Log:
- Fix support for /CRASHDEBUG and /NODEBUG; we didn't respect those settings properly
and would initialize KD at boot even if they were set.
- Re-enable the breakpoint in vDbgPrintExWithPrefixInternal() as this works properly now.
Without this breakpoint some break-in requests got lost if the break-in occurred when
handling a debug print (happened a lot at boot).
- Implement Command String support for DbgCommandString() -- we now handle every debug
service call.
- Implement NtSetDebugFilterState() and NtQueryDebugFilterState() for KD, meaning we now
support debug filters properly.
- Implement KdRefreshDebuggerNotPresent(), KdChangeOption() and KdPowerTransition(). Stub
KdSystemDebugControl() to return error status instead of hanging the system.
- Stub the rest of the KD API to print a warning and return a failure packet instead of
hanging.
- Set and respect KdpContextSent when getting and setting the thread context -- WinDbg
doesn't seem to rely on this, but better safe than sorry.
- Support MP when getting and setting the thread context too -- if the context is
operation is for another processor than the current, just get it through the
KiProcessorBlock array.
- Initialize the MajorVersion in the KD version block more properly -- the high byte is
the major identifier (0 for NT). Add the required DBGKD_MAJOR_TYPES enumeration to
wdbgexts.h.
- Simplify setting and clearing the InDbgPrint flag in the TEB to minimize the impact on
kernel execution; use 2 dedicated routines instead of a generic one.
- KdpSymbol doesn't return anything, so don't return an ignore status from
KdpReportLoadSymbolsStateChange.
- Expose the KdpDefaultRetries and Kd_WIN2000_Mask variables to the registry and add them
to KDBG too (unused there).
- No reason to implement KdpSysGetVersion per architecture; move it back to the generic
code.
- Add some ARM offsets to the debugger data block that (N/A on other architectures).
- Fix the default size of the DbgPrint log buffer for free builds to save some space. It
should be 4 KB for a free build and 32 KB for a checked build.
- Move KeDisableInterrupts to cpu.c as it fits here more than in the IRQ support code in
irqobj.c.
- Use KeDisableInterrupts in KeFreezeExecution instead of checking the x86 EFLAG
directly.
