is perfectly okay on x86 anyway, but should be moved into the arch stuff).

* user_debug_break_or_watchpoint_hit() into separate functions for
break- and watchpoints. The one for breakpoints gets another parameter
which indicates whether the breakpoint was a soft- or hardware
breakpoint. This info is also sent to the debugger.

of a signal.
* Added sigaction_etc(). It's just a sigaction() for which the thread
in question can be specified.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11704 a95241bf-73f2-0310-859d-f6bbb57e9c96
not to be notified.
* Added debugger commands for setting/getting of thread signal ignore
masks and signal handlers.
* Renamed user_debug_fault_occurred() to a more correct
user_debug_exception_occurred(). It no longer sends a `stopped' message,
but the new one dedicated to exceptions. Additionally the number of the
signal is supplied that will be sent, when the thread continues (without
indicating to ignore the event).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11703 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added _kern_image_relocated() and _kern_loading_app_failed(), which
are invoked by the loader to provide the kernel with more info.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11689 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented _user_wait_for_debugger().
* Reworked a few bits to ensure that after a remove_team_debugger() or
after requesting a debugger handover the debugger doesn't get any more
messages.
* When the debugger is removed or dies, the debugged threads should now
cleanup their debug info and continue, instead of waiting at their
debug port forever.
All the new features are not tested. Will happen, when gdb will be
debugged.

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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11621 a95241bf-73f2-0310-859d-f6bbb57e9c96
we only have 3 debug registers available for break-/watchpoints.
* Added definitions for debug status register DR6. Reordered DR7 defs to
ascending order. Added definitions for the EFLAGS flags we need.
* Added arch_thread_debug_info structure and related definitions.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11525 a95241bf-73f2-0310-859d-f6bbb57e9c96
needed to get the topmost user iframe. Added i386_get_user_iframe() for
exactly that purpose.
* Added reinitialization of user debugging for the new thread when
switching the context.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11523 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the parameter for restoring the FPU state const.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11522 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added event callbacks for break- and watchpoints and single stepping.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11520 a95241bf-73f2-0310-859d-f6bbb57e9c96
debug infos.
* Added function for setting the CPU state.
* Added functions for setting break-/watchpoints.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11507 a95241bf-73f2-0310-859d-f6bbb57e9c96
by the team lock, but by a lock in the structure. This is necessary
since we can't acquire the team lock while thread switching, for then the
thread lock is already held.
* Added support for single stepping and break-/watchpoints.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11503 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed SIGKILLTHR from BLOCKABLE_SIGS.
* Made header C++ safe.
* Added function is_kill_signal_pending(), returning true, if a
SIGKILL[THR] is pending for the current thread.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11487 a95241bf-73f2-0310-859d-f6bbb57e9c96
convenience.
* Added/implemented callbacks for almost all missing debug events (team,
thread, image creation/deletion, exceptions/faults, signals).
* The debugger can now specify how to deal with the event that stopped an
event (ignore or handle signals, exceptions/faults).
* Implemented B_DEBUGGED_THREAD_GET_WHY_STOPPED debugger message.
* The cpu_state is now passed to the debugger with
B_DEBUGGER_MESSAGE_THREAD_STOPPED notifications.
* Completed _user_debugger() implementation.

will also get syscall that the app_server has to call in order to update
the frame buffer configuration.

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
Removed *_create() and *_create_entry_ref() syscalls - they are now handled by
*_open() and *_open_entry_ref() calls which get another parameter for the permissions.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11204 a95241bf-73f2-0310-859d-f6bbb57e9c96
link member in the element class. Usually more comfortable for structs.
* Added Add() method as synonym for Insert().
* Made fGetLink member static to save memory in objects using it.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11188 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added resolve_mount_point_to_volume_root() version for external use
(by the node monitor).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11159 a95241bf-73f2-0310-859d-f6bbb57e9c96
<disk_device_manager/KDiskDeviceUtils.h> into <util/AutoLock.h>.
Added instantiations for recursive locks (moved from vfs.cpp) and
mutexes.

to userland applications. A userland server (probably the registrar) will
register as the server responsible for delivering the messages. The
messages are passed to it via shared memory.
The advantage over sending the messages directly will be, that they won't
need to be dropped, if the receiver port is temporarily full.
Currently only the kernel side is implemented. Completely untested yet.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10983 a95241bf-73f2-0310-859d-f6bbb57e9c96
append-only and hence has very compact storage and a comparatively small
footprint implementation. Can be used for kernel->userland messaging.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10958 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also renamed children_next|prev to siblings_next|prev as I was confused by the former.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10671 a95241bf-73f2-0310-859d-f6bbb57e9c96
The driver settings are put into the kernel_args memory section and
copied on kernel startup.

be located in the "file_cache" directory - this might or might be changed later.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10602 a95241bf-73f2-0310-859d-f6bbb57e9c96
modules to use their module name directly.
Also introduced a whole range of reserved syscall functions in case we want
to add some more.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10458 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added new vfs_get_vnode() that actually grabs such a ref.
vfs_get_vnode_cache() now fills a vm_cache_ref instead of a void pointer.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10430 a95241bf-73f2-0310-859d-f6bbb57e9c96
Introduced new arch_vm.h ("public" arch headers have the arch_ prefix).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10384 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added real _user_exit_team() syscall (it was previously incorrectly mapped
to _user_exit_thread()).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10325 a95241bf-73f2-0310-859d-f6bbb57e9c96
Some of the remaining ones would be candidate for the standard Errors.h.
