There is a "Memory Node Interleaving" section in BIOS and two options
that I can choose :
SMP or NUMA
=> no disabled option
Either one will get "No NUMA configuration found" in dmesg
And I don't see any ACPI SRAT information during boot.
the boot command is "swiotlb=65536 ro root=LABEL=/ quiet numa=acpi"
Is it correct? (I have no right to change it to debug mode to see if
anything wrong)
