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.

Good news for AMD Linux users - fTPM RNG will soon be disabled (www.phoronix.com)

For those out of the loop, some AMD users have been suffering from stuttering issues caused by the AMD fTPM random number generator. A firmware/BIOS update appears to fix the issue for some users, but not others, leading to more bug reports being sent in. Last week, Linus Torvalds said "let's just disable the stupid fTPM hwrnd thing", and, as of today the Linux kernel has gone ahead and blanket disabled RNG use for all current AMD fTPMs.

You can also solve this problem by disabling the TPM in the BIOS settings, assuming your motherboard has such a setting. No TPM, no problem.

Yeah. I think I disabled it the day I built my system.

This is the way. Besides these stuttering issues, the TPM is owner-disobedient (there is no way for the owner to extract keys stored in it) and an unnecessary attack surface (which, if breached, gives the attacker unfettered, persistent, and irrevocable access to the entire machine).
