perf dsos: Move the dsos struct and its methods to separate source files

2019-09-01T01:24:10Z

So that we can reduce the header dependency tree further, in the process noticed that lots of places were getting even things like build-id routines and 'struct perf_tool' definition indirectly, so fix all those too.

treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 251

2019-06-05T15:30:26Z

Based on 1 normalized pattern(s): released under the gpl v2 and only v2 not any later version extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 12 file(s).

pref tools: Add missing map.h includes

2019-02-06T13:00:38Z

Lots of places get the map.h file indirectly, and since we're going to remove it from machine.h, then those need to include it directly, do it now, before we remove that dep.

perf machine: Ditch find_kernel_function variants

2018-04-30T15:20:54Z

Since we do not have split symtabs anymore, no need to have explicit find_kernel_function variants, use the find_kernel_symbol ones.

perf tools: Remove unused 'prefix' from builtin functions

2017-03-27T14:58:09Z

We got it from the git sources but never used it for anything, with the place where this would be somehow used remaining: static int run_builtin(struct cmd_struct *p, int argc, const char **argv) { prefix = NULL; if (p->option & RUN_SETUP) prefix = NULL; /* setup_perf_directory(); */ Ditch it.

perf kallsyms: Introduce tool to look for extended symbol information on the running kernel

2017-01-11T19:48:01Z

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.
