If I set smt=off and try to configure cpupools with credit(1) as if all cores
are available, I get the following crash.
The crash happens when I try to use xl cpupool-add-cpu on the disabled HT
sibling cores.
Hyper-threading is enabled in the firmware, and only disabled with smt=off.
So

Hi Juergen,
Sorry for the late reply.
Here are the commands I execute, it is 'xl cpupool-cpu-add pcores 4-15' that
crash the system.
xl cpupool-cpu-remove Pool-0 4-31
xl cpupool-create name=\"ecores\" sched=\"credit\"
xl cpupool-cpu-add ecores 16-31
xl cpupool-create name=\"pcores\" sched=\"cr

You are right about sched-gran=core being the issue.
I don't know if this is relevant, but my CPU shouldn't be able to use
sched-gran=core it's asymmetric.
smt=on with sched-gran=core gives me a warning that it's falling back to
sched-gran=cpu, I tested smt=off with sched-gran=cpu and it works.
