| * HID: input: Fix Apple Magic Trackpad 1 Bluetooth disconnectNimish Gåtam2023-08-141-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When connecting the Trackpad 1 via any bluetooth adapter, the device disconnects whenever the battery level is queried. It reconnects again after a few seconds, but it's an incredibly jarring experience since it will just cut out in the middle of mouse operations. This patch ignores querying the battery and avoids disconnects. This bug is reported here: - https://bugzilla.kernel.org/show_bug.cgi?id=204589 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834085 It looks like a similar approach (disabling battery checking) was also suggested for the Apple Magic Mouse before a custom driver was created: https://bugzilla.kernel.org/show_bug.cgi?id=103631 Signed-off-by: Nimish Gåtam <nimishg@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* | HID: input: Support devices sending Eraser without InvertIllia Ostapyshyn2023-08-141-2/+16
|/ | | | | | | | | | | | | | | | | | | | | | | Some digitizers (notably XP-Pen Artist 24) do not report the Invert usage when erasing. This causes the device to be permanently stuck with the BTN_TOOL_RUBBER tool after sending Eraser, as Invert is the only usage that can release the tool. In this state, Touch and Inrange are no longer reported to userspace, rendering the pen unusable. Prior to commit 87562fcd1342 ("HID: input: remove the need for HID_QUIRK_INVERT"), BTN_TOOL_RUBBER was never set and Eraser events were simply translated into BTN_TOUCH without causing an inconsistent state. Introduce HID_QUIRK_NOINVERT for such digitizers and detect them during hidinput_configure_usage(). This quirk causes the tool to be released as soon as Eraser is reported as not set. Set BTN_TOOL_RUBBER in input->keybit when mapping Eraser.

* HID: input: fix mapping for camera access keysDmitry Torokhov2023-07-091-3/+4
| | | | | | | | | | | | | | | | | | Commit 9f4211bf7f81 ("HID: add mapping for camera access keys") added mapping for the camera access keys, but unfortunately used wrong usage codes for them. HUTRR72[1] specifies that camera access controls use 0x76, 0x077 and 0x78 usages in the consumer control page. Previously mapped 0xd5, 0xd6 and 0xd7 usages are actually defined in HUTRR64[2] as game recording controls.

Turns out that the uclogic driver has a timer to release the in range bit, effectively making hid-input ignoring all in range information after the very first one. Fix that by having a more rationale approach which consists in forwarding every event and let the input stack filter out the duplicates.

Furthermore, it didn't make sense to use a global per struct hid_device quirk for something dynamic as the current state. Store the current tool information in the report itself, and re-order the processing of the fields to enforce having all the tablet "state" fields before getting to In Range and other input fields. This way, we now have all the information whether a tool is present or not while processing In Range. This new behavior enforces that only one tool gets forwarded to userspace at the same time, and that if either eraser or invert is set, we enforce BTN_TOOL_RUBBER. Note that the release of the previous tool now happens in its own EV_SYN report so userspace doesn't get confused by having 2 tools.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This and HID_DG_STYLUS are pretty much the same thing so add suffix for HID_DG_PEN too. This makes the input device name look better. While doing this, remove the suffix override from hid-multitouch, as it is now handled by hid-input. Also, the suffix override done by hid-multitouch was wrong, as it mapped HID_DG_PEN => "Stylus" and HID_DG_STYLUS => "Pen".

* HID: input: set usage type to key on keycode remapThomas Weißschuh2021-11-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a scancode is manually remapped that previously was not handled as key, then the old usage type was incorrectly reused. This caused issues on a "04b3:301b IBM Corp. SK-8815 Keyboard" which has marked some of its keys with an invalid HID usage. These invalid usage keys are being ignored since support for USB programmable buttons was added. The scancodes are however remapped explicitly by the systemd hwdb to the keycodes that are printed on the physical buttons. During this mapping step the existing usage is retrieved which will be found with a default type of 0 (EV_SYN) instead of EV_KEY. The events with the correct code but EV_SYN type are not forwarded to userspace. This also leads to a kernel oops when trying to print the report descriptor via debugfs. hid_resolv_event() tries to resolve a EV_SYN event with an EV_KEY code which leads to an out-of-bounds access in the EV_SYN names array.

| | | | | | | | | | | | | | | | | | | The power supply states of discharging, charging, full, etc, represent state of charging, not the capacity level of the battery (for which we have a separate property). Current HID usage tables to not allow for expressing charging state of the batteries found in generic styli, so we should simply assume that the battery is discharging even if current capacity is at 100% when battery strength reporting is done via HID interface. In fact, we were doing just that before commit 581c4484769e. This change helps UIs to not mis-represent fully charged batteries in styli as being charging/topping-off.
