Having a counter\ncompare register which generates an interrupt on matching values\nforces the software to do at least one superfluous readback of the\ncounter register.\n\nWhile it is nice in theory to program \"absolute\" time events it is\npractically useless because the timer runs at some absurd frequency\nwhich can never be matched to real world units. So we are forced to\ncalculate a relative delta and this forces a readout of the actual\ncounter value, adding the delta and programming the compare\nregister. When the delta is small enough we run into the danger that\nwe program a compare value which is already in the past. Due to the\ncompare for equal nature of HPET we need to read back the counter\nvalue after writing the compare rehgister (btw. this is necessary for\nabsolute timeouts as well) to make sure that we did not miss the timer\nevent. We try to work around that by setting the minimum delta to a\nvalue which is larger than the theoretical time which elapses between\nthe counter readout and the compare register write, but that\u0027s only\ntrue in theory. A NMI or SMI which hits between the readout and the\nwrite can easily push us beyond that limit. This would result in\nwaiting for the next HPET timer interrupt until the 32bit wraparound\nof the counter happens which takes about 306 seconds.\n\nSo we designed the next event function to look like:\n\n match \u003d read_cnt() + delta;\n write_compare_ref(match);\n return read_cnt() \u003c match ? 0 : -ETIME;\n\nAt some point we got into trouble with certain ATI chipsets. Even the\nabove \"safe\" procedure failed. The reason was that the write to the\ncompare register was delayed probably for performance reasons. The\ntheory was that they wanted to avoid the synchronization of the write\nwith the HPET clock, which is understandable. So the write does not\nhit the compare register directly instead it goes to some intermediate\nregister which is copied to the real compare register in sync with the\nHPET clock. That opens another window for hitting the dreaded \"wait\nfor a wraparound\" problem.\n\nTo work around that \"optimization\" we added a read back of the compare\nregister which either enforced the update of the just written value or\njust delayed the readout of the counter enough to avoid the issue. We\nunfortunately never got any affirmative info from ATI/AMD about this.\n\nOne thing is sure, that we nuked the performance \"optimization\" that\nway completely and I\u0027m pretty sure that the result is worse than\nbefore some HW folks came up with those.\n\nJust for paranoia reasons I added a check whether the read back\ncompare register value was the same as the value we wrote right\nbefore. That paranoia check triggered a couple of years after it was\nadded on an Intel ICH9 chipset. Venki added a workaround (commit\n8da854c) which was reading the compare register twice when the first\ncheck failed. We considered this to be a penalty in general and\nrestricted the readback (thus the wasted CPU cycles) to the known to\nbe affected ATI chipsets.\n\nThis turned out to be a utterly wrong decision. 2.6.35 testers\nexperienced massive problems and finally one of them bisected it down\nto commit 30a564be which spured some further investigation.\n\nFinally we got confirmation that the write to the compare register can\nbe delayed by up to two HPET clock cycles which explains the problems\nnicely. All we can do about this is to go back to Venki\u0027s initial\nworkaround in a slightly modified version.\n\nJust for the record I need to say, that all of this could have been\navoided if hardware designers and of course the HPET committee would\nhave thought about the consequences for a split second. It\u0027s out of my\ncomprehension why designing a working timer is so hard. There are two\nways to achieve it:\n\n 1) Use a counter wrap around aware compare_reg \u003c\u003d counter_reg\n implementation instead of the easy compare_reg \u003d\u003d counter_reg\n\n Downsides:\n\n\t- It needs more silicon.\n\n\t- It needs a readout of the counter to apply a relative\n\t timeout. This is necessary as the counter does not run in\n\t any useful (and adjustable) frequency and there is no\n\t guarantee that the counter which is used for timer events is\n\t the same which is used for reading the actual time (and\n\t therefor for calculating the delta)\n\n Upsides:\n\n\t- None\n\n 2) Use a simple down counter for relative timer events\n\n Downsides:\n\n\t- Absolute timeouts are not possible, which is not a problem\n\t at all in the context of an OS and the expected\n\t max. latencies/jitter (also see Downsides of #1)\n\n Upsides:\n\n\t- It needs less or equal silicon.\n\n\t- It works ALWAYS\n\n\t- It is way faster than a compare register based solution (One\n\t write versus one write plus at least one and up to four\n\t reads)\n\nI would not be so grumpy about all of this, if I would not have been\nignored for many years when pointing out these flaws to various\nhardware folks. I really hate timers (at least those which seem to be\ndesigned by janitors).\n\nThough finally we got a reasonable explanation plus a solution and I\nwant to thank all the folks involved in chasing it down and providing\nvaluable input to this.\n\nBisected-by: Nix \u003cnix@esperi.org.uk\u003e\nReported-by: Artur Skawina \u003cart.08.09@gmail.com\u003e\nReported-by: Damien Wyart \u003cdamien.wyart@free.fr\u003e\nReported-by: John Drescher \u003cdrescherjm@gmail.com\u003e\nCc: Venkatesh Pallipadi \u003cvenki@google.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: H.

