For now, the WH and PE radios require the same config as
FM, so just add a #define for those instead of copying
the data. Since this is true, Sc/Dr/Br all used the same
configs for all RF types, but that's confusing, so now
use the defined WH/PE names for the correct combinations.
We can also now enable the unit test that ensures we have
no duplicate RF configs.

In some older devices, the min/max firmware API supported by
the driver depends on the specific device, when sharing the
the same MAC (config). For most newer devices, it really is
dependent on the MAC instead, since the firmware was frozen
for certain MAC types. However, in the future we expect also
freezes for RF types there.
To handle this most generally, add an API min/max to the MAC
config and then use the narrowest range prescribed by both,
if set.
For the newer MACs since 9000, move the configuration, there
was only a freeze on MAC+RF lines so far.

There are a number of MAC parameters that are in the iwl_cfg

This isn't necessary, there are many more of those than MACs,
so move (most of) the data into the MAC family config struct.
Note that DCCM information remains for use by older devices,

The driver must not hold the wiphy mutex when unregistering the thermal
devices. Do not hold the lock for the call to iwl_mld_thermal_exit and
only do a lock/unlock to cancel the ct_kill_exit_wk work.
The problem is that iwl_mld_tzone_get_temp needs to take the wiphy lock
while the thermal code is holding its own locks already. When
unregistering the device, the reverse would happen as the driver was
calling thermal_cooling_device_unregister with the wiphy mutex already
held.
It is not likely to trigger this deadlock as it can only happen if the
thermal code is polling the temperature while the driver is being
unloaded. However, lockdep reported it so fix it.

If there is an ongoing scan that lasts long, the MPDU counters may not
increase enough due the device being busy with scanning and not
because we are in a low throughput scenario.
In that case we don't want to block EMLSR.
Instead, stop checking the counters from the moment we started
scanning, and when the scan ends - clear the counters and schedule a
check in 5 seconds, as usual.
Note that this is only done for regular scan since MLO scan is too short
to affect the counters, and scheduled scan is mainly used when we are
not connected.
Also note that we only stop checking whether to block EMLSR, and not if to

Since there are two bytes hole in struct iwl_dev_info, add
a subdev_mask to match with. Also, since the PCI IDs list
needs to match first, and the dev-info list is matched from
the bottom up, remove unnecessary entries.
With this, even though there are new entries from previous
changes, the overall size is slightly reduced.

A long time ago, when transport vs. device configs were
introduced, we wanted to eventually have a list of PCI
IDs and a separate list of devices, but for simplicity
embedded the transport config in the whole config, and
it all got confusing.
Finish splitting that out. Doing so requires having more
IWL_DEV_INFO() entries, but the whole trans/cfg aliasing
goes away and the code becomes a lot simpler.

Remove the erroneously named IWL_DEVICE_BZ_COMMON macro
from the Sc file and fix some indentation. Also bump the

It's not clear that it makes sense to have any matches
for IWL_CFG_ANY for this bit, but let's assume for now
that this makes sense. Then, it's clearer to call this
BW_NOT_LIMITED rather than BW_NO_LIMIT, since the last

The BW limit, cores and RF ID are matched in the subdevice ID,
so it doesn't really make sense to have both SUBDEV() match and
a match on any of those three. In particular, for Killer devices
the subdevice ID doesn't even follow the layout, so no matching
should be on those three values at all, only with SUBDEV().
Change the logic around the BW limit to have it more like all
the other things: only a bw_limit match in the dev_info, and
put the actual bandwidth into struct iwl_cfg. This duplicates a
number of those values, but that way the logic is clearer.
Add a test that checks that the three matches mentioned above
are not used in conjunction with SUBDEV(), and check that if
the bw_limit is matched, a BW limit is provided in the config.
Also check that the "Killer" devices have a SUBDEV() match.

When a soft AP is started, it may not use the full configured
bandwidth (e.g. if no station is connected). As a result, the
responder will not support the configured bandwidth. Since the
responder supports ranging with unassociated stations, there is
no indication to the driver when the full bandwidth should be enabled.
Fix it by configuring the AP to always use the full bandwidth when a
responder is supported.

