Is there any computer that's open source and libra from the ground up? Including boot firmware, power management and tuning in the CPU etc? If you're truly concerned about privacy and security you can't do any x86 or Arm based computer because there are no computer that will expose all the nooks and crannies for hardening or validation. But there are such computers. Raptor Computing https://www.raptorcs.com/ [raptorcs.com] are offering several POWER based models where every software part is open source, and even much of t
Cool! I have never even considered this. Thanks for pointing me to a very scary part of Computer Science:) However.. Regarding OpenPOWER systems, since the all levels of software is open, and the ISA is open, you can (given an insane level of CS proficiency) probably (or at least much more likely compared the competition) write software to validate that what you are actually running is what you intend to be running. And have a fairly high degree of probability to find out if the silicon's doping is compromised.
And given an insane amount of money, you can purchase a license of the CPUs from IBM and fab your own, even change them if you like (and can). A Chinese company (Suzhou C*Core Technology Co or China-Core for short) did this with POWER8 and replaced security macros in the CPU since they wanted Chinese IP there instead of American. The resulting POWER8 processor is called CP1, and is functionally identical to IBM's.

Enjoy googling "dopant-level hardware trojans".
Yes, those exist in the wild now.
Don't ask me how I know.
