Since this is not -RT specific at all, do you mind routing it via ARM/ clocksource folks? They also may have an idea what is stopping them from using clocksource_of_init() so you wouldn't have to disable interrupts here. > /* channel 2: periodic and oneshot timer support */ > ret = setup_clkevents(tc, clk32k_divisor_idx); > if (ret) Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
