we switch\n over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO\n queue with priorities. This lets us be able to handle more events,\n have lower latency, and better scalability. Good stuff.\n\n The other is PVH by Mukesh Rathor. In short, PV is a mode where the\n kernel lets the hypervisor program page-tables, segments, etc. With\n EPT/NPT capabilities in current processors, the overhead of doing this\n in an HVM (Hardware Virtual Machine) container is much lower than the\n hypervisor doing it for us.\n\n In short we let a PV guest run without doing page-table, segment,\n syscall, etc updates through the hypervisor - instead it is all done\n within the guest container. It is a \"hybrid\" PV - hence the \u0027PVH\u0027\n name - a PV guest within an HVM container.\n\n The major benefits are less code to deal with - for example we only\n use one function from the the pv_mmu_ops (which has 39 function\n calls); faster performance for syscall (no context switches into the\n hypervisor); less traps on various operations; etc.\n\n It is still being baked - the ABI is not yet set in stone. But it is\n pretty awesome and we are excited about it.\n\n Lastly, there are some changes to ARM code - you should get a simple\n conflict which has been resolved in #linux-next.\n\n In short, this pull has awesome features.\n\n Features:\n - FIFO event channels. Key advantages: support for over 100,000\n events (2^17), 16 different event priorities, improved fairness in\n event latency through the use of FIFOs.\n - Xen PVH support. \"It’s a fully PV kernel mode, running with\n paravirtualized disk and network, paravirtualized interrupts and\n timers, no emulated devices of any kind (and thus no qemu), no BIOS\n or legacy boot — but instead of requiring PV MMU, it uses the HVM\n hardware extensions to virtualize the pagetables, as well as system\n calls and other privileged operations.\" (from \"The\n Paravirtualization Spectrum, Part 2: From poles to a spectrum\")\n\n Bug-fixes:\n - Fixes in balloon driver (refactor and make it work under ARM)\n - Allow xenfb to be used in HVM guests.\n - Allow xen_platform_pci\u003d0 to work properly.\n - Refactors in event channels\"\n\n* tag \u0027stable/for-linus-3.14-rc0-tag\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: (52 commits)\n xen/pvh: Set X86_CR0_WP and others in CR0 (v2)\n MAINTAINERS: add git repository for Xen\n xen/pvh: Use \u0027depend\u0027 instead of \u0027select\u0027.\n xen: delete new instances of __cpuinit usage\n xen/fb: allow xenfb initialization for hvm guests\n xen/evtchn_fifo: fix error return code in evtchn_fifo_setup()\n xen-platform: fix error return code in platform_pci_init()\n xen/pvh: remove duplicated include from enlighten.c\n xen/pvh: Fix compile issues with xen_pvh_domain()\n xen: Use dev_is_pci() to check whether it is pci device\n xen/grant-table: Force to use v1 of grants.\n xen/pvh: Support ParaVirtualized Hardware extensions (v3).\n xen/pvh: Piggyback on PVHVM XenBus.\n xen/pvh: Piggyback on PVHVM for grant driver (v4)\n xen/grant: Implement an grant frame array struct (v3).\n xen/grant-table: Refactor gnttab_init\n xen/grants: Remove gnttab_max_grant_frames dependency on gnttab_init.\n xen/pvh: Piggyback on PVHVM for event channels (v2)\n xen/pvh: Update E820 to work with PVH (v2)\n xen/pvh: Secondary VCPU bringup (non-bootup CPUs)\n ...\n" }, { "commit": "7ebd3faa9b5b42caf2d5aa1352a93dcfa0098011", "tree": "c45acf88b7976dcec117b6a3dbe31a7fe710ef33", "parents": [ "bb1281f2aae08e5ef23eb0692c8833e95579cdf2", "7650b6870930055426abb32cc47d164ccdea49db" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 22 21:40:43 2014 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 22 21:40:43 2014 -0800" }, "message": "Merge tag \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/virt/kvm/kvm\n\nPull KVM updates from Paolo Bonzini:\n \"First round of KVM updates for 3.14; PPC parts will come next week.\n\n Nothing major here, just bugfixes all over the place.

