SCHED_HMP_LITTLE_PACKING

Not sure if you have the same issue on your device model, but I reverted my source back to my initial HMP task packing implementation and found out it was the cause of a bug as described in my commit:

https://github.com/UpInTheAir/SM-N915/commit/9f61827efb429b8e15cf57ebba884c1db5da6b35

I could easily test it by:

1. Enable data only
2. Volume mute and/or disable touch sounds
3. Keep rapidly tap the back soft key

System would start to "hang-up" and lag. Most of the time the device would appear to lag on touch/swipe input and quite considerable delay.

Still not sure if there is a conflict with any of my earlier commits, but is removed for now.

Cheers,

I might have "jumped the gun here" with this report. Sorry. Bug is back and just trying to sort through either ROM or kernel. Back to stock base. Cheers mate.

Did this cause the lag or not, didn't quite understand?

I'm aware of the issue as it happens when one unloads the Wifi module.

In the above case, my definition of "considerable delay" is ~1 sec.

I need to do more testing to try reproduce again. I have now reverted (unstaged) some other commits as well and cannot reproduce. I will later add just the HMP and see what happens and seen if lag is caused again. Was intermittent in testing and I couldn't make sense of the log at the time.

It doesn't appear in the log. The device just freezes outright.

Let me know if you single out the commit.
