This directory contains the changes needed to build a board's packages with thread sanitizer.
To build packages with thread sanitizer (tsan) for a board, create a profile in the overlays and point its parent to the appropriate architecture here. For example, to add an tsan profile for eve:
$ mkdir -p overlays/overlay-eve/profiles/tsan $ printf "../base\nchromiumos:tsan/amd64\n" > \ overlays/overlay-eve/profiles/tsan/parent
A private profile may be needed as well.
$ mkdir -p private-overlays/overlay-eve-private/profiles/tsan $ printf "../base\neve:tsan\n" > \ private-overlays/overlay-eve-private/profiles/tsan/parent
To build the eve board with tsan profile, do:
$ setup_board --board=eve --profile=tsan $ build_packages --board=eve
