The\n current MCE poller uses a static interval which does not care whether it\n has or has not found MCEs recently.\n\nDescription:\n This patch makes the MCE poller adjust the polling interval dynamically.\n If we find an MCE, poll 2x faster (down to 10 ms). When we stop finding\n MCEs, poll 2x slower (up to check_interval seconds). The check_interval\n tunable becomes the max polling interval. The \"Machine check events\n logged\" printk() is rate limited to the check_interval, which should be\n identical behavior to the old functionality.\n\nResult:\n If you start to take a lot of correctable errors (not exceptions), you\n log them faster and more accurately (less chance of overflowing the MCA\n registers). If you don\u0027t take a lot of errors, you will see no change.\n\nAlternatives:\n I considered simply reducing the polling interval to 10 ms immediately\n and keeping it there as long as we continue to find errors. This felt a\n bit heavy handed, but does perform significantly better for the default\n check_interval of 5 minutes (we\u0027re using a few seconds when testing for\n DRAM errors). I could be convinced to go with this, if anyone felt it\n was not too aggressive.\n\nTesting:\n I used an error-injecting DIMM to create lots of correctable DRAM errors\n and verified that the polling interval accelerates. The printk() only\n happens once per check_interval seconds.\n\nPatch:\n This patch is against 2.6.21-rc7.\n\nSigned-Off-By: Tim Hockin \u003cthockin@google.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n" }, { "commit": "f82af20e1a028e16b9bb11da081fa1148d40fa6a", "tree": "90bff2de9c6f005ef0733031612cff38fc3576ca", "parents": [ "889f21ce272e38db19c8114a7e0a5793d4590077" ], "author": { "name": "Gerd Hoffmann", "email": "kraxel@suse.de", "time": "Wed May 02 19:27:19 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:19 2007 +0200" }, "message": "[PATCH] x86-64: ignore vgacon if hardware not present\n\nAvoid trying to set up vgacon if there\u0027s no vga hardware present.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Alan \u003calan@lxorguk.ukuu.org.uk\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "889f21ce272e38db19c8114a7e0a5793d4590077", "tree": "a29dd9164a44bbaa26a454922a78fd7dda638540", "parents": [ "425001fea782dd072cfec5694b93778eb59a1fd3" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Wed May 02 19:27:19 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:19 2007 +0200" }, "message": "[PATCH] i386: fix wrong comment for syscall stack layout\n\n`ret_from_sys_call\u0027 label no longer exist and `syscall_exit\u0027 label was\nintroduced instead.\n\nSigned-off-by: Satoru Takeuchi \u003ctakeuchi_satoru@jp.fujitsu.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n" }, { "commit": "425001fea782dd072cfec5694b93778eb59a1fd3", "tree": "5a46a75ee666908c8c8ef533c8a9b87f533e7dde", "parents": [ "f26d6a2bbcf381230df771123578380584004631" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Wed May 02 19:27:19 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:19 2007 +0200" }, "message": "[PATCH] x86-64: unexport cpu_llc_id\n\nWARNING: arch/x86_64/kernel/built-in.o - Section mismatch: reference to .init.data:cpu_llc_id from __ksymtab between \u0027__ksymtab_cpu_llc_id\u0027 (at offset 0x4a0) and \u0027__ksymtab_smp_num_siblings\u0027\n\nIt is strange to export a __cpuinitdata symbols to modules, and no module\nappears to use it anyway.\n\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n" }, { "commit": "f26d6a2bbcf381230df771123578380584004631", "tree": "a3a0f96059c27262db6655a605bfed77949471cf", "parents": [ "9e5e3162b2d5e4466187ecd63c9eec2de33cb7bc" ], "author": { "name": "Eric W.

Kdump uses an IPI\nto stop the other CPUs in the event of a crash, but when any of the\nother CPUs are locked-up inside the NMI handler the CPU that sends the\nIPI will end up looping forever in the ICR check, effectively\nhard-locking the whole system.\n\nQuoting from Intel\u0027s \"MultiProcessor Specification\" (Version 1.4), B-3:\n\n\"A local APIC unit indicates successful dispatch of an IPI by\nresetting the Delivery Status bit in the Interrupt Command\nRegister (ICR).

