May be I am not make myself understood. The uhook is not like kgdb, kprobe or some other debug tools. As I mentioned in previous mail that we can run the kernel ksymbal while kernel is running, not like the kgdb that need some hardware driver support (lots of problems occurred when I try kgdb),
uhook is more "soft", it just provide a way that can call kernel routine or ksymbals Asynchronously.
Easy but efficent. I have used it to develop device drivers, very nice, and not every platform or board support kgdb. > >> Is there some where else >> that can hold this tool, and let more people use the uhook? > > You have github, don't you?
