    PCI: add OBFF enable/disable support · 48a92a81
    Jesse Barnes 提交于
    OBFF (optimized buffer flush/fill), where supported, can help improve
    energy efficiency by giving devices information about when interrupts
    and other activity will have a reduced power impact.  It requires
    support from both the device and system (i.e. not only does the device
    need to respond to OBFF messages, but the platform must be capable of
    generating and routing them to the end point).
