2023-02-06HID: amd_sfh: if no sensors are enabled, clean upMario Limonciello2-2/+12
It was reported that commit b300667b33b2 ("HID: amd_sfh: Disable the interrupt for all command") had caused increased resume time on HP Envy x360. Before this commit 3 sensors were reported, but they were not actually functional. After this commit the sensors are no longer reported, but also the resume time increased. To avoid this problem explicitly look for the number of disabled sensors. If all the sensors are disabled, clean everything up.

2023-02-06HID: logitech: Disable hi-res scrolling on USBBastien Nocera1-1/+2
On some Logitech mice, such as the G903, and possibly the G403, the HID events are generated on a different interface to the HID++ one. If we enable hi-res through the HID++ interface, the HID interface wouldn't know anything about it, and handle the events as if they were regular scroll events, making the mouse unusable. Disable hi-res scrolling on those devices until we implement scroll events through HID++.

2023-02-06HID: hid-steam: Add Steam Deck supportVicki Pfau3-28/+306
Add preliminary support for the Steam Deck's controller interface. Currently, this only supports the controller inputs and toggling lizard mode (Valve's name for a hardware kb/m emulation mode). It does not support any of the advanced features, such as the motion sensors or force-feedback. The Steam Deck also includes a heartbeat for lizard mode that switches it back on if no reports have been received within a few milliseconds. The official Steam client handles this by sending a handful of configuration reports every few ms, so we copy this behavior by sending configuration reports to disable the mouse and reset the digital mappings every 5ms. As this isn't needed for the older Steam Controller, this is only done on the Steam Deck.

2023-02-03platform/surface: aggregator: Rename top-level request functions to avoid ↵Maximilian Luz2-6/+6
ambiguities We currently have a struct ssam_request_sync and a function ssam_request_sync(). While this is valid C, there are some downsides to it. One of these is that current Sphinx versions (>= 3.0) cannot disambiguate between the two (see disucssion and pull request linked below). It instead emits a "WARNING: Duplicate C declaration" and links for the struct and function in the resulting documentation link to the same entry (i.e. both to either function or struct documentation) instead of their respective own entries. While we could just ignore that and wait for a fix, there's also a point to be made that the current naming can be somewhat confusing when searching (e.g. via grep) or trying to understand the levels of abstraction at play: We currently have struct ssam_request_sync and associated functions ssam_request_sync_[alloc|free|init|wait|...]() operating on this struct. However, function ssam_request_sync() is one abstraction level above this. Similarly, ssam_request_sync_with_buffer() is not a function operating on struct ssam_request_sync, but rather a sibling to ssam_request_sync(), both using the struct under the hood. Therefore, rename the top level request functions: ssam_request_sync() -> ssam_request_do_sync() ssam_request_sync_with_buffer() -> ssam_request_do_sync_with_buffer() ssam_request_sync_onstack() -> ssam_request_do_sync_onstack() Link: https://lore.kernel.org/all/085e0ada65c11da9303d07e70c510dc45f21315b.1656756450.git.mchehab@kernel.org/ Link: https://github.com/sphinx-doc/sphinx/pull/8313 Signed-off-by: Maximilian Luz <luzmaximilian@gmail.com> Link: https://lore.kernel.org/r/20221220175608.1436273-2-luzmaximilian@gmail.com Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

Similar to the target category (TC), the target ID (TID) can be one value out of a small number of choices, given in enum ssam_ssh_tid. In the device ID macros, SSAM_SDEV() and SSAM_VDEV() we already use text expansion to, both, remove some textual clutter for the target category values and enforce that the value belongs to the known set. Now that we know the names for the target IDs, use the same trick for them as well. Also rename the SSAM_ANY_x macros to SSAM_SSH_x_ANY to better fit in.

2023-01-19HID: bpf: rework how programs are attached and stored in the kernelBenjamin Tissoires2-67/+77
Previously, HID-BPF was relying on a bpf tracing program to be notified when a program was released from userspace. This is error prone, as LLVM sometimes inline the function and sometimes not. So instead of messing up with the bpf prog ref count, we can use the bpf_link concept which actually matches exactly what we want: - a bpf_link represents the fact that a given program is attached to a given HID device - as long as the bpf_link has fd opened (either by the userspace program still being around or by pinning the bpf object in the bpffs), the program stays attached to the HID device - once every user has closed the fd, we get called by hid_bpf_link_release() that we no longer have any users, and we can disconnect the program to the device in 2 passes: first atomically clear the bit saying that the link is active, and then calling release_work in a scheduled work item. This solves entirely the problems of BPF tracing not showing up and is definitely cleaner.

2023-01-18HID: uclogic: Handle wireless device reconnectionJosé Expósito5-0/+271
UGEEv2 tablets with battery can be connected using a USB cable or a USB Bluetooth dongle. When the Bluetooth dongle is used, the connection to that tablet can be lost because the tablet is out of the range of the receiver or because it was switched off using the switch placed in the back of the tablet's frame. After losing connection, the tablet is able to reconnect automatically and its firmware sends a special packet indicating that the device was reconnected. In response to this packet, the tablet needs to receive the same array of magic data it expects on probe to enable its interfaces. This patch implements a generic mechanism to hook raw events and schedule a work to perform any custom action.

2023-01-18HID: uclogic: Add battery quirkJosé Expósito2-0/+6
Some UGEE v2 tablets have a wireless version with an internal battery and their firmware is able to report their battery level. However, there was not found a field on their descriptor indicating whether the tablet has battery or not, making it mandatory to classify such devices through the UCLOGIC_BATTERY_QUIRK quirk.

2023-01-18HID: uclogic: Add frame type quirkJosé Expósito3-19/+29
The report descriptor used to get information about UGEE v2 devices is incorrect in the XP-PEN Deco Pro SW. It indicates that the device frame is of type UCLOGIC_PARAMS_FRAME_BUTTONS but the device has a frame of type UCLOGIC_PARAMS_FRAME_MOUSE. Here is the original report descriptor: 0x0e 0x03 0xc8 0xb3 0x34 0x65 0x08 0x00 0xff 0x1f 0xd8 0x13 0x00 0x00 ^ This byte should be 2 Add a quirk to be able to fix the reported frame type.

2023-01-18HID: i2c-hid: switch to standard debugging APIsThomas Weißschuh1-10/+1
Instead of implementing a custom form of dynamic debugging we can use the standard debugging APIs. If the kernel is built with CONFIG_DYNAMIC_DEBUG this will be more discoverable and featureful. Also the previous module parameter "debug" is read-only so it can't actually be enabled. Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2023-01-17Drivers: hv: Make remove callback of hyperv driver void returnedDawei Li1-3/+1
Since commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned, it doesn't make much sense for any bus based driver implementing remove callbalk to return non-void to its caller. As such, change the remove function for Hyper-V VMBus based drivers to return void.

Add a check for empty report_list in bigben_probe(). The missing check causes a type confusion when issuing a list_entry() on an empty report_list. The problem is caused by the assumption that the device must have valid report_list. While this will be true for all normal HID devices, a suitably malicious device can violate the assumption.
