Lenovo vendor locking Ryzen CPUs with AMD PSB
The problem is the AMD PSB functionality in itself. It should be considered malware like the Intel managament engine and thus refused by users. It's a second processor that runs a proprietary firmware signed by the vendor (that the user cannot modify or substitute entirely with a FLOSS alternative) that vendors can use do harm to the user.The AMD PSB can also be used to lock down a processor to enforce secure boot and thus don't let you run an unsigned operating system, i.e. no longer allowing you to run Linux on your machine that comes out of the factory with Windows preinstalled. That would be a very very bad thing.Unfortunately both for Intel and AMD you don't have choices these days. I'm hoping someone develops a processor based on the RISCV architecture (a free architecture that doesn't include that shit) to be used in a computer entirely under the control of the user (hardware and software) and not the corporation that makes it.
