Tool get_device_info is used to collect either machine-info, software-config or trace-result proto buffers that are ready for uploading to the trace-result database. We'll look at all three scenarios in details below. However, you should look to tool Harvest to collect machine-info and software-config data from connected devices and automatically upload the result to the trace-result DB.
This document makes reference to trace-result DB protobufs. The definitions for these protobufs are found at https://chromium.googlesource.com/chromiumos/config/+/HEAD/go/api/test/results
-> scp get_device_info <cros-device-IP>
-> get_device_info machine-info -owner user/gwink > machine-info.pb -> cat machine-info.pb { "name": { "value": "b9ecaf8a-3bfd-411e-8240-89354a796065" }, "createTime": "2020-10-27T23:57:20Z", "owner": "user/gwink", "hwid": "HELIOS-YVRQ C5B-A4E-C4V-42Q-A3L" }
Note: Tool Harvest automates all these steps for any connected DUT. It will also assign a more readable and consistent machine name than the UUID shown above. It is highly recommended to Harvest instead of running get_device_info directly.
Use the same steps as above, but in step 2, collect the software-info instead:
-> get_device_info software-info -skip-packages > software-config.pb -> cat software-config.pb { "id": { "value": "8caff65e-b70b-46ee-ab21-f52e16e58d88" }, "createTime": "2020-10-28T00:08:44Z", "kernelRelease": "4.19.152", "kernelVersion": "#3 SMP PREEMPT Wed Oct 21 18:14:32 MDT 2020", "chromeos": { "board": "hatch-borealis", "buildNumber": 13545, "buildType": "Test Build - gwink", "chromeMilestone": 88, "description": "13545.0.2020_10_21_2021 (Test Build - gwink) developer-build hatch-borealis", "keyset": "devkeys", "name": "Chromium OS", "patchNumber": "2020_10_21_2021", "track": "testimage-channel", "version": "13545.0.2020_10_21_2021" }, "os": { "buildId": "13545.0.2020_10_21_2021", "id": "chromeos", "name": "Chrome OS", "versionId": "88", "version": "88" }, "biosVersion": "Google_Helios.12672.117.0", "ecVersion": "0x44" }
Notes:
This last use of get_device_info runs on your workstation. It is designed to process trace-profiles generated by tool Harvest into protobufs ready to be uploaded to the trace-result DB.
First, you need to know that Harvest appends extra data the profile generated by ApiTrace. For instance, the output of a simple FPS ApiTrace run collected with Harvest looks as follows:
-> cat tvc_steam_728880-overcooked__2-20200528_090359.trace.20200928-174541.crostini Rendered 6408 frames in 272.566 secs, average of 23.5099 fps >>>>>> Extra Tracing Info <<<<<< CMD: DISPLAY=:0 WAFFLE_PLATFORM=sl LD_LIBRARY_PATH=/home/gwink/lib/x86_64-linux-gnu /home/gwink/apitrace/glretrace -b /home/gwink/traces/tvc_steam_728880-overcooked__2-20200528_090359.trace > /tmp/tmp.bft0MYHEIw name of display: :0 display: :0 screen: 0 direct rendering: Yes Extended renderer info (GLX_MESA_query_renderer): Vendor: Mesa/X.org (0x1af4) Device: virgl (0x1010) Version: 20.3.0 Accelerated: yes Video memory: 0MB Unified memory: no Preferred profile: core (0x1) Max core profile version: 4.3 Max compat profile version: 3.1 Max GLES1 profile version: 1.1 Max GLES[23] profile version: 3.2 OpenGL vendor string: Mesa/X.org OpenGL renderer string: virgl OpenGL core profile version string: 4.3 (Core Profile) Mesa 20.3.0-devel OpenGL core profile shading language version string: 4.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL version string: 3.1 Mesa 20.3.0-devel OpenGL shading language version string: 1.40 OpenGL context flags: (none) OpenGL ES profile version string: OpenGL ES 3.2 Mesa 20.3.0-devel OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 TRACE_ID: tvc_steam_728880-overcooked__2-20200528_090359 EXEC_ENV: crostini MACHINE_NAME: gwink-sona-C097462
To generate a trace-result protobufs for that profile you would run get_device_info as shown below. But pay attention to a couple of things:
get_device_info will pick up the machine name from the input file, if it is there. Otherwise, you must also specify it on the cmd line.-> get_device_info trace-result \ -software software_info_crostini_gwink-sona-C097462.json \ tvc_steam_728880-overcooked__2-20200528_090359.trace.20200928-174541.crostini.prof > overcooked_2_pb.json -> cat overcooked_2_pb.json { "value": [ { "id": { "value": "user/gwink-tvc_steam_728880-overcooked__2-20200528_090359-20200928-174541" }, "startTime": "2020-09-28T23:45:41Z", "endTime": "2020-09-28T23:50:13Z", "machine": { "value": "gwink-sona-C097462" }, "softwareConfig": { "value": "9146de0d-1378-4c83-968e-a9427ac5f91f" }, "executionEnvironment": "CROSTINI", "invocationSource": "user/gwink", "commandLine": "DISPLAY=:0 WAFFLE_PLATFORM=sl LD_LIBRARY_PATH=/home/gwink/lib/x86_64-linux-gnu /home/gwink/apitrace/glretrace -b /home/gwink/traces/tvc_steam_728880-overcooked__2-20200528_090359.trace \u003e /tmp/tmp.bft0MYHEIw", "benchmark": "apitrace", "trace": { "value": "tvc_steam_728880-overcooked__2-20200528_090359" }, "metrics": [ { "name": "frame_count", "value": 6408, "units": "frames" }, { "name": "duration", "value": 272.566, "units": "seconds" }, { "name": "frame_rate", "value": 23.5099, "units": "fps", "largerIsBetter": true } ], "primaryMetricName": "frame_rate", "labels": [ { "name": "CMD", "value": "DISPLAY=:0 WAFFLE_PLATFORM=sl LD_LIBRARY_PATH=/home/gwink/lib/x86_64-linux-gnu /home/gwink/apitrace/glretrace -b /home/gwink/traces/tvc_steam_728880-overcooked__2-20200528_090359.trace \u003e /tmp/tmp.bft0MYHEIw", "grouping": "apitrace" }, { "name": "vendor", "value": "Mesa/X.org", "grouping": "glxinfo" }, { "name": "renderer", "value": "virgl", "grouping": "glxinfo" }, { "name": "core profile version", "value": "4.3 (Core Profile) Mesa 20.3.0-devel", "grouping": "glxinfo" }, { "name": "core profile shading language version", "value": "4.30", "grouping": "glxinfo" }, { "name": "version", "value": "3.1 Mesa 20.3.0-devel", "grouping": "glxinfo" }, { "name": "shading language version", "value": "1.40", "grouping": "glxinfo" }, { "name": "ES profile version", "value": "OpenGL ES 3.2 Mesa 20.3.0-devel", "grouping": "glxinfo" }, { "name": "ES profile shading language version", "value": "OpenGL ES GLSL ES 3.20", "grouping": "glxinfo" } ] } ] }
When it comes time to upload trace-result protobufs to the DB, look for python script bq_insert_pb.py in https://chromium.googlesource.com/chromiumos/platform/graphics/+/HEAD/src/results_database/