Fix `make headers_check\u0027.\n\nAMD and Intel x86 CPU manuals state that it is the responsibility of\nsystem software to initialize and maintain MTRR consistency across\nall processors in Multi-Processing Environments.\n\nQuote from page 188 of the AMD64 System Programming manual (Volume 2):\n\n7.6.5 MTRRs in Multi-Processing Environments\n\n\"In multi-processing environments, the MTRRs located in all processors must\ncharacterize memory in the same way. Generally, this means that identical\nvalues are written to the MTRRs used by the processors.\" (short omission here)\n\"Failure to do so may result in coherency violations or loss of atomicity.\nProcessor implementations do not check the MTRR settings in other processors\nto ensure consistency. It is the responsibility of system software to\ninitialize and maintain MTRR consistency across all processors.\"\n\nCurrent Linux MTRR code already implements the above in the case that the\nBIOS does not properly initialize MTRRs on the secondary processors,\nbut the case where the fixed-range MTRRs of the boot processor are changed\nafter Linux started to boot, before the initialsation of a secondary\nprocessor, is not handled yet.\n\nIn this case, secondary processors are currently initialized by Linux\nwith MTRRs which the boot processor had very early, when mtrr_bp_init()\ndid run, but not with the MTRRs which the boot processor uses at the\ntime when that secondary processors is actually booted,\ncausing differing MTRR contents on the secondary processors.\n\nSuch situation happens on Acer Ferrari 1000 and 5000 notebooks where the\nBIOS enables and sets AMD-specific IORR bits in the fixed-range MTRRs\nof the boot processor when it transitions the system into ACPI mode.\nThe SMI handler of the BIOS does this in SMM, entered while Linux ACPI\ncode runs acpi_enable().\n\nOther occasions where the SMI handler of the BIOS may change bits in\nthe MTRRs could occur as well. To initialize newly booted secodary\nprocessors with the fixed-range MTRRs which the boot processor uses\nat that time, this patch saves the fixed-range MTRRs of the boot\nprocessor before new secondary processors are started. When the\nsecondary processors run their Linux initialisation code, their\nfixed-range MTRRs will be updated with the saved fixed-range MTRRs.\n\nIf CONFIG_MTRR is not set, we define mtrr_save_state\nas an empty statement because there is nothing to do.\n\nPossible TODOs:\n\n*) CPU-hotplugging outside of SMP suspend/resume is not yet tested\n with this patch.\n\n*) If, even in this case, an AP never runs i386/do_boot_cpu or x86_64/cpu_up,\n then the calls to mtrr_save_state() could be replaced by calls to\n mtrr_save_fixed_ranges(NULL) and mtrr_save_state() would not be\n needed.\n\n That would need either verification of the CPU-hotplug code or\n at least a test on a \u003e2 CPU machine.\n\n*) The MTRRs of other running processors are not yet checked at this\n time but it might be interesting to syncronize the MTTRs of all\n processors before booting. That would be an incremental patch,\n but of rather low priority since there is no machine known so\n far which would require this.\n\nAK: moved prototypes on x86-64 around to fix warnings\n\nSigned-off-by: Bernhard Kaindl \u003cbk@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Dave Jones \u003cdavej@codemonkey.org.uk\u003e\n" }, { "commit": "2b3b4835c94226681c496de9446d456dcf42ed08", "tree": "a7f005ccb038107153059691dbabf048b560521d", "parents": [ "856f44ff4af6e57fdc39a8b2bec498c88438bd27" ], "author": { "name": "Bernhard Kaindl", "email": "bk@suse.de", "time": "Wed May 02 19:27:17 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:17 2007 +0200" }, "message": "[PATCH] x86: Adds mtrr_save_fixed_ranges() for use in two later patches.\n\nIn this current implementation which is used in other patches,\nmtrr_save_fixed_ranges() accepts a dummy void pointer because\nin the current implementation of one of these patches, this\nfunction may be called from smp_call_function_single() which\nrequires that this function takes a void pointer argument.