 *    - g->ops.gr.init.wait_idle.
 *    - g->ops.gr.falcon.ctrl_ctxsw.
 * -  Set default golden image size.
 * -  Allocate and bind channel and tsg.
 * -  Start BVEC testing for variable class_num.
 *    class_num is tested for range in common.class. In common.gr, stub out
 *    the common.class HALs to perform independent range testing. Before
 *    stubbing, save the valid initialization values for common.class HALs.
 * -  Call g->ops.gr.setup.alloc_obj_ctx with input class_num at boundary
 *    values - min boundary(0), max boundary(U32_MAX) and once with value
 *    in valid range. g->ops.gr.setup.alloc_obj_ctx value should return
 *    0 as all class_num values are valid from common.gr perspective.
 *    End BVEC testing for variable class_num by restoring the stubbed
 *    common.class HALs.
 * -  Start BVEC testing for variable flags.
 * -  Call g->ops.gr.setup.alloc_obj_ctx with input variable flags at boundary
 *    values - min boundary(0), max boundary(U32_MAX) and once with value
 *    in valid range. g->ops.gr.setup.alloc_obj_ctx value should return
 *    0 as all flags values are valid from common.gr perspective.
 *    End BVEC testing for variable flags.
 * -  Call g->ops.gr.setup.alloc_obj_ctx with valid class_num -
 *    VOLTA_DMA_COPY_A and VOLTA_COMPUTE_A.
