Latency test

Yes, audit=0 should be specified as a kernel parameter too.. Debian enables so much stuff that I forget all the things that need to be disabled.. audit=0 effectively disables things like Apparmor and SELinux.

  All night glxgears with youtube. But only one testing thread.. otherwise we have two processes on core optimised to run only one...

Would you be interested in trying my Gentoo image + installer? I'm working on a custom built Linux system with the entire userspace + kernel tuned specifically for low-latency, no speed step, no power management, no sleep/hibernate/suspend, no power save etc.. Lots of things stripped out. Debian and other distros only lets you go so far, so I've taken the initiative to try and build the best possible image for LinuxCNC and lowest latency. All that governor/power/CPU stuff should not even exist on a real-time kernel.
 

Ok. I have visited some friends, got 120gb old ssd for testing.

Awesome! Just to make sure I have all your hardware together, can you post your `lspci -k` and `lsmod` ?

Thanks!

Will do it tomorrow. Today finished upgrading my controller. Or not.. it is newer ends. Removed small add on panel.. new lcd was smaller, so i got some place for start stop buttons and leds..

A very nice console

Commands result

Thank you for that! So pretty standard stuff, any idea what you're using the AT24 EEPROM driver for?

RAID/LVM will not be included, I see this in your list. I will add BTRFS (also in your list) and F2FS support probably later, right now it's XFS and EXT4 only.

Bios acces for uefi modifications ? Will try to find it.

Ok.
 

I was eager to get BTRFS and F2FS squared away...

Installer now supports BTRFS, EXT4, F2FS and XFS.
