platform/x86/amd/pmc: Add Stellaris Slim Gen6 AMD to spurious 8042 quirks list
When WMAB is called to set the fan mode, the new mode is read from either
bits 0-1 or bits 4-5 (depending on the value of some other EC register).
Thus when WMAB is called with bits 4-5 zeroed and called again with
bits 0-1 zeroed, the second call undoes the effect of the first call.
This causes writes to /sys/devices/platform/lg-laptop/fan_mode to have
no effect (and causes reads to always report a status of zero).
Fix this by calling WMAB once, with the mode set in bits 0,1 and 4,5.
When the fan mode is returned from WMAB it always has this form, so
there is no need to preserve the other bits. As a bonus, the driver
now supports the "Performance" fan mode seen in the LG-provided Windows
control app, which provides less aggressive CPU throttling but louder
fan noise and shorter battery life.
Also, correct the documentation to reflect that 0 corresponds to the
default mode (what the Windows app calls "Optimal") and 1 corresponds
to the silent mode.

Currently, tpmi_get_logical_id() calls topology_physical_package_id()
to set the pkg_id of the info structure. Since some VM hosts assign non
contiguous package IDs, topology_physical_package_id() can return a
larger value than topology_max_packages(). This will result in an
invalid reference into tpmi_power_domain_mask[] as that is allocatead
based on topology_max_packages() as the maximum package ID.

On commit 9286dfd573 ("platform/x86: asus-wmi: Fix spurious rfkill on
UX8406MA"), Mathieu adds a quirk for the Zenbook Duo to ignore the code
0x5f (WLAN button disable). On that laptop, this code is triggered when
the device keyboard is attached.
On the ASUS ROG Z13 2025, this code is triggered when pressing the side
button of the device, which is used to open Armoury Crate in Windows.
As this is becoming a pattern, where newer Asus laptops use this keycode
for emitting events, let's convert the wlan ignore quirk to instead
allow emitting codes, so that userspace programs can listen to it and
so that it does not interfere with the rfkill state.
With this patch, the Z13 wil emit KEY_PROG3 and the Duo will remain
unchanged and emit no event. While at it, add a quirk for the Z13 to
switch into tablet mode when removing the keyboard.

Currently, the ignore_key_wlan quirk applies to keycodes 0x5D, 0x5E, and
0x5F. However, the relevant code for the Asus Zenbook Duo is only 0x5F.
Since this code is emitted by other Asus devices, such as from the Z13
for its ROG button, remove the extra codes before expanding the quirk.
For the Duo devices, which are the only ones that use this quirk, there
should be no effect.

Chris reported that even on a BIOS that has a new enough SMU F/W
version there is still a spurious IRQ1. Although the solution was
added to SMU F/W 64.66.0 it turns out there needs to be a matching
SBIOS change to activate it. Thus Linux shouldn't be avoiding the
IRQ1 workaround on newer SMU F/W because there is no indication the
BIOS change is in place.
Drop the match for 64.66.0+ and instead match all RN/CZN/BRC (they
all share same SMU F/W). Adjust the quirk infrastructure to allow
quirking the workaround on or off and also adjust existing quirks
to match properly.
Unfortunately this may cause some systems that did have the SBIOS
change in place to regress in keyboard wakeup but we don't have a
way to know. If a user reports a keyboard wakeup regression they can
run with amd_pmc.disable_workarounds=1 to deactivate the workaround
and share DMI data so that their system can be quirked not to use
the workaround in the upstream kernel.

The Dell SMBIOS driver uses the "id" field inside struct device for
prioritizing the WMI backend over the SMM backend. Because of this
the WMI backend modifies the "id" field of the underlying WMI device.
However the WMI core itself uses wdev->dev.id internally to track
device IDs, so modifying this value will result in a resource leak.
Fix this by not using the "id" field inside struct device for SMBIOS
prioritization. Instead extend struct smbios_device with a separate
"priority" field.
Tested on a Dell Inspiron 3505.

indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
