* Extended the debugger message for B_DEBUGGER_MESSAGE_HANDED_OVER by the
causing thread.
* Also send B_DEBUGGER_MESSAGE_HANDED_OVER to the debugger to which the team
was handed over. The message will be the very first one the debugger gets
from the team in question.
* Some harmless refactoring (added thread_hit_serious_debug_event()).

* Added debugger commands to resolve usb_ids to pipes.
* Adjusted the physical memory allocator to be usable in a slimmed down mode
when running inside the kernel debugger.
* Implemented USB keyboard support for KDL through a kernel debugger add-on.
* Added kgetc() and made use of it where previously individual methods were used
to ensure that reading characters always goes through the kernel debugger
add-ons and the other methods.
This has some preconditions to meet though:
1) The keyboard must be in the boot protocol (currently the case but needs to
be revisited once we have a full usb_hid).
2) The keyboard must be attached to a UHCI root port (i.e. not use EHCI or OHCI,
also not through hubs unless those are USB 1.1).
3) the usb_hid driver has to be opened for this to work. This means that for the
time between initializing USB and when usb_hid is opened by the input_server
there is no keyboard support.
Also note that this has no way of detecting hot-plug, meaning that you can't
re-attach your USB keyboard from the hub to the root port once in KDL.
On the bright side of things, since this is a non-destructive mechanism it is
possible to enter and leave KDL without loosing the USB state.
Tested OK in QEMU, not tested on real hardware yet, will see in a few minutes.

It causes the interrupt handler to be inserted at the very end of the list
instead of at the top. It is intended to be used as a workaround when a
interrupt handler cannot know if it actually handled the interrupt. This
should never be used by native drivers. Also if we know that the result is
not valid because of this flag we won't disable the vector in case we count
many unhandled interrupts as those numbers are then unreliable.
* Moved B_NO_LOCK_VECTOR to be a private flag as well.
* Made the interrupt handler list a simple manually maintaned singly linked list
instead of the doubly linked one used with insque and remque as it greatly
simplifies things for such an easy use case and is more compact.

overheard that they looked too ninety-ish.
TODO: The code behind this is work in progress. The basic idea
is to extract all drawing code into a new class BControlLook,
of which there is a global instance be_control_look, instantiated
in InterfaceDefs.cpp. At the moment, all the old drawing code is
still there, and the usage of be_control_look is inside if-bodies
checking the instance against NULL. In another words, by not
instanitating be_control_look, you can revert back to the old look.
BControlLook's job is to provide reusable methods for drawing
certain types of frames, backgrounds and labels, so that application
developers can make controls that re-use the same drawing code
as built-in controls and adopt to changes made there. I have added
the notion of "borders". Each of the frame drawing methods can be
made to draw certain borders only, which is supposed to help when
controls shall visually attach. This feature is not fully explored
at all ATM.
TODO: Update BColumnListView header view and BStringItem text
spacing. Update other apps where it makes sense to use BControlLook.
For the moment, only Tracker and LaunchBox are updated. More...
NOTE: The new look is not very radically different, so that existing
apps do not immediately look too ugly or out of place.

Renamed BGradient::color_step to BGradient::ColorStop
as it's called everywhere else. Also renamed BGradient::gradient_type

complete and yet inactive code to accelerate vertical gradients
(bypassing AGG for this special case).

