      cpuidle-haltpoll: do not set an owner to allow modunload · 472f2636
      Joao Martins authored
      cpuidle-haltpoll can be built as a module to allow optional late load.
      Given we are setting @owner to THIS_MODULE, cpuidle will attempt to grab a
      module reference every time a cpuidle_device is registered -- so
      essentially all online cpus get a reference.
      
      This prevents for the module to be unloaded later, which makes the
      module_exit callback entirely unused. Thus remove the @owner and allow
      module to be unloaded.

      cpuidle-haltpoll: return -ENODEV on modinit failure · 5cc59f59
      Joao Martins authored
      When a user loads cpuidle-haltpoll on a non KVM guest the module will
      successfully load, even though idle driver registration didn't take
      place.
      
      We should instead return -ENODEV signaling the user that the driver can't
      be loaded, like other error paths in haltpoll_init().  An example of such
      error paths is when we return -EBUSY when attempting to register an idle
      driver when it had one already (e.g. intel_idle loads at boot and then we
      attempt to insert module cpuidle-haltpoll).

      cpuidle-haltpoll: set haltpoll as preferred governor · 73214408
      Joao Martins authored
      Right now, guest current governors have the following ratings:
      
       * ladder            -> 10
       * teo               -> 19
       * menu              -> 20
       * haltpoll          -> 21
       * ladder + nohz=off -> 25
      
      haltpoll governor got introduced and it is now the default governor given
      its highest rating -- with ladder+nohz being the exception -- regardless of
      idle driver in the guest. An example of an undesirable case is x86 KVM
      guests with MWAIT which have intel_idle registered first, and consequently
      will have haltpoll be used as governor which would get limited to a poll
      state and state 1 and the other states wouldn't get used.
      
      To keep the previous defaults we decrease rating of governor to 9 (below
      current lowest rating) and thus rely on @governor switch on
      cpuidle_register_driver() to tie in haltpoll idle driver and governor
      together.

      cpuidle: allow governor switch on cpuidle_register_driver() · cb5d8c45
      Joao Martins authored
      The recently introduced haltpoll driver is largely only useful with
      haltpoll governor. To allow drivers to associate with a particular idle
      behaviour, add a @governor property to 'struct cpuidle_driver' and thus
      allow a cpuidle driver to switch to a *preferred* governor on idle driver
      registration. We save the previous governor, and when an idle driver is
      unregistered we switch back to that.
      
      The @governor can be overridden by cpuidle.governor= boot param or
      alternatively be ignored if the governor doesn't exist.

      cpuidle: teo: Allow tick to be stopped if PM QoS is used · cab09f3d
      Rafael J. Wysocki authored
      The TEO goveror prevents the scheduler tick from being stopped (unless
      stopped already) if there is a PM QoS latency constraint for the given
      CPU and the target residency of the deepest idle state matching that
      constraint is below the tick boundary.
      
      However, that is problematic if CPUs with PM QoS latency constraints
      are idle for long times, because it effectively causes the tick to
      run on them all the time which is wasteful.  [It is also confusing
      and questionable if they are full dynticks CPUs.]
      
      To address that issue, modify the TEO governor to carry out the
      entire search for the most suitable idle state (from the target
      residency perspective) even if a latency constraint is present,
      to allow it to determine the expected idle duration in all cases.
      
      Also, when using the last several measured idle duration values
      to refine the idle state selection, make it compare those values
      with the current expected idle duration value (instead of
      comparing them with the target residency of the idle state
      selected so far) which should prevent the tick from being
      retained when it makes sense to stop it sometimes (especially
      in the presence of PM QoS latency constraints).

      cpuidle: menu: Allow tick to be stopped if PM QoS is used · 32b91ca1
      Rafael J. Wysocki authored
      After commit 554c8aa8 ("sched: idle: Select idle state before
      stopping the tick") the menu governor prevents the scheduler tick from
      being stopped (unless stopped already) if there is a PM QoS latency
      constraint for the given CPU and the target residency of the deepest
      idle state matching that constraint is below the tick boundary.
      
      However, that is problematic if CPUs with PM QoS latency constraints
      are idle for long times, because it effectively causes the tick to
      run on them all the time which is wasteful.  [It is also confusing
      and questionable if they are full dynticks CPUs.]
      
      To address that issue, make the menu governor allow the tick to be
      stopped only if the idle duration predicted by it is beyond the tick
      boundary, except when the shallowest idle state is selected upfront
      and it is not a "polling" one.
      
      Fixes: 554c8aa8 ("sched: idle: Select idle state before stopping the tick")

      Linus Torvalds authored
      Pull libnvdimm fixes from Dan Williams:
       "A collection of locking and async operations fixes for v5.3-rc2. These
        had been soaking in a branch targeting the merge window, but missed
        due to a regression hunt. This fixed up version has otherwise been in
        -next this past week with no reported issues.
      
        In order to gain confidence in the locking changes the pull also
        includes a debug / instrumentation patch to enable lockdep coverage
        for libnvdimm subsystem operations that depend on the device_lock for
        exclusion. As mentioned in the changelog it is a hack, but it works
        and documents the locking expectations of the sub-system in a way that
        others can use lockdep to verify. The driver core touches got an ack
        from Greg.
      
        Summary:
      
         - Fix duplicate device_unregister() calls (multiple threads competing
           to do unregister work when scheduling device removal from a sysfs
           attribute of the self-same device).
      
         - Fix badblocks registration order bug. Ensure region badblocks are
           initialized in advance of namespace registration.
      
         - Fix a deadlock between the bus lock and probe operations.
      
         - Export device-core infrastructure to coordinate async operations
           via the device ->dead state.
      
         - Add device-core infrastructure to validate device_lock() usage with
           lockdep"