However, several bugs and opportunities\nfor simple improvements were found in the current implementation, mostly\nthrough extra tracepoints (which are however too ugly for now to be\nconsidered for sending).\n\nThe patches mostly deal with two mechanisms that reduce compaction\noverhead, which is caching the progress of migrate and free scanners,\nand marking pageblocks where isolation failed to be skipped during\nfurther scans.\n\nPatch 1 (from mgorman) adds tracepoints that allow calculate time spent in\n compaction and potentially debug scanner pfn values.\n\nPatch 2 encapsulates the some functionality for handling deferred compactions\n for better maintainability, without a functional change\n type is not determined without being actually needed.\n\nPatch 3 fixes a bug where cached scanner pfn\u0027s are sometimes reset only after\n they have been read to initialize a compaction run.\n\nPatch 4 fixes a bug where scanners meeting is sometimes not properly detected\n and can lead to multiple compaction attempts quitting early without\n doing any work.\n\nPatch 5 improves the chances of sync compaction to process pageblocks that\n async compaction has skipped due to being !MIGRATE_MOVABLE.\n\nPatch 6 improves the chances of sync direct compaction to actually do anything\n when called after async compaction fails during allocation slowpath.\n\nThe impact of patches were validated using mmtests\u0027s stress-highalloc\nbenchmark with mmtests\u0027s stress-highalloc benchmark on a x86_64 machine\nwith 4GB memory.\n\nDue to instability of the results (mostly related to the bugs fixed by\npatches 2 and 3), 10 iterations were performed, taking min,mean,max\nvalues for success rates and mean values for time and vmstat-based\nmetrics.\n\nFirst, the default GFP_HIGHUSER_MOVABLE allocations were tested with the\npatches stacked on top of v3.13-rc2. Patch 2 is OK to serve as baseline\ndue to no functional changes in 1 and 2.

I used to get stable\n values around 85% with vanilla 3.11. The lower min and mean values came\n with 3.12. This was bisected to commit 81c0a2bb (\"mm: page_alloc: fair\n zone allocator policy\") As explained in comment for patch 3, I don\u0027t\n think the commit is wrong, but that it makes the effect of compaction\n bugs worse. From patch 3 onwards, the results are OK and match the 3.11\n results.\n\n- Patch 4 also clearly helps phases 1 and 2, and exceeds any results\n I\u0027ve seen with 3.11 (I didn\u0027t measure it that thoroughly then, but it\n was never above 40%).\n\n- Compaction cost and number of scanned pages is higher, especially due\n to patch 4. However, keep in mind that patches 3 and 4 fix existing\n bugs in the current design of compaction overhead mitigation, they do\n not change it. If overhead is found unacceptable, then it should be\n decreased differently (and consistently, not due to random conditions)\n than the current implementation does. In contrast, patches 5 and 6\n (which are not strictly bug fixes) do not increase the overhead (but\n also not success rates). This might be a limitation of the\n stress-highalloc benchmark as it\u0027s quite uniform.