The memory unit is bytes, so this was nowhere near enough, now it's set to 4GiB. VIRGLRENDERER_USE_EXTERNAL_BLOB is required fo blob mapping to work properly. Signed-off-by: Matej Hrica <mhrica@redhat.com>
…retrieval This patch enhances the `create_3d` method for VirglRenderer to fall back to virgl_renderer_resource_get_info_ext and virgl_renderer_get_fd_for_texture when export_blob and query both fail to return a DMABUF handle or 3D info. This ensures that resources created via create_3d still obtain valid handle and metadata when the primary export path is unavailable. This enables the downstream users(e.g vhost-device-gpu) to access the 3D info after `resource_create_3d()` and forward it correctly to the VHOST scanout handlers(e.g. via VHOST_USER_GPU_DMABUF_SCANOUT2).

Add support for a zero-copy dmabuf scanout of resources. If the dmabuf scanout is not supported we still fallback to the basic_framebuffer feature (CPU copy). Signed-off-by: Matej Hrica <mhrica@redhat.com>
