It seems to me that this issue has certain parallels to the current and long running debate about linux kernel power management hacks targeting embedded devices (e.g. android wake locks) Specifically -- applications are very frequently crappy, and fixing them all, or even a significant fraction of them, is significantly unlikely. Ergo, what, if anything, could a linux kernel do to reign in misbehaving apps? Android's answer is to sleep regardless of what the apps say, with a privilege limited mechanism that blocks sleeping. Privs are only granted to apps the admin (or android packager) deems truely critical like the radio / phone apps. Would some similar sort of mechanism help for virtualization? (complete, uninformed speculation here) Perhaps a kernel mechanism to limit wakeups in the case that no cpu is seen to be consumed, or the like? - -- Pat -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxrBHsACgkQNObCqA8uBswOzwCeN8Sdm59uWxiJXRJiYT60FYX7 4h8AnixYLgrj2+uGx4O2DgD4yI9ornI+ =0pfK -----END PGP SIGNATURE----- ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
