2013-11-14ACPI / driver core: Store an ACPI device pointer in struct acpi_dev_nodeRafael J. Wysocki
Modify struct acpi_dev_node to contain a pointer to struct acpi_device associated with the given device object (that is, its ACPI companion device) instead of an ACPI handle corresponding to it. Introduce two new macros for manipulating that pointer in a CONFIG_ACPI-safe way, ACPI_COMPANION() and ACPI_COMPANION_SET(), and rework the ACPI_HANDLE() macro to take the above changes into account. Drop the ACPI_HANDLE_SET() macro entirely and rework its users to use ACPI_COMPANION_SET() instead. For some of them who used to pass the result of acpi_get_child() directly to ACPI_HANDLE_SET() introduce a helper routine acpi_preset_companion() doing an equivalent thing. The main motivation for doing this is that there are things represented by struct acpi_device objects that don't have valid ACPI handles (so called fixed ACPI hardware features, such as power and sleep buttons) and we would like to create platform device objects for them and "glue" them to their ACPI companions in the usual way (which currently is impossible due to the lack of valid ACPI handles). However, there are more reasons why it may be useful. First, struct acpi_device pointers allow of much better type checking than void pointers which are ACPI handles, so it should be more difficult to write buggy code using modified struct acpi_dev_node and the new macros. Second, the change should help to reduce (over time) the number of places in which the result of ACPI_HANDLE() is passed to acpi_bus_get_device() in order to obtain a pointer to the struct acpi_device associated with the given "physical" device, because now that pointer is returned by ACPI_COMPANION() directly. Finally, the change should make it easier to write generic code that will build both for CONFIG_ACPI set and unset without adding explicit compiler directives to it. Signed-off-by: Rafael J.

The right motor is can be used to create a weak rumble effect but does not allow to set the force. The left motor is used to create a strong rumble effect with adjustable intensity. The state of both motors can be changed using HID_OUTPUT_REPORT packets and have no timing information. FF memless is used to keep track of the timing and the sony driver just generates the necessary URBs. Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-11-11HID: don't ignore eGalax/D-Wav/EETI HIDsForest Bond
Certain devices with class HID, protocol None did not work with the HID driver at one point, and as a result were bound to usbtouchscreen instead as of commit 139ebe8 ("Input: usbtouchscreen - fix eGalax HID ignoring"). This change was prompted by the following report: https://lkml.org/lkml/2009/1/25/127 Unfortunately, the device mentioned in this report is no longer available for testing. We've recently discovered that some devices with class HID, protocol None do not work with usbtouchscreen, but do work with usbhid. Here is the report that made this evident: http://comments.gmane.org/gmane.linux.kernel.input/31710 Driver binding for these devices has flip-flopped a few times, so both of the above reports were regressions. This situation would appear to leave us with no easy way to bind every device to the right driver. However, in my own testing with several devices I have not found a device with class HID that does not work with the current HID driver. It is my belief that changes to the HID driver since the original report have likely fixed the issue(s) that made it unsuitable at the time, and that we should prefer it over usbtouchscreen for these devices. In particular, HID quirks affecting these devices were added/removed in the following commits since then: fe6065d HID: add multi-input quirk for eGalax Touchcontroller 77933c3 Merge branch 'egalax' into for-linus ebd11fe HID: Add quirk for eGalax touch controler. d34c4aa HID: add no-get quirk for eGalax touch controller This patch makes the HID driver no longer ignore eGalax/D-Wav/EETI devices with class HID. If there are in fact devices with class HID that still do not work with the HID driver, we will see another round of regressions. In that case I propose we investigate why the device is not working with the HID driver rather than re-introduce regressions for functioning HID devices by again binding them to usbtouchscreen. The corresponding change to usbtouchscreen will be made separately. Signed-off-by: Forest Bond <forest.bond@rapidrollout.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

But the current driver has a bug and not taking account for report count field. This causes user space to see only 4 bytes of data sent via IIO interface.

2013-10-30HID: wiimote: add pro-controller analog stick calibrationDavid Herrmann
The analog sticks of the pro-controller might report slightly off values. To guarantee a uniform setup, we now calibrate analog-stick values during pro-controller setup. Unfortunately, the pro-controller fails during normal EEPROM reads and I couldn't figure out whether there are any calibration values stored on the device. Therefore, we now use the first values reported by the device (iff they are not _way_ off, which would indicate movement) to initialize the calibration values. To allow users to change this calibration data, we provide a pro_calib sysfs attribute. We also change the "flat" values so user-space correctly smoothes our data. It makes slightly off zero-positions less visible while still guaranteeing highly precise movement reports. Note that the pro controller reports zero-positions in a quite huge range (at least: -100 to +100).

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.

2013-10-07HID: wiimote: fix FF deadlockDavid Herrmann
The input core has an internal spinlock that is acquired during event injection via input_event() and friends but also held during FF callbacks. That means, there is no way to share a lock between event-injection and FF handling. Unfortunately, this is what is required for wiimote state tracking and what we do with state.lock and input->lock. This deadlock can be triggered when using continuous data reporting and FF on a wiimote device at the same time. I takes me at least 30m of stress-testing to trigger it but users reported considerably shorter times (http://bpaste.net/show/132504/) when using some gaming-console emulators. The real problem is that we have two copies of internal state, one in the wiimote objects and the other in the input device. As the input-lock is not supposed to be accessed from outside of input-core, we have no other chance than offloading FF handling into a worker. This actually works pretty nice and also allows to implictly merge fast rumble changes into a single request. Due to the 3-layered workers (rumble+queue+l2cap) this might reduce FF responsiveness. Initial tests were fine so lets fix the race first and if it turns out to be too slow we can always handle FF out-of-band and skip the queue-worker.

2013-09-26HID: uhid: allocate static minorDavid Herrmann
udev has this nice feature of creating "dead" /dev/<node> device-nodes if it finds a devnode:<node> modalias. Once the node is accessed, the kernel automatically loads the module that provides the node. However, this requires udev to know the major:minor code to use for the node. This feature was introduced by: commit 578454ff7eab61d13a26b568f99a89a2c9edc881 Author: Kay Sievers <kay.sievers@vrfy.org> Date: Thu May 20 18:07:20 2010 +0200 driver core: add devname module aliases to allow module on-demand auto-loading However, uhid uses dynamic minor numbers so this doesn't actually work. We need to load uhid to know which minor it's going to use. Hence, allocate a static minor (just like uinput does) and we're good to go.
