416458e9c4 * Added nothrow to the new operator because otherwise the C++ compiler
will not accept if the allocator returns NULL and crashes instead
  (ie. not compiling in tracing would have crashed if some module tried
  to use it).
* Added total entries count to the KDL command output.
* Fixed computing the start index of the KDL command.

  Nice to use if you don't have serial output or need something that doesn't
  slow down the system as much.

a52c1759ac Fixed two bugs in the vnode disconnecting code found by bonefish+mmlr:
* vfs_disconnect_vnode() did not put away its vnode reference.
* disconnect_mount_or_vnode_fds() did always throw the current working
  directory of all apps on the same mount away, even if only a specific
  vnode should have been disconnected.

34b3b26b3b Merged branch haiku/branches/developer/bonefish/optimization revision
23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
  it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
  the assembly handler which now uses a jump table to call C functions
  handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
  interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
  rare events (signals, user debug enabling/disabling) on the
  common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
  retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
  the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
  common functions (currently memcpy() only). They are used in the
  kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
  member offsets in assembly code.

Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
  (caused by refactoring and introduction of "call" debugger command).

3e5b9076f9 * Fixed (or rather, worked around) a deadlock in the VM: when a file was
resized but still had dirty pages to be written back, 
  vm_cache_resize() (which is called with the inode lock being held)
  deadlocked with the page writer.
* Now, I reintroduced busy_writing: it'll be set by everything that
  writes back pages (vm_page_write_modified(), and the page writer),
  and will be checked for in vm_cache_resize() - other functions are not
  affected for now, AFAICT.
* vm_cache_resize() will clear that flag, and the writer will check it
  again after it wrote back the page (which will fail when it's outside
  the file bounds), and if it's cleared, it will get rid of the page
  (if the file has been resized again in the mean time, writing it will
  succeed then, and we'll keep the page around).

bcb71f00e8 * My last change to vm_page.cpp made an existing bug much more likely to
appear: when freeing a modified page, it wouldn't have a cache
  anymore, but set_page_state_nolock() depended on it.
* To work around this, I added a vm_page_free() function, which the
  caches that free modified pages have to call (but others may, too).
  It will correctly maintain the sModifiedTemporaryPages counter in case
  the cache has already been removed.

a function in the stack trace (only works reliably when a stack frame

  of stack_trace() to be used by show_call() as well.

4accd841c7 * Fixed a big bug in common_file_io_vec_pages(): vecOffset was not correctly
set when the first chunk of the file could be read in directly, causing it
  to read data to a wrong place in the buffer.
* Reading in the first chunk directly would have also only worked if vecIndex
  and vecOffset was 0 when calling the function.
* Applied the fs_shell changes in file_map to the kernel version as well (the
  constructor already worked correctly, though).

b938008fe1 * Update the PAUSE macro from "rep; nop;" to "pause;" which is the same bytecode wise but more readable
* Insert the pause op in all spin wait loops (as macro for platform independent sources or as inline assembly on x86 only files)
* Fix some warnings with tracing on and extended some output
* Minor cleanups here and there

The pause instruction is implemented since P4 systems but is fully backwards compatible (it's a no-op prior to P4). According to Intel specs it reduces performance penalties as memory order violations can be avoided. Also power consumption is reduced. Most of all this will be beneficial to hyper-threading systems as it frees resources to the other logical processor when one logical processor executes a fast spinning loop.

fb431b443b * vfs_unmount() can now safely be called from the kernel (fs_unmount() still
tried to access the uninitialized vnode in that case).

  will then be unmounted automatically.

  impossible, it was NULL once.

device geometry.
* If SetTo() reports no media, and GetGeometry() fails, the device geometry

* KDiskDeviceManager::_ScanPartition() no longer unmarks the partition busy;
  this is now done by the caller, and done independently from the outcome of
  _ScanPartition(). This also fixes the problem that devices with no media
  were never marked unbusy (and thus were ignored subsequently).

