    • RE: Nehalem cpu power management

      @andSmv thanks for the reply
      The server is a home test, power consumption is more important than stability, so I'll try to recompile xen.I guess it will be enough to recompile only version 4.13.4 ?

      PS.: I just looked at the source code and I don't see that there is a switch to turn it off. I will modify mwait-idle.c to see if it works 😄

      PS2: Done :

      [09:50 home-xcp ~]# xenpm get-cpuidle-states 0
      Max possible C-state: C9
      
      cpu id               : 0
      total C-states       : 5
      idle time(ms)        : 134037
      C0                   : transition [                5351]
                             residency  [                6507 ms]
      C1                   : transition [                  13]
                             residency  [                  15 ms]
      C2                   : transition [                  71]
                             residency  [                 120 ms]
      C3                   : transition [                 701]

      cc6                  : [               63719 ms]
      
      

      The intel.c had to be modified to be correct. Let's see how stable it will be.
