possibility to initialize the AutoLocker without locking the object even
if it is unlocked yet. Especially in loops Lock()/Unlock() come handy
when an otherwise constantly hold lock needs to be unlocked for a short
time.
I suppose we should move the kernel utils AutoLocker implementation
to headers/private/shared, and drop the less powerful ObjectLocker.

{set,clear}_debugger_{break,watch}point(), allowing to set/clear break

the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.
We clear the arch specific team and thread debug infos now, when a new
debugger is installed, thus clearing break- and watchpoints.

* Removed send_notification().

* vm_clone_area() now respects the source area's wiring and inherits it. This
should fix bug #1055.
* vm_cache::type is now duplicated in vm_area::cache_type - this allows looking
it up without having to lock a vm_cache_ref; this also solves a locking bug
in vm_unmap_pages() in this regard.

Basically, there was a pretty subtle race between the cpus in main where if the main cpu released the AP cpus and then before the AP cpus had a chance to run the boot cpu started creating the main thread (which causes smp ici messages to be created) the system would livelock, where the boot cpu waited forever for the AP cpu to acknowledge the ICI (for a TLB flush when creating the kernel stack).
Added smp_cpu_rendezvous(), used to synchronize all the cpus to a particular point, and used it a few times in main().
While i was at it i fixed another race that'll probably never happen, but what the hey. Make sure the kernel args are copied into kernel space by the main cpu before letting any other ones use it.

* Made publish_vnode() available in userland. For old style FS add-ons
publish_vnode() is used when they request a new_vnode(). The semantics
of new_vnode() changed considerably in Haiku, but publish_vnode()
seems to do pretty much what the old new_vnode() did.
* The UserlandFS hosted RamFS begins to work under Haiku. It runs pretty
soon out of memory though (under vmware with 256 MB) and node
monitoring is broken ATM.

old interface is completely done in userland ATM.
It becomes more and more obvious that we probably need to provide
the kernel add-on with a bit more information about what the client FS
interface supports in the first place, so we can save unnecessary trips to
the userland. Opening/closing attributes for a FS using the old style
interface could be handled completely in the kernel add-on, for instance
(even if we lose a bit of accuracy wrt to open modes etc.).

need via library libuserlandfs_beos_kernel.so. Fine-tuned the legacy headers
so they can by used by the the kernel interface emulation code as well as by
the add-ons. This is actually a bit hacky, since we build everything in the
Haiku build environment and thus mix these old headers and Haiku's.

* vm_area and vm_page now have a new field "mappings" where they will store lists
of vm_page_mapping structures. vm_page::ref_count is gone, as it's no longer
needed (it was never updated correctly, anyway).
* vm_caches now have a type field, ie. CACHE_TYPE_RAM for anonymous areas - this
makes the stores a bit less independent, but is quite handy in several places.
* Added new vm_map_page() and vm_unmap_pages() functions to be used whenever you
map in or unmap pages into/from an area. They don't do much more than handling
vm_page::wired_count correctly right now, though (ie. B_LAZY_LOCK is now working
as expected as well).
* Moved the device fault handler to vm_map_physical_memory(); it was not really
used as a fault handler, anyway.
* Didn't notice Ingo's changes to the I/O space region broke lock_memory(). It
now checks the type of the area that contains the memory, and doesn't lock
anymore if not needed which solves the problem in a platform independent way.
* Implemented lock_memory() and unlock_memory() for real: they now change the
vm_page::wired_count member to identify pages that shouldn't be paged out.
* vm_area_for() now uses vm_area_lookup() internally.
* Fixed various potential overflow conditions with areas that reach 0xffffffff.
* Creating anonymous areas with B_FULL_LOCK no longer causes vm_soft_fault()
to be called, instead, the pages are allocated and mapped (via vm_map_page())
directly.
* Removed the _vm_ prefix for create_area_struct() and create_reserved_area_struct().
* Fixed a bug in vm_page_write_modified() that would not have enqueued pages that
failed to be written to the modified queue again when needed.

* Renamed them, made everything static besides vm_allocate_early() (previous
vm_alloc_from_kernel_args()) which now allows you to specify a different
virtual than physical size, and therefore makes vm_alloc_virtual_from_kernel_args()
superfluous (which isn't exported anymore, and is now called allocate_early_virtual()).
* Enabled printing a stack trace on serial output on team crash - it doesn't hurt
for now, anyway.
* Cleanup.

