6.17. CUpti_ActivityEnvironment

struct CUpti_ActivityEnvironment

The activity record for CUPTI environmental data.

This activity record provides CUPTI environmental data, include power, clocks, and thermals. This information is sampled at various rates and returned in this activity record. The consumer of the record needs to check the environmentKind field to figure out what kind of environmental record this is.
