The article argues that one should trust microcode updates at least as much as the original microcode. Okay. But why would you trust microcode? It's closed source software running at the base layer of privilege and you have very little idea what it's doing or whether it's correct.
- ip26 4y agoYou could say that about the entire CPU. Original microcode should be trusted equal to the rest of the chip.
- bo1024 4y agoYes, agree.
- detaro 4y agoThe same logic applies to everything about the CPU though. That parts of it features are implemented in microcode instead of dedicated circuitry makes 0 difference for trust or not, so singling out microcode when not talking about updates is kinda odd.
- olliej 4y agoOk, very simple question: why do you trust the closed source vhdl/verilog/whatever but not the closed source microcode?
