Re: Inquiry: Should we remove "isolcpus= kernel boot option? (may have realtime uses)

Dear Michael Trimarchi,

Recently, I read your paper about EDF implementation  in Linux  like belows.

http://feanor.sssup.it/~marko/SAC09.pdf
(An implementation of the earliest deadline first algorithm in Linux
Proceedings of the 2009 ACM symposium on Applied Computing. )

Can I get your 2.6.27 based EDF patch to  test your experiment result ?
Thanks reading.


Regards,
GeunSik, Lim
