The gki directory has one subdirectory per Kleaf architecture. Within each such subdirectory:

symbols - contains symbol list files
- base - a short list of symbols that are essential for ABI safety
- $partner - a symbol list file for a specific partner
  - maintained by the partner
  - e.g. kmi_symbol_list = "//common:gki/aarch64/symbols/acme"
  - e.g. tools/bazel run //modules:acme_aarch64_abi_update_symbol_list
abi.stg - the tracked ABI
- maintained by Kleaf
- e.g. tools/bazel run //common:kernel_aarch64_abi_update
abi.stg.allowed_breaks - a list of allowed ABI differences
- for use by Gerrit ABI monitoring
afdo - AutoFDO profile for building kernel for the architecture
