Hi all, I'm working on GPU virtualization on the Renesas rcar-du embedded platform. My setup consists of - a primary Linux instance which controls all DUs (display units) and the GPU (3D engine) and - secondary Linux instances which have virtual access to the GPU and to selected DUs. I try to find out what's necessary to allow the secondary Linux instance(s) access to selected DUs (which are controlled by the primary Linux instance). To my understanding I need a kernel module which is able to forward certain ioctls, at least - DRM_IOCTL_MODE_GETRESOURCES - DRM_IOCTL_MODE_GETCONNECTOR - DRM_IOCTL_MODE_GETENCODER - DRM_IOCTL_MODE_CREATE_DUMB - DRM_IOCTL_MODE_MAP_DUMB - DRM_IOCTL_MODE_GETCRTC - DRM_IOCTL_MODE_SETCRTC - DRM_IOCTL_MODE_ADDFB - DRM_IOCTL_MODE_PAGE_FLIP maybe more. At least I see 'mpv' in opengl/drm mode doing these syscalls during display setup. As the board contains 4 DUs and 4 connectors (VGA, HDMI0, HDMI1, LVDS) I try to assign one of the HDMI connectors exclusively to a secondary Linux instance. I wonder if there are related projects and if my list of ioctls to be emulated is complete. Thanks, Frank _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
