Hello,

On x86 the persistent_clock() is backed by the
CMOS/EFI/kvm-wall/xen/vrtc clock (all via x86_platform.get_wallclock)
should be present and we'll initialize the time in timekeeping_init()
there.

Its only systems where there isn't a persistent_clock is where the RTC
layer and the HCTOSYS is helpful.

I'm a bit confused too. ;)

Doesn't this remove the users choice of RTC on x86 systems?

Why is there a difference made between the CMOS/EFI/... clocks and other RTCs?

And why is RTC_SYSTOHC now gone on x86?

Regards,

Alexander
