In the latest kernel, sched_ext API has changed in two areas: - ops.prep_enable/cancel_enable/enable/disable() replaced with ops.init_task/enable/disable/exit_task(). - scx_bpf_dispatch() can now be called from ops.select_cpu(). Also, SCX_ENQ_LOCAL flag is removed. Instead, users can call scx_bpf_select_cpu_dfl() from ops.select_cpu() and use the @is_idle out param value to determine whether to dispatch directly. This commit updates all schedules so that they build. - Init functions renamed / merged / split. - ops.select_cpu() is added to several schedulers and local direct disptching logic is moved there. This is the minimum update which is need to make the schedulers build and work. It needs further update to e.g. move vtime udpates to ops.enable(). |
