    Суть задачи: Сейчас драйвер ловит прерывание по GPIO, и драйвер посылает сигнал приложению. Многопоточное приложение не может отловить сигнал. Однопоточное приложение нормально ловит сигнал. Задачи: 1. Настроить, чтобы многопоточное приложение ловило сигнал. 2. Настроить получение прерывания GPIO приложением userspace. Чтобы не драйвер отлавливал GPIO прерывание, а userspace.
