The Power10 issue isn't just memory training. There's a programmable processor in the memory interface that runs a signed blob.
That's a much more serious problem -- potentially even worse than the Intel ME since the ME can't possibly intercept every single memory access without the user noticing the slowdown.
- pabs3 5y agoIs POWER10 usable *at all* without that blob? Does the programmable processor itself enforce that signature? Is there a way to modify the keyring for that verification?
- octoberfranklin 5y ago> Is POWER10 usable at all without that blob? No. You might be able to use the on-die cache as RAM (most bootloaders do this), but that's less than 128MB. For the amount that these things cost nobody is going to want to use them with that little memory.
