The PE support in perf is fairly new and "perf archive" hasn't been updated to work with it. In getting this working I've come across a number of bugs in perf that these patches aim to fix. The patches are independent and can be committed in any order. Some of these are because build-ids are now variable width. Build-ids in PE files are always 16-byte GUIDs; much of the existing code still assumes a 20-byte SHA-1 build-id. I've tried to make the minimal amount of changes to allow 16-byte build-ids to work with a debugcache from a perf archive. I'm new to kernel development so I apologize if I'm doing this incorrectly. Thanks, Nick Nicholas Fraser (4): perf buildid-cache: Don't skip 16-byte build-ids perf report: Load PE files from debug cache only perf archive: Fix filtering of empty build-ids perf report: Fix return value when loading PE DSO tools/perf/perf-archive.sh | 3 +-- tools/perf/util/build-id.c | 5 +++-- tools/perf/util/build-id.h | 4 +++- tools/perf/util/symbol.c | 12 ++++-------- 4 files changed, 11 insertions(+), 13 deletions(-) -- 2.30.0
