From 58b519f3e5e491d5a3e320dc525f58ac439bdde4 Mon Sep 17 00:00:00 2001 From: Wim Van Sebroeck Date: Sun, 21 May 2006 12:48:44 +0200 Subject: [WATCHDOG] add WDIOC_GETTIMELEFT ioctl Some watchdog drivers have the ability to report the remaining time before the system will reboot. With the WDIOC_GETTIMELEFT ioctl you can now read the time left before the watchdog would reboot your system. The following drivers support this new IOCTL: i8xx_tco.c, pcwd_pci.c and pcwd_usb.c .
