As part of this,\npage_table_shareable() checks a pair of vma-\u003evm_flags and they must match\nif they are to be shared. All VMA flags are taken into account, including\nVM_LOCKED.\n\nThe problem is that VM_LOCKED is cleared on fork(). When a process with a\nshared memory segment forks() to exec() a helper, there will be shared\nVMAs with different flags. The impact is that the shared segment is\nsometimes considered shareable and other times not, depending on what\nprocess is checking.\n\nWhat happens is that the segment page tables are being shared but the\ncount is inaccurate depending on the ordering of events. As the page\ntables are freed with put_page(), bad pmd\u0027s are found when some of the\nchildren exit. The hugepage counters also get corrupted and the Total and\nFree count will no longer match even when all the hugepage-backed regions\nare freed. This requires a reboot of the machine to \"fix\".\n\nThis patch addresses the problem by comparing all flags except VM_LOCKED\nwhen deciding if pagetables should be shared or not for

own (in fact, ours is itself a dup on an old variant of the vmalloc\n one), unfortunately, the approach is terminally busted since\n dma_alloc_coherent() can be called at interrupt time or in atomic contexts\n and there\u0027s little chances we\u0027ll make the code in mm/vmalloc.c cope with\\ that :-(\n\n Until we can get the generic code to forbid that idiocy and fix all\n drivers abusing it, we pretty much have no choice but revert to\n our custom virtual space allocator.\n\n There\u0027s also a problem with SMP safety since freeing such mapping\n would require an IPI which cannot be done at interrupt time.\n\n However, right now, I don\u0027t think we support any platform that is\n both SMP and has non-coherent DMA (don\u0027t laugh, I know such things\n do exist !) so we can sort

The\nmain reason for doing is this is to allow us to transfer a\nperf_counter_context from one task to another when we do lazy PMU\nswitching in a later patch.\n\nThis has a few side-benefits: the task_struct becomes a little smaller,\nwe save some memory because only tasks that have perf_counters attached\nget a perf_counter_context allocated for them, and we can remove the\ninclusion of \u003clinux/perf_counter.h\u003e in sched.h, meaning that we don\u0027t\nend up recompiling nearly everything whenever perf_counter.h changes.\n\nThe perf_counter_context structures are reference-counted and freed\nwhen the last reference is dropped. A context can have references\nfrom its task and the counters on its task. Counters can outlive the\ntask so it is possible that a context will be freed well after its\ntask has exited.\n\nContexts are allocated on fork if the parent had a context, or\notherwise the first time that a per-task counter is created on a task.\nIn the latter case, we set the context pointer in the task struct\nlocklessly using an atomic compare-and-exchange operation in case we\nraced with some other task in creating a context for the subject task.\n\nThis also removes the task pointer from the perf_counter struct. The\ntask pointer was not used anywhere and would make it harder to move a\ncontext from one task to another. Anything that needed to know which\ntask a counter was attached to was already using counter-\u003ectx-\u003etask.\n\nThe __perf_counter_init_context function moves up in perf_counter.c\nso that it can be called from find_get_context, and now initializes\nthe refcount, but is otherwise unchanged.\n\nWe were potentially calling list_del_counter twice: once from\n__perf_counter_exit_task when the task exits and once from\n__perf_counter_remove_from_context when the counter\u0027s fd gets closed.\nThis adds a check in list_del_counter so it doesn\u0027t do anything if\nthe counter has already been removed from the lists.\n\nSince perf_counter_task_sched_in doesn\u0027t do anything if the task doesn\u0027t\nhave a context, and leaves cpuctx-\u003etask_ctx \u003d NULL, this adds code to\n__perf_install_in_context to set cpuctx-\u003etask_ctx if necessary, i.e. in\nthe case where the current task adds the first counter to itself and\nthus creates a context for itself.\n\nThis also adds similar code to __perf_counter_enable to handle a\nsimilar situation which can arise when the counters have been disabled\nusing prctl; that also leaves cpuctx-\u003etask_ctx \u003d NULL.\n\n[ Impact: refactor counter context management to prepare for new feature ]\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Corey Ashford \u003ccjashfor@linux.vnet.ibm.com\u003e\nCc: Marcelo Tosatti \u003cmtosatti@redhat.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nLKML-Reference: \u003c18966.10075.781053.231153@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "88dff4936c0a5fa53080cca68dc963a8a2a674b0", "tree": "699318cdd98daf4773cab5a27d432f11078faace", "parents": [ "279e677faa775ad16e75c32e1bf4a37f8158bc61" ], "author": { "name": "Zhang Rui", "email": "rui.zhang@intel.com", "time": "Fri May 22 11:35:50 2009 +0800" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri May 22 09:11:30 2009 +0200" }, "message": "x86: DMI match for the Sony VGN-Z540N as it needs BIOS reboot\n\nx86: DMI match for the Sony VGN-Z540N as it needs BIOS reboot,\nsee:\n\n http://bugzilla.kernel.org/show_bug.cgi?id\u003d12901\n\n[ Impact: fix hung reboot on certain systems ]\n\nSigned-off-by: Zhang Rui \u003crui.zhang@intel.com\u003e\nCc: Len Brown \u003clenb@kernel.org\u003e\nLKML-Reference: \u003c1242963350.32574.53.camel@rzhang-dt\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "6eb0ac03899a1363ba176abe0830a9e6698c0503", "tree": "11d36f24f5fba90d051b7be3439d85e41e731044", "parents": [ "5805977e63a36ad56594a623f3bd2bebcb7db233" ], "author": { "name": "Michael Ellerman", "email": "michael@ellerman.id.au", "time": "Thu May 21 19:10:23 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri May 22 16:01:11 2009 +1000" }, "message": "powerpc/maple: Add a quirk to disable MSI for IPR on Bimini\n\nSomething in the HW or FW setup is busted and MSIs aren\u0027t working with\nIPR on Bimini, so until we figure out exaxtly what\u0027s up, we quirk them\nout\n\nSigned-off-by: Michael Ellerman \u003cmichael@ellerman.id.au\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "37869fa2da1a952ed736858f8b9e45c0b9131ae9", "tree": "eb7ae599e4fd98008651070cb2847a1a7c896a19", "parents": [ "5805977e63a36ad56594a623f3bd2bebcb7db233" ], "author": { "name": "Magnus Damm", "email": "damm@igel.co.jp", "time": "Wed May 20 14:30:06 2009 +0000" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Fri May 22 13:19:11 2009 +0900" }, "message": "sh: ap325 camera without i2c driver fix\n\nThis patch fixes the ap325rxa ncm03j camera code to handle\nthe case where no i2c driver is present.

