How to disable retpoline?












0














I need to disable retpoline for a use case. I tried adding noretpoline to the boot parameter but it doesn't seem to work.
The output after adding noretpoline param:



$ cat /sys/devices/system/cpu/vulnerabilities/spectre_v2
Mitigation: Full generic retpoline, STIBP: disabled, RSB filling


Kernel: 4.18.0-58.el8.x86_64
