Class EXTExternalMemoryDmaBuf


  • public final class EXTExternalMemoryDmaBuf
    extends java.lang.Object
    A dma_buf is a type of file descriptor, defined by the Linux kernel, that allows sharing memory across kernel device drivers and across processes. This extension enables applications to import a dma_buf as VkDeviceMemory; to export VkDeviceMemory as a dma_buf; and to create VkBuffer objects that can be bound to that memory.
