Unlike the event configuration which can be modified by MHI, the
channel and controller configurations are expected to be const. And
since they are not modified locally, constify them to prevent runtime
modification.
No functional changes, compile tested only.

Currently buf_len field of ath11k_mhi_config_qca6390 is assigned
with 0, making MHI use a default size, 64KB, to allocate channel
buffers. This is likely to fail in some scenarios where system
memory is highly fragmented and memory compaction or reclaim is
not allowed.
There is a fail report which is caused by it:

Actually those buffers are used only by QMI target -> host communication.
And for WCN6855 and QCA6390, the largest packet size for that is less
than 6KB. So change buf_len field to 8KB, which results in order 1
allocation if page size is 4KB. In this way, we can at least save some
memory, and as well as decrease the possibility of allocation failure
in those scenarios.

Every time the firmware boots we call ath11k_core_qmi_firmware_ready() which
ends up calling ath11k_thermal_register(). So we try to register thermal
devices multiple times. And when we power off the firmware during
suspend/hibernation (implemented in the next patch) we get a warning in resume:
hwmon hwmon4: PM: parent phy0 should not be sleeping
Workaround this similarly like ath11k_mac_register() does by testing
ATH11K_FLAG_REGISTERED.

We are seeing below warning in both reset and suspend/resume scenarios:

Both the firmware reset feature and the power management
suspend/resume feature share common power-down and power-up
functionality. One aspect of the power-up functionality is
the handling of the ATH11K_QMI_EVENT_FW_INIT_DONE event.
When this event is received, a call is made to
ath11k_hal_dump_srng_stats(), with the purpose to collect
information that may be useful in debugging the cause of a
firmware reset.
Unfortunately, since this functionality is shared between
both the firmware reset path and the power management
resume path, the kernel log is flooded with messages during
resume. Since these messages are not useful during resume,
and in fact can be confusing and can increase the time it
takes to resume, update the logic to only call
ath11k_hal_dump_srng_stats() during firmware reset.

There is no driver to match these two channels, so
remove them. This fixes warnings from MHI subsystem during suspend:

For non WoW suspend/resume, ath11k host powers down whole hardware
when suspend and powers up it when resume, the code path it goes
through is very like the ath11k reset logic.
In order to reuse that logic, rearrange IRQ handling in the reset
path.

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.

In ath11k_pci_probe() there is a switch statement that, based
upon the PCI device ID, assigns pci_ops. After the switch,
ath11k_pcic_register_pci_ops() is called to register the pci_ops.
Unfortunately, this registration is too late if any of the cases
in the switch need to perform operations that require the pci_ops
to already be registered. In particular, an upcoming patch for
QCA2066 needs to call ath11k_pcic_read32().
To address this issue, call ath11k_pcic_register_pci_ops() from
each case instead of doing so after the switch. That way the ops
will be registered if any subsequent operations within the case
processing require the ops to be present.

Provide address list to mac80211 so user doesn't need to specify addresses when
a second interface is added because the address can be allocated from the list
by mac80211.
The derived addresses have LAA (Local Administered Address) bit set, and only
the first byte is changed. Take the 00:03:7f:xx:xx:xx as example to derive:
addresses[0] is unchanged, it's still 00:03:7f:xx:xx:xx,
addresses[1] is 02:03:7f:xx:xx:xx,
addresses[2] is 12:03:7f:xx:xx:xx,
addresses[3] is 22:03:7f:xx:xx:xx,
addresses[4] is 32:03:7f:xx:xx:xx.
However as only 3 addresses are reported now, so addresses[3] and addresses[4]
aren't actually derived.

