Hi,
still not 100% sure, whether I configured the kernel correctlu:
Running an AMD RYZEN 5 3600...
lscpu displays:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I set (beside other things) these kernel configurations:
Processor type and features --->
[*] Symmetric multi-processing support
[*] AMD ACPI2Platform devices support
[*] Supported processor vendors --->
[*] Support AMD processors
[*] SMT (Hyperthreading) scheduler support
[*] Multi-core scheduler support
Preemption Model (Preemptible Kernel (Low-Latency Desktop)) --->
[*] Machine Check / overheating reporting
[*] AMD MCE features
Performance monitoring --->
<*> AMD Processor Power Reporting Mechanism
[*] AMD microcode loading support
Power management and ACPI options --->
CPU Frequency scaling --->
<*> AMD Opteron/Athlon64 PowerNow!
<*> AMD frequency sensitivity feedback powersave bias
Device Drivers --->
[*] IOMMU Hardware Support --->
[*] AMD IOMMU support
<*> AMD IOMMU Version 2 driver
htop shows six cores.
Does my CPU hyperthread?
Cheers
