Hi all, I was trying to use the userspace program given in Documentation/hpet.txt and i could not get it working. The HPET_IE_ON ioctl was failing. My HPET has 3 64 bit timers as I can see from the dmesg and they use interrups 2, 8, and 0. The zero is creating the problem in the function hpet_ioctl_ieon and causes an -EIO to be returned because the IRQ is zero. hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0 hpet0: 3 64-bit timers, 14318180 Hz My /proc/interrupts shows me that IRQ 0 is timer and 8 is rtc. So, if am correct, i should be given the IRQ 2. But surprisingly the hpet_open function finds other hpet timers to be either open or busy and returns the last one with irq 0.
