Another data point for debian 4.1 jessie preempt-rt on i686: I got a debian 8.1 (jessie) iso from: http://cdimage.debian.org/debian-cd/current-live/i386/iso-hybrid and installed on a lenovo SL410 laptop. Using zsync is very convenient.
I use xfce but several desktops isos are provided: cinnamon, gnome, lxde, kde, mate, xfce. Then I got the backport for the preempt rt 4.1 kernel using the /etc/apt/sources.list line: deb http://http.debian.net/debian jessie-backports main The package that i installed is: linux-image-4.1.0-0.bpo.1-rt-686-pae $ uname -a Linux u41 4.1.0-0.bpo.1-rt-686-pae #1 SMP PREEMPT RT Debian 4.1.3-1~bpo8+1 (2015-08-12) i686 GNU/Linux I was able to build linuxcnc (git 2.7) without problems. The machine (laptop) has latency spikes eventually, but an uninterrupted one hour run was about 40uS: http://www.panix.com/~dgarrett/stuff/histograms/debian-4.1-rt-sl410.png Latency spikes occur immediately when using the laptop FN-hotkeys for screen brightness or speaker control. Other jessie notes: 1) I couldn't find a jessie package for the glade-gtk2 editor so i tried the one on www.linuxcnc.org for wheezy: http://www.linuxcnc.org/dists/wheezy/base/binary-i386/glade-gtk2_3.8.0-0ubuntu6_i386.deb But this deb had a dependency for glade-gtk2 depends on libgladeui-1-11 (>= 3.7.2) so it didn't work on jessie. The libgladeui available on jessie is: ii libgladeui-2-6 3.18.3-1 i386 GTK+ User Interface Build core library The glade apps i looked at work ok (just not the glade-gtk2 editor) 2) I noticed scripts/latency-plot is hardcoded unnecessarily for wish8.5 but jessie has 8.6, I will make a git commit to fix. 3) the package for tclx seems to be named tclx8.4 (it worked) -- Dewey Garrett ------------------------------------------------------------------------------ _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
