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 --- Reading git-diff-tree failed
