Linux Mint 17.3 / 64-bit - Uspace / Preempt-RT ?

Yes you can use the xconfig popup to disable unneeded drivers
You do need to make sure you enable the fully preemptable kernel in xconfig
you can speed things up quite a bit by using make -j4

Ok Thanks!
I"ll abort the 4.1.5 install, re-start with 4.4.7 and explore the settings in xconfig to gain a better understanding of what is actually going on during the kernel install.

PCW, what kind of latency do you get with the N3150 CPU and rt-preempt?

In response to my original post referring to the marginal graphics performance of N3150 CPU!

I found the reason for the marginal performance which had nothing to do with the CPU.
I had mistakenly installed LINUXCNC - 2.7.4-114-g92b991a by adding:
"deb buildbot.linuxcnc.org/ wheezy 2.7-rtpreempt"
to my apt-sources.list instead of
"deb linuxcnc.org/ wheezy base 2.7-uspace"
to install the official release "LINUXCNC - 2.7.4"

Being a new user I had actually done this on another install of a J1900 Cpu about 6 months ago and everything worked out well but I did not realize I was installing unofficial releases from the buildbot (until now when I encountered the problem).

LINUXCNC - 2.7.4-114-g92b991a was causing Gmoccapy to freeze which led me to blame the N3150 which now runs great with LINUXCNC - 2.7.4 installed onto wheezy 7.11 / 64bit with Preempt-RT. I'll continue to pursue the Mint route to see what improvements are to be had with the 4.4.7 kernel.

Perhaps It's a bit too easy sometimes for a new Linux user to type sudo apt-get install linuxcnc-uspace and not actually realize they are getting the latest version from what is defined in their apt-sources.list
Coming from windows it may help some folks to manually download the .deb package and install it with sudo dpkg -i to gain a better understanding of exactly which release they're installing.

Thanks,

On the Zotac CI323 I got pretty lousy latency (~120 usec) but for Ethernet and configs with the DPLL thats not terribly important since all the time critical sampling is de-jittered by the DPLL

Back to the Linux Mint 17.3 / 64-bit - Uspace / Preempt-RT setup.

After completing the following steps:
-Installed Mint / Mate 64-bit.
-Installed the Preempt-RT Kernel 4.4.7 per PCW's guide here: " forum.linuxcnc.org/forum/27-driver-board...7i77?start=180#62783 "
-And the following steps based on this guide: " www.wiki.eusurplus.com/index.php?title=LinuxCNC_Run_In_Place ":

sudo apt-get install git
git clone git://git.linuxcnc.org/git/linuxcnc.git linuxcnc-dev
cd linuxcnc-dev
git checkout 2.7
git pull
dpkg-checkbuilddeps

I've installed all unmet dependencies except for these:
Unmet build dependencies: linux-image-4.4.7-rt16 rtai-modules-4.4.7-rt16 | rtai-modules-4.4.7-rt16 linux-headers-4.4.7-rt16

Any insight on what I missed to have those listed as unmet dependencies or otherwise how to correct this?

Here is the output from uname -a
Linux LinuxCNC1 4.4.7-rt16 #1 SMP PREEMPT RT x86_64 x86_64 x86_64 GNU/Linux
