When, CONFIG_DYNAMIC_PRINTK_DEBUG,\nis not set, debugging statements can still be enabled as before, often by\ndefining \u0027DEBUG\u0027 for the proper compilation unit. Thus, this patch set has no\naffect when CONFIG_DYNAMIC_PRINTK_DEBUG is not set.\n\nThe infrastructure currently ties into all pr_debug() and dev_dbg() calls. That\nis, if CONFIG_DYNAMIC_PRINTK_DEBUG is set, all pr_debug() and dev_dbg() calls\ncan be dynamically enabled/disabled on a per-module basis.\n\nFuture plans include extending this functionality to subsystems, that define \ntheir own debug levels and flags.\n\nUsage:\n\nDynamic debugging is controlled by the debugfs file, \n\u003cdebugfs\u003e/dynamic_printk/modules. This file contains a list of the modules that\ncan be enabled. The format of the file is as follows:\n\n\t\u003cmodule_name\u003e \u003cenabled\u003d0/1\u003e\n\t\t.\n\t\t.\n\t\t.\n\n\t\u003cmodule_name\u003e : Name of the module in which the debug call resides\n\t\u003cenabled\u003d0/1\u003e : whether the messages are enabled or not\n\nFor example:\n\n\tsnd_hda_intel enabled\u003d0\n\tfixup enabled\u003d1\n\tdriver enabled\u003d0\n\nEnable a module:\n\n\t$echo \"set enabled\u003d1 \u003cmodule_name\u003e\" \u003e dynamic_printk/modules\n\nDisable a module:\n\n\t$echo \"set enabled\u003d0 \u003cmodule_name\u003e\" \u003e dynamic_printk/modules\n\nEnable all modules:\n\n\t$echo \"set enabled\u003d1 all\" \u003e dynamic_printk/modules\n\nDisable all modules:\n\n\t$echo \"set enabled\u003d0 all\" \u003e dynamic_printk/modules\n\nFinally, passing \"dynamic_printk\" at the command line enables\ndebugging for all modules.

"sched_rt.c: resch needed in rt_rq_enqueue() for the root rt_rq\n\nWhile working on the new version of the code for SCHED_SPORADIC I\nnoticed something strange in the present throttling mechanism. More\nspecifically in the throttling timer handler in sched_rt.c\n(do_sched_rt_period_timer()) and in rt_rq_enqueue().\n\nThe problem is that, when unthrottling a runqueue, rt_rq_enqueue() only\nasks for rescheduling if the runqueue has a sched_entity associated to\nit (i.e., rt_rq-\u003ert_se !\u003d NULL).\nNow, if the runqueue is the root rq (which has a rt_se \u003d NULL)\nrescheduling does not take place, and it is delayed to some undefined\ninstant in the future.\n\nThis imply some random bandwidth usage by the RT tasks under throttling.\nFor instance, setting rt_runtime_us/rt_period_us \u003d 950ms/1000ms an RT\ntask will get less than 95%. In our tests we got something varying\nbetween 70% to 95%.\nUsing smaller time values, e.g., 95ms/100ms, things are even worse, and\nI can see values also going down to 20-25%!!\n\nThe tests we performed are simply running \u0027yes\u0027 as a SCHED_FIFO task,\nand checking the CPU usage with top, but we can investigate thoroughly\nif you think it is needed.\n\nThings go much better, for us, with the attached patch... Don\u0027t know if\nit is the best approach, but it solved the issue for us.\n\nSigned-off-by: Dario Faggioli \u003craistlin@linux.it\u003e\nSigned-off-by: Michael Trimarchi \u003ctrimarchimichael@yahoo.it\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "07454bfff151d2465ada809bbaddf3548cc1097c", "tree": "fae1802b291e57c0376f9deddcbd8bf539587940", "parents": [ "2165f631f0e1d4e9a1ee425ef05cb727352285e0" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Sat Oct 04 10:51:07 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Sat Oct 04 10:51:07 2008 +0200" }, "message": "clockevents: check broadcast tick device not the clock events device\n\nImpact: jiffies increment too fast.\n\nHugh Dickins noted that with NOHZ\u003dn and HIGHRES\u003dn jiffies get\nincremented too fast.