For the upcoming SC hardware, a new reset mode "(silent) TOP
reset" will be available. When BT initiates that reset, it'll
negotiate with the WiFi firmware which makes it appear to the
driver as the reset interrupt. To distinguish it from all the
other reasons for the reset interrupt, there's (now) a status
field in CSR 0x110.
Implement the part of TOP reset where we react to BT doing it.
This requires disambiguating the interrupt, depending on the
state of the device, since we can even get TOP reset from BT
while waiting for the reset handshake.
If TOP reset is done by BT while we're not trying to do reset
anyway, then simply reprobe, since we cannot keep the state
of the device as it's being reset, after waiting the needed
180ms to let the device reset/settle.

From the moment that we have ALIVE, we can receive notification that
are handled asynchronously.
Some notifications (for example iwl_rfi_support_notif) requires an
operational FW. So we need to make sure that they were handled in
iwl_op_mode_mld_start before we stop the FW. Flush the async_handlers_wk
there to achieve that.
Also, if loading the FW in op mode start failed, we need to cancel
these notifications, as they are from a dead FW.
More than that, not doing so can cause us to access freed memory
if async_handlers_wk is executed after ieee80211_free_hw is called.
Fix this by canceling all async notifications if a failure occurred in
init (after ALIVE).

If iwl_mld_load_fw failed, we call iwl_mld_stop_fw which does, among the
others, iwl_trans_stop_device. But this is already called from
iwl_mld_load_fw's error path.
Since we do need the other stuff of iwl_mld_stop_fw to be done also in
the error path of iwl_mld_load_fw, just call it there.
This also makes the call to iwl_fw_flush_dumps in
iwl_mld_op_mope_start redundant, since it is the same as iwl_fw_dbg_stop_sync.

so do the handshake in the non-split case when asked for.

The C sequence points are complicated things, and gcc-15 has apparently
added a warning for the case where an object is both used and modified
multiple times within the same sequence point.
That's a great warning.
Or rather, it would be a great warning, except gcc-15 seems to not
really be very exact about it, and doesn't notice that the modification
are to two entirely different members of the same object: the array
counter and the array entries.
So that seems kind of silly.
That said, the code that gcc complains about is unnecessarily
complicated, so moving the array counter update into a separate
statement seems like the most straightforward fix for these warnings:
drivers/net/wireless/intel/iwlwifi/mld/d3.c: In function ‘iwl_mld_set_netdetect_info’:
drivers/net/wireless/intel/iwlwifi/mld/d3.c:1102:66: error: operation on ‘netdetect_info->n_matches’ may be undefined [-Werror=sequence-point]

1120 | match->channels[match->n_channels++] =
| ~~~~~~~~~~~~~~~~~^~
side note: the code at that second warning is actively buggy, and only
works on little-endian machines that don't do strict alignment checks.
The code casts an array of integers into an array of unsigned long in
order to use our bitmap iterators. That happens to work fine on any
sane architecture, but it's still wrong.
This does *not* fix that more serious problem. This only splits the two
assignments into two statements and fixes the compiler warning. I need
to get rid of the new warnings in order to be able to actually do any
build testing.

The reset handshake attempts to kill the firmware, and it'll go
into a pretty much dead state once we do that. However, if it
times out, then we'll attempt to dump the firmware to be able
to see why it didn't respond. During this dump, we cannot treat
it as if it was still running, since we just tried to kill it,
otherwise dumping will attempt to send a DBGC stop command. As
this command will time out, we'll go into a reset loop.
For now, fix this by setting the trans->state to say firmware
isn't running before doing the reset handshake. In the longer
term, we should clean up the way this state is handled.
It's not entirely clear but it seems likely that this issue was
introduced by my rework of the error handling, prior to that it
would've been synchronous at that point and (I think) not have
attempted to reset since it was already doing down.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create a new tagged `struct iwl_tx_cmd_hdr`. This structure
groups together all the members of the flexible `struct iwl_tx_cmd`
except the flexible array.
As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct iwl_tx_cmd` to `struct iwl_tx_cmd_hdr`.
We also want to ensure that when new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.
This approach avoids having to implement `struct iwl_tx_cmd_hdr`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
So, with these changes, fix the following warnings:
drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2315:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

