From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

"Maybe use it for the boot-time 'gather entropy from different sources,' but clearly it should not be used at runtime."

Good idea. Ask it during boot/insmod for some hardware-random bits to seed Linux's usual software-only CSPRNG, then just use that.

And even that might not be a great idea. I wouldn't be surprised if the fTPM RNG is subtly not-entirely-random, at some alphabet agency's behest. I remember there being a controversy over rdrand for this reason…
