Register a privacy-screen device on laptops with a privacy-screen,
this exports the PrivacyGuard features to user-space using a
standardized vendor-agnostic sysfs interface. Note the sysfs interface
is read-only.
Registering a privacy-screen device with the new privacy-screen class
code will also allow the GPU driver to get a handle to it and export
the privacy-screen setting as a property on the DRM connector object
for the LCD panel. This DRM connector property is a new standardized
interface which all user-space code should use to query and control
the privacy-screen.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.
So, to avoid open-coded arithmetic in the kzalloc() call inside the
create_attr_set() function the code must be refactored. Using the
struct_size() helper is the fast solution but it is better to switch
this code to common use of attributes.
Then, remove all the custom code to manage hotkey attributes and use the
attribute_group structure instead, refactoring the code accordingly.
Also, to manage the optional hotkey attributes (hotkey_tablet_mode and
hotkey_radio_sw) use the is_visible callback from the same structure.
Moreover, now the hotkey_init_tablet_mode() function never returns a
negative number. So, the check after the call can be safely removed.

Various 360 degree hinges (yoga) style 2-in-1 devices use 2 accelerometers
to allow the OS to determine the angle between the display and the base of
the device.
On Windows these are read by a special HingeAngleService process which
calls undocumented ACPI methods, to let the firmware know if the 2-in-1 is
in tablet- or laptop-mode. The firmware may use this to disable the kbd and
touchpad to avoid spurious input in tablet-mode as well as to report
SW_TABLET_MODE info to the OS.
Since Linux does not call these undocumented methods, the SW_TABLET_MODE
info reported by various pdx86 drivers is incorrect on these devices.
Before this commit the intel-hid and thinkpad_acpi code already had 2
hardcoded checks for ACPI hardware-ids of dual-accel sensors to avoid
reporting broken info.
And now we also have a bug-report about the same problem in the intel-vbtn
code. Since there are at least 3 different ACPI hardware-ids in play, add
a new dual_accel_detect() helper which checks for all 3, rather then
adding different hardware-ids to the drivers as bug-reports trickle in.
Having shared code which checks all known hardware-ids is esp. important
for the intel-hid and intel-vbtn drivers as these are generic drivers
which are used on a lot of devices.
The BOSC0200 hardware-id requires special handling, because often it is
used for a single-accelerometer setup. Only in a few cases it refers to
a dual-accel setup, in which case there will be 2 I2cSerialBus resources
in the device's resource-list, so the helper checks for this.

On recent Thinkpad platforms it was reported that temp sensor 11 was
always incorrectly displaying 66C. It turns out the reason for this is
that this location in EC RAM is not a temperature sensor but is the
power supply ID (offset 0xC2).
Based on feedback from the Lenovo firmware team the EC RAM version can
be determined and for the current version (3) only the 0x78 to 0x7F
range is used for temp sensors. I don't have any details for earlier
versions so I have left the implementation unaltered there.
Note - in this block only 0x78 and 0x79 are officially designated (CPU &
GPU sensors). The use of the other locations in the block will vary from
platform to platform; but the existing logic to detect a sensor presence
holds.

"balanced" when /sys/bus/platform/devices/thinkpad_acpi/dytc_lapmode

stuck at 0 for aprox. 30 minutes even if the laptop is used on a lap.
Disabling CQL (when enabled) before issuing the DYTC_CMD_RESET to get
back to balanced mode and re-enabling it afterwards again, like the

this.

On many recent ThinkPad laptops, there's a new LED next to the ESC key,
that indicates the FnLock status.
When the Fn+ESC combo is pressed, FnLock is toggled, which causes the
Media Key functionality to change, making it so that the media keys
either perform their media key function, or function as an F-key by
default. The Fn key can be used the access the alternate function at any
time.
With the current linux kernel, the LED doens't change state if you press
the Fn+ESC key combo. However, the media key functionality *does*
change. This is annoying, since the LED will stay on if it was on during
bootup, and it makes it hard to keep track what the current state of the
FnLock is.
This patch calls an ACPI function, that gets the current media key
state, when the Fn+ESC key combo is pressed. Through testing it was
discovered that this function causes the LED to update correctly to
reflect the current state when this function is called.
The relevant ACPI calls are the following:
\_SB_.PCI0.LPC0.EC0_.HKEY.GMKS: Get media key state, returns 0x603 if the FnLock mode is enabled, and 0x602 if it's disabled.
\_SB_.PCI0.LPC0.EC0_.HKEY.SMKS: Set media key state, sending a 1 will enable FnLock mode, and a 0 will disable it.

