[bios] Add bin-x86_64-pcbios build platform

2016-02-16T19:32:32+00:00

Move most arch/i386 files to arch/x86, and adjust the contents of the Makefiles and the include/bits/*.h headers to reflect the new locations. This patch makes no substantive code changes, as can be seen using a rename-aware diff (e.g. "git show -M5"). This patch does not make the pcbios platform functional for x86_64; it merely allows it to compile without errors. Signed-off-by: Michael Brown

[rng] Add RTC-based entropy source

2012-02-28T11:18:48+00:00

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

[rng] Add ANS X9.82 Approved Source of Entropy Input

2012-02-21T12:42:38+00:00

ANS X9.82 specifies several Approved Sources of Entropy Input (SEI). One such SEI uses an entropy source as the Source of Entropy Input, condensing each entropy source output after each GetEntropy call. This can be implemented relatively cheaply in iPXE and avoids the need to allocate potentially very large buffers. (Note that the terms "entropy source" and "Source of Entropy Input" are not synonyms within the context of ANS X9.82.) Use the iPXE API mechanism to allow entropy sources to be selected at compilation time. Signed-off-by: Michael Brown
