8 months ago Hi @linguohua , thanks for your interest for HyperEnclave.
The code you have commented out:
preempt_disable();
header->online_cpus = num_online_cpus();
atomic_set(&call_done, 0);
on_each_cpu(enter_hypervisor, header, 0);
while (atomic_read(&call_done) != num_online_cpus())
cpu_relax();
preempt_enable();is the key operations to start HyperEnclave on the platform. So it is natural that you get
Initialize CMRM failin the log shown by dmesg.
In the case you provide, we may encounter some failures when starting HyperEnclave, but there is no dmesg log at early HyperEnclave initialization......(We are working in the progress to support such feature now). Currently we retrieve these information (for debug) from the output of Serial Port. It seems that the platform is a server, so could you please show the output of the Serial Port when you start HyperEnclave? (We usually get the output of Serial Port by typing the following command):
ipmitool -I lanplus -H [IP address] -U admin -P admin sol activate

Hi, I try HyperEnclave in Ubuntu20, when type 'bash start_hyperenclave.sh’, it always hang on, and freeze the whole system, I need to manual reboot the machine.
when comment out the following line in file: https://github.com/HyperEnclave/hyperenclave-driver/blob/0af18c3ea3a3935fd9bd5d08b901ff6a288b161d/driver/main.c#L456C2-L456C2
compile HyperEnclaveDriver and run again, it now does not hang on, but dmesg show error log: Initialize CMRM fail
