  Add cv_fdrestart() [...]
  Use cv_fdrestart() to implement fo_restart.
  Simplify/streamline pipes a little bit [...]

This changes have caused regressions and need to be debugged.
The cv_fdrestart() addition needs more discussion.

Add cv_fdrestart() (better name suggestions welcome):

Like cv_broadcast(), but make any LWPs that share the same file descriptor
table as the caller return ERESTART when resuming.  Used to dislodge LWPs
waiting for I/O that prevent a file descriptor from being closed, without
upsetting access to the file (not descriptor) made from another direction.

Remove timedwaitclock.

This did not fix the bug I hoped it would fix in futex, and needs
more design thought.  Might redo it somewhat differently later.

Revision 1.16 / (download) - annotate - [select for diffs], Sun May 3 01:24:37 2020 UTC (3 years, 11 months ago) by riastradh

Changes since 1.15: +6 -1 lines

New cv_timedwaitclock, cv_timedwaitclock_sig.

Usage: given a struct timespec timeout copied from userland, along
with a clockid and TIMER_* flags,

        error = cv_timedwaitclock(cv, lock, timeout, clockid, flags,
            DEFAULT_TIMEOUT_EPSILON);
        if (error)
                /* fail */

If flags is relative (i.e., (flags & TIMER_ABSTIME) == 0), then this
deducts the time spent waiting from timeout, so you can run it in a
loop:

        struct timespec timeout;

        error = copyin(SCARG(uap, timeout), &timeout, sizeof timeout);
        if (error)
                return error;

        mutex_enter(lock);
        while (!ready()) {
                error = cv_timedwaitclock_sig(cv, lock, &timeout,
                    SCARG(uap, clockid), SCARG(uap, flags),
                    DEFAULT_TIMEOUT_EPSILON);
                if (error)
                        break;
        }
        mutex_exit(lock);

CAVEAT: If the system call is interrupted by a signal with SA_RESTART
so cv_timedwaitclock_sig fails with ERESTART, then the system call
will be restarted with the _original_ relative timeout, not counting
the time that was already spent waiting.  This is a problem but it's
not a problem I want to deal with at the moment.

Change sleepq_t from a TAILQ to a LIST and remove SOBJ_SLEEPQ_FIFO.  Only
select/poll used the FIFO method and that was for collisions which rarely
occur.  Shrinks sleep_t and condvar_t.

Don't pollute <sys/condvar.h> with <sys/mutex.h>.

Instead, forward-declare struct kmutex, since we only need to
describe pointer types to it.

This breaks an include cycle on several architectures:

sys/cpu_data.h
-> sys/condvar.h
-> sys/mutex.h
-> sys/intr.h
-> machine/intr.h
-> machine/cpu.h
-> sys/cpu_data.h

- Give each condition variable its own sleep queue head.  Helps the system
  to scale more gracefully when there are thousands of active threads.
  Proposed on tech-kern@.

- Use LOCKDEBUG to catch some errors in the use of condition variables:

  freeing an active CV
  re-initializing an active CV
  using multiple distinct mutexes during concurrent waits
  not holding the interlocking mutex when calling cv_broadcast/cv_signal
  waking waiters and destroying the CV before they run and exit it

- cv_wakeup: remove this. There are ~zero situations where it's useful.
- cv_wait and friends: after resuming execution, check to see if we have
  been restarted as a result of cv_signal. If we have, but cannot take
  the wakeup (because of eg a pending Unix signal or timeout) then try to
  ensure that another LWP sees it. This is necessary because there may
  be multiple waiters, and at least one should take the wakeup if possible.
  Prompted by a discussion with pooka@.
- typedef struct lwp lwp_t;
- int -> bool, struct lwp -> lwp_t in a few places.