Those events occur when a keyboard cover is attached to a ThinkPad
X1 Tablet series device. Typically, they are used to switch from normal
to tablet mode in userspace; e.g., to offer touch keyboard choices when
focus goes to a text box and no keyboard is attached, or to enable
autorotation of the display according to the builtin orientation sensor.
intel-vtbn already recognizes those events. To avoid sending duplicate
events to userspace, they are simply ignored. Thus, this patch only
avoids warnings about unknown and unhandled HKEYs 0x4012 and 0x4013.

All recent ThinkPad BIOS-es support the GSKL method used to query the
keyboard-layout used by the ECFW for the SHIFT + other-key key-press
emulation for special keys such as e.g. the '=', '(' and ')' keys
above the numpad on 15" models.
So just checking for the method is not a good indicator of the
model supporting getting/setting the keyboard_lang.
On models where this is not supported GSKL succeeds, but it returns
METHOD_ERR in the returned integer to indicate that this is not
supported on this model.
Add a check for METHOD_ERR and return -ENODEV if it is set to
avoid registering a non-working keyboard_lang sysfs-attr on models
where this is not supported.

Add support to thinkpad_acpi for returning the status of the palm
sensor.
This patch builds on the work done previously for the input device
implementation (which was not needed). Both lap and palm sensor are using
sysfs and they are combined into the proxsensor block.
Note: On some platforms, because of an issue in the HW implementation,
the palm sensor presence may be incorrectly advertised as always
enabled even if a palm sensor is not present. The palm sensor is
intended for WWAN transmission power control and should be available
and correct on all WWAN enabled systems. It is not recommended to use
this interface for other use cases.

The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node.
This setup relies on a Windows service which reads both accelerometers and
then calculates the angle between the 2 halves to determine laptop / tent /
tablet mode and then reports the calculated mode back to the EC by calling
special ACPI methods on the BOSC0200 node.
The bmc150 iio driver does not support this (it involves double
calculations requiring sqrt and arccos so this really needs to be done
in userspace), as a result of this on the Yoga 11e the thinkpad_acpi
code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting
SW_TABLET_MODE=0 causes GNOME to:
1. Not show the onscreen keyboard when a text-input field is focussed
with the touchscreen.
2. Disable accelerometer based auto display-rotation.
This makes sense when in laptop-mode but not when in tablet-mode. But
since for the Yoga 11e the thinkpad_acpi code always reports
SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode.
Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models
to fix this.
Note there are plans for userspace to support 360 degree hinges style
2-in-1s with 2 accelerometers and figure out the mode by itself, see:

Commit 696c6523ec ("platform/x86: thinkpad_acpi: add mapping for new
hotkeys") added support for a bunch of new hotkeys, but the
clipping/snipping tool hotkey got ignored because there was no good
key-code to map it to.
Recently a new KEY_SELECTIVE_SCREENSHOT keycode was added by commit
3b059da983 ("Input: allocate keycode for "Selective Screenshot" key")
quoting from the commit message:
"New Chrome OS keyboards have a "snip" key that is basically a selective
screenshot (allows a user to select an area of screen to be copied).
Allocate a keycode for it."
Support for this "snip" key seems like it is also a good match for the
clipping/snipping tool hotkey, so map this hotkey to the new
KEY_SELECTIVE_SCREENSHOT key-code.

New Lenovo Thinkpad models, e.g. the X1 Carbon 8th gen and the new T14 gen1
models have 3 new symbols / shortcuts on their F9-F11 keys (and the
thinkpad_acpi driver receives 3 new hkey events for these):
F9: Has a symbol resembling a rectangular speech balloon, the manual says
the hotkey functions shows or hides the notification center
F10: Has a symbol of a telephone horn which has been picked up from the
receiver, the manual says: "Answer incoming calls"
F11: Has a symbol of a telephone horn which is resting on the receiver,
the manual says: "Decline incoming calls"
And these Thinkpad models also send a new 0x1316 hkey events when the
Fn + right Shift key-combo is pressed.
This commit adds support for these 4 new hkey events.

This adds dual fan control for the following models:
P50, P51, P52, P70, P71, P72, P1 gen1, P2 gen2, X1E gen1 and X1E gen2.
Both fans are controlled together as if they were a single fan.
Tested on an X1 Extreme Gen1, an X1 Extreme Gen2, and a P50.
The patch is defensive, it adds only specific supported machines, and falls
back to the old behavior if both fans cannot be controlled.
Background:
I tested the BIOS default behavior on my X1E gen2 and both fans are always
changed together. So rather than adding controls for each fan, this controls
both fans together as the BIOS would do.
This was inspired by a discussion on dual fan support for the thinkfan tool
(see link below). All BIOS IDs are taken from there. The X1E gen2 ID is
verified on my machine.
Thanks to GitHub users voidworker and civic9 for the earlier patches and
BIOS IDs, and to users peter-stoll and sassman for testing the patch on
their machines.

