This document provides the information on the system requirements for Intel® SoC Watch for oneAPI. Intel SoC Watch is available in Intel® oneAPI Base Toolkit as a part of Intel® VTune™ Profiler.
|Date||Version||Major Change Summary|
|Sep. 2021||2021.2||Enhanced WakeupAnalysis report with idle time per process.
Improved ia-throt-rsn support when Windows* OS secure modes are
|Jun. 2021||2021.1||Added System Name, Operating System name, kernel number, GUID to PMT description to the top of the summary and trace report. Update socwatch driver for Linux kernel 5.12 (SFI API was removed)|
|Mar. 2021||2020.5||Included in Intel VTune Profiler 2021.2. Changed hw-cpu-pstate to report frequencies per thread rather than per
core. Added term integrated to hw-igfx-cstate and hw-igfx-pstate report titles.
|Nov. 2020||2020.4||Initial Release|
Supported Target Operating Systems
- Linux Kernel version needs to be 2.6.32 or later.
- GNU C Library version must be GLIBC_2.17 or later.
- KERNEL_CONFIG_TRACEPOINTS must be enabled.
- Kernel should be compiled with "CONFIG_MODULES" enabled.
- Kernel config CONFIG_X86_SFI_CPUFREQ or CONFIG_X86_ACPI_CPUFREQ must be enabled (i.e. set
to 'y' or 'm').
- One of these pstate drivers must be utilized: sfi-cpufreq, acpi-cpufreq, or intel_pstate. To determine which driver is loaded, check the sysfs /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver file.
- If one of these pstate drivers is not loaded, the kernel needs to be reconfigured and recompiled.
- Kernel config CONFIG_TIMER_STATS must be enabled.
- Kernel config CONFIG_INTEL_IDLE must be enabled and the intel_idle kernel module has to support the core of the target platform.
- To determine if the intel_idle kernel module is loaded, check the sysfs /sys/devices/system/cpu/cpuidle/current_driver file. It must equal intel_idle. If it equals acpi_idle, only C0 and C1 will be usedby the core.
- Windows* 10, 11
- Using Microsoft’s Windows Subsystem for Linux 2 (WSL2) in Windows 10 and Windows 11, you can install the native Linux distribution of Intel oneAPI toolkits and libraries on Windows for CPU and GPU workflows.
