This is incredibly useful for debugging power management-related\nthings; however, having it as a compile-time option has proved to be\nincredibly inconvenient for us (OLPC). There are plenty of times that we\nwant serial console to not suspend, but for the most part we\u0027d like serial\nconsole to be suspended.\n\nThis drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel\nboot parameter (no_console_suspend). By default, the serial console will\nbe suspended along with the rest of the system; by passing\n\u0027no_console_suspend\u0027 to the kernel during boot, serial console will remain\nalive during suspend.\n\nFor now, this is pretty serial console specific; further fixes could be\napplied to make this work for things like netconsole.\n\nSigned-off-by: Andres Salomon \u003cdilinger@debian.org\u003e\nAcked-by: \"Rafael J.

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console device the\noutput goes to when the boot console stops printing messages.\n\nThe disable_early_printk() call is obsolete with that patch, explicitly\ndisabling the early console isn\u0027t needed any more as it works automagically\nwith that patch.\n\nI\u0027ve walked through the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.

Then you want to boot your kernel, and want to\noverride the default by passing console\u003db on the boot line. elilo constructs\nthe kernel cmdline by starting with the value of the global append line, then\ntacks on whatever else you specify, which puts console\u003db last.\n\nSigned-off-by: Greg Edwards \u003cedwardsg@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3c0547ba8b3bbd8b26ae35e33ac17ff51f67f78c", "tree": "e1986b120eb889f3a2ebc8887bd3b729880485ff", "parents": [ "e8f5bdb02ce06925e7fc5916125bdebc533d4299" ], "author": { "name": "Matt Mackall", "email": "mpm@selenic.com", "time": "Mon May 16 21:53:47 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Tue May 17 07:59:19 2005 -0700" }, "message": "[PATCH] add_preferred_console() build fix\n\nMove add_preferred_console out of CONFIG_PRINTK so serial console does the\nright thing.\n\nSigned-off-by: Matt Mackall \u003cmpm@selenic.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d59745ce3e7aa13856bca16d3bcbb95041775ff6", "tree": "6e495bb6697d86534685bf813c43e210a8d8323a", "parents": [ "cd7619d6bf36564cf54ff7218ef54e558a741913" ], "author": { "name": "Matt Mackall", "email": "mpm@selenic.com", "time": "Sun May 01 08:59:02 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sun May 01 08:59:02 2005 -0700" }, "message": "[PATCH] clean up kernel messages\n\nArrange for all kernel printks to be no-ops.