Rather than kmalloc/kzalloc + memcpy, which the programmer needs to
write the size twice (sometimes lead to mistakes), kmemdup improves

In the upcoming change, the binding of audio mute / mic-mute LED
controls will be switched with LED trigger. This patch is the last
piece of preparation: adding the audio mute / mic-mute LED class
devices to thinkpad_acpi driver.
Two devices, platform::mute and platform::micmute, will be added for
controlling the mute LED and mic-mute LED, respectively. The new
prefix "platform" is the suggestion by upstream for indicating the
generic laptop attribute.
Also this selects CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGERS_AUDIO
unconditionally. Strictly speaking, these aren't 100% mandatory, but
leaving these manual selections would lead to a functional regression
easily once after converting from the dynamic symbol binding to the
LEDs trigger in a later patch.

The driver for Silead touchscreen configurations has been renamed
from silead_dmi to touchscreen_dmi since it starts supporting other
touchscreens which require some DMI quirks. At the same release cycle
it gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.
Another bunch of changes is related to Mellanox platform code to allow
user space to communicate with Mellanox for system control and
monitoring purposes. The driver notifies user on hotplug device signal
receiving.
ASUS WMI drivers recognize lid flip action on UX360, and correctly
toggles airplane mode LED. In addition the keyboard backlight toggle
gets support.
ThinkPad ACPI driver enables support for calculator key (on at least P52).
It also has been fixed to support three characters model designators,
which are used for modern laptops. Earlier the battery, marked as BAT1,
on ThinkPad laptops has not been configured properly, which is fixed.
On the opposite the multi-battery configurations now probed correctly.
Dell SMBIOS driver starts working on some Dell servers which do not
support token interface. The regression with backlight detection has
also been fixed. In order to support dock mode on some laptops,
Intel virtual button driver has been fixed. The last but not least
is the fix to Intel HID driver due to changes in Dell systems that
prevented to use power button.
The following is an automated git shortlog grouped by driver:
acer-wmi:
- Silence "unsupported" message a bit
- refactor function has_cap
asus-nb-wmi:
- Add keymap entry for lid flip action on UX360
asus-wireless:

Pull x86 platform driver updates from Andy Shevchenko:
- The driver for Silead touchscreen configurations has been renamed
from silead_dmi to touchscreen_dmi since it starts supporting other
touchscreens which require some DMI quirks
It also gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.
- Another bunch of changes is related to Mellanox platform code to
allow user space to communicate with Mellanox for system control and
monitoring purposes. The driver notifies user on hotplug device
signal receiving.
- ASUS WMI drivers recognize lid flip action on UX360, and correctly
toggles airplane mode LED. In addition the keyboard backlight toggle
gets support.
- ThinkPad ACPI driver enables support for calculator key (on at least
P52). It also has been fixed to support three characters model
designators, which are used for modern laptops. Earlier the battery,
marked as BAT1, on ThinkPad laptops has not been configured properly,
which is fixed. On the opposite the multi-battery configurations now
probed correctly.
- Dell SMBIOS driver starts working on some Dell servers which do not
support token interface. The regression with backlight detection has
also been fixed. In order to support dock mode on some laptops, Intel
virtual button driver has been fixed. The last but not least is the
fix to Intel HID driver due to changes in Dell systems that prevented
to use power button.

Some Thinkpads have a single battery, but expose it as BAT1. Use the quirks

Without this, the battery name would resolve to the non-existent secondary

Because the P50 doesn't report the version of its EC controller,

This patch prevents the thinkpad_acpi driver from warning about 2 event
codes returned for keyboard palm-detection. No behavioral changes,
other than suppressing the warning in the kernel log. The events are
still forwarded via acpi-netlink channels.
We could, optionally, decide to forward the event through a
input-switch on the tpacpi input device. However, so far no suitable

leave it an acpi event for now.
Note that the event-codes are named based on empirical studies. On the
ThinkPad X1 5th Gen the sensor can be found underneath the arrow key.

