      cpuidle/powerpc: Fix snooze state problem in the cpuidle design on pseries. · 83dac594
      Deepthi Dharwar 提交于
      Earlier without cpuidle framework on pseries, the native arch
      idle routine comprised of both snooze and nap
      states.  smt_snooze_delay variable was used to delay
      the idle process entry to deeper idle state like  nap.
      With the coming of cpuidle, this arch specific idle was replaced
      by two different idle routines, one for supporting snooze and other
      for nap. This enabled addition of more
      low level idle states on pseries in the future.
      
      On adopting the generic cpuidle framework for POWER systems,
      the decision of which idle state to choose from,  given a predicted
      idle time is taken by the menu governor based on
      target_residency and  exit_latency of the idle states.
      target_residency is the minimum time to be resident in that idle state.
      Exit_latency is time taken to exit out of idle state.
      Deeper the idle state, both the target residency and exit latency
      would be higher.
      
      In the current design, smt_snooze_delay is used as target_residency
      for the  snooze state which is incorrect, as it is not the
      minimum but the maximum duration to be in snooze state.
      This would  result in the governor in taking bad decision,
      as presently target_residency of nap < target_residency of snooze
      inspite of nap being deeper idle state.
      
      This patch aims to fix this problem by replacing the smt_snooze_delay loop
      in snooze state, with the need_resched()  as the governor is aware of
      entry and exit of various idle transitions based on which
      next idle time prediction.
      
      The governor is intelligent enough to determine the idle state the needs to
      be transitioned to and maintains a whole of heuristics including
      io load, previous idle states predictions etc for the same, based on
      which idle state entry decision is taken.
      
      With this fix, of setting target_residency of snooze to 0
      					     nap to smt_snooze_delay
      if the predicted idle time is less
      than smt_snooze_delay (target_residency of nap)
      value governor would pick snooze state, else nap. This adhers to the
      previous native idle design.

      cpuidle/powerpc: Fix smt_snooze_delay functionality. · 8ea959a1
      Deepthi Dharwar 提交于
      smt_snooze_delay was designed to  delay idle loop's nap entry
      in the native idle code before it got  ported over to use as part of
      the cpuidle framework.
      
      A -ve value  assigned to smt_snooze_delay should result in
      busy looping, in other words disabling the entry to nap state.
      
      	- https://lists.ozlabs.org/pipermail/linuxppc-dev/2010-May/082450.html
      
      This particular functionality can be achieved currently by
      echo 1 > /sys/devices/system/cpu/cpu*/state1/disable
      but it is broken when one assigns -ve value to  the smt_snooze_delay
      variable either via sysfs entry or ppc64_cpu util.
      
      This patch aims to fix this, by disabling nap state when smt_snooze_delay
      variable is set to -ve value.

      Deepthi Dharwar 提交于
      Remove the redundant target residency initialisation in pseries_cpuidle_driver_init().
      This is currently over-writing the residency time updated as part of the static
      table, resulting in  all the idle states having the same target
      residency of 100us which is incorrect. This may result in the menu governor making
      wrong state decisions.

        (2) Make arch/tile's ucontext.h file use (1) and remove the header-y
            line from the kernel internal side of things.
      
        (3) Remove some now-empty conditional bits from include/linux/Kbuild.
            The contents got moved to the UAPI side of things along with new
            conditionals.
      
        (4) Deal with now-empty files:
      
           (a) Empty Kbuild files under include/ get removed.
      
           (b) Empty Kbuild files under arch/ get comments to hold them as
               they are likely to end up with generic-y or genhdr-y lines.
               Deleting them appears to work if we want to go that route.
      
           (c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the
               patch program from deleting that, and made the arches with
               empty kvm_para.h uapi files use that instead of having their
               own files.
      
           (d) Put comments into four other empty uapi/ headers to prevent the
               patch program from deleting them.
      
        A question: Is this the right way to deal with the now-empty Kbuild
        files?
      
        The ones under include/ are unlikely to be used - even for generated
        files, I think - so getting rid of them is probably okay.  Once all
        the bits are in, we can probably remove all the Kbuild files under
        include/ that aren't also under include/uapi/.
      
        The ones under arch/ are more of an issue because of the potential for
        generic-y and genhdr-y."
