The first way uses the - * ppsapi STREAMS module and the LDISC_PPS line discipline, while the - * second way uses the ppsclock STREAMS module and the LDISC_PPS line - * discipline. Either of these works only for the baseboard serial ports - * of the Sun SPARC IPC and clones. However, the ppsapi uses the - * proposed IETF interface expected to become standard for PPS signals. - * The serial port to be used is specified by the pps command in the - * configuration file. This driver reads the timestamp directly by a - * designated ioctl() system call. + * Both methods require a modified device driver and kernel interface + * compatible with the Pulse-per-Second API for Unix-like Operating + * Systems, Version 1.0, RFC-2783 (PPSAPI). Implementations are + * available for FreeBSD, Linux, SunOS, Solaris and Alpha. However, at + * present only the Alpha implementation provides the full generality of + * the API with multiple PPS drivers and multiple handles per driver. * - * The third way uses the LDISC_CLKPPS line discipline and works for - * any architecture supporting a serial port. If after a few seconds - * this driver finds no ppsclock module configured, it attempts to open - * a serial port device /dev/pps%d, where %d is the unit number, and - * assign the LDISC_CLKPPS line discipline to it. If the line discipline - * fails, no harm is done except the accuracy is reduced somewhat. The - * pulse generator in the gadget box is adjusted to produce a start bit - * of length 26 usec at 38400 bps. Used with the LDISC_CLKPPS line - * discipline, this produces an ASCII DEL character ('\377') followed by - * a timestamp at each seconds epoch. + * In many configurations a single port is used for the radio timecode + * and PPS signal. In order to provide for this configuration and others + * involving dedicated multiple serial/parallel ports, the driver first + * attempts to open the device /dev/pps%d, where %d is the unit number. + * If this fails, the driver attempts to open the device specified by + * the pps configuration command. If a port is to be shared, the pps + * command must be placed before the radio device(s) and the radio + * device(s) must be placed before the PPS driver(s) in the + * configuration file. * - * The fourth way involves an auxiliary radio clock driver which calls - * the PPS driver with a timestamp captured by that driver. This use is - * documented in the source code for the driver(s) involved. Note that - * some drivers collect the sample information themselves before calling - * pps_sample(), and others call knowing only that they are running - * shortly after an on-time tick and they expect to retrieve the PPS - * offset, fudge their result, and insert it into the timestream. + * This driver normally uses the PLL/FLL clock discipline implemented in + * the ntpd code. If kernel support is available, the kernel PLL/FLL + * clock discipline is used instead. The default configuration is not to + * use the kernel PPS discipline, if present. The kernel PPS discipline + * can be enabled using the pps command. * * Fudge Factors * * There are no special fudge factors other than the generic. The fudge - * time1 parameter can be used to compensate for miscellaneous UART and - * OS delays. Allow about 247 us for uart delays at 38400 bps and about - * 1 ms for STREAMS nonsense with older workstations. Velocities may - * vary with modern workstations. + * time1 parameter can be used to compensate for miscellaneous device + * driver and OS delays. */ /* * Interface definitions */ #ifdef HAVE_PPSAPI -extern int pps_assert; +extern int pps_assert; /* selects rising or falling edge */ +extern