    Where is the u64? My (x86_64) copy of /usr/include/linux/hpet.h looks like:

    1 #ifndef __HPET__
    2 #define __HPET__ 1
    3
    4
    5
    6
    7 struct hpet_info {
    8 unsigned long hi_ireqfreq; /* Hz */
    9 unsigned long hi_flags; /* information */
    10 unsigned short hi_hpet;
    11 unsigned short hi_timer;
    12 };
    13
    14 #define HPET_INFO_PERIODIC 0x0010 /* periodic-capable comparator */
    15
    16 #define HPET_IE_ON _IO('h', 0x01) /* interrupt on */
    17 #define HPET_IE_OFF _IO('h', 0x02) /* interrupt off */
    18 #define HPET_INFO _IOR('h', 0x03, struct hpet_info)
    19 #define HPET_EPI _IO('h', 0x04) /* enable periodic */
    20 #define HPET_DPI _IO('h', 0x05) /* disable periodic */
    21 #define HPET_IRQFREQ _IOW('h', 0x6, unsigned long) /* IRQFREQ usec */
    22
    23 #endif /* !__HPET__ */

    I guess s390 hpet.h looks different? Does it just need to #include <linux/types.h> ?
    Or is the problem the kernel-space u64 vs. userspace __u64?

    Any suggestions?
