menu "DMABUF options" config SYNC_FILE bool "Explicit Synchronization Framework" default n select ANON_INODES select DMA_SHARED_BUFFER ---help--- The Sync File Framework adds explicit syncronization via userspace. It enables send/receive 'struct dma_fence' objects to/from userspace via Sync File fds for synchronization between drivers via userspace components. It has been ported from Android. The first and main user for this is graphics in which a fence is associated with a buffer. When a job is submitted to the GPU a fence is attached to the buffer and is transferred via userspace, using Sync Files fds, to the DRM driver for example. More details at Documentation/sync_file.txt. config SW_SYNC bool "Sync File Validation Framework" default n depends on SYNC_FILE depends on DEBUG_FS ---help--- A sync object driver that uses a 32bit counter to coordinate synchronization. Useful when there is no hardware primitive backing the synchronization. WARNING: improper use of this can result in deadlocking kernel drivers from userspace. Intended for test and debug only. config UDMABUF bool "userspace dmabuf misc driver" default n depends on DMA_SHARED_BUFFER depends on MEMFD_CREATE || COMPILE_TEST help A driver to let userspace turn memfd regions into dma-bufs. Qemu can use this to create host dmabufs for guest framebuffers. endmenu
