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. This works\nbecause the size of a dma_buf is invariant over it\u0027s lifetime. The\nexporter would obviously need to fall back to coherent mappings for\nboth ranges if a legacy clients maps the coherent range and the\narchitecture cannot suppor conflicting caching policies. Also, this\nwould obviously be optional and userspace needs to be able to fall\nback to coherent mappings.\n\nv2:\n- Spelling fixes from Rob Clark.\n- Compile fix for !DMA_BUF from Rob Clark.\n- Extend commit message to explain how explicitly cache managed mmap\n support could be added later.\n- Extend the documentation with implementations notes for exporters\n that need to manually fake coherency.\n\nChange-Id: Ia8f2ae5d8a1b1c87ed12ca1c89d7bf2067239ee4\nCc: Rob Clark \u003crob.clark@linaro.org\u003e\nCc: Rebecca Schultz Zavin \u003crebecca@android.com\u003e\nSigned-Off-by: Daniel

However, as it\u0027s been determined recently,\nthere are multiple reasons not to do so, inlcuding:\n\n * The caller really doesn\u0027t control the runtime PM usage counters,\n because user space can access them through sysfs and effectively\n block runtime PM. That means using pm_runtime_suspend() or\n pm_runtime_get_sync() to suspend devices during system suspend\n may or may not work.\n\n * If a driver calls pm_runtime_suspend() from its .suspend()\n callback, it causes the subsystem\u0027s .runtime_suspend() callback to\n be executed, which leads to the call sequence:\n\n subsys-\u003esuspend(dev)\n driver-\u003esuspend(dev)\n pm_runtime_suspend(dev)\n subsys-\u003eruntime_suspend(dev)\n\n recursive from the subsystem\u0027s point of view. For some subsystems\n that may actually work (e.g. the platform bus type), but for some\n it will fail in a rather spectacular fashion (e.g. PCI). In each\n case it means a layering violation.\n\n * Both the subsystem and the driver can provide .suspend_noirq()\n callbacks for system suspend that can do whatever the\n .runtime_suspend() callbacks do just fine, so it really isn\u0027t\n necessary to call pm_runtime_suspend() during system suspend.\n\n * The runtime PM\u0027s handling of wakeup devices is usually different\n from the system suspend\u0027s one, so .runtime_suspend() may simply be\n inappropriate for system suspend.\n\n * System suspend is supposed to work even if CONFIG_PM_RUNTIME is\n unset.\n\n * The runtime PM workqueue is frozen before system suspend, so if\n whatever the driver is going to do during system suspend depends\n on it, that simply won\u0027t work.\n\nStill, there is a good reason to allow pm_runtime_resume() to\nsucceed during system suspend and resume (for instance, some\nsubsystems and device drivers may legitimately use it to ensure that\ntheir devices are in full-power states before suspending them).\nMoreover, there is no reason to prevent runtime PM callbacks from\nbeing executed in parallel with the system suspend/resume .prepare()\nand .complete() callbacks and the code removed by commit\ne8665002477f0278f84f898145b1f141ba26ee26 went too far in this\nrespect. On the other hand, runtime PM callbacks, including\n.runtime_resume(), must not be executed during system suspend\u0027s\n\"late\" stage of suspending devices and during system resume\u0027s \"early\"\ndevice resume stage.\n\nTaking all of the above into consideration, make the PM core\nacquire a runtime PM reference to every device and resume it if\nthere\u0027s a runtime PM resume request pending right before executing\nthe subsystem-level .suspend() callback for it. Make the PM core\ndrop references to all devices right after executing the\nsubsystem-level .resume() callbacks for them. Additionally,\nmake the PM core disable the runtime PM framework for all devices\nduring system suspend, after executing the subsystem-level .suspend()\ncallbacks for them, and enable the runtime PM framework for all\ndevices during system resume, right before executing the\nsubsystem-level .resume() callbacks for them.\n\nSigned-off-by: Rafael J.

