- First, switch to using system PTEs as it should've been from the beginning. Our original implementation was broken and prone to race conditions, which Dmitry graciously fixed.
- We can now remove the MiZeroPageInternal hack that was used as a way to avoid deadlock/contention in the zero paths.
- Zeroing PTEs is done at DPC level in ReactOS, to avoid ReactOS-specific race issues. In Windows NT, this operation is always done at passive.
- Zeroing PTEs are similar to hyperspace PTEs, but they can be mapped in chunks for optimization.
- ReactOS does not currently make use of this functionality, so zeroing is pretty slow, especially on bootup if you have lots of memory (all RAM is zeroed).
- The existing ReactOS "compatibility layer" for hyperspace was augmented to seamlessly use the new zeroing PTE API.
- You must now unmap zeroing PTEs -- MiZeroPage was modified to do this.
- System PTE binning, NBQUEUES and SLISTS would optimize this further. TBD.
- Once again, tested on the trinity of supported emulators.

- Fix boot.
- The lack of colorful poetry is brought to you by cogent human beings on the West Coast whom you should be thankful haven't gone to bed yet.

- Implement System PTE allocator (MiReserveAlignedSystemPtes and MiReserveSystemPtes). Very simple yet functional, no optimizes for now.
- Allocate 32 zeoring PTEs from the System PTE pool.
- Not used yet, only the allocation is made to test the current framework.
- Tested on VirtualBox, QEMU and VMWare with RAM sizes from 128MB to 1536MB with no problems.
svn path=/trunk/; revision=41575
- DO NOT MAP HYPERSPACE PTEs as GLOBAL! They are now mapped as local, which might fix some really strange bugs that could've occured in the past.
- Use MiPteToAddress instead of manually doing the bitmagic when mapping a page into hyperspace.

- Secondly, initialize hyperspace in ARM³ now, at the correct place:
- Also, create the hyperspace PDE here, and not in FreeLDR, which was incorrect in the first place.
- This might help booting Windows/WinLDR.
- Install-tested w/ networking, with no issues found, on:
- Virtual Box 2.4
- VMWare 6.5
- QEMU 0.9.0
- PEBKAC?
svn path=/trunk/; revision=41573
- Add a new flag to MmGetContigousPages to specify if these pages should be zeroed or not. Allows the nonpaged pool pages not to get automatically zeroed when allocated (the NP pool allocator can do this by itself later). This allows initial nonpaged pool to be allocated before hyperspace is ready.
svn path=/trunk/; revision=41572
- ARM³ (Alternate ReactOS Memory Management Module) "stuff" is not ACORN Risc Machines (ARM) Port "stuff".
- We are lucky this user made this change before the rest of the code was checked in -- hyperspace, MDLs, nonpaged pool, kernel stacks, I/O mappings, noncached memory and contigous memory will soon all be built on ARM³ -- good thing this wasn't the case yet!
- Recommend this user gets banned for reverting code without approval within the 24hr grace period in ReactOS guidelines.
- If you have a bug to report, use Bugzilla, not your head as a sledgehammer.

- Check WrapperTable.KdpPrintRoutine.
- Allow to use GDB (/DEBUGPORT=GDB) and have debug output (/DEBUGPORT=COM1) at the same time.

- Use 7000 for systems with 19MB of RAM or less, 11000 for systems between 19 and 32MB of RAM, and 22000 for systems with more than that.
- Windows will go up to 50000 on server machines, but this is likely not needed now (22000 system PTEs is roughly 100 MB).
- This now affects the calculation of MmNonPagedSystemStart, which is now correct and reflects the nonpaged address space of the system.
- System PTEs are not yet initialized (but their page tables are mapped by the same code which maps nonpaged pool expansion VA page tables).
svn path=/trunk/; revision=41529
- Just supports expansion space for now, not system space.
- Very basic initialization of the accounting structures required.
- Sets up the first two system PTE clusters for the space (the first contains the linkage, the second contains the sizage).
- Called from MiInitializeArmPool.