Add hardware parameter support_dual_stations to indicate whether 2 station
interfaces are supported. For chips which support this feature, limit total
number of AP interface and mesh point to 1. The max interfaces are 3 for such
chips.
The chips affected are:
QCA6390 hw2.0
WCN6855 hw2.0
WCN6855 hw2.1
Other chips are not affected.
For affected chips, remove radar_detect_widths because now
num_different_channels is set to 2. radar_detect_widths can be set only when
num_different_channels is 1, see mac80211 function wiphy_verify_combinations
for details. This means that in affectected chips DFS cannot be enabled in AP
mode.

Now that we do not use scan_flags directly with WMI_SCAN_XXX macros anymore but

This will prevent further problems as some entries in the scan_f_xxx bitfield
don't match their corresponding WMI_SCAN_XXX flags as seen in [1]

As discussed in [1] lets not use WMI_SCAN_XXX defines in combination with
scan_flags directly when setting scan params in struct scan_req_params but use
the underlying bitfield. This bitfield is then converted to WMI_SCAN_XXX when
filling the WMI command to send to the firmware.

Commit 6db6e70a17f6 ("wifi: ath12k: Introduce the container for mac80211

-ENOMEM was returned to the callers of ath12k_mac_allocate() whenever
ath12k_mac_hw_allocate() failed. Assign that value to ret to make sure
it is always initialized when used and clear up the warning.

Commit 9476cda44c13 ("wifi: ath11k: Consistently use ath11k_vif_to_arvif()")
previously replaced all open coding of the ath11k_vif_to_arvif()
functionality. Subsequently two more instances of open coding were
introduced, one in commit 92425f788fee ("wifi: ath11k: fill parameters for
vdev set tpc power WMI command") and one in commit 6f4e235be655 ("wifi:
ath11k: add parse of transmit power envelope element"), so fix those as
well.
No functional changes, compile tested only.

For P2P mode, the WLAN interface may be requested to remain on a
specific channel and then to send some management frames on that
channel. Now chananel frequency of wmi_mgmt_send_cmd is set as 0. As
a result, firmware may choose a default but wrong channel.
Fix it by assigning chanfreq field with the ROC channel frequency.
This change only applies to WCN7850, other chips are not affected.

In current code, when STA/P2P Client connect to AP/P2P GO, the WMI
command sequence is:
peer_create->vdev_start->vdev_up
And sequence of STA/P2P Client disconnect from AP/P2P GO is:
peer_delete->vdev_down->vdev_stop
This sequence of disconnect is not opposite of connect. For STA or P2P
GO, bss peer is not needed by firmware during handling vdev stop
command. So with this sequence, STA and P2P GO can work normally.
But for P2P Client, firmware needs bss peer in some functions during
handling vdev stop command. The opposite sequence of disconnect should
be:
vdev_down->vdev_stop->peer_delete
So change the sequence of disconnect as above opposite sequence for
WCN7850.

In current code, the management frames must be sent after vdev is started.
But for P2P device, vdev won't start until P2P negotiation is done. So
this logic doesn't make sense for P2P device.

The Notice of Absence (NoA) attribute is used by the P2P Group Owner to
signal its absence due to power save timing, concurrent operation, or
off-channel scanning. It is also used in the P2P Presence Request-Response
mechanism.
The NoA attribute shall be present in the P2P IE in the beacon frames
transmitted by a P2P Group Owner when a NoA schedule is being advertised,
or when the CTWindow is non-zero.
So add support to update P2P information after P2P GO is up through
event WMI_P2P_NOA_EVENTID, and always put it in probe resp.
Create p2p.c and p2p.h for P2P related functions and definitions.

Also, there is a bug that when mesh is enabled but ap is not enabled.
In this situation, the mesh's max_interface of interface combination

During calculate vdev_stats_id, will compare vdev_stats_id with
ATH12K_INVAL_VDEV_STATS_ID by '<='. If vdev_stats_id is relatively
small, then assign ATH12K_INVAL_VDEV_STATS_ID to vdev_stats_id.
This logic is incorrect. Firstly, should use '>=' instead of '<=' to
check if this u8 variable exceeds the max valid range.
Secondly, should use the maximum value as comparison value.
Correct comparison symbols and use the maximum value
ATH12K_MAX_VDEV_STATS_ID for comparison.

