(was [coreboot] Coreboot Purism BIOS is free? open?) Regarding the "AMD pre-PSP" devices, I have a very naive question : are some of them still in production or none of them? (i.e all one can buy nowadays are only "pre-owned" devices with a life expectancy far less than that of a new one..) What about the opteron line? Are they still in production? Sorry for hijacking the thread and thank you for answers.. Florentin

Sadly the ARM processor also have the ME-like backdoor (called "TrustZone).
Some have. Some not. Some have it and it's owner-controllable. It's not about the ISA and some optional architectural feature, it's about the chip you buy.
And even MIPS is going this road soon (check out the "MIPS OmniShield" news).
Could it be the requirement of US Government - for all the consumer CPU to have backdoors ? My last hopes are on POWER 9 and RISC V now ; meanwhile sticking to the AMD pre-PSP tech
Forget it. RISC-V already has SMM like tech in the architecture. But that doesn't matter as long as you can buy chip's that are owner con- trollable. Such features make it harder to keep everything secure but they don't force the silicon vendor to lock you out (as long as you don't ask to be able to watch Netflix in high resolution or something like that).
