I know this is nitpicky, but I noticed that the kernel seems to be trying to balance/reschedule interrupts when there are none. This makes the arch_timer create hundreds of thousands-millions of interrupts per cpu core for no reason.
Any way to compile the kernel to be tickless? Being a pretty much single purpose OS PiCore is not likely to have many processes to reschedule in the first place. CONFIG_NO_HZ_FULL will enable the "full" tickless mode. And/Or, make it an option in the "bootcodes" menu 36987 +-------------------------------------------------------------------+ |Filename: kerneltick.png | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=36987| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ edwardthern's Profile: http://forums.slimdevices.com/member.php?userid=66099 View this thread: http://forums.slimdevices.com/showthread.php?t=114828 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
