With recent clockevent conversion, for typical r4k counter timer, setup_irq() for the timer interrupt is called three times. 1. from time_init() (#ifdef CONFIG_IRQ_CPU block) 2. from plat_timer_setup() (arch/tx4927/common/tx4927_setup.c, for example) 3. from mips_clockevent_init() Which one should remain? Also I found mips_timer_ack and cycles_per_jiffy are not used now. Can we remove them entirely? Furthermore, I wonder how to disable mips_clockevent_device even if the CPU has r4k counter. For example, pnx8550 has the r4k counter but needs special mips_timer_ack and clocksource_mips.read routine. I suppose current time code is broken for such platforms. Any suggestions? --- Atsushi Nemoto
