This is how I do 1G of mem on a /arch/ppc kernel. A short while (couple of weeks ago) I commented about thei s on a thread about setting up the TLB handlers on arch/powerpc, and asked if this was going to be possible to do, and basically got a resouding NO as answer. WHich means I'll be sticking to arch/ppc for a while yet. It would be nice to have this also working on arch/powerpc though. _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
