    TPM is basically never for your benefit. It’s becoming a requirement because Microsoft is going to one day say “you can only run apps installed from the Windows Store, because everything else is insecure” and lock down the software market. Valve knows this which is why they’re going so hard on the Steam Deck and Linux.

        I don’t know why I keep hearing of security measures to stop someone sleuthing into bootloaders.

        Am I the only person using Linux who isn’t James Bond?

          so you never caught a team of government officials in your living room brute forcing your bootloader at 4am as you got up to use the bathroom, huh. Lucky guy.

        This is why I keep my initrd tattooed as a barcode on my testicles.

          Kernel upgrades are very… Painful.

        TPM bad, put your secrets on a proper encryption peripheral, like a smartcard running javacardOS

        TPM will turn into cpu-bound DRM, the more you use it, the more this cancer will grow

            You are only seeing what TPM is now. Not what TPM will become when it become an entire encrypted computing processor capable of executing any code while inspection is impossible.

            Imagine denuvo running at ring level -1

    I always just kill my TPM chip. It’s so obvious tpm will be used in the future for application offline DRM. They will executed encrypted operations under the TPM veil and decompilers will become unusable.

        Level 1, turn off in bios

        Level 2, desolder from motherboard

        Level 3, remove cpu pins related to tpm

        Level 4, decap cpu, laser off tpm bus or blocks

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.
