Rewrite of Intel SGX SDK Switchless sample project to measure ecalls and ocalls. Measurments code Based on ISCA 2017 HotCalls paper, that can be found at (http://www.ofirweisse.com/previous_work.html) and intel SGX SDK Switchless sample.
make SGX_MODE=HW SGX_PRERELEASE=1; ./test_switchless
./run.sh to run the full benchmark.
The main benchmark function is at App/App.cpp.
Measurements of different type of calls are in measurements/<timestamp> directory:
- Empty_ecall_switchless.csv
- Empty_ocall_switchless.csv
- Empty_ecall.csv
- Empty_ocall.csv
The number of iterations is defined by REPEATS at App/App.cpp.
The round trip time of calls is measured in cycles, using RDTSCP insturction. The overhead of the RDTSCP insturction is roughly 30 cylces, which should be substructed from the numbers in the csv files. Different machines may have different overheads for RDTSCP.
