15 years agoIntroduce support for adaptive spinning in lockmgr.
Attilio Rao [Wed, 17 Jun 2009 01:55:42 +0000 (01:55 +0000)]
Introduce support for adaptive spinning in lockmgr.
Actually, as it did receive few tuning, the support is disabled by
default, but it can opt-in with the option ADAPTIVE_LOCKMGRS.
Due to the nature of lockmgrs, adaptive spinning needs to be
selectively enabled for any interested lockmgr.
The support is bi-directional, or, in other ways, it will work in both
cases if the lock is held in read or write way.  In particular, the
read path is passible of further tunning using the sysctls
debug.lockmgr.retries and debug.lockmgr.loops .  Ideally, such sysctls
should be axed or compiled out before release.

Addictionally note that adaptive spinning doesn't cope well with
LK_SLEEPFAIL.  The reason is that many (and probabilly all) consumers
of LK_SLEEPFAIL are mainly interested in knowing if the interlock was
dropped or not in order to reacquire it and re-test initial conditions.
This directly interacts with adaptive spinning because lockmgr needs
to drop the interlock while spinning in order to avoid a deadlock
(further details in the comments inside the patch).

Final note: finding someone willing to help on tuning this with
relevant workloads would be either very important and appreciated.

The code that was in place in exit1() was mainly based on code from the

ran a system that had two TTY layers in place at the same time. It is
now sufficient to do the following:

- Remove references from the session structure to the TTY vnode and the
  session leader.

- If we have a controlling TTY and the session used by the TTY is equal
  to our session, send the SIGHUP.

- If we have a vnode to the controlling TTY which has not been revoked,
  revoke it.

While there, change sys/kern/tty.c to use s_ttyp in the comparison

fail with any errors.  In practice, while the manpages for NetBSD and
OpenBSD claim that they return EINTR, they ignore internal errors from
close() and never return EINTR.  DFly does return EINTR, but for the common
use case (closing fd's prior to execve()), the caller really wants all
fd's closed and returning EINTR just forces callers to call closefrom() in
a loop until it stops failing.

Forbid multi-vector MSI interrupt vectors migration to another CPU once
allocated. MSI have strict vectors allocation requirements, which are not
satisfied now during reallocation. This is not the best possible solution,
but better then just broken, as it was.

15 years ago- Add a way to change filter oversampling factor through

- Add a way to change filter oversampling factor through
  FEEDER_RATE_PRESET "OVERSAMPLING_FACTOR:X .. .." where
  X = log2(oversampling factor).

- Lower down default filter oversampling factor from 128
  (log2 = 7) to 32 (log2 = 5), saving worth of 80 Kb.
  The use of better polynomial interpolator will raise
  its conversion quality/accuracy to match (or slightly
  better) with previous settings.

- Bump driver version.
