GpuVa

Struct GpuVa 

Source
pub struct GpuVa<T: DriverGpuVm> { /* private fields */ }
Expand description

Represents that a range of a GEM object is mapped in this GpuVm instance.

Does not assume that GEM lock is held.

§Invariants

  • This is a valid drm_gpuva object that is resident in a GpuVm<T> instance.
  • It is associated with a GpuVmBo<T>. Or in other words, it’s not an gpuvm->kernel_alloc_node and DRM_GPUVA_SPARSE is not set.
  • The associated GpuVmBo<T> is part of the GEM list.

Implementations§

Source§

impl<T: DriverGpuVm> GpuVa<T>

Source

pub fn project<'__pin>( self: Pin<&'__pin mut Self>, ) -> GpuVaProjection<'__pin, T>

Pin-projects all fields of Self.

These fields are structurally pinned:

  • inner
  • data

These fields are not structurally pinned:

Source§

impl<T: DriverGpuVm> GpuVa<T>

Source

pub unsafe fn from_raw<'a>(ptr: *mut drm_gpuva) -> &'a Self

Access this GpuVa from a raw pointer.

§Safety
  • For the duration of 'a, the pointer must reference a valid drm_gpuva associated with a GpuVm<T>.
  • It must be associated with a GpuVmBo<T>.
  • The associated GpuVmBo<T> is part of the GEM list.
Source

pub fn as_raw(&self) -> *mut drm_gpuva

Returns a raw pointer to underlying C value.

Source

pub fn addr(&self) -> u64

Returns the address of this mapping in the GPU virtual address space.

Source

pub fn length(&self) -> u64

Returns the length of this mapping.

Source

pub fn range(&self) -> Range<u64>

Returns addr..addr+length.

Source

pub fn gem_offset(&self) -> u64

Returns the offset within the GEM object.

Source

pub fn obj(&self) -> &T::Object

Returns the GEM object.

Source

pub fn vm_bo(&self) -> &GpuVmBo<T>

Returns the underlying GpuVmBo object that backs this GpuVa.