\n\nAnother set of results is when configuring stress-highalloc t allocate\nwith similar flags as THP uses:\n (GFP_HIGHUSER_MOVABLE|__GFP_NOMEMALLOC|__GFP_NORETRY|__GFP_NO_KSWAPD)\n\nstress-highalloc\n 3.13-rc2 3.13-rc2 3.13-rc2 3.13-rc2 3.13-rc2\n 2-thp 3-thp 4-thp 5-thp 6-thp\nSuccess 1 Min 2.00 ( 0.00%) 7.00 (-250.00%) 18.00 (-800.00%) 19.00 (-850.00%) 26.00 (-1200.00%)\nSuccess 1 Mean 19.20 ( 0.00%) 17.80 ( 7.29%) 29.20 (-52.08%) 29.90 (-55.73%) 32.80 (-70.83%)\nSuccess 1 Max 27.00 ( 0.00%) 29.00 ( -7.41%) 35.00 (-29.63%) 36.00 (-33.33%) 37.00 (-37.04%)\nSuccess 2 Min 3.00 ( 0.00%) 8.00 (-166.67%) 21.00 (-600.00%) 21.00 (-600.00%) 32.00 (-966.67%)\nSuccess 2 Mean 19.30 ( 0.00%) 17.90 ( 7.25%) 32.20 (-66.84%) 32.60 (-68.91%) 35.70 (-84.97%)\nSuccess 2 Max 27.00 ( 0.00%) 30.00 (-11.11%) 36.00 (-33.33%) 37.00 (-37.04%) 39.00 (-44.44%)\nSuccess 3 Min 62.00 ( 0.00%) 62.00 ( 0.00%) 85.00 (-37.10%) 75.00 (-20.97%) 64.00 ( -3.23%)\nSuccess 3 Mean 66.30 ( 0.00%) 65.50 ( 1.21%) 85.60 (-29.11%) 83.40 (-25.79%) 83.50 (-25.94%)\nSuccess 3 Max 70.00 ( 0.00%) 69.00 ( 1.43%) 87.00 (-24.29%) 86.00 (-22.86%) 87.00 (-24.29%)\n\n 3.13-rc2 3.13-rc2 3.13-rc2 3.13-rc2 3.13-rc2\n 2-thp 3-thp 4-thp 5-thp 6-thp\nUser 6547.93 6475.85 6265.54 6289.46 6189.96\nSystem 1053.42 1047.28 1043.23 1042.73 1038.73\nElapsed 1835.43 1821.96 1908.67 1912.74 1956.38\n\n 3.13-rc2 3.13-rc2 3.13-rc2 3.13-rc2 3.13-rc2\n 2-thp 3-thp 4-thp 5-thp 6-thp\nMinor Faults 256805673 253106328 253222299 249830289 251184418\nMajor Faults 395 375 423 434 448\nSwap Ins 12 10 10 12 9\nSwap Outs 530 537 487 455 415\nDirect pages scanned 71859 86046 153244 152764 190713\nKswapd pages scanned 1900994 1870240 1898012 1892864 1880520\nKswapd pages reclaimed 1897814 1867428 1894939 1890125 1877924\nDirect pages reclaimed 71766 85908 153167 152643 190600\nKswapd efficiency 99% 99% 99% 99% 99%\nKswapd velocity 1029.000 1067.782 1000.091 991.049 951.218\nDirect efficiency 99% 99% 99% 99% 99%\nDirect velocity 38.897 49.127 80.747 79.983 96.468\nPercentage direct scans 3% 4% 7% 7% 9%\nZone normal velocity 351.377 372.494 348.910 341.689 335.310\nZone dma32 velocity 716.520 744.414 731.928 729.343 712.377\nZone dma velocity 0.000 0.000 0.000 0.000 0.000\nPage writes by reclaim 669.300 604.000 545.700 538.900 429.900\nPage writes file 138 66 58 83 14\nPage writes anon 530 537 487 455 415\nPage reclaim immediate 806 655 772 548 517\nSector Reads 2711956 2703239 2811602 2818248 2839459\nSector Writes 12163238 12018662 12038248 11954736 11994892\nPage rescued immediate 0 0 0 0 0\nSlabs scanned 1385088 1388364 1507968 1513292 1558656\nDirect inode steals 1739 2564 4622 5496 6007\nKswapd inode steals 47461 46406 47804 48013 48466\nKswapd skipped wait 0 0 0 0 0\nTHP fault alloc 110 82 84 69 70\nTHP collapse alloc 445 482 467 462 539\nTHP splits 6 5 4 5 3\nTHP fault fallback 3 0 0 0 0\nTHP collapse fail 15 14 14 14 13\nCompaction stalls 659 685 1033 1073 1111\nCompaction success 222 225 410 427 456\nCompaction failures 436 460 622 646 655\nPage migrate success 446594 439978 1085640 1095062 1131716\nPage migrate failure 0 0 0 0 0\nCompaction pages isolated 1029475 1013490 2453074 2482698 2565400\nCompaction migrate scanned 9955461 11344259 24375202 27978356 30494204\nCompaction free scanned 27715272 28544654 80150615 82898631 85756132\nCompaction cost 552 555 1344 1379 1436\nNUMA PTE updates 0 0 0 0 0\nNUMA hint faults 0 0 0 0 0\nNUMA hint local faults 0 0 0 0 0\nNUMA hint local percent 100 100 100 100 100\nNUMA pages migrated 0 0 0 0 0\nAutoNUMA cost 0 0 0 0 0\n\nThere are some differences from the previous results for THP-like allocations:\n\n- Here, the bad result for unpatched kernel in phase 3 is much more\n consistent to be between 65-70% and not related to the \"regression\" in\n 3.12. Still there is the improvement from patch 4 onwards, which brings\n it on par with simple GFP_HIGHUSER_MOVABLE allocations.