function has the old behavior. When false, it just calls the scheduler
without any priority adjustment or other stuff.

23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
the assembly handler which now uses a jump table to call C functions
handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
rare events (signals, user debug enabling/disabling) on the
common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
common functions (currently memcpy() only). They are used in the
kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
member offsets in assembly code.
Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
(caused by refactoring and introduction of "call" debugger command).

vfs_select.h, respectively moved most of it into the new kernel
private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
work pretty much like poll(), but also for semaphores, ports, and
threads.
* Removed the "ref" parameter from notify_select_events() and the
select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
is no longer needed. The FS interface select() hook still has it,
though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
pair, now. Added respective functions for semaphores, ports, and
threads.

* On exec() the new function thread_reset_for_exec() is called which clears the signals
and cancels an eventually set alarm. Both things weren't done before...
* Some minor cleanups.

the new cpuid stuff was apparently exacerbating an existing problem where various bits of low level
cpu code (specifically get_current_cpu) weren't really initialized before being used. Changed the
order to set up a fake set of threads to point each cpu at really early in boot to make sure that at
all points in code it can get the current 'thread' and thus the current cpu.
A probably better solution would be to have dr3 point to the current cpu which would then point to the
current thread, but that has a race condition that would require an int disable, etc.

and a timeout.
* _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 :)

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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16166 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.

time of the idle thread. IOW Pulse now works :-)
Renamed the idle thread/stack to start with 1 instead of 0 (first idle thread will
be called "idle thread 1").
Minor cleanup.

threadID parameter to spawn_kernel_thread_etc(). It's now possible to
set the ID of a new thread. Used in team.c to make team ID and the ID of
the main thread equal.
Fascinatingly the two added functions prompt my compiler to issue
`missing prototype' warnings, although those are obviously there. It would
be nice if someone could solve that riddle.

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).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11331 a95241bf-73f2-0310-859d-f6bbb57e9c96
a new thread_entry_func typedef in the kernel only. Unlike thread_func, it accepts
two arguments - that functionality is not exported to the user, though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8777 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed the thread/team syscalls to the new naming scheme.
Some other minor cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6867 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added new syscall for set_thread_priority().
Replaced the userland syscall snooze_until() with snooze_etc() (the latter
has to be exported to userland and realize snooze() and snooze_until()).
Cleaned the sources - scheduler functions now have the scheduler_ prefix.
Moved signal related stuff into ksignal.h (out of thread.h).
Replaced public kernel API with direct exports (i.e. resume_thread() instead
of thread_resume_thread()).
Removed the thread_create_XXX_thread*() calls, and replaced them with a
BeOS compatible set.
Made some fields of struct thread a bit prettier.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2569 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed lock.h to like those changes.
Moved the create_sem_etc() from the public OS.h to the private kernel only
sem.h, cleaned it up a bit.
gcc doesn't seem to like the "extern inlines" with -O0 -g, so I replaced
an inline function in thread.h with "static inline" (which it does always
like).