* Renamed a few parameters of the FS module hooks:
- *file in the attribute functions to *vnode
- v to vnode
- I could barely restrain myself from renaming the "_*" parameters. I
understand this marks return parameters, but I'd prefer a nicer prefix
or suffix (that doesn't makes you think this is a private/internal
identifier) like "out", "ret", "return", "result", or something similar.
I'd also like to propose renaming {read,write}_link() to
{read,write}_symlink(). Er, and do we need write_link() at all?

The first use is to let the kernel decide what the preferred syscall mechanism is at boot time and copy the
appropriate user space code there. Can be used for routines the kernel can decide best how to use (memcpy, some
timing routines, etc).

the new cpuid stuff was apparently exacerbating an existing problem where various bits of low level
cpu code (specifically get_current_cpu) weren't really initialized before being used. Changed the
order to set up a fake set of threads to point each cpu at really early in boot to make sure that at
all points in code it can get the current 'thread' and thus the current cpu.
A probably better solution would be to have dr3 point to the current cpu which would then point to the
current thread, but that has a race condition that would require an int disable, etc.

Now two complete tss structures exist within the per-cpu structure. Instead
of having to create a seperate area per each one, initialize them in place.
Also, the old mechanism to getting all of the cpus to get initialized was
subtly broken, but still managed to work. Now, just force all the cpus to
initialize at boot, which makes the actual swapping of esp0 somewhat simpler.

* recursive_lock_unlock() now returns a void to mirror it's counterpart better;

* switch_sem(), and release_sem() now don't do anything anymore in kernel startup
mode.

for one quantum wasn't really a good idea, as this could get quite expensive for the thread
(depending on the system load, it might have taken a long time until the thread was scheduled
again, no matter what priority it was).
Also, calling thread_yield() in a loop would have taken 100% CPU time.
Now, we sort the thread into the queue as with any other thread, but we'll ignore it once.
This now guarantees an actual context switch, as well as a much fairer rescheduling policy
for threads calling that function.

at boot, per cpu, detect the cpu, pull down all the relevant cpuid bits and
save them into the per-cpu structure. Changed most of the code scattered here
and there that reads the cpuid to use a new api, x86_check_feature, which looks
at the saved bits.
Also changed the system_info stuff to read from these bits.
While i was at it, refreshed all the bits to be current.

this fixes bug #1005. As a result, the Disks icon will now appear in file panels
when you change that setting with a panel open.
* _ObserverList is now in the BPrivate namespace (and renamed to ObserverList).
* its BHandler map is now only temporarily used for handlers that do not belong to
a looper yet; when BHandler::SendNotices() is called, they will be transferred
into the BMessenger map.
* Invalid messengers are now removed from the map when encountered.
* Added TODO comments about a possible reference counting if a handler is added
twice to a list (right now, this will be ignored).
* All {Start|Stop}Watching() methods are now more or less safe to be used in low
memory situations (adding some items to the map can still throw an exception...).
* Renamed BHandler::InitData() to _InitData().
* Some refactoring and cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20029 a95241bf-73f2-0310-859d-f6bbb57e9c96
* we now always flush the TLBs after having unmapped some pages.
* vm_soft_fault() could traverse to a source cache while it was being collapsed
by vm_cache_remove_consumer() - this is now no longer possible as the latter
marks the cache as busy when doing so, and the former now tests this flag and
locks the cache (via the new fault_acquire_locked_source() function).
* if fault_acquire_locked_source() fails with B_BUSY, the current cache is locked
again, and tested again for the page - as it might have been moved upwards to it
with the destruction of its former source.
* The cache delivering the page for vm_soft_fault() is now locked until the end;
it can no longer go away before having actually mapped the page into the area.
* This also fixes the issue where pages would get lost as vm_soft_fault() put the
page in the active list, no matter if its cache still existed.
* Also, we now keep a reference of to a cache in case a dummy page is inserted; this
makes again sure that it doesn't go away during the execution of vm_soft_fault()
(which could even add this page to the free list...).
* divided vm_soft_fault() into several smaller functions which should make it much
more readable.
* Added a "cache_chain" KDL command that dumps the whole chain until the bottom
when giving a pointer to a vm_cache as parameter.
* now usually call vm_cache_acquire_ref() before map_backing_store(), even though
it shouldn't be really needed (I added it for debugging purposes).
* Some minor cleanup.
* NOTE: a major problem still persists: when removing a vm_cache, it's possible
that some of its pages are still mapped, and there is currently no mechanism
to get rid of these mappings! I've added TODO comments into vm_cache.c where
appropriate.

