      vfio: Tie IOMMU group reference to vfio group · 4a68810d
      Alex Williamson authored
      Move the iommu_group reference from the device to the vfio_group.
      This ensures that the iommu_group persists as long as the vfio_group
      remains.  This can be important if all of the device from an
      iommu_group are removed, but we still have an outstanding vfio_group
      reference; we can still walk the empty list of devices.

      vfio: Add device tracking during unbind · 60720a0f
      Alex Williamson authored
      There's a small window between the vfio bus driver calling
      vfio_del_group_dev() and the device being completely unbound where
      the vfio group appears to be non-viable.  This creates a race for
      users like QEMU/KVM where the kvm-vfio module tries to get an
      external reference to the group in order to match and release an
      existing reference, while the device is potentially being removed
      from the vfio bus driver.  If the group is momentarily non-viable,
      kvm-vfio may not be able to release the group reference until VM
      shutdown, making the group unusable until that point.
      Bridge the gap between device removal from the group and completion
      of the driver unbind by tracking it in a list.  The device is added
      to the list before the bus driver reference is released and removed
      using the existing unbind notifier.

      vfio/type1: Add conditional rescheduling · c5e66887
      Alex Williamson authored
      IOMMU operations can be expensive and it's not very difficult for a
      user to give us a lot of work to do for a map or unmap operation.
      Killing a large VM will vfio assigned devices can result in soft
      lockups and IOMMU tracing shows that we can easily spend 80% of our
      time with need-resched set.  A sprinkling of conf_resched() calls
      after map and unmap calls has a very tiny affect on performance
      while resulting in traces with <1% of calls overflowing into needs-

      vfio/type1: Chunk contiguous reserved/invalid page mappings · babbf176
      Alex Williamson authored
      We currently map invalid and reserved pages, such as often occur from
      mapping MMIO regions of a VM through the IOMMU, using single pages.
      There's really no reason we can't instead follow the methodology we
      use for normal pages and find the largest possible physically
      contiguous chunk for mapping.  The only difference is that we don't
      do locked memory accounting for these since they're not back by RAM.
      In most applications this will be a very minor improvement, but when
      graphics and GPGPU devices are in play, MMIO BARs become non-trivial.

      vfio/type1: DMA unmap chunking · 6fe1010d
      Alex Williamson authored
      When unmapping DMA entries we try to rely on the IOMMU API behavior
      that allows the IOMMU to unmap a larger area than requested, up to
      the size of the original mapping.  This works great when the IOMMU
      supports superpages *and* they're in use.  Otherwise, each PAGE_SIZE
      increment is unmapped separately, resulting in poor performance.
      Instead we can use the IOVA-to-physical-address translation provided
      by the IOMMU API and unmap using the largest contiguous physical
      memory chunk available, which is also how vfio/type1 would have
      mapped the region.  For a synthetic 1TB guest VM mapping and shutdown
      test on Intel VT-d (2M IOMMU pagesize support), this achieves about
      a 30% overall improvement mapping standard 4K pages, regardless of
      IOMMU superpage enabling, and about a 40% improvement mapping 2M
      hugetlbfs pages when IOMMU superpages are not available.  Hugetlbfs
      with IOMMU superpages enabled is effectively unchanged.
      Unfortunately the same algorithm does not work well on IOMMUs with
      fine-grained superpages, like AMD-Vi, costing about 25% extra since
      the IOMMU will automatically unmap any power-of-two contiguous
      mapping we've provided it.  We add a routine and a domain flag to
      detect this feature, leaving AMD-Vi unaffected by this unmap

      sched: don't cause task state changes in nested sleep debugging · 00845eb9
      Linus Torvalds authored
      Commit 8eb23b9f
       ("sched: Debug nested sleeps") added code to report
      on nested sleep conditions, which we generally want to avoid because the
      inner sleeping operation can re-set the thread state to TASK_RUNNING,
      but that will then cause the outer sleep loop not actually sleep when it
      calls schedule.
      However, that's actually valid traditional behavior, with the inner
      sleep being some fairly rare case (like taking a sleeping lock that
      normally doesn't actually need to sleep).
      And the debug code would actually change the state of the task to
      TASK_RUNNING internally, which makes that kind of traditional and
      working code not work at all, because now the nested sleep doesn't just
      sometimes cause the outer one to not block, but will cause it to happen
      every time.
      In particular, it will cause the cardbus kernel daemon (pccardd) to
      basically busy-loop doing scheduling, converting a laptop into a heater,
      as reported by Bruno Prémont.  But there may be other legacy uses of
      that nested sleep model in other drivers that are also likely to never
      get converted to the new model.
      This fixes both cases:
       - don't set TASK_RUNNING when the nested condition happens (note: even
         if WARN_ONCE() only _warns_ once, the return value isn't whether the
         warning happened, but whether the condition for the warning was true.
         So despite the warning only happening once, the "if (WARN_ON(..))"
         would trigger for every nested sleep.
       - in the cases where we knowingly disable the warning by using
         "sched_annotate_sleep()", don't change the task state (that is used
         for all core scheduling decisions), instead use '->task_state_change'
         that is used for the debugging decision itself.
      (Credit for the second part of the fix goes to Oleg Nesterov: "Can't we
      avoid this subtle change in behaviour DEBUG_ATOMIC_SLEEP adds?" with the
      suggested change to use 'task_state_change' as part of the test)

