turned off - accessing userland memory. Now, arch_thread_enter_userspace() does that
job, and as a result, may also fail.
* dump_thread() now directly prints the info of the current thread when used without
argument (rather than iterating the thread list to look for the current thread).
* If arch_thread_init_tls() fails upon thread creation, the function will now return
an error.

to other kernel components.
* wait_for_thread_etc() will now search the team's death entries in case the
thread is already gone; also resume_thread() is now done later, and its return
code will no longer matter (as we already have our death entry, no matter if
the thread is gone now or not).
* The fibo_load_image test now works as expected (only tested with low numbers
yet, though - the mean testing comes later (first comes functionality) :-))
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19758 a95241bf-73f2-0310-859d-f6bbb57e9c96
some signals could go to some group when a negative value was passed in.
This actually fixes bug #702 where SoundPlay obviously does a kill_thread(-1)
at the end (which accidently killed all userspace applications, including the
input_server, app_server, ...).

alarm, or 0 if there isn't any.
* setitimer() now also sets the previous timer values correctly, so that
alarm() and ualarm() now return the correct values as well - this fixes
the test fork_9-1 failing at alarm().

a waitpid() can no longer succeed; this fixes the occasional fork 3-1 test failures.

it waited for a specific child), as B_RELEASE_ALL opened up a race condition between
looking for an existing death entry, and waiting for the dead children semaphore.
Now we're counting all waiting threads for teams and groups separately.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18543 a95241bf-73f2-0310-859d-f6bbb57e9c96
wait_for_child() hanging less probable - there is a general problem with
this code, though, as we need to have a dedicated free counter for the
semaphore to remove all race conditions.
* Also, test fork_3-1 still sometimes fails because the thread is still
available to the public for a short time, even after its death entry
has been collected.
* Added a TODO in the code for these issues.

let them eat death stack entries: after setting the next thread state to
THREAD_STATE_FREE_ON_RESCHED, interrupts were enabled again, which could
cause the thread to be rescheduled before having called put_death_stack().
This fixes bug #434.
* Note that the above change pretty much reverts revision 7865 that was supposed
to fix interrupt problem on thread exit (patch by Jack Burton almost 2 years
ago, that's how long this problem existed!).
* Made get_death_stack() and put_death_stack() symmetrical in that they don't
change interrupts. Also pulled out rescheduling from put_death_stack[_and_reschedule]()
and put it back into thread_exit2().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17652 a95241bf-73f2-0310-859d-f6bbb57e9c96
* As suggested by Korli, the signal is now encoded in the "reason" field of
wait_for_child().
* waitpid() now sets the status passed in so that the signal can be read out
(but it still doesn't do it's full job).

as stated in the BeBook - this fixes bug #458 as Tracker directly compared
with that error code.

instead of sending a signal.

* _user_wait_for_thread() was not interruptible before, ie. Control-C wouldn't
work.

time of the idle thread as a measure, we now compute the CPU activity on
each thread switch - the time the CPU worked is the total of user and kernel
time a thread spent during its quantum.
Unlike before, this mechanism works correctly on SMP machines. I hope this
works as expected :)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16193 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added syscalls _kern_set_cpu_enabled() and _kern_cpu_enabled().
* scheduler.c::sRunQueue::tail was not maintained at all; changed sRunQueue to
be a simple thread pointer instead of a struct thread_queue.
* Turns out we're monitoring CPU activity incorrectly when we've got more
than one CPU.
* Renamed the global CPU array from "cpu" to gCPU.

The test application lets run a thread at the highest priority that calls
yield all the time - the system stays responsible when it runs, so it seems
to work fine :)
Changed the malloc implementation to use _kern_thread_yield() instead of
snoozing.
We should think about making this call public, too.

enqueueing a thread to the run queue.
This mechanism is now used for the thread priority boost on semaphore
release. Also, those threads are no longer made real time threads, they
now get a temporary priority of B_FIRST_REAL_TIME_PRIORITY - 1.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16165 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added a thread priority column to the thread list.
* Added "realtime" command that lists all real-time threads.

them apart (this even saves a pointer from vm_virtual_map to its address space)
* aspace -> address_space
* vm_create_address_space() did not check if creating the semaphore succeeded
* Removed team::kaspace - was not really needed (introduced a new vm_kernel_address_space()
function that doesn't grab a reference to the address space)
* Removed vm_address_space::name - it was just a copy of the team name, anyway,
and there is always only one address space per team
* Removed aspace_id - the address space is now using the team_id
* Some cleanup.

threads listed by team ID. Also, the thread's team is now printed in the list as
well.
Minor cleanup (renamed "t" to "thread" where appropriate).

Extracted scheduler_init() from start_scheduler() (which is now called scheduler_start()).
Moved scheduler related function prototypes from thread.h to the new scheduler.h.
Cleanup.

Moved time calculation to team_remove_team().

having the thread lock held and interrupts disabled.
Cleaned up the signal handling code, and fixed some minor bugs with blockable
vs. non-blockable signals.
thread_debug_info was using uint64 for signals sets instead of sigset_t.

it will exit directly to have the same behaviour as in user space (where it doesn't
return to the caller, since signals are handled before returning to user space).

Simplified parsing the ID (no need to differentiate between hex and decimal, if
we do both anyway).

Replaced all dprintf() calls from the kernel debugger with kprintf() calls.

was another thread waiting for the death stack semaphore.

Renamed the idle thread/stack to start with 1 instead of 0 (first idle thread will
be called "idle thread 1").
Minor cleanup.

_user_receive_data() will now longer pass B_CAN_INTERRUPT to receive_data(),
but B_KILL_CAN_INTERRUPT - this should fix the problem Stefano experienced
with this function, even if I couldn't reproduce it.