* Remove the previous method of applying the overlay by flags. In the future the
overlay can just be mounted as a filesystem layer. This is probably how layers
were intended to work in the first place.
* Move the filesystem module info and filesystem name from the fs_mount to the
fs_volume structure. Filesystem layering is done by having multiple layered
volumes and we want to be able to have a different fs per layer.
* Adapt VFS code to this move.
* Implement mounting layered filesystems. Specifying multiple filesystems
separated by a colon on mount will cause the layers to be set up and the
corresponding filesystems to be mounted at that layer.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29199 a95241bf-73f2-0310-859d-f6bbb57e9c96
node. That is needed for a layered filesystem to be able to construct a full
fs_vnode out of a volume/inode pair.
* Adapt places where get_vnode is used. Sadly this is a C API and we can't just
use a default NULL for that argument.
* Introduce a flag B_VNODE_WANTS_OVERLAY_SUB_NODE that can be returned in the
flags field of a fs get_vnode call. A filesystem can use this flag to indicate
that it doesn't support the full set of fs features (attributes, write support)
and it'd like to have unsupported calls emulated by an overlay sub node.
* Add a perliminary overlay filesystem that emulates file attributes using files
on a filesystem where attributes aren't supported. It does currently only
support reading attributes/attribute directories though. All other calls are
just passed through to the super filesystem.
* Adjust places where a HAS_FS_CALL() is taken as a guarantee that the operation
is supported. For the overlay filesystem we may later return a B_UNSUPPORTED,
so make sure that in that case proper fallback options are taken.
* Make the iso9660 filesystem request overlay sub nodes. This can be fine tuned
later to only trigger where there are features on a CD that need emulation
at all.
If you happened to know the attribute file format and location you could build
an iso with read-only attribute support now. Note that this won't be enough to
get a bootable iso-only image as the query and index support is yet missing.

* Replaced the use of offsetof() for structs that aren't PODs. Add a
offset_of_member() macro to util/khash.h because that's what it's used for
in our cases.
* Change the signature of add_debugger_command()/remove_debugger_command() on
GCC > 2 to avoid the depricated conversion from string constants to char *.

This is a very welcome addition.
* There are a few issues, and maybe questionable decisions (like the dependence
on ACPI), but I see no reason why it shouldn't be added in its current form

old invalid user listeners yet, though (ie. if a team dies).
* Implemented userland network monitor functions.
* Added a few notifications to the network stack, even though this part isn't
complete yet (especially notify_interface_changed()).
* Added optional debug output to the notifications module.

broke everything. If the added item has no chance to calculate it's height,
_RecalcItemTops() won't work of course. Whatever this was supposed to fix,
there has to be a correct way.
* Override BView::SetFont() to update all the items. I remember wanting to
implement this, that's why I refactored a _FontChanged() method, but I
obviousy never did...
* Moved the AttachedToWindow() and FrameMoved() implementations to a more
logical position in the file.

* The DesktopSettings class is now using that to send the new
AS_SYSTEM_FONT_CHANGED message to all windows.
* The ServerWindow now propagates font changes to its decorator, causing it
to update its drawing. That means changing the bold font in the "Fonts"
preferences application will instantly change all window titles.
* Factored out a _RebuildAndRedrawAfterWindowChange() out of several Desktop
methods, simplifying some code.
* The DefaultDecorator no longer calls _DoLayout() twice (through SetLook()),
but instead calls the new _UpdateFont() method now also called by
FontsChanged(), and SetLook().
* BWindow::GetDecoratorSettings() now also includes "tab frame" BRect with the
exact footprint of the tab, allowing apps to know the size of the tab to
position itself accordingly.

(this only caused the actual stream to share the same position with the
BBufferIO, something you just cannot rely on when using buffered I/O).

the per-root-image breadth-first sorted image array. Instead we have a
per-image hook function to resolve the symbols. The default function
uses the sLoadedImages list directly, which is breadth-first sorted
anyway. There's also a BeOS function for old-style symbol resolution
and one for add-ons, which lacks a proper implementation yet (just
uses old-style ATM).
* Made the dl*() functions POSIX compliant:
- dlopen() does no longer use load_add_on(), but loads the object as a
library. It also properly supports a NULL name, now -- the previous
"_APP_" work-around did only work, if this soname was set on the
program (unlikely for programs using this API).
- Implemented RTLD_{GLOBAL,LOCAL}.
- dlsym() looks up symbols properly now, i.e. not just in the given
image, but breadth-first for an actual image or in load order for
the global scope. It also supports the not-quite POSIX RTLD_DEFAULT
and RTLD_NEXT extensions. Our RTLD_NEXT finds more symbols than in
Linux (also in later dlopen()ed libraries), but that should be fine.

instance.
* TextView.h and PoseView.h are now a little cleaner.
* InterfaceDefs.cpp now deletes gWidthBuffer in _fini_interface_kit_().

