New Revision: 42148
URL: http://svn.reactos.org/svn/reactos?rev=42148&view=rev
Log:
- Initialize the value of MmBootImageSize in ARM3 now.
- Also fix its value such that it's PDE aligned -- this makes sure that we don't step on any of the boot loader's PDE mappings and can blow everything away later.
- Initialize the MmSystem/User/Probe Addresses in ARM3 as well (no functional change).
- Print out a lot more of the VA ranges in ARM3's Phase 2 initialization. Most of the VA space is now dumped out.
- Write out the code to initialize session space VA ranges
- Image space, view space, working set space and pool space values are all calculated properly.
- NT default sizes are used, without support for registry overrides (yet).
- Also system view space is initialized and sized.
- Code is heavily commented and explained for inquisitive minds.
- Define the paged pool start address, minimum/default size, and add some extra pool header asserts/definitions.
- Define MmPagedPoolInfo to keep track of all paged pool related information (start/end PTEs, VA ranges, allocation/free bitmaps, etc).
- Fixed a lot of comments and added some new ones to provide extra clarity.
- Implement MiBuildPagedPool. It has two jobs:
- Build and create the shadow system page directory, which double-maps the System process' PDE.
- More explenations are in the comments.
- Define the paged pool region and size, and initialize MmPagedPoolInfo accordingly.
- Create and setup the paged pool allocation and free bitmaps (again explained in the comments).
- There shouldn't be any real functional change yet due to this commit.
- We need to create memory areas for session space and system view space otherwise the VA regions could get used by ReactOS instead.
