&nbsp;&nbsp;&nbsp; an interesting proposal.&nbsp; I think that most of the LNG steering 
committee is on this alias, but just in case, I'm adding them to it...<br>

our investigations into the Linux scheduler we've<br>interacted with 
Juri Lelli at the University of Pisa (cc'ed) who is<br>part of a group 
that is working on a DEADLINE scheduler[1] for<br>Linux[2].<br><br>While
 we're coming at this from a power managment angle[3], I suspect<br>that
 LEG and LNG already have real-world usecases that would benefit<br>from
 deadline scheduler found in other RTOSes.<br><br>So I think it makes 
sense to merge Juri's tree into linux-linaro going<br>forward to allow 
easier experimentation. Does LEG and LNG have any<br>interest in this at
 this point?<br><br>Juri has expressed an interest in maintaining a 
current branch of the<br>code that could be merged into our monthly 
release. In return, real<br>world usecases will improve his chances of 
getting the code merged<br>into mainline.<br><br>Regards,<br>Amit<br><br>[1]