Obviously it kind of defeats the purpose of having WidthBuffer neatly tucked
away in the BPrivate namespace, but Haiku should run NetPositive, I guess.

* 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.

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().

* 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.

* 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)

BGradientDiamond, BGradientConic and BGradientRadialFocus
new Interface Kit classes.

* app_server/View can convert a BGradient layout to screen

* 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

in struct stat.
* Instead, I followed Marcus' great idea and added a compatibility check in
the runtime loader: now, R5 binaries (also shared libraries) are detected,
and they get special versions for stat(), fstat(), and lstat() that return
the smaller stat struct.
* However, I've disabled (in src/system/libroot/posix/sys/stat.c) using the
larger stat field for now, as this breaks some of our optional packages.
So until we rebuild them all, this shouldn't be enabled.

arch_vm_aspace_swap().
* The x86 implementation does now maintain a bit mask per
vm_translation_map_arch_info indicating on which CPUs the address
space is active. This allows flush_tmap() to avoid ICI for user
address spaces when the team isn't currently running on any other CPU.
In this context ICI is relatively expensive, particularly since we map
most pages via vm_map_page() and therefore invoke flush_tmap() pretty
much for every single page.
This optimization speeds up a "hello world" compilation about 20% on
my machine (KDEBUG turned off, freshly booted), but interestingly it
has virtually no effect on the "-j2" haiku build time.

buffer format, the buffer can now also contain other events than just
stack traces. ATM these are only references to the image events
(created/deleted). Therefore we no longer have to flush the profiling
buffer after such an event, since the debugger can exactly match the
samples. Since we couldn't flush when the profiling timer hit while the
thread was in the kernel, that wasn't working that well anyway.
"profile -f" fails to translate stack trace addresses only very rarely,
now.

Also pass it a flag whether the boot volume is where the boot loader
pre-loaded the modules from.
* module_init_post_boot_device() changes the pre-loaded module image
paths to normalized boot volume paths, now. Got rid of the code in
register_preloaded_module_image() which tried something like this.
* Changed module image ref counting. A referenced module has single
reference to its image, which is released when the module becomes
unreferenced.
* get_module() for a reference module will not try to re-get and re-set
the module's image anymore. That could lead to a similar module (from
different paths) being loaded at the same time. A module from a new
file can only be loaded when the old one has been put completely.
* Simplified B_KEEP_ALIVE module handling a bit. When the module is
initialized, we add another reference, which we'll never free. Thus
the module remains loaded without special handling. Removed
module_image::keep_loaded. A B_KEEP_ALIVE module remains referenced
and thus its image remains referenced, too.
* Removed module::file, a cached path to the module's image. An
optimization that wouldn't work with multiple root directories for
modules (/boot/beos/..., /boot/common/...) or when module files were
moved. get_module() does now always search the image file, when the
module is still unreferenced. This should be a bit slower than before,
but I didn't notice any difference in VMware at least. If it turns out
to be a problem we could introduce a more intelligent cache that stays
up to date by using node monitoring.

* Extended the profiling API by an option to record a variable number of
samples per tick. The stack depth is used as a maximum.
* Added new option "-f" to the "profile" tool. When specified it
increments the hit counts of all symbols in the full available caller
stack. I.e. the resulting hit counts will approximate the total time
spent in each function or any function directly or indirectly called

functions only what time has actually been spent in them.

