* ithread(9): update functions to current dayMitchell Horne2022-10-151-1/+1
| | | | | | | | | | | | | | | | | | | The public KPI is now intr_event_**, - Convert existing documented functions to their equivalents. - Fix up the function arguments - Fix up the possible error return values for each - Remove ithread_schedule() completely - Rename man page to intr_event(9) - Update cross-references Future changes will update the descriptive text for these functions.

* swi(9): remove BUGS sectionMitchell Horne2022-10-121-5/+1
| | | | | | | | | | | | | Most of these globals have been removed, save for clk_intr_event. This one is appropriate to keep in sys/interrupt.h, despite the fact that it has only one consumer. Bump .Dd for this and previous changes. Reviewed by: markj MFC after: 1 week Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D36939

| | | | | | | | | | It can be static within uart_tty.c. It is an open question whether there remains any real benefit to having uart instances share a swi thread.

* swi(9): clean up description of clk_intr_eventMitchell Horne2022-10-121-11/+4
| | | | | | | | | | | From what I can tell, setdelayed() was removed so long ago that its mention is more likely to be confusing than helpful. We now have a manpage for hardclock(9), so reference that. Reviewed by: markj MFC after: 1 week Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D36937

* Allow swi_sched() to be called from NMI context.Alexander Motin2020-07-251-2/+9
| | | | | | | | | | | | | | | | | | For purposes of handling hardware error reported via NMIs I need a way to escape NMI context, being too restrictive to do something significant. To do it this change introduces new swi_sched() flag SWI_FROMNMI, making it careful about used KPIs. On platforms allowing IPI sending from NMI context (x86 for now) it immediately wakes clk_intr_event via new IPI_SWI, otherwise it works just like SWI_DELAY. To handle the delayed SWIs this patch calls clk_intr_event on every hardclock() tick. MFC after: 2 weeks Sponsored by: iXsystems, Inc.
