hi,<br>
<br>
I am trying to bring up Litmus-rt for testing and analysing<br>
joint-scheduling algorithm, I am trying to build it on ubuntu 12.04 KVM.<br>
<br>
I was trying to create a basic userspace which i can use to test my<br>
scheduling , but i am not finding a clear solution for this, Should i write<br>
my own init and configure my whole user-space or is there any short cut for<br>
this?<br>
<br>
please help me on this as i am not able to progress because of the lack of<br>
this understanding.<br>
<br>
Thanks and Regards,<br>
Gokul Vasan<br>

Hi Gokul,<br>
<br>
We have a userspace set of APIs called liblitmus. It is on github here: <a href="https://github.com/LITMUS-RT/liblitmus" target="_blank">https://github.com/LITMUS-RT/liblitmus</a><br>
<br>
The repository also includes sample applications and tools. To compile, make sure that liblitmus/ and litmus-rt/ are in the same shared directory. You may also want to read some of the documentation in the Litmus wiki: <a href="https://wiki.litmus-rt.org/litmus/" target="_blank">https://wiki.litmus-rt.org/litmus/</a><br>
<br>
Thank you for your interest in Litmus!<br>
<br>
-Glenn<br>
