I found that some tasks have been running for a long enough time and
have become illegal, but they are still not releasing the CPU. This
will increase the scheduling delay of other processes. Therefore, I
tried checking the current process in wakeup_preempt and entity_tick,
and if it is illegal, reschedule that cfs queue.
When RUN_TO_PARITY is enabled, its behavior essentially remains
consistent with the original process. When NO_RUN_TO_PARITY is enabled,
some additional preemptions will be introduced, but not too many.
I have pasted some test results below.
I isolated four cores for testing and ran hackbench in the background,
and observed the test results of cyclictest.
hackbench -g 4 -l 100000000 &
cyclictest --mlockall -D 5m -q

I captured and compared the number of preempt occurrences in wakeup_preempt
to see if it introduced any additional overhead.
Similarly, hackbench is used to stress the utilization of four cores to
100%, and the method for capturing the number of PREEMPT occurrences is
referenced from [1].

From the above test results, there is a slight increase in the number of
preempt occurrences in wakeup_preempt. However, the results vary with each
test, and sometimes the difference is not that significant.

If I understand correctly, here it intends to check if the current se
has consumed its 1st slice after been picked at set_next_entity(), and if yes do a reschedule.
check_entity_need_preempt() is added at the end of entity_tick(), which could overwrite
the police to reschedule current: (entity_tick()->update_curr()->update_deadline()), only there
are more than 1 runnable tasks will the current be preempted, even if it has expired the 1st
requested slice.

As we changes the preemption policy for current in two places, the tick preemption and wakeup preemption,
do you have statistics that shows which one brings the most benefit?

The purpose of the modification is to increase preemption opportunities without breaking the
RUN_TO_PARITY rule. However, it clearly introduces some additional preemptions, or perhaps
there should be a check for the eligibility of the se. Also, to avoid overwriting the scheduling
strategy in entity_tick, would a modification like the following be more appropriate?

This modification no longer involves both wakeup and tick but is consolidated in 'update_curr', and it completes
the preemption decision along with 'update_deadline'. This approach seems more elegant and achieves the
same performance benefits as before.

I wonder if we can only take care of the NO_RUN_TO_PARITY case? Something like this,

Thoughts?

This does indeed look better. In that case, do I need to make the changes this way and send

If you mean the following changes, maybe we can continue the discussion here.
This is just my 2 cents, not sure what others think of it. Anyway, I can launch some tests.

Shouldn't this return false if "entity_eligible(cfs_rq, curr)" returns
true since curr is still vruntime eligible on cfs_rq?
Would it better to have check_curr_preempt() as follows:
if (sched_feat(RUN_TO_PARITY) || cfs_rq->nr_running <= 1)
return false;
return entity_eligible(cfs_rq, curr);
which returns false if curr is ineligible and scheduler can go ahead and
and call schedule to evaluate the next best step?
Please let me know if I'm missing something.

The above return should have been:
return !entity_eligible(cfs_rq, curr);
Which returns true once curr is not vruntime eligible on cfs_rq.
Sorry for the oversight.

Since the latest changes are completely different from version 2, so I have just released version 3.
Additionally, my testing environment is limited, and it indeed requires more testing to verify the
benefits it can provide. If possible, could you conduct tests using version 3?

Hello,
just like we reported for v1

we also noticed both improvments and regressions occur on different testcases
for this v2. just FYI.
kernel test robot noticed a -7.5% regression of netperf.Throughput_Mbps on:
