• zx::result<fdf::MmioBuffer> PDevMakeMmioBufferWeak (PDev::MmioInfo & pdev_mmio, uint32_t cache_policy)

  This helper is marked weak because it is sometimes necessary to provide a

  test-only version that allows for MMIO fakes or mocks to reach the driver under test.

  For example say you have a fake Protocol device that needs to smuggle a fake MMIO:

  class FakePDev {

  .....

  zx::result

  <MmioInfo

  > PDevGetMmio(uint32_t index) {

  MmioInfo out_mmio = {};

  out_mmio.offset = reinterpret_cast

  <size

  _t>(this);

  return zx::ok(out_mmio);

  }

  .....

  };

  The actual implementation expects a real {size, offset, VMO} and therefore it will

  fail. But works if a replacement PDevMakeMmioBufferWeak in the test is provided:

  zx::result

  <fdf

  ::MmioBuffer> PDevMakeMmioBufferWeak(const MmioInfo

  &

  pdev_mmio) {

  auto* test_harness = reinterpret_cast

  <FakePDev

  *>(pdev_mmio.offset);

  return zx::ok(test_harness->fake_mmio());

  }

  Note that if you are using `//sdk/lib/driver/fake-platform-device/cpp`, it provides an

  implementation of this functionality for you. Drivers must set the `mmios` field in

  `FakePDev::Config`.
