AMD Begins Plumbing APCI C4 Support in the Linux Kernel for Power Savings

• jeffbee 1y ago
  It would be nice to know what this actually does, to which CPUs, installed in what platform. There is only tenuous correspondence between ACPI C-states and the energy saving features of CPUs, and Intel started diverging from ACPI definitions around the time of Haswell, so a direct comparison is difficult.

  s/APCI/ACPI/. How embarrassing for them.

    Nope. That's AMD's Power Clamping Infrastructure.
