Xiangfu, excellent data points! Thanks! This confirms Lars prognosis that putting the Linux kernel inside a large ubifs would be a bad idea. In my opinion that data you collected means that:
*) We leave the Linux kernel outside of ubifs for now, in a flat partition. If we want to support multiple Linux kernel images, we need multiple such partitions (let's not do that right now). *) We will not increase the size of the 512 MB rootfs until we have tried some of the speed improvement ideas David proposed in IRC. The boot time is already 22 seconds now (with 512 MB rootfs and Linux kernel outside). I think that's high and we should see what we can do to bring it back down to 15 or so. 4 seconds for power-off is also too slow, that should be less than one second ideally. So let's try to bring the 22 seconds down first, before making changes to the location of the Linux kernel or rootfs size. Thanks again for the accurate data, Wolfgang _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
