The changes are\n well contained and just plug into the driver new gpu functionality\n so they should be fairly regression proof. I just want to give\n them a bit of a run on the hw AMD kindly sent me.\n\n b) drm prime/dma-buf interface code. This is just infrastructure\n code to expose the dma-buf stuff to drm drivers and to userspace.\n I\u0027m not planning on pushing any driver support in this cycle\n (except maybe exynos), but I\u0027d like to get the infrastructure code\n in so for the next cycle I can start getting the driver support\n into the individual drivers. We have started driver support for\n i915, nouveau and udl along with I think exynos and omap in\n staging. However this code relies on the dma-buf tree being\n pulled into your tree first since it needs the latest interfaces\n from that tree.

This also applies to broken KVM devices that are unable to\ncorrectly forward the EDID data of the connected monitor but invent\ntheir own fantasy data.\n\nThis patch allows to specify an EDID data set to be used instead of\nprobing the monitor for it. It contains built-in data sets of frequently\nused screen resolutions. In addition, a particular EDID data set may be\nprovided in the /lib/firmware directory and loaded via the firmware\ninterface. The name is passed to the kernel as module parameter of the\ndrm_kms_helper module either when loaded\n options drm_kms_helper edid_firmware\u003dedid/1280x1024.bin\nor as kernel commandline parameter\n drm_kms_helper.edid_firmware\u003dedid/1280x1024.bin\n\nIt is also possible to restrict the usage of a specified EDID data set\nto a particular connector.

Ideally, EDID data of\nthe connected monitor should be used. They may be obtained through the\ndrm/cardX/cardX-\u003cconnector\u003e/edid entry in the /sys/devices PCI directory\nof a correctly working graphics adapter.\n\nIt is even possible to specify the name of an EDID data set on-the-fly\nvia the /sys/module interface, e.g.\necho edid/myedid.bin \u003e/sys/module/drm_kms_helper/parameters/edid_firmware\nThe new screen mode is considered when the related kernel function is\ncalled for the first time after the change.

However the kernel is trying to maximise\nmemory usage, hence there are usually few free pages in the system and\nbuggy code usually corrupts some crucial data.\n\nThis patch changes the buddy allocator to keep more free/protected pages\nand to interlace free/protected and allocated pages to increase the\nprobability of catching corruption.\n\nWhen the kernel is compiled with CONFIG_DEBUG_PAGEALLOC,\ndebug_guardpage_minorder defines the minimum order used by the page\nallocator to grant a request. The requested size will be returned with\nthe remaining pages used as guard pages.\n\nThe default value of debug_guardpage_minorder is zero: no change from\ncurrent behaviour.\n\n[akpm@linux-foundation.org: tweak documentation, s/flg/flag/]\nSigned-off-by: Stanislaw Gruszka \u003csgruszka@redhat.com\u003e\nCc: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: \"Rafael J.

Existing user space tools will\ncomplain about an unknown cpu type. In order to be compatible with\nexisting user space tools the `cpu_type\u0027 module parameter has been\nadded.

Everything\nelse must contain fixed values.\n\nThe \u0027event\u0027 value only supports a single event - HWSAMPLING with value\n0.\n\nThe \u0027count\u0027 value specifies the hardware sampling rate as it is passed\nto the CPU measurement facility.\n\nThe \u0027kernel\u0027 and \u0027user\u0027 flags can now be used to filter for samples\nwhen using hardware sampling.\n\nAdditionally also the following file will be created:\n/dev/oprofile/timer/enabled\n\nThis will always be the inverted value of /dev/oprofile/0/enabled. 0\nis not accepted without hardware sampling.\n\nSigned-off-by: Andreas Krebbel \u003ckrebbel@linux.vnet.ibm.com\u003e\nSigned-off-by: Robert Richter \u003crobert.richter@amd.com\u003e\n" }, { "commit": "89e0b9a3fd66d72f2d7b7f2d6d86fa56997cde27", "tree": "0e14a0ea2364dbb136e83403a1695817c0e993e2", "parents": [ "96f176a310e447966e45112fe4511b9d9fa0caf4" ], "author": { "name": "Sedat Dilek", "email": "sedat.dilek@googlemail.com", "time": "Mon Dec 05 23:08:32 2011 +0100" }, "committer": { "name": "Joerg Roedel", "email": "joerg.roedel@amd.com", "time": "Tue Dec 06 15:16:02 2011 +0100" }, "message": "iommu/amd: Fix typo in kernel-parameters.txt\n\nSigned-off-by: Sedat Dilek \u003csedat.dilek@gmail.com\u003e\nSigned-off-by: Joerg Roedel \u003cjoerg.roedel@amd.com\u003e\n" }, { "commit": "8360ee2f74bda2b794bdf4e23ab19d8b4e93807f", "tree": "65bd1dc8bb335a2b709638129949392647cb939d", "parents": [ "35d476996288af6a4aaa8b172bcd31decd233de7" ], "author": { "name": "Borislav Petkov", "email": "borislav.petkov@amd.com", "time": "Mon Nov 21 12:10:19 2011 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Dec 05 18:07:30 2011 +0100" }, "message": "x86, AMD: Correct align_va_addr documentation\n\nCommit dfb09f9b7ab0 (\"x86, amd: Avoid cache aliasing penalties\non AMD family 15h\") introduced a kernel command line parameter\ncalled \u0027align_va_addr\u0027 which still refers to arguments used in\nan earlier version of the patch and which got changed without\nupdating the documentation.

With its\nshared instruction cache there is a chance of generating an excessive\nnumber of cache cross-invalidates when running specific workloads on the\ncores of a compute module.\n\nThis excessive amount of cross-invalidations can be observed if cache\nlines backed by shared physical memory alias in bits [14:12] of their\nvirtual addresses, as those bits are used for the index generation.\n\nThis patch addresses the issue by clearing all the bits in the [14:12]\nslice of the file mapping\u0027s virtual address at generation time, thus\nforcing those bits the same for all mappings of a single shared library\nacross processes and, in doing so, avoids instruction cache aliases.\n\nIt also adds the command line option \"align_va_addr\u003d(32|64|on|off)\" with\nwhich virtual address alignment can be enabled for 32-bit or 64-bit x86\nindividually, or both, or be completely disabled.\n\nThis change leaves virtual region address allocation on other families\nand/or vendors unaffected.\n\nSigned-off-by: Borislav Petkov \u003cborislav.petkov@amd.com\u003e\nLink: http://lkml.kernel.org/r/1312550110-24160-2-git-send-email-bp@amd64.org\nSigned-off-by: H.

The Corsair\nPadlock v2 returns completely bogus data for its first read (possibly\nit returns the data in encrypted form even though the device is\nsupposed to be unlocked). The Feiya SD/SDHC card reader fails to\ncomplete the first READ(10) command after it is plugged in or after a\nnew card is inserted, returning a status code that indicates it thinks\nthe command was invalid, which prevents the kernel from retrying the\nread.\n\nSince the first read of a new device or a new medium is for the\npartition sector, the kernel is unable to retrieve the device\u0027s\npartition table. Users have to manually issue an \"hdparm -z\" or\n\"blockdev --rereadpt\" command before they can access the device.\n\nThis patch (as1470) works around the problem. It adds a new quirk\nflag, US_FL_INVALID_READ10, indicating that the first READ(10) should\nalways be retried immediately, as should any failing READ(10) commands\n(provided the preceding READ(10) command succeeded, to avoid getting\nstuck in a loop).
