I have a Dell R740 with the latest BIOS. I am swapping them with R730s. Both are running ESXi v6.5U2h.
I noticed my R730s had the warning about the the L1 fault and so I set this to True.
VMkernel.Boot.hyperthreadingMitigation
My R740s never gave the CVE warning. I set the mitigation setting anyway and rebooted. However, it still had 72 Logical CPUs. This is a 36core box.
My R730s went from 72Logical CPUs to 36 after the fix.
Is the BIOS on my R740 not susceptical and thus the setting wont take?
