vtune: Error: Cannot collect GPU hardware metrics due to a lack of permissions. Use root privileges (recommended) or re-configure your current permissions to make sure you are a member of the render group and /proc/sys/dev/i915/perf_stream_paranoid value is set to 0.
vtune: Error: To run this analysis, do one of the following:
* Set the Stack size option to the unlimited value (0 in command line).
* Provide access to the performance events system with the /proc/sys/kernel/perf_event_paranoid value set to 2 or lower.
You can also configure driverless collection using Perf tool capabilities.
vtune: Warning: Access to /proc/kallsyms file is limited. Consider changing /proc/sys/kernel/kptr_restrict to 0 to enable resolution of OS kernel and kernel module symbols.
vtune: Error: Unlimited stack size (0) not allowed in driverless mode.

Hi Ikei,

Thank you for reaching out to us.

To run Vtune, root privileges are required. Simply add the sudo command when executing Vtune, and it will run with the necessary privileges.

Hope this helps.