process group. This fixes bug #996.
* As a result, the process group stuff and wait_for_child() got much simpler;
get_death_entry() and update_wait_for_any() could go away completely.
* If a team goes away, all of its children are now "reparented" to the kernel team,
instead of the team's parent - this follows common implementations (and POSIX if
I understand it correctly), but not BeOS anymore. The OpenGroup Base says this
about this topic: "If a parent process terminates without waiting for all of its
child processes to terminate, the remaining child processes shall be assigned a
new parent process ID corresponding to an implementation-defined system process."
* We wait too long in wait_test_4 which at least puts us on par with Linux; see

with PostMessage() in case the message queue is full.
Some notes:
* for synchronous replies, we don't use this mechanism yet, but it could be
extended to do that as well.
* the code looks so complicated because we need a way to access the looper's
queue without locking it (to prevent deadlocks); like Dano's solution, I've
abused BTokenSpace to store a BDirectMessageTarget with a BHandler.
* we also need to decouple the lifetime of a looper's queue from its target,
as we cannot lock the looper, and therefore, can't guarantee it stays valid
as long as we're accessing it outside of BLooper.
* init_clipboard() now needs to be done after the global constructors have
been called - since sending messages now needs gDefaultTokens to be initialized.
Since this is done per image, it shouldn't cause any troubles, though.
* some minor cleanup, removed unused _msg_cache_cleanup_() and friends.

someone else.
* There were several locking bugs in the VM code; since cache_ref::cache can
change, we must not access it without having the cache_ref locked.
* As a result, map_backing_store() now requires you to have the lock of the
store's cache_ref held.
* And therefore, some functions in vm_cache.c must no longer lock the cache_ref
on their own, but require the caller to have it locked already.
* Added the -s option to the cache/cache_ref KDL commands: it will only print
the requested structure, and not its counterpart (useful if accessing one
structure results in a page fault, as was possible previously).

Made the following changes from the version I got from Eric:
* made BppForSpace() in DriverInterface.h inline to remove some warnings
* renamed driver source files to lower case.
* removed Be Inc. copyright from kernel driver as I couldn't see anything coming
from Be Inc. there - correct me if I was wrong, Eric.
* Minor other changes like added missing header guards.
* The README provided in the main directory is only included in the accelerant
directory.

turned off - accessing userland memory. Now, arch_thread_enter_userspace() does that
job, and as a result, may also fail.
* dump_thread() now directly prints the info of the current thread when used without
argument (rather than iterating the thread list to look for the current thread).
* If arch_thread_init_tls() fails upon thread creation, the function will now return
an error.

them to commit substantially less memory (we we're committing about 40 MB (!) too much
after a complete system boot). This means you'll run out of memory less likely now.
* fill_area_info() no longer filters out kernel protection flags - we may want to keep
filtering them when called from userland, though, dunno.
* Added new debugger command "avail" which shows how much memory has been committed, and
how much is regarded as free space.

to other kernel components.
* wait_for_thread_etc() will now search the team's death entries in case the
thread is already gone; also resume_thread() is now done later, and its return
code will no longer matter (as we already have our death entry, no matter if
the thread is gone now or not).
* The fibo_load_image test now works as expected (only tested with low numbers
yet, though - the mean testing comes later (first comes functionality) :-))

in addr_range.h to add ranges to the arrays. This fixes the crashing bug reported
by Larry Baydak.
* Added some more exported functions to kernel_args.cpp (prototypes are in addr_range.h).
* TODO: let the PPC/OpenFirmware implementation use those as well.

app_server for this; added a new AS_IS_FRONT_WINDOW command for this.
For example, clicking on the menu bar to bring windows to front in FFM mode
does work now.

* _ContrainPoint() was broken as it could never change the point it was supposed
to contrain.
* MouseDown() no longer sends a notification message automatically (only if it
changed something)
* MouseMoved() and synchronous MouseDown() will now only send modification messages
if something actually changed (not for every mouse update).
* After key presses, the invokation message is only sent when the value changed.

