To handle the Lenovo unexpected wakeup issue [1], previously we revert
commit 166a490f59ac ("wifi: ath11k: support hibernation"). However we
need to bring it back, of course with additional changes such that Lenovo
machines would not break.

For suspend (S3), as those machines work well in WoWLAN mode, the thought
here is that we put WLAN target into WoWLAN mode on those machines while
into non-WoWLAN mode (which is done in the reverted commit) on other
machines. This requires us to identify Lenovo machines from others. For
that purpose, read machine info from DMI interface, match it against all
known affected machines. If there is a match, choose WoWLAN suspend mode,
else choose non-WoWLAN mode. This is done in patches [1 - 4/6]

For hibernation (S4), non-WoWLAN mode is chosen for all machines. The
unexpected wakeup issue should not happen in this mode, since WLAN target
power is cut off. To know if the system is going to suspend or to
hibernate, register a notifier such that kernel can notify us of such
infomation. This is done in patch [5/6]

The last patch bring the reverted "wifi: ath11k: restore country code
during resume" commit back.

To handle the Lenovo unexpected wakeup issue [1], previously we revert
commit 166a490f59ac ("wifi: ath11k: support hibernation"). So currently
WLAN target is put into WoWLAN mode during suspend. This is a temporary
solution as it does not work on machines where WLAN power is cut off.

The thought here is that we do WoWLAN suspend on Lenovo machines while
do non-WoWLAN suspend (which is done in the reverted commit) on other
machines. This requires us to identify Lenovo machines from others.
For that purpose, read board vendor and product name from DMI interface,
match it against all known affected machines. If there is a match, choose
WoWLAN suspend mode, else choose non-WoWLAN mode. Save the mode in ab
for later reference.

Currently ath11k_core_suspend() and ath11k_core_resume() have the same
check before going on. In upcoming patches the check is needed by some
newly added functions as well.

To avoid duplicate code, introduce a new helper
ath11k_core_continue_suspend_resume() which does such check internally.
Callers can decide whether to go on based on its return value.

Due to [1] we currently put WLAN target into WoWLAN mode regardless of
machine models. In upcoming patches we will support another mode, and
finally which mode is chosen depends on the exact machine model.

To prepare for such change, refactor the actual WoWLAN stuff in
ath11k_core_suspend() into a new helper ath11k_core_suspend_wow(), this
increase the code readability when the new suspend mode is added in
upcoming patches.

Same change applies to ath11k_core_resume();

Previously commit 166a490f59ac ("wifi: ath11k: support hibernation") was
reverted due to [1], so currently we only support WoWLAN mode suspend.
This works well in scenarios where WLAN power is sustained during suspend,
however breaks in those where power is cut off.

This change basically brings the reverted commit back, but differs in that
we decide based on the PM policy to choose WoWLAN mode suspend or the
non-WoWLAN mode. As stated in the previous patch for now the PM policy is
determined based on machine models. That said we will choose WoWLAN mode
suspend if we are running on machines listed in ath11k_pm_quirk_table,
otherwise we choose the other one.

Now WoWLAN mode is chosen for those machines listed in the quirk table.
This works for suspend (S3) but breaks for hibernation (S4), because
WoWLAN mode requires WLAN power to be sustained, which is not the case
during hibernation. For hibernation, the default mode should be used.

Register a PM notifier with which kernel can notify us of the actual PM
operation: if system is going to suspend, the original PM policy is
honored; while if it is hibernation, overwrite it with default policy.

To summarize: for suspend (S3), WoWLAN mode is chosen for machines listed
in the quirk table, non-WoWLAN mode for others; for hibernation (S4),
non-WoWLAN mode is chosen for all.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30

Thanks, this helps understand the issue.

And BTW, WLAN firmware is missing in your setup, you may get them from linux firmware repo
to avoid this issue.

This is still a driver bug that needs to be fixed. I just sent a fix a
here:

	https://lore.kernel.org/lkml/20250624082022.15469-1-johan+linaro@kernel.org/

Also note that there is no board file for the CRD in linux-firmware
(yet, see [1]), but apparently that is not enough to cause probe to fail
(unlike completely missing firmware).

WFIW, I'm not seeing this with 6.16-rc2 (which has this patch) on either
the X13s or sc8280xp-crd (ath11k now fails to resume on the latter
because of missing regulatory data, but that appears to be a separate
regression).

Scratch that bit about failing to resume, it's just a warning that's
new.

Do you have CONFIG_DEBUG_NOTIFIERS?

Nope. Would have been useful to mention in your report.

But I'm not seeing the warning with 6.16-rc2 with that option enabled
either.

Ah, maybe in linux-next, it was only merged to mainline for 6.16-rc1.

This reverts commit d3e154d7776ba57ab679fb816fb87b627fba21c9.

With non-WoWLAN suspend support brought back, commit 7f0343b7b871 ("wifi:
ath11k: restore country code during resume") needs to be brought back
as well.
