* HID: add HID_QUIRK_HIDINPUT_FORCEDaniel Mack2010-07-19
| | | | | | | | | | | For devices with exotic HID report descriptors, it might be necessary to make the HID core force the registration of an input device. Make that possible by introducing a new quirk type.

* / HID: add HID_QUIRK_HIDDEV_FORCE and HID_QUIRK_NO_IGNOREBastien Nocera2010-04-19
|/ | | | | | | | | | | | | | | | | | Add two quirks to make it possible for usbhid module options to override whether a device is ignored (HID_QUIRK_NO_IGNORE) and whether to connect a hiddev device (HID_QUIRK_HIDDEV_FORCE). Passing HID_QUIRK_NO_IGNORE for your device means that it will not be ignored by the HID layer, even if present in a blacklist. HID_QUIRK_HIDDEV_FORCE will force the creation of a hiddev for that device, making it accessible from user-space. Tested with an Apple IR Receiver, switching it from using appleir to using lirc's macmini driver. Signed-off-by: Bastien Nocera <hadess@hadess.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| * HID: Export hid_register_reportMichael Poole2010-02-10
| | | | | | | | | | | | | | | | | | | | The Apple Magic Mouse (and probably other devices) publish reports that are not called out in their HID report descriptors -- they only send them when enabled through other writes to the device. This allows a driver to handle these unlisted reports. Signed-off-by: Michael Poole <mdpoole@troilus.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
| * HID: make raw reports possible for both feature and output reportsJiri Kosina2010-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 2da31939a42 ("Bluetooth: Implement raw output support for HIDP layer"), support for Bluetooth hid_output_raw_report was added, but it pushes the data to the intr socket instead of the ctrl one. This has been fixed by 6bf8268f9a91f1 ("Bluetooth: Use the control channel for raw HID reports") Still, it is necessary to distinguish whether the report in question should be either FEATURE or OUTPUT. For this, we have to extend the generic HID API, so that hid_output_raw_report() callback provides means to specify this value so that it can be passed down to lower level hardware drivers (currently Bluetooth and USB).

* HID: fixup quirk for NCR devicesJiri Kosina2009-11-05
| | | | | | | | | | | | | | | | | | | | | NCR devices are terminally broken by design -- they claim themselves to contain proper input applications in their HID report descriptor, but behave very badly if treated in standard way. According to NCR developers, the devices get confused when queried for reports in a standard way, rendering them unusable. NCR is shipping application called "RPSL" that can be used to drive these devices through hiddev, under the assumption that in-kernel driver doesn't perform initial report query. If it does, neither in-kernel nor hiddev-based driver can operate with these devices any more. Introduce a quirk that skips the report query for all NCR devices. The previous NOGET quirk was wrong and had been introduced because I misunderstood the nature of brokenness of these devices. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| * HID: use debugfs for events/reports dumpingJiri Kosina2009-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a followup patch to the one implemeting rdesc representation in debugfs rather than being dependent on compile-time CONFIG_HID_DEBUG setting. The API of the appropriate formatting functions is slightly modified -- if they are passed seq_file pointer, the one-shot output for 'rdesc' file mode is used, and therefore the message is formatted into the corresponding seq_file immediately. Otherwise the called function allocated a new buffer, formats the text into the buffer and returns the pointer to it, so that it can be queued into the ring-buffer of the processess blocked waiting on input on 'events' file in debugfs. 'debug' parameter to the 'hid' module is now used solely for the prupose of inetrnal driver state debugging (parser, transport, etc). Signed-off-by: Jiri Kosina <jkosina@suse.cz>
| * HID: use debugfs for report dumping descriptorJiri Kosina2009-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is a little bit inconvenient for people who have some non-standard HID hardware (usually violating the HID specification) to have to recompile kernel with CONFIG_HID_DEBUG to be able to see kernel's perspective of the HID report descriptor and observe the parsed events. Plus the messages are then mixed up inconveniently with the rest of the dmesg stuff. This patch implements /sys/kernel/debug/hid/<device>/rdesc file, which represents the kernel's view of report descriptor (both the raw report descriptor data and parsed contents). With all the device-specific debug data being available through debugfs, there is no need for keeping CONFIG_HID_DEBUG, as the 'debug' parameter to the hid module will now only output only driver-specific debugging options, which has absolutely minimal memory footprint, just a few error messages and one global flag (hid_debug). We use the current set of output formatting functions. The ones that need to be used both for one-shot rdesc seq_file and also for continuous flow of data (individual reports, as being sent by the device) distinguish according to the passed seq_file parameter, and if it is NULL, it still output to kernel ringbuffer, otherwise the corresponding seq_file is used for output. The format of the output is preserved. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| * HID: autosuspend support for USB HIDOliver Neukum2009-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This uses the USB busy mechanism for aggessive autosuspend of USB HID devices. It autosuspends all opened devices supporting remote wakeup after a timeout unless - output is being done to the device - a key is being held down (remote wakeup isn't triggered upon key release) - LED(s) are lit - hiddev is opened As in the current driver closed devices will be autosuspended even if they don't support remote wakeup. The patch is quite large because output to devices is done in hard interrupt context meaning a lot a queuing and locking had to be touched. The LED stuff has been solved by means of a simple counter. Additions to the generic HID code could be avoided. In addition it now covers hidraw. It contains an embryonic version of an API to let the generic HID code tell the lower levels which capabilities with respect to power management are needed.

* | HID: bring back possibility to specify vid/pid ignore on module loadJiri Kosina2009-03-30
|/ | | | | | | | | | | | | | | | When hid quirks were converted to specialized driver, the HID_QUIRK_IGNORE has been moved completely, as the hid_ignore_list[] has been moved into the generic code. However userspace already got used to the possibility that modprobing usbhid with 'quirks=vid:pid:0x4' makes the device ignored by usbhid driver.

* HID: fix a lockup regression when using force feedback on a PID deviceAnssi Hannula2008-10-14
| | | | | | | | | | | | | | | | | | | | | | | Commit 8006479c9b75fb6594a7b746af3d7f1fbb68f18f introduced a spinlock in input_dev->event_lock, which is locked when handling input events. However, the hid-pidff driver sleeps when handling events as it waits for reports being sent to the device before changing the report contents again. This causes a system lockup when trying to use force feedback with a PID device, a regression introduced in 2.6.24 and 2.6.23.15. Fix it by extracting the raw report data from struct hid_report immediately when hid_submit_report() is called, therefore allowing drivers to change the contents of struct hid_report immediately without affecting the already-queued transfer. In hid-pidff, re-add the removed usbhid_wait_io() to pidff_erase_effect() instead, to prevent a full report queue from causing the submission to fail, thus not freeing up device memory. pidff_erase_effect() is not called while dev->event_lock is held.
