Input: feed more data into entropy pool

2016-05-19T16:35:18+00:00

Commit 4369c64c79a22 ("Input: Send events one packet at a time")
significantly reduced amount of entropy input core was feeding to the rest
of the system, because only the very first event in the event block would
be used as source of entropy.

With this change we will be calling add_input_randomness() for every event
that is not filtered by the input core as a duplicate. In addition, all
EV_SYN events are ignored.

drivers/input: eliminate INPUT_COMPAT_TEST macro

2016-03-25T23:37:42+00:00

INPUT_COMPAT_TEST became much simpler after commit f4056b52845283
("input: redefine INPUT_COMPAT_TEST as in_compat_syscall()") so we can
cleanly eliminate it altogether.

Input: improve autorepeat initialization

2015-10-14T06:30:31+00:00

Add new function input_enable_softrepeat() that allows drivers to
initialize their own values for input_dev->rep[REP_DELAY] and
input_dev->rep[REP_PERIOD], but also use the software autorepeat
functionality from input.c.

For example, a HID driver could do:

static void xyz_input_configured(struct hid_device *hid,
                                 struct hid_input *hidinput)
{
        input_enable_softrepeat(hidinput->input, 400, 100);
}

static struct hid_driver xyz_driver = {
        .input_configured = xyz_input_configured,
}

Input: do not emit unneeded EV_SYN when suspending

2015-08-07T21:55:38+00:00

Do not emit EV_SYN/SYN_REPORT on suspend if there were no keys that are
still pressed as we are suspending the device (and in all other cases when
input core is forcibly releasing keys via input_dev_release_keys() call).

Input: use for_each_set_bit() where appropriate

2015-06-25T21:44:36+00:00

Instead of iterating over all bits in a bitmap and test them individually
let's siwtch to for_each_set_bit() which is more compact and is also
faster.

Also use bitmap_weight() when counting number of set bits.

This also fixes INPUT_DO_TOGGLE() implementation as it should have used
*_CNT as the upper boundary, not *_MAX.

Input: do not try to filter out events if handler is not a filter

2015-01-08T21:53:34+00:00

If given input handler is not a filter there is no point is iterating list
of events in a packet to see if some of them need to be filtered out.

Input: small tweak to autorepeat handling

2015-01-08T21:53:30+00:00

If a device does not support autorepeat or does not emit any key events we
should not be scanning all events in a packet to decide if we should start
or stop autorepeat function.

Input: optimize events_per_packet count calculation

2014-12-16T05:45:55+00:00

This patch avoids unnecessary operations while estimating events per
packet for an input device when event type is not set.
