drm/nve0: allow specification of channel engine type in abi16 call Previously, if either vram/gart handles were specified as ~0, the ioctl call would fail. In order to hack engine selection into the ioctl for kepler, we now define (fb_ctxdma_handle == ~0) to mean "engine mask is in tt_ctxdma_handle". This approach also allows new userspace to detect lack of support for non-PGRAPH channels on older kernels. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
