First one is Contiguous Memory\n Allocator (CMA) which makes it possible for device drivers to allocate\n big contiguous chunks of memory after the system has booted.\n\n The main difference from the similar frameworks is the fact that CMA\n allows to transparently reuse the memory region reserved for the big\n chunk allocation as a system memory, so no memory is wasted when no\n big chunk is allocated. Once the alloc request is issued, the\n framework migrates system pages to create space for the required big\n chunk of physically contiguous memory.\n\n For more information one can refer to nice LWN articles:\n\n - \u0027A reworked contiguous memory allocator\u0027:\n\t\thttp://lwn.net/Articles/447405/\n\n - \u0027CMA and ARM\u0027:\n\t\thttp://lwn.net/Articles/450286/\n\n - \u0027A deep dive into CMA\u0027:\n\t\thttp://lwn.net/Articles/486301/\n\n - and the following thread with the patches and links to all previous\n versions:\n\t\thttps://lkml.org/lkml/2012/4/3/204\n\n The main client for this new framework is ARM DMA-mapping subsystem.\n\n The second part provides a complete redesign in ARM DMA-mapping\n subsystem. The core implementation has been changed to use common\n struct dma_map_ops based infrastructure with the recent updates for\n new dma attributes merged in v3.4-rc2. This allows to use more than\n one implementation of dma-mapping calls and change/select them on the\n struct device basis. The first client of this new infractructure is\n dmabounce implementation which has been completely cut out of the\n core, common code.\n\n The last patch of this redesign update introduces a new, experimental\n implementation of dma-mapping calls on top of generic IOMMU framework.\n This lets ARM sub-platform to transparently use IOMMU for DMA-mapping\n calls if one provides required IOMMU hardware.\n\n For more information please refer to the following thread:\n\t\thttp://www.spinics.net/lists/arm-kernel/msg175729.html\n\n The last patch merges changes from both updates and provides a\n resolution for the conflicts which cannot be avoided when patches have\n been applied on the same files (mainly arch/arm/mm/dma-mapping.c).\"\n\nAcked by Andrew Morton \u003cakpm@linux-foundation.org\u003e:\n \"Yup, this one please.

The major reason for\nthat is that many people seem to be under the impression that this is\nalso for synchronization with outstanding asynchronous processsing.\nI\u0027m pretty massively opposed to this because:\n\n- It boils down reinventing a new rather general-purpose userspace\n synchronization interface. If we look at things like futexes, this\n is hard to get right.\n- Furthermore a lot of kernel code has to interact with this\n synchronization primitive. This smells a look like the dri1 hw_lock,\n a horror show I prefer not to reinvent.\n- Even more fun is that multiple different subsystems would interact\n here, so we have plenty of opportunities to create funny deadlock\n scenarios.\n\nI think synchronization is a wholesale different problem from data\nsharing and should be tackled as an orthogonal problem.\n\nNow we could demand that prepare/finish may only ensure cache\ncoherency (as Rob intended), but that runs up into the next problem:\nWe not only need mmap support to facilitate sw-only processing nodes\nin a pipeline (without jumping through hoops by importing the dma_buf\ninto some sw-access only importer), which allows for a nicer\nION-\u003edma-buf upgrade path for existing Android userspace. We also need\nmmap support for existing importing subsystems to support existing\nuserspace libraries. And a loot of these subsystems are expected to\nexport coherent userspace mappings.\n\nSo prepare/finish can only ever be optional and the exporter /needs/\nto support coherent mappings. Given that mmap access is always\nsomewhat fallback-y in nature I\u0027ve decided to drop this optimization,\ninstead of just making it optional. If we demonstrate a clear need for\nthis, supported by benchmark results, we can always add it in again\nlater as an optional extension.\n\nOther differences compared to Rob\u0027s RFC is the above mentioned support\nfor mapping a dma-buf through facilities provided by the importer.\nWhich results in mmap support no longer being optional.\n\nNote that this dma-buf mmap patch does _not_ support every possible\ninsanity an existing subsystem could pull of with mmap: Because it\ndoes not allow to intercept pagefaults and shoot down ptes importing\nsubsystems can\u0027t add some magic of their own at these points (e.g. to\nautomatically synchronize with outstanding rendering or set up some\nspecial resources). I\u0027ve done a cursory read through a few mmap\nimplementions of various subsytems and I\u0027m hopeful that we can avoid\nthis (and the complexity it\u0027d bring with it).\n\nAdditonally I\u0027ve extended the documentation a bit to explain the hows\nand whys of this mmap extension.\n\nIn case we ever want to add support for explicitly cache maneged\nuserspace mmap with a prepare/finish ioctl pair, we could specify that\nuserspace needs to mmap a different part of the dma_buf, e.g. the\nrange starting at dma_buf-\u003esize up to dma_buf-\u003esize*2.

