- Implement Bus and I/O space read and write support.
- Implement support for AUTOENABLE, DISABLE and NOUMEX subparameters to /debug. Add the missing string scan and set and respect the related globals properly. Add support for disabling the debugger and suspending breakpoints.
- Add and implement KdIsThisAKdTrap to determine if the kernel debugger can't ignore a particular trap -- returns true for software breakpoints and debug service calls (DbgPrint for example). Called from KiDispatchException to determine whether to override NOUMEX (otherwise, DbgPrint and friends will kill user mode applications). Stub this for KDBG as it implements its own scheme for ignoring user mode.
- KiDispatchException: Clean up some goto and support NOUMEX. Also don't check if KiDebugRoutine is NULL -- it will never be.
- KdEnableDebuggerWithLock should initialize the debugger even if KdDisableCount is 0 (but only if called internally) as this means that the debugger was never initialized in the first place. Required for AUTOENABLE and for enabling the debugger during a bugcheck. Add the globals to kdbg too but don't set or respect them there as kdbg does not support it.
- Enable KdEnableDebugger and implement KdDisableDebugger for KD as KdDisableDebuggerWithLock is now implemented.
- Only build kdmemsup.c if KDBG is defined.

- Implement FatiOpenExistingFcb.
- Make FatGetFcbUnicodeName supporting DCBs.
- Implement FF_OpenW wrapper around FullFAT to support opening files/dirs using a unicode name.
svn path=/trunk/; revision=43528
- Add a function to read the dirent and return status of that object - does it exist, is it a file or a directory.
- Branch according to this in FatiCreate and try to open either an existing file or an existing directory. Directory open is stubbed.

- Paged pool PTEs are demand zero PTEs while the memory hasn't been accessed -- this is the only type of fault supported.
- Because paged pool PDEs are also demand-paged, added code to handle demand paging of PDEs as well.
- Also, because paged pool is non-resident, but can be accessed from any process, we need a mechanism to sync up the kernel's page directory with the per-process one, on demand. This is done at startup, but other processes may have paged in paged pool that another process knows nothing about when he faults.
- Similar to the hack ReactOS Mm uses, but done properly.
- This is what that shadow system page directory is finally being used for.
- Assert if we get a user-mode fault, a transition fault, or a soft fault, since these shouldn't happen.
- Disable APCs while dispatching faults, and pseudo-use the working set lock.
- Assert if we get write errors on read-only pages, since we don't use those in ARM3 yet.
- Assert if we have a paged out PTE, this shouldn't happen yet.
- Enable test to see if we can touch a paged pool allocation.
svn path=/trunk/; revision=43507
- Allocation does not support paged pool expansion yet, so we're limited to the initial 4MB that are initialized on startup.
- This only tests the raw page allocation routines so touching memory will fail as we don't handle paged pool faults yet.
- Nothing excercises this code path other than some simple tests while booting.
svn path=/trunk/; revision=43503
- Fix reading the incorrect pool type when freeing pool. The PoolType in the entry is offset by 1, so it can be either 1 for NonPaged or 2 for paged. This used to give us index 0 for nonpaged (correct), and index -1 for paged (oops!). Mask by 3 instead, so we get 0 and 1.

- Check for ARM3-owned memory areas during a page fault, and crash the system as this shouldn't happen yet.
- Use portable PTE macro instead of setting the owner bit directly, fixing an ARM port build issue.
svn path=/trunk/; revision=43488
- Remove overflow failure case, this isn't checked for string validation
- Adapt page check to let the full string be checked in case of overflow
See issue #4861 for more details.
svn path=/trunk/; revision=43487
- Add a new memory area type: MEMORY_AREA_OWNED_BY_ARM3. This will allow us to instruct the ReactOS Memory MAnager to "Back. The Fuck. Off." during page faults and such, so we can handle page faults inside ARM3-owned PTEs ourselves.
- Right now, all ARM3 PTEs and data is nonpaged, so no page faults should happen, but this may change in the future.
- Also will allow us to manage our own PDEs so we can do on-demand inpage instead of syncing with the ReactOS Mm hack cache.
- Create all memory areas in one shot in MmCreateSystemMemoryAreas (get rid of MiInitPageDirectoryMap and MiInitPagedPool memory area creation).
- Mark all of ours as owned by ARM3.
- Make them all static.
- The only non-ARM3 one right now is paged pool, we own all the other static areas.
- Move this code into mm, instead of mm/ARM3, since memory areas are not an ARM3 concept.
- Also create memory areas for session space, session view, and other ARM3 memory ranges, so nobody touches those ranges.
- Dump the kernel address space after all this is done, in a MmDbg function in mm.
- This cleans up ARM3 of some ROS-specific code, and also collapses Phase 1 and 2 into a single phase.

- Initialize PreviousStackBase/Limit to NULL in BasepCreateStack. Previously this bug was hidden because those values were ignored by the kernel.
svn path=/trunk/; revision=43485
- Initialize the paged pool guarded mutex.
- Add helper routines ExLock/UnlockPool to either acquire the NPP QSL or the PP GM depending on the pool descriptor, instead of hardcoding the NPP QSL.
- Implement InitializePool for the PagedPool case.
- Now call InitializePool for PagedPool as well.
svn path=/trunk/; revision=43482
- Add ARM3/mmsup.c for miscellaneous function helper functions.
- Implemented:
- Move MmIsRecursiveIoFault, MmIsThisanNtAsSystem and MmQuerySystemSize. These belong here.
- Unimplemented:
- Move MmSetBankedSection and fix the prototype. This should probably go somewhere else later.
- Move MmAdjustWorkingSetSize and fix the prototype. This should probably go in procsup.c later.
- Move MmMapUserAddressesToPage. This should also probably go in procsup.c later.
- Move MmSetAddressrangeModified and MmIsNonPagedsystemAddressValid. These should probably go somewhere else later.
