(** * Abstract RTA for FP-schedulers with Bounded Priority Inversion *) (** In this module we instantiate the Abstract Response-Time analysis (aRTA) to FP-schedulers for ideal uni-processor model of real-time tasks with arbitrary arrival models. *) (** Given FP priority policy and an ideal uni-processor scheduler model, we can explicitly specify [interference], [interfering_workload], and [interference_bound_function]. In this settings, we can define natural notions of service, workload, busy interval, etc. The important feature of this instantiation is that we can induce the meaningful notion of priority inversion. However, we do not specify the exact cause of priority inversion (as there may be different reasons for this, like execution of a non-preemptive segment or blocking due to resource locking). We only assume that that a priority inversion is bounded. *) Section AbstractRTAforFPwithArrivalCurves. (** Consider any type of tasks ... *) Context {Task : TaskType}. Context `{TaskCost Task}. Context `{TaskRunToCompletionThreshold Task}. (** ... and any type of jobs associated with these tasks. *) Context {Job : JobType}. Context `{JobTask Job Task}. Context {Arrival : JobArrival Job}. Context {Cost : JobCost Job}. Context `{JobPreemptable Job}. (** Consider an FP policy that indicates a higher-or-equal priority relation, and assume that the relation is reflexive. Note that we do not relate the FP policy with the scheduler. However, we define functions for Interference and Interfering Workload that actively use the concept of priorities. We require the FP policy to be reflexive, so a job cannot cause lower-priority interference (i.e. priority inversion) to itself. *) Context `{FP_policy Task}. Hypothesis H_priority_is_reflexive : reflexive_priorities. (** Consider any arrival sequence with consistent, non-duplicate arrivals. *) Variable arr_seq : arrival_sequence Job.

(** ** Instantiation of Interference *) (** We say that job [j] incurs interference at time [t] iff it cannot execute due to a higher-or-equal-priority job being scheduled, or if it incurs a priority inversion. *) #[local] Instance ideal_jlfp_interference : Interference Job := ideal_jlfp_interference arr_seq sched. (** ** Instantiation of Interfering Workload *) (** The interfering workload, in turn, is defined as the sum of the priority inversion function and interfering workload of jobs with higher or equal priority. *) #[local] Instance ideal_jlfp_interfering_workload : InterferingWorkload Job := ideal_jlfp_interfering_workload arr_seq sched.

(** Let max_arrivals be a family of valid arrival curves, i.e., for any task [tsk] in ts [max_arrival tsk] is (1) an arrival bound of [tsk], and (2) it is a monotonic function that equals 0 for the empty interval [delta = 0]. *) Context `{MaxArrivals Task}.

That is, [task_rtct tsk] is (1) no bigger than [tsk]'s cost, (2) for any job of task [tsk] [job_rtct] is bounded by [task_rtct]. *) Hypothesis H_valid_run_to_completion_threshold : valid_task_run_to_completion_threshold arr_seq tsk.

Let job_backlogged_at := backlogged sched. Let response_time_bounded_by := task_response_time_bound arr_seq sched.

(** Similarly, we define the request bound function of all tasks other than [tsk] with higher-or-equal priority (with respect to [tsk]). *) Let total_ohep_rbf := total_ohep_request_bound_function_FP ts tsk. (** Assume that there exists a constant [priority_inversion_bound] that bounds the length of any priority inversion experienced by any job of [tsk]. Since we analyze only task [tsk], we ignore the lengths of priority inversions incurred by any other tasks. *) Variable priority_inversion_bound : duration. Hypothesis H_priority_inversion_is_bounded : priority_inversion_is_bounded_by_constant arr_seq sched tsk priority_inversion_bound. (** Let [L] be any positive fixed point of the busy interval recurrence. *) Variable L : duration. Hypothesis H_L_positive : L > 0. Hypothesis H_fixed_point : L = priority_inversion_bound + total_hep_rbf L. (** To reduce the time complexity of the analysis, recall the notion of search space. Intuitively, this corresponds to all "interesting" arrival offsets that the job under analysis might have with regard to the beginning of its busy-window. *) Definition is_in_search_space A := (A < L) && (task_rbf A != task_rbf (A + ε)). (** Let [R] be a value that upper-bounds the solution of each response-time recurrence, i.e., for any relative arrival time [A] in the search space, there exists a corresponding solution [F] such that [R >= F + (task cost - task lock-in service)]. *) Variable R : duration. Hypothesis H_R_is_maximum : forall (A : duration), is_in_search_space A -> exists (F : duration), A + F >= priority_inversion_bound + (task_rbf (A + ε) - (task_cost tsk - task_rtct tsk)) + total_ohep_rbf (A + F) /\ R >= F + (task_cost tsk - task_rtct tsk). (** Finally, we define the interference bound function ([IBF_other]). [IBF_other] bounds the interference if tasks are sequential. Since tasks are sequential, we exclude interference from other jobs of the same task. For FP, we define [IBF_other] as the sum of the priority interference bound and the higher-or-equal-priority workload. *) Let IBF_other (R : duration) := priority_inversion_bound + total_ohep_rbf R. (** ** Filling Out Hypotheses Of Abstract RTA Theorem *) (** In this section we prove that all preconditions necessary to use the abstract theorem are satisfied. *) Section FillingOutHypothesesOfAbstractRTATheorem. (** Recall that [L] is assumed to be a fixed point of the busy interval recurrence. Thanks to this fact, we can prove that every busy interval (according to the concrete definition) is bounded. In addition, we know that the conventional concept of busy interval and the one obtained from the abstract definition (with the interference and interfering workload) coincide. Thus, it follows that any busy interval (in the abstract sense) is bounded. *)

eapply instantiated_busy_interval_equivalent_busy_interval; rt_eauto. Qed. (** Next, we prove that [IBF_other] is indeed an interference bound. Recall that in module abstract_seq_RTA hypothesis [task_interference_is_bounded_by] expects to receive a function that maps some task [tsk], the relative arrival time of a job [j] of task [tsk], and the length of the interval to the maximum amount of interference. However, in this module we analyze only one task -- [tsk], therefore it is “hard-coded” inside the interference bound function [IBF_other]. Moreover, in case of a model with fixed priorities, interference that some job [j] incurs from higher-or-equal priority jobs does not depend on the relative arrival time of job [j]. Therefore, in order for the [IBF_other] signature to match the required signature in module [abstract_seq_RTA], we wrap the [IBF_other] function in a function that accepts, but simply ignores, the task and the relative arrival time. *)
