Mega KD64 revival patch: KD64 - Fix some 64-bit issues and some x86 specificness. - Sub out some KdpTrap cases more properly. - Implement support for .crash and .reboot. Does not seem to work currently because of weird issues. - Implement KdpDprintf to send strings directly to the debugger from inside of KD64. Use it in KdEnterDebugger instead of DbgPrint so we won't try to enter the debugger recursively. - Implement KdUpdateDataBlock to set the KeUserCallbackDispatcher pointer in the debugger block after its address is retrieved from ntdll. - Don't assume breakpoints are 1 byte long in portable code -- use KD_BREAKPOINT_SIZE and define it per architecture. - KdpStub: KdEnableDebugger returns NTSTATUS, not TRUE/FALSE. Other - wdbgexts.h: Properly define CURRENT_KD_SECONDARY_VERSION for AMD64. - Make PsNtosImageBase pointer-sized as it should be. - Change the definition of KDSTATUS so it is guaranteed to be 32-bit. - Fix a critical bug in KiRestoreProcessorControlState: it didn't clear the busy flag in the TSS before reloading the task register, resulting in a GPF if we tried to reload the same register. - Add macros for getting and setting special purpose registers (the Program Counter and the "return register") in portable code instead of using #ifdef every time. Do likewise for setting IMAGE_FILE_MACHINE_XXX, using a new IMAGE_FILE_MACHINE_ARCHITECTURE macro. - Don't refer to the Program Counter as "Eip" in portable code. - Define DBG_STATUS_CONTROL_C for assembly code and use it in KeUpdateSystemTime. svn path=/trunk/; revision=43283

Default to xHalHaltSystem, a simple infinite loop, if we get called before HAL has initialized. Use this in KiBugCheckDebugBreak and the system shutdown handler instead of x86/AMD64/ARM intrinsics. - Don't try to halt the CPU if KeBugCheck has been called 3 times or more -- if this happens, something has gone very wrong, and we shouldn't try to do anything special. Just loop infinitely. - Fix KiBugCheckDebugBreak -- it shouldn't halt execution when called for the first chance as bugcheck callbacks have not been invoked at this point (nor has the BSOD been displayed). Use SEH to protect against a crash instead of checking KdDebuggerNotPresent as the debugger, if it is present, *could* disconnect while the trap is being handled. Also, don't halt execution if the debugger handled the breakpoint, just break again. - Don't call MmMapIoSpace from HalpReboot! The reboot might take place at elevated IRQL (as high as HIGH_LEVEL if called from KeBugCheck), and thus can't use any Mm support routines. Use a PTE from the reserved HAL region and map it ourselves instead as done in the BIOS call code. - Acquire the display ownership in HalReturnToFirmware in case the caller hasn't done so (as done in the KD reboot routine, for example). - Just include ntndk.h in hal.h instead of including 6 NDK headers (which turns into more than half of the NDK anyway since those headers include other NDK headers). - Crashing and rebooting from KD now works properly. svn path=/trunk/; revision=43380

Just loop infinitely. - Fix KiBugCheckDebugBreak -- it shouldn't halt execution when called for the first chance as bugcheck callbacks have not been invoked at this point (nor has the BSOD been displayed).

- DBGKD_WAIT_STATE_CHANGE64 is used in KD protocol 5, not number 6 that we use. Protocol 6 uses the DBGKD_ANY_WAIT_STATE_CHANGE structure which is sized according to the largest control-report structure (AMD64_DBGKD_CONTROL_REPORT currently), and is larger than DBGKD_WAIT_STATE_CHANGE64 on x86. This worked because our DBGKD_WAIT_STATE_CHANGE32/64 structures contained incorrect DBGKD_CONTROL_REPORT (used) and CONTEXT (unused) members that sized up the wait-state structure to pass WinDbg's length verification! It actually becomes larger than DBGKD_ANY_WAIT_STATE_CHANGE, but WinDbg only seems bail out only if the structure is too small. Remove the incorrect members from the protocol 5 structures and change to DBGKD_ANY_WAIT_STATE_CHANGE everywhere. - Correct the value of SIZE_OF_FX_REGISTERS -- it was 4 times too low which resulted in KeContextToTrapFrame not properly clearing out the XMM register area. Correct the define and move it out from ke.h to x86's ketypes.h and use it in the FXSAVE format structure. Also remove the IOPM definitions from ke.h as they have been in the NDK for a while. - KD uses STRINGs, not ANSI_STRINGs -- they are the same thing, but let's be consistent. - ExceptionRecord32To64 should be available for both 32 and 64 bit builds (and it shouldn't be a forceinline). Get rid of CopyExceptionRecord and determine if we need to convert or can just copy it directly instead. - Use _WIN64 instead of _M_AMD64 when determining if we need to set the DBGKD_VERS_FLAG_PTR64 flag. - Don't check Nt/DbgQueryDebugFilterState for zero or nonzero -- it actually returns TRUE, FALSE or STATUS_INVALID_PARAMETER_1! Check for != TRUE in preparation for proper implementation of NtSet/QueryDebugFilterState. - Fix Format parameter of DbgPrintReturnControlC -- it is const like the other DbgPrint* routines. - Be consistent with the types used in debug.c and don't set local variables to zero if we are going to return to caller -- this doesn't seem to be required anymore. - Fix DebugService and DebugService2: DebugService should take a ULONG followed by 4 pointers and DebugService2 doesn't return anything. - Use ZwCurrentProcess() instead of -1 or 0xFFFFFFFF (which is incorrect for 64-bit) for the ProcessId parameter of DbgLoad/UnloadImageSymbols to clarify what is being passed. Don't use ZwCurrentProcess() in KeBugCheckWithTf for the pointer parameter of DbgUnLoadImageSymbols either. Use MAXULONG_PTR casted to PVOID instead. - Use better named and sized variables in KdpTrap for setting the "return register" in the caller's CONTEXT. - Correct and clarify the comment documenting under what conditions we pass user mode exceptions to the kernel debugger. svn path=/trunk/; revision=43741