For this cycle we have quite an update for the Dell SMBIOS driver
including WMI work to provide an interface for SMBIOS tokens via sysfs
and WMI support for 2017+ Dell laptop models. SMM dispatcher code is
split into a separate driver followed by a new WMI dispatcher.
The latter provides a character device interface to user space.
The pull request contains a merge of immutable branch from Wolfram Sang
in order to apply a dependent fix to the Intel CherryTrail Battery
Management driver.
Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0
support is added for Intel Skylake.
Peaq WMI hotkeys driver gets its own maintainer and white list of
supported models.
Silead DMI is expanded to support few additional platforms.
Tablet mode via GMMS ACPI method is added to support some ThinkPad
tablets.

Many thinkpad laptops and convertibles provide the GMMS method to
resolve how far the laptop has been opened and whether it has been
converted into tablet mode. This allows reporting a more precise tablet
mode state to userspace.
The current implementation only reports a summarized tablet mode state
which is triggered as soon as the input devices become unusable as they
are folded away from the display.
This will work on all models where the CMMD method was used previously and
it may also work in other cases.
Thanks to Peter Zhang of Lenovo for providing information on how to use the
GMMS method to query the tablet mode.

Use hwmon_device_register_with_groups instead of deprecated
hwmon_device_register and fix a dmesg warning.
This patch however changes the userspace API.
hwmon_device_register_with_groups takes `hwmon' name as an argument and
creates a name file in the `hwmon' device, not in the `platform_device'.
This allows us to remove custom `name' device attribute, but in order to
make lm-sensors happy we also have to move fans and thermal attributes
to the `hwmon' device.
Even though this patch changes userspace API, it's still compatible with
the lm-sensors. Starting with lm-sensors 3.0 (circa 2007), it looks at
both hwmon and the backing device for the name and other attributes.

We are trying to get rid of DRIVER_ATTR(), and the thinkpad_acpi
driver's attributes can be trivially changed to use DRIVER_ATTR_RO() and
DRIVER_ATTR_RW().

As per discussion [1] there are only few users of module_param_call() in
kernel which prevent to read module parameters back.
It thinkpad_acpi driver there is even no method do so. Thus, for now,
add just a comment to explain why 0 is used as permissions in
module_param_call().

There is no point to keep string literal split. It even makes slightly
harder to maintain and debug.
Join string literals back to be oneliners.
While here, print negative error without changing a sign as it is a
common pattern in the kernel.
Other than above there were no functional changes intended.

The T470, X270 emits new hkey events in the 0x1311 - 0x1315 range.
According to the user manual they should launch a user selected
favorite application (star icon, 0x1311), snipping tool (0x1312,
currently ignored), enable/disable bluetooth (0x1314) and open they
keyboard settings (0x1315).
The third nibble (0xf00) is used to differentiate between the original
hotkeys, the adaptive keyboard codes and the new, additional ones.

Currently when dispatching hotkeys we check if the scancode is in
the range of 0 and TPACPI_HOTKEY_MAP_LEN, although the bottom 20
entries in the hotkey keymap are already adaptive keycodes.
Therefore we introduce a TP_ACPI_HOTKEYSCAN_ADAPTIVE_START and
ensure that we are in the range 0 and ADAPTIVE_START for the generic
keycode case.

Make thinkpad_acpi call led_classdev_notify_brightness_hw_changed on the
kbd_led led_classdev registered by thinkpad_acpi when the kbd backlight
brightness is changed through the hotkey.
This will allow userspace to monitor (poll) for brightness changes on
these LEDs caused by the hotkey.

Now a days the LED core can take care of executing brightness_set from
a workqueue if it needs to sleep, make use of this and remove a bunch
of DIY code for this.
Since this commit removes the workqueue usage for LEDs, the
led_sysfs_blink_set callback may now also sleep, this is fine.

There is no need to set the led_classdev's brightness value from
its set_brightness callback, this is taken care of by the led-core and
thinkpad_acpi really should not be mucking with it.
Note that kbdlight_set_level_and_update() is still used by the old
thinpad_acpi specific sysfs interface for the led, so we cannot
remove it.

linux-next reported in_tablet_mode and type may be used uninitialized
after:
b318002838 ("platform/x86: thinkpad_acpi: Move tablet detection into separate function")
This turns out to be a false positive as the pr_info call cannot be
reached if tp_features.hotkey_tablet (global scope) is 0, and
in_tablet_mode and type are assigned in both places
tp_features.hotkey_tablet is assigned.
Regardless, to make it explicit and avoid further reports, initialize
in_tablet_mode to 0 and type to NULL.

Recently we met an issue on lots of Lenovo thinkpad laptops (those
laptops are not released to market yet), the issue is that the
thinkpad_acpi.ko can't be automatically loaded as before.
Through debugging, we found the HKEY_HID is LEN0268 instead of
LEN0068 on those machines, and the MHKV is 0x200 instead of
0x100. So adding the new ID into the driver.
