Michael Brown	05719804b9	[rng] Add RTC-based entropy source ... The RTC-based entropy source uses the nanosecond-scale CPU TSC to measure the time between two 1kHz interrupts generated by the CMOS RTC. In a physical machine these clocks are driven from independent crystals, resulting in some observable clock drift. In a virtual machine, the CMOS RTC is typically emulated using host-OS constructions such as SIGALRM. Signed-off-by: Michael Brown <mcb30@ipxe.org>	2012-02-28 11:18:48 +00:00
