  (** ** Interference and Interfering Workload *)
  (** In this section, we introduce definitions of interference, 
      interfering workload, and a function that bounds cumulative interference. *)

  (** For proper calculation of interference and interfering workload
     of a job, we need to distinguish interference received from other
     jobs of the same task and jobs of other tasks. In that regard, we
     introduce two additional relations. The first relation defines
     whether job [j1] has a higher-than-or-equal-priority than job [j2]
     and [j1] is not equal to [j2]... *)
  Let another_hep_job: JLFP_policy Job :=
    fun j1 j2 => hep_job j1 j2 && (j1 != j2).

  (** ...and the second relation defines whether a job [j1] has a higher-or-equal-priority than 
     job [j2] and the task of [j1] is not equal to task of [j2]. *)
  Let hep_job_from_another_task: JLFP_policy Job :=
    fun j1 j2 => hep_job j1 j2 && (job_task j1 != job_task j2).

  (** In order to introduce the interference, first we need to recall the definition 
     of priority inversion introduced in module analysis.definitions.priority_inversion:
        [ Definition is_priority_inversion t := ]
        [   if sched t is Some jlp then         ]
        [     ~~ higher_eq_priority jlp j       ]
        [   else false.                         ]
     I.e., we say that job [j] is incurring a priority inversion at time [t]
     if there exists a job with lower priority that executes at time [t]. 
     In order to simplify things, we ignore the fact that according to this 
     definition a job can incur priority inversion even before its release 
     (or after completion). All such (potentially bad) cases do not cause
     problems, as each job is analyzed only within the corresponding busy
     interval where the priority inversion behaves in the expected way. *)
  Let is_priority_inversion (j : Job) (t : instant) :=
    is_priority_inversion sched j t.
  
  (** Next, we say that job [j] is incurring interference from another
      job with higher or equal priority at time [t], if there exists a
      job [jhp] (different from [j]) with higher or equal priority
      that executes at time [t]. *)
  Definition is_interference_from_another_hep_job (j : Job) (t : instant) :=
    if sched t is Some jhp then
      another_hep_job jhp j
    else false.
  
  (** Similarly, we say that job [j] is incurring interference from a
      job with higher or equal priority of another task at time [t],
      if there exists a job [jhp] (of a different task) with higher or
      equal priority that executes at time [t]. *)
  Definition is_interference_from_hep_job_from_another_task (j : Job) (t : instant) :=
    if sched t is Some jhp then
      hep_job_from_another_task jhp j
    else false.
  
  (** Now, we define the notion of cumulative interference, called
      [interfering_workload_of_hep_jobs], that says how many units of
      workload are generated by jobs with higher or equal priority
      released at time [t]. *)
  Definition interfering_workload_of_hep_jobs (j : Job) (t : instant) :=
    \sum_(jhp <- arrivals_at arr_seq t | another_hep_job jhp j) job_cost jhp.

  (** 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. *)
  Definition interference (j : Job) (t : instant)  :=
    is_priority_inversion j t || is_interference_from_another_hep_job j t.
  
  (** 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. *)
  Definition interfering_workload (j : Job) (t : instant) :=
    is_priority_inversion j t + interfering_workload_of_hep_jobs j t.

  (** For each of the concepts defined above, we introduce a corresponding cumulative function: *)
  (** (a) cumulative priority inversion... *)
  Definition cumulative_priority_inversion (j : Job) (t1 t2 : instant)  :=
    \sum_(t1 <= t < t2) is_priority_inversion j t.

  (** ... (b) cumulative interference from other jobs with higher or equal priority... *)
  Let cumulative_interference_from_other_hep_jobs (j : Job) (t1 t2 : instant) :=
    \sum_(t1 <= t < t2) is_interference_from_another_hep_job j t.

  (** ... (c) and cumulative interference from jobs with higher or equal priority from other tasks... *)
  Definition cumulative_interference_from_hep_jobs_from_other_tasks (j : Job) (t1 t2 : instant) :=
    \sum_(t1 <= t < t2) is_interference_from_hep_job_from_another_task j t.
  
  (** ... (d) cumulative interference... *)
  Let cumulative_interference (j : Job) (t1 t2 : instant) := \sum_(t1 <= t < t2) interference j t.

  (** ... (e) cumulative workload from jobs with higher or equal priority... *)
  Let cumulative_interfering_workload_of_hep_jobs (j : Job) (t1 t2 : instant) :=
    \sum_(t1 <= t < t2) interfering_workload_of_hep_jobs j t.

  (** ... (f) and cumulative interfering workload. *)
  Let cumulative_interfering_workload (j : Job) (t1 t2 : instant) :=
    \sum_(t1 <= t < t2) interfering_workload j t.

  (** Instantiated functions usually do not have any useful lemmas about them. In order to
     reuse existing lemmas, we need to prove equivalence of the instantiated functions to 
     some conventional notions. The instantiations given in this file are equivalent to 
     service and workload. Further, we prove these equivalences formally. *)
  
  (** Before we present the formal proofs of the equivalences, we recall
     the notion of workload of higher or equal priority jobs. *)
  Let workload_of_other_hep_jobs (j : Job) (t1 t2 : instant) :=
    workload_of_jobs (fun jhp => another_hep_job jhp j) (arrivals_between t1 t2).

  (** Similarly, we recall notions of service of higher or equal priority jobs from other tasks... *)
  Let service_of_hep_jobs_from_other_tasks (j : Job) (t1 t2 : instant) :=
    service_of_jobs sched (fun jhp => hep_job_from_another_task jhp j)
                    (arrivals_between t1 t2) t1 t2.
  
  (** ... and service of all other jobs with higher or equal priority. *)
  Let service_of_other_hep_jobs (j : Job) (t1 t2 : instant) :=
    service_of_jobs sched (fun jhp => another_hep_job jhp j) (arrivals_between t1 t2) t1 t2.
    
  (** ** Equivalences *)
  (** In this section we prove a few equivalences between the definitions obtained by 
      instantiation of definitions from the Abstract RTA module (interference and
      interfering workload) and definitions corresponding to the conventional concepts.
      
      As it was mentioned previously, instantiated functions of interference and 
      interfering workload usually do not have any useful lemmas about them. However,
      it is possible to prove their equivalence to the more conventional notions like 
      service or workload. Next we prove the equivalence between the instantiations 
      and conventional notions. *)
  Section Equivalences.
    
    (** We prove that we can split cumulative interference into two parts: (1) cumulative priority 
       inversion and (2) cumulative interference from jobs with higher or equal priority. *)
