      PM / OPP: Support updating performance state of device's power domain · 009acd19
      Viresh Kumar 提交于
      The genpd framework now provides an API to request device's power
      domain to update its performance state.  Use that interface from the
      OPP core for devices whose power domains support performance states.
      
      Note that this commit doesn't add any mechanism by which performance
      states are made available to the OPP core. That would be done by a
      later commit.
      
      Note that the current implementation is restricted to the case where
      the device doesn't have separate regulators for itself. We shouldn't
      over engineer the code before we have real use case for them. We can
      always come back and add more code to support such cases later on.

      PM / OPP: add missing of_node_put() for of_get_cpu_node() · 9867999f
      Sudeep Holla 提交于
      Commit 76279291 (PM / OPP: Fix get sharing CPUs when hotplug
      is used) moved away from using cpu_dev->of_node because of some
      limitations.
      
      However, commit 7467c9d9 (of: return of_get_cpu_node from
      of_cpu_device_node_get if CPUs are not registered) added support to
      fall back to of_get_cpu_node() if called if CPUs are not registered
      yet.
      
      Add the missing of_node_put() for the CPU device nodes. Also go back
      to using of_cpu_device_node_get() in dev_pm_opp_of_get_sharing_cpus()
      to avoid scanning the device tree again.

      PM / Domains: Add support to select performance-state of domains · 42f6284a
      Viresh Kumar 提交于
      Some platforms have the capability to configure the performance state of
      PM domains. This patch enhances the genpd core to support such
      platforms.
      
      The performance levels (within the genpd core) are identified by
      positive integer values, a lower value represents lower performance
      state.
      
      This patch adds a new genpd API, which is called by user drivers (like
      OPP framework):
      
      - int dev_pm_genpd_set_performance_state(struct device *dev,
      					 unsigned int state);
      
        This updates the performance state constraint of the device on its PM
        domain. On success, the genpd will have its performance state set to a
        value which is >= "state" passed to this routine. The genpd core calls
        the genpd->set_performance_state() callback, if implemented,
        else -ENODEV is returned to the caller.
      
      The PM domain drivers need to implement the following callback if they
      want to support performance states.
      
      - int (*set_performance_state)(struct generic_pm_domain *genpd,
      			       unsigned int state);
      
        This is called internally by the genpd core on several occasions. The
        genpd core passes the genpd pointer and the aggregate of the
        performance states of the devices supported by that genpd to this
        callback. This callback must update the performance state of the genpd
        (in a platform dependent way).
      
      The power domains can avoid supplying above callback, if they don't
      support setting performance-states.
      
      Currently we aren't propagating performance state changes of a subdomain
      to its masters as we don't have hardware that needs it right now. Over
      that, the performance states of subdomain and its masters may not have
      one-to-one mapping and would require additional information. We can get
      back to this once we have hardware that needs it.

      Pull watchddog clean-up and fixes from Thomas Gleixner:
       "The watchdog (hard/softlockup detector) code is pretty much broken in
        its current state. The patch series addresses this by removing all
        duct tape and refactoring it into a workable state.
      
        The reasons why I ask for inclusion that late in the cycle are:
      
         1) The code causes lockdep splats vs. hotplug locking which get
            reported over and over. Unfortunately there is no easy fix.
      
         2) The risk of breakage is minimal because it's already broken
      
         3) As 4.14 is a long term stable kernel, I prefer to have working
            watchdog code in that and the lockdep issues resolved. I wouldn't
            ask you to pull if 4.14 wouldn't be a LTS kernel or if the
            solution would be easy to backport.
      
         4) The series was around before the merge window opened, but then got
            delayed due to the UP failure caused by the for_each_cpu()
            surprise which we discussed recently.
      
        Changes vs. V1:
      
         - Addressed your review points
      
         - Addressed the warning in the powerpc code which was discovered late
      
         - Changed two function names which made sense up to a certain point
           in the series. Now they match what they do in the end.
      
         - Fixed a 'unused variable' warning, which got not detected by the
           intel robot. I triggered it when trying all possible related config
           combinations manually. Randconfig testing seems not random enough.
      
        The changes have been tested by and reviewed by Don Zickus and tested
        and acked by Micheal Ellerman for powerpc"

      arm64: Ensure fpsimd support is ready before userspace is active · ae2e972d
      Suzuki K Poulose 提交于
      We register the pm/hotplug callbacks for FPSIMD as late_initcall,
      which happens after the userspace is active (from initramfs via
      populate_rootfs, a rootfs_initcall). Make sure we are ready even
      before the userspace could potentially use it, by promoting to
      a core_initcall.

      arm64: Ensure the instruction emulation is ready for userspace · c0d8832e
      Suzuki K Poulose 提交于
      We trap and emulate some instructions (e.g, mrs, deprecated instructions)
      for the userspace. However the handlers for these are registered as
      late_initcalls and the userspace could be up and running from the initramfs
      by that time (with populate_rootfs, which is a rootfs_initcall()). This
      could cause problems for the early applications ending up in failure
      like :
      
      [   11.152061] modprobe[93]: undefined instruction: pc=0000ffff8ca48ff4
      
      This patch promotes the specific calls to core_initcalls, which are
      guaranteed to be completed before we hit userspace.

      powerpc/powernv: Increase memory block size to 1GB on radix · 53ecde0b
      Anton Blanchard 提交于
      Memory hot unplug on PowerNV radix hosts is broken. Our memory block
      size is 256MB but since we map the linear region with very large
      pages, each pte we tear down maps 1GB.
      
      A hot unplug of one 256MB memory block results in 768MB of memory
      getting unintentionally unmapped. At this point we are likely to oops.
      
      Fix this by increasing our memory block size to 1GB on PowerNV radix
      hosts.

      dm raid: fix incorrect status output at the end of a "recover" process · 41dcf197
      Jonathan Brassow 提交于
      There are three important fields that indicate the overall health and
      status of an array: dev_health, sync_ratio, and sync_action.  They tell
      us the condition of the devices in the array, and the degree to which
      the array is synchronized.
      
      This commit fixes a condition that is reported incorrectly.  When a member
      of the array is being rebuilt or a new device is added, the "recover"
      process is used to synchronize it with the rest of the array.  When the
      process is complete, but the sync thread hasn't yet been reaped, it is
      possible for the state of MD to be:
       mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ]
       curr_resync_completed = <max dev size> (but not MaxSector)
       and all rdevs to be In_sync.
      This causes the 'array_in_sync' output parameter that is passed to
      rs_get_progress() to be computed incorrectly and reported as 'false' --
      or not in-sync.  This in turn causes the dev_health status characters to
      be reported as all 'a', rather than the proper 'A'.
      
      This can cause erroneous output for several seconds at a time when tools
      will want to be checking the condition due to events that are raised at
      the end of a sync process.  Fix this by properly calculating the
      'array_in_sync' return parameter in rs_get_progress().
      
      Also, remove an unnecessary intermediate 'recovery_cp' variable in
      rs_get_progress().
