Shared memory * layout etc is internal to the driver and described within farsync.c. * Overlap exists in that the values used for some fields within the * ioctl interface extend into the cards firmware interface so values in * this file may not be changed arbitrarily. */ /* What's in a name * * The project name for this driver is Oscar. The driver is intended to be * used with the FarSite T-Series cards (T2P & T4P) running in the high * speed frame shifter mode. This is sometimes referred to as X.21 mode * which is a complete misnomer as the card continues to support V.24 and * V.35 as well as X.21. * * A short common prefix is useful for routines within the driver to avoid * conflict with other similar drivers and I chosen to use "fst_" for this * purpose (FarSite T-series). * * Finally the device driver needs a short network interface name. Since * "hdlc" is already in use I've chosen the even less informative "sync" * for the present. */ #define FST_NAME "fst" /* In debug/info etc */ #define FST_NDEV_NAME "sync" /* For net interface */ #define FST_DEV_NAME "farsync" /* For misc interfaces */ /* User version number * * This version number is incremented with each official release of the * package and is a simplified number for normal user reference. * Individual files are tracked by the version control system and may * have individual versions (or IDs) that move much faster than the * the release version as individual updates are tracked. */ #define FST_USER_VERSION "1.04" /* Ioctl call command values */ #define FSTWRITE (SIOCDEVPRIVATE+10) #define FSTCPURESET (SIOCDEVPRIVATE+11) #define FSTCPURELEASE (SIOCDEVPRIVATE+12) #define FSTGETCONF (SIOCDEVPRIVATE+13) #define FSTSETCONF (SIOCDEVPRIVATE+14) /* FSTWRITE * * Used to write a block of data (firmware etc) before the card is running */ struct fstioc_write { unsigned int size; unsigned int offset; unsigned char data[]; }; /* FSTCPURESET and FSTCPURELEASE * * These take no additional data. * FSTCPURESET forces the cards CPU into a reset state and holds it there. * FSTCPURELEASE releases the CPU from this reset state allowing it to run, * the reset vector should be setup before this ioctl is run. */ /* FSTGETCONF and FSTSETCONF * * Get and set a card/ports configuration. * In order to allow selective setting of items and for the kernel to * indicate a partial status response the first field "valid" is a bitmask * indicating which other fields in the structure are valid. * Many of the field names in this structure match those used in the * firmware shared memory configuration interface and come originally from * the NT header file Smc.h * * When used with FSTGETCONF this structure should be zeroed before use. * This is to allow for possible future expansion when some of the fields * might be used to indicate a different (expanded) structure. */ struct fstioc_info { unsigned int valid; /* Bits of structure that are valid */ unsigned int nports; /* Number of serial ports */ unsigned int type; /* Type index of card */ unsigned int state; /* State of card */ unsigned int index; /* Index of port ioctl was issued on */ unsigned int smcFirmwareVersion; unsigned long kernelVersion; /* What Kernel version we are working with */ unsigned short lineInterface; /* Physical interface type */ unsigned char proto; /* Line protocol */ unsigned char internalClock; /* 1 => internal clock, 0 => external */ unsigned int lineSpeed; /* Speed in bps */ unsigned int v24IpSts; /* V.24 control input status */ unsigned int v24OpSts; /* V.24 control output status */ unsigned short clockStatus; /* lsb: 0=> present, 1=> absent */ unsigned short cableStatus; /* lsb: 0=> present, 1=> absent */ unsigned short cardMode; /* lsb: LED id mode */ unsigned short debug; /* Debug flags */ unsigned char transparentMode; /* Not used always 0 */ unsigned char invertClock; /* Invert clock feature for syncing */ unsigned char startingSlot; /* Time slot to use for start of tx */ unsigned char clockSource; /* External or internal */ unsigned char framing; /* E1, T1 or J1 */ unsigned char structure; /* unframed, double, crc4, f4, f12, */ /* f24 f72 */ unsigned char interface; /* rj48c or bnc */ unsigned char coding; /* hdb3 b8zs */ unsigned char lineBuildOut; /* 0, -7.5, -15, -22 */ unsigned char equalizer; /* short or lon haul settings */ unsigned char loopMode; /* various loopbacks */ unsigned char range; /* cable lengths */ unsigned char txBufferMode; /* tx elastic buffer depth */ unsigned char rxBufferMode; /* rx elastic buffer depth */ unsigned char losThreshold; /* Attenuation on LOS signal */ unsigned char idleCode; /* Value to send as idle timeslot */ unsigned int receiveBufferDelay; /* delay thro rx buffer timeslots */ unsigned int framingErrorCount; /* framing errors */ unsigned int codeViolationCount; /* code violations */ unsigned int crcErrorCount; /* CRC errors */ int lineAttenuation; /* in dB*/ unsigned short lossOfSignal; unsigned short receiveRemoteAlarm; unsigned short alarmIndicationSignal; }; /* "valid" bitmask */ #define FSTVAL_NONE 0x00000000 /* Nothing valid (firmware not running). * Slight misnomer.
