When a cpu gets\nofflined it schedules the idle process which, before killing its own cpu, will\ncall tick_nohz_stop_sched_tick(). That function in turn will call\nprintk_needs_cpu() in order to check if the local tick can be disabled. On\noffline cpus this function should naturally return 0 since regardless if the\ntick gets disabled or not the cpu will be dead short after. That is besides the\nfact that __cpu_disable() should already have made sure that no interrupts on\nthe offlined cpu will be delivered anyway.\n\nIn this case it prevents tick_nohz_stop_sched_tick() to call\nselect_nohz_load_balancer(). No idea if that really is a problem. However what\nmade me debug this is that on 2.6.32 the function get_nohz_load_balancer() is\nused within __mod_timer() to select a cpu on which a timer gets enqueued. If\nprintk_needs_cpu() returns 1 then the nohz_load_balancer cpu doesn\u0027t get\nupdated when a cpu gets offlined. It may contain the cpu number of an offline\ncpu. In turn timers get enqueued on an offline cpu and not very surprisingly\nthey never expire and cause system hangs.\n\nThis has been observed 2.6.32 kernels. On current kernels __mod_timer() uses\nget_nohz_timer_target() which doesn\u0027t have that problem. However there might be\nother problems because of the too early exit tick_nohz_stop_sched_tick() in\ncase a cpu goes offline.\n\nEasiest way to fix this is just to test if the current cpu is offline and call\nprintk_tick() directly which clears the condition.\n\nAlternatively I tried a cpu hotplug notifier which would clear the condition,\nhowever between calling the notifier function and printk_needs_cpu() something\ncould have called printk() again and the problem is back again.

This is normally tty (assuming\nCONFIG_VT_CONSOLE is enabled, which it commonly is).\n\nThis is okay as long tty is a useful console. But unless we have the\nPV framebuffer, and it is enabled for this domain, tty0 in domU is\nmerely a dummy. In that case, we want the preferred console to be the\nXen console hvc0, and we want it without having to fiddle with the\nkernel command line. Commit b8c2d3dfbc117dff26058fbac316b8acfc2cb5f7\ndid that for us.\n\nSince we now have the PV framebuffer, we want to enable and prefer tty\nagain, but only when PVFB is enabled. But even then we still want to\nenable the Xen console as well.\n\nProblem: when tty registers, we can\u0027t yet know whether the PVFB is\nenabled. By the time we can know (xenstore is up), the console setup\ngame is over.\n\nSolution: enable console tty by default, but keep hvc as the preferred\nconsole. Change the preferred console to tty when PVFB probes\nsuccessfully, unless we\u0027ve been given console kernel parameters.\n\nSigned-off-by: Markus Armbruster \u003carmbru@redhat.com\u003e\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "091593080533a752ce66d12858d8c4105c8e1793", "tree": "de8793133104a9a19bbba971d3bfb84408e4cdbb", "parents": [ "ac60ad7413ca8208094609a3b88ed9b1ed012fbc" ], "author": { "name": "Nick Andrew", "email": "nick@nick-andrew.net", "time": "Mon May 12 21:21:04 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Sat May 24 23:15:19 2008 +0200" }, "message": "printk: remember the message level for multi-line output\n\nprintk(KERN_ALERT \"Danger Will Robinson!\\nAlien Approaching!\\n\");\n\nAt present this will result in one message at ALERT level and one\nat the current default message loglevel (e.g. WARNING).
