One has to read the exec times of all\nthe tasks(/proc/\u003cpid\u003e/sched) in the group and add them. This method\nfails (or becomes difficult) if we want to collect stats of a group over\na duration where tasks get created and terminated.\n\nThis patch makes it easier to obtain group stats by directly including\nthem in /proc/sched_debug. Stats like group exec time would help user\nprograms (like LTP) to accurately measure the group fairness.\n\nAn example output of group stats from /proc/sched_debug:\n\ncfs_rq[3]:/3/a/1\n .exec_clock : 89.598007\n .MIN_vruntime : 0.000001\n .min_vruntime : 256300.970506\n .max_vruntime : 0.000001\n .spread : 0.000000\n .spread0 : -25373.372248\n .nr_running : 0\n .load : 0\n .yld_exp_empty : 0\n .yld_act_empty : 0\n .yld_both_empty : 0\n .yld_count : 4474\n .sched_switch : 0\n .sched_count : 40507\n .sched_goidle : 12686\n .ttwu_count : 15114\n .ttwu_local : 11950\n .bkl_count : 67\n .nr_spread_over : 0\n .shares : 0\n .se-\u003eexec_start : 113676.727170\n .se-\u003evruntime : 1592.612714\n .se-\u003esum_exec_runtime : 89.598007\n .se-\u003ewait_start : 0.000000\n .se-\u003esleep_start : 0.000000\n .se-\u003eblock_start : 0.000000\n .se-\u003esleep_max : 0.000000\n .se-\u003eblock_max : 0.000000\n .se-\u003eexec_max : 1.000282\n .se-\u003eslice_max : 1.999750\n .se-\u003ewait_max : 54.981093\n .se-\u003ewait_sum : 217.610521\n .se-\u003ewait_count : 50\n .se-\u003eload.weight : 2\n\nSigned-off-by: Bharata B Rao \u003cbharata@linux.vnet.ibm.com\u003e\nAcked-by: Srivatsa Vaddagiri \u003cvatsa@linux.vnet.ibm.com\u003e\nAcked-by: Dhaval Giani \u003cdhaval@linux.vnet.ibm.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "5ac5c4d604bf894ef672a7971d03fefdc7ea7e49", "tree": "ee7b71de46c0c71dec9e9ebb0efd2e66ce1c7a6d", "parents": [ "f7160c7573615ec82c691e294cf80d920b5d588d" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Mon Nov 10 10:46:32 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Nov 10 10:51:51 2008 +0100" }, "message": "sched: clean up debug info\n\nImpact: clean up and fix debug info printout\n\nWhile looking over the sched_debug code I noticed that we printed the rq\nschedstats for every cfs_rq, ammend this.\n\nAlso change nr_spead_over into an int, and fix a little buglet in\nmin_vruntime printing.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "0a0db8f5c9d4bbb9bbfcc2b6cb6bce2d0ef4d73d", "tree": "22a50ee7f1c5a4c6ae4a13c30b02c9faa52e0aa4", "parents": [ "eefd796a8e831408ce17e633d73d70430748c47a" ], "author": { "name": "Li Zefan", "email": "lizf@cn.fujitsu.com", "time": "Tue Nov 04 16:17:05 2008 +0800" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Nov 04 10:23:18 2008 +0100" }, "message": "sched debug: remove NULL checking in print_cfs/rt_rq()\n\nImpact: cleanup\n\ncfs-\u003etg is initialized in init_tg_cfs_entry() with tg !\u003d NULL, and\nwill never be invalidated to NULL.
