https://bugzilla.novell.com/show_bug.cgi?id=403690 Summary: ioprio root only (beagle) ... Product: openSUSE 11.0 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: mmeeks@novell.com QAContact: qa@suse.de CC: agruen@novell.com Found By: --- One of the main pains with beagle (and tracker) is the latency and system-halting effects they cause even at low nice levels due to them swallowing ~all the I/O resources. The ioprio_set syscall was used to help out here - pulling beagle right, right down the priority queue - in a way that is hard to simulate in user-space: http://svn.gnome.org/viewvc/beagle/trunk/beagle/glue/ioprio-glue.c?revision=3292&view=markup Unfortunately - it seems ioprio_set for IDLE turned into a "root only" system-call making it useless for us. A similar Ubuntu bug is here: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/138846 AFAIR there was a kernel thread on this, the pointer for which I've lost and can't find. It seems strange not to let a user downgrade his own process' IO priority to IDLE. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
