Won't the same issue happen if we happen to schedule a different effect that would start at "now" time? We should not be "dropping" the new effect, at least not in core.

It also happens sometimes with an effect that has a length and a replay count greater than one at the time, when the effect ends and restarts again. > It looks to me xpad.c needs [more] love. I agree and will try to come up with a fix for the xpad driver. >> Signed-off-by: Felix Rueegg <felix.rueegg@gmail.com> >> --- >> drivers/input/ff-memless.c | 7 +++++-- >> 1 file changed, 5 insertions(+), 2 deletions(-) >> >> diff --git a/drivers/input/ff-memless.c b/drivers/input/ff-memless.c >> index 74c0d8c..2e06948 100644 >> --- a/drivers/input/ff-memless.c >> +++ b/drivers/input/ff-memless.c >> @@ -139,10 +139,13 @@ static void ml_schedule_timer(struct ml_device *ml) >> if (!test_bit(FF_EFFECT_STARTED, &state->flags)) >> continue; >> >> - if (test_bit(FF_EFFECT_PLAYING, &state->flags)) >> + if (test_bit(FF_EFFECT_PLAYING, &state->flags)) { >> next_at = calculate_next_time(state); >> - else >> + if (next_at == now) >> + continue; >> + } else { >> next_at = state->play_at; >> + } >> >> if (time_before_eq(now, next_at) && >> (++events == 1 || time_before(next_at, earliest))) >> -- >> 1.9.0 >> > Thanks. > -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

When an effect with zero replay length, zero replay delay and zero envelope attack length is uploaded, it is played and then scheduled to play again one timer tick later. This triggers a warning (URB submitted while active) in combination with the xpad driver. Skipping the rescheduling of this effect fixes the issue.
