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" }, { "commit": "5375871d432ae9fc581014ac117b96aaee3cd0c7", "tree": "be98e8255b0f927fb920fb532a598b93fa140dbe", "parents": [ "b57cb7231b2ce52d3dda14a7b417ae125fb2eb97", "dfbc2d75c1bd47c3186fa91f1655ea2f3825b0ec" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 21 18:55:10 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 21 18:55:10 2012 -0700" }, "message": "Merge branch \u0027next\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc\n\nPull powerpc merge from Benjamin Herrenschmidt:\n \"Here\u0027s the powerpc batch for this merge window. It is going to be a\n bit more nasty than usual as in touching things outside of\n arch/powerpc mostly due to the big iSeriesectomy :-) We finally got\n rid of the bugger (legacy iSeries support) which was a PITA to\n maintain and that nobody really used anymore.\n\n Here are some of the highlights:\n\n - Legacy iSeries is gone. Thanks Stephen ! There\u0027s still some bits\n and pieces remaining if you do a grep -ir series arch/powerpc but\n they are harmless and will be removed in the next few weeks\n hopefully.\n\n - The \u0027fadump\u0027 functionality (Firmware Assisted Dump) replaces the\n previous (equivalent) \"pHyp assisted dump\"... it\u0027s a rewrite of a\n mechanism to get the hypervisor to do crash dumps on pSeries, the\n new implementation hopefully being much more reliable. Thanks\n Mahesh Salgaonkar.\n\n - The \"EEH\" code (pSeries PCI error handling \u0026 recovery) got a big\n spring cleaning, motivated by the need to be able to implement a\n new backend for it on top of some new different type of firwmare.\n\n The work isn\u0027t complete yet, but a good chunk of the cleanups is\n there. Note that this adds a field to struct device_node which is\n not very nice and which Grant objects to. I will have a patch soon\n that moves that to a powerpc private data structure (hopefully\n before rc1) and we\u0027ll improve things further later on (hopefully\n getting rid of the need for that pointer completely).

In that case, the amount of time\nnecessary to runtime-resume the given device (e.g. the MMC\ncontroller) is often substantially greater than the time needed to\nrun its driver\u0027s runtime resume callback. That may hurt performance\nin some situations, because user data may need to wait for the\ndevice to become operational, so we should make it possible to\nprevent that from happening.\n\nFor this reason, introduce a new sysfs attribute for devices,\npower/pm_qos_resume_latency_us, allowing user space to specify the\nupper bound of the time necessary to bring the (runtime-suspended)\ndevice up after the resume of it has been requested. However, make\nthat attribute appear only for the devices whose drivers declare\nsupport for it by calling the (new) dev_pm_qos_expose_latency_limit()\nhelper function with the appropriate initial value of the attribute.\n\nSigned-off-by: Rafael J.

This worked in the past, because registers without a\nexplicit default were assumed to have a default value of 0. This was changed in\ncommit b03622a8 (\"regmap: Ensure rbtree syncs registers set to zero properly\").\nAs a result registers, which have a raw default value of 0 are now assumed to\nhave no default. This again can result in unnecessary writes when syncing the\ncache. It will also result in unnecessary reads for e.g. the first update\noperation. In the case where readback is not possible this will even let the\nupdate operation fail, if the register has not been written to before.\n\nSo this patch removes the check. Instead it adds a check to ignore raw defaults\nfor registers which are volatile, since those registers are not cached.\n\nSigned-off-by: Lars-Peter Clausen \u003clars@metafoo.de\u003e\nSigned-off-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nCc: stable@vger.kernel.org\n" }, { "commit": "7c95149b7f1f61201b12c73c4862a41bf2428961", "tree": "33917dbbd8b8cbbf917262e42baf3a528b752149", "parents": [ "a556d5b58345ccf51826b9ceac078072f830738b" ], "author": { "name": "Rafael J.

