2 years agomove pf_purge out from under the kernel lock and avoid the hogging cpu
dlg [Mon, 7 Nov 2022 12:56:38 +0000 (12:56 +0000)]
move pf_purge out from under the kernel lock and avoid the hogging cpu

this also avoids holding NET_LOCK too long.

the main change is done by running the purge tasks in systqmp instead
of systq. the pf state list was recently reworked so iteration over
the state can be done without blocking insertions.

however, scanning a lot of states can still take a lot of time, so
this also makes the state list scanner yield if it has spent too
much time running.

the other purge tasks for source nodes, rules, and fragments have
been moved to their own timeout/task pair to simplify the time
accounting.

in my environment, before this change pf purges often took 10 to
50ms. the softclock thread runs next to it often took a similar
amount of time, presumably because they ended up spinning waiting
for each other. after this change the pf_purges are more like 6 to
12ms, and dont block softclock. most of the variability in the runs
now seems to come from contention on the net lock.

cheloha [Sat, 5 Nov 2022 19:29:45 +0000 (19:29 +0000)]
clockintr(9): initial commit

clockintr(9) is a machine-independent clock interrupt scheduler.  It
emulates most of what the machine-dependent clock interrupt code is
doing on every platform.  Every CPU has a work schedule based on the
system uptime clock.  For now, every CPU has a hardclock(9) and a
statclock().  If schedhz is set, every CPU has a schedclock(), too.

This commit only contains the MI pieces.  All code is conditionally
compiled with __HAVE_CLOCKINTR.  This commit changes no behavior yet.

At a high level, clockintr(9) is configured and used as follows:

1. During boot, the primary CPU calls clockintr_init(9).  Global state
   is initialized.
2. Primary CPU calls clockintr_cpu_init(9).  Local, per-CPU state is
   initialized.  An "intrclock" struct may be installed, too.
3. Secondary CPUs call clockintr_cpu_init(9) to initialize their
   local state.
4. All CPUs repeatedly call clockintr_dispatch(9) from the MD clock
   interrupt handler.  The CPUs complete work and rearm their local
   interrupt clock, if any, during the dispatch.
5. Repeat step (4) until the system shuts down, suspends, or hibernates.
6. During resume, the primary CPU calls inittodr(9) and advances the
   system uptime.
7. Go to step (2).  This time around, clockintr_cpu_init(9) also
   advances the work schedule on the calling CPU to skip events that
   expired during suspend.  This prevents a "thundering herd" of
   useless work during the first clock interrupt.

In the long term, we need an MI clock interrupt scheduler in order to
(1) provide control over the clock interrupt to MI subsystems like
timeout(9) and dt(4) to improve their accuracy, (2) provide drivers
like acpicpu(4) a means for slowing or stopping the clock interrupt on
idle CPUs to conserve power, and (3) reduce the amount of duplicated
code in the MD clock interrupt code.

Before we can do any of that, though, we need to switch every platform
over to using clockintr(9) and do some cleanup.

Prompted by "the vmm(4) time bug," among other problems, and a
discussion at a2k19 on the subject.  Lots of design input from
