From perf data, found a significant overhead at ring id check in the function get_opcode. This inline function is frequently used. Since Intel static predictor will predict the branch to fall through so the prediction most fail. This is wasting CPU pipeline resource. We do not need check the engine id everywhere, it should be reliable. Signed-off-by: Changbin Du <changbin.du@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> |
