2020-12-16Merge branch 'for-5.11/core' into for-linusJiri Kosina1-2/+43
- increase of maximum HID report size to 16KB in order to support some of the modern devices, from Dean Camera - control interface support for hidraw, from Dean Camera - stylus battery reporting improvement, from Dmitry Torokhov
2020-11-27HID: hidraw: Add additional hidraw input/output report ioctls.Dean Camera1-2/+43
Currently the hidraw module can only read and write feature HID reports on demand, via dedicated ioctls. Input reports are read from the device through the read() interface, while output reports are written through the write interface(). This is insufficient; it is desirable in many situations to be able to read and write input and output reports through the control interface to cover additional scenarios: - Reading an input report by its report ID, to get initial state - Writing an input report, to set initial input state in the device - Reading an output report by its report ID, to obtain current state - Writing an output report by its report ID, out of band This patch adds these missing ioctl requests to read and write the remaining HID report types. Note that not all HID backends will neccesarily support this (e.g. while the USB link layer supports setting Input reports, others may not). Also included are documentation and example updates. The current hidraw documentation states that feature reports read from the device does *not* include the report ID, however this is not the case and the returned report will have its report ID prepended by conforming HID devices, as the report data sent from the device over the control endpoint must be indentical in format to those sent over the regular transport.

Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2014-04-01HID: uhid: Add UHID_CREATE2 + UHID_INPUT2Petri Gynther1-0/+11
UHID_CREATE2: HID report descriptor data (rd_data) is an array in struct uhid_create2_req, instead of a pointer. Enables use from languages that don't support pointers, e.g. Python. UHID_INPUT2: Data array is the last field of struct uhid_input2_req. Enables userspace to write only the required bytes to kernel (ev.type + ev.u.input2.size + the part of the data array that matters), instead of the entire struct uhid_input2_req. Note: UHID_CREATE2 increases the total size of struct uhid_event slightly, thus increasing the size of messages that are queued for userspace. However, this won't affect the userspace processing of these events.