int pps_hardpps; /* enables the kernel PPS interface */ +#define DEVICE "/dev/pps%d" /* device name and unit */ #endif /* HAVE_PPSAPI */ -#ifdef TTYCLK -#define DEVICE "/dev/pps%d" /* device name and unit */ -#ifdef B38400 -#define SPEED232 B38400 /* uart speed (38400 baud) */ -#else -#define SPEED232 EXTB /* as above */ -#endif -#endif /* TTYCLK */ #define PRECISION (-20) /* precision assumed (about 1 us) */ #define REFID "PPS\0" /* reference ID */ #define DESCRIPTION "PPS Clock Discipline" /* WRU */ +#define NANOSECOND 1000000000 /* one second (ns) */ +#define RANGEGATE 500000 /* range gate (ns) */ +#define ASTAGE 8 /* filter stages */ -#define FLAG_TTY 0x01 /* tty_clk heard from */ -#define FLAG_PPS 0x02 /* ppsclock heard from */ -#define FLAG_AUX 0x04 /* auxiliary PPS source */ - -static struct peer *pps_peer; /* atom driver for auxiliary PPS sources */ - -#ifdef TTYCLK -static void atom_receive P((struct recvbuf *)); -#endif /* TTYCLK */ +static struct peer *pps_peer; /* atom driver for PPS sources */ +#ifdef HAVE_PPSAPI /* - * Unit control structure + * PPS unit control structure */ -struct atomunit { -#ifdef HAVE_PPSAPI - pps_info_t pps_info; /* pps_info control */ -#endif /* HAVE_PPSAPI */ -#ifdef PPS - struct ppsclockev ev; /* ppsclock control */ -#endif /* PPS */ - int flags; /* flags that wave */ +struct ppsunit { + struct timespec ts; /* last timestamp */ + int fddev; /* pps device descriptor */ + pps_params_t pps_params; /* pps parameters */ + pps_info_t pps_info; /* last pps data */ + pps_handle_t handle; /* pps handlebars */ }; +#endif /* HAVE_PPSAPI */ /* * Function prototypes */ static int atom_start P((int, struct peer *)); -static void atom_shutdown P((int, struct peer *)); static void atom_poll P((int, struct peer *)); -#if defined(PPS) || defined(HAVE_PPSAPI) +#ifdef HAVE_PPSAPI +static void atom_shutdown P((int, struct peer *)); +static void atom_control P((int, struct refclockstat *, struct + refclockstat *, struct peer *)); static int atom_pps P((struct peer *)); -#endif /* PPS || HAVE_PPSAPI */ +static int atom_ppsapi P((struct peer *, int, int)); +#endif /* HAVE_PPSAPI */ /* * Transfer vector */ struct refclock refclock_atom = { atom_start, /* start up driver */ +#ifdef HAVE_PPSAPI atom_shutdown, /* shut down driver */ +#else + noentry, /* shut down driver */ +#endif /* HAVE_PPSAPI */ atom_poll, /* transmit poll message */ - noentry, /* not used (old atom_control) */ +#ifdef HAVE_PPSAPI + atom_control, /* fudge control */ +#else + noentry, /* fudge control */ +#endif /* HAVE_PPSAPI */ noentry, /* initialize driver */ noentry, /* not used (old atom_buginfo) */ NOFLAGS /* not used */ @@ -162,74 +142,142 @@ struct refclock refclock_atom = { */ static int atom_start( - int unit, - struct peer *peer + int unit, /* unit number (not used) */ + struct peer *peer /* peer structure pointer */ ) { - register struct atomunit *up; struct refclockproc *pp; - int flags; -#ifdef TTYCLK - int fd = 0; - char device[20]; - int ldisc = LDISC_CLKPPS; -#endif /* TTYCLK */ +#ifdef HAVE_PPSAPI + register struct ppsunit *up; + char device[80]; +#endif /* HAVE_PPSAPI */ + /* + * Allocate and initialize unit structure + */ pps_peer = peer; - flags = 0; + pp = peer->procptr; + peer->precision = PRECISION; + pp->clockdesc = DESCRIPTION; + memcpy((char *)&pp->refid, REFID, 4); + peer->burst = ASTAGE; + peer->stratum = STRATUM_UNSPEC; +#ifdef HAVE_PPSAPI + up = emalloc(sizeof(struct ppsunit)); + memset(up, 0, sizeof(struct ppsunit)); + pp->unitptr = (caddr_t)up; -#ifdef TTYCLK -# if defined(SCO5_CLOCK) - ldisc = LDISC_RAW; /* DCD timestamps without any line discipline */ -# endif /* - * Open serial port.
