- Fixed new bug in palette drawing (replacing a + by a -)
- Added "Show grid" and "Show miniature" functions
- Therefore changed the menus -> please check translations

- Implemented new PostMessage and SendNotifyMessage, this is for bug 4646. I realize the need to update/sync dde code from wine. This relates to the new post and send functions and the use of MsgiKMToUMMessage. Trying to understand this mess.
- CreateDesktop is used to create the HWND_MESSAGE for the desktop. This is a work in progress. The ntuser prototype is updated too. Now pass the correct data from user to kernel space.
- Major update to event code and testing with user32 wine test msg. ATM, only two ntuser notifications are sent if the app has a event hook. Need to add more notifications at the correct points.
- Code arranging in hooks. Testing with user32 cross test works, need to add more ntuser hook calls at the correct points.
- Testing: More is required! User32 cross tests win and msg, win test hangs at flush_events. FF 1.5.x (Still has that funny minimize bug. Play with it and see. Missing one more check I think.) and AbiWord 2.4.1. Notepad lite is doing something very naughty inside it's hook call, with out the source, testing it will be imposable, so someone needs to find an open source program that does the same thing.

- I need to do more investigation on which values need to be restored but I know CurrentLookahead is one of them
- Add support for protocol-initiated miniport resets
svn path=/trunk/; revision=41718
* Use a documented ENG_EVENT structure (thus be compatible with Windows videoprt/win32k) instead of a stupid (PKEVENT) casting everywhere through EngEvent or VideoPort event functions;
* Implement additional checks for user mapped events in EngDeleteEvent and EngWaitForSingleObject;
* Implement EngReadStateEvent and EngClearEvent.
* Provide a better, readable code which matches kernelstyle coding guidelines;
* Remove (stub out) totally incorrect and buggy map user events support;
- Compile videoprt with ms-extensions flag enabled.

- Cleanup some externs that were never referenced in mminit.c.
- Remove MiShutdownMemoryManager since it was dead code.
- There is no need to define the MiKseg0Start/End variables and loop through the memory descriptors to find the last kernel image. We already have this information through LoaderPagesSpanned saved in MmBootImageSize.
- Removed these variables, code that depended on them, and MiGetLastKernelAddress, and switch to just using MmBootImageSize, which simplifies things a lot.
- Also simplify the way that the initial memory latout is setup. Now the PFN database will always start after MmBootImageSize + KSEG0_BASE, instead of relying on the fact FreeLDR, on certain machines, may have had leftover space in the 6MB allocation that it makes (And worse, assuming FreeLDR on all architectures will allocate 6MB).
- This standardizes the PFN database address and makes the code portable.
- Same for the nonpaged pool address.
- Should not call MmInitializeHandBuiltProcess for the idle process -- this will be called for the system process in PsCreateProcess.
- The only thing we need, as the comment says, is the kernel MADDRESS_SPACE, so just initialize the lock for it.
- Do not zero MmStats since the load-linker takes care of that for us since it's a global.

- Make the VA-range-printing debug prints match the same format as those in ReactOS Mm (MiDbgKernelLayout).
- Add the appropriate number of spaces so that the layout appears continuous, even though it's coming from two source files.
- This makes it easy to see the VA mappings at boot (but not all of them).

- These functions now use the MDL routines to allocate their physical memory, since the constraints and requirements are identical as for a non-cached MDL mapping.
- As for the virtual address space, it is guaranteed once again by System PTEs!
- If it's not getting old already, optimizations to the System PTE code will, yet again, yield improvements here as well.
- This is the last large kernel-facing memory allocator that needed updating to use System PTEs instead.
- Only the pool allocator remains (which, for nonpaged pool, also uses System PTEs, present in the nonpaged pool expansion VA).
- That effort will take significantly longer.
svn path=/trunk/; revision=41708
- MmCreateMdl, MmSizeOfMdl: No Change.
- MmBuildMdlForNonPagedPool: Do not use MmGetPfnForProcess, just normal PMMPTE manipulation.
- This seems to cause issues in certain scenarios, because in ReactOS, nonpaged pool, a resident and guaranteed resources, does not always have its PDEs mapped!
- By calling MmGetPfnForProcess, this wound up in the annals of ReactOS mm code, which lazy-remapped the PDE. We detected this issue specifically in the cache manager, and fixed it there. It should not appear anywhere else.
- MmAllocatePagesForMdl, MmAllocatePagesForMdlEx, MmFreePagesFromMdl:
- The *Ex function is now implemented.
- Allocating pages now uses MiAllocatePagesForMdl, which is based on the older MmAllocPagesSpecifyRange.
- The code is cleaner, better commented, and better handles partial MDLs.
- Cache flags are still ignored (so the Ex functionality isn't really there).
- MmMapLockedPages, MmMapLockedPagesSpecifyCache, MmUnmapLockedPages:
- These functions now use System PTEs for the mappings, instead of the hacked-up "MDL Mapping Space".
- This frees up 256MB of Kernel Virtual Address Space.
- Takes advantage of all System PTE functionality.
- Once again, optimizations in the System PTE code will be felt here.
- For user-space mappings however, the old code is still kept and used.
- MiMapLockedPagesInUserSpace and MiUnMapLockedPagesInUserSpace are now in virtual.c and provide this.
- MmProbeAndLockPages, MmUnlockPages:
- The pages are actually probed now, in SEH. This did not seem to happen before (did someone misread the function's name?)
- Probe for write is only done for write access to user pages (as documented).
- We do not probe/check for write access for kernel requests (force Operation to be IoReadAccess).
- Proper locking is used now: Address Space lock for user mappings, PFN lock for kernel mappings.
- Faulting in pages (to make them available before locking) is now done outside the address space/PFN lock.
- You don't want to be holding a spinlock/mutex while doing disk I/O!
- For write/modify access, if the PTE is not writable, fail the request since the PTE protection overrides.
- However, if the PTE is writable but also copy on write, then we'll fault the page in for write access, which is a legitimate operation for certain user-mode scenarios.
- The old version always provided the CopyOnWrite behavior, even for non-CopyOnWrite pages!
- Reference and lock every valid page that has a PFN entry (non-I/O Pages).
- The older code did not seem to lock pages that had to be faulted in (weren't already valid).
- Cleanup the cleanup code (no pun intended). Because we now mark the pages as locked early-on, and because of changes in MmUnlockPages, we can simply use MmUnlockPages in case of error, since it will be able to fully back-out and references/locks that we did.
- Previous code attempted to do this on its own, in a pretty inconsistent manner, which would leave page leaks (both in references and lock count).
- In MmUnlockPages, not as many changes, but we now:
- Still make sure that an I/O Mapping MDL doesn't have valid PFN database pages (non-I/O).
- An MDL can cover pages that are both I/O mapped and RAM mapped, so we have to unlock/dereference the latter instead of skipping them as the old code did.
- Use the PFN lock when checking pages and unlocking/dereferencing them.
- Overall, non-complete MDLs are now marked by having a -1 PFN, and the MDL code has been updated to early-break out of page-scanning loops and/or ignore such pages, which can happen in a sparse MDL.
- Implementation has been tested on VMWare and QEMU for a variety of tasks and was found to be reliable and stable.

- Remove syscolor pen support from win32k
- use gpsi->dwInstalledEventHooks instead of gpsi->SrvEventActivity
- remove reactos specific fields from SERVERINFO
svn path=/trunk/; revision=41679
- Fix PEVENT definition in video.h: it's not some mystic VIDEO_PORT_EVENT which is not defined anywhere, it's a documented structure, which has to be compatible with the structure used in win32k EngEvent* functions too.
