The most critical use case for the new CPU pinning is realtime, as this implementation does not really pin CPUs. I would switch to it if it does not worsen...

It would be nice to remove the custom patches in this case. But I don't see how the QEMU vanilla pinning is used here? To run with the native CPU...

I would just cherry-pick the original commit and save the commit message. ``` git remote add ohmspectator [email protected]:OhmSpectator/eve.git git fetch ohmspectator git cherry-pick 32ec62b016016792d2c07512428f2e50559e7c34 ```

@roja-zededa, any progress on manual testing?

You can also run EVE in QEMU with a given amount of VCPUs =)

@roja-zededa, please address the rest of my comments here: https://github.com/lf-edge/eve/pull/4212#pullrequestreview-2404369311 1. I want to understand what are the the threads that run only on a given subset of CPUs and...
