/dev/alarm is necessary. It comes from a kernel patch called "android alarm". you have to patch it to regular kernel on your own. Without it, AlarmManagerService will have trouble to setup alarm.
RTC is rarely referred directly in android. however, SystemServer will read current time using gettiemofday. our kernel gives the value from RTC intial value. if it is 0, or (other uninitialized value), it's possible to crash AlarmManagerService later. thanks, --lx On Thu, Sep 8, 2011 at 11:48 PM, extrapedestrian <extra.pedestr...@gmail.com > wrote: > Im porting Froyo to mips board, and I have trouble building alarm > driver. > I added source to kernel, it builds and I have driver log, but I don't > have device. > device node is not created: /dev/alarm > I also don't have /dev/rtc and I think this might be causing problem. > When does 'rtc_alarm_add_device' gets to be called? > > thanks, > Petar > > -- > unsubscribe: android-porting+unsubscr...@googlegroups.com > website: http://groups.google.com/group/android-porting > -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