      arm/arm64: KVM: Use kernel mapping to perform invalidation on page fault · 0d3e4d4f
      Marc Zyngier authored
      When handling a fault in stage-2, we need to resync I$ and D$, just
      to be sure we don't leave any old cache line behind.
      That's very good, except that we do so using the *user* address.
      Under heavy load (swapping like crazy), we may end up in a situation
      where the page gets mapped in stage-2 while being unmapped from
      userspace by another CPU.
      At that point, the DC/IC instructions can generate a fault, which
      we handle with kvm->mmu_lock held. The box quickly deadlocks, user
      is unhappy.
      Instead, perform this invalidation through the kernel mapping,
      which is guaranteed to be present. The box is much happier, and so
      am I.

      arm/arm64: KVM: Use set/way op trapping to track the state of the caches · 3c1e7165
      Marc Zyngier authored
      Trying to emulate the behaviour of set/way cache ops is fairly
      pointless, as there are too many ways we can end-up missing stuff.
      Also, there is some system caches out there that simply ignore
      set/way operations.
      So instead of trying to implement them, let's convert it to VA ops,
      and use them as a way to re-enable the trapping of VM ops. That way,
      we can detect the point when the MMU/caches are turned off, and do
      a full VM flush (which is what the guest was trying to do anyway).
      This allows a 32bit zImage to boot on the APM thingy, and will
      probably help bootloaders in general.

      vm: make stack guard page errors return VM_FAULT_SIGSEGV rather than SIGBUS · 9c145c56
      Linus Torvalds authored
      The stack guard page error case has long incorrectly caused a SIGBUS
      rather than a SIGSEGV, but nobody actually noticed until commit
       ("mm: propagate error from stack expansion even for guard
      page") because that error case was never actually triggered in any
      normal situations.
      Now that we actually report the error, people noticed the wrong signal
      that resulted.  So far, only the test suite of libsigsegv seems to have
      actually cared, but there are real applications that use libsigsegv, so
      let's not wait for any of those to break.

      vm: add VM_FAULT_SIGSEGV handling support · 33692f27
      Linus Torvalds authored
      The core VM already knows about VM_FAULT_SIGBUS, but cannot return a
      "you should SIGSEGV" error, because the SIGSEGV case was generally
      handled by the caller - usually the architecture fault handler.
      That results in lots of duplication - all the architecture fault
      handlers end up doing very similar "look up vma, check permissions, do
      retries etc" - but it generally works.  However, there are cases where
      the VM actually wants to SIGSEGV, and applications _expect_ SIGSEGV.
      In particular, when accessing the stack guard page, libsigsegv expects a
      SIGSEGV.  And it usually got one, because the stack growth is handled by
      that duplicated architecture fault handler.
      However, when the generic VM layer started propagating the error return
      from the stack expansion in commit fee7e49d
       ("mm: propagate error
      from stack expansion even for guard page"), that now exposed the
      existing VM_FAULT_SIGBUS result to user space.  And user space really
      expected SIGSEGV, not SIGBUS.
      To fix that case, we need to add a VM_FAULT_SIGSEGV, and teach all those
      duplicate architecture fault handlers about it.  They all already have
      the code to handle SIGSEGV, so it's about just tying that new return
      value to the existing code, but it's all a bit annoying.
      This is the mindless minimal patch to do this.  A more extensive patch
      would be to try to gather up the mostly shared fault handling logic into
      one generic helper routine, and long-term we really should do that
      Just from this patch, you can generally see that most architectures just
      copied (directly or indirectly) the old x86 way of doing things, but in
      the meantime that original x86 model has been improved to hold the VM
      semaphore for shorter times etc and to handle VM_FAULT_RETRY and other
      "newer" things, so it would be a good idea to bring all those
      improvements to the generic case and teach other architectures about
      them too.

      ARM: shmobile: r8a7790: Instantiate GIC from C board code in legacy builds · 77cf5166
      Magnus Damm authored
      As of commit 9a1091ef
       ("irqchip: gic: Support hierarchy irq
      domain."), the Lager legacy board support is known to be broken.
      The IRQ numbers of the GIC are now virtual, and no longer match the
      hardcoded hardware IRQ numbers in the legacy platform board code.
      To fix this issue specific to non-multiplatform r8a7790 and Lager:
       1) Instantiate the GIC from platform board code and also
       2) Skip over the DT arch timer as well as
       3) Force delay setup based on DT CPU frequency
      With these 3 fixes in place interrupts on Lager are now unbroken.
      Partially based on legacy GIC fix by Geert Uytterhoeven, thanks to
      him for the initial work.
