Since yesterday the Linux-Libre Real-Time PPA is up:
https://launchpad.net/~linux-libre/+archive/rt-ppa

It contains currently the latest 3.6 libre-kernel with the latest rt patchset.
To add the PPA and to install the rt libre-kernel, type:

sudo apt-add-repository ppa:linux-libre/rt-ppa; sudo apt-get update; \
sudo apt-get install linux-libre-rt

Real-Time kernels have better latency than the usual kernels,
it is recommend for example for Music production on GNU/Linux.

Learn more: https://rt.wiki.kernel.org/index.php/Main_Page

Any feedback is welcome.

I actually chose your standard linux-libre kernel from your PPA and with you having a real-time one available, that is awesome for those who want to do audio and video editing on a GNU machine.

Btw I had this idea and tell me if it sounds crazy but what if you took your skills into modifying the standard Ubuntu kernels, created libre verisons of that version, and pushed it into the main Ubuntu repositories?

That way you could use your PPAs for testing before they go into the Ubuntu repos and makes it easier and one less thing for Trisquel and other Ubuntu based libre distros to worry about.

I am guessing the packages would be like this by following the Ubuntu naming scheme:

* linux-libre
* linux-libre-generic
* linux-image-libre
* linux-headers-libre
* linux-image-libre-generic
* linux-headers-libre-generic
* linux-image-3.2.0-35-libre-generic
* linux-libre-lowlatency
* linux-image-libre-lowlatency

These are just a few, but do you think this would be worth it to push into the main Ubuntu repos? Would it be too much work? Would you only do it if you got paid? You definately have the skills and experience to create something like this.

yo would be nice to have this in the trisquel (or even in the ubuntu) repo, just idk if this is welcome, especially on ubuntu.

linux-libre-lowlatency

not sure why we, or ubuntu, need a lowlatency kernel, if there is a real-time kernel. the lowlatency kernels have more soft settings... also i do not know the reason why ubuntu stopped to create rt kernels since lucid. (looks like you have to pay for a rt kernel now lol idk)

Would you only do it if you got paid?

no. all work that i did on free software (in at least 2 years) is free, without even a cent of donation or something. so if i can help with pushin libre software, i am all for it, and yes for free (just time is a factor).

I was very happy to learn that there's more work being done with -rt and linux-libre. Unfortunately I get the following error trying to install the PPA's kernel:

This kernel does not support a non-PAE CPU.
dpkg: error processing /var/cache/apt/archives/linux-image-3.6.11-gnu-3-generic_3.6.11-gnu-3.rt25.oneiric1_i386.deb (--unpack):
subprocess new pre-installation script returned error exit status 1
...
E: Sub-process /usr/bin/dpkg returned an error code (1)

Did you intend to produce a PAE-only kernel? Could you change the kernel configuration to support non-PAE CPUs? Or produce a kernel for non-PAE CPUs in addition to this one?

I will have a look into this, and will report later.

copy & paste this into your terminal:

sudo apt-add-repository ppa:linux-libre/rt-ppa; sudo apt-get update; sudo apt-get install linux-libre-rt; sudo apt-get dist-upgrade

Trisquel 6 = Precise, so you are set.

When you go to the https://launchpad.net/~linux-libre/+archive/rt-ppa page, it will give you instructions in how to add the PPA and then install.

Have activated the realtime repository and will be one of the first to try it when it comes out again (I'm on Saucy 64-bit).
