2009-06-12HID: use debugfs for events/reports dumpingJiri Kosina
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>
2009-06-12HID: use debugfs for report dumping descriptorJiri Kosina
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>
2009-05-20HID: add new multitouch and digitizer contantsStephane Chatty
Added constants to hid.h for all digitizer usages (including the new multitouch ones that are not yet in the official USB spec but are being pushed by Microsft as described in their paper "Digitizer Drivers for Windows Touch and Pen-Based Computers"). Updated hid-debug.c to support the new MT input constants such as ABS_MT_POSITION_X. Signed-off-by: Stephane Chatty <chatty@enac.fr> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2009-03-30HID: remove compat stuffJiri Slaby
This removal was scheduled and there is no problem with later distros to adapt for the new bus, thanks to aliases. module-init-tools map files are deprecated nowadays, so that the patch which introduced hid ones into the m-i-t won't be accepted and hence there is no reason for leaving compat stuff in.

2009-03-30HID: bring back possibility to specify vid/pid ignore on module loadJiri Kosina
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. So keep this quirk flag in place for backwards compatibility. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2009-03-25HID: autosuspend support for USB HIDOliver Neukum
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.

2008-10-27HID: fix oops during suspend of unbound HID devicesJiri Slaby
Usbhid structure is allocated on start invoked only from probe of some driver. When there is no driver, the structure is null and causes null-dereference oopses. Fix it by allocating the structure on probe and disconnect of the device itself. Also make sure we won't race between start and resume or stop and suspend respectively.

2008-10-14HID: fix a lockup regression when using force feedback on a PID deviceAnssi Hannula
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.

2008-05-20HID: split Numlock emulation quirk from HID_QUIRK_APPLE_HAS_FN.Diego 'Flameeyes' Petteno
Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for non-laptop Apple keyboards of the Aluminium series. The USB version of these don't need Numlock emulation, like the laptop (and Aluminium Wireless) do, as they have a proper keypad. This patch splits the Numlock emulation for Apple keyboards in a different quirk flag, so that it can be enabled for all the keyboards but the Aluminium USB ones. If the Numlock emulation is enabled for Aluminium USB keyboards, the JKL and UIO keys become the numeric pad, and the rest of the keyboard is disabled, included the key used to disable Numlock. Additionally, these keyboard should not have a Numlock at all, as the Numlock key is instead replaced by the 'Clear' key as usual for Apple USB keyboards.
