Re: [uClinux-dev] kernel preemptible on m68knommu ?
Hi, I think preemtible characteristic is especific for a 2.6.x kernel. Which kernel branch are you testing? Regards, En/na [EMAIL PROTECTED] ha escrit: hi all, i am looking to have a kernel that is preemptible. I use a Coldfire 5271, so it is in the family m68knommu. I search the CONFIG_PREEMPT option in the kernel and did not found it. So i take a look in the code, and i don't find anything for the m68knommu. i search on different architectur, so i found that nios2 or m68k have something in it to take care of the CONFIG_PREEMPT define. Is the work difficult to port the preemptible kernel from m68k to m68knommu ? Has someone a patch for the m68knommu arch so my kernel is preemtible ? My application need to respond quickly on some interruption, but i can't do the application in a driver. Is there another solution that have a preemptible kernel to achieve the aim ? I was thinking about calling schedule() in the interrupt hanlder, but it seem very bad ? But how can the scheduler be called just after the interruption ?

As far as I know noone has added this yet for m68knommu. Should be nice to have it added :-) Regards Greg i search on different architectur, so i found that nios2 or m68k have something in it to take care of the CONFIG_PREEMPT define.
