AMD PSP (Platform Security Processor) on Ideapad L340

2021-04-26, 11:20 AM

Do we have an information on what the PSP does, in particular on the Ideapad L340?  I have found only an oblique reference to managing the boot process, and wonder whether it might resist changing the boot drive.

Hello John Kaufmann,

 

PSP basically counterpart of the Intel Management Engine which AMD maybe able to provide more specific information.

 

What do you have in mind for configuring your boot system?

Thanks for your reply.  In another thread, I consider whether failure of a cloned drive to boot might be related to some PSP function. Beyond the specific problem of failure to boot, I thought it best to start a new thread on the basic issue of:

  1. what the PSP does;
  2. the function and identity of the PSP key;
  3. the effect of disabling the PSP or clearing the PSP key.

 

It is, at least, weird and disappointing that we don't have clear definition on those basic questions.  For example, one might try disabling the PSP or clearing the PSP key, but it would be nice to know first (a) what effects those actions would have, (b) how to read the PSP key before clearing it, (c) how to reestablish the key.
