I was wondering if the mechanism to patch the microcode for AMD k7 and later processors is the same as with the intel P6 series?

from what I understand, K7 and later do feature a microcode update feature but I have not been able to find any information on how to utilize it. I know with the pentiums the microcode is updated via the MSRs... no idea with AMD chips.

By chance, is it possible to read the trace-cache of the pentiums, i.e., the decoded x86 instructions (micro-instructions)? I am not well-versed in micro-architecture so please excuse me if I said something silly :)