able to tell if a given PFN has valid memmap\nassociated with it or not. In FLATMEM, it is expected that holes always\nhave valid memmap as long as there is valid PFNs either side of the hole.\nIn SPARSEMEM, it is assumed that a valid section has a memmap for the\nentire section.\n\nHowever, ARM and maybe other embedded architectures in the future free\nmemmap backing holes to save memory on the assumption the memmap is never\nused. The page_zone linkages are then broken even though pfn_valid()\nreturns true. A walker of the full memmap must then do this additional\ncheck to ensure the memmap they are looking at is sane by making sure the\nzone and PFN linkages are still valid. This is expensive, but walkers of\nthe full memmap are extremely rare.\n\nThis was caught before for FLATMEM and hacked around but it hits again for\nSPARSEMEM because the page_zone linkages can look ok where the PFN linkages\nare totally screwed. This looks like a hatchet job but the reality is that\nany clean solution would end up consumning all the memory saved by punching\nthese unexpected holes in the memmap. For example, we tried marking the\nmemmap within the section invalid but the section size exceeds the size of\nthe hole in most cases so pfn_valid() starts returning false where valid\nmemmap exists. Shrinking the size of the section would increase memory\nconsumption offsetting the gains.\n\nThis patch identifies when an architecture is punching unexpected holes\nin the memmap that the memory model cannot automatically detect and sets\nARCH_HAS_HOLES_MEMORYMODEL. At the moment, this is restricted to EP93xx\nwhich is the model sub-architecture this has been reported on but may expand\nlater. When set, walkers of the full memmap must call memmap_valid_within()\nfor each PFN and passing in what it expects the page and zone to be for\nthat PFN. If it finds the linkages to be broken, it assumes the memmap is\ninvalid for that PFN.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "b68f1d2e7aa21029d73c7d453a8046e95d351740", "tree": "2fa9e94f340e84e037bce4d3e3ffd5a6f88a9039", "parents": [ "c0daaf3f1f672defa3a45ca449b76d0e86c55892" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun May 17 19:37:25 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon May 18 09:37:09 2009 +0200" }, "message": "perf_counter, x86: speed up the scheduling fast-path\n\nWe have to set up the LVT entry only at counter init time, not at\nevery switch-in time.\n\nThere\u0027s friction between NMI and non-NMI use here -

