      iommu/arm-smmu: Restore naming of driver parameter prefix · ab362fff
      Will Deacon authored
      Extending the Arm SMMU driver to allow for modular builds changed
      KBUILD_MODNAME to be "arm_smmu_mod" so that a single module could be
      built from the multiple existing object files without the need to rename
      any source files.
      
      This inadvertently changed the name of the driver parameters, which may
      lead to runtime issues if bootloaders are relying on the old names for
      correctness (e.g. "arm-smmu.disable_bypass=0").
      
      Although MODULE_PARAM_PREFIX can be overridden to restore the old naming
      for builtin parameters, only the new name is matched by modprobe and so
      loading the driver as a module would cause parameters specified on the
      kernel command line to be ignored. Instead, rename "arm_smmu_mod" to
      "arm_smmu". Whilst it's a bit of a bodge, this allows us to create a
      single module without renaming any files and makes use of the fact that
      underscores and hyphens can be used interchangeably in parameter names.

      iommu/qcom: Fix bogus detach logic · faf305c5
      Robin Murphy authored
      Currently, the implementation of qcom_iommu_domain_free() is guaranteed
      to do one of two things: WARN() and leak everything, or dereference NULL
      and crash. That alone is terrible, but in fact the whole idea of trying
      to track the liveness of a domain via the qcom_domain->iommu pointer as
      a sanity check is full of fundamentally flawed assumptions. Make things
      robust and actually functional by not trying to be quite so clever.

      iommu/amd: Disable IOMMU on Stoney Ridge systems · 3dfee47b
      Kai-Heng Feng authored
      Serious screen flickering when Stoney Ridge outputs to a 4K monitor.
      
      Use identity-mapping and PCI ATS doesn't help this issue.
      
      According to Alex Deucher, IOMMU isn't enabled on Windows, so let's do
      the same here to avoid screen flickering on 4K monitor.

        Debug options like DEBUG_TEST_DRIVER_REMOVE, KASAN and DEBUG_KMEMLEAK
        unearthed issues with the lifespan of memory allocated by the EDAC
        memory controller descriptor due to misdesigned memory freeing, done
        partially by the EDAC core *and* the driver core, which is problematic
        to say the least.
      
        These two are minimal fixes to take care of stable - a proper rework
        is following which cleans up that mess properly"