* Unified UTF8CountChars and UTF8ToLength and removed the latter
* Rewrote UTF8CountBytes to use the more safe algorithm from UTF8CountChars
* Removed the unsafe count_utf8_bytes() function
This should fix bug #839. Marcus can you please review?

app_server. I added it at the end. Feel free to move it to a better spot, if
there is one. Note that putting it in the middle with require recompiling a lot
of things.

* In grayscale mode, the AccelerantHWInterface now sets the palette correctly.
* HWInterface now has a fVGADevice set by AccelerantHWInterface which will be used
to talk to the VESA driver.
* Completed planar blitting for all 4 planes; we now have a perfect 16 color
grayscale mode when you choose "Standard VGA mode" in the boot loader with
an unsupported graphics card (such as in Qemu).

* Added an "owner" field that stores the team which created the socket (for netstat only);
we would need a different storage for SIGURG if we ever want to support that.
* Improved netstat address output: now prints "*" instead of INADDR_ANY.

of BFont. You can BFont::SetFalseBoldWidth(float) a width on a
BFont object, and it will cause the glyph shapes to be run through
an AGG "contour converter" so that they become thicker or thinner.
IIRC, this is commonly referred to as "false bold". The "width" value
is the distance in pixels that the new glyph outline will be offset
from the original outline.
It would be nice if someone could look at my change to View.h with
regards to the B_FONT_ALL flag.

Unless such hardware is not serving this screen...

within the library - theoretically, this mechanism could be extended to
turn the compatibility layer on and off based on the images that call the
functions (allowing to mix R5 and BONE network add-ons in a single executable).
This change fixes R5 networking apps such as Vision, and NetworkTime (both
now seem to work fine under Haiku).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19431 a95241bf-73f2-0310-859d-f6bbb57e9c96
commented the insertion of the attribute name in patterns in the case of a string attribute
notify_probe_by_file chooses a module based on a bus specific suffix
dm_register_child_device has a parameter to optionally check the support for the node
added scanning of bus devices after the boot filesystem is mounted
fixed dm_rescan, locking was misbehaving
fixed SYSTEM_DRIVER_REGISTRATION definition
added B_DRIVER_MAPPING attributes for PCI and ACPI devices:
%vendor%_%device% for PCI, hid_%hid% and type_%type% for ACPI
moved acpi_device_module_info definition to public ACPI.h

by the TCP implementation for its reorder and retransmit queues.
* The ipv4_fragment is no longer needed, as we can use the above field there
as well - this saves one extra allocation per received fragment.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19369 a95241bf-73f2-0310-859d-f6bbb57e9c96

there is some unfortunate code duplication in AppFileInfo,
because it cannot use BMimeType/BNode alone to retrieve icons,
now it works closer to the code in BIconUtils, this fixes
R5 icons not displaying for other icon sizes
* implemented a bilinear scaling function, I don't know if
it is very fast, but I hope it is reasonable. Now that I
see the results though, I wonder if R5 icons should be
scaled with nearest neighbor instead...
* corrected a small bug in the icon format stuff...
7 bit coords are -32-+95, not 96
* improved comment for BIconUtils function
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19302 a95241bf-73f2-0310-859d-f6bbb57e9c96

drawing (I accidentally broke it in the previous commit).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19264 a95241bf-73f2-0310-859d-f6bbb57e9c96

it enables to iterate the device manager tree from userland
* the listdev tool is now using it: it's still incomplete as it only dumps nodes and attributes

and cancel_notification() functions.
* Completey dropped the old select code, as well as any R5 compatibility stuff. If
we ever need it again, it's still in SVN history.
* The socket module was put in uninit_driver() for no reason.
* Minor cleanup.

is not supposed to be called for accepted sockets, only for those created via
a call the userland socket() function.
* Renamed net_socket_module_info::socket() to open_socket() to make this distinction
a bit clearer.

- Implemented fixed dividers support for laptop panel refresh rate.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19209 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added some missing result checks, mostly for allocations.
* Fixed a wrong precendence with the ?: operator
* Some minor cleanup.
* Renamed sBufferModule to gBufferModule - the header expects it to be a global,
so it should be named like one.
