8347129: cpuset cgroups controller is required for no good reason

[antonvoznia]

Hi all,

Clean backport of JDK-8347129

Ran test locally on Fedora 43 arm, under test/hotspot/jtreg/containers/

Without the fix:

Test containers/docker/TestCPUAwareness.java fails because of JDK-8282684.
I also encountered this issue In JDK17.

Test containers/docker/TestPids.java fails in JDK21 and JDK17 as well where the fix persists already.

GHA Sanity Checks passed

Test containers/docker/TestCPUAwareness.java fails because of JDK-8282684.

I'm pretty sure the test fails because of JDK-8370492 on F43. JDK-8282684 is the reason why it doesn't show up for JDK 17+ (i.e. isn't tested there, but the issue exists).

[antonvoznia]

@jerboaa thank you for the note.

In my case the test failed TestCPUAwareness.java because of
"java.lang.RuntimeException: 'active_processor_count.*1' missing from stdout/stderr "

The test expects one active processor count, but the actual value is two:
[0.002s][trace][os,container] CgroupSubsystem::active_processor_count (cached): 2

Does the cpushare affect the active processor count number?

[jerboaa]

Does the cpushare affect the active processor count number?

For JDK 17 and below it does, yes. It's using -XX:+UseContainerCpuShares.

[antonvoznia]

@jerboaa I see, thanks