"message": "dma-buf: Introduce dma buffer sharing mechanism\n\nThis is the first step in defining a dma buffer sharing mechanism.\n\nA new buffer object dma_buf is added, with operations and API to allow easy\nsharing of this buffer object across devices.\n\nThe framework allows:\n- creation of a buffer object, its association with a file pointer, and\n associated allocator-defined operations on that buffer. This operation is\n called the \u0027export\u0027 operation.\n- different devices to \u0027attach\u0027 themselves to this exported buffer object, to\n facilitate backing storage negotiation, using dma_buf_attach() API.\n- the exported buffer object to be shared with the other entity by asking for\n its \u0027file-descriptor (fd)\u0027, and sharing the fd across.\n- a received fd to get the buffer object back, where it can be accessed using\n the associated exporter-defined operations.\n- the exporter and user to share the scatterlist associated with this buffer\n object using map_dma_buf and unmap_dma_buf operations.\n\nAtleast one \u0027attach()\u0027 call is required to be made prior to calling the\nmap_dma_buf() operation.\n\nCouple of building blocks in map_dma_buf() are added to ease introduction\nof sync\u0027ing across exporter and users, and late allocation by the exporter.\n\nFor this first version, this framework will work with certain conditions:\n- *ONLY* exporter will be allowed to mmap to userspace (outside of this\n framework - mmap is not a buffer object operation),\n- currently, *ONLY* users that do not need CPU access to the buffer are\n allowed.\n\nMore details are there in the documentation patch.\n\nThis is based on design suggestions from many people at the mini-summits[1],\nmost notably from Arnd Bergmann \u003carnd@arndb.de\u003e, Rob Clark \u003crob@ti.com\u003e and\nDaniel Vetter \u003cdaniel@ffwll.ch\u003e.\n\nThe implementation is inspired from proof-of-concept patch-set from\nTomasz Stanislawski \u003ct.stanislaws@samsung.com\u003e, who demonstrated buffer sharing\nbetween two v4l2 devices.

They are\nonly needed by their children when there\u0027s some data to transfer,\nso they may be suspended for the majority of time and resumed\non demand, when the children have data to send or receive. For this\npurpose, however, their power.ignore_children flags have to be set,\nor the PM core wouldn\u0027t allow them to be suspended while their\nchildren were active.\n\nUnfortunately, in some situations it may take too much time to\nresume such devices so that they can assist their children in\ntransferring data. For example, if such a device belongs to a PM\ndomain which goes to the \"power off\" state when that device is\nsuspended, it may take too much time to restore power to the\ndomain in response to the request from one of the device\u0027s\nchildren. In that case, if the parent\u0027s resume time is critical,\nthe domain should stay in the \"power on\" state, although it still may\nbe desirable to power manage the parent itself (e.g. by manipulating\nits clock).\n\nIn general, device PM QoS may be used to address this problem.\nNamely, if the device\u0027s children added PM QoS latency constraints\nfor it, they would be able to prevent it from being put into an\noverly deep low-power state. However, in some cases the devices\nneeding to be serviced are not the immediate children of a\n\"children-ignoring\" device, but its grandchildren or even less\ndirect descendants. In those cases, the entity wanting to add a\nPM QoS request for a given device\u0027s ancestor that ignores its\nchildren will have to find it in the first place, so introduce a new\nhelper function that may be used to achieve that.

Consider the following scenario, currently used in\ndrivers/base/firmware_class.c:\n\n...\nif (usermodehelper_is_disabled())\n goto out;\n\n/* Do actual work */\n...\n\nout:\n return err;\n\nNothing prevents someone from disabling usermodehelpers just after the check\nin the \u0027if\u0027 condition, which means that it is quite possible to try doing the\n\"actual work\" with usermodehelpers disabled, leading to undesirable\nconsequences.\n\nIn particular, this race condition in _request_firmware() causes task freezing\nfailures whenever suspend/hibernation is in progress because, it wrongly waits\nto get the firmware/microcode image from userspace when actually the\nusermodehelpers are disabled or userspace has been frozen.\nSome of the example scenarios that cause freezing failures due to this race\nare those that depend on userspace via request_firmware(), such as x86\nmicrocode module initialization and microcode image reload.\n\nPrevious discussions about this issue can be found at:\nhttp://thread.gmane.org/gmane.linux.kernel/1198291/focus\u003d1200591\n\nThis patch adds proper synchronization to fix this issue.\n\nIt is to be noted that this patchset fixes the freezing failures but doesn\u0027t\nremove the warnings. IOW, it does not attempt to add explicit synchronization\nto x86 microcode driver to avoid requesting microcode image at inopportune\nmoments. Because, the warnings were introduced to highlight such cases, in the\nfirst place. And we need not silence the warnings, since we take care of the\n*real* problem (freezing failure) and hence, after that, the warnings are\npretty harmless anyway.\n\nSigned-off-by: Srivatsa S.
