1	Hello list,
2
3	I see "[ 0.003162] No NUMA configuration found" in dmesg. Does that mean I
4	should, or can, remove the NUMA settings from the kernel? This is a Ryzen M9
5	5900X machine.

7	I have this at the moment:
8
9	$ grep NUMA /usr/src/linux/.config
10	CONFIG_ARCH_SUPPORTS_NUMA_BALANCING=y
11	# CONFIG_NUMA_BALANCING is not set
12	CONFIG_NUMA=y
13	CONFIG_AMD_NUMA=y
14	CONFIG_X86_64_ACPI_NUMA=y
15	# CONFIG_NUMA_EMU is not set
16	CONFIG_USE_PERCPU_NUMA_NODE_ID=y
17	CONFIG_ACPI_NUMA=y
18	CONFIG_NUMA_KEEP_MEMINFO=y
