performance optimization within enclave

[Matthias_H_Intel]

Is there any tool (SEP, VTune ...) which would allow to somehow analyze enclave SW (non release, e.g. debug build). If so, is there any documentation? 

[Kuppusamy_R_Intel · Accepted solution]

An enclave is an isolated environment. Performance analysis tools such as AQtime*, perf tools, VTune*, Valgrind* are not supported inside an enclave. The Intel® Software Guard Extensions Evaluation SDK provides a tool called sgx_emmt to measure the real usage of protected memory by the enclave at runtime.

Please refer the following link for more details "Intel® Software Guard Extensions Evaluation SDK"

Chapter 7 of the PRM details some of the performance / debugging that is available in the architecture:

Searching for SGX in the VTune release notes indicates which version of VTune has some support for SGX:

EDIT:
However, version 1.1 of the software does not include support for VTune.

SGX 1.6 is now available, with "Support for profiling SGX applications using Intel® VTune™. To profile SGX applications, use VTune™ 2016 Update 2 which contains an analysis type, SGX Hotspots"
