If CONFIG_HID_HYPERV is built-in (=y) while CONFIG_KUNIT is built as a module
(=m), the linker fails to resolve kunit_mem_assert_format when creating
vmlinux.
Fix the dependencies in Kconfig.

Adds configuration HID driver for the MSI Claw series of handheld PC's.
In this initial patch add the initial driver outline and attributes for
changing the gamepad mode, M-key behavior, and add a WO reset function.
Sending the SWITCH_MODE and RESET commands causes a USB disconnect in
the device. The completion will therefore never get hit and would trigger
an -EIO. To avoid showing the user an error for every write to these
attrs a bypass for the completion handling is introduced when timeout ==
0.
The initial version of this patch was written by Denis Benato, which
contained the initial reverse-engineering and implementation for the
gamepad mode switching. This work was later expanded by Zhouwang Huang
to include more gamepad modes. Finally, I refactored the drivers data
in/out flow and overall format to conform to kernel driver best
practices and style guides. Claude was used as an initial reviewer of
this patch.

The tap-to-mute button of the HyperX QuadCast 2 (03f0:07b4) is handled
entirely in the device firmware. The firmware gates the audio internally
but never sends the Telephony "Phone Mute" usage (0x2f) that its own report
descriptor advertises, and it does not touch the UAC feature unit either.
Consequently neither an evdev key event nor an ALSA mixer change is ever
generated, and userspace has no way to learn that the microphone was muted:
desktops keep showing the microphone as live, and conferencing applications
keep displaying an unmuted microphone while transmitting silence.
The mute state is reported through a vendor-defined collection instead:
06 c0 ff Usage Page (Vendor-Defined 0xFFC0)
a1 01 Collection (Application)
06 c1 ff Usage Page (Vendor-Defined 0xFFC1)
85 77 Report ID (0x77)
09 f0 Usage (0xF0)
75 08 95 3f Report Size (8), Report Count (63)
81 02 Input (Data,Var,Abs)
Pressing the button emits a 64-byte report on that collection:
77 06 00 00 ... microphone unmuted
77 06 01 00 ... microphone muted
where byte 1 identifies the mute event and byte 2 carries the resulting
state. As the payload is an opaque vendor blob carrying no HID usages,
hid-input cannot map it and a hwdb entry cannot express it either.
Add a driver that decodes the report and emits KEY_MICMUTE, which makes the
button behave like any other microphone mute key.
Note that the device reports the resulting absolute state, whereas
KEY_MICMUTE is a momentary key that userspace acts on as a toggle, so the
driver emits one keypress per state change.
Tested on a HyperX QuadCast 2 (03f0:07b4).

Add KUnit coverage for Hyper-V synthetic HID initial device-info parsing.
The tests cover zero bLength, a valid descriptor plus report descriptor,
and a malformed report descriptor length that exceeds the received
message.
The same-translation-unit test uses a KUnit-only ACK bypass so parser
coverage does not require a live VMBus channel.

to_usb_interface() can only be used on a hid_device whose parent is really
USB; uhid can create devices that identify as being on BUS_USB, but don't
actually have a USB parent.
Fix the use of to_usb_interface() without a hid_is_usb() check.
Add a dependency on USB_HID for hid_is_usb(), as other HID drivers do; the
alternative would be to provide a simple stub implementation on !USB_HID
builds.
I have verified that it is currently possible to trigger a kernel splat due
to this bug in an ASAN build, and that this commit fixes the issue.

Drive kone_keep_values_up_to_date() with a crafted switch-profile event;
an out-of-range value reads past profiles[] (KASAN slab-out-of-bounds on
an unpatched tree). A benign control with an in-range value exercises the
same path. The test object is sized to end at profiles[] so the over-read
lands in the KASAN redzone.

- suport for OneXPlayer (Derek J. Clark)
|
|
Adds support for the second generation of RGB Control for OneXPlayer
devices. The interface mirrors the first generation, with some
differences to how messages are formatted.
Some devices have both a GEN1 MCU for RGB control and a GEN2 MCU for
button mapping. To avoid conflicts, quirk these devices to skip RGB
setup for the GEN2_USAGE_PAGE.

