Implementations

impl SystemGralloc

fn new() -> Self

pub fn init() -> RutabagaResult<Box<dyn Gralloc>>

Returns a new SystemGralloc instance.

Trait Implementations

impl Gralloc for SystemGralloc

fn supports_external_gpu_memory(&self) -> bool

This function must return true if the implementation can:

fn supports_dmabuf(&self) -> bool

This function must return true the implementation can {export to}/{import from} a Linux dma-buf. This often used for sharing with the scanout engine or multimedia subsystems.

fn get_image_memory_requirements( &mut self, info: ImageAllocationInfo ) -> RutabagaResult<ImageMemoryRequirements>

Implementations must return the resource layout, compression, and caching properties of an allocation request.

fn allocate_memory( &mut self, reqs: ImageMemoryRequirements ) -> RutabagaResult<RutabagaHandle>

Implementations must allocate memory given the requirements and return a RutabagaHandle upon success.

fn import_and_map( &mut self, _handle: RutabagaHandle, _vulkan_info: VulkanInfo, _size: u64 ) -> RutabagaResult<Box<dyn MappedRegion>>

Implementations must import the given handle and return a mapping, suitable for use with KVM and other hypervisors. This is optional and only works with the Vulkano backend.
