[$] Is it time for open processors?

Tuesday January 9, 2018. 03:32 PM , from LWN.net
The disclosure of the Meltdown and Spectre
vulnerabilities has brought a
new level of attention to the security bugs that can lurk at the hardware
level. Massive amounts of work have gone into improving the (still poor)
security of our software, but all of that is in vain if the hardware gives
away the game. The CPUs that we run in our systems are highly proprietary
and have been shown to contain unpleasant surprises (the Intel management
engine, for example). It is thus natural to wonder whether it is time to
make a move to open-source hardware, much like we have done with our
software. Such a move may well be possible, and it would certainly offer
some benefits, but it would be no panacea.
