-Subject: [PATCH] cpuidle: mvebu: Update cpuidle thresholds for Armada XP SOCs
-
-Originally, the thresholds used in the cpuidle driver for Armada SOCs
-were temporarily chosen, leaving room for improvements.
-
-This commit updates the thresholds for the Armada XP SOCs with values
-that positively impact performances:
-
-                                without patch  with patch   vendor kernel
- - iperf localhost (gbit/sec)   ~3.7           ~6.4         ~5.4
- - ioping tmpfs (iops)          ~163k          ~206k        ~179k
- - ioping tmpfs (mib/s)         ~636           ~805         ~699
-
-The idle power consumption is negatively impacted (proportionally less
-than the performance gain), and we are still performing better than
-the vendor kernel here:
-
-                                without patch   with patch  vendor kernel
- - power consumption idle (W)   ~2.4            ~3.2        ~4.4
- - power consumption busy (W)   ~8.6            ~8.3        ~8.6
-
-There is still room for improvement regarding the value of these
-thresholds, they were chosen to mimic the vendor kernel.
-
-This patch only impacts Armada XP SOCs and was tested on Online Labs
-C1 boards. A similar approach can be taken to improve the performances
-of the Armada 370 and Armada 38x SOCs.
-
-Thanks a lot to Thomas Petazzoni, Gregory Clement and Willy Tarreau
-for the discussions and tips around this topic.
