I got # RUN enclave.augment_via_eaccept_long ... # main.c:1241:augment_via_eaccept_long:test enclave: total_size = 8192, seg->size = 8192 # main.c:1241:augment_via_eaccept_long:test enclave: total_size = 12288, seg->size = 4096 # main.c:1241:augment_via_eaccept_long:test enclave: total_size = 36864, seg->size = 24576 # main.c:1241:augment_via_eaccept_long:test enclave: total_size = 40960, seg->size = 4096 # main.c:1259:augment_via_eaccept_long:mmaping pages at end of enclave... # main.c:1273:augment_via_eaccept_long:Entering enclave to run EACCEPT for each page of 8589934592 bytes may take a while ... # OK enclave.augment_via_eaccept_long The CPU used for testing was according to /proc/cpuinfo: model name : Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz I have couple of queries: 1. Is it possible to get dmesg output? 2. Do I have to repeat the test multiple times, or does it occur unconditionaly? BR, Jarkko
