778aa3bf62 transfer_io_request_data(): There was some confusion about the isWrite
parameter and request->IsWrite(). The parameter means whether we want to
write to the request's I/O buffer (therefore renamed it to writeToRequest),
while request->IsWrite() indicates whether the request is a write request.
One can only write to a read request's buffer and vice versa.
IOBuffer::LockMemory() also wants to know whether the request is a write
request, not whether we want to write to the memory.

931d8b07e8 * Reverted r32216 (by mmlr): it's not a good idea to access a variable on the
stack after that has just been changed, and does not contain the data one
  would assume.
* This fixes the leaking the vm_translation_map_arch_info objects, and thus
  bug #4957.

returned by open() aren't suitable for directory iteration and because checks
  have to be performed (like whether this is a directory at all and whether the
  user has read permission).
* Added __create_dir_struct() for the attribute, index, and query open
  functions to use instead.

7249de5e61 * Changed the affine scheduler to have more or less the same characteristics
as the BeOS scheduler. This makes MediaPlayer playback much better, as high
  priority threads could lose their quantum to a worker thread twice in a row
  with 4% probability before.
* I did not yet change the simple scheduler as well yet; maybe this isn't the
  final one either.

a0439d88df * Adjusted thread priorities of several system services based on a mail from

6242fd5977 * Added the possibility to debug latency issues with spinlocks.
* When DEBUG_SPINLOCK_LATENCIES is 1, the system will panic if any spinlock is
  held longer than DEBUG_LATENCY micro seconds (currently 200). If your system
  doesn't boot anymore, a new safemode setting can disable the panic.
* Besides some problems during boot when the MTRRs are set up, 200 usecs work
  fine here if all debug output is turned off (the output stuff is definitely
  problematic, though I don't have a good idea on how to improve upon it a lot).
* Renamed the formerly BeOS compatible safemode settings to look better; there
  is no need to be compatible there.

8665c30ace That was not such a good destruction order in the error case. As the scheduler
accesses the scheduler data inside the thread structure, freeing it first lead
to a crash when a thread couldn't be created.

13ce48d922 * Moved dprintf_args()/debug_puts() guts to a new dedicated private function
debug_output().
* Added a second buffer to be used when interrupts are turned off, otherwise
  dprintf_args() will now use a mutex guarded buffer to fill with vfprintf() -
  the actual sending to the outputs still needs the spinlock, so things only
  slightly improved.
* Moved private functions into the private section of the source file.

3530c3eb6b * Reimplemented the insane _get_next_thread_info() which previously just
iterated over all known thread *IDs* with interrupts disabled.
  Now it iterates over the team's thread list (going from back to front, since
  new threads are added at the front of the singly linked queue).

  reproduce a certain bug - and then wondered why ProcessController would
  take several seconds to open its windows until it passed through more than
  8 million IDs... :-)

f28dd36b82 * The alphabet is obviously hard, moved some tracing defines at their
(hopefully) correct place.
* It seems to be even harder to understand basic locking primitives: when you
  think about it, it shouldn't surprise you that conditional variables never
  return B_WOULD_BLOCK. This fixes gdb again.
* Added tracing support to the ports subsystem.
* get_port_message() will now resize the port heap if needed (but will also
  take timeouts into account while doing so, more or less). The initial port
  space is 4MB (as before), the growth rate is the same, and the system wide
  limit is arbitrarily set to 64 MB (all swappable). A team limit has been set
  to 8 MB, but is not enforced yet. Since ports are using up address space in
  the kernel, those seems to be proper limits.
* This also fixes a strange, and rare lockup where the mouse cursor would still
  move, but everything else would basically hang, but look perfectly normal from
  KDL on the first look. As recently happened on Brecht's laptop, and debugged
  by mmlr and me: the cbuf space got used up when lots of windows wanted to
  redraw after a workspace switch. The app_server wouldn't answer anymore to
  client requests, but thought it would have done so, as LinkSender::Flush()
  doesn't care if it got a B_NO_MEMORY (the ports will now block until memory
  is available if possible, so that should not be a problem anymore).
* Improved "port" KDL command, it now also prints the messages in the port.

e8885f2097 Basically rewrote the ports subsystem to use:
* its own heap allocator instead of cbuf - this makes cbuf superfluous, and I
  therefore removed it from the kernel. The heap is swappable, so lifts the
  kernel's resource usage a bit. In the future, the heap should grow as well;
  right now it should be at least as good as before.
* it no longer uses spinlocks, but just mutexes now for better scalability - it
  was not usable with interrupts turned off anyway (due to its semaphore usage).
* it no longer uses semaphores, but condition variables.
* Needed to move the port initialization to a later point, as swappable memory
  wasn't usable that early.
* All ports test are still passing, hopefully I didn't mess anything up :-)

6bb413270b The allocation size wasn't updated on an area based realloc that would still
fit into the existing area. In that case further reallocs could then assume the

usable from C. Everything's currently exposed in shared/private/locks.h but I

PageWriteTransfer. This makes the transfer accept virtually contiguous pages,
where the offset is contiguous on either end of the current transfer, but where
the pages aren't physically contiguous. It will then add seperate iovecs for
these pages (32 at max right now). This reduces the number of IO requests
generated and allows for optimizations down the IO path (like in the physical to
virtual mapping case for example).

32e2b6a118 Provide a way to directly request virtual vecs from an IOBuffer. If the buffer
is virtual already it just returns the vecs directly, if it is physical it takes
over the task of virtualizing the vecs either using vm_map_physical_memory_vecs,
if there are multiple vecs or more than one page, or falls back to page wise
mapping if mapping fails or is not needed. In the best case, scattered physical
pages are mapped into one linear virtual buffer so that subsystems operating on
virtual memory only get a single vector and can then burst read/write.

1af7d11504 * Rework page writing to combine page writes where possible. For now the pages
are required to be physically contiguos, which should be reworked to put them
  into seperate iovecs. Still this manages to combine a great deal of page
  writes into larger bursts already. Reduces the amount of IO requests being
  scheduled (and greatly benefits media where page wise writes are slow when
  they are accessed through a non-IOScheduler path, i.e. USB mass storage until
  that is properly implemented).
* Abstracted per page page writing tasks into a PageWriteWrapper class.
* Abstracted per transfer page writing tasks into PageWriteTransfer class which
  formerly was the PageWriterCallback.
* Use both classes from the PageWriterRun and from
  vm_page_write_modified_page_range to remove code duplication.
* Adjusted synchronous VMAnonymousCache::Write() to cope correctly with larger
  iovecs and more than one iovec. It assumed that there was exactly one page per
  vector previously.
* Introduced MaxPagesPerWrite() and MaxPagesPerAsyncWrite() to VMCache to allow
  a cache to specify restricitions. VMAnonymousCache does restrict the max pages
  to 1 for WriteAsync right now as I didn't feel like reworking that one to cope
  with non single page writes just yet.
* Pulled out PageWriteTransfer methods for better readability.
* Some typo fixes.
