Negative frame time values when running `replayer.py profile trace`
During some statistics extraction from https://grafana.freedesktop.org/d/aH__CPd7z/mesa-driver-performance database, I found some negative values from the frame times for this command:
/piglit/bin/replayer.py profile trace --output /results --device-name gl-intel-kbl --download-url http://caching-proxy/cache/?uri=https://minio-packet.freedesktop.org/mesa-tracie-public/ --db-path /builds/mesa/mesa/replayer-db/ gputest/pixmark-volplosion-v2.trace"
Source: https://gitlab.freedesktop.org/mesa/mesa/-/jobs/26716659/artifacts/raw/results/results.json.bz2
- Extract results.json.bz2 file
- Open results.json
- Look at Line 2964.
This phenomenon sometimes happened in the past weeks. Here are more data extracted from the time series database. 2022-09-09_00_45_influxdb_data.csv
