2025-10-14HID: nintendo: Wait longer for initial probeVicki Pfau
Some third-party controllers, such as the PB Tails CHOC, won't always respond quickly on startup. Since this packet is needed for probe, and only once during probe, let's just wait an extra second, which makes connecting consistent.

2025-10-14HID: logitech-hidpp: Do not assume FAP in hidpp_send_message_sync()Mavroudis Chatzilazaridis
Currently, hidpp_send_message_sync() retries sending the message when the device returns a busy error code, specifically HIDPP20_ERROR_BUSY, which has a different meaning under RAP. This ends up being a problem because this function is used for both FAP and RAP messages. This issue is not noticeable on older receivers with unreachable devices since they return HIDPP_ERROR_RESOURCE_ERROR (0x09), which is not equal to HIDPP20_ERROR_BUSY (0x08). However, newer receivers return HIDPP_ERROR_UNKNOWN_DEVICE (0x08) which happens to equal to HIDPP20_ERROR_BUSY, causing unnecessary retries when the device is not actually busy. This is resolved by checking if the error response is FAP or RAP and picking the respective ERROR_BUSY code.

2025-10-14HID: logitech-hidpp: Silence protocol errors on newer lightspeed receiversMavroudis Chatzilazaridis
When logitech-hidpp tries to communicate with an unreachable device paired to a 046d:c547 lightspeed receiver, the following message is printed to the console: hidpp_root_get_protocol_version: received protocol error 0x08 This occurs because this receiver returns 0x08 (HIDPP_ERROR_UNKNOWN_DEVICE) when a device is unreachable, compared to 0x09 (HIDPP_ERROR_RESOURCE_ERROR) that the older receivers return. This patch silences this harmless error by treating HIDPP_ERROR_UNKNOWN_DEVICE the same as HIDPP_ERROR_RESOURCE_ERROR in hidpp_root_get_protocol_version(). There are other checks for HIDPP_ERROR_RESOURCE_ERROR found in battery-related functions, however this receiver does not trigger them when the device is disconnected.

2025-10-14HID: logitech-dj: Add support for a new lightspeed receiver iterationMavroudis Chatzilazaridis
This lightspeed receiver uses 13 byte mouse reports without an ID. There are 5 additional vendor defined bytes appended to the report. The workaround for such cases has been adjusted to handle these larger reports. The keyboard reports have a distinct layout with differing minimums and maximums. Additionally, the LED reports now require a report ID of 1. New keyboard and mouse descriptors have been added to reflect these changes. The devices attached to this receiver now report the status of their battery in wireless mode, libratbag communicates with them and they can be configured with Piper.

Add hw_brightness_changed support for the G510 keyboard, so that e.g. GNOME will show an OSD notification when toggling the backlight on/off with the button the keyboard. Note that it is not possible to turn the backlight back on by writing /sys/class/leds/.../brightness it can only be turned on by pressing the button on the keyboard.

edge detection The original implementation used level detection for the first interrupt after device reset to avoid potential interrupt line noise and missed interrupts during the initialization phase. However, this approach introduced unintended side effects when tested with certain touch panels, including: - Delayed hardware interrupt response - Multiple spurious interrupt triggers Switching back to edge detection for the first interrupt resolves these issues while maintaining reliable interrupt handling. Extensive testing across multiple platforms with touch panels from various vendors confirms this change introduces no regressions.

2025-10-01Drivers: hv: Add CONFIG_HYPERV_VMBUS optionMukesh Rathor
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.

The handling for variable-length ioctl commands in hidraw_ioctl() is rather complex and the check for the data direction is incomplete. Simplify this code by factoring out the various ioctls grouped by dir and size, and using a switch() statement with the size masked out, to ensure the rest of the command is correctly matched.

2025-09-17HID: playstation: Support DualSense audio jack event reportingCristian Ciocaltea
The DualSense controller complies with v1.0 of the USB Audio Class spec (UAC1), hence it cannot advertise any jack detection capability. However, this feature can be implemented in the generic USB audio driver via quirks, i.e. by configuring an input handler to receive hotplug events from the HID driver. When operating in USB mode, register a dedicated input device for the audio jack and use it to report all headphone and headset mic insert events.

2025-09-17HID: playstation: Support DualSense audio jack hotplug detectionCristian Ciocaltea
The default audio output path on DualSense controller hardware is set to headphones, regardless of whether they are actually inserted or not. Detect when the plugged state of the 3.5mm audio jack changes and toggle audio output between headphones and internal speaker, as required. The latter is achieved by essentially routing the right channel of the audio source to the mono speaker. Additionally, adjust the speaker volume since its default level is too low and, therefore, cannot generate any audible sound. It's worth noting the audio functionality is currently not supported for Bluetooth, hence it's limited to USB connectivity.

The 'status' member of struct dualsense_input_report is currently used to store just the battery data, despite the fact that hardware is capable to report two extra bytes of status information. In preparation to make use of some of the additional data, redefine the field type as a 3-byte array. Moreover, to preserve consistency with the related DS_STATUS[0..2]_* registers in datasheet, rename DS_STATUS_* bitfield macros accordingly.

2025-09-16HID: i2c-hid: Resolve touchpad issues on Dell systems during S4Mario Limonciello (AMD)
Dell systems utilize an EC-based touchpad emulation when the ACPI touchpad _DSM is not invoked. This emulation acts as a secondary master on the I2C bus, designed for scenarios where the I2C touchpad driver is absent, such as in BIOS menus. Typically, loading the i2c-hid module triggers the _DSM at initialization, disabling the EC-based emulation. However, if the i2c-hid module is missing from the boot kernel used for hibernation snapshot restoration, the _DSM remains uncalled, resulting in dual masters on the I2C bus and subsequent arbitration errors. This issue arises when i2c-hid resides in the rootfs instead of the kernel or initramfs. To address this, switch from using the SYSTEM_SLEEP_PM_OPS() macro to dedicated callbacks, introducing a specific callback for restoring the S4 image. This callback ensures the _DSM is invoked.