Currently, at the end of ath11k_mac_fill_reg_tpc_info(), the
reg_tpc_info struct is populated, including the following:
reg_tpc_info->is_psd_power = is_psd_power;
reg_tpc_info->eirp_power = eirp_power;
Kernel test robot complains on uninitialized symbol:
drivers/net/wireless/ath/ath11k/mac.c:7949
ath11k_mac_fill_reg_tpc_info() error: uninitialized symbol 'eirp_power'.
This is because there are some code paths that never set eirp_power, so
the assignment of reg_tpc_info->eirp_power can come from an
uninitialized variable. Functionally this is OK since the eirp_power
only has meaning when is_psd_power is true, and all code paths which set
is_psd_power to true also set eirp_power. However, to keep the robot
happy, always initialize eirp_power before use.

Currently in ath11k_peer_assoc_h_he() rx_mcs_80 and rx_mcs_160
are used to calculate max_nss, see
if (support_160)
max_nss = min(rx_mcs_80, rx_mcs_160);
else
max_nss = rx_mcs_80;
Kernel test robot complains on uninitialized symbols:
drivers/net/wireless/ath/ath11k/mac.c:2321 ath11k_peer_assoc_h_he() error: uninitialized symbol 'rx_mcs_80'.

drivers/net/wireless/ath/ath11k/mac.c:2323 ath11k_peer_assoc_h_he() error: uninitialized symbol 'rx_mcs_80'.
This is because there are some code paths that never set them, so
the assignment of max_nss can come from uninitialized variables.
This could result in some unknown issues since a wrong peer_nss
might be passed to firmware.
Change to initialize them to an invalid value at the beginning. This
makes sense because even max_nss gets an invalid value, due to either
or both of them being invalid, we can get an valid peer_nss with
following guard:
arg->peer_nss = min(sta->deflink.rx_nss, max_nss)

QMI PHY capability learn is used to get PHY count information to
support single/multi link operation (SLO/MLO) configuration. The
QCN9274 dualmac firmware currently do not support SLO/MLO, if two
PHYs are within the same chip. Due to this firmware crashes in
split-phy QCN9274, while bringing up AP with MLO parameter enabled
in QMI host capability request message.
The QMI PHY capability learn is not required for split-phy QCN9274,
if SLO/MLO is not supported within the same chip. Hence, disable QMI
PHY capability learn support in split-phy QCN9274.

QCN9274 can support single-PHY or split-PHY architecture. Currently,
only the single-PHY architecture is supported in ath12k.
The split-PHY QCN9274 requires different AMSS firmware binary
"amss_dualmac.bin".
Hence, add support to read board id from OTP. Based on board id
decide whether single-mac / dual-mac firmware needs to be downloaded
to the target. Also, update HW param max_radios to support split-PHY
in QCN9274.
Also, add new Firmware IE for firmware_N.bin
"ATH11K_FW_IE_AMSS_DUALMAC_IMAGE" to support dualmac QCN9274.

Currently, PCI read is failing for the registers belonging to
SECURITY_CONTROL_WLAN registers. These registers read is required
to read the board-id to identify the dual-mac QCN9274 hardware.
The failure is because, for these registers (SECURITY_CONTROL_WLAN)
offset, ath12k_pci_get_window_start() returns window_start as 0. Due
to this PCI read is done without PCI select window and with
window_start offset as 0.
Hence, fix PCI read and write by doing PCI select window and by using
the correct window_start offset - WINDOW_START for
SECURITY_CONTROL_WLAN registers.

