The Linux kernel configuration item CONFIG_PCIEASPM
has multiple definitions:
drivers/pci/pcie/Kconfig
The configuration item CONFIG_PCIEASPM:
CONFIG_EXPERT
This enables OS control over PCI Express ASPM (Active State Power Management) and Clock Power Management. ASPM supports state L0/L0s/L1.
ASPM is initially set up by the firmware. With this option enabled, Linux can modify this state in order to disable ASPM on known-bad hardware or configurations and enable it when known-safe.
ASPM can be disabled or enabled at runtime via /sys/module/pcie_aspm/parameters/policy
When in doubt, say Y.
drivers/pci/pcie/Kconfig
The configuration item CONFIG_PCIEASPM:
CONFIG_PCI && CONFIG_EXPERIMENTAL && CONFIG_PCIEPORTBUS
This enables PCI Express ASPM (Active State Power Management) and Clock Power Management. ASPM supports state L0/L0s/L1.
When in doubt, say N.
