[NTOS:MM] Stop using PD_COUNT, PDE_COUNT and PTE_COUNT (#2294) Directly use PPE_PER_PAGE, PDE_PER_PAGE, PTE_PER_PAGE constants from hardware-specific MM headers instead 2020-02-05 22:48:26 +00:00			`PFN_NUMBER MmSystemPageDirectory[PPE_PER_PAGE];`
[NTOS]: Fix incorrect assumptions that a PDE == PTE which have crept up throughout new ARM3 code. [NTOS]: Fix a couple more unportable directly "Hard" PTE field accesses, instead of using portable MI macros. [NTOS]: Cleanup some of the pool code that had really messed up PDE vs PTE. [NTOS]: Define the number of page directoty levels for ARM. [NTOS]: Comment out some ARM3 code that won't be needed now that most of the x86 code is in C.

- Add 'simple' implementation of MmDbgCopyMemory to read/write virtual memory in a somewhat safe way (still no support for physical memory). Properly implement KdpCopyMemoryChunks as a wrapper around MmDbgCopyMemory and make most of the remaining unsafe copies use it instead of RtlCopyMemory. This fixes most of the remaining crashes during KD debugging as WinDbg/KD relies on the kernel support to handle bad addresses. - Stub out the remaining missing global variables for the debugger data block -- fixes some cases of WinDbg failures and gives it a chance to handle errors instead of failing on a NULL read. Several of these variables are for functionality we don't yet implement, so I tried to put them where they are "least wrong". Everything besides the MmLoadedUserImageList variable is left unitialized -- KD should mostly be able to handle this properly. - Define correctly sized KDDEBUGGER_DATA64 for our kernel (needs to be done in a better way). svn path=/trunk/; revision=43863 2009-10-31 01:02:35 +00:00			`PVOID MmSystemCacheStart;`

[REACTOS] Introduce four new debugging macros, ERROR_DBGBREAK, ERROR_FATAL, UNIMPLEMENTED_DBGBREAK, UNIMPLEMENTED_FATAL (and two helpers, __NOTICE and __ERROR_DBGBREAK). They are designed to display on the debug-log a printf-like user-defined message and to break into the debugger. - The _DBGBREAK macros break only into the debugger and allow to continue (they don't hang). - The _FATAL macros break into the debugger and then halt the execution. (Based on an idea of Aleksey Bragin, see the ros-dev mailing list about the while(true) --> assert(false); changes). [NTOSKRNL] Use these macros instead of ASSERT(FALSE); introduced in revisions r58110, r58111 and r58112 to replace while(TRUE); halts.
