From b935a58dbff457c27fd63e1e1bb29db20b2ee6a8 Mon Sep 17 00:00:00 2001 From: Josh Boyer Date: Wed, 22 Jan 2014 10:01:48 -0500 Subject: perf tools: Fix traceevent plugin path definitions The plugindir_SQ definition contains $(prefix) which is not needed as the $(libdir) definition already contains prefix in it. This leads to the path including an extra prefix in it, e.g. /usr/usr/lib64. The -DPLUGIN_DIR defintion includes DESTDIR. This is incorrect, as it sets the plugin search path to include the value of DESTDIR. DESTDIR is a mechanism to install in a non-standard location such as a chroot or an RPM build root. In the RPM case, this leads to the search path being incorrect after the resulting RPM is installed (or in some cases an RPM build failure). Remove both of these unnecessary inclusions.

Then the address passed to map->map_ip isn't mapped at the first time. E.g. below code always fails to get a symbol at the first call; addr = /* Somewhere in the kernel text */ symbol_conf.try_vmlinux_path = true; symbol__init(); host_machine = machine__new_host(); sym = machine__find_kernel_function(host_machine, addr, NULL, NULL); /* Note that machine__find_kernel_function calls map_groups__find_symbol */ This ensures it by calling map__load before using it in map_groups__find_symbol().
