Impact: Higher priority bug fix The machine check poller runs a single timer and then broadcasted an IPI to all CPUs to check them. This leads to unnecessary synchronization between CPUs. The original CPU running the timer has to wait potentially a long time for all other CPUs answering. This is also real time unfriendly and in general inefficient. This was especially a problem on systems with a lot of events where the poller run with a higher frequency after processing some events. There could be more and more CPU time wasted with this, to the point of significantly slowing down machines. The machine check polling is actually fully independent per CPU, so there's no reason to not just do this all with per CPU timers. This patch implements that. Also switch the poller also to use standard timers instead of work queues. It was using work queues to be able to execute a user program on a event, but mce_notify_user() handles this case now with a separate callback. So instead always run the poll code in in a standard per CPU timer, which means that in the common case of not having to execute a trigger there will be less overhead. This allows to clean up the initialization significantly, because standard timers are already up when machine checks get init'ed. No multiple initialization functions. Thanks to Thomas Gleixner for some help.

Impact: Needed for bug fix in next patch This relaxes the requirement that mce_notify_user has to run in process context. Useful for future changes, but also leads to cleaner behaviour now. Now instead mce_notify_user can be called directly from interrupt (but not NMI) context. The work queue only uses a single global work struct, which can be done safely because it is always free to reuse before the trigger function is executed. This way no events can be lost.

Impact: low priority bug fix This removes part of a a patch I added myself some time ago. After some consideration the patch was a bad idea. In particular it stopped machine check exceptions during code patching. To quote the comment: * MCEs only happen when something got corrupted and in this * case we must do something about the corruption. * Ignoring it is worse than a unlikely patching race. * Also machine checks tend to be broadcast and if one CPU * goes into machine check the others follow quickly, so we don't * expect a machine check to cause undue problems during to code * patching. So undo the machine check related parts of 8f4e956b NMIs are still disabled. This only removes code, the only additions are a new comment.

Impact: Bug fix During suspend it is not reliable to process machine check exceptions, because CPUs disappear but can still get machine check broadcasts. Also the system is slightly more likely to machine check them, but the handler is typically not a position to handle them in a meaningfull way. So disable them during suspend and enable them during resume. Also make sure they are always disabled on hot-unplugged CPUs. This new code assumes that suspend always hotunplugs all non BP CPUs. v2: Remove the WARN_ONs Thomas objected to.

Impact: fix disabled MCE after resume Don't prevent multiple initialization of MCEs. Back from early prehistory mcheck_init() has a reentry check. Presumably that was needed in very old kernels to prevent it entering twice.

During CPU hot-remove the sysfs directory created by threshold_create_bank(), defined in arch/x86/kernel/cpu/mcheck/mce_amd_64.c, has to be removed before its parent directory, created by mce_create_device(), defined in arch/x86/kernel/cpu/mcheck/mce_64.c . Moreover, when the CPU in question is hotplugged again, obviously the latter has to be created before the former. At present, the right ordering is not enforced, because all of these operations are carried out by CPU hotplug notifiers which are not appropriately ordered with respect to each other. This leads to serious problems on systems with two or more multicore AMD CPUs, among other things during suspend and hibernation. Fix the problem by placing threshold bank CPU hotplug callbacks in mce_cpu_callback(), so that they are invoked at the right places, if defined. Additionally, use kobject_del() to remove the sysfs directory associated with the kobject created by kobject_create_and_add() in threshold_create_bank(), to prevent the kernel from crashing during CPU hotplug operations on systems with two or more multicore AMD CPUs.

This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections.

Use alternatives to select the workaround for the 11AP Pentium erratum for the affected steppings on the fly rather than build time. Remove the X86_GOOD_APIC configuration option and replace all the calls to apic_write_around() with plain apic_write(), protecting accesses to the ESR as appropriate due to the 3AP Pentium erratum. Remove apic_read_around() and all its invocations altogether as not needed. Remove apic_write_atomic() and all its implementing backends. The use of ASM_OUTPUT2() is not strictly needed for input constraints, but I have used it for readability's sake. I had the feeling no one else was brave enough to do it, so I went ahead and here it is. Verified by checking the generated assembly and tested with both a 32-bit and a 64-bit configuration, also with the 11AP "feature" forced on and verified with gdb on /proc/kcore to work as expected (as an 11AP machines are quite hard to get hands on these days). Some script complained about the use of "volatile", but apic_write() needs it for the same reason and is effectively a replacement for writel(), so I have disregarded it. I am not sure what the policy wrt defconfig files is, they are generated and there is risk of a conflict resulting from an unrelated change, so I have left changes to them out. The option will get removed from them at the next run. Some testing with machines other than mine will be needed to avoid some stupid mistake, but despite its volume, the change is not really that intrusive, so I am fairly confident that because it works for me, it will everywhere.

Eliminate the 6 bank restriction in 64 bit mce reporting code. This restriction is artificial (due to static creation of sysfs files) and 32 bit code does not have any such restriction. This change helps in reporting the details of machine checks on a machine check exception with errors in bank 6 and above on CPUs that support those banks. Without the patch, machine check errors in those banks are not reported. We still have 128 (MCE_EXTENDED_BANK) bank restriction instead of max 256 supported in hardware. That is not changed in the patch below as it will have some user level mcelog utility dependency, with bank 128 being used for thermal reporting currently. The patch below does not create sysfs control (bankNctl) for banks higher than 6 as well. That needs some pre-cleanup in /sysfs mce layout, removal of per cpu /sysfs entries for bankctl as they are really global system level control today. That change will follow. This basic change is critical to report the detailed errors on banks higher than 6. Signed-off-by: NVenkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
