  • zx::result<PhysVmo> GetTestPhysVmo (size_t size)

    Create and return a physical VMO from the reserved regions of RAM. |size|

    indicates the desired size of the VMO, or 0 to fetch the entire reserved

    region of RAM, whatever its size might be.

  • void VmoCheck (const zx::vmo & vmo, uint32_t expected, uint64_t offset)

    Defined at line 34 of file ../../zircon/system/utest/core/vmo/helpers.h

  • void InitPageTaggedVmo (uint32_t page_count, zx::vmo * vmo)

    Creates a vmo with |page_count| pages and writes (page_index + 1) to each page.

    Defined at line 42 of file ../../zircon/system/utest/core/vmo/helpers.h

  • template <typename Predicate>
    bool PollVmoInfoUntil (const zx::vmo & vmo, Predicate && predicate)

    Repeatedly poll VMO until |predicate| returns true or an error occurs.

    Returns true on success, false on error.

    |Predicate| is a function that accepts |const zx_info_vmo_t

    &

    | and returns |bool|.

  • size_t VmoNumChildren (const zx::vmo & vmo)

    Defined at line 70 of file ../../zircon/system/utest/core/vmo/helpers.h

  • bool PollVmoNumChildren (const zx::vmo & vmo, size_t expected_num_children)

    Repeatedly poll |vmo| until the |expected_num_children| is observed.

    Returns true on success, false on error.

  • zx::bti CreateNamedBti (const zx::iommu & fake_iommu, uint32_t options, uint64_t bti_id, const char * name)

  • size_t VmoPopulatedFractionalBytes (const zx::vmo & vmo)

    Defined at line 101 of file ../../zircon/system/utest/core/vmo/helpers.h

  • bool PollVmoPopulatedBytes (const zx::vmo & vmo, size_t expected_populated_bytes)

    Repeatedly poll |vmo| until the |expected_populated_bytes| is observed.

    Returns true on success, false on error.

  • deferred_action<(lambda at ../../zircon/system/utest/core/vmo/helpers.h:137:21)> CreateDeferredBtiCheck (const zx::bti & bti)

    Create a fit::defer which will check a BTI to make certain that it has no

    pinned or quarantined pages when it goes out of scope, and fail the test if

    it does.

  • template <size_t PageCountuint8_t FillByte = 0>
    std::span<const uint8_t> TestFillPages ()

    For the given number of pages and fill byte value, return a

    permanently-usable, read-only buffer. The first call for each page count

    and byte value will allocate and fill the buffer, and subsequent calls will

    just reuse the same one. All these buffers live forever once they are used,

    but there is a limited number of PageCount, FillByte combinations used in

    each test and the page counts are not huge.
