2 # RTC class/drivers configuration
11 depends on !S390 && !UML
14 Generic RTC class support. If you say yes here, you will
15 be allowed to plug one or more RTCs to your system. You will
16 probably want to enable one or more of the interfaces below.
21 bool "Set system time from RTC on startup and resume"
24 If you say yes here, the system time (wall clock) will be set using
25 the value read from a specified RTC device. This is useful to avoid
26 unnecessary fsck runs at boot time, and to network better.
28 config RTC_HCTOSYS_DEVICE
29 string "RTC used to set the system time"
30 depends on RTC_HCTOSYS
33 The RTC device that will be used to (re)initialize the system
34 clock, usually rtc0. Initialization is done when the system
35 starts up, and when it resumes from a low power state. This
36 device should record time in UTC, since the kernel won't do
39 The driver for this RTC device must be loaded before late_initcall
40 functions run, so it must usually be statically linked.
42 This clock should be battery-backed, so that it reads the correct
43 time when the system boots from a power-off state. Otherwise, your
44 system will need an external clock source (like an NTP server).
46 If the clock you specify here is not battery backed, it may still
47 be useful to reinitialize system time when resuming from system
48 sleep states. Do not specify an RTC here unless it stays powered
49 during all this system's supported sleep states.
52 bool "Set the RTC time based on NTP synchronization"
55 If you say yes here, the system time (wall clock) will be stored
56 in the RTC specified by RTC_HCTOSYS_DEVICE approximately every 11
57 minutes if userspace reports synchronized NTP status.
59 config RTC_SYSTOHC_DEVICE
60 string "RTC used to synchronize NTP adjustment"
61 depends on RTC_SYSTOHC
62 default RTC_HCTOSYS_DEVICE if RTC_HCTOSYS
65 The RTC device used for NTP synchronization. The main difference
66 between RTC_HCTOSYS_DEVICE and RTC_SYSTOHC_DEVICE is that this
67 one can sleep when setting time, because it runs in the workqueue
71 bool "RTC debug support"
73 Say yes here to enable debugging support in the RTC framework
74 and individual RTC drivers.
76 comment "RTC interfaces"
79 bool "/sys/class/rtc/rtcN (sysfs)"
83 Say yes here if you want to use your RTCs using sysfs interfaces,
84 /sys/class/rtc/rtc0 through /sys/.../rtcN.
89 bool "/proc/driver/rtc (procfs for rtcN)"
93 Say yes here if you want to use your system clock RTC through
94 the proc interface, /proc/driver/rtc.
95 Other RTCs will not be available through that API.
96 If there is no RTC for the system clock, then the first RTC(rtc0)
102 bool "/dev/rtcN (character devices)"
105 Say yes here if you want to use your RTCs using the /dev
106 interfaces, which "udev" sets up as /dev/rtc0 through
109 You may want to set up a symbolic link so one of these
110 can be accessed as /dev/rtc, which is a name
111 expected by "hwclock" and some other programs. Recent
112 versions of "udev" are known to set up the symlink for you.
116 config RTC_INTF_DEV_UIE_EMUL
117 bool "RTC UIE emulation on dev interface"
118 depends on RTC_INTF_DEV
120 Provides an emulation for RTC_UIE if the underlying rtc chip
121 driver does not expose RTC_UIE ioctls. Those requests generate
122 once-per-second update interrupts, used for synchronization.
124 The emulation code will read the time from the hardware
125 clock several times per second, please enable this option
126 only if you know that you really need it.
129 tristate "Test driver/device"
131 If you say yes here you get support for the
132 RTC test driver. It's a software RTC which can be
133 used to test the RTC subsystem APIs. It gets

135 You want this driver only if you are doing development
136 on the RTC subsystem. Please read the source code