* The class calculates a minimum width now, which is based on the line height,
this may also fix the bug with the small text inputs in the Pe Find window.
* Added TODOs about implementing GetHeightForWidth(), which may be a good idea
when a BTextView is used as non-editable informative text in an interface,
and one wants to make sure that the entire text is shown.
* Replaced the call to _Refresh() in Draw(), which recalculates all the line
breaks for no reason with _DrawLines() again. The TODO mentioned that text
will be drawn without drawing the background first, but maybe this is a
relict from times where Draw() was invoked directly? At least I cannot see
any negative consequences, and this should be much more efficient.

side effects...<crosses fingers>)

* Adjusted used files systems accordingly.
* BFS::Stream::GetName() was broken. It accessed the small data region
which wasn't loaded, since BFS::Stream derived from bfs_inode, which
is a variably-sized structure with the small data region at the end.
Changed that to a ref-counted, shared member instead.
* Implemented RootFileSystem::GetName().
* Added Directory::GetPath() to get a full path of the directory or an
entry.

buffer during a timer event that interrupted a kernel function: We do
now flush the buffer as soon as it is 70% full, *if* we didn't interrupt
a kernel function. When the buffer runs full and we still haven't hit a
user function, we drop the tick. The number of dropped ticks is recorded
and sent to the debugger with the next update message.
Reverted the previous partial solution (the temporary disabling of
profiling while in debugger support code).

is created or deleted (or exec*() has been invoked). The counter is
sent with several debugger messages.
* Track the image event counter that is used when samples are added to
the profiling buffer. If the current team counter differs, we flush
the buffer first (sending an update message to the debugger), so that
the debugger has a chance to match the addresses to the correct images.
* Disable profiling for a thread while it runs in the debugger support
code. This fixes potential deadlocks which could occur when a
profiling timer event occurred that would require the buffer to be
flushed while the thread was just sending something to the debugger or
waiting for a command. As it turns out, this is not sufficient either,
since we should never try to flush the buffer when the timer event
occurred in the kernel, since the thread might hold a lock that the
debugger thread could try to acquire. Will implement a more general
solution later.

BTextView classes:
* Declared the directly used BTextView helper classes as private BTextView
classes and changed all affected files.
* Realized that Tracker's BPoseView was (accidentally?) using what used to
be _BWidthBuffer_. It had declared it's own class with the same name and
same members/size in headers/private/tracker/TextViewSupport.h, but the
implementation was nowhere to be found. I can only explain this that
the BTextView implementation was then actually linked and used. But the big
problem was that it was used without locking (unlike in BTextView)! When
many Tracker windows opened during system startup or later and they happened
to each request characters not yet in the cache, I imagine things could have
gone bad and corrupted memory. Anyways, since I can see the usefulness of
the cache, BPoseView uses BTextView::WidthBuffer on purpose now. And I moved
the locking inside BTextView::WidthBuffer::StringWidth().
* Adjusted InterfaceDefs.cpp accordingly.
* TODO: Move subsequent classes into BTextView namespace as well, ie derived
classes that BTextView doesn't directly know about. All stuff in src/kits/
inteface/textview_support/
* Added preliminary and not yet implemented layout friendly BTextView
constructors.
* I will try to handle the insets imposed by BTextView::fTextRect a bit
differently when used inside the new layout management framework. For this,
I added BTextView::SetInsets() and GetInsets(). SetInsets() doesn't do
anything yet.
So far, everything seems to work still... ;-)

* We can't enable interrupts in an interrupt handler. Instead we use the
newly introduced callback feature, which notifies the debugger right
before returning from the interrupt.
* We didn't indicate that the profiling buffer was full and that the
thread shouldn't be profiled ATM. Therefore it could happen that it
was profiled while trying to notify the debugger that the profiling
buffer was full, resulting in a deadlock. Introduce a respective flag
in the thread debug structure.

be tracked to the kernel, which then counts the hits, an area is
passed to kernel in which the hits are recorded. When the area is
full, the debugger is notified. For some reason that part doesn't work
yet -- the whole system freezes when waiting for a reply.
* Reorganized the profile tool code a bit. For one with respect to the
changed API, but also to prepare tracking of image creation/deletion.

