This shift has caused a whole bunch of\ncompile problems under different config options. I attempt to\nsimplify things with the patch below.\n\nIn order to simplify things, I had to come to terms with the\nmeaning of two terms ARCH_HAS_NMI_WATCHDOG and\nCONFIG_HARDLOCKUP_DETECTOR. Basically they mean the same thing,\nthe former on a local level and the latter on a global level.\n\nWith the old x86 nmi watchdog gone, there is no need to rely on\ndefining the ARCH_HAS_NMI_WATCHDOG variable because it doesn\u0027t\nmake sense any more. x86 will now use the global\nimplementation.\n\nThe changes below do a few things. First it changes the few\nplaces that relied on ARCH_HAS_NMI_WATCHDOG to use\nCONFIG_X86_LOCAL_APIC (the former was an alias for the latter\nanyway, so nothing unusual here). Those pieces of code were\nrelying more on local apic functionality the nmi watchdog\nfunctionality, so the change should make sense.\n\nSecond, I removed the x86 implementation of\ntouch_nmi_watchdog(). It isn\u0027t need now, instead x86 will rely\non kernel/watchdog.c\u0027s implementation.\n\nThird, I removed the #define ARCH_HAS_NMI_WATCHDOG itself from\nx86. And tweaked the include/linux/nmi.h file to tell users to\nlook for an externally defined touch_nmi_watchdog in the case of\nARCH_HAS_NMI_WATCHDOG _or_ CONFIG_HARDLOCKUP_DETECTOR. This\nchanges removes some of the ugliness in that file.\n\nFinally, I added a Kconfig dependency for\nCONFIG_HARDLOCKUP_DETECTOR that said you can\u0027t have\nARCH_HAS_NMI_WATCHDOG _and_ CONFIG_HARDLOCKUP_DETECTOR. You can\nonly have one nmi_watchdog.\n\nTested with\nARCH\u003di386: allnoconfig, defconfig, allyesconfig, (various broken\nconfigs) ARCH\u003dx86_64: allnoconfig, defconfig, allyesconfig,\n(various broken configs)\n\nHopefully, after this patch I won\u0027t get any more compile broken\nemails. :-)\n\nv3:\n changed a couple of \u0027linux/nmi.h\u0027 -\u003e \u0027asm/nmi.h\u0027 to pick-up correct function\n prototypes when CONFIG_HARDLOCKUP_DETECTOR is not set.\n\nSigned-off-by: Don Zickus \u003cdzickus@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: fweisbec@gmail.com\nLKML-Reference: \u003c1293044403-14117-1-git-send-email-dzickus@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "96a84c20d635fb1e98ab92f9fc517c4441f5c424", "tree": "0bbc7fef23879f1f468e4521ca22bb0585a001ac", "parents": [ "2c6cb1053ad8b61ab9fb50b578d0ffea959f7583" ], "author": { "name": "Don Zickus", "email": "dzickus@redhat.com", "time": "Mon Nov 29 17:07:16 2010 -0500" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Dec 10 00:01:06 2010 +0100" }, "message": "lockup detector: Compile fixes from removing the old x86 nmi watchdog\n\nMy patch that removed the old x86 nmi watchdog broke other\narches.

Frustratingly,\nadding printks or function tracing to the ACPI code made the hangs go away\n...\n\nAfter some time an additional detail emerged: disabling the NMI watchdog\nmade these occasional hangs go away.\n\nSo i spent the better part of today trying to debug this and trying out\nvarious theories when i finally found the likely reason for the hang: if\nacpi_ns_initialize_devices() executes an _INI AML method and an NMI\nhappens to hit that AML execution in the wrong moment, the machine would\nhang. (my theory is that this must be some sort of chipset setup method\ndoing stores to chipset mmio registers?)\n\nUnfortunately given the characteristics of the hang it was sheer\nimpossible to figure out which of the numerous AML methods is impacted\nby this problem.\n\nAs a workaround i wrote an interface to disable chipset-based NMIs while\nexecuting _INI sections - and indeed this fixed the hang. I did a\nboot-loop of 100 separate reboots and none hung - while without the patch\nit would hang every 5-10 attempts. Out of caution i did not touch the\nnmi_watchdog\u003d2 case (it\u0027s not related to the chipset anyway and didnt\nhang).\n\nI implemented this for both x86_64 and i686, tested the i686 laptop both\nwith nmi_watchdog\u003d1 [which triggered the hangs] and nmi_watchdog\u003d2, and\ntested an Athlon64 box with the 64-bit kernel as well. Everything builds\nand works with the patch applied.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Len Brown \u003clenb@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n" }, { "commit": "bb81a09e55eaf7e5f798468ab971469b6f66a259", "tree": "cf1ed6b0ad75137361228955535044fd4630a57b", "parents": [ "e5e3a0428968dcc1f9318ce1c941a918e99f8b84" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Thu Dec 07 02:14:01 2006 +0100" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Thu Dec 07 02:14:01 2006 +0100" }, "message": "[PATCH] x86: all cpu backtrace\n\nWhen a spinlock lockup occurs, arrange for the NMI code to emit an all-cpu\nbacktrace, so we get to see which CPU is holding the lock, and where.\n\nCc: Andi Kleen \u003cak@muc.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n" }, { "commit": "9938406ab6b2558d60c0c7200cc8e12f1ea7104a", "tree": "2c0e7f9200253bca62cef833ba5405bdf5032351", "parents": [ "df89a864631f5d840f4873c4c03733b4206e78ea" ], "author": { "name": "Michal Schmidt", "email": "xschmi00@stud.feec.vutbr.cz", "time": "Fri Sep 29 01:59:03 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:05 2006 -0700" }, "message": "[PATCH] Make touch_nmi_watchdog imply touch_softlockup_watchdog on all archs\n\ntouch_nmi_watchdog() calls touch_softlockup_watchdog() on both\narchitectures that implement it (i386 and x86_64).
