0b6e6e149c platform/x86/amd: pmc: Read SMU version during suspend on Cezanne systems
commit b0c07116c8 ("platform/x86: amd-pmc: Avoid reading SMU version at
probe time") adjusted the behavior for amd-pmc to avoid reading the SMU
version at startup but rather on first use to improve boot time.

However the SMU version is also used to decide whether to place a timer
based wakeup in the OS_HINT message. If the idlemask hasn't been read
before this message was sent then the SMU version will not have been
cached.

Ensure the SMU version has been read before deciding whether or not to
run this codepath.

a10d50983f platform/x86: thinkpad_acpi: Fix reporting a non present second fan on some models
thinkpad_acpi was reporting 2 fans on a ThinkPad T14s gen 1, even though
the laptop has only 1 fan.

The second, not present fan always reads 65535 (-1 in 16 bit signed),
ignore fans which report 65535 to avoid reporting the non present fan.

60ac35bf6b Interrupt subsystem updates:
- Core code:
 
     - Provide a generic wrapper which can be utilized in drivers to handle
       the problem of force threaded demultiplex interrupts on RT enabled
       kernels. This avoids conditionals and horrible quirks in drivers all
       over the place.
 
     - Fix up affected pinctrl and GPIO drivers to make them cleanly RT safe.
 
   - Interrupt drivers:
 
     - A new driver for the FSL MU platform specific MSI implementation.
 
     - Make irqchip_init() available for pure ACPI based systems.
 
     - Provide a functional DT binding for the Realtek RTL interrupt chip.
 
     - The usual DT updates and small code improvements all over the place.

The for_each_acpi_consumer_dev() takes a reference to the iterator
and if we break a loop we must drop that reference. This usually
happens when error handling is involved. However it's not the case
for skl_int3472_fill_clk_pdata().

Don't leak reference on error by dropping it properly.

The idle mask is dumped during the "prepare" and "restore" stage
right now, which helps to demonstrate issues only related to the
first s2idle entry.

If the system has entered s2idle once, but was woken up never
breaking the s2idle loop but also never went back to sleep we
might still have another issue to deal with however.

Move the dynamic debugging message here so that we'll catch it on
each iteration.

22ee98cb69 platform/x86/amd/pmf: install notify handler after acpi init
It is observed that when thinkpad_acpi driver loads before amd-pmf
driver, thinkpad_acpi driver sends the AMT "on" event and the request
immediately will be part of the PMF BIOS "pending requests".

With the current amd-pmf code, as soon as the amd-pmf driver gets
probed, it calls apmf_acpi_init() where the notify handler will be
installed. Handler callback would call amd_pmf_handle_amt() where the
amd_pmf_set_automode() shall update the auto-mode thermals.
In this case, the auto-mode config_store shall have "zeros", as the
auto mode init gets called during the later stage.

To fix this, change the order of the acpi notifer install and call it
after the auto mode initialization is done.

Currently, we only support passing a single gpiod_lookup_table as part

assumption that each TPS68470 device will only support a single
sensor, which does not hold true.

having a gpiod_lookup_table, and opportunistically add the lookup
table for the Surface Go line's IR camera.

In commit b83e2b3067 ("ACPI: scan: Add function to fetch dependent

declare itself dependent on another ACPI device in the _DEP method.
One assumption in that patch was that there would only be a single
consuming device, but this has not held.

Replace that function with a new function that fetches the next consumer
of a supplier device. Where no "previous" consumer is passed in, it
behaves identically to the original function.

PMF dynamically manages system power limits and fan policy based on system
power trends which is representative of workload trend.

Static slider and CnQF controls are mutually exclusive for system power
budget adjustments. CnQF supports configurable number of modes which can
be unique for AC and DC. Every mode is representative of a system state
characterized by unique steady state and boost behavior.

OEMs can configure the different modes/system states and how the
transition to a mode happens. Whether to have CnQF manage system power
budget dynamically in AC or DC or both is also configurable. Mode changes
due to CnQF don't result in slider position change.

The default OEM values are obtained after evaluating the PMF ACPI function
idx 11 & 12 for AC and DC respectively. Whether to turn ON/OFF by default
is guided by a "flag" passed by the OEM BIOS.

3cb1f40dfd drivers/platform: toshiba_acpi: Call HCI_PANEL_POWER_ON on resume on some models
Some Toshibas have a broken acpi-video interface for brightness control, so
far these have been using a special workaround in drivers/acpi/acpi_video.c
which gets activated by the disable_backlight_sysfs_if module-param/quirks.

The recent x86/acpi backlight refactoring has broken this workaround:
1. This workaround relies on acpi_video_get_backlight_type() returning
   acpi_video so that the acpi_video code actually runs; and
2. this relies on the actual native GPU driver to offer the sysfs
   backlight interface to userspace.

After the refactor this breaks since the native driver will no
longer register its backlight-device if acpi_video_get_backlight_type()
does not return native and making it return native breaks 1.

