X-Git-Tag: v4.9-rc1~164^2~9 X-Git-Url: http://git.cascardo.info/?p=cascardo%2Flinux.git;a=commitdiff_plain;h=c0b172e5b6770048751b2c0a4fe44346c2080c5d Merge tag 'perf-core-for-mingo-20160901' of git://git./linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: - Support generating cross arch probes, i.e. if you specify a vmlinux file for different arch than the one in the host machine, $ perf probe --definition function_name args will generate the probe definition string needed to append to the target machine /sys/kernel/debug/tracing/kprobes_events file, using scripting (Masami Hiramatsu). - Make 'perf probe' skip the function prologue in uprobes if program compiled without optimization, using the same strategy as gdb and systemtap uses, fixing a bug where: $ perf probe -x ./test 'foo i' When 'foo(42)' was used on the "./test" executable would produce i=0 instead of the expected i=42 (Ravi Bangoria) - Demangle symbols for synthesized @plt entries too (Millian Wolff) Documentation changes: - Show default report configuration in 'perf config' example and docs (Millian Wolff) Infrastructure changes: - Make 'perf test vmlinux' tolerate the symbol aliasing pruning done when loading kallsyms and vmlinux (Arnaldo Carvalho de Melo) - Improve output of 'perf test vmlinux' test, to help identify on the verbose output which lines are warning and which are errors (Arnaldo Carvalho de Melo) - Prep work to stop having to pass symbol_filter_t to lots of functions, simplifying symtab loading routines (Arnaldo Carvalho de Melo) - Honor symbol_conf.allow_aliases when loading kallsyms as well, it was using it only when loading vmlinux files (Arnaldo Carvalho de Melo) - Fixup symbol->end before doing alias pruning when loading symbol tables (Arnaldo Carvalho de Melo) - Fix error handling of lzma kernel module decompression (Shawn Lin) Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Ingo Molnar --- c0b172e5b6770048751b2c0a4fe44346c2080c5d
