scheduler_set_thread_priority(). Setting the thread priority was the
only situation in which it was used.
* Renamed scheduler.cpp to scheduler_simple.cpp.
* The scheduler functions are no longer called directly. Instead there's
an operation vector now, which is initialized at kernel init time.
This allows for picking the most suitable scheduler for the machine
(e.g. a non-SMP scheduler on a non-SMP machine).

* Added a layout friendly constructor - it's not so nice to use, though, since
the original one already doesn't get a BRect (we just don't need the
resizing mode, and have to set the B_SUPPORTS_LAYOUT flag).
* Refactored size/frame computation a bit.
* Cleanup.

* Turned the checks for all those macros to "#if"s instead of "#ifdef"s.
* Introduced macro KDEBUG_LEVEL which serves as a master setting.

added vm_memcpy_from_physical() and vm_memcpy_physical_page(), and
added respective functions to the vm_translation_map operations. The
architecture specific implementation can now decide how to implement
them most efficiently. Added generic implementations that can be used,
though.
* Changed vm_{get,put}_physical_page(). The former no longer accepts
flags (the only flag PHYSICAL_PAGE_DONT_WAIT wasn't needed anymore).
Instead it returns an implementation-specific handle that has to be
passed to the latter. Added vm_{get,put}_physical_page_current_cpu()
and *_debug() variants, that work only for the current CPU,
respectively when in the kernel debugger. Also adjusted the
vm_translation_map operations accordingly.
* Made consequent use of the physical memory operations in the source
tree.
* Also adjusted the m68k and ppc implementations with respect to the
vm_translation_map operation changes, but they are probably broken,
nevertheless.
* For x86 the generic physical page mapper isn't used anymore. It is
suboptimal in any case. For systems with small memory it is too much
overhead, since one can just map the complete physical memory (that's
not done yet, though). For systems with large memory it counteracts
the VM strategy to reuse the least recently used pages. Since those
pages will most likely not be mapped by the page mapper anymore, it
will keep remapping chunks. This was also the reason why building
Haiku in Haiku was significantly faster with only 256 MB RAM (since
that much could be kept mapped all the time).
Now we're using a different strategy: We have small pools of virtual
page slots per CPU that are used for the physical page operations
(memset_physical(), memcpy_*_physical()) with CPU-pinned thread.
Furthermore we have four slots per translation map, which are used to
map page tables.
These changes speed up the Haiku image build in Haiku significantly. On
my Core2 Duo 2.2 GHz 2 GB machine about 40% to 20 min 40 s (KDEBUG
disabled, block cache debug disabled). Still more than factor 3 slower
than FreeBSD and Linux, though.

* Renamed _BDeviceAddOn_ to DeviceAddOn, and put it into the BPrivate namespace.
* Moved the DeviceManager functionality into the AddOnManager - this also
solves a locking issue, as BInputServerDevice::Control() was called in the
context of the DeviceManager before.
* The AddOnManager now uses the BPathMonitor to monitor the devices that
BInputServerDevices ask for - this greatly simplifies the code.
* Got rid of TList.h, and use ObjectList.h instead.
* Added PathList class that has a list of paths with reference count, used by
DeviceAddOn and the AddOnManager.
* DeviceAddOn got an actual implementation that lives in InputServerDevice.cpp.
* Added an experimental BInputServerDevice::AddDevices() that could be used
instead of recursing over devices manually. It replaces the functionality
that was found in the DeviceManager before (this was done implicitely for
all monitored devices).
* Greatly cleaned up and simplified the AddOnManager.
* Also fixed lots of potential errors/leaks when things go wrong.
* Removed the extra locker in AddOnManager - its BLooper lock is now used
instead.
* Replaced PRINT()/PRINTERR() macros in the AddOnManager with TRACE(), and
ERROR(), both now use debug_printf().
* Hopefully this fixes the problem that I don't have keyboard under VirtualBox
from time to time.

