| zequence | Just tried Debian linux, and compared to a custom -lowlatency. Identical results on this machine. | 13:37 |
|---|---|---|
| zequence | Gonna do some testing with Ubuntu -generic kernel, and compare with -lowlatency | 13:37 |
| zequence | cyclictest was showing extremely nice results for my -lowlatency, compared to the "generic" Debian kernel, however, in practice, I can use the same latency setting for jack on both and I seem to have the same amount of dropouts | 13:57 |
| holstein | zequence: that seems good.. seems like what i have been hoping would just trickle into the generic kernel | 17:17 |
| holstein | i *cant* wait til im through building this house, and can maybe have a minute or 2 to test some things again | 17:17 |
| zequence | holstein: I need more time to test, and research what the difference is. This is just one machine. | 17:19 |
| zequence | Need to get a grasp on the new scheduler in use (which I had totally missed) | 17:20 |
| zequence | http://en.wikipedia.org/wiki/SCHED_DEADLINE | 17:20 |
| holstein | yup.. and i have found that with internal hardware and usb, i seemed to get different results, compared to the firewire device | 17:20 |
| holstein | and that was 12.10? somewhere around that time... | 17:21 |
| zequence | No, I think it's since Utopic actually | 17:21 |
| zequence | Since kernel version 3.14 | 17:21 |
| zequence | Trusty has 3.13 | 17:21 |
| zequence | Utopic 3.16 | 17:22 |
| zequence | 3.16 is the one with firewire support in alsa too | 17:22 |
| holstein | i mean, for me.. i was getting "similar" performance with the lowlatency and generic last time i tested.. with internal hardware and USB's | 17:23 |
| holstein | im stoked about alsa firewire as well | 17:23 |
| zequence | Doing cyclictest on this machine gave me numbers for lowlatency that I've only seen on a realtime kernel | 17:23 |
| holstein | out of the box firewire audio support!... just in time for firewire to become obselete ;) | 17:23 |
| zequence | But, it's a little premature to say anything. Besides, jack was not performing any better | 17:24 |
| zequence | Yeah :D | 17:24 |
| zequence | cyclictest is a part of rt-tools, a set of tools used for measuring rt kernels | 17:24 |
| zequence | There has been some talk about this deadline scheduler. Trying to catch up on all of that | 17:25 |