When more than one pdev is supported in the chip/SoC, the packet
belonging to second pdev is given to first pdev due to not identifying
the MAC id in the WBM error path. So ping fails.
In WBM error path, src link id information not available in the
descriptor. So get this information from the msdu_end 64bit tag. It
is necessary to get the src link id to identify the MAC id in the
given chip. Then only we can pass the skb to the corresponding pdev.
The msdu_end 64bit tag is available only if compact Rx TLVs
descriptors are used. Thus, src link id is fetched correctly in WBM
error path when compact descriptors are in use.

Most of the RX descriptors fields are currently not used in the
ath12k driver. Hence add support to selectively subscribe to the
required quad words (64 bits) within msdu_end and mpdu_start of
rx_desc.
Add compact rx_desc structures and configure the bit mask for Rx TLVs
(msdu_end, mpdu_start, mpdu_end) via registers. With these registers
SW can configure to DMA the partial TLV struct to Rx buffer.
Each TLV type has its own register to configure the mask value.
The mask value configured in register will indicate if a particular
QWORD has to be written to rx buffer or not i.e., if Nth bit is enabled
in the mask Nth QWORD will be written and it will not be written if the
bit is disabled in mask. While 0th bit indicates whether TLV tag will be
written or not.
Advantages of Qword subscription of TLVs
- Avoid multiple cache-line misses as the all the required fields
of the TLV are within 128 bytes.
- Memory optimization as TLVs + DATA + SHINFO can fit in 2k buffer
even for 64 bit kernel.

With word mask subscription support, the rx_desc structure will
change. The fields in this structure rx_desc will be reduced to only
the required fields. To make word mask subscription changes compatible
with the older firmware version (firmware that does not support word
mask subscription), two different structures of rx_desc will be
required for the same hardware.
The hardware param hal_desc_sz value cannot be constant for the same
hardware. It depends on the size of rx_desc structure which may
change based on firmware capability to support word mask subscription.
Hence, remove hal_desc_sz from hardware param and add hal_rx_ops
to get the size of rx_desc in run time.

the required fields. To make word mask subscription changes compatible
with the older firmware version (firmware that does not support word
mask subscription), two different structures of rx_desc will be

Most of the hal_ops are directly related to rx_desc.
Hence, split hal_ops into operations that are independent of rx_desc
(hal_ops) and the operations that are directly dependent on rx_desc
(hal_rx_ops). These hal_rx_ops depend on both hardware and firmware
hence move them out of hw_params.

In segment memory mode, firmware allocates memory segments of size
2 MB. This 2 MB memory is used by firmware for the number of peers.
This number of peer is sent from host to firmware during WMI init
command. For single-phy the number of peers sent is
TARGET_NUM_PEERS_SINGLE = 529 (512 + 17). While for split-phy number
of peers sent to firmware is TARGET_NUM_PEERS_DBS = 2 *(512 + 17) =
1058. With this 1058 number of peers firmware is unable to allocate
memory in 2 MB segment and firmware crash is observed.
Hence, fix this firmware crash by reducing the number of stations
TARGET_NUM_STATIONS for split-phy.

Currently only one MHI device is registered successfully on platform
having two or more identical MHI devices. This is beacuse QMI service
runs with identical QRTR node ID. And, qrtr-lookup cannot register
more than one QMI service with identical node ID.
Hence, generate a unique QRTR instance ID from PCIe domain number and
bus number. QMI allows node id to be written on scratch register.
Add logic to write QRTR node id to the register. It is available for
firmware to uniquely identify an instance.

In QCN9274, RX packet's multicast and broadcast(MCBC) flag is fetched
from RX descriptor's msdu_end info5 member but it is not correct
for QCN9274. Due to this with encryption, ARP request packet is wrongly
marked as MCBC packet and it is sent to mac80211 without setting
RX_FLAG_PN_VALIDATED & RX_FLAG_DECRYPTED flag. This results in packet
getting dropped in mac80211. Hence ping initiated from station to AP
fails.
Fix this by fetching correct MCBC flag in case of QCN9274.
For QC9274 MCBC flag should be fetched from RX descriptor's mpdu_start
info6 member.
