-Subject: [PATCH 14/15] sched/eevdf: Delay dequeue
-
-For tasks that have negative-lag (have received 'excess' service), delay the
-dequeue and keep them in the runnable tree until they're elegible again. Or
-rather, keep them until they're selected again, since finding their elegibility
-crossover point is expensive.
-
-The effect is a bit like sleeper bonus, the tasks keep contending for service
-until either they get a wakeup or until they're selected again and are really
-dequeued.
-
-This means that any actual dequeue happens with positive lag (serviced owed)
-and are more readily ran when wakeup.

-Subject: [PATCH 15/15] sched/eevdf: Use sched_attr::sched_runtime to set
- request/slice suggestion
-
-Allow applications to directly set a suggested request/slice length using
-sched_attr::sched_runtime.
-
-The implementation clamps the value to: 0.1[ms] <= slice <= 100[ms]
-which is 1/10 the size of HZ=1000 and 10 times the size of HZ=100.
-
-Applications should strive to use their periodic runtime at a high
-confidence interval (95%+) as the target slice. Using a smaller slice
-will introduce undue preemptions, while using a larger value will
-increase latency.
-
-For all the following examples assume a scheduling quantum of 8, and for
-consistency all examples have W=4:
-
-  {A,B,C,D}(w=1,r=8):

+
+This reverts commit 3592cc20beeece83db4c50a0f400e2dd15139de9.
+
+The enablement for the new OD mechanism completed. Also, the support for
+fan control related OD feature has been added via this new mechanism.
+Thus, it is time to bring back the SMU13 OD support.

+Subject: [PATCH] drm/amd/pm: Fix clock reporting for SMUv13.0.6
+
+On SMU v13.0.6, effective clocks are reported by FW which won't exactly
+match with DPM level. Report the current clock based on the values
+matching closest to the effective clock. Also, when deep sleep is
+applied to a clock, report it with a special level "S:" as in sample
+clock levels below
+
+S: 19Mhz *
+0: 615Mhz
+1: 800Mhz
+2: 888Mhz
+3: 1000Mhz
