2013-10-18HID: Fix unit exponent parsing againNikolai Kondrashov
Revert some changes done in 774638386826621c984ab6994439f474709cac5e. Revert all changes done in hidinput_calc_abs_res as it mistakingly used "Unit" item exponent nibbles to affect resolution value. This wasn't breaking resolution calculation of relevant axes of any existing devices, though, as they have only one dimension to their units and thus 1 in the corresponding nible. Revert to reading "Unit Exponent" item value as a signed integer in hid_parser_global to fix reading specification-complying values. This fixes resolution calculation of devices complying to the HID standard, including Huion, KYE, Waltop and UC-Logic graphics tablets which have their report descriptors fixed by the drivers. Explanations follow. There are two "unit exponents" in HID specification and it is important not to mix them. One is the global "Unit Exponent" item and another is nibble values in the global "Unit" item. See 6.2.2.7 Global Items. The "Unit Exponent" value is just a signed integer and is used to scale the integer resolution unit values, so fractions can be expressed. The nibbles of "Unit" value are used to select the unit system (nibble 0), and presence of a particular basic unit type in the unit formula and its *exponent* (or power, nibbles 1-6). And yes, the latter is in two complement and zero means absence of the unit type. Taking the representation example of (integer) joules from the specification: [mass(grams)][length(centimeters)^2][time(seconds)^-2] * 10^-7 the "Unit Exponent" would be -7 (or 0xF9, if stored as a byte) and the "Unit" value would be 0xE121, signifying: Nibble Part Value Meaning ----- ---- ----- ------- 0 System 1 SI Linear 1 Length 2 Centimeters^2 2 Mass 1 Grams 3 Time -2 Seconds^-2 To give the resolution in e.g. hundredth of joules the "Unit Exponent" item value should have been -9. See also the examples of "Unit" values for some common units in the same chapter. However, there is a common misunderstanding about the "Unit Exponent" value encoding, where it is assumed to be stored the same as nibbles in "Unit" item. This is most likely due to the specification being a bit vague and overloading the term "unit exponent". This also was and still is proliferated by the official "HID Descriptor Tool", which makes this mistake and stores "Unit Exponent" as such. This format is also mentioned in books such as "USB Complete" and in Microsoft's hardware design guides. As a result many devices currently on the market use this encoding and so the driver should support them.

2013-08-27HID: detect Win 8 multitouch devices in coreBenjamin Tissoires
Detecting Win 8 multitouch devices in core allows us to set quirks before the device is parsed through hid_hw_start(). It also simplifies the detection of those devices in hid-multitouch and makes the handling of those devices cleaner. As Win 8 multitouch panels are in the group multitouch and rely on a special feature to be detected, this patch adds a bitfield in the parser.

2013-08-27HID: Use hid_parser for pre-scanning the report descriptorsBenjamin Tissoires
The Win 8 detection is sufficiently complex to warrant use of the full parser code, in spite of the inferred memory usage. Therefore, we can use the existing HID parser in hid-core for hid_scan_report() by re-using the code from hid_open_report(). hid_parser_global, hid_parser_local and hid_parser_reserved does not have any side effects. We just need to reimplement the MAIN_ITEM callback to have a proper parsing without side effects.

2013-07-22HID: fix data access in implement()Jiri Kosina
implement() is setting bytes in LE data stream. In case the data is not aligned to 64bits, it reads past the allocated buffer. It doesn't really change any value there (it's properly bitmasked), but in case that this read past the boundary hits a page boundary, pagefault happens when accessing 64bits of 'x' in implement(), and kernel oopses. This happens much more often when numbered reports are in use, as the initial 8bit skip in the buffer makes the whole process work on values which are not aligned to 64bits. This problem dates back to attempts in 2005 and 2006 to make implement() and extract() as generic as possible, and even back then the problem was realized by Adam Kroperlin, but falsely assumed to be impossible to cause any harm: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg47690.html I have made several attempts at fixing it "on the spot" directly in implement(), but the results were horrible; the special casing for processing last 64bit chunk and switching to different math makes it unreadable mess. I therefore took a path to allocate a few bytes more which will never make it into final report, but are there as a cushion for all the 64bit math operations happening in implement() and extract(). All callers of hid_output_report() are converted at the same time to allocate the buffer by newly introduced hid_alloc_report_buf() helper. Bruno noticed that the whole raw_size test can be dropped as well, as hid_alloc_report_buf() makes sure that the buffer is always of a proper size.

This driver was originally written by James McKenzie, updated by Greg Kroah-Hartman, further updated by Bastien Nocera, with suspend support added. I ported it to the HID subsystem, in order to simplify it a litle and allow lirc to use it through hiddev. More recent versions of the IR receiver are also supported through a patch by Alex Karpenko. The patch also adds support for the 2nd and 5th generation of the controller, and the menu key on newer brushed metal remotes.

2013-03-01HID: Separate struct hid_device's driver_lock into two locks.Andrew de los Reyes
This patch separates struct hid_device's driver_lock into two. The goal is to allow hid device drivers to receive input during their probe() or remove() function calls. This is necessary because some drivers need to communicate with the device to determine parameters needed during probe (e.g., size of a multi-touch surface), and if possible, may perfer to communicate with a device on host-initiated disconnect (e.g., to put it into a low-power state). Historically, three functions used driver_lock: - hid_device_probe: blocks to acquire lock - hid_device_remove: blocks to acquire lock - hid_input_report: if locked returns -EBUSY, else acquires lock This patch adds another lock (driver_input_lock) which is used to block input from occurring. The lock behavior is now: - hid_device_probe: blocks to acq. driver_lock, then driver_input_lock - hid_device_remove: blocks to acq. driver_lock, then driver_input_lock - hid_input_report: if driver_input_lock locked returns -EBUSY, else acquires driver_input_lock This patch also adds two helper functions to be called during probe() or remove(): hid_device_io_start() and hid_device_io_stop(). These functions lock and unlock, respectively, driver_input_lock; they also make a note of whether they did so that hid-core knows if a driver has changed the lock state. This patch results in no behavior change for existing devices and drivers. However, during a probe() or remove() function call in a driver, that driver may now selectively call hid_device_io_start() to let input events come through, then optionally call hid_device_io_stop() to stop them.

2013-02-19HID: add ThingM blink(1) USB RGB LED supportVivien Didelot
The ThingM blink(1) is an open source hardware USB RGB LED. It contains an internal EEPROM, allowing to configure up to 12 light patterns. A light pattern is a RGB color plus a fade time. This driver registers a LED class instance with additional sysfs attributes to support basic functions such as setting RGB colors, fade and playing. Other functions are still accessible through the hidraw interface. At this time, the only documentation for the device is the firmware source code from ThingM, plus a few schematics. They are available at: https://github.com/todbot/blink1 This patch is version 3. It updates the name of the source file, the driver and the led sysfs entry, according to comments from Jiri Kosina and Simon Wood.
