Hi, We have a MPC7448 based board with 2.6.21 ported (ppc arch). We want to apply the PREEPMT_RT patch to the existing kernel and drivers. Well, it turns out to be a difficult task since the ppc arch doesn't seem to support the RT patch very well. Has anyone had a working 2.6.21+ kernel with RT patch for the ppc arch? Is the ppc arch just dying?
I may have two choices. One is to move to the powerpc arch that is actively developed and has proven working RT patches from the community. This will force us to migrate our drivers to a newer kernel and a new arch, which is certainly not trivial. The other is to back port an existing and working RT patch to the ppc arch of 2.6.21, which, at least for now, seems quite difficult and may not be merited for future. I'm soliciting comments from the community. Thanks in advance for sharing your thoughts. -Ryan. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
