Hi Hanjun,
I have just compiled a kernel with your patches and it starts to boot then locks up. From the kernel log it looks like the CPUs are being recognised from your patches.
ACPI: Added _OSI(Module Device) ACPI: Added _OSI(Processor Device) ACPI: Added _OSI(3.0 _SCP Extensions) ACPI: Added _OSI(Processor Aggregator Device) ACPI: EC: EC description table is found, configuring boot EC ACPI: Interpreter enabled ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [_S1_] (20130117/hwxface-568) ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [_S2_] (20130117/hwxface-568) ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [_S3_] (20130117/hwxface-568) ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [_S5_] (20130117/hwxface-568) ACPI: (supports S0) ACPI: Using GIC for interrupt routing
After this line kernel locks up.
Complete boot log is here.
Hi Graeme,
Thanks a lot for the test, I will find out what's happening here.
Could you pls give me a boot log without my patch? In this way I can compare the log and solve this problem more quickly.
Thanks Hanjun
Hi Hanjun,
Boot log before your patches is here.

This patch set is about to implement the CPU topology support for ACPI processor driver, which includes the os lever code and the ASL code. both are compiled ok, but not tested on the hardware;
For the ACPI processor driver, when cpu is hot added, arch_fix_phys_package_id(), acpi_map_lsapic() and arch_register_cpu() are arch specific; When cpu is hot removed, arch_unregister_cpu()/acpi_unmap_lsapic() is arch specific.
arch_register_cpu() will register the logic cpu on sysfs, create topology information interface, and create online/offline interface for cpu hotplug. unregister is doing the reverse.
For the ASL part, I implement the proto code for the CPU topology with one physical CPU and two cpu cores.
