Basically used by annotate. Some (special) DSOs like kallsyms or JIT may not have the data though. * symtab type: determines where to read symbol tables. Set when symbols in the DSO are loaded. * debug info type: determines where to read debug info. Used by srcline, DWARF unwinding, data type profiling and so on. Often debug info is saved in a separate file. Some DSOs may have the same type for 3 and others can have all different. Previously it generally assumed binary type would be same as symtab type but now I think we should not and only set the binary type as it's used. Also it should make sure that symtab type is set properly after loading symbols in the DSO. Probably this patchset won't make any practical difference in runtime behaviors but I think it's good to track them accurately. v2 changes) * add dso__find_binary_type() for checking ".text" section * make perf annotate use the dso's binary type directly v1: https://lore.kernel.org/r/20261005063411.114244-1-namhyung@kernel.org Thanks, Namhyung Namhyung Kim (10): perf tools: Remove redundant dso data init perf tools: Try linked debug files for DSO debug info perf symbol: Update symtab type of vmlinux from build-id cache perf symbol: Set binary/symtab type for split kallsyms perf symbol: Set dso symtab type for libbfd perf tools: Factor out dso__find_binary_type() perf symbol: Set binary type for JIT map DSOs perf symbol: Do not set binary type from symtab type perf annotate: Simplify symbol__disassemble() with dso binary_type perf test: Fix dso data tests tools/perf/tests/dso-data.c | 6 ++ tools/perf/util/disasm.c | 116 +++++------------------------------- tools/perf/util/dso.c | 103 ++++++++++++++++++++++++++++---- tools/perf/util/dso.h | 13 ++++ tools/perf/util/symbol.c | 23 +++---- 5 files changed, 133 insertions(+), 128 deletions(-) -- 2.56.0.rc1.315.gc6ed9934b7-goog
