Generalizd architecture for GEDF-style scheduelrs to reduce code redundancy.wip-refactored-gedf
This patch hoists nearly all of the non-GEDF specific code (decision
making (GEDF) vs. carrying out decisions (non-specific)) out of
sched_gsn_edf.c and into a new generic sched_global_plugin architecture.
A new struct, sched_global_plugin, provides the needed hooks for other
GEDF-style schedulers to reuse the non-scheduler-specific code.
You may conceptualize this new architecture (in OO-terms) as:
* sched_plugin is the parent of sched_global_plugin.
* sched_global_plugin is the parent of gsn_edf_plugin.
* Both sched_plugin and sched_global_plugin are "pure virtual"
This patch drastically reduces the amount of code needed to support
G-EDF, EDZL, (Adaptive) EDZL, etc.
