Forwarding again as this patch didn't make it to lse-tech, ckrm-tech and elsa-devel. Please include Andrew Morton and lkml on replies. -- Shailabh
-------- Original Message -------- Subject: [Patch 0/6] Per-task delay accounting Date: Tue, 03 Jan 2006 23:16:40 +0000 From: Shailabh Nagar <[EMAIL PROTECTED]> To: Andrew Morton <[EMAIL PROTECTED]>, linux-kernel <linux-kernel@vger.kernel.org> CC: elsa-devel <[EMAIL PROTECTED]>, LSE <[EMAIL PROTECTED]>, ckrm-tech <ckrm-tech@lists.sourceforge.net> Andrew, Could you please consider these patches for inclusion in -mm ? The comments from earlier postings of these patches have been addressed, including the one you made about making the connector interface generic (more about that in the connector patch). Thanks, Shailabh The following patches add accounting for the delays seen by tasks in a) waiting for a CPU (while being runnable) b) completion of synchronous block I/O initiated by the task c) swapping in pages (i.e. capacity misses). Such delays provide feedback for a task's cpu priority, io priority and rss limit values. Long delays, especially relative to other tasks, can be a trigger for changing a task's cpu/io priorities and modifying its rss usage (either directly through sys_getprlimit() that was proposed earlier on lkml or by throttling cpu consumption or process calling sys_setrlimit etc.) The major change since the previous posting of these patches (http://www.ussg.iu.edu/hypermail/linux/kernel/0512.0/2152.html) is the resurrection of the connector interface (in addition to /proc) and, as part of the same patch, the ability to get stats per-tgid in addition to per-pid. More comments in individual patches.
