Why would one want to install the -rt kernel if the aim is to save power by a tickless kernel?
After all, real-time kernels come with much harder constraints as to timing parameters while conventional kernels are more tolerant to delays. Certainly, you can draw a lot of benefits from latter by, say, grouping IRQs and writeback operations. Therefore, I somewhat doubt an RT kernel is less power consuming due to CONFIG_NO_HZ only, compared to a standard kernel with dynamic ticks disabled even. Also, I noticed that my Gutsy server's kernel image (2.6.22-14-server) does have CONFIG_NO_HZ set to yes, so what xknight said doesn't sound too reasonable to me. Is there some official statement regarding this issue? -- CONFIG_NO_HZ is not enabled https://bugs.launchpad.net/bugs/150018 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
