      "message": "PCI: PCIE ASPM support\n\nPCI Express ASPM defines a protocol for PCI Express components in the D0\nstate to reduce Link power by placing their Links into a low power state\nand instructing the other end of the Link to do likewise. This\ncapability allows hardware-autonomous, dynamic Link power reduction\nbeyond what is achievable by software-only controlled power management.\nHowever, The device should be configured by software appropriately.\nEnabling ASPM will save power, but will introduce device latency.\n\nThis patch adds ASPM support in Linux. It introduces a global policy for\nASPM, a sysfs file /sys/module/pcie_aspm/parameters/policy can control\nit. The interface can be used as a boot option too. Currently we have\nbelow setting:\n        -default, BIOS default setting\n        -powersave, highest power saving mode, enable all available ASPM\nstate\nand clock power management\n        -performance, highest performance, disable ASPM and clock power\nmanagement\nBy default, the \u0027default\u0027 policy is used currently.\n\nIn my test, power difference between powersave mode and performance mode\nis about 1.3w in a system with 3 PCIE links.\n\nSigned-off-by: Shaohua Li \u003cshaohua.li@intel.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n"
