d5b30a2548 * As Marcus correctly pointed out indirectly, the bitmask for
ide_mask_sector_count_48, and ide_mask_LBA_*_48 were all wrong.
* Using the high byte in LBA48 mode should work now, too (wasn't written
  to the IDE controller before, but that shouldn't have been a problem yet with
  today's disks).

9a42ad7a77 When switching to a kernel thread we no longer set the page directory.
This is not necessary, since userland teams' page directories also
contain the kernel mappings, and avoids unnecessary TLB flushes. To make
that possible the vm_translation_map_arch_info objects are reference
counted now.

This optimization reduces the kernel time of the Haiku build on my
machine with SMP disabled a few percent, but interestingly the total
time decreases only marginally. Haven't tested with SMP yet, but for
full impact CPU affinity would be needed.

  this doesn't work yet.

53892c92a0 * Replaced scheduler_remove_from_run_queue() by
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.

47c40a10a1 * Prefixed memset_physical() and memcpy_to_physical() with "vm_",
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.

23debb05d0 * Rewrote InputServerDevice.h header.
* 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.

d751323939 * reintroduce member fOffscreen which got removed in r2917
* 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().

7ab39de989 * Removed unused SMP_MSG_RESCHEDULE ICI message.
* 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.

  to be the more common order in the other Be API.

39fbf5509b bonefish + zooey:
* 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)

991547ef6c Patch by Artur Wyszynski:
* 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.
* Refactor some parts of the patch to remove duplicated
  code (Painter, DrawingEngine).
* Adopt the BPicture protocol to know about BGradients.
* Review some parts of the BArchivable implementation.
