don't check any longer whether the given number is the address of a
condition variable in the global hash table; we just assume it is a
valid condition variable pointer.

MethodDeleter cases.

before?! Is about 4% faster than before. If anyone sees a way to make it faster
yet, please shoot! I can watch movies fullscreen on a 2 GHz Core 2 Duo in
VESA with bilinear scaling, but it would be nice to use less CPU... :-)

const BBitmap* bitmap, BRect bitmapRect, BRect viewRect, uint32 options).
Only option so far is B_FILTER_BITMAP_BILINEAR.
* BView::DrawBitmap[Async](const BBitmap* bitmap, BRect viewRect) was accessing
the bitmap pointer without checking it. Would therefore crash when passing
NULL, unlike the other methods.
* The BPicture code already reserved room for the BBitmap flags, but did not
store the actual flags and neiter use them for anything. Since the bitmap
data is stored anyways, the bitmap creation flags do not matter. So I reused
this for the new bitmap drawing options.
* Rewrote Bitmap.h and removed the B_BITMAP_SCALE_BILINEAR flag again.
* Tried to optimize Painter::_DrawBitmapBilinearCopy32() a little by giving
the compiler better hints. There seems to be a marginal, possibly imagined
speed increase < 0.05 ms. ;-)

that from the start. Please review for possible binary compatibility problems!

need to be interpolated because the x index is right on a source pixel. This
prevents the out of bounds access for the second to last row in the last
column. Also the rightmost pixels where incorrectly interpolated with the
leftmost pixels of the next row. And it actually helps speed too of course.
* Added a compile time option to allocate the filter weighting and index
caches on the heap instead of the cache. I am not sure if it is a problem
though, I recall Haiku threads have quite a lot of stack space. The needed
memory depends on the target size. For a screen with 1920x1200, the caches
would need 12.5 KB. Allocating them on the stack saves about 0.2 ms on my
test system.

to provide asynchrounous (or only synchronous, if asynchronous is not
supported) I/O request support. It will eventually replace
{read,write}_pages(). None of the FS implementations implement them
yet.
* Implemented some support functions for request-based I/O. File system
implementations can use do_fd_io() which passes an I/O request to the
layer responsible for a given FD, and do_iterative_fd_io(), which
translates a request for a file to subrequests for the underlying
device and passes them on. Both fall back to synchrounous processing
when the io() hook is not supported.
Furthermore added vfs_synchronous_io() which should be handy for the
devfs to perform io_requests synchronously for devices that don't
support the io() hook.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26655 a95241bf-73f2-0310-859d-f6bbb57e9c96
added an IORequest::Init() version with that parameter. This makes
splitting an iovec array into IOBuffers/IORequests easier.
* Added IORequest::CreateSubRequest(). It creates and adds an IORequest
that covers a part of the range of the parent request, but may use
another file offset. This will be used e.g. in the way that the parent
request describes an I/O operation for a file while its subrequests
describe the same operation translated to the underlying device.
* Added IORequest::DeleteSubRequests(), which does the obvious. It's
also invoked in the destructor.
* Added method for iterating through subrequests.
* Made IORequestChunk::{Set,Reset}Status() protected. For both
subclasses some locking is needed (though different locking), so we
rather make this more explicit.
* Added IORequest::SetStatusAndNotify(), which is SetStatus() +
NotifyFinished() with proper locking.
* Changed the I/O request finished and iteration callback signatures.
The finished callback has got an additional "status" argument, since
the request itself may already be inaccessible at the time the
callback is executed.
* Changed IORequest::NotifyFinished(). The policy is now that if the
iteration callback fails, the method will do the finished
notifications. This simplifies things in the iteration callbacks.
* Fixed bug in IORequest::_CopyPhysical(): It didn't take into account
that the physical buffer could not be page aligned.

B_OP_COPY which is about 2.4 times faster than the AGG version (but of
course less generic). The speed up is even better for smaller and even
scales.

an invalid page state was supplied. The comment was misleading too,
as the pages weren't reserved upfront.

* When drawing BBitmaps with scaling in the app_server, use a bilinear
filter when a bitmap has this flag set. (Hope nobody objects, otherwise
I can revert or improve this. Performance can certainly be improved, since
the AGG implementation is too generic. But that goes for the nearest
neighbor implementation as well.)
* Flags are uint32, fix app_server side code to declare them correctly. Use
appropriate link methods in BBitmap and ServerApp.
* Enable the BeOS compatibility mode for B_RGB32 (works just like B_RGBA32
in B_OP_ALPHA mode).

after calling CommitModifications(). Now the pointer is recreated from the

express what this variable is about.
* Changed tracking of sModifiedNoSwapPages. It really counts
non-swappable pages only, now (if swap support is enabled).

should cause allocations to be made in a way that they cannot fail.
Not implemented yet, though.

* Split IORequest::ChunkFinished() into OperationFinished() and
and SubrequestFinished(). Moved the notification part into a new
method NotifyFinished().
* Added new IOScheduler thread for notifying finished requests.
IOScheduler::_Finisher() hands over finished request to it, unless the
requests don't have callbacks. We need the separate thread, since the
callbacks can potentially reenter the scheduler and thus cause
deadlocks.

true it will get a new reference to the address space.
* Changed vm_soft_fault(): Now it gets the address space as a
parameter (for page faults getting it happens in vm_page_fault()).
This should fix lock_memory_etc() for other teams -- it used the
correct address space before, but the invoked vm_soft_fault() always
used the current team's address space.
