Hi all, I think some of you might already noticed a nice paper: Microcode is an abstraction layer on top of the physical components of a CPU and present in most generalpurpose CPUs today. In addition to facilitate complex and vast instruction sets, it also provides an update mechanism that

Hi, Sorry for the delay.> CPU ID 0x8001: fc0 So your CPU is revision "DH" which is pre "F". > But I have also seen that CONFIG_K8_REV_F_SUPPORT is not set in .config nope this is for some other CPUs. If you look to coreboot/src/cpu/amd/model_fxx/powernow_acpi.c, your CPU 0xfc0 has an