Adds OneXPlayer HID configuration driver. In this initial driver patch,
add the RGB interface for the first generation of HID based RGB control.
This interface provides the following attributes:
- brightness: provided by the LED core, this works in a fairly unique
way on this device. The hardware accepts 5 brightness values (0-4),
which affects the brightness of the multicolor and animated effects
built into the MCU firmware. For monocolor settings, the device
expects the hardware brightness value to be pushed to maximum, then we
apply brightness adjustments mathematically based on % (0-100). This
leads to some odd conversion as we need the brightness slider to reach
the full range, but it has no affect when incrementing between the
division points for other effects.
- multi-intensity: provided by the LED core for red, green, and blue.
- effect: Allows the MCU to set 19 individual effects.
- effect_index: Lists the 19 valid effect names for the interface.
- enabled: Allows the MCU to toggle the RGB interface on/off.
- enabled_index: Lists the valid states for enabled.
- speed: Allows the MCU to set the animation rate for the various
effects.
- speed_range: Lists the valid range of speed (0-9).
The MCU also has a few odd quirks that make sending multiple synchronous
events challenging. It will essentially freeze if it receives another
message before it has finished processing the last command. It also will
not reply if you wait on it using a completion. To get around this, we
do a 200ms sleep inside a work queue thread and debounce all but the most
recent message using a 50ms mod_delayed_work. This will cache the last
write, queue the work, then return so userspace can release its write
thread. The work queue is only used for brightness/multi-intensity as
that is the path likely to receive rapid successive writes.

The Rakk Dasig X gaming mouse has a faulty HID report descriptor that
declares USAGE_MAXIMUM=3 (buttons 1-3) while actually sending 5 button
bits (REPORT_COUNT=5). This causes the kernel to ignore side buttons
(buttons 4 and 5).
Fix by patching the descriptor to set USAGE_MAXIMUM=5 in the
report_fixup callback.
The mouse uses Telink vendor ID 0x248a with three product IDs for USB
direct (0xfb01), wireless dongle (0xfa02), and Bluetooth (0x8266)
connection modes. All three variants have the same bug at byte offset 17.

Device drivers generally should not select other subsystems like this, as

Change these two and the older hid-lenovo driver to behave the same way as all
other HID drivers and use 'depends on LEDS_CLASS' or 'depends on LEDS_CLASS_MULTICOLOR'
instead, which itself has NEW_LEDS and LEDS_CLASS as dependencies.

Adds initial framework for a new HID driver, hid-lenovo-go, along with
attributes that report the firmware and hardware version for each
component of the HID device, of which there are 4 parts: The MCU, the
transmission dongle, the left "handle" controller half, and the right
"handle" controller half. Each of these devices are provided an attribute
group to contain its device specific attributes. Additionally, the touchpad
device attributes are logically separated from the other components in
another attribute group.
This driver primarily provides access to the configurable settings of the
Lenovo Legion Go and Lenovo Legion Go 2 controllers running the latest
firmware. As previously noted, the Legion Go controllers recently had a
firmware update[1] which switched from the original "SepentiaUSB" protocol
to a brand new protocol for the Go 2, primarily to ensure backwards and
forwards compatibility between the Go and Go 2 devices. As part of that
update the PIDs for the controllers were changed, so there is no risk of
this driver attaching to controller firmware that it doesn't support.

New model in the ELECOM HUGE trackball line that has 8 buttons but the
report descriptor specifies only 5. The HUGE Plus supports connecting via
Bluetooth, 2.4GHz wireless USB dongle, and directly via a USB-C cable.
Each connection type reports a different device id, 01AA for cable,
01AB for USB dongle, and 01AC for Bluetooth.
This patch adds these device IDs and applies the fixups similar to the
other ELECOM devices to get all 8 buttons working for all 3 connection
types.

At present VMBus driver is hinged off of CONFIG_HYPERV which entails
lot of builtin code and encompasses too much. It's not always clear
what depends on builtin hv code and what depends on VMBus. Setting
CONFIG_HYPERV as a module and fudging the Makefile to switch to builtin
adds even more confusion. VMBus is an independent module and should have
its own config option. Also, there are scenarios like baremetal dom0/root
where support is built in with CONFIG_HYPERV but without VMBus. Lastly,
there are more features coming down that use CONFIG_HYPERV and add more
dependencies on it.
So, create a fine grained HYPERV_VMBUS option and update Kconfigs for
dependency on VMBus.

