| * Input: psmouse - make sure we don't schedule reconnects after cleanupDmitry Torokhov2010-02-08
| | | | | | | | | | | | | | | | | | Set state of the device as "initializing" during and after cleanup to ensure that unsolicited data from the device is not passed on. We especially want to avoid processing new device announcements "0xaa 0x00" that can come up before we perform reconnect operation. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

| | | | | | | | | | | | | | | | | | | | | | | | For pressure-based multi-touch devices, a direct way to send sensor intensity data per finger is needed. This patch adds the ABS_MT_PRESSURE event to the MT protocol.

| * Input: add compat support for sysfs and /proc capabilities outputDmitry Torokhov2010-01-12
| | | | | | | | | | | | | | | | | | | | | | | | Input core displays capabilities bitmasks in form of one or more longs printed in hex form and separated by spaces. Unfortunately it does not work well for 32-bit applications running on 64-bit kernels since applications expect that number is "worth" only 32 bits when kernel advances by 64 bits. Fix that by ensuring that output produced for compat tasks uses 32-bit units. Reported-and-tested-by: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For configurations where Synaptics hardware is present but the Synaptics extensions support is not compiled in, the mouse is reprobed and a new device is allocated on every suspend/resume. During probe, psmouse_switch_protocol() calls psmouse_extensions() with set_properties=1. This calls the dummy synaptics_init() which returns an error code, instructing us not to use the synaptics extensions. During resume, psmouse_reconnect() calls psmouse_extensions() with set_properties=0, in which case call to synaptics_init() is bypassed and PSMOUSE_SYNAPTICS is returned. Since the result is different from previous attempt psmouse_reconnect() fails and full re-probe happens. Fix this by tweaking the set_properties=0 codepath in psmouse_extensions() to be more careful about offering PSMOUSE_SYNAPTICS extensions.

| * Input: evdev - be less aggressive about sending SIGIO notifiesAdam Jackson2010-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using realtime signals, we'll enqueue one signal for every event. This is unfortunate, because (for example) keyboard presses are three events: key, msc scancode, and syn. They'll be enqueued fast enough in kernel space that all three events will be ready to read by the time userspace runs, so the first invocation of the signal handler will read all three events, but then the second two invocations still have to run to do no work. Instead, only send the SIGIO notification on syn events. This is a slight abuse of SIGIO semantics, in principle it ought to fire as soon as any events are readable. But it matches evdev semantics, which is more important since SIGIO is rather vaguely defined to begin with.

| * Input: atkbd - fix canceling event_work in disconnectDmitry Torokhov2010-01-06
| | | | | | | | | | | | | | | | We need to first unregister input device and only then cancel event work since events can arrive (and cause event work to get scheduled again) until input_unregister_device() returns. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs_remove_group() waits for sysfs attributes to be removed, therefore we do not need to worry about driver-specific attributes being accessed after driver has been detached from the device. In fact, attempts to take serio->drv_mutex in attribute methods may lead to the following deadlock: sysfs_read_file() fill_read_buffer() sysfs_get_active_two() psmouse_attr_show_helper() serio_pin_driver() serio_disconnect_driver() mutex_lock(&serio->drv_mutex); <--------> mutex_lock(&serio_drv_mutex); psmouse_disconnect() sysfs_remove_group(... psmouse_attr_group); .... sysfs_deactivate(); wait_for_completion(); Fix this by removing calls to serio_[un]pin_driver() and functions themselves and using driver-private mutexes to serialize access to attribute's set() methods that may change device state.

Having 'gain' being unsigned int was an unfortunate choice since it dominates all implicit type conversions causing everything to be treated as unsigned int. Let's change it back to signed int and simply add proper casts to rumble effect calculations.
