and thread_at_kernel_exit() are always called for userland threads at the appropriate
situation (note, I've renamed those from *_atkernel_*).
The timing should be more accurate this way, and the thread::last_time_type field
is no longer needed: all interrupts are now added to the kernel time (where the
time is actually spent).

limit, but this is not yet enforced. Added getter functions.
team_init() now returns a status_t.
System info stuff is now globally initialized in main().
get_system_info() now also reports the number of used pages, and calls the
architecture dependent function.

arguments (which should have taken the dumped thread).
Improved "thread" debug output to have all data values at the same column.

Fixed a bug in the team thread start: it did not set sizeLeft correctly
before copying the arguments - shouldn't have had any consequences, though,
as the size of the arguments is known before.
Added a comment explaining the current layout of the main thread stack area.
Now makes use of B_STACK_AREA and B_KERNEL_STACK_AREA.
fill_thread_info() did not correctly set thread_info::stack_end.

Fixed a bug in snooze_etc(): it could define both, B_ABSOLUTE_TIMEOUT and
B_RELATIVE_TIMEOUT at the same time.

Improved the threads list: despite looking much better, it now also prints
out the semaphore number a thread is waiting on.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9530 a95241bf-73f2-0310-859d-f6bbb57e9c96
- we now have a working process group/session model. Implemented related syscalls
and the kernel backend, some POSIX process functions are now available in the
kernel as well.
- dying teams now monitor their exitus by leaving death_entry structures in
their parent team.
- Implemented wait_for_child() for pid == -1 and pid > 0; IOW waiting for process
groups is missing yet. Hasn't yet been tested intensively.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9350 a95241bf-73f2-0310-859d-f6bbb57e9c96
no longer abuse the semaphore mechanism to carry an extra status value,
instead, wait_for_thread() registers a death_entry with the thread that
will be filled upon exit.
Removed delete_sem_etc() as it's no longer of use or available.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9323 a95241bf-73f2-0310-859d-f6bbb57e9c96
flag set.
Fixes _user_wait_for_thread() which returned an invalid return code in case
of error.
Some minor cosmetics.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9321 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed the way a vm_address_space is deleted: instead of having to explicitly
call vm_delete_aspace(), the last vm_put_aspace() will remove it.

potential bug if MAIN_STACK_SIZE and STACK_SIZE would have been different.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9190 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed thread_atkernel_exit() to look less broken - the way and when it's
called should still be investigated: NewOS looks a lot cleaner here.
create_thread() now creates the kernel stack upfront, so that it can easily
bail out of that fails. The user stack creation now makes use of B_BASE_ADDRESS
and is therefore a lot better and simpler. In case user stack creation failed,
it should now be able to handle that a lot more gracefully - but that hasn't
been tested yet...
Some cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7897 a95241bf-73f2-0310-859d-f6bbb57e9c96
thread exit - get_death_stack() now returns the interrupt state so that
it can be restored correctly later.

The syscall is not yet connected, and the code has not yet been tested.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7179 a95241bf-73f2-0310-859d-f6bbb57e9c96
Incorporated NewOS change 1930: sends the parent SIGCHLD if the team
goes away.
create_thread() now returns B_BAD_TEAM_ID when the team is in death state
instead of ERR_TASK_PROC_DELETED.
Cleaned headers.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6997 a95241bf-73f2-0310-859d-f6bbb57e9c96
its semaphores get deleted, thanks to Jack Burton for reporting.

else is not found here. The BeOS kernel also exports these two *_etc()
functions, and we might want to do that, too.
{receive|send}_data() are now interruptible from userland, but not when
called from the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6700 a95241bf-73f2-0310-859d-f6bbb57e9c96
Cleaned up _get_thread_info() & _get_next_thread_info() - factored out
the thread_info setup into fill_thread_info().
Is now using team_is_alive() instead of team_get_team_struct().
Replaced SYS_MAX_OS_NAME_LEN with B_OS_NAME_LENGTH.
Banned strncpy() in favor for strlcpy().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6683 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added our license to the updated source files.
Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6672 a95241bf-73f2-0310-859d-f6bbb57e9c96
implementing a more efficient on_exit_thread().
Note, this extra parameter is currently only used for user space code,
not yet in the kernel; thus on_exit_thread() is not available in the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3075 a95241bf-73f2-0310-859d-f6bbb57e9c96
thread code now properly traces time spent in user vs kernel mode. The code was
just plain broken before

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2599 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now directly exports (as is, most of) the kernel thread API.
Now has user_*() functions where needed.
Moved thread_set_priority() from scheduler.c to set_thread_priority().
Renamed thread_wait_on_thread() to wait_for_thread().
user_get_thread_info() now uses user_strlcpy() instead of user_strncpy().
Fixed the snooze() implementation - it now returns B_OK where appropriate. Now all snooze()
calls will call snooze_etc().
New private call spawn_kernel_thread_etc() to replace thread_create_kernel_thread_etc().
Moved some functions around.

arch_cpu: could have used the TLS_SIZE macro in one place, removed
a now unused variable, assignments to tss_loaded are now booleans.
thread.c: added the new fields to _dump_thread_info().
