Re: cyclictest

Interesting results. Even at 540 us worst case latency the stock kernel does quite ok'ish for audio. Regarding those RT results with one core acting up: did you try to run the RT cyclictest with 3 cores? I'm wondering if sacrificing one core wouldn't actually help. It could be also a matter of RT pr...

Re: cyclictest

It's CPU1 (the green line) that's letting the side down. :) The other three CPUs have a really good maximum latency -- around 50 microseconds. That's 0.05 milliseconds. It's interesting that CPU1 is so much worse than the others. Makes you wonder if there's anything tied to CPU1. If there's somethi...

Re: cyclictest

I found also (empirically) that 4.19 RT is exceptionally good, but I have unfortunately not much time to join the benchmark fest. Looking at the results from the old threads on LM, it seems we are getting better: most of the results 2y ago were around 150us, now we're reliably getting below 100us - ...

Re: One month and counting without RT kernel on Arch Linux

Yeah, Nvidia + RT is not the easiest going combo for audio (although it seems to be working for some people). But it is not up to Arch to delay upgrades to support proprietary drivers - rather the opposite ;-) Anyway, if you want to pitch Linux-ZEN against the latest stock or RT, why not run a few b...

Re: One month and counting without RT kernel on Arch Linux

I think the Archlinux zen kernel is the way to go. Another plus is that it uses the newer I/O schedules like kyber/mq-deadline/bfq for better multi read/wrrite performance on HDD's. This kernel also has optimized the RCU timer threshold setting for more responsiveness. Attached is a zip I created t...

Re: One month and counting without RT kernel on Arch Linux

Gimmeapill do you not disable obviously irrelevant stuff in your kernel config? I used to be able to build a trimmed down one in about 10mins on my old core2duo. Yes, I used to, but this became over time a lot more pain than it is worth. I also used to build the spartan way with "make localmod...

Re: One month and counting without RT kernel on Arch Linux

...and in the meantime, look what just made it to the AUR: linux-rt 4.19.10 You can install a pre-built RT kernel by adding this unofficial user repository. I prefer to build stuff myself in a clean chroot rather than use third party repos whenever possible, but it is true that 4.19 RT did take a s...

Re: One month and counting without RT kernel on Arch Linux

@merlyn: thanks the precisions, I never looked too far into the stock Arch kernel. I should have made more clear that stock Arch <> vanilla, but anyway this is true for more or less any distro. ...and in the meantime, look what just made it to the AUR: linux-rt 4.19.10 https://aur.archlinux.org/pack...

It's been a while since the last update, is the project still going?

Re: Zrythm - A free GNU/Linux Digital Audio Workstation (DAW) focused on electronic music and high modularity

Sorry for misleading you guys, I didn't mean to dump Ardour/Bitwig just yet Yes it is a very fresh project. The website is two days old, the gitlab master repo is getting updated daily, and there was no official announcement. But for a 6 month old one man project, I think this is pretty impressive a...

Re: One month and counting without RT kernel on Arch Linux

But, What are the minimun settings for audio work with stock kernel? Maybe add user to audio group and config the /etc/security/limits.conf file? This thread assumes a system already tuned for low latency audio work. (distro specific, but https://github.com/raboof/realtimeconfigquickscan is your fr...

Re: One month and counting without RT kernel on Arch Linux

Ha! I just had to reboot on 4.18 RT to open an old Renoise project. It is not night and day by any mean, but I have slightly less xruns (possibly also because of jack1). So 4.18 RT still has a tiny edge over stock 4.19/4.20 I would say, but it's a very close call. This makes me wonder how 4.19 RT wi...

Zrythm - A free GNU/Linux Digital Audio Workstation (DAW) focused on electronic music and high modularity

Hi Folks, Just spotted a new DAW in the Arch User Repository (I didn't try it but from the screenshots it looks rather good). Description from the site: About Zrythm Zrythm is built using C and the GTK+3 toolkit and borrows ideas, concepts and code from other projects such as Ardour, Jalv, Bitwig an...
