drm_gem_shmem_get_sg_table is meant to implement obj->funcs->get_sg_table, for prime exporting. The one we want is drm_gem_shmem_get_pages_sgt, which also handles imported dma-buf, not just native objects. v2: Rebase, this stuff moved around in commit 2f2aa13724d56829d910b2fa8e80c502d388f106 Author: Gerd...

Yep. Intentional, but I think I

...dressing. You are describing the details, but I'm missing the big picture ... So, virtualization aside, how do buffers work in wayland? As far I know it goes like this: (a) software rendering: client allocates shared memory buffer, renders into it, then passes a file handle for that shmem block together with some meta data (size, format, ...) to the wayland server. (b) gpu rendering: client opens a render node, allocates a buffer, asks the cpu to renders into it, exports the buffer as dma-buf (DRM_IOCTL_PRIME_HANDLE_TO_FD), passes this to the wayland server...
