      powerpc/perf: Never program book3s PMCs with values >= 0x80000000 · f5602941
      Anton Blanchard authored
      
      
      We are seeing a lot of PMU warnings on POWER8:
      
          Can't find PMC that caused IRQ
      
      Looking closer, the active PMC is 0 at this point and we took a PMU
      exception on the transition from negative to 0. Some versions of POWER8
      have an issue where they edge detect and not level detect PMC overflows.
      
      A number of places program the PMC with (0x80000000 - period_left),
      where period_left can be negative. We can either fix all of these or
      just ensure that period_left is always >= 1.
      
      This patch takes the second option.

      Fix the problem by disabling RELOCATABLE for COMPILE_TEST builds instead.
      While this is less than perfect, it avoids substantial code changes

      powerpc/perf: Clear MMCR2 when enabling PMU · b50a6c58
      Joel Stanley authored
      On POWER8 when switching to a KVM guest we set bits in MMCR2 to freeze
      the PMU counters. Aside from on boot they are then never reset,
      resulting in stuck perf counters for any user in the guest or host.
      
      We now set MMCR2 to 0 whenever enabling the PMU, which provides a sane
      state for perf to use the PMU counters under either the guest or the
      host.
      
      This was manifesting as a bug with ppc64_cpu --frequency:
      
          $ sudo ppc64_cpu --frequency
          WARNING: couldn't run on cpu 0
          WARNING: couldn't run on cpu 8
            ...
          WARNING: couldn't run on cpu 144
          WARNING: couldn't run on cpu 152
          min:    18446744073.710 GHz (cpu -1)
          max:    0.000 GHz (cpu -1)
          avg:    0.000 GHz
      
      The command uses a perf counter to measure CPU cycles over a fixed
      amount of time, in order to approximate the frequency of the machine.
      The counters were returning zero once a guest was started, regardless of
      weather it was still running or had been shut down.
      
      By dumping the value of MMCR2, it was observed that once a guest is
      running MMCR2 is set to 1s - which stops counters from running:
      
          $ sudo sh -c 'echo p > /proc/sysrq-trigger'
          CPU: 0 PMU registers, ppmu = POWER8 n_counters = 6
          PMC1:  5b635e38 PMC2: 00000000 PMC3: 00000000 PMC4: 00000000
          PMC5:  1bf5a646 PMC6: 5793d378 PMC7: deadbeef PMC8: deadbeef
          MMCR0: 0000000080000000 MMCR1: 000000001e000000 MMCRA: 0000040000000000
          MMCR2: fffffffffffffc00 EBBHR: 0000000000000000
          EBBRR: 0000000000000000 BESCR: 0000000000000000
          SIAR:  00000000000a51cc SDAR:  c00000000fc40000 SIER:  0000000001000000
      
      This is done unconditionally in book3s_hv_interrupts.S upon entering the
      guest, and the original value is only save/restored if the host has
      indicated it was using the PMU. This is okay, however the user of the
      PMU needs to ensure that it is in a defined state when it starts using
      it.

      powerpc/kvm: Remove redundant save of SIER AND MMCR2 · f73128f4
      Joel Stanley authored
      These two registers are already saved in the block above. Aside from
      being unnecessary, by the time we get down to the second save location
      r8 no longer contains MMCR2, so we are clobbering the saved value with
      PMC5.
      
      MMCR2 primarily consists of counter freeze bits. So restoring the value
      of PMC5 into MMCR2 will most likely have the effect of freezing
      counters.

      powerpc/powernv: Check for IRQHAPPENED before sleeping · c733cf83
      Preeti U Murthy authored
      Commit 8d6f7c5a
      
      : "powerpc/powernv: Make it possible to skip the IRQHAPPENED
      check in power7_nap()" added code that prevents cpus from checking for
      pending interrupts just before entering sleep state, which is wrong. These
      interrupts are delivered during the soft irq disabled state of the cpu.
      
