- Time has come to get rid of a slightly modified implementation of WINE's heap, which is a hack based on Windows 95's heap implementation, itself a hack of DOS memory management. It supported 3 out of the 18 possible NT Heap Flags, did not support custom allocation/deallocation routines, and was about 50-80x slower with fragmentation rates up to 500x higher when compared to NT's LFH (WINE is lucky because the advanced NT Heap features are used in kernel-mode usually, not in user-mode, and they are crossing their fingers for this being the same). Several high-end SQL/Database applications would significantly benefit from custom heap features provided by NT. Not to say about removing crappy support for a custom Commit routine and crappy support for User-defined flags and the User-defined value.
- So, the glorious moment for a new heap manager, which is (to remind you) a totally new heap manager, resembling real NT heap manager, based on data structures similar to Windows 2003 and Vista+'s heap structures, supporting advanced heap flags (e.g. useful for debugging), having substantially lower fragmentation rates (and thus speed and reliability), having native support for user-defined flags and user-defined values, also native support for a custom commit routine, which is very important for trunk's win32 subsystem. It also reserves, commits, decommits and frees memory on the fly, unlike existing heap manager which prefers to reserve and commit as much as possible, and doesn't decommit when it's no longer necessary. Not to say about support for per process heaps, with a proper lock, and a further support for a special so-called debug heap allocator (to be implemented in heapdbg.c) which will be useful for finding heap corruptions.
Yeah, I'm not a fun person :D

In streamout(): fix a number of formatting bugs, round floats, fix issue with large unsigned values that were treated as signed, simplify some code.
svn path=/trunk/; revision=49516
New implementation of all printf functions. It's stream based (like MS one is) rather than buffer based (like our old is). Floating point is not 100% finished, but current implementation is good enough to boot. It can be enabled by a config switch.

- Enumerate MIDI devices and provide all necessary functions to deal with them
[WDMAUD_KERNEL]
- Implement support functions which call the provided functions of mmixer library
- Fix a bug in device interface request ioctl handler
- Midi devices should now be visible, capabilities be retrieved and opened / close
- Writing data is not yet supported

- Apply a hack to filter out pins, which are not part of filter node processing path
- The hack filters out all pins which have a physical connection. Ideally the code should check if the pin is part of a different rendering path and in that case remove the pin.
- Revert 49167

Initialise PPB to zero.
The change from NtAllocateVirtualMemory to RtlAllocateHeap causes the memory to
be not automatically initialised to zero anymore.
Not every field of the PPB (for which the memory is allocated) gets explicitly
initialised, meaning this results in them having bogus values.
One of the now uninitialised fields is DebugFlags, which results in
DbgBreakPoint being called in NtProcessStartup. Simply ensuring the memory is
zeroed makes it all better again.
svn path=/trunk/; revision=49180
[RTL]: Make the PPB live in the Heap instead of having its own virtual allocation, fixing the issue above. Stop rounding it to a PAGE_SIZE, and just use the space required.

- Add support for topologies where pins directly connect to other pins without nodes in between
- Check if the topology contains node. Fixes assert hit in VmWare Player(sound is not working)
- Thanks to Caemyr for testing
svn path=/trunk/; revision=49166
- Fix a typo which lead to incorrect flags being forced. Fixes last remaining major winetest failures (only 1 GlobalAlloc/Free implementation related one is left to be fixed).
svn path=/trunk/; revision=49156
Hackfixed build by stubbing RtlpValidateHeapHeaders(), RtlpValidateHeapEntry() and hackplementing RtlpValidateHeap().
To be properly fixed.
svn path=/trunk/; revision=49155
- Implement registering event routine which gets called when a topology node (volume / mute node) changes
- Implement fetching event changes
[MMIXER]
- Implement support routines which get called when a topology node changes its state
- Volume changes / mute on/off changes should now be broadcasted again to all listening applications
svn path=/trunk/; revision=49151
- Rewrite topology node enumeration algorithm
- Old algorithm didnt properly take in account sum/mux nodes, may assign nodes to multiple lines and was not able to detect circuits which may lead to infinite loops
- New algorithm properly partitions the nodes and also checks if nodes has already been assigned. As a plus, it is also faster
- Algorithm based on msdn http://msdn.microsoft.com/en-us/library/ff538873(v=VS.85).aspx
- Tested on VBox 3.28 (AC97)
- Please retest supported soundcards for regressions
svn path=/trunk/; revision=49150
- Add special debug heap function declarations and stubs.
- Add a useful inline for detecting whether a special or normal heap is going to be used.
svn path=/trunk/; revision=49149
- Add ability to dynamically allocate UCR descriptors when preallocated amount is exhausted.
- Fix a few bugs in RtlpFindAndCommitPages and in deactivated RtlpDecommitFreeBlock.
- Enable free blocks decommitting.
- New heap manager would now be ready to replace the old one.

Implemented IopFetchConfigurationInformation(), IopCreateArcNamesCd(), IopCreateArcNamesDisk(), IopVerifyDiskSignature()
Removed IopApplyRosCdromArcHack(), IopGetDiskInformation(), IopAssignArcNamesToCdrom()
Finally, rewritten IopCreateArcNames()
To make it short, this is the rewrite of ARC names handling in the kernel.
This brings our kernel to a higher state of existence. Indeed, it's leaving NT4 design for a proper NT5.2 design, with less hacks, less ROS specific stuff and such.
This code handles the mount manager we don't have yet.

- Fix RtlQuery/SetHeapInformation prototypes, move them to an appropriate place.
- Implement RtlQuery/SetHeapInformation.
- Implement in-place block growing.
- Amount of winetest heap failures is down to 6 (3 exceptions still happen).
svn path=/trunk/; revision=49111
- Move (and cleanup) private heap definitions and structure to a standalone header file heap.h. It's explicitly included in heap_rewrite.c and heapdbg.c to prevent conflicts with the existing heap manager in heap.c.
svn path=/trunk/; revision=49071
- Implement setting/getting heap user values and flags (very easy provided heap design is now proper). Amount of winetest failures is down to 12 (but 3 crashes in child processes).
svn path=/trunk/; revision=49069
- Set proper heap flags (tail and free checking) in case heap validation is enabled. Fixes another bunch of winetests.
svn path=/trunk/; revision=49057
- Roel Messiant: Remove old-style Peb->ProcessHeaps assignment from RTL, it's already done by MM.
- Roel Messiant: Fix a typo (missing else) between two if branches, which fixes commit routine support.
- Properly save requested size if 0 was given (1 should be allocated, but 0 saved as a requested amount). Fixes winetests.
- Remove unnecessary dprints.
svn path=/trunk/; revision=49048
- Fix allocated/free memory fillers to match those Windows uses (winetests)
- Add missing coalesce-on-free flag check in RtlCreateHeap
- Turn on tail check/pattern filling in RtlAllocateHeap.
- Add extra stuff storage support in RtlAllocateHeap and its helpers.
- Set win32 statuses where necessary.
- Return success in RtlValidateHeap to reduce spam when running winetest.
