[Xen-devel] [PATCH] Tools: add online/offline hotplug user interfaces

["Ke, Liping" <liping.ke@xxxxxxxxx>]

Hi, all

 

This patch is for exporting cpu on/offline and memory on/offline hotplug interfaces,

so that users can do those (memory/cpu) hotplug actions with following command line:

 

usage: xen-hptool <command> [args]

    xen-hptool command list:\n\n

    cpu-online    <cpuid>    online CPU <cpuid>

    cpu-offline   <cpuid>    offline CPU <cpuid>

    mem-online    <mfn>      online MEMORY <mfn>

    mem-offline   <mfn>      offline MEMORY <mfn>

    mem-status    <mfn>      query Memory status<mfn>

 

When mcelog do user-level predictive recovery actions, this tool interface might be called by mcelog

recovery action scripts(mem page online/offline, eg). That’s why I want to push this tool firstly.

 

Thanks& Regards,

criping
