free the segment and
allocate the segment with size/type.

In case of Passpoint, the WLAN interface may be requested to
remain on a specific channel and then to send some management
frames on that channel. Now chanfreq of wmi_mgmt_send_cmd is set

When doing simulate_fw_crash operation periodically with a short interval
time such as 10 seconds, it is easy happened WMI command timed out for
WMI_SCAN_CHAN_LIST_CMDID in ath11k_reg_update_chan_list().
log:
[42287.610053] ath11k_pci 0000:01:00.0: wmi command 12291 timeout
[42287.610064] ath11k_pci 0000:01:00.0: failed to send WMI_SCAN_CHAN_LIST cmd
[42287.610073] ath11k_pci 0000:01:00.0: failed to perform regd update : -11
Note that this issue does not occur with a longer interval such as 20 seconds.
The reason the issue occurs with a shorter interval is the following steps:
1) Upon initial boot, or after device recovery, the initial hw scan plus
the 11d scan will run, and when 6 GHz support is present, these scans
can take up to 12 seconds to complete, so ath11k_reg_update_chan_list()
is still waiting the completion of ar->completed_11d_scan.
2) If a simulate_fw_crash operation is received during this time, those
scans do not complete, and ath11k_core_pre_reconfigure_recovery()
complete the ar->completed_11d_scan, then ath11k_reg_update_chan_list()
wakeup and start to send WMI_SCAN_CHAN_LIST_CMDID, but firmware is crashed
at this moment, so wmi timed out occur.
To address this issue, reset the 11d state during device recovery so that
WMI_SCAN_CHAN_LIST_CMDID does not timed out for short interval time such
as 10 seconds.

via QMI, instead it uses a fixed 12MB reserved Memory region
in the DDR which is called as MSA region. As a result, QMI

Unlike QCN9074 which uses 3rd window for UMAC and 2nd window
for CE register access, WCN6750 uses 1st window for UMAC

WCN6750 is a PCIe based solution that is attached to and enumerated
by the WPSS (Wireless Processor SubSystem) Q6 processor.
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.
A new variable hybrid_bus_type is defined in hw_params to indicate the
hybrid nature of the device.
Add HW params for WCN6750.

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.