\n\n- Compaction costs have increased, but nowhere near as much as the\n non-THP case. Again, the patches should be worth the gained\n determininsm.\n\n- Patches 5 and 6 somewhat increase the number of migrate-scanned pages.\n This is most likely due to __GFP_NO_KSWAPD flag, which means the cached\n pfn\u0027s and pageblock skip bits are not reset by kswapd that often (at\n least in phase 3 where no concurrent activity would wake up kswapd) and\n the patches thus help the sync-after-async compaction. It doesn\u0027t\n however show that the sync compaction would help so much with success\n rates, which can be again seen as a limitation of the benchmark\n scenario.\n\nThis patch (of 6):\n\nAdd two tracepoints for compaction begin and end of a zone.

This is done so that we save memory when several notification\ngroups are interested in the event. However the need for event\nstructure shared between inotify \u0026 fanotify bloats the event structure\nso the result is often higher memory consumption.\n\nAnother problem is that fsnotify framework keeps path references with\noutstanding events so that fanotify can return open file descriptors\nwith its events. This has the undesirable effect that filesystem cannot\nbe unmounted while there are outstanding events - a regression for\ninotify compared to a situation before it was converted to fsnotify\nframework. For fanotify this problem is hard to avoid and users of\nfanotify should kind of expect this behavior when they ask for file\ndescriptors from notified files.\n\nThis patch changes fsnotify and its users to create separate event\nstructure for each group. This allows for much simpler code (~400 lines\nremoved by this patch) and also smaller event structures. For example\non 64-bit system original struct fsnotify_event consumes 120 bytes, plus\nadditional space for file name, additional 24 bytes for second and each\nsubsequent group linking the event, and additional 32 bytes for each\ninotify group for private data. After the conversion inotify event\nconsumes 48 bytes plus space for file name which is considerably less\nmemory unless file names are long and there are several groups\ninterested in the events (both of which are uncommon). Fanotify event\nfits in 56 bytes after the conversion (fanotify doesn\u0027t care about file\nnames so its events don\u0027t have to have it allocated). A win unless\nthere are four or more fanotify groups interested in the event.\n\nThe conversion also solves the problem with unmount when only inotify is\nused as we don\u0027t have to grab path references for inotify events.\n\n[hughd@google.com: fanotify: fix corruption preventing startup]\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Eric Paris \u003ceparis@parisplace.org\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0abdd7a81b7e3fd781d7fabcca49501852bba17e", "tree": "20ab3aa4b476ceaf6d3a824c842cd581445ded8b", "parents": [ "03d11a0e458d7008192585124e4c3313c2829046" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Tue Jan 21 15:48:12 2014 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 21 16:19:41 2014 -0800" }, "message": "dma-debug: introduce debug_dma_assert_idle()\n\nRecord actively mapped pages and provide an api for asserting a given\npage is dma inactive before execution proceeds.

