| |
IA-64 does not have a directly accessible real-time clock. As far as I know the only method to access the clock on this platform is to go through EFI (Extensible Firmware Interface, like a BIOS), which is handled by efirtc.c.
genrtc can be configured on for this platform but does not build (because there is no asm/rtc.h), and anyhow it is never likely to be useful. I suggest that it should be disabled in Kconfig, as rtc.c already is.
Perhaps other platforms that don't support it should be turned off too.
