New Revision: 58974
URL: http://svn.reactos.org/svn/reactos?rev=58974&view=rev
Log:
Merge my current work done on the kd++ branch:
- FreeLdr is able now to load personalized Kernel Debugger Transport DLLs by
reading at the kernel command line and interpreting the /DEBUGPORT=xxx entry
(--> loads KDxxx.DLL dll in \SystemRoot\System32\).
Therefore we can not only load the "default" kdcom.dll, but also 3rd-party
ones such as kdbazis.dll from VirtualKD (from revision 58902).
- The GCC-compiled-only version of kdcom, containing legacy COM code, was
removed and put directly along KDBG. It remains only a stub / template for
future kdcom-like dlls. The MSVC-version remains untouched.
- Make those functions ^ use directly the CPORTLIB library.
Added:
