perf kallsyms: Introduce tool to look for extended symbol information on the running kernel
Its similar to doing grep on a /proc/kallsyms, but it also shows extra information like the path to the kernel module and the unrelocated addresses in it, to help in diagnosing problems. It is also helps demonstrate the use of the symbols routines so that tool writers can use them more effectively. Using it: $ perf kallsyms e1000_xmit_frame netif_rx usb_stor_set_xfer_buf e1000_xmit_frame: [e1000e] /lib/modules/4.9.0+/kernel/drivers/net/ethernet/intel/e1000e/e1000e.ko 0xffffffffc046fc10-0xffffffffc0470bb0 (0x19c80-0x1ac20) netif_rx: [kernel] [kernel.kallsyms] 0xffffffff916f03a0-0xffffffff916f0410 (0xffffffff916f03a0-0xffffffff916f0410) usb_stor_set_xfer_buf: [usb_storage] /lib/modules/4.9.0+/kernel/drivers/usb/storage/usb-storage.ko 0xffffffffc057aea0-0xffffffffc057af19 (0xf10-0xf89) $ Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-79bk9pakujn4l4vq0f90klv3@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
