cuda component not properly reporting permission denied

[Vince Weaver]

The cuda component is returning EMISC when the error is actually permission denied (should be EPERM).

This might be a relatively new failure mode, but info on how to detect it can be found here: https://developer.nvidia.com/nvidia-development-tools-solutions-err-nvgpuctrperm-cupti

@Vince Weaver this is pretty old. do you have a reproducer?

If this is the CUPTI_ERROR_INSUFFICIENT_PRIVILEGES error I’m thinking of, you’ll need a sysadmin to re-enable profiling restrictions on a test system. From there, papi_component_avail should be enough to trigger the issue.
