AMD Immune to MDS Vulnerabilities

Is there an option to turn off all mitigations? A public hoster is different to my local build server where security is not an issue and only performance counts.

Linux 5.2 is supposedly introducing a flag that does exactly what you want.

Part of the mitigations is a microcode update, which may be embedded in your computers firmware (BIOS/UEFI). You could of course _not_ update your server firmware, but it could make you vulnerable to all kinds of security issues.

I believe there are some Linux kernel parameters to tune things.