Keeping the acpi_video backlight handling on resume active, while not
using it to set the brightness, is necessary because it does a _BCM
call on resume which is necessary to turn the panel back on on resume.

Looking at the DSDT shows that this _BCM call results in a Toshiba
HCI_SET HCI_LCD_BRIGHTNESS call, which turns the panel back on.

This commit makes toshiba_acpi do a HCI_SET HCI_PANEL_POWER_ON call
on resume on the affected models, so that the (now broken)
acpi_video disable_backlight_sysfs_if workaround will no longer
be necessary.

Note this uses HCI_PANEL_POWER_ON instead of HCI_LCD_BRIGHTNESS
to avoid changing the configured brightness level.

8ef5db9eb0 platform/x86: Battery charge mode in toshiba_acpi (sysfs)
This commit adds the ACPI battery hook which in turns adds the sysfs
entries.

Because the Toshiba laptops only support two modes (eco or normal), which
in testing correspond to 80% and 100% we simply round to the nearest
possible level when set.

It is possible that Toshiba laptops other than the Z830 has different set
points for the charging. If so, a quirk table could be introduced in the
future for this. For now, assume that all laptops that support this feature
work the same way.

Tested on a Toshiba Satellite Z830.

89655fbb39 platform/x86: Battery charge mode in toshiba_acpi (internals)
This commit adds the internal functions to control the Toshiba laptop.

Unlike for example ThinkPads where this control is granular here it is
just off/on. When off it charges to 100%. When on it charges to about 80%.

Controlling this setting is done via HCI register 0x00ba. Setting to value
1 will result in limiting the charing to 80% of the battery capacity,
while setting it to 0 will allow charging to 100%.

Reading the current state is a bit weird, and needs a 1 set in the last
position of the query for whatever reason. In addition, the read may
return 0x8d20 (Data not available) rarely, so a retry mechanism is needed.

According to the Windows program used to control the feature the setting
will not take effect until the battery has been discharged to around 50%.
However, in my testing it takes effect as soon as the charge drops below
80%. On Windows Toshiba branded this feature as "Eco charging".

f98d67ac42 platform/x86: p2sb: Fix UAF when caller uses resource name
We have to copy only selected fields from the original resource.
Because a PCI device will be removed immediately after getting
its resources, we may not use any allocated data, hence we may
not copy any pointers.

Consider the following scenario:

  1/ a caller of p2sb_bar() gets the resource;

  2/ the resource has been copied by platform_device_add_data()
     in order to create a platform device;

  3/ the platform device creation will call for the device driver's
     ->probe() as soon as a match found;

  4/ the ->probe() takes given resources (see 2/) and tries to
     access one of its field, i.e. 'name', in the
     __devm_ioremap_resource() to create a pretty looking output;

  5/ but the 'name' is a dangling pointer because p2sb_bar()
     removed a PCI device, which 'name' had been copied to
     the caller's memory.

  6/ UAF (Use-After-Free) as a result.

Kudos to Mika for the initial analisys of the issue.

134038b075 platform/x86: wmi: Allow duplicate GUIDs for drivers that use struct wmi_driver
The WMI subsystem in the kernel currently tracks WMI devices by
a GUID string not by ACPI device.  The GUID used by the `wmi-bmof`
module however is available from many devices on nearly every machine.

This originally was thought to be a bug, but as it happens on most
machines it is a design mistake.  It has been fixed by tying an ACPI
device to the driver with struct wmi_driver. So drivers that have
moved over to struct wmi_driver can actually support multiple
instantiations of a GUID without any problem.

Add an allow list into wmi.c for GUIDs that the drivers that are known
to use struct wmi_driver.  The list is populated with `wmi-bmof` right
now. The additional instances of that in sysfs with be suffixed with -%d

acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers

Move all the acpi_backlight=[vendor|native] quirks from samsung-laptop to

Note the X360 -> acpi_backlight=native quirk is not moved because that

2603c681e0 platform/x86: asus-wmi: Drop DMI chassis-type check from backlight handling
Remove this check from the asus-wmi backlight handling:

	/* Some Asus desktop boards export an acpi-video backlight interface,
	   stop this from showing up */
	chassis_type = dmi_get_system_info(DMI_CHASSIS_TYPE);
	if (chassis_type && !strcmp(chassis_type, "3"))
		acpi_video_set_dmi_backlight_type(acpi_backlight_vendor);

This acpi_video_set_dmi_backlight_type(acpi_backlight_vendor) call must be
removed because other changes in this series change the native backlight
drivers to no longer unconditionally register their backlight. Instead
these drivers now do this check:

        if (acpi_video_get_backlight_type(false) != acpi_backlight_native)
                return 0; /* bail */

So leaving this in place can break things on laptops with a broken
DMI chassis-type, which would have GPU native brightness control before
the addition of the acpi_video_get_backlight_type() != native check.

Removing this should be ok now, since the ACPI video code has improved
heuristics for this itself now (which includes a chassis-type check).

