      Restructure directory + Add jitter-aware RTA · a5f12a43
      Felipe Cerqueira authored
      - Added definitions and implementation of jitter-aware RTA for
        uniprocessor scheduling.
      - The Prosa directory was restructured to better accomodate the different
        types of arrival sequences and schedules.

      Major commit: Suspension-Oblivious Analysis · 843c6ffc
      Felipe Cerqueira authored
      - Add generic definition of job suspension based on the cumulative service
      - Define the dynamic suspension model (based on task suspension bounds)
      - Add suspension semantics for uniprocessor schedules
      - Formalize reduction from suspension-aware schedule to suspension-oblivious
        schedule by inflating costs (works with JLDP policies and non-unique priorities)
      - Formalize suspension-oblivious FP RTA using the reduction
      - Add implementation of a concrete suspension-aware scheduler
      - Test suspension-oblivious FP RTA with an actual task set
      - Add simpler definition for JLFP policies
      - Generalize busy interval lemmas from FP to JLFP scheduling

      Major commit: Uniprocessor RTA · ac6f0d4e
      Felipe Cerqueira authored
      This commit contains several updates related to uniprocessor scheduling.
      - Basic definitions of uniprocessor scheduling (see model/uni)
      - Definitions of worload and service for generic sets of jobs (see service.v and workload.v in model/uni)
      - Definitions and lemmas about busy intervals (see model/uni/basic/busy_interval.v)
      - Definition of an arrival bound for sporadic tasks (see model/arrival_bounds.v)
      - Definitions and correctness proofs of the RTA for FP scheduling
        (also works with non-unique priorities and arbitrary deadlines, but gives pessimistic bounds)
      - Implementation of the FP RTA to check for contradictory assumptions
      In addition, we have also defined partitioned scheduling and proven how it relates
      with uniprocessor (see model/partitioned).

      Major Changes in RTA and Directory Structure · 32126a75
      Felipe Cerqueira authored
      - Removed unnecessary assumption in RTA about task precedence/no intra-task parallelism.
      - Scheduler models and analyses are organized in separate modules/folders.
      - Added RTA for FP and EDF for schedulers with release jitter.
      - The scheduling invariants were split into more fine-grained assumptions:
        (a) scheduler is work-conserving
        (b) scheduler enforces FP/JLDP priority X
      - New helper lemmas about counting, and sorted/uniq lists
      - Inclusion of tactics feed and feed_n (see documentation).
      - Added a Makefile generator
