Struct rutabaga_gfx::rutabaga_gralloc::minigbm::MinigbmDevice

pub struct MinigbmDevice {
    minigbm_device: Arc<MinigbmDeviceInner>,
    last_buffer: Option<Arc<MinigbmBuffer>>,
}

A device capable of allocating MinigbmBuffer.

Fields

minigbm_device: Arc<MinigbmDeviceInner>

last_buffer: Option<Arc<MinigbmBuffer>>

Implementations

impl MinigbmDevice

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

Returns a new MinigbmDevice if there is a rendernode in /dev/dri/ that is accepted by the minigbm library.

Trait Implementations

impl Clone for MinigbmDevice

fn clone(&self) -> MinigbmDevice

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Gralloc for MinigbmDevice

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.
