19 * /dev/rtc ... is the RTC provided by PC compatible systems,
35 Old PC/AT-Compatible driver: /dev/rtc
57 The interrupts are reported via /dev/rtc (major 10, minor 135, read only
62 /proc/driver/rtc if the /proc filesystem was enabled. The driver has
63 built in locking so that only one process is allowed to have the /dev/rtc
67 select(2) on /dev/rtc -- either will block/stop the user process until
75 typical 486-33 running a tight read loop on /dev/rtc will start to suffer
85 a different value to /proc/sys/dev/rtc/max-user-freq. Note that the
98 various ioctl(2) calls as listed in ./include/linux/rtc.h
105 (The original /dev/rtc driver was written by Paul Gortmaker.)
117 * /dev/rtcN ... much the same as the older /dev/rtc interface
119 * /sys/class/rtc/rtcN ... sysfs attributes support readonly
122 * /proc/driver/rtc ... the system clock RTC may expose itself
142 The sysfs interface under /sys/class/rtc/rtcN provides access to various
143 rtc attributes without requiring the use of ioctls. All dates and times
164 The ioctl() calls supported by /dev/rtc are also supported by the RTC class
194 Note that many of these ioctls are handled by the common rtc-dev interface.
