[RFC PATCHv2 0/3] dma_buf import support for vgem
Hi, This is v2 of my proposal to add dma_buf import functions for vgem. Big changes from v1: - A device is required for dma_buf attach to work. The existing vgem driver intentionally does not use one as it provides a good way to test the DRM framework. This approach instead puts a dummy platform device in the existing drm_device->platformdev field and uses that for attaching. - Native vgem buffers can still be faulted in a page at a time without requiring the entire buffer be resident in memory. I'm still marking this as RFC as I haven't had a chance to finish a userspace test that can be integrated into igt. Feedback appreciated as always.
