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? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
