I decided not to use the structures and functions - * provided by the kernel for two reasons: - * - * 1. Due to the planned use of "/proc" in the Neo driver, many - * of the functions of the "sysctl" interface would go unused. - * A simpler interface will be easier to maintain. - * - * 2. I'd rather divorce our "added package" from the kernel internals. - * If the "sysctl" structures should change, I will be insulated - * from those changes. These "/proc" entries won't be under the - * "sys" tree anyway, so there is no need to maintain a strict - * dependence relationship. - * - * Author: - * - * Scott H Kilau - * - */ - -#ifndef _DGNC_RW_PROC_H -#define _DGNC_RW_PROC_H - -/* - * The list of DGNC entries with r/w capabilities. - * These magic numbers are used for identification purposes. - */ -enum { - DGNC_INFO = 1, /* Get info about the running module */ - DGNC_MKNOD = 2, /* Get info about driver devices */ - DGNC_BOARD_INFO = 3, /* Get info about the specific board */ - DGNC_BOARD_VPD = 4, /* Get info about the board's VPD */ - DGNC_BOARD_TTYSTATS = 5, /* Get info about the board's tty stats */ - DGNC_BOARD_TTYINTR = 6, /* Get info about the board's tty intrs */ - DGNC_BOARD_TTYFLAGS = 7, /* Get info about the board's tty flags */ - DGNC_BOARD_MKNOD = 8, /* Get info about board devices */ - DGNC_PORT_INFO = 9, /* Get info about the specific port */ - DGNC_PORT_SNIFF = 10, /* Sniff data in/out of specific port */ - DGNC_PORT_CUSTOM_TTYNAME = 11, /* Get info about UDEV tty name */ - DGNC_PORT_CUSTOM_PRNAME = 12, /* Get info about UDEV pr name */ -}; - -/* - * Directions for proc handlers - */ -enum { - INBOUND = 1, /* Data being written to kernel */ - OUTBOUND = 2, /* Data being read from the kernel */ -}; - -/* - * Each entry in a DGNC proc directory is described with a - * "dgnc_proc_entry" structure.