      A cpu cannot enter any idle state with pending interrupts because they will
      never be serviced until the next time the cpu is woken up by some other
      interrupt. Its only then that the pending interrupts are replayed. This can result
      in device timeouts or warnings about this cpu being stuck.
      
      This patch fixes ths issue by ensuring that cpus check for pending interrupts
      just before entering any idle state as long as they are not in the path of split
      core operations.

      Jan Beulich authored
      
      
      Relying on static functions used just once to get inlined (and
      subsequently have dead code paths eliminated) is wrong: Compilers are
      free to decide whether they do this, regardless of optimization level.
      With this not happening for vdso_addr() (observed with gcc 4.1.x), an
      unresolved reference to align_vdso_addr() causes the build to fail.
      
      [ hpa: vdso_addr() is never actually used on x86-32, as calculate_addr
        in map_vdso() is always false.  It ought to be possible to clean
        this up further, but this fixes the immediate problem. ]

      If there are error flags in the aux transaction return
      -EIO rather than -EBUSY.  -EIO restarts the whole transaction
      while -EBUSY jus retries.  Fixes problematic aux transfers.

      dm mpath: fix IO hang due to logic bug in multipath_busy · 7a7a3b45
      Jun'ichi Nomura authored
      Commit e8099177
      
       ("dm mpath: push back requests instead of queueing")
      modified multipath_busy() to return true if !pg_ready().  pg_ready()
      checks the current state of the multipath device and may return false
      even if a new IO is needed to change the state.
      
      Bart Van Assche reported that he had multipath IO lockup when he was
      performing cable pull tests.  Analysis showed that the multipath
      device had a single path group with both paths active, but that the
      path group itself was not active.  During the multipath device state
      transitions 'queue_io' got set but nothing could clear it.  Clearing
      'queue_io' only happens in __choose_pgpath(), but it won't be called
      if multipath_busy() returns true due to pg_ready() returning false
      when 'queue_io' is set.
      
      As such the !pg_ready() check in multipath_busy() is wrong because new
      IO will not be sent to multipath target and the multipath state change
      won't happen.  That results in multipath IO lockup.
      
      The intent of multipath_busy() is to avoid unnecessary cycles of
      dequeue + request_fn + requeue if it is known that the multipath
      device will requeue.
      
      Such "busy" situations would be:
        - path group is being activated
        - there is no path and the multipath is setup to requeue if no path
      
      Fix multipath_busy() to return "busy" early only for these specific
      situations.

      dm io: fix a race condition in the wake up code for sync_io · 10f1d5d1
      Joe Thornber authored
      
      
      There's a race condition between the atomic_dec_and_test(&io->count)
      in dec_count() and the waking of the sync_io() thread.  If the thread
      is spuriously woken immediately after the decrement it may exit,
      making the on stack io struct invalid, yet the dec_count could still
      be using it.
      
      Fix this race by using a completion in sync_io() and dec_count().

      dm: allocate a special workqueue for deferred device removal · acfe0ad7
      Mikulas Patocka authored
      The commit 2c140a24
      
       ("dm: allow remove to be deferred") introduced a
      deferred removal feature for the device mapper.  When this feature is
      used (by passing a flag DM_DEFERRED_REMOVE to DM_DEV_REMOVE_CMD ioctl)
      and the user tries to remove a device that is currently in use, the
      device will be removed automatically in the future when the last user
      closes it.
      
      Device mapper used the system workqueue to perform deferred removals.
      However, some targets (dm-raid1, dm-mpath, dm-stripe) flush work items
      scheduled for the system workqueue from their destructor.  If the
      destructor itself is called from the system workqueue during deferred
      removal, it introduces a possible deadlock - the workqueue tries to flush
      itself.
      
      Fix this possible deadlock by introducing a new workqueue for deferred
      removals.  We allocate just one workqueue for all dm targets.  The
      ability of dm targets to process IOs isn't dependent on deferred removal
      of unused targets, so a deadlock due to shared workqueue isn't possible.
      
      Also, cleanup local_init() to eliminate potential for returning success
      on failure.