3d268eda3d * Extracted file_map API out of the file cache - it's now an optional service
that can be used by file systems.
* Changed the way the file cache works: instead of reading/writing to the
  underlying device directly, it can now be used for any data source, ie.
  also network file systems.
* As a result, the former pages_io() moved to the VFS layer, and can now be
  called by a file system via {read|write}_file_io_vec_pages() (naming
  suggestions are always welcomed :-)). It now gets an FD, and uses that to
  communicate with the device (via its fs_{read|write}_pages() hooks).
* The file_cache_{read|write}() functions must now be called without holding
  an I/O relevant file system lock. That allows the file cache to prepare the
  pages without colliding with the page writer, IOW the "mayBlock" flag can
  go into the attic again (yay!).
* This also results in a much better performance when the system does I/O and
  is low on memory, as the page writer can now finally write back some pages,
  and that even without maxing out the CPU :)
* The API changes put slightly more burden on the fs_{read|write}_pages()
  hooks, but in combination with the file_map it's still pretty straight
  forward. It just will have to dispatch the call to the underlying device
  directly, usually it will just call its fs_{read|write}_pages() hooks
  via the above mentioned calls.
* Ported BFS and FAT to the new API, the latter has not been tested, though.
* Also ported the API changes to the fs_shell. I also completely removed its
  file cache level page handling - the downside is that device access is no
  longer cached (ie. depends on the host OS now), the upside is that the code
  is greatly simplified.

cfe386c2d5 * read_into_cache() and write_to_cache() both did not compute the number of
needed pages correctly, and would also not read/write enough in case the
  offset didn't start at 0 resulting in undetected short reads/writes. It's
  amazing how many bugs can be hidden in a few lines of code.
* Fixed a bug that might have been the cause for bug : when the last part
  of the write did not end on a page boundary, the last page had to be read
  first, but that was done from the wrong offset. Also, if only parts of that
  page could be read (because the file size didn't span over the whole page)
  the remaining parts needed to be cleared.
* The cache_funcs were always called with the same value for numBytes and
  bufferSize so I've eliminated the former.
* Large reads now also bypass the cache in case of low memory, large writes now
  also only bypass the cache in that case, following Ingo's suggestion.
* Fixed compilation with debugging turned on.

the same pages over and over.
* Increased the priority of the page writer a bit, so that it is higher than
  the one of the page daemon.
* Added a sModifiedTemporaryPages counter to let the page_writer decide how
  many pages are there to write back (temporary pages would go to the swap file
  and are only written back when memory is low).
* In case there are more than 1024 modified (non-temporary) pages around, the
  page writer will constantly write out pages, not only when being pushed.
* The page writer now temporarily always leave out temporary pages (as long as
  we don't have a swap file).
* Shuffled functions around a bit.

  free and clear lists empty and would therefore rightfully panic

  that the caller has marked the concerned partitions busy, hence we can
  (read-)access them without needing a lock. The module interfaces will
  will be changed to take advantage of the fact as well. The methods take a
  disk_job_id instead of a KDiskDeviceJob* now, though I haven't quite
  decided, whether we need it at all or just want to add a special
  handling in the cases where notifications during the operation make
  sense.
* Reimplemented the disk device write support syscalls (save
  _user_move_partition() for which other module hooks are needed). They
  call the KDiskSystem methods, now.

99d0c19e37 whenever a node has already a child, it means a driver has already attached to this node
for this reason, we don't add such a node in the list of nodes to be scanned
this fixes the bug

fcfbb8aa6c libprefs.so uses the private _klock_node_() syscall, and even loops until it
returns success - since this stub always returned failure, this prevented all
apps using that library (like Gobe Productive) from running.
It now calls the Haiku equivalent _kern_lock_node(), and Gobe now runs fine!
This closes bug .

45ae0aa1aa It's not a good idea to write back large files while keeping the vnode busy.
The low memory handler now has two passes which should help there; however, it
might also accidently remove recently used vnodes, too. We could mark the clean
ones in some way if that turns out to be a problem.

e544dd5915 * Fixed a possible dead lock between the kernel daemon and the DDM; the media
status checker now only tries to lock the manager, it won't wait anymore.
* Added MediaChanged() and UpdateMediaStatusIfNeeded() methods to KDiskDevice.
* KDiskDeviceManager::_CheckMediaStatus() now uses these new methods; it should
  no longer detect removed media more than once :-)