* check if locking the offscreen window succeeds before calling delete on it
* don't return offscreen windows in CountWindows and WindowAt (works now as on R5)
fixes ticket 1522, 1591, 1946, 2318 and propably more
While creating an BBitmap in BApplication the bitmaps window looper would
be added to the applications gLooperList, thus calling Quit() on that window
and later delete on a stale window pointer in BBitmaps dtor. The Lock() check
would fix the problem, but tests on R5 have shown that BApplication hides the
offscreen window in CountWindows() and WindowAt().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28236 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Introduced flag "invoke_scheduler" in the per CPU structure. It is
evaluated in hardware_interrupt() (x86 only ATM).
* Introduced SMP_MSG_RESCHEDULE_IF_IDLE message, which enters the
scheduler when the CPU currently runs an idle thread.
* Don't do dprintf() "CPU x halted!" when handling a SMP_MSG_CPU_HALT
ICI message. It uses nested spinlocks and could thus potentially
deadlock itself (acquire_spinlock() processes ICI messages, so it
could already hold one of the locks). This is a pretty likely scenario
on machines with more than two CPUs, but is also possible when the
panic()ing thread holds the threads spinlock. Probably fixes#2572.
* Reworked the way the kernel debugger is entered and added a "cpu"
command that allows switching the CPU once in KDL. It is thus possible
to get a stack trace of the thread not on the panic()ing CPU.
* When a thread is added to the run queue, we do now check, if another
CPU is idle and ask it to reschedule, if it is. Before this change, the
CPU was continuing to idle until the quantum of the idle thread
expired. Speeds up the libbe.so build about 8% on my machine (haven't
tested the full Haiku image build yet).
* When spinlock debugging is enabled (DEBUG_SPINLOCKS) we also record
the spinlock acquirer on non-smp machines. Added "spinlock" debugger
command to get the info.
* Added debugger commands "ici" and "ici_message", printing info on
pending ICI message respectively on a given one.
* Process not only a single ICI message in acquire_spinlock() and other
places, but all pending ones.
* Also process ICI messages when waiting for a free one -- avoids a
potential deadlock.
* Mask out non-existing CPUs in send_multicast_ici(). panic() instead of
just returning when there's no target CPU left.

* Added a new class BAffineTransform, currently in the BPrivate namespace
and the inofficial "shared kit".
* Extended BPolygon to be transformable by a BAffineTransform.
Thanks a lot!
Minor fixes by myself:
* The class accidentally still derived from agg::trans_affine.
* Added then missing comparator operators.
* Swapped the BPoint* and count arguments of Apply(), since that seems
to be the more common order in the other Be API.

* Fixed a general problem with respect to overriding of the reserved
virtual function slots: instead of statically invoking the method
that corresponds to the reserved slot on the class that contains the
slot, we now invoke the virtual Perform() method. Perform() then dispatches
the method invocation to the "proper" class, i.e. the highest class in the
hierarchy that actually implements the requested method.
This fixes a crash in apps that use liblayout's MSlider class and
should fix one or other spurious bug with old apps or libraries, too.
* added new header folder 'binary_compatibility' that contains files that
define the method codes and data structures required by Perform()
* looked for and implemented all used reserved virtual slot functions to
invoke Perform() where necessary or to pass on the method call statically
(for slots that were already maintained by Be)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28124 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented BGradient, BGradientLinear, BGradientRadial,
BGradientDiamond, BGradientConic and BGradientRadialFocus
new Interface Kit classes.
* Implemented all the (AGG-based) backend necessary in
the app_server to render gradients (Painter, DrawingEngine)
* app_server/View can convert a BGradient layout to screen
coordinates.
* Added BGradient methods of the Fill* methods in BView.
* Implemented a test app and added it to the image as a
demo.
* Adopted Icon-O-Matic and libs/icon in order to avoid
clashing with the new BGradient class. Re-use some
parts where possible.
Awesome work, Artur! Thanks a lot. Now a more modern
looking GUI has just become much easier to implement! :-)
TODO:
* Remove the need to have gradient type twice in the
app_server protocol.

prevent B_MOUSE_MOVED message from being stolen that are important for
detecting transit changes. The point is that some apps (like Tracker) are
shooting themselves in the foot because they steal mouse messages via
GetMouse() in one place, but then rely on sane transit values in another
place. The way it works now, the view in question may get notified of the
same mouse moved coordinate twice, once via GetMouse() and once via
MouseMoved().
