Good news everyone ;) UgDbg has kernel access, for the beginning it's limited to reading from it, that means no tracing will be possible of ring0 code. The readme in the current build will tell you how to enable it...

Features:

debugging of native x86 and x64 binaries

software and hardware breakpoints

Memory editor

Memory dumping

Memory search

Code highlighting

pdb support (display pdb information and if available the line information, also lookup of symbols including variables)

Conditional tracing (based on IP range)

Debugger is configurable and can autoexecute a list of commands on startup