iwl_mld_remove_link removes the link from both the FW and from the
driver.
If removing it from the FW failed, we assume that the FW is
dead anyway and remove it from the driver as well.
On the other hand, we still return an error value, indicating the caller
(i.e. mac80211) that the link couldn't be removed - while it was
actually removed.
Later, mac80211 might tell the driver again to remove that link,
and then the driver will warn that it doesn't exist.
Fix this by making iwl_mld_remove_link a void function.

OMI will only apply if the original bandwidth is > 80 MHz.) Fix
this by making that selection contingent on AP mode. Refactor

Since iwlmld claims wiphys to be self-managed, it needs to
have a regdomain registered before the wiphy is registered
to avoid issues when trying to get the regdomain, e.g. via
"iw phy phy0 reg get".
Move the initialization early, on every FW start not just
when starting to really operate it. This also requires the
self-managed flag to be set early.

The code was calling ieee80211_iterate_interfaces, however that
takes a lock of iflist_mtx, which must not be taken recursively. Fix
this by using the appropriate _mtx version that asserts that the wiphy

If the user disables power save of a vif that didn't have it enabled
(for example before association), mac80211 will not notify the driver
with BSS_CHANGED_PS. This will cause the driver to not update the
device-level power save to disabled.
Fix this by checking the vif's power save status upon authorization, and
stop considering the vif's power save status on disassociation.

Corrected the bit size calculation in the for_each_set_bit macro in

sizeof(dyn_status), which only accounts for the number of bytes.
This has been updated to TAS_DYNA_STATUS_MAX to ensure the loop iterates

The FW is now responsible of determining the SMPS mode.
If the user disabled power save in a certain vif, we send the vif-level
power command to clear out the POWER_FLAGS_POWER_MANAGEMENT_ENA_MSK bit
for that vif.
But erroneously, the FW checks DEVICE_POWER_FLAGS_POWER_SAVE_ENA_MSK in
the device-level command to determine the SMPS mode.
To W/A this, send also the device-level command when the power save of a
vif changes, and disable power save if there is any vif that has power
save disabled.

The order of actions taken for debug was implemented incorrectly.
Now we implemented the dump split and do the FW reset only in the
middle of the dump (rather than the FW killing itself on error.)
As a result, some of the actions taken when applying the config
will now crash the device, so we need to fix the order.

If the restart work happens to run after the opmode left
(i.e. called iwl_trans_op_mode_leave), then the opmode memory (including
its mutex) is likely to be freed already, and trans->opmode is NULL.
Although the hw is stopped in that stage, which means that this restart
got aborted (i.e. STATUS_RESET_PENDING will be cleared),
it still can access trans->opmode (NULL pointer dereference)
or the opmodes memory (which is freed).
Fix this by canceling the restart wk in iwl_trans_op_mode_leave.
Also make sure that the restart wk is really aborted.

When MSI-X is not enabled, we mask all the interrupts in the interrupt
handler and re-enable them when the interrupt thread runs. If
STATUS_INT_ENABLED is not set, we won't re-enable in the thread.
In order to get the ALIVE interrupt, we allow the ALIVE interrupt
itself, and RX as well in order to receive the ALIVE notification (which
is received as an RX from the firmware.
The problem is that STATUS_INT_ENABLED is clear until the op_mode calls
trans_fw_alive which means that until trans_fw_alive is called, any
notification from the firmware will not be received.
This became a problem when we inserted the pnvm_load exactly between the
ALIVE and trans_fw_alive.
Fix that by calling trans_fw_alive before loading the PNVM. This will
allow to get the notification from the firmware about PNVM load being
complete and continue the flow normally.
This didn't happen on MSI-X because we don't disable the interrupts in
the ISR when MSI-X is available.
The error in the log looks like this:
iwlwifi 0000:00:03.0: Timeout waiting for PNVM load!
iwlwifi 0000:00:03.0: Failed to start RT ucode: -110