0172df18dc platform/x86: acer-wmi: Move backlight DMI quirks to acpi/video_detect.c
Move the backlight DMI quirks to acpi/video_detect.c, so that
the driver no longer needs to call acpi_video_set_dmi_backlight_type().

acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers
already being registered even though they should not.

Note that even though the DMI quirk table name was video_vendor_dmi_table,
5/6 quirks were actually quirks to use the GPU native backlight.

These 5 quirks also had a callback in their dmi_system_id entry which
disabled the acer-wmi vendor driver; and any DMI match resulted in:

	acpi_video_set_dmi_backlight_type(acpi_backlight_vendor);

which disabled the acpi_video driver, so only the native driver was left.
The new entries for these 5/6 devices correctly marks these as needing
the native backlight driver.

Also note that other changes in this series change the native backlight
drivers to no longer unconditionally register their backlight. Instead
these drivers now do this check:

	if (acpi_video_get_backlight_type(false) != acpi_backlight_native)
		return 0; /* bail */

which without this patch would have broken these 5/6 "special" quirks.

Since I had to look at all the commits adding the quirks anyways, to make
sure that I understood the code correctly, I've also added links to
the various original bugzillas for these quirks to the new entries.

a2ed70d0ec platform/x86: toshiba_acpi: Stop using acpi_video_set_dmi_backlight_type()
acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers
already being registered even though they should not.

In case of the acpi_video backlight, acpi_video_set_dmi_backlight_type()
actually calls acpi_video_unregister_backlight() since that is often
probed earlier, leading to userspace seeing the acpi_video0 class
device being briefly available, leading to races in userspace where
udev probe-rules try to access the device and it is already gone.

In case of toshiba_acpi there are no DMI quirks to move to
acpi/video_detect.c, but it also (ab)uses it for transflective
displays. Adding transflective display support to video_detect.c would
be quite involved. But luckily there are only 2 known models with
a transflective display, so we can just add DMI quirks for those.

647e82dbf8 platform/x86: p2sb: Fix UAF when caller uses resource name
We have to copy only selected fields from the original resource.
Because a PCI device will be removed immediately after getting
its resources, we may not use any allocated data, hence we may
not copy any pointers.

Consider the following scenario:

  1/ a caller of p2sb_bar() gets the resource;

  2/ the resource has been copied by platform_device_add_data()
     in order to create a platform device;

  3/ the platform device creation will call for the device driver's
     ->probe() as soon as a match found;

  4/ the ->probe() takes given resources (see 2/) and tries to
     access one of its field, i.e. 'name', in the
     __devm_ioremap_resource() to create a pretty looking output;

  5/ but the 'name' is a dangling pointer because p2sb_bar()
     removed a PCI device, which 'name' had been copied to
     the caller's memory.

  6/ UAF (Use-After-Free) as a result.

Kudos to Mika for the initial analisys of the issue.

- Add lock() / unlock() at the beginning / end of
  mlxreg_lc_event_handler() and remove locking from
  mlxreg_lc_power_on_off() and mlxreg_lc_enable_disable()
- Add locked version of mlxreg_lc_state_update() -
  mlxreg_lc_state_update_locked() for using outside
  mlxreg_lc_event_handler().

(2) Remove redundant NULL check for of if 'data->notifier'.

c3b82d26bc platform/x86: acer-wmi: Acer Aspire One AOD270/Packard Bell Dot keymap fixes
2 keymap fixes for the Acer Aspire One AOD270 and the same hardware
rebranded as Packard Bell Dot SC:

1. The F2 key is marked with a big '?' symbol on the Packard Bell Dot SC,
this sends WMID_HOTKEY_EVENTs with a scancode of 0x27 add a mapping
for this.

2. Scancode 0x61 is KEY_SWITCHVIDEOMODE. Usually this is a duplicate
input event with the "Video Bus" input device events. But on these devices
the "Video Bus" does not send events for this key. Map 0x61 to KEY_UNKNOWN
instead of using KE_IGNORE so that udev/hwdb can override it on these devs.

83ac7a1c2e platform/x86: msi-laptop: Fix old-ec check for backlight registering
Commit 2cc6c71779 ("msi-laptop: Port to new backlight interface
selection API") replaced this check:

	if (!quirks->old_ec_model || acpi_video_backlight_support())
		pr_info("Brightness ignored, ...");
	else
		do_register();

With:

	if (quirks->old_ec_model ||
	    acpi_video_get_backlight_type() == acpi_backlight_vendor)
		do_register();

But since the do_register() part was part of the else branch, the entire
condition should be inverted.  So not only the 2 statements on either
side of the || should be inverted, but the || itself should be replaced
with a &&.

In practice this has likely not been an issue because the new-ec models
(old_ec_model==false) likely all support ACPI video backlight control,
making acpi_video_get_backlight_type() return acpi_backlight_video
turning the second part of the || also false when old_ec_model == false.
