Jonas Ådahl	f8daa6bc70	cogl/dma-buf: Add mmap/munmap helpers ... Avoids dealing directly with mmap() and munmap(). https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1237	2020-05-26 13:54:28 +00:00
Jonas Ådahl	5b07ccd0a7	cogl/dma-buf: Add API to synchronize reading ... Used before and after accessing DMA buffer content using mmap(). https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1237	2020-05-26 13:54:28 +00:00
Jonas Ådahl	4434a17d08	cogl/dma-buf-handle: Pass more metadata to handle constructor ... Could be useful would one want to mmap the dmabuf and deal with its content manually in CPU space. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1237	2020-05-26 13:54:27 +00:00
Georges Basile Stavracas Neto	3881c1f952	cogl/context: Add cogl_renderer_create_dma_buf() and family ... This is a winsys-specific API that allows exporting a DMA buffer fd. The CoglDmaBufHandle structure allows passing the ownership of the DMA buffer to whoever is using it, so the winsys doesn't need to manually track it. https://gitlab.gnome.org/GNOME/mutter/merge_requests/1086	2020-02-28 14:54:48 -03:00
