I finally had some time to update to 4.11-rt.

Note that I still have slightly higher kernel scheduling latency than with 4.9-rt. I get cyclictest max values on the order of 150us instead of the normal 80us. Hopefully this is not a problem for any of you..!

If I hear no complaints I'll update linux-rt-lts to 4.9-rt soon.

Hi,

I didn't update to 4.14.3-rt5 since building vbox modules failed for 4.14 from testing as well as for the local build of 4.14-rt1.

$ pacman -Q linux{,-rt{,-cornflower,-pussytoes}}|awk '{print $2}'
4.14-2
4.13.13_rt5-1
4.11.12_rt16-1
4.14_rt1-1

I booted

[rocketmouse@archlinux ~]$ uname -r
4.13.13-rt5-1-rt

Regards,
Ralf

PS: I neither upgraded to 4.14.3-1, the current version available by testing.

What about 4.14?

I can't use my Bluetooth mouse (logitech mx master) with 4.13.10_rt3. I'll try to find more details.

Hi smoge,

if you should have questions regarding 4.13.7_rt1-1 or one of the RT kernels currently installed on my machine, send a request to https://lists.archlinux.org/listinfo/aur-general.

$ pacman -Q linux{,-rt{,-pussytoes,-cornflower}}
linux 4.13.9-1
linux-rt 4.13.10_rt3-1
linux-rt-pussytoes 4.11.12_rt15-2
linux-rt-cornflower 4.11.12_rt16-1

Ralf_Mardorf, how 4.13 is working for you?

FWIW building the package for 4.13.7-rt1 failed with "install: cannot stat 'Documentation/Doc/Book/Makefile': No such..."
"A failure occurt in package_linux-rt-headers:(). ...", obviously line 207, 208, 209 and 304 of the PKGBUILD are obsolet. The Nvidia patch could be still applied and IIRC oldconfig only requires to push enter all the times, assuming you don't want some new RME and a few new ALSA things.

I build 4.11.12-rt16 and tried to build 4.13.7-rt1 in the morning, in a hurry, before I needed to go to work.

smoge commented on 2017-10-18 05:09

I will test again with rt16. I just uninstalled rt15, I did not have the time to investigate the problem.

What error messages do you get?
Please, lets continue at https://lists.archlinux.org/listinfo/aur-general .
Jack does run on my machine.

Btw. 4.11.12-rt16 and 4.13.7-rt1 were released.

smoge commented on 2017-10-17 19:20

I could not start jack with 4.11.12-rt15 and went back to rt14. Is it a known problem?
