You can add: Tested-by: Gaku Inami The patches have been tested on: 3. Renesas R-Car H3 : 4+4 Cortex A57/A53 Results: Single runs with completion time of each task R-Car H3 (tip) total time: 0.9488s total time: 0.9766s total time: 1.3243s total time: 1.6740s R-Car H3 (misfit) total time: 0.9313s total time: 0.9214s total time: 0.9493s total time: 0.9606s 10 run summary (tracking longest running task for each run) R-Car H3 avg max tip 1.6744 1.6780 misfit 0.9616 1.0290 Also, I confirmed that these patches bring performance improvement to some benchmarks(UnixBench, LMbench). So they have very useful for Renesas SoC. [snip] Regards, Inami
