- Handle various special cases in NtQueryVirtualMemory (e.g. querying illegal virtual addresses, shared memory area, etc). Example of an app doing this - OllyDbg.
svn path=/trunk/; revision=49277
Main features:
- Implement LDEVOBJ api. Responsible for loading dlls (display drivers, font drivers, keyboard layout, etc), replacing code in different locations.
- Implement PDEVOBJ api. A PDEVOBJ represents a physical device and is the core component for handling multiple display devices.
- Rewrite device locking. The new method was neccessary to allow dynamic mode switching.
- Implement support for enumerating display devices and settings.
- Implement dynamic mode switching.
- Implement a number of Eng mapping functions.
- Rewrite Eng level surface handling for cleaner code and better compatability.
- Rewrite parts of the DIB handling code.
- Rewrite DC creation and deletion. Deletion and cleanup is now completely callback based. Now we don't leak the DC objects when terminating a process, like we did before.
- Improve the XLATE and BRUSH code, removing several old hacks.
- Improve icon code.
Thanks to Jerome Gardou, Kamil Hornicek and everyone helping.

- One more leftover to add. Now we test for both Local and Global hooks in user32. This will force any message sent to win32k if there are any Global hookers so we loose in performance. We need to rethink our usage of these Global hookers in our code.

Simplify the RLE hack and avoid code duplication.
Bail out of UserEnumDisplaySettings early in case invalid ModeNum was requested.
Use default BPP value in UserChangeDisplaySettings if DM_BITSPERPEL is not set. Partially fixes "fullscreen issue" as described on the yarotows wiki page.
Remove some unused variables + misc cleanup.

Set proper flags and masks in BuildDIBPalette. Set PAL_BGR for 24/32 BPP in AllocPalette. Rename Mode to Flags to better reflect its usage. Fixes "red icons" and dibtest.

- Initialize Found to FALSE in NtQueryVirtualMemory. I wonder how GCC missed uninitialized var usage?
- Implement case when NtQueryVirtualMemory is called with non-existing virtual address.
See issue #3755 for more details.
svn path=/trunk/; revision=49261
- Fix a broken loop that resulted in us registering the resources of multiple COM ports as our KD port
- Fixes bug #5530
svn path=/trunk/; revision=49256
- Use new handle check functions in RCloseServiceHandle().
- RControlService: Check if a control request is acceptable for a user mode service before sending it to the service.

- Fix a critical bug in the conflict detection code
- Don't unconditionally skip conflict detection for shared resources, instead it should be done on a descriptor-by-descriptor basis (if both descriptors are shared)
- This check wasn't removed when I initially wrote this code and added the proper check below
svn path=/trunk/; revision=49252
- Check that we got a valid vector back from HAL when translating an interrupt resource
- Add some debugging messages for failure paths in device resource handling code
svn path=/trunk/; revision=49251
- Fix an exception when set condition * first always is used then moving the mouse. There seems to be an initialization issue (The Init Bug) and not setting a desktop.
svn path=/trunk/; revision=49250
- Partially implement IoAssignResources so that it creates a non-conflicting resource list from the requirements but it doesn't claim the resources for the device in the registry
- Partially implement IoReportResourceUsage so that it checks the resource list for conflicts but doesn't claim the resources in the registry
- Please test this revision with a variety of hardware and drivers because it activates several code paths in the PnP manager
- If this causes problems, look for "Denying an attempt to claim resources currently in use by another device!" in the debug log and report the bug to me
svn path=/trunk/; revision=49249
- Rewrite the resource map code to fix a regression, several failures cases, and a few memory leaks
- Remove an incorrect definition of IopDetectResourceConflict in pnpreport.c (no idea how this didn't trigger an onslaught of warnings)
svn path=/trunk/; revision=49248
- Remove a wrong ASSERT
- Improve EngLoadImageEx to correctly handle the path and optional dll extension.
- Get rid of EngLoadDriver
svn path=/branches/reactos-yarotows/; revision=49245
- Fix multiple bugs in round buffer implementation
- Should result in less audio glitches, especially when playing audio files with low sample rates. Please report any regressions!
svn path=/trunk/; revision=49244
- Rewrite the topology filter / pin / node property handling
- Store property sets of filter / pins / nodes in a common property set array
- Write a common dispatch function, which serves as a trampoline for filter / pin / node property requests
- Private property handlers of the drivers are now accessible
svn path=/trunk/; revision=49243
- Remove silence buffer hack
- Stub DRM Property Handler
- Before stopping the audio pin, fill the dma buffer with silence samples
- create a subdevice descriptor for instantiated pins too
svn path=/trunk/; revision=49242
- Fix check if the pin can be instantiated another time
- Remove hack to close old
- Add function FreePin to remove its old reference
- Fix memory leaks / reference leaks in WavePci pin implementation
- Fix memory / reference leaks in WavePci Close implementation
svn path=/trunk/; revision=49238
- Fix property set support handler for topology nodes
- Check if the driver supports a basic support handler. In that case return the basic support handler
svn path=/trunk/; revision=49237
- Remove the reference counter from the common handle type as a handle is never shared or duplicated.
- Remove the access right from the service handle as it is not used.
- Dereference service manager handles and service handles in two separate functions that SEH-protect the initial access to the handle and signature check. This will protect SCM from bogus handles.