* wait_for_timer() now detects if it has been called from within the timer
execution thread, and will return in error instead of waiting for itself
forever. This fixes bug #2682.

various system information.
* Implemented retrieving some VM stats via this call.
* The VM now maintains a page fault counter, and sets system_info::page_faults
accordingly.
* Added a (pretty simple) "vmstat" command line app.
* Minor cleanup.

* The layout friendly constructors don't need to mess with the control size.
* The layout friendly constructors can use the respective BControl constructor.
* Refactored some duplicated code.
* Removed duplicated GetFontHeight() calls.

doing a lot of these things the same way as BMenuField are already doing.
Perhaps a private helper class could be refactored from these two controls
to avoid duplicating a lot of this code, although there are a few subtle
differences here and there.
These changes make a BTextControl behave properly in the layout management
frame work, in case CreateLabelLayoutItem() and CreateTextViewLayoutItem()
are _not_ used to layout the BTextControl.

user "unsets" the explicite max size.

* Removed unused fClean member
* Got rid of fSkipSetFlags member by simply calling the BView::SetFlags()
directly where fSkipSetFlags was supposed to prevent the custom
implementation.
* Added some debugging facilities.
* Used the layout friendly constructors of BControl where appropriate.
* Used B_FOLLOW_ALL for the child text input, it should be more correct.

VMware this doesn't produce very good results though. In my tests I only
got twice as many hits as with 1 ms, although it should be roughly ten
times as many. Might work better on real hardware.

still pretty much work in progress.
* Introduced init_thread_debug_info() which is used instead of
clear_thread_debug_info() when the thread is created. The latter
requires former initialization.
* user_debug_thread_deleted() is now already invoked in thread_exit(),
not in the undertaker.

* The most important fix is that in BMenuField::_ValidateLayoutData(),
divider was calculated, but then never used. If the menu field was not
using the layout management, it should take the existing fDivider into
account, but never did. This caused #2728.
* Added some tracing that helped me debug this.
* Fixed a bunch of layouting inconsistencies. It will also improve some
unnecessary resizing of the menu bar.
Will test all of this some more. But in the test app I do have, the BMenuField
works more like in BeOS now.

scroll bar does not have the standard width or height.

interfaces, endpoints and generic descriptors.
* Add getter for active interface index and simplify the count operation as
it isn't misused to also get interface descriptors anymore.
* Refactor out some common code into helper functions.
* Adapt the USBKit to the changed/new interface.
* Change how alternate interfaces are exposed by USBKit by providing normal
BUSBInterface objects for alternate interfaces that can easily be examined
and used.
* Make BUSBInterface class aware of its alternate index and use the alternate
aware usb_raw functionallity to build the endpoint and descriptor lists.
* Add ActiveAlternateIndex() to find out what alternate is currently active.
* Style cleanup of the USBKit classes, use std::nothrow everywhere and check
all allocations. Simplify some code by removing optimization where the benefit
is questionable.

ACPI still needs memory then.

* Imported radix bitmap tree implementation from FreeBSD and adjusted it
for Haiku.
* Make use of the radix tree in the swap support implementation instead
of using simple bitmaps. This will allow for faster swap slot
allocations. ATM Haiku doesn't benefit that much, since we always
allocate single pages, but that will change eventually.

unscheduled was incorrect.
* Introduced _kern_analyze_scheduling() syscall. It requires scheduler
kernel tracing to be enabled. It uses the tracing entries for a given
period of time to do a similar analysis the "scheduler" debugger
command does (i.e. number of runs, run time, latencies, preemption
times) for each thread. Additionally the analysis includes for each
thread how long the thread waited on each locking primitive in total.
* Added kernel tracing for the creation of semaphores and initialization
of condition variables, mutexes, and rw locks. The enabling macro is
SCHEDULING_ANALYSIS_TRACING. The only purpose is to provide
_kern_analyze_scheduling() with more info on the locking primitives
(the name in particular).
