Released version 1.1 + * + * Theory of operation: + * + * A Watchdog Timer (WDT) is a hardware circuit that can + * reset the computer system in case of a software fault. + * You probably knew that already. + * + * Usually a userspace daemon will notify the kernel WDT driver + * via the /dev/watchdog special device file that userspace is + * still alive, at regular intervals. When such a notification + * occurs, the driver will usually tell the hardware watchdog + * that everything is in order, and that the watchdog should wait + * for yet another little while to reset the system. + * If userspace fails (RAM error, kernel bug, whatever), the + * notifications cease to occur, and the hardware watchdog will + * reset the system (causing a reboot) after the timeout occurs. + * + * Create device with: + * mknod /dev/watchdog c 10 130 + * + * For an example userspace keep-alive daemon, see: + * Documentation/watchdog/watchdog.txt + */ + +#include <linux/module.h> +#include <linux/moduleparam.h> +#include <linux/types.h> +#include <linux/miscdevice.h> +#include <linux/watchdog.h> +#include <linux/delay.h> +#include <linux/fs.h> +#include <linux/ioport.h> +#include <linux/notifier.h> +#include <linux/reboot.h> +#include <linux/init.h> +#include <linux/spinlock.h> + +#include <asm/io.h> +#include <asm/uaccess.h> +#include <asm/system.h> + +/* enable support for minutes as units? */ +/* (does not always work correctly, so disabled by default!) */ +#define SMSC_SUPPORT_MINUTES +#undef SMSC_SUPPORT_MINUTES + +#define MAX_TIMEOUT 255 + +#define UNIT_SECOND 0 +#define UNIT_MINUTE 1 + +#define MODNAME "smsc37b787_wdt: " +#define VERSION "1.1" + +#define IOPORT 0x3F0 +#define IOPORT_SIZE 2 +#define IODEV_NO 8 + +static int unit = UNIT_SECOND; /* timer's unit */ +static int timeout = 60; /* timeout value: default is 60 "units" */ +static unsigned long timer_enabled = 0; /* is the timer enabled? */ + +static char expect_close; /* is the close expected? */ + +static spinlock_t io_lock; /* to guard the watchdog from io races */ + +static int nowayout = WATCHDOG_NOWAYOUT; + +/* -- Low level function ----------------------------------------*/ + +/* unlock the IO chip */ + +static inline void open_io_config(void) +{ + outb(0x55, IOPORT); + mdelay(1); + outb(0x55, IOPORT); +} + +/* lock the IO chip */ +static inline void close_io_config(void) +{ + outb(0xAA, IOPORT); +} + +/* select the IO device */ +static inline void select_io_device(unsigned char devno) +{ + outb(0x07, IOPORT); + outb(devno, IOPORT+1); +} + +/* write to the control register */ +static inline void write_io_cr(unsigned char reg, unsigned char data) +{ + outb(reg, IOPORT); + outb(data, IOPORT+1); +} + +/* read from the control register */ +static inline char read_io_cr(unsigned char reg) +{ + outb(reg, IOPORT); + return inb(IOPORT+1); +} + +/* -- Medium level functions ------------------------------------*/ + +static inline void gpio_bit12(unsigned char reg) +{ + // -- General Purpose I/O Bit 1.2 -- + // Bit 0, In/Out: 0 = Output, 1 = Input + // Bit 1, Polarity: 0 = No Invert, 1 = Invert + // Bit 2, Group Enable Intr.: 0 = Disable, 1 = Enable + // Bit 3/4, Function select: 00 = GPI/O, 01 = WDT, 10 = P17, + // 11 = Either Edge Triggered Intr. 2 + // Bit 5/6 (Reserved) + // Bit 7, Output Type: 0 = Push Pull Bit, 1 = Open Drain + write_io_cr(0xE2, reg); +} + +static inline void gpio_bit13(unsigned char reg) +{ + // -- General Purpose I/O Bit 1.3 -- + // Bit 0, In/Out: 0 = Output, 1 = Input + // Bit 1, Polarity: 0 = No Invert, 1 = Invert + // Bit 2, Group Enable Intr.: 0 = Disable, 1 = Enable + // Bit 3, Function select: 0 = GPI/O, 1 = LED + // Bit 4-6 (Reserved) + // Bit 7, Output Type: 0 = Push Pull Bit, 1 = Open Drain + write_io_cr(0xE3, reg); +} + +static inline void wdt_timer_units(unsigned char new_units) +{ + // -- Watchdog timer units -- + // Bit 0-6 (Reserved) + // Bit 7, WDT Time-out Value Units Select + // (0 = Minutes, 1 = Seconds) + write_io_cr(0xF1, new_units); +} + +static inline void wdt_timeout_value(unsigned char new_timeout) +{ + // -- Watchdog Timer Time-out Value -- + // Bit 0-7 Binary coded units (0=Disabled, 1..255) + write_io_cr(0xF2, new_timeout); +} + +static inline void wdt_timer_conf(unsigned char conf) +{ + // -- Watchdog timer configuration -- + // Bit 0 Joystick enable: 0* = No Reset, 1 = Reset WDT upon Gameport I/O + // Bit 1 Keyboard enable: 0* = No Reset, 1 = Reset WDT upon KBD Intr. + // Bit 2 Mouse enable: 0* = No Reset, 1 = Reset WDT upon Mouse Intr. + // Bit 3 Reset the timer + // (Wrong in SMsC documentation?
