1 This directory contains the prebuilt helper binaries necessary to grab traces 2 on the devices (e.g., memdump, ps_ext). The repository actually contains only 3 the SHA1 hashes (in prebuilt_name.sha1) of the latest version of the prebuilts. 4 The corresponding binaries are stored in Google Cloud Storage and synced on 5 demand at runtime (in this folder) by prebuilts_fetcher.py. 6 7 See http://www.chromium.org/developers/telemetry/upload_to_cloud_storage for 8 further instructions on how to update the files when a new version is required. 9
