[rli9]

The requirement is

• add more torture_type, refer to rcutorture.yaml

$ cat jobs/rcutorture.yaml
suite: rcutorture
testcase: rcutorture
category: functional

need_memory: 300MB
runtime: 300s

rcutorture:
  test:
    - default
    - cpuhotplug
  torture_type:
    - rcu
    - srcu
    - srcud
    - tasks

• add corresponding spec tests

Acceptance Test

• There's valid rt for each tortoure type
• Spec tests pass

Hi, I am from LKP_Team 1. Can you provide more information on what to be check in the spec test?

Can you provide more information on what to be check in the spec test?

This can refer to spec/stats/locktorture, which uses the test result as input for parser script, and check whether the parsed stats is correct or not.

So for newly added torture types, we can extract the corresponding output from the rt and add to spec. It's possible the output is similar, in that case, only add spec for 1-2 torture type is enough.

BTW: refer to https://docs.kernel.org/locking/locktorture.html for torture_type, currently lkp only covers spin lock.

Type of lock to torture. By default, only spinlocks will be tortured.
