Hi all, I am hacking xen source code with build-in debugging tools (xm debug-key). In /xen-xxx/xen/common/keyhandler.c, a bunch of handlers are registered for debugging. Does anyone know, how to enable those configurations in compiling, such as "PERF_COUNTERS", "NDEBUG" etc ? add "PERF_COUNTERS ?= y" in /Config.mk? I am a bit new to gcc makefile style.
Many thanks. Best Regards, Luwei