These crashes are caused by\nAMD Erratum 383 and result in a fatal machine check exception. Here\u0027s\nthe scenario:\n\n1. On 32-bit, the swapper_pg_dir page table is used as the initial page\ntable for booting a secondary CPU.\n\n2. To make this work, swapper_pg_dir needs a direct mapping of physical\nmemory in it (the low mappings). By adding those low, large page (2M)\nmappings (PAE kernel), we create the necessary conditions for Erratum\n383 to occur.\n\n3. Other CPUs which do not participate in the off- and onlining game may\nuse swapper_pg_dir while the low mappings are present (when leave_mm is\ncalled). For all steps below, the CPU referred to is a CPU that is using\nswapper_pg_dir, and not the CPU which is being onlined.\n\n4. The presence of the low mappings in swapper_pg_dir can result\nin TLB entries for addresses below __PAGE_OFFSET to be established\nspeculatively. These TLB entries are marked global and large.\n\n5. When the CPU with such TLB entry switches to another page table, this\nTLB entry remains because it is global.\n\n6. The process then generates an access to an address covered by the\nabove TLB entry but there is a permission mismatch - the TLB entry\ncovers a large global page not accessible to userspace.\n\n7. Due to this permission mismatch a new 4kb, user TLB entry gets\nestablished. Further, Erratum 383 provides for a small window of time\nwhere both TLB entries are present. This results in an uncorrectable\nmachine check exception signalling a TLB multimatch which panics the\nmachine.\n\nThere are two ways to fix this issue:\n\n 1. Always do a global TLB flush when a new cr3 is loaded and the\n old page table was swapper_pg_dir. I consider this a hack hard\n to understand and with performance implications\n\n 2. Do not use swapper_pg_dir to boot secondary CPUs like 64-bit\n does.\n\nThis patch implements solution 2. It introduces a trampoline_pg_dir\nwhich has the same layout as swapper_pg_dir with low_mappings. This page\ntable is used as the initial page table of the booting CPU. Later in the\nbringup process, it switches to swapper_pg_dir and does a global TLB\nflush.

Unfortunately\nmp_register_ioapic did just a little more than the previous\nhand crafted code and so we gained this call path.\n\nThe problem call path is:\nMP_ioapic_info()\n mp_register_ioapic()\n io_apic_unique_id()\n io_apic_get_unique_id()\n get_physical_broadcast()\n modern_apic()\n lapic_get_version()\n apic_read(APIC_LVR)\n\nWhich turned out to be a problem because the local apic\nwas not mapped, at that point, unlike the similar point\nin the ACPI parsing code.\n\nThis problem is fixed by mapping the local apic when\nparsing the mptable as soon as we reasonably can.\n\nLooking at the number of places we setup the fixmap for\nthe local apic, I see some serious simplification opportunities.\nFor the moment except for not duplicating the setting up of the\nfixmap in init_apic_mappings, I have not acted on them.\n\nThe regression from 2.6.34 is tracked in bug\nhttps://bugzilla.kernel.org/show_bug.cgi?id\u003d16173\n\nCc: \u003cstable@kernel.org\u003e 2.6.35\nReported-by: David Hill \u003chilld@binarystorm.net\u003e\nReported-by: Tvrtko Ursulin \u003ctvrtko.ursulin@sophos.com\u003e\nTested-by: Tvrtko Ursulin \u003ctvrtko.ursulin@sophos.com\u003e\nSigned-off-by: Eric W.
