thread library for i386, amd64, and ia64. For alpha
and sparc64 the library is not changed and remains libkse,
and links are installed so that libpthread -> libc_r.
The gcc -pthread option will be changed in a separate
commit so that it links to -lpthread instead of -lc_r.
Approved by: re@
interrupt handler so that no locks are needed, and schedules the
command completion routine with a taskqueue_fast. This also corrects the
locking in the command thread and removes the need for operation flags.
Simple load tests show that this is now considerably faster than FreeBSD 4.x
in the SMP case when multiple i/o tasks are running.
all MFS root options together and in the same order on all archs.
- Drop support for using the no longer existing 2.88 floppy image for CD
booting on i386 via the EMUL_BOOT variable.
- Use a stock loader on the boot floppy rather than one without forth.
- Force the gzip of the mfsroot in release.9 to succeed. This is useful
when doing lots of rereleases when testing floppy changes.
- If an acpi kernel module exists, stick it on the boot floppy and for
now always load it after the kernel.
- Fixed spelling of NO_FLOPPIES to unbreak snapshot building on
architectures that don't support them (as installation source).
- Don't rely on CVS setting execution bits on the shell script.
(This is also consistent with the rest of this makefile.)

UNI protocols. The actual test suites are not in these directories because
of their size. One needs to install the atmsupport port (the script
will remind you, if it cannot find the port).
The SSCOP test suite includes booth the ETSI and the ITU-T test suite,
the SSCF-UNI test suite is home grown and the UNI test suite is the
P2MP ETSI test suite. Others may follow.
"scheduler" here has very little to do with scheduling. It is actually
the swapper, and it really must be the last SYSINIT'ed item like its
comment says, since proc0 metamorphoses into swapper by calling
scheduler() last in mi_start(), and scheduler() never returns.. Rev.1.29
of subr_4bsd.c broke this by adding another SI_ORDER_FIRST item
(kproc_start() for schedcpu_thread() onto the SI_SUB_RUN_SCHEDULER_LIST.
The sorting of SYSINITs with identical orders (at all levels) is
apparently nondeterministic, so this resulted in schedule() sometimes
being called second last and schedcpu_thread() not being called at all.
This quick fix just changes the code to almost match the comment
(SI_ORDER_FIRST -> SI_ORDER_ANY). "LAST" is misspelled "ANY", and
there is no way to ensure that there is only 1 very lst SYSINIT.
A more complete fix would remove the SYSINIT obfuscation.
what do I get for my troubles? libc breaks offcourse!
Reimplement a hack (in libthr) that allows libc to use
rwlocks without initializing them first. The hack was reimplemented
so that only a private libc version of the rwlock locking functions
initializes an uninitialized rwlock. The application version will
correctly fail.
the system call got interrupted and the absolute timeout is
converted to a relative timeout, it may happen that we get a
negative number. In such a case, simply set the timeout to
zero so that if the event that the thread wants to wait for has
happened it can still return successfully, but if it hasn't
happened then the thread doesn't suspend indefinitely. This should
fix certain applications (including mozilla) that seem to hang
indefinitely sometimes.
