How to Build tuned Profiles for Dynamic Linux Kernel Mitigations dynamic mitigation functionality was created by AMD engineer David Kaplan, linked here is an article discussing it The recent introduction of "Dynamic Mitigations" for the Linux kernel provides a powerful new capability: the ability to enable or disable CPU security mitigations at runtime without a reboot. This is managed by writing to a special file at /sys/devices/system/cpu/mitigations .
