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).

The implementation has some flaws though. The major\nproblem is that presence of a boot console makes register_console() ignore\nany other console devices (unless explicitly specified on the kernel\ncommand line).\n\nThis patch fixes the console selection code to *not* consider a boot\nconsole a full-featured one, so the first non-boot console registering will\nbecome the default console instead. This way the unregister call for the\nboot console in the register_console() function actually triggers and the\nhandover from the boot console to the real console device works smoothly.\nAdded a printk for the handover, so you know which console device the\noutput goes to when the boot console stops printing messages.\n\nThe disable_early_printk() call is obsolete with that patch, explicitly\ndisabling the early console isn\u0027t needed any more as it works automagically\nwith that patch.\n\nI\u0027ve walked through the tree, dropped all disable_early_printk() instances\nfound below arch/ and tagged the consoles with CON_BOOT if needed. The\ncode is tested on x86, sh (thanks to Paul) and mips (thanks to Ralf).\n\nChanges to last version: Rediffed against -rc3, adapted to mips cleanups by\nRalf, fixed \"udbg-immortal\" cmd line arg on powerpc.\n\nSigned-off-by: Gerd Hoffmann \u003ckraxel@exsuse.de\u003e\nAcked-by: Paul Mundt \u003clethal@linux-sh.org\u003e\nAcked-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0bbfb7c2e4b682542a822d3af05cea0e5cb5ba81", "tree": "db9b43adbcf1c7fa02e68a04fe1f914d23c3cd4b", "parents": [ "a8e14b950c9a9e2ec703df610e00ae8581040517" ], "author": { "name": "Patrick Pletscher", "email": "pat@pletscher.org", "time": "Sat Feb 17 20:10:16 2007 +0100" }, "committer": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Sat Feb 17 20:10:16 2007 +0100" }, "message": "kernel/printk.c: comment fix\n\nSigned-off-by: Patrick Pletscher \u003cpat@pletscher.org\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\n" }, { "commit": "1efc5da3cf567d2f6b795f9d2112ed97fec4ee7c", "tree": "25a45ed5a45e5ad54c6264240cd3c55e751858b3", "parents": [ "482a579b370a0bf924b577efd6c750284a95e0fb" ], "author": { "name": "Mathieu Desnoyers", "email": "compudj@krystal.dyndns.org", "time": "Sat Feb 10 01:46:29 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Sun Feb 11 11:18:06 2007 -0800" }, "message": "[PATCH] order of lockdep off/on in vprintk() should be changed\n\nThe order of locking between lockdep_off/on() and local_irq_save/restore() in\nvprintk() should be changed.\n\n* In kernel/printk.c :\n\nvprintk() does :\n\npreempt_disable()\nlocal_irq_save()\nlockdep_off()\nspin_lock(\u0026logbuf_lock)\nspin_unlock(\u0026logbuf_lock)\nif(!down_trylock(\u0026console_sem))\n up(\u0026console_sem)\nlockdep_on()\nlocal_irq_restore()\npreempt_enable()\n\nThe goals here is to make sure we do not call printk() recursively from\nkernel/lockdep.c:__lock_acquire() (called from spin_* and down/up) nor from\nkernel/lockdep.c:trace_hardirqs_on/off() (called from local_irq_restore/save).\nIt can then potentially call printk() through mark_held_locks/mark_lock.\n\nIt correctly protects against the spin_lock call and the up/down call, but it\ndoes not protect against local_irq_restore.