To sum up, this commit finishes FSTUB API implementation in the ReactOS kernel. This means one important thing: now ReactOS kernel knows about a bit about EFI and about GPT. No need to say that it's the first step into EFI support. But a lot more work is needed. Especially since the kernel is the only real entity in ReactOS to handle GPT. All the rest of the OS doesn't know anything about GPT.
A small note about FstubVerifyPartitionTableEFI(). This function is supposed to check whether a disk formated with GPT is valid, and if it's not, to fix it. First step is implemented. Second step isn't yet supported.
A general note about all that stuff: on GPT, backup table isn't properly handled for the moment, as ReactOS is experiencing disk geometry issues. That means it's not having the proper disk sectors count and then, can't find the backup table (which is located on last disk sector).

Hackplemented support for IOCTL_DISK_GET_PARTITION_INFO_EX. It will work fine for MBR partitions but will fake returns for GPT partitions.

[NTOS]: Add support to MiDeletePte/MiDeleteVirtualAddresses to handle Section VADs.
[NTOS]: Add support to MiDeletePte to handle valid, prototype PTEs.
[NTOS]: Add MEM_TOP_DOWN support to ARM3 section code.
[NTOS]: Add support for unmapping currently mapped ARM3 section views at process termination.
[NTOS]: Use the new ARM3 section code for mapping the NLS section in the system (tests the system-view mapping code) and in each new process (tests the data-mapping code). Section is correctly unmapped at process termination time!

[NTOS]: Fix many MDL API bugs: correctly check for I/O pages, use LIST_HEAD instead of -1, track system-wide locked pages, use the process working set lock instead of the address space lock, add check for cross-ring MDL mappings, and make some small optimizations.
[NTOS]: Make some more fixes in MmAllocatePagesForMdl, MmFreeMdlPages to make the PFN entries more "correct".
[NTOS]: Had a little breakthrough: instead of complicating our lives and hiding certain ReactOS-Mm fields inside legitimate ARM3/MMPFN fields, differentiate between "legacy" (RosMm) and ARM3 pages. The legacy allocator (MmAllocPage/MmRequestPageMemoryConsumer) will use the non-paged pool to allocate a MMROSPFN add-on (8 bytes), in which the RMAP list head and SWAPENTRY are stored. When a legacy "free" is done, this data is deleted. Additionally, we can now tell apart between ARM3 and RosMm pages, so appropriate ASSERTs have been added to make sure the two never cross paths (which should safely let us use all the PFN fields now and implement working sets, etc...). I don't know why I didn't think of this sooner.
