Public Methods

::fidl::Result< ::fuchsia_hardware_goldfish::ControlDevice::CreateColorBuffer2> CreateColorBuffer2 (::fidl::Request< ::fuchsia_hardware_goldfish::ControlDevice::CreateColorBuffer2> request)

Create shared color buffer. Color buffer is automatically freed when

all references to `vmo` have been closed. Fails if VMO is not

associated with goldfish heap memory.

Arguments

Refer to `CreateColorBuffer2Params` for input arguments.

Return value

`res`: `ZX_ERR_ALREADY_EXISTS` if a buffer or color buffer has

already been created for this VMO.

`ZX_ERR_INVALID_ARGS` if arguments are invalid.

(see `CreateColorBuffer2Params`)

Otherwise returns `ZX_OK`.

`hw_address_page_offset`: memory page offset of the buffer's

hardware-mapped memory. For color buffers with HOST_VISIBLE

memory property bits, this value is a non-negative

integer in [0, 4095]. For non-HOST_VISIBLE memory or

failed allocation, this value is negative.

::fidl::Result< ::fuchsia_hardware_goldfish::ControlDevice::CreateBuffer2> CreateBuffer2 (::fidl::Request< ::fuchsia_hardware_goldfish::ControlDevice::CreateBuffer2> request)

Create shared data buffer. Buffer is automatically freed when

all references to `vmo` have been closed. Fails if VMO is not

associated with goldfish heap memory.

Arguments

Refer to `CreateBuffer2Params` for input arguments.

Return value

Error:

- `ZX_ERR_ALREADY_EXISTS` if a buffer or color buffer has

already been created for this VMO.

- `ZX_ERR_INVALID_ARGS` if arguments are invalid.

(see `CreateBuffer2Params`)

`hw_address_page_offset`:

Memory page offset of the buffer's hardware-mapped memory.

For buffers with HOST_VISIBLE memory property bits, this

value is a non-negative integer in [0, 4095]. For

non-HOST_VISIBLE memory, this value is negative.

::fidl::Result< ::fuchsia_hardware_goldfish::ControlDevice::GetBufferHandle> GetBufferHandle (::fidl::Request< ::fuchsia_hardware_goldfish::ControlDevice::GetBufferHandle> request)

Get a buffer handle for VMO and the type of the handle.

Fails if VMO is not associated with neither a color buffer nor a buffer.

Deprecated. Use `GetBufferHandleInfo()` instead.

::fidl::Result< ::fuchsia_hardware_goldfish::ControlDevice::GetBufferHandleInfo> GetBufferHandleInfo (::fidl::Request< ::fuchsia_hardware_goldfish::ControlDevice::GetBufferHandleInfo> request)

Get the info of buffer handle from a given VMO.

Return value

Error:

- `ZX_ERR_INVALID_ARGS` if given `vmo` is invalid.

- `ZX_ERR_NOT_FOUND` if `vmo` is not associated with any created

goldfish Buffer or ColorBuffer.

`info`: a BufferHandleInfo object containing the buffer id, type

and memory information.

::fidl::Result< ::fuchsia_hardware_goldfish::ControlDevice::CreateSyncFence> CreateSyncFence (::fidl::Request< ::fuchsia_hardware_goldfish::ControlDevice::CreateSyncFence> request)

Create a sync fence on goldfish control device. Client pass half of an

eventpair to this method, and `event` will signal its peer when all the

graphics work already queued on the EGL display context associated with

the control device when it is created has finished.

Errors:

- ZX_ERR_INTERNAL if device fail to create the fence or fail to

trigger the wait.
