commit 87562fcd1342 ("HID: input: remove the need for HID_QUIRK_INVERT") made the assumption that it was the only one handling tablets and thus kept an internal state regarding the tool. 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.

2022-03-01HID: input: remove the need for HID_QUIRK_INVERTBenjamin Tissoires1-8/+90
HID_QUIRK_INVERT is kind of complex to deal with and was bogus. 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. These changes are tested in the following hid-tools regression tests: https://gitlab.freedesktop.org/libevdev/hid-tools/-/merge_requests/127 Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Reviewed-by: Ping Cheng <ping.cheng@wacom.com> Acked-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2022-03-01HID: input: enforce Invert usage to be processed before InRangeBenjamin Tissoires1-2/+32
When a device exposes both Invert and InRange, Invert must be processed before InRange. If we keep the order of the device and we process them out of order, InRange will first set BTN_TOOL_PEN, and then Invert will set BTN_TOOL_RUBBER. Userspace knows how to deal with that situation, but fixing it in the kernel is now easier.

2021-11-19HID: input: set usage type to key on keycode remapThomas Weißschuh1-0/+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.

2021-06-24HID: input: Add support for Programmable ButtonsThomas Weißschuh1-0/+22
Map them to KEY_MACRO# event codes. These buttons are defined by HID as follows: "The user defines the function of these buttons to control software applications or GUI objects." This matches the semantics of the KEY_MACRO# input event codes that Linux supports. Also add support for HID "Named Array" collections. Also add hid-debug support for KEY_MACRO#.

2021-06-14HID: hid-input: add Surface Go battery quirkZoltan Tamas Vajda1-0/+2
The Elantech touchscreen/digitizer in the Surface Go mistakenly reports having a battery. This results in a low battery message every time you try to use the pen. This patch adds a quirk to ignore the non-existent battery and gets rid of the false low battery messages.

2021-05-05HID: hid-input: add mapping for emoji picker keyDmitry Torokhov1-0/+3
HUTRR101 added a new usage code for a key that is supposed to invoke and dismiss an emoji picker widget to assist users to locate and enter emojis. This patch adds a new key definition KEY_EMOJI_PICKER and maps 0x0c/0x0d9 usage code to this new keycode. Additionally hid-debug is adjusted to recognize this new usage code as well.

2021-04-07HID: input: map battery capacity (00850065)John Chen1-6/+16
This is the capacity in percentage, relative to design capacity. Specifically, it is present in Apple Magic Mouse 2. In contrast, usage 00850064 is also the capacity in percentage, but is relative to full capacity. It is not mapped here because I don't have such device.

2021-02-02HID: hid-input: avoid splitting keyboard, system and consumer controlsDmitry Torokhov1-0/+10
A typical USB keyboard usually splits its keys into several reports: - one for the basic alphanumeric keys, modifier keys, F<n> keys, six pack keys and keypad. This report's application is normally listed as GenericDesktop.Keyboard - a GenericDesktop.SystemControl report for the system control keys, such as power and sleep - Consumer.ConsumerControl report for multimedia (forward, rewind, play/pause, mute, etc) and other extended keys. - additional output, vendor specific, and feature reports Splitting each report into a separate input device is wasteful and even hurts userspace as it makes it harder to determine the true capabilities (set of available keys) of a keyboard, so let's adjust application matching to merge system control and consumer control reports with keyboard report, if one has already been processed.
