sgx-hotspots Command Line Analysis
sgx-hotspots
Command Line Analysis This analysis is deprecated in GUI and available from command line only.
SGX Hotspots analysis type is targeted for systems with Intel Software Guard Extensions (Intel SGX) feature enabled. It uses the INST_RETIRED.PREC_DIST hardware event that emulates precise clockticks and helps identify performance-critical program units inside security enclaves. Using the precise event is mandatory for the analysis on the systems with the Intel SGX enabled because regular non-precise events do not provide a correct instruction pointer and therefore cannot be attributed to correct modules.