\n\nThis function calls get_fixed_ranges(), passing mtrr_state.fixed_ranges\nwhich is the element of the static struct which stores our current\nbackup of the fixed-range MTRR values which all CPUs shall be\nusing.\n\nBecause mtrr_save_fixed_ranges calls get_fixed_ranges after\nkernel initialisation time, __init needs to be removed from\nthe declaration of get_fixed_ranges().\n\nIf CONFIG_MTRR is not set, we define mtrr_save_fixed_ranges\nas an empty statement because there is nothing to do.\n\nAK: Moved prototypes for x86-64 around to fix warnings\n\nSigned-off-by: Bernhard Kaindl \u003cbk@suse.de\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Dave Jones \u003cdavej@codemonkey.org.uk\u003e\n" }, { "commit": "856f44ff4af6e57fdc39a8b2bec498c88438bd27", "tree": "475ca01f27c3272ec9e3d15f3d8209ad4424c3bc", "parents": [ "03df4f6ee997589a84d5f9492c6419183724c710" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Wed May 02 19:27:17 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:17 2007 +0200" }, "message": "[PATCH] x86-64: Move mtrr prototypes from proto.h to mtrr.h\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n" }, { "commit": "03df4f6ee997589a84d5f9492c6419183724c710", "tree": "94b79a8b18bab6032ce8e241c7a56fe007cd587c", "parents": [ "21564fd2a3deb48200b595332f9ed4c9f311f2a7" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Wed May 02 19:27:17 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:17 2007 +0200" }, "message": "[PATCH] i386: Clean up ELF note generation\n\nThree cleanups:\n\n1: ELF notes are never mapped, so there\u0027s no need to have any access\nflags in their phdr.\n\n2: When generating them from asm, tell the assembler to use a SHT_NOTE\nsection type.

One is that vmalloc will update the\nkernel address space mappings, and those updates need to be propagated into\nall processes if the kernel mappings are not intrinsically shared. In the\nnon-PAE case, this is done by maintaining a pgd_list of all processes; this\nlist is used when all process pagetables must be updated. pgd_list is\nthreaded via otherwise unused entries in the page structure for the pgd, which\nmeans that the pgd must be page-sized for this to work.\n\nNormally the PAE pgd is only 4x64 byte entries large, but Xen requires the PAE\npgd to page aligned anyway, so this patch forces the pgd to be page\naligned+sized when the kernel pmd is unshared, to accomodate both these\nrequirements.\n\nAlso, since there may be several distinct kernel pmds (if the user/kernel\nsplit is below 3G), there\u0027s no point in allocating them from a slab cache;\nthey\u0027re just allocated with get_free_page and initialized appropriately.

When\nthe VM subsystem is initialized, it creates a proper pagetable which\nrespects the PAE mode, large pages, etc.\n\nWhen booting under a hypervisor, there are many possibilities for what\npaging environment the hypervisor establishes for the guest kernel, so\nthe constructon of the kernel\u0027s pagetable depends on the hypervisor.\n\nIn the case of Xen, the hypervisor boots the kernel with a fully\nconstructed pagetable, which is already using PAE if necessary. Also,\nXen requires particular care when constructing pagetables to make sure\nall pagetables are always mapped read-only.\n\nIn order to make this easier, kernel\u0027s initial pagetable construction\nhas been changed to only allocate and initialize a pagetable page if\nthere\u0027s no page already present in the pagetable. This allows the Xen\nparavirt backend to make a copy of the hypervisor-provided pagetable,\nallowing the kernel to establish any more mappings it needs while\nkeeping the existing ones.\n\nA slightly subtle point which is worth highlighting here is that Xen\nrequires all kernel mappings to share the same pte_t pages between all\npagetables, so that updating a kernel page\u0027s mapping in one pagetable\nis reflected in all other pagetables. This makes it possible to\nallocate a page and attach it to a pagetable without having to\nexplicitly enumerate that page\u0027s mapping in all pagetables.\n\nAnd:\n\n+From: \"Eric W.
