This automatically enables PCI Express Port Bus support. Users can
choose Native Hot-Plug support, Advanced Error Reporting support,
Power Management Event support and Virtual Channel support to run
on PCI Express Ports (Root or Switch).

depends on HOTPLUG_PCI && PCIEPORTBUS
help
Say Y here if you have a motherboard that supports PCI Express Native
Hotplug
To compile this driver as a module, choose M here: the
module will be called pciehp.
When in doubt, say N.

# PCI Express ASPM
#
config PCIEASPM
bool "PCI Express ASPM control" if EXPERT
depends on PCI && PCIEPORTBUS
default y
help
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.
config PCIEASPM_DEBUG
bool "Debug PCI Express ASPM"
depends on PCIEASPM
default n
help
This enables PCI Express ASPM debug support. It will add per-device
interface to control ASPM.
config PCIE_PME
