Overview -+============= -+ -+The CacULE CPU scheduler is based on interactivity score mechanism. -+The interactivity score is inspired by the ULE scheduler (FreeBSD -+scheduler). -+ -+1.1 About CacULE Scheduler -+-------------------------- -+ -+ - Each CPU has its own runqueue. -+ -+ - NORMAL runqueue is a linked list of sched_entities (instead of RB-Tree). -+ -+ - RT and other runqueues are just the same as the CFS's. -+ -+ - Wake up tasks preempt currently running tasks if its interactivity score value -+ is higher. -+ -+ -+1.2. Complexity -+---------------- -+ -+The complexity of Enqueue and Dequeue a task is O(1). -+ -+The complexity of pick the next task is in O(n), where n is the number of tasks -+in a runqueue (each CPU has its own runqueue). -+ -+Note: O(n) sounds scary, but usually for a machine with 4 CPUS where it is used -+for desktop or mobile jobs, the maximum number of runnable tasks might not -+exceeds 10 (at the pick next run time) - the idle tasks are excluded since they -+are dequeued when sleeping and enqueued when they wake up. -+ -+ -+2. The CacULE Interactivity Score -+======================================================= -+ -+The interactivity score is inspired by the ULE scheduler (FreeBSD scheduler). -+For more information see: https://web.cs.ucdavis.edu/~roper/ecs150/ULE.pdf -+CacULE doesn't replace CFS with ULE, it only changes the CFS' pick next task -+mechanism to ULE's interactivity score mechanism for picking next task to run. -+ -+ -+2.3 sched_interactivity_factor -+================= -+Sets the value *m* for interactivity score calculations. See Figure 1 in -+https://web.cs.ucdavis.edu/~roper/ecs150/ULE.pdf -+The default value of in CacULE is 10 which means that the Maximum Interactive -+Score is 20 (since m = Maximum Interactive Score / 2). -+You can tune sched_interactivity_factor with sysctl command: -+ -+ sysctl kernel.sched_interactivity_factor=50 -+ -+This command changes the sched_interactivity_factor from 10 to 50. -+ -+ -+3. Scheduling policies -+======================= -+ -+CacULE some CFS, implements three scheduling policies: -+ -+ - SCHED_NORMAL (traditionally called SCHED_OTHER): The scheduling -+ policy that is used for regular tasks. -+ -+ - SCHED_BATCH: Does not preempt nearly as often as regular tasks -+ would, thereby allowing tasks to run longer and make better use of -+ caches but at the cost of interactivity. This is well suited for -+ batch jobs. -+ -+ - SCHED_IDLE: This is even weaker than nice 19, but its not a true -+ idle timer scheduler in order to avoid to get into priority -+ inversion problems which would deadlock the machine. -diff --git a/include/linux/sched.h b/include/linux/sched.h -index 76cd21fa5501..a4d58d27fc72 100644 ---- a/include/linux/sched.h -+++ b/include/linux/sched.h -@@ -448,16 +448,29 @@ struct sched_statistics { - #endif - }; - -+#ifdef CONFIG_CACULE_SCHED -+struct cacule_node { -+ struct cacule_node* next; -+ struct cacule_node* prev; -+ u64 cacule_start_time; -+ u64 vruntime; -+}; -+#endif -+ - struct sched_entity { - /* For load-balancing: */ - struct load_weight load; - struct rb_node run_node; -+#ifdef CONFIG_CACULE_SCHED -+ struct cacule_node cacule_node; -+#else -+ u64 vruntime; -+#endif - struct list_head group_node; - unsigned int on_rq; - - u64 exec_start; - u64 sum_exec_runtime; -- u64 vruntime; - u64 prev_sum_exec_runtime; - - u64 nr_migrations; -diff --git a/include/linux/sched/sysctl.h b/include/linux/sched/sysctl.h -index 3c31ba88aca5..cb819c3d86f3 100644 ---- a/include/linux/sched/sysctl.h -+++ b/include/linux/sched/sysctl.h -@@ -31,6 +31,12 @@ extern unsigned int sysctl_sched_min_granularity; - extern unsigned int sysctl_sched_wakeup_granularity; - extern unsigned int sysctl_sched_child_runs_first; - -+#ifdef CONFIG_CACULE_SCHED -+extern int interactivity_factor; -+extern unsigned int interactivity_threshold; -+extern int cacule_max_lifetime; -+#endif -+ - enum sched_tunable_scaling { - SCHED_TUNABLESCALING_NONE, - SCHED_TUNABLESCALING_LOG, -diff --git a/init/Kconfig b/init/Kconfig -index fc4c9f416fad..16676cfd11d7 100644 ---- a/init/Kconfig -+++ b/init/Kconfig -@@ -825,6 +825,17 @@ config UCLAMP_BUCKETS_COUNT - - endmenu - -+config CACULE_SCHED -+ bool "CacULE CPU scheduler" -+ default y -+ help -+ The CacULE CPU scheduler is based on interactivity score mechanism. -+ The interactivity score is inspired by the ULE scheduler (FreeBSD -+ scheduler). -+ -+ If unsure, say Y here. -+ -+ - # - # For architectures that want to enable the support for NUMA-affine scheduler - # balancing logic: -@@ -1208,6 +1219,7 @@ config SCHED_AUTOGROUP - select CGROUPS - select CGROUP_SCHED - select FAIR_GROUP_SCHED -+ default y - help - This option optimizes the scheduler for common desktop workloads by - automatically creating and populating task groups.