The changes to other subsystems (notably a slew of ARM\n machines as I am doing away with their custom APIs) have all been\n ACKed to the extent possible.\n\n Major changes this time:\n\n - Some core improvements and cleanups to the new GPIO descriptor API.\n This seems to be working now so we can start the exodus to this\n API, moving gradually away from the global GPIO numberspace.\n\n - Incremental improvements to the ACPI GPIO core, and move the few\n GPIO ACPI clients we have to the GPIO descriptor API right *now*\n before we go any further. We actually managed to contain this\n *before* we started to litter the kernel with yet another hackish\n global numberspace for the ACPI GPIOs, which is a big win.\n\n - The RFkill GPIO driver and all platforms using it have been\n migrated to use the GPIO descriptors rather than fixed number\n assignments. Tegra machine has been migrated as part of this.\n\n - New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x. Those\n should be really good examples of how I expect a nice GPIO driver\n to look these days.\n\n - Do away with custom GPIO implementations on a major part of the ARM\n machines: ks8695, lpc32xx, mv78xx0. Make a first step towards the\n same in the horribly convoluted Samsung S3C include forest. We\n expect to continue to clean this up as we move forward.\n\n - Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and\n lynxpoint.\n\n This makes the GPIOlib core aware that a certain GPIO line is used\n for IRQs and can then enforce some semantics such as disallowing a\n GPIO line marked as in use for IRQ to be switched to output mode.\n\n - Drop all use of irq_set_chip_and_handler_name(). The name provided\n in these cases were just unhelpful tags like \"mux\" or \"demux\".\n\n - Extend the MCP23s08 driver to handle interrupts.\n\n - Minor incremental improvements for rcar, lynxpoint, em 74x164 and\n msm drivers.\n\n - Some non-urgent bug fixes here and there, duplicate #includes and\n that usual kind of cleanups\"\n\nFix up broken Kconfig file manually to make this all compile.\n\n* tag \u0027gpio-v3.14-1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (71 commits)\n gpio: mcp23s08: fix casting caused build warning\n gpio: mcp23s08: depend on OF_GPIO\n gpio: mcp23s08: Add irq functionality for i2c chips\n ARM: S5P[v210|c100|64x0]: Fix build error\n gpio: pxa: clamp gpio get value to [0,1]\n ARM: s3c24xx: explicit dependency on \u003cplat/gpio-cfg.h\u003e\n ARM: S3C[24|64]xx: move includes back under \u003cmach/\u003e scope\n Documentation / ACPI: update to GPIO descriptor API\n gpio / ACPI: get rid of acpi_gpio.h\n gpio / ACPI: register to ACPI events automatically\n mmc: sdhci-acpi: convert to use GPIO descriptor API\n ARM: s3c24xx: fix build error\n gpio: f7188x: set can_sleep attribute\n gpio: samsung: Update documentation\n gpio: samsung: Remove hardware.h inclusion\n gpio: xtensa: depend on HAVE_XTENSA_GPIO32\n gpio: clps711x: Enable driver compilation with COMPILE_TEST\n gpio: clps711x: Use of_match_ptr()\n net: rfkill: gpio: convert to descriptor-based GPIO interface\n leds: s3c24xx: Fix build failure\n ...\n" }, { "commit": "02d0a752460ea5dab34ce36c9ddc9c682e846a0d", "tree": "094908b333a993b2160ee220f794a908a5e355b6", "parents": [ "fb2e2c85375a0380d6818f153ffa2ae9ebbd055f", "5f1b11555ef21fb3a8a9d21a2e5914e2bc1b9d9b" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 21 09:39:37 2014 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 21 09:39:37 2014 -0800" }, "message": "Merge branch \u0027i2c/for-next\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux\n\nPull i2c updates from Wolfram Sang:\n \"For 3.14, the I2C subsystem has the following to offer:\n\n - new drivers for Renesas RIIC and RobotFuzz OSIF\n - driver cleanups \u0026 improvements \u0026 bugfixes\n\n Pretty standard stuff this time, I\u0027d say.
