i had Qubes on 3 different Systems so far. All capable of HTT as lscpu announces and it being activated in the BIOS.
But lscpu also states, that i only have one thread per core on all machines.
Does someone have tips on how to troubleshoot this?
Part of the mitigation is to disable hyper-threading...
Note that BIOS settings allow in general to deactivate hyper-threading, and it’s a good idea to do it on all your machines (not only Qubes OS machines).
