I'm wondering whether we really want to do this ... and in turn wondering about the value of the "generic" vs. system specific config files and the whole machvec mechanism. If the config files is removed, then the occasional breakage that it finds will go unseen. How much does this matter? Not having it would speed by regression build sequence (sn2 takes the longest of all the builds I do). I primarily test tiger_defconfig kernels on Intel systems and zx1_defconfig kernels on HP systems ... with just the occasional boot test of a generic_defconfig kernel to make sure it hasn't been severely broken. Most end users are using distribution kernels ... which are based on generic kernels because distributors don't want to maintain a slew of separate binaries. Now there are possibly some performance benefits from using a platform specific kernel (reduced cpu usage because the indirection through machvec is eliminated, plus reduced memory footprint for the kernel). Has anyone ever tried to measure these? Are they worth the extra maintenance and testing needed to keep machvec alive? -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
