HID: bpf: add heuristics to the Huion Inspiroy 2S eraser button
When pressing the phsyical eraser button (remapped by us to the
Secondary Barrel Switch) while the tip is down, the device
gives us several false reports with a Tip Switch 0:
press| |release
SBS: [0 0 ... 1 1 1 ... 1 0 0 0 0 0 0 ...]
TS: [1 1 ... 1 0 1 ... 1 1 0 0 0 1 1 ...]
In both press/release the number of Tip Switch 0 reports can be up to 4
and *sometimes* the Tip Switch is released in the same report
as the button press/release event.
Paper over this by forcing the tip down for a few reports if it was down
before the button toggled.

HID: bpf: Add support for the Waltop Batteryless Tablet
Several bugs as outlined in udev-hid-bpf#66 and udev-hid-bpf!198:
- pressure curve is far from linear
- tilt range is ±60, not ±127
- pressing the second button sets both tip down and
barrel switch
Fix the second button by adding a Secondary Barrel Switch in the
existing padding and check for the tip down/barrel switch down combo.
When both values become true at the same time, set the Secondary Barrel
Switch instead.
Implement a custom pressure curve that maps the hardware range 0-102
linearly to the logical range 0-1224, and maps the hardware range
103-2047 logarithmically to the logical range 1232-2047. This mapping
isn’t perfect, but it’s way more natural than the stock configuration.

HID: bpf: Add fixup for Logitech SpaceNavigator variants
The 3Dconnexion SpaceNavigator HID report descriptor declares its axis
data to be "relative" when it is actually "absolute". This quirk was
addressed in the kernel in 2.6.33, but some SpaceNavigator variants have
a slightly different report descriptor whose axis input items are at
different offsets than those assumed by the kernel fixup.
Add a BPF fixup to handle both sets of offsets for known SpaceNavigator
variants if the descriptor has not already been fixed by the kernel.

This assumes that the tablet has been switched into vendor mode (by

Huion's proprietary data format.
This has been tested using the PW600L pen, which does not have an
eraser. There is no expectation that a pen with an eraser will work at
this time.

HID: bpf: add a v6.11+ compatible BPF fixup for the XPPen ACK05 remote
With v6.11+, we can actually call hid_hw_output_report() and put the device
into raw mode, thus getting accurate events without being messed up.
Technically we could do the same on v6.10, but given that wayland, gnome
and KDE are still not capable of handling the dial, and that v6.10 is EOL,
we can safely save a little bit of compilation by only allowing v6.11+.
We can easily export the battery information to userspace by adding a
dedicated report. However, we need to cheat on the kernel to force it
not to query the battery by making the physical collection a stylus. The
kernel will then only rely on the events it gets from the device.

async_fun(hctx);
/* but we can also delay the call by 10 ms */

HID: bpf: Suppress bogus F13 trigger on Sirius keyboard full fan shortcut
The TUXEDO Sirius 16 Gen1 and the TUXEDO Sirius 16 Gen2 Notebooks have an
additional "fan" key next to F12.
Pressing it alone sends a F14 key press which can be bound by user space.
Pressing it while holding the FN key triggers two things:
- The EC firmware locks the fan speed of the internal fans at 100%
- F13 key press is registered which by default is already bound in xkb and
desktop environments (e.g. in KDE Plasma it launches system settings)
To avoid this unexpected double duty of the FN shortcut, this bpf program
suppresses the F13 key press.
