Booted system with "-smp 8,sockets=2,clusters=2,cores=1,threads=2" and
got what I wanted:
cpus {
#size-cells = <0x00>;
#address-cells = <0x02>;
cpu-map {
socket0 {
cluster0 {
core0 {
thread0 {
cpu = <0x8007>;
};
thread1 {
cpu = <0x8006>;
};
};
};
cluster1 {
core0 {
thread0 {
cpu = <0x8005>;
};
thread1 {
cpu = <0x8004>;
};
};
};
};
socket1 {
cluster0 {
core0 {
thread0 {
cpu = <0x8003>;
};
thread1 {
cpu = <0x8002>;
};
};
};
cluster1 {
core0 {
thread0 {
cpu = <0x8001>;
};
thread1 {
cpu = <0x8000>;
};
};
};
};
};
cpu@0 {
phandle = <0x8007>;
reg = <0x00 0x00>;
};
cpu@1 {
phandle = <0x8006>;
reg = <0x00 0x01>;
};
cpu@2 {
phandle = <0x8005>;
reg = <0x00 0x02>;
};
cpu@3 {
phandle = <0x8004>;
reg = <0x00 0x03>;
};
cpu@4 {
phandle = <0x8003>;
reg = <0x00 0x04>;
};
cpu@5 {
phandle = <0x8002>;
reg = <0x00 0x05>;
};
cpu@6 {
phandle = <0x8001>;
reg = <0x00 0x06>;
};
cpu@7 {
phandle = <0x8000>;
reg = <0x00 0x07>;
};
};
