The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=ed998d1c24dba600cf5fdf669370f1e2dfad3e47 commit ed998d1c24dba600cf5fdf669370f1e2dfad3e47 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2022-07-14 20:13:35 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2022-07-14 20:13:35 +0000 ithreads: Support priority adjustment by schedulers. Use sched_wakeup instead of sched_add when marking an ithread runnable. This allows schedulers to reset their internal time slice tracking state and restore the base ithread priority when an ithread resumes from idle.
