Stefan Ginsberg 1d161cccdd - Implement support for reading and writing physical memory for KD. The implementation uses a reserved mapping page to map the target physical address to. On x86 this page is located at virtual address 0xFFBFF000, and the PTE for this page is the last PTE of the nonpaged pool's PDE. Other architectures may need to reserve the PTE elsewhere. ... - The physical memory support relies on several Mm variables and structures to be properly set up. Add a new flag, MiDbgReadyForPhysical, and set it when the debugger support can handle physical memory requests. - Protect this page with a Memory Area to make the old Mm keep its dirty hands off it. - Does not support I/O space or cache flags yet. - Add generic KeInvalidateTlbEntry to invalidate a single TLB entry for a given address instead of flushing the whole TLB. Used by the debugger physical memory support as invalidating the whole TLB for every map and unmap of its debug PTE would incur significant overhead for large copies. Replace direct usage of __invlpg() with this in x86 code too. - Fix incorrect cache flag check and set in KdpRead/WritePhysicalmemory for write combined requests. The debugger's Uncached flag was checked instead of the Write Combined flag, and the debuggers Write Combine number (0x3) was set instead of Mm's flag (0x20). - Fix implementation of MmIsAddressValid (at least for x86; other architectures will need more checks). Just check the Address' PDE and PTE valid bits instead of using Memory Areas. - Add missing ASSERTs to ensure the Memory Areas for paged pool, the PCR page, and the Shared User Data page are created. - Add missing Memory Area for the 2 pages HAL currently uses for its own mappings on x86 -- previously, those pages could have been allocated by other parts of the OS, which would have resulted in serious corruptions. svn path=/trunk/; revision=43960		2009-11-04 22:40:18 +00:00
