* Scheduling analysis output:
- Sort the threads by total run time.
- Group the locking primitives a thread has waited on by common type
and name. E.g. all "I/O request finished" condition variables are
put in a single group. The sum wait time and wait count is printed
for the group, so it is easy to see how often and how long the
thread had waited for I/O.
- Both the groups and their elements are sorted by wait time.

operation length.
* IORequest: Added owner (IORequestOwner). Also added a SetUnfinished()
method, which is invoked by the I/O scheduler after all operations of
the request have been finished, but the request isn't done yet.
* Added debugger commands "io_request_owner" and "io_scheduler" printing
information for a IORequestOwner and IOScheduler object respectively.
* Implemented an actual I/O scheduling algorithm. It's a simple round
robin strategy (a queue per thread) with a unidirectional elevator
serializing the operations. ATM priorities are ignored, the bandwidth
isn't adjusted to the device, and there are TODOs all over the place.

* Simplified the subpixel related methods for the AGG "pixel format" template
interface, the ones for the solid cover simply pass through the existing
methods, so only one subpixel blending function is left which does the actual
work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
implements subpixel anti-aliasing for any generic AGG vector pipelines. It
is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
rotated, sheared or big enough fonts) depending on the global subpixel
setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
to InterfaceDefs.cpp where other such functions live. They are not related
to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
them to the Appearance preflet instead.
All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

the environment would crash on Haiku. Added a small test application that
just checks every one of those.
* Fixed env locking (in userland, you better check against B_INTERRUPTED).
* Made our code safe against an environ of NULL.
* There is now an additional sManagedEnviron that points to the environment
our code actually managed; whenever an application overrides environ, we'll
get aware of it with the next *env() function invocation, and will handle
it adequately.
* Added non-POSIX clearenv() function.

partially (e.g. due to hitting the end of file). The respective
classes have grown new methods and attributes to deal with that. The
"finished" callbacks have got additional parameters to indicate
whether the transfer was only partial and how much has been
transferred. Other callbacks and functions have a size_t* in/out
parameter instead of a simple size_t, now.
* vfs_{read,write}_pages() do now use the I/O request framework instead
of the underlying FS's {read,write}_pages() hooks (those should be
unused now). Furthermore they've got an additional "flags" parameter,
which is passed to IORequest::Init(), i.e. it allows to specify that
the given vecs refer to physical addresses.
* The file cache's read_into_cache() reads directly into physical
pages, now.
* Fixed bug in DoIO::IO(): The offset was not adjusted, so that all
pages were incorrectly transferred from/to the same location.
* Fixed broken subrequest scheduling loop head in
do_iterative_fd_io_iterate().
* Adjusted the test driver and implemented its io() hook. Using this
driver I/O requests are passed all the way from the VFS/VM to the
driver and through the I/O scheduler. It even seems to work. :-)
* Added missing const to the iovec* parameter of the IORequest::Init()
methods.
* Disabled some debug output by default. Added new optional debug
output.

small clipping holes to the TestView user clipping.
* Added a bunch of new tests. Here are some numbers from the test environment,
which is similar to running Haiku in VESA mode:
Horizontal lines per second:
Haiku: 192964.663 (117,7%)
ZETA: 163977.006
Vertical lines per second:
Haiku: 90109.985 (276.9%)
ZETA: 32538.458
Random lines per second:
Haiku: 7998.451 (23.1%)
ZETA: 34602.539
Random colored lines per second:
Haiku: 7976.437 (22.9%)
ZETA: 34788.247
Random clipped lines per second:
Haiku: 262.180 (2.5%)
ZETA: 10394.794
Clipped glyphs per second:
Haiku: 5911.526 (1.0%)
ZETA: 590508.726
Obviously the clipping performance is a punch in the stomache.

Something is still fishy though: Opening the dma_resources_test device
in DiskProbe, the wrong data is shown. do_io() seems to be invoked with
the correct physical address, vm_get_physical_page() succeeds, and after
memcpy() the correct data are in the virtual address it returned, but
db in the kernel debugger shows that the data in the physical page have
not been changed. When quitting DiskProbe the "page still has mappings"
assert is triggered for the page.

* Moved data buffer creation to a TestSuiteContext class.
* Added checks if the I/O operation does the correct thing, ie. reads/writes
the data to the right offset.
* Rearranged DMA translation: we now handle the partial write case correctly
(bounce buffer must always span over the whole block), and are able to join
adjacent bounce buffers together.
* The new _AddBounceBuffer() method also respects boundary and segment size
restrictions for bounce buffers.
* IOOperation now prepares the outgoing vecs/offset/length to contain the
right data for the current phase (partial read begin/end/do-all); it will
also make sure that the lengths of the vecs are of the same size than the
whole request.
* All tests are now passed, the I/O request implementation seems to be ready
for integration now.