Still needs more testing though.\n Using it to get rid of the gpio early_initcall madness, or to replace\n the ASoC internal probe deferral code would be ideal.\nv2: - added locking so it should no longer be utterly broken in that regard\n - remove device from deferred list at device_del time.\n - Still completely untested with any real use case, but has been\n boot tested.\n\nChange-Id: Iaf6bb62f70c2d82c6cccbe468bc5007b1989af93\nSigned-off-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\nCc: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nCc: Arnd Bergmann \u003carnd@arndb.de\u003e\nCc: Dilan Lee \u003cdilee@nvidia.com\u003e\nCc: Manjunath GKondaiah \u003cmanjunath.gkondaiah@linaro.org\u003e\nCc: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: Tony Lindgren \u003ctony@atomide.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nReviewed-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nAcked-by: David Daney \u003cdavid.daney@cavium.com\u003e\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\nSigned-off-by: Michael Bohan \u003cmbohan@codeaurora.org\u003e\n" }, { "commit": "3a4ffe930a2d2dad07604fe74d21b878decc6461", "tree": "d0374dd4c93c5efc3d46addb36b0ce38e94cc39e", "parents": [ "33cb4f345687a27e3fece0a7fcf78ac2e7b0a7d6" ], "author": { "name": "Lee Jones", "email": "lee.jones@linaro.org", "time": "Sat Mar 17 09:17:49 2012 +0000" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Mon Apr 09 14:54:22 2012 -0700" }, "message": "drivers/base: fix compiler warning in SoC export driver - idr should be ida\n\nThis fixes:\n note: expected ‘struct ida *’ but argument is of type ‘struct idr *’\n warning: passing argument 1 of ‘ida_pre_get’ from incompatible pointer type\n\nReported-by: Arnd Bergman \u003carnd@arndb.de\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\nSigned-off-by: Lee Jones \u003clee.jones@linaro.org\u003e\nSigned-off-by: Axel Lin \u003caxel.lin@gmail.com\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "33cb4f345687a27e3fece0a7fcf78ac2e7b0a7d6", "tree": "2f843a196f9745b1bbfbd11eda391013b559345d", "parents": [ "0034102808e0dbbf3a2394b82b1bb40b5778de9e" ], "author": { "name": "Axel Lin", "email": "axel.lin@gmail.com", "time": "Tue Mar 20 16:32:39 2012 +0800" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Mon Apr 09 14:54:22 2012 -0700" }, "message": "drivers/base: Remove unneeded spin_lock_init call for soc_lock\n\nsoc_lock is already initialized by DEFINE_SPINLOCK.\n\nSigned-off-by: Axel Lin \u003caxel.lin@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "9109a22de417cce528f15ae2e51ebb3d826f1bf5", "tree": "31668612bbb2430986dfc38d2556506272275992", "parents": [ "71b54d4483ea92b333613d376a95509668e36282" ], "author": { "name": "Benoit Goby", "email": "benoit@android.com", "time": "Thu Aug 13 09:40:42 2009 -0700" }, "committer": { "name": "Colin Cross", "email": "ccross@android.com", "time": "Mon Apr 09 13:53:08 2012 -0700" }, "message": "drivers: power: Add watchdog timer to catch drivers which lockup during suspend.\n\nRather than hard-lock the kernel, dump the suspend thread stack and\nBUG() when a driver takes too long to suspend.

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). Thanks Gavin\n Shan.\n\n - I dug into our exception \u0026 interrupt handling code to improve the\n way we do lazy interrupt handling (and make it work properly with\n \"edge\" triggered interrupt sources), and while at it found \u0026 fixed\n a wagon of issues in those areas, including adding support for page\n fault retry \u0026 fatal signals on page faults.\n\n - Your usual random batch of small fixes \u0026 updates, including a bunch\n of new embedded boards, both Freescale and APM based ones, etc...\"\n\nI fixed up some conflicts with the generalized irq-domain changes from\nGrant Likely, hopefully correctly.