---

Description:

Content:

Interfaces:

• PhysMemoryAllocator

Classes:

• DRMDumbAllocator - Private intance object for DRMDumbAllocator.
• DmaBufAllocator - Base class for allocators with dmabuf-backed memory
• FdAllocator - Base class for allocators with fd-backed memory

Enums:

• FdMemoryFlags - Various flags to control the operation of the fd backed memory.

Constants:

• public const string ALLOCATOR_DMABUF
• public const string ALLOCATOR_FD
• public const string CAPS_FEATURE_MEMORY_DMABUF
  Constant that defines the caps feature name for DMA buffer sharing.

Functions:

• public int dmabuf_memory_get_fd (Memory mem)
  Return the file descriptor associated with mem.
• public Memory drm_dumb_memory_export_dmabuf (Memory mem)
  Exports a DMABuf from the DRM Bumb buffer object.
• public uint32 drm_dumb_memory_get_handle (Memory mem)
  Return the DRM buffer object handle associated with mem.
• public int fd_memory_get_fd (Memory mem)
  Get the fd from mem.
• public bool is_dmabuf_memory (Memory mem)
  Check if mem is dmabuf memory.
• public bool is_drm_dumb_memory (Memory mem)
• public bool is_fd_memory (Memory mem)
  Check if mem is memory backed by an fd
• public bool is_phys_memory (Memory mem)
• public uintptr phys_memory_get_phys_addr (Memory mem)
