Config
Graphene :- Commit: f9ed396dba0fc3bb988c9cd53375306300a66178 Linux :- 5.12.0 upstream kernel
Issues
PAL Failures
TC-1: test_200_event The test expect to return “TEST OK” but it returned “Error at line 71, pal_errno: -1, debug: DkProcessExit: Returning exit code 1”
TC-2: test_900_misc Expected Result Query System Time OK Delay Execution for 10000 Microseconds OK Delay Execution for 3 Seconds OK Generate Random Bits OK
Actual Result: (Missing Delay Execution for 3 Seconds OK) Query System Time OK Sleeped 10078 Microseconds Delay Execution for 10000 Microseconds OK Sleeped 2993086 Microseconds Generate Random Bits OK

Steps to reproduce
PAL Failures cd Pal/regression make SGX=1 regression
LibOS Failures cd LibOS/shim/test/regression sudo make SGX=1 regression Failure Trace Logs.zip
LTP Failures: cd LibOS/shim/test/ltp make -j8 SGX=1 all sgx-tokens make -j8 ltp-sgx.xml
So is this regression because of:
- moving to the new Linux kernel, or
- moving to a new Graphene commit?
There seems to be something wrong with timings in this new Linux 5.12 kernel. Looks like all new regressions are about timings that are very slightly off.
@anjalirx-intel I don't remember if we agreed on some way of solving this issue... Is anyone looking at it? I think someone volunteered to check this. I will assign priority P1 for now and mark it as a bug.