Majority of\n changes are found, as usual, in HD-audio and ASoC.\n\n Some highlights of HD-audio changes:\n\n - All the long-standing static quirk codes for Realtek codec were\n finally removed by fixing and extending the Realtek auto-parser.\n\n - The mute-LED control is standardized over all HD-audio codec\n drivers using the extended vmaster hook.\n\n - The vmaster slave mixer elements are initialized to 0dB as default\n so that the user won\u0027t be annoyed by the silent output after\n updates, e.g. due to the additions of new elements.\n\n - Other many fix-ups for the misc HD-audio devices.\n\n In the ASoC side, this is a very active release, including a quite a\n few framework enhancements. Some highlights:\n\n - Support for widgets not associated with a CODEC, an important part\n of the dynamic PCM framework.\n\n - A library factoring out the common code shared by dmaengine based\n DMA drivers contributed by Lars-Peter Clausen. This will save a\n lot of code and make it much easier to deploy enhancements to\n dmaengine.\n\n - Support for binary controls, used for providing runtime\n configuration of algorithm coefficients.\n\n - A new DAPM widget type for regulator supplies allowing drivers for\n devices that can power down unused supplies while active to do\n without any per-driver code.\n\n - DAPM widgets for DAIs, initially giving a speed boost for playback\n startup and shutdown and also the basis for CODEC\u003c-\u003eCODEC DAI link\n support.\n\n - Support for specifying the number of significant bits on audio\n interfaces, useful for allowing applications to know how much\n effort to put into generating data for a larger sample format.\n\n - Conversion of the FSI driver used on some SH processors to\n DMAEngine.\n\n - Conversion of EP93xx drivers to DMAEngine.\n\n - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics\n WM2200.\n\n - Move audmux driver from arc/arm to sound/soc\n\n - McBSP move from arch/ to sound/ and updates\n\n Also, a few small updates and fixes for other drivers like au88x0,\n ymfpci, USB 6fire, USB usx2yaudio are included.\"\n\n* tag \u0027sound-3.4\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (446 commits)\n ASoC: wm8994: Provide VMID mode control and fix default sequence\n ASoC: wm8994: Add missing break in resume\n ASoC: wm_hubs: Don\u0027t actively manage LINEOUT_VMID_BUF\n ASoC: pxa-ssp: atomically set stream active masks\n ASoC: fsl: p1022ds: tell the WM8776 codec driver that it\u0027s the master\n ASoC: Samsung: Added to support mono recording\n ALSA: hda - Fix build with CONFIG_PM\u003dn\n ALSA: au88x0 - Avoid possible Oops at unbinding\n ALSA: usb-audio - Fix build error by consitification of rate list\n ASoC: core: Fix obscure leak of runtime array\n ALSA: pcm - Avoid GFP_ATOMIC in snd_pcm_link()\n ALSA: pcm: Constify the list in snd_pcm_hw_constraint_list\n ASoC: wm8996: Add 44.1kHz support\n ALSA: hda - Fix build of patch_sigmatel.c without CONFIG_SND_HDA_POWER_SAVE\n ASoC: mx27vis-aic32x4: Convert it to platform driver\n ALSA: hda - fix printing of high HDMI sample rates\n ALSA: ymfpci - Fix legacy registers on S3/S4 resume\n ALSA: control - Fixe a trailing white space error\n ALSA: hda - Add expose_enum_ctl flag to snd_hda_add_vmaster_hook()\n ALSA: hda - Add \"Mute-LED Mode\" enum control\n ...\n" }, { "commit": "754b9800779402924fffe456b49d557e15260cbf", "tree": "0e0441eca766616fccd8fc37a3885397efc6063a", "parents": [ "35cb8d9e18c0bb33b90d7e574abadbe23b65427d", "ea281a9ebaba3287130dbe15bb0aad6f798bb06b" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 22 09:42:04 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 22 09:42:04 2012 -0700" }, "message": "Merge branch \u0027x86-mce-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull MCE changes from Ingo Molnar.\n\n* \u0027x86-mce-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:\n x86/mce: Fix return value of mce_chrdev_read() when erst is disabled\n x86/mce: Convert static array of pointers to per-cpu variables\n x86/mce: Replace hard coded hex constants with symbolic defines\n x86/mce: Recognise machine check bank signature for data path error\n x86/mce: Handle \"action required\" errors\n x86/mce: Add mechanism to safely save information in MCE handler\n x86/mce: Create helper function to save addr/misc when needed\n HWPOISON: Add code to handle \"action required\" errors.\n HWPOISON: Clean up memory_failure() vs. __memory_failure()\n" } ], "next": "5375871d432ae9fc581014ac117b96aaee3cd0c7" }
