2020
Version 2020.3.2 (Intel® System Studio 2020 Update 3)
- Bug fixes.
Version 2020.3 (Intel® System Studio 2020 Update 2)
- Enabled Graphics Slice Concurrency report when using -f hw-igfx-cstate.
- The --help command now lists option --no-post-processing which can be used to delay post-processing.
Version 2020.2 (Intel® System Studio 2020 Update 1)
- Added collection of tool usage analytics.
- Added new features pch-slps0, pch-slps0-dbg.
- Improved error messages and help output. Enhanced driver security.
Version 2020.1 (Intel® System Studio 2020)
- Added support for Intel platform code named Comet Lake.
2019
Version 2019.12 (Intel® System Studio 2019 Update 5)
- Added support for Intel platform code named Ice Lake.
- Modified reporting of hw-cpu-pstate.
- For Linux OS and Android OS targets, this release uses the 2.10 version of Intel® SoC Watch. Refer to corresponding release notes for these platforms available below.
Version 2.10 (Intel® System Studio 2019 Update 4)
- Enhanced -f hw-cpu-pstate feature reporting to include Core P-state/Frequency Histogram summary.
- For Linux/Chrome, added features to report bandwidth of FPGA reads and FPGA writes.
- This is the last release to provide 32-bit support for Linux OS and Android-OS.
- This is the last release to provide support for Windows* 8.1 OS.
Version 2.9 (Intel® System Studio 2019 Update 2 and Intel® System Studio 2019 Update 3)
- Improved organization of reports in _trace.csv report.
- Improved informational message.
- Modified -f hw-cpu-cstate reports.
Version 2.7 (Intel® System Studio 2019 Initial Release)
- Adds support for Intel platforms code named Whiskey Lake and Amber Lake.
- Adds option to delay start of a workload (program-delay).
- Adds new group names to make it easier to find and select features.
- The -f hw-cpu-pstate summary report includes a new core P-state average frequency table containing the core P-state approximate average and actual average frequency.
- Adds guard against sampling bandwidth data too frequently on certain platforms.
- Adds energy metric for the Package.
2018
Version 2.6.1 (Intel® System Studio 2018 Update 2)
Intel SoC Watch for Linux* / Android*
- Adds "--log <filename>" option for logging console output to a file.
- Separates HWP reporting into its own feature name to allow finer grain selection of which metrics to collect. Use hw-cpu-hwp to get this data now, rather than cpu-pstate.
- Features cpu-cstate and gfx-cstate are now group names. The individual feature names are now hw-cpu-cstate and hw-gfx-cstate to align these names across all operating systems.
- The -f hw-cpu-pstate feature is now collected by sampling so this metric can be supported on any system. Since this is now sampled data, there is some loss in precision of the CPU P-state residency and the report format changes.
Intel SoC Watch for Windows*
- Adds "--log <filename>" option for logging console output to a file.
- Removes OS-based metrics that have comparable hardware metrics from the sys group to reduce post-processing time. The os-cpu-cstate, os-cpu-pstate, and os-gfx-cstate features should be listed explicitly when needed.
- Separates HWP reporting into its own feature name to allow finer grain selection of which metrics to collect. Use hw-cpu-hwp to get this data now, rather than hw-cpu-pstate.
