(that was part of the problem of bug #702).
* Fixed send_signal_etc() when you called it with a pid_t of zero: the signals should
go to all teams in the calling team's group, not only to the team (for -1, we do
the same for now).
* Made team_get_process_group_locked() public, and rewrote send_signal_etc() to use
it.

hash. This also allows them to stay valid after the group leader died when there are
other teams left in it. This closes bug #1.

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.

inserts the item before, and not after the given element (that's probably
what you expected anyway).
* Added ReverseIterators.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18307 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added an Insert() variant that can insert an element behind another one.

arch dependent code (they will be removed as soon as someone else
asks for these interrupt lines).
* Added an interrupt driven keyboard handler to the kernel that uses
this technique. As a result, you can now press F12 to enter the kernel
debugger before the input_server has been started, and Control-Alt-Delete
should reboot the system (actually I did not test the latter yet).

the path is stored, there, though.

* 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).

scan job in the calling thread).
* KDiskDeviceManager::InitialDeviceScan() now runs synchronously, so that
get_boot_partitions() doesn't need to do this ugly wait hack.
* KDiskDeviceManager::CreateFileDevice() can now run synchronously as well, which
fixes a deadlock in fs_mount() - note, mounting file devices still doesn't work,
though as Haiku's BFS doesn't allow this right now.

when called with interrupts turned off, get_memory_map() will now call the new
vm_translation_map_ops::query_interrupt() call.
Under PPC, this is trivial (at least right now), but on x86 we need to make sure
we have access to the page table entry, ie. we need to create an area that points
to its own page table entry, so that we can map in the page table entry containing
the address we're looking for. It's not really nice, feel free to come up with
a cleaner solution :-)

always call all handlers in this case, but we still try to return the correct
return code (ie. B_HANDLED_INTERRUPT and B_INVOKE_SCHEDULER).

systems a chance to know if they have locked already.
This fixes a locking problem in BFS where one thread tried to acquire two read
locks (where someone else trying to acquire a write lock would have caused a
dead lock).

function, and added a vfs_disconnect_vnode() for other kernel components.
* devfs_unpublish_device() can now optionally make use of this call.
* Fixed the type check of devfs' unpublish_node().

information to identify the boot volume - if we want to be able to map all BIOS
drive IDs to the disks in the system, we need to do this always, though.
* Forgot to commit the updated disk_identifier.h in the last commit...
* Removed the unused dumpBlock() function from devices.cpp.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16892 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Adapt other sources where needed (the boot loader's RootFileSystem still
used the old implementation).
* Implemented RootFileSystem::Rewind().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16889 a95241bf-73f2-0310-859d-f6bbb57e9c96
loader): it now supports holes between segments, and accepts any segment order.
* Renamed elf.c to elf.cpp and fixed warnings.
* Renamed elf_image_info::dynamic_ptr and eheader to dynamic_section and elf_header.
* Some cleanup.

now on the amount of memory installed in the system. Ie. if you have only
128 MB the kernel heap will be only half in size.
* Minor cleanup in vm_page.c, renamed some variables to match our style guide.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16838 a95241bf-73f2-0310-859d-f6bbb57e9c96

area.

That buys some more time before switching to a slab allocator :)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16767 a95241bf-73f2-0310-859d-f6bbb57e9c96
and a timeout.
* _user_wait_for_thread() was not interruptible before, ie. Control-C wouldn't
work.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16654 a95241bf-73f2-0310-859d-f6bbb57e9c96
of that list.
* Added a vfs_free_unused_vnodes() function that calls the low memory handler
directly.
* create_sem_etc() now calls the above function in case there are no semaphores
available anymore; this usually frees up to 2 semaphores per node (one from
the cache if there is a file cache attached, and eventually one from the
file system).

or vm_cache_ref couldn't be created, instead of cleaning up and returning
an appropriate error.
* vm_cache_ref_create() no returns a status_t instead of the vm_cache_ref
(as that's part of the vm_cache anyway).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16602 a95241bf-73f2-0310-859d-f6bbb57e9c96
that put one or more full paths on the stack before, which could cause some
problems under certain conditions.
* Cleaned up KPath, ie. use size_t instead of int32 where appropriate, added
license.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16585 a95241bf-73f2-0310-859d-f6bbb57e9c96
(mounting still only works from the Terminal).
* Shuffled functions in node_monitor.cpp around to clearly differentiate between
private, private kernel, and public kernel functions.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16575 a95241bf-73f2-0310-859d-f6bbb57e9c96
before another one in the list.
* The video modes in the boot loader are now sorted (by resolution, larger
resolution comes first). Doubled entries are automatically removed; this
fixes bug #192.

the device manager is initialized. For x86 it does nothing, but
for PPC it searches for a supported interrupt controller and
remembers it for later use.
arch_int_{enable,disable}_io_interrupt() are implemented as
well as handling of external exceptions (aka as I/O interrupts).
We'll see later how well that works.

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.
