So if the shared object is lmem, then it needs to have the smem as second placement option. Currently kms_prime sharing the dumb buffer between the devices. But dumb buffer can't have the placements and resides at lmem for the dgfx. Hence to meet the i915 expectation for dgfx, we create the BO using the gem_create with smem as second placement option. v2: Used gem_mmap__device_coherent for mmaped ptr (Ashutosh) v3: dumb buffer ioctls are used for non i915 drivers Signed-off-by: Ramalingam C Reviewed-by: Ashutosh Dixit Reviewed-by: Michael J.
