"zImage" is just a container file for the current compressed kernel image, it can also hold an uncompressed image. However your are forgetting one little detail. It's not just the "uncompression" time, you also have the image "load" time.. There is a good blog post here: http://free-electrons.com/blog/arm-xz-kernel-decompression-benchmarks/ Currently we are using: CONFIG_KERNEL_XZ https://github.com/RobertCNelson/linux-dev/blob/am33x-v3.8/patches/defconfig#L39 you might see a small reduction from: CONFIG_KERNEL_LZO Post 3.11, take a look at lz4 http://events.linuxfoundation.org/sites/events/files/lcjpcojp13_klee.pdf Regards, -- Robert Nelson http://www.rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
