There are 3 improvements: - validate that kcore matches the perf.data modules - workaround objdump difficulties with kcore - add kcore to the build-id cache Changes in V6: perf tools: make a separate function to parse /proc/modules Dropped because it has been applied perf tools: workaround objdump difficulties with kcore Renamed some functions and reordered parameters perf buildid-cache: add ability to add kcore to the cache Renamed some functions and reordered parameters Changes in V5: perf tools: make a separate function to parse /proc/modules Use scnprintf not snprintf perf tools: validate kcore module addresses Fix check for mi->name not allocated perf buildid-cache: add ability to add kcore to the cache Use scnprintf not snprintf perf tools: add ability to find kcore in build-id cache Use scnprintf not snprintf Changes in V4: perf tools: fix path unpopulated in machine__create_modules() Dropped because it has been applied perf buildid-cache: add ability to add kcore to the cache Tweaked Documentation/perf-buildid-cache.txt perf tools: add ability to find kcore in build-id cache Changed to check read access to /proc/kcore before skipping the buildid cache Changes in V3: perf tools: workaround objdump difficulties with kcore change strncpy to strlcpy perf buildid-cache: add ability to add kcore to the cache change strncpy to strlcpy perf tools: add ability to find kcore in build-id cache change strncpy to strlcpy Changes in V2: perf tools: fix buildid cache handling of kallsyms with kcore Dropped because it has been applied perf tools: fix path unpopulated in machine__create_modules() Use 'modules' pointer Adrian Hunter (8): perf tools: validate kcore module addresses perf tools: workaround objdump difficulties with kcore perf tools: add map__find_other_map_symbol() perf tools: fix annotate_browser__callq() perf tools: find kcore symbols on other maps perf tools: add copyfile_mode() perf buildid-cache: add ability to add kcore to the cache perf tools: add ability to find kcore in build-id cache tools/perf/Documentation/perf-buildid-cache.txt | 13 + tools/perf/builtin-buildid-cache.c | 148 +++++- tools/perf/ui/browsers/annotate.c | 10 +- tools/perf/util/annotate.c | 36 +- tools/perf/util/map.c | 27 ++ tools/perf/util/map.h | 2 + tools/perf/util/symbol-elf.c | 579 ++++++++++++++++++++++++ tools/perf/util/symbol-minimal.c | 15 + tools/perf/util/symbol.c | 384 +++++++++++++--- tools/perf/util/symbol.h | 17 + tools/perf/util/util.c | 18 +- tools/perf/util/util.h | 1 + 12 files changed, 1165 insertions(+), 85 deletions(-) Regards Adrian