- Implement haptic touchpad support (Angela Czubak and Jonathan Denose)
|
|
Define a new structure that contains simple haptic device configuration
as well as current state.
Add functions that recognize auto trigger and manual trigger reports
as well as save their addresses.
Verify that the pressure unit is either grams or newtons.
Mark the input device as a haptic touchpad if the unit is correct and
the reports are found.

Commit 84c9d2a968c82 ("HID: lenovo: Support for ThinkPad-X12-TAB-1/2 Kbd
Fn keys") added a dependency on ACPI's platform_profile. This should not
be done for generic USB devices as this prevents using the devices on
non ACPI devices like Apple silicon Macs and other non-ACPI arm64
systems. An attempt to allow using platform_profile on non-ACPI systems
was rejected in [1] and instead platform_profile was made to fail during
init in commit dd133162c9cf ("ACPI: platform_profile: Avoid initializing
on non-ACPI platforms").
So remove the broken dependency and instead let's user space handle this
keycode by sending the new KEY_PERFORMANCE. Stable backport depends on
commit 89c5214639294 ("Input: add keycode for performance mode key").

The Apple Touch Bar is only present on x86 MacBook Pros. Hence add a
dependency on X86, to prevent asking the user about this driver when
configuring a kernel for a different architecture.

From: Tomasz Pakuła <tomasz.pakula.oficjalny@gmail.com>
This patch series is focused on improving the compatibility and usability of the
hid-pidff force feedback driver. Last patch introduces a new, universal driver
for PID devices that need some special handling like report fixups, remapping the
button range, managing new pidff quirks and setting desirable fuzz/flat values.
This work has been done in the span of the past months with the help of the great
Linux simracing community, with a little input from sim flight fans from FFBeast.
No changes interfere with compliant and currently working PID devices.
"Generic" codepath was tested as well with Moza and Simxperience AccuForce v2.
I'm not married to the name. It's what we used previously, but if "universal" is
confusing (pidff is already the generic driver), we can come up with something
better like "hid-quirky-pidff" :)
With v8 and tiny finx in v9, all the outstanding issues were resolved,
additional pidff issues were fixed and hid-pidff defines moved to a dedicated
header file. This patch series could be considered done bar any comments and
requests from input maintainers.
I could save more then a dozen lines of code by changing simple if statements
to only occupy on line instead of two in there's a need for that.

- conversion of hid-lg-g15 to standard multicolor LED API (Kate Hsuan)
|
|
- support for Apple Touch Bars (Kerem Karabay, Aditya Garg)
|

The test bot found an issue with building hid-lg-g15.
All errors (new ones prefixed by >>):
powerpc-linux-ld: drivers/hid/hid-lg-g15.o: in function `lg_g510_kbd_led_write':
>> drivers/hid/hid-lg-g15.c:241:(.text+0x768): undefined reference to `led_mc_calc_color_components'

>> drivers/hid/hid-lg-g15.c:686:(.text+0xa9c): undefined reference to `devm_led_classdev_multicolor_register_ext'
Since multicolor LED APIs manage the keyboard backlight settings of
hid-lg-g15, the LEDS_CLASS_MULTICOLOR dependency was added to
HID_LOGITECH.

using the touchbar
On Windows, if there is no input by the user for 60 sec, the Touch Bar dims
automatically, and after further 15 sec, it turns off. On receiving input,
the Touch Bar resets the timer and goes back to full brightness. This patch
implements the same functionality.

The Touch Bars found on x86 Macs support two USB configurations: one
where the device presents itself as a HID keyboard and can display
predefined sets of keys, and one where the operating system has full
control over what is displayed. This commit adds a driver for the
display functionality of the first configuration.
Note that currently only T2 Macs are supported.
This driver is based on previous work done by Ronald Tschalär
<ronald@innovation.ch>.

Newer model R3* Topre Realforce keyboards share an issue with their older
R2 cousins where a report descriptor fixup is needed in order for n-key
rollover to work correctly, otherwise only 6-key rollover is available.
This patch adds some new hardware IDs for the R3S 87-key keyboard and
makes amendments to the existing hid-topre driver in order to change the
correct byte in the new model.
