  • d05089443   cpuidle: cpuidle-cps: add MIPS CPS cpuidle driver ... Browse Code »

    This patch adds a cpuidle driver for systems based around the MIPS
    Coherent Processing System (CPS) architecture. It supports four idle
    states:

    - The standard MIPS wait instruction.

    - The non-coherent wait, clock gated & power gated states exposed by
    the recently added pm-cps layer.

    The pm-cps layer is used to enter all the deep idle states. Since cores
    in the clock or power gated states cannot service interrupts, the
    gic_send_ipi_single function is modified to send a power up command for
    the appropriate core to the CPC in cases where the target CPU has marked
    itself potentially incoherent.