The working theory is\nthat the CPU\u0027s pipeline is getting upset about the\ncall-\u003ecall-\u003elocked-op-\u003ereturn-\u003ereturn, and seems to be failing to\nspeculate (though I haven\u0027t seen anything definitive about the precise\nreasons). This doesn\u0027t entirely make sense, because the performance\nhit is also visible on unlock and other operations which don\u0027t involve\nlocked instructions. But spinlock operations clearly swamp all the\nother pvops operations, even though I can\u0027t imagine that they\u0027re\nnearly as common (there\u0027s only a .05% increase in instructions\nexecuted).\n\nIf I disable just the pv-spinlock calls, my tests show that pvops is\nidentical to non-pvops performance on native (my measurements show that\nit is actually about .1% faster, but Xiaohui shows a .05% slowdown).\n\nSummary of results, averaging 10 runs of the \"mmperf\" test, using a\nno-pvops build as baseline:\n\n\t\tnopv\t\tPv-nospin\tPv-spin\nCPU cycles\t100.00%\t\t99.89%\t\t102.18%\ninstructions\t100.00%\t\t100.10%\t\t100.15%\nCPI\t\t100.00%\t\t99.79%\t\t102.03%\ncache ref\t100.00%\t\t100.84%\t\t100.28%\ncache miss\t100.00%\t\t90.47%\t\t88.56%\ncache miss rate\t100.00%\t\t89.72%\t\t88.31%\nbranches\t100.00%\t\t99.93%\t\t100.04%\nbranch miss\t100.00%\t\t103.66%\t\t107.72%\nbranch miss rt\t100.00%\t\t103.73%\t\t107.67%\nwallclock\t100.00%\t\t99.90%\t\t102.20%\n\nThe clear effect here is that the 2% increase in CPI is\ndirectly reflected in the final wallclock time.\n\n(The other interesting effect is that the more ops are\nout of line calls via pvops, the lower the cache access\nand miss rates. Not too surprising, but it suggests that\nthe non-pvops kernel is over-inlined. On the flipside,\nthe branch misses go up correspondingly...)\n\nSo, what\u0027s the fix?\n\nParavirt patching turns all the pvops calls into direct calls, so\n_spin_lock etc do end up having direct calls. For example, the compiler\ngenerated code for paravirtualized _spin_lock is:\n\n\u003c_spin_lock+0\u003e:\t\tmov %gs:0xb4c8,%rax\n\u003c_spin_lock+9\u003e:\t\tincl 0xffffffffffffe044(%rax)\n\u003c_spin_lock+15\u003e:\tcallq *0xffffffff805a5b30\n\u003c_spin_lock+22\u003e:\tretq\n\nThe indirect call will get patched to:\n\u003c_spin_lock+0\u003e:\t\tmov %gs:0xb4c8,%rax\n\u003c_spin_lock+9\u003e:\t\tincl 0xffffffffffffe044(%rax)\n\u003c_spin_lock+15\u003e:\tcallq \u003c__ticket_spin_lock\u003e\n\u003c_spin_lock+20\u003e:\tnop; nop\t\t/* or whatever 2-byte nop */\n\u003c_spin_lock+22\u003e:\tretq\n\nOne possibility is to inline _spin_lock, etc, when building an\noptimised kernel (ie, when there\u0027s no spinlock/preempt\ninstrumentation/debugging enabled). That will remove the outer\ncall/return pair, returning the instruction stream to a single\ncall/return, which will presumably execute the same as the non-pvops\ncase. The downsides arel 1) it will replicate the\npreempt_disable/enable code at eack lock/unlock callsite; this code is\nfairly small, but not nothing; and 2) the spinlock definitions are\nalready a very heavily tangled mass of #ifdefs and other preprocessor\nmagic, and making any changes will be non-trivial.\n\nThe other obvious answer is to disable pv-spinlocks. Making them a\nseparate config option is fairly easy, and it would be trivial to\nenable them only when Xen is enabled (as the only non-default user).\nBut it doesn\u0027t really address the common case of a distro build which\nis going to have Xen support enabled, and leaves the open question of\nwhether the native performance cost of pv-spinlocks is worth the\nperformance improvement on a loaded Xen system (10% saving of overall\nsystem CPU when guests block rather than spin). Still it is a\nreasonable short-term workaround.\n\n[ Impact: fix pvops performance regression when running native ]\n\nAnalysed-by: \"Xin Xiaohui\" \u003cxiaohui.xin@intel.com\u003e\nAnalysed-by: \"Li Xin\" \u003cxin.li@intel.com\u003e\nAnalysed-by: \"Nakajima Jun\" \u003cjun.nakajima@intel.com\u003e\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nAcked-by: H.

overflow events\n\nThis uses values from the MMCRA, SIAR and SDAR registers on\npowerpc to supply more precise information for overflow events,\nincluding a data address when PERF_RECORD_ADDR is specified.\n\nSince POWER6 uses different bit positions in MMCRA from earlier\nprocessors, this converts the struct power_pmu limited_pmc5_6\nfield, which only had 0/1 values, into a flags field and\ndefines bit values for its previous use (PPMU_LIMITED_PMC5_6)\nand a new flag (PPMU_ALT_SIPR) to indicate that the processor\nuses the POWER6 bit positions rather than the earlier\npositions. It also adds definitions in reg.h for the new and\nold positions of the bit that indicates that the SIAR and SDAR\nvalues come from the same instruction.\n\nFor the data address, the SDAR value is supplied if we are not\ndoing instruction sampling. In that case there is no guarantee\nthat the address given in the PERF_RECORD_ADDR subrecord will\ncorrespond to the instruction whose address is given in the\nPERF_RECORD_IP subrecord.\n\nIf instruction sampling is enabled (e.g. because this counter\nis counting a marked instruction event), then we only supply\nthe SDAR value for the PERF_RECORD_ADDR subrecord if it\ncorresponds to the instruction whose address is in the\nPERF_RECORD_IP subrecord. Otherwise we supply 0.\n\n[ Impact: support more PMU hardware features on PowerPC ]\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Corey Ashford \u003ccjashfor@linux.vnet.ibm.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nLKML-Reference: \u003c18955.37028.48861.555309@drongo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" } ], "next": "ef923214a4816c289e4af2d67a9ebb1a31e4ac61" }
