VKMS currently does not handle dumb data, and as a consequence, it does not provide mechanisms for handling gem. This commit adds the necessary support for gem object/handler and the dumb functions. Changes since V1: Daniel Vetter: - Add dumb buffer support to the same patchset Changes since V2: Haneen: - Add missing gem_free_object_unlocked callback to fix the warning "Memory manager not clean during takedown" Signed-off-by: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/70b7becc91c6a323dbc15cb5fc912cbdfe4ef7d9.1531359228.git.rodrigosiqueiramelo@gmail.com
