2024-07-01HID: bpf: Thrustmaster TCA Yoke Boeing joystick fixBenjamin Tissoires1-0/+144
This joystick's original HID descriptor is wrong & it shows a ABS_MISC axis in Linux that doesn't exist on the hardware.

2024-07-01HID: bpf: Add Huion Dial 2 bpf fixupBenjamin Tissoires2-0/+615
Pretty much similar to the Inspiroy 2, but with 2 wheels and 8 buttons. This bpf also works in both normal and vendor mode. If the device is switched into vendor mode by huion-switcher, a udev property is set which is then retrieved by this bpf object. This allows to hide the now unused normal collections.

2024-07-01HID: bpf: add a driver for the Huion Inspiroy 2S (H641P)Benjamin Tissoires1-0/+534
This is a a driver for the Huion Inspiroy 2S in both modes (firmware mode and tablet mode). This device has 6 buttons and a wheel, all of which send key combinations (see the comments for the defaults). Luckily the device is quite limited in that it only supports one button down at a time, so with this BPF we can simply remap the 8 possible report IDs to our own custom-built report descriptor. If the device is in tablet mode (e.g. using huion-switcher it sends everything through the vendor report instead). This BPF program converts both, depending which devices you attach to you get both. Or if you attach to all hid devices you get a duplicate device but it'll work either way. This BPF should be mostly compatible for the M and L as well though they have more buttons so the rdescs will need some minor rework.

2024-07-01HID: bpf: Add a HID report composition helper macrosBenjamin Tissoires1-0/+2960
These macros make it slightly easier and more modular to create a HID report descriptor from scratch. Since they carry the annotation we don't need to comment it and they cannot get stale. For comparison, before we had this: 0x15, 0x00, // Logical Minimum (0) 0x25, 0x01, // Logical Maximum (1) 0x95, 0x04, // Report Count (4) 0x75, 0x01, // Report Size (1) Now we can write this as: LogicalRange_i8(0, 1) ReportCount(4) ReportSize(1) Because these macros are for creating new report descriptors, some bits aren't directly exposed. e.g in the example above: there is a logical range as one macro that sets both min and max. There is seldom a good use case for skipping either anyway. These macros will need to be expanded over time. For Usage Pages and Usage IDs, we use a tool to parse the HUT JSON (attached to the HUT 1.5 PDF [1]) and generate all #defines for all usage pages and usages in the form: #define UsagePage_Foo_Bar #define Usage_FB_SomeOrOther Where the FB is simply the acronym based on the capital letters in the Usage Page name or the first three letters, whichever makes slightly more sense.

2024-05-07HID: bpf: add in-tree HID-BPF fix for the Huion Kamvas Pro 19Benjamin Tissoires1-0/+290
This tablets gets a lot of things wrong: - the secondary button is reported through Secondary Tip Switch - the third button is reported through Invert Fortunately, before entering eraser mode, (so Invert = 1), the tablet always sends an out-of-proximity event. So we can detect that single event and: - if there was none but the invert bit was toggled: this is the third button - if there was this out-of-proximity event, we are entering eraser mode, and we will until the next out-of-proximity.

2024-05-07HID: bpf: add in-tree HID-BPF fix for the XBox Elite 2 over BluetoothBenjamin Tissoires1-0/+133
When using the XBox Wireless Controller Elite 2 over Bluetooth, the device exports the paddle on the back of the device as a single bitfield value of usage "Assign Selection". The kernel doesn't process those usages properly and report KEY_UNKNOWN for it. SDL doesn't know how to interprete that KEY_UNKNOWN and thus ignores the paddles. Given that over USB the kernel uses BTN_TRIGGER_HAPPY[5-8], we can tweak the report descriptor to make the kernel interprete it properly: - we need an application collection of gamepad (so we have to close the current Consumer Control one) - we need to change the usage to be buttons from 0x15 to 0x18 Link: https://lore.kernel.org/r/[email protected] Reviewed-by: Peter Hutterer <[email protected]> Signed-off-by: Benjamin Tissoires <[email protected]>
2024-05-07HID: bpf: add in-tree HID-BPF fix for the Wacom ArtPenBenjamin Tissoires1-0/+173
This pen is compatible with multiple Wacom tablets, but we only add support for the Intuos Pro 2 M, as this is the one our user reported the bug against. We can not generically add all compatible Wacom tablets as we are writing the offsets by hand. The point of this HID-BPF program is to work around a firmware limitation where the pressure is repeated every other report. Given that we know this will happen, we can change the first new pressure information with the mean compared to the previous one. This way we smooth the incoming pressure without losing information.

2024-05-07HID: bpf: add first in-tree HID-BPF fix for the XPPen Artist 24Benjamin Tissoires5-0/+605
This commit adds a fix for XPPen Artist 24 where the second button on the pen is used as an eraser. It's a "feature" from Microsoft, but it turns out that it's actually painful for artists. So we ship here a HID-BPF program that turns this second button into an actual button. Note that the HID-BPF program is not directly loaded by the kernel itself but by udev-hid-bpf[0]. But having the sources here allows us to also integrate tests into tools/testing/selftests/hid to ensure the HID-BPF program are actually tested.