\n\n* \u0027next\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (141 commits)\n powerpc/ps3: Do not adjust the wrapper load address\n powerpc: Remove the rest of the legacy iSeries include files\n powerpc: Remove the remaining CONFIG_PPC_ISERIES pieces\n init: Remove CONFIG_PPC_ISERIES\n powerpc: Remove FW_FEATURE ISERIES from arch code\n tty/hvc_vio: FW_FEATURE_ISERIES is no longer selectable\n powerpc/spufs: Fix double unlocks\n powerpc/5200: convert mpc5200 to use of_platform_populate()\n powerpc/mpc5200: add options to mpc5200_defconfig\n powerpc/mpc52xx: add a4m072 board support\n powerpc/mpc5200: update mpc5200_defconfig to fit for charon board\n Documentation/powerpc/mpc52xx.txt: Checkpatch cleanup\n powerpc/44x: Add additional device support for APM821xx SoC and Bluestone board\n powerpc/44x: Add support PCI-E for APM821xx SoC and Bluestone board\n MAINTAINERS: Update PowerPC 4xx tree\n powerpc/44x: The bug fixed support for APM821xx SoC and Bluestone board\n powerpc: document the FSL MPIC message register binding\n powerpc: add support for MPIC message register API\n powerpc/fsl: Added aliased MSIIR register address to MSI node in dts\n powerpc/85xx: mpc8548cds - add 36-bit dts\n ...\n" }, { "commit": "f8974cb71310a05632aada76be6a27576d61e609", "tree": "c0b6f59333796c95aa2de9a2eb755e9b68599b71", "parents": [ "c207f3a43194e108dda43dc9a1ce507335cff6b9", "0f22dd395fc473cee252b9af50249b8e0f32fde7" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 21 10:30:03 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 21 10:30:03 2012 -0700" }, "message": "Merge tag \u0027dt-for-linus\u0027 of git://git.secretlab.ca/git/linux-2.6\n\nPull core device tree changes for Linux v3.4 from Grant Likely:\n \"This branch contains a minor documentation addition, a utility\n function for parsing string properties needed by some of the new ARM\n platforms, disables dynamic DT code that isn\u0027t used anywhere but on a\n few PPC machines, and exports DT node compatible data to userspace via\n UEVENT properties.

Still needs more testing though.\n Using it to get rid of the gpio early_initcall madness, or to replace\n the ASoC internal probe deferral code would be ideal.\nv2: - added locking so it should no longer be utterly broken in that regard\n - remove device from deferred list at device_del time.\n - Still completely untested with any real use case, but has been\n boot tested.\n\nSigned-off-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\nCc: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nCc: Arnd Bergmann \u003carnd@arndb.de\u003e\nCc: Dilan Lee \u003cdilee@nvidia.com\u003e\nCc: Manjunath GKondaiah \u003cmanjunath.gkondaiah@linaro.org\u003e\nCc: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: Tony Lindgren \u003ctony@atomide.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nReviewed-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nAcked-by: David Daney \u003cdavid.daney@cavium.com\u003e\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "f9353e70bcebd00cd182d946083afd7d8eddd259", "tree": "a13460f9e9e88796067c24f0853c8a386413f022", "parents": [ "a0941e562e8008804f9fe4400315ceb164752fac" ], "author": { "name": "Mark Brown", "email": "broonie@opensource.wolfsonmicro.com", "time": "Mon Mar 05 23:28:49 2012 +0000" }, "committer": { "name": "Mark Brown", "email": "broonie@opensource.wolfsonmicro.com", "time": "Mon Mar 05 23:49:24 2012 +0000" }, "message": "regmap: Fix rbtree block base in sync\n\nOtherwise we\u0027ll end up running with bogus register numbers.\n\nSigned-off-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\n" }, { "commit": "994f5db65ef4b83db0321842bd43c6bc0a51f000", "tree": "633121617abdf0799462b87ed19dd4cc7b2f2f56", "parents": [ "19694b5ea1d3a723dafe9544b5ee9a935414dc28" ], "author": { "name": "Mark Brown", "email": "broonie@opensource.wolfsonmicro.com", "time": "Mon Mar 05 23:31:39 2012 +0000" }, "committer": { "name": "Mark Brown", "email": "broonie@opensource.wolfsonmicro.com", "time": "Mon Mar 05 23:48:50 2012 +0000" }, "message": "regcache: Make sure we sync register 0 in an rbtree cache\n\nMost of the current users have register 0 as a volatile register or don\u0027t\nhave a register 0 so it\u0027s not been apparent that it\u0027s not getting synced.\n\nSigned-off-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\n" }, { "commit": "48ed00031681c373ff81e78fd248710fe4cddda0", "tree": "dd90809d6017924ee528114a4205ab8cfd8422af", "parents": [ "643161ace2a7624fd0106ede12ae43bcbbfc1de0", "b642631d38c28fefd1232a6b96713eb54b60130d" ], "author": { "name": "Rafael J.