More work on the I/O scheduler, more precisely mainly the DMAResource class:
* When splitting requests into operations, we're now able to flexibly mix
bounce buffer segments and the given physical vectors in a single
operation. This reduces the number of operations.
* Squashed several TODO and fleshed out more of the implementation.
* Added a test driver running unit tests. There are only a few tests yet,
but those pass.

get drawn into a window with random colors. With that one can for example add
code to the app_server or interface kit classes that push through rects or
regions to see what exactly is going on in drawing operations. Code examples
of how to use are at the top of the file. Has fixed window dimensions though
as I was lazy :-)

(or at least incompatibly) uses the user set clipping region when determining
whether or not to call Draw() on a view. Under BeOS when a some part of a view
is exposed it will always trigger a Draw(), even if the current clipping region
disallows drawing in the supplied update rect. Under Haiku however the view is
not considered for an update when the current clipping region does not
intersect with the newly exposed area.
Running this test app from the Terminal this behaviour can be seen. When
clicking inside the window a floating window pops up. When clicking again it
goes away and triggers a redraw. When hitting a key, a clipping region is set
that does not overlap with the floating window. After this clipping is set,
the view does not get any Draw() call anymore when the floating window goes
away.
This is the reason for the redraw issues in firefox, as firefox uses the
clipping region to constrain its asynchronous drawing, but does never reset
the clipping to NULL. As firefox just collects the update rects in Draw() and
then draws the contents itself, once the clipping region is set, many of the
Draw() calls don't get called and the interface parts are never redrawn.

infos (should all be defaults expect for a few).
This shows that with our default installation there are quite a few "condensed"
styles and also an "extra light" variation. The condensed ones should probably
get their own face flag. The "extra light" and other unhandled styles should
probably not be classified as a B_REGULAR_FACE as this could lead applications
to use them in a wrong way yielding unexpected results (i.e. firefox that
picks up the "extra light" style for it's interface font).

into the kernel:
* Added device_removed() function to the device level as well.
* A device_node now also tracks its published devices.
* Made the driver API more consistent with the device API; instead of the node,
they now get the driverCookie (so they now need to store the node themselves,
the driver cookie could be retrieved via the node).
Alternatively, one could either pass both, or have something similar to what
Ingo did for the file systems, ie. pass a structure that contains both
elements. Suggestions welcome.
* Implemented device node replacement when a better driver becomes available:
the new node (and its devices) is already published even though the old device
is still in use. The new device is B_BUSY until the old one is closed.
* Implemented an update cycle counter: this will prevent a device node from
being probed again, if there is no new driver since the last time; eventually
this will be moved into devfs, though.
* Driver removal and replacement now works as expected in all tested scenarios
(device removed, better driver installed, both with and without open device).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25512 a95241bf-73f2-0310-859d-f6bbb57e9c96
* added [un]publish_device() calls to the device manager.
* added a very basic devfs emulation to the playground to be able to test how
the manager reacts to opened devices.
* renamed *_device() functions to *_node() in the device manager API.
* made B_DEVICE_FIND_CHILD_FLAGS a generic flags field, and renamed it to
B_DEVICE_FLAGS.
* added support for keeping a driver loaded as long as its device is available.
* implemented get_next_child_node().
* added test for device removal, and implemented unregister_node() for this.
* fixed some bugs in the device node reference/initialization count maintenance.
* moved more code from register_node() to device_node::Register().
* initialize the device_node::fFlags member to the value of B_DEVICE_FLAGS, and
have additional private flags.
* renamed UninitUnusedChildren() to UninitUnusedDriver(), and fixed this
function by adding the new flag NODE_FLAG_REGISTER_INITIALIZED.
* Now remembers the support when a driver is registered - this will be used
later to be able to compare with a new driver without having to call
supports_device() again.
* Removed NODE_FLAG_REMOVE_ON_UNINIT again, as that was pretty stupid - there
is reference counting for a reason.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25498 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added a generic (for all devices) and specific (for a specific device) video
driver to be able to play with the replace mechanism (which is not yet done,
but works well for the one usage case tested).
* Added reference counting and initialize counting: now, each node owns a
reference of its parent, and each initialized node owns an initialization
reference of its parent.
* Added locking.
* Moved dump functionality into a member function.
* The same node can now only added once - ie. if a bus tries to register the
same device twice, it will fail.

any node (and not just your parent, which is guaranteed to be there).

interface information (in the PCI notion) to a node, and the possible paths
of a device driver are generated from that information by the device manager.
* Removed the "is bus" attribute - the device manager now decides wether or not
a device always loads its children (as opposed to on demand loading only),
even if the B_FIND_CHILD_ON_DEMAND flag is specified.
* device_node::Register() now correctly maintains the fRegistered member field.
* Replaced the driver_module() and driver_data() methods with a get_driver()
method that retrieves all information at once.
* Cleaned attribute names.
* Some other cleanup, adding const where it makes sense.
