None that I know of. I imagine that I'm the only person who has ever done this. There are some conflicts (a few are non-trivial, but not excessively complicated, IIRC). But it's not something insurmountable. You do have to have a fairly good understanding of kernel code. -corey > > > Thanks > zmau > -- > To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 6+ messages in thread

I would assume that more than one person would have such an experience. I am curious regarding the magnitude of work to be done. I am especially intersted what happens when you have to handle another Linux version for your distribution. Is this job done just once (for one specific Linux version) ? or You do the job once, and then do the same fixes on the other Linux version (more or less) ? or You have to do the same job all over again in every linux version ? Is the following discription correct ? Basically the job is 1) Download kernel 2) apply RT-patch 3) apply PAX patch 4) compile and fix warnings and errors Thanks again zmau On Thu, May 1, 2014 at 2:53 AM, Corey Minyard <cminyard@mvista.com> wrote: > On 04/30/2014 05:47 PM, Mau Z wrote: >> I have some more questions concerning the relation between PAX and the >> RT-Patch : >> A) Can they work together ? > > It can be made to work.

But basically yes. Resolving the conflicts is the biggest deal, really, in the above process. And testing is a lot bigger than that :). We integrate a lot of other things, so it's hard to remember the specific RT/PaX issues. -corey > > Thanks > again > zmau > > > On Thu, May 1, 2014 at 2:53 AM, Corey Minyard <cminyard@mvista.com> wrote: >> On 04/30/2014 05:47 PM, Mau Z wrote: >>> I have some more questions concerning the relation between PAX and the >>> RT-Patch : >>> A) Can they work together ? >> It can be made to work.
