However, some\n drivers don\u0027t support getting large merged segments coming back\n from *_map_sg().\n\n Most drivers don\u0027t have this problem; it is safe to say Y here.\n\nIt\u0027s out of date. Long ago, drivers didn\u0027t have a way to tell IOMMUs\nabout their segment length limit (that is, the maximum segment length\nthat they can handle). So IOMMUs merged as many segments as possible\nand gave too large segments to drivers.\n\ndma_get_max_seg_size() was introduced to solve the above\nproblem. Device drives can use the API to tell IOMMU about the maximum\nsegment length that they can handle. In addition, the default limit\n(64K) should be safe for everyone.\n\nSo this config option seems to be unnecessary.\n\nNote that this config option just enables users to disable the virtual\nmerging by default.

With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant.

A few\nother archs have also mentioned some interest in using dtc.\nTherefore, this patch moves dtc and libfdt from arch/powerpc into\nscripts, where it can be used by any architecture.\n\nThe vast bulk of this patch is a literal move, the rest is adjusting\nthe various Makefiles to use dtc and libfdt correctly from their new\nlocations.\n\nSigned-off-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "adf213c43898f2324cfc35c315556bc21cb65b31", "tree": "039fc299644c05bcf711f80f5c0fe44b8402dc3f", "parents": [ "8d82ffd15e59febf2c597067a777526958b7f769" ], "author": { "name": "Hugh Dickins", "email": "hugh@veritas.com", "time": "Mon Apr 06 11:01:15 2009 +0000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Wed Apr 15 15:23:53 2009 +1000" }, "message": "powerpc: Allow 256kB pages with SHMEM\n\nNow that shmem\u0027s divisions by zero and SHMEM_MAX_BYTES are fixed,\nlet powerpc 256kB pages coexist with CONFIG_SHMEM again.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "cb93d568e1ed2596e27f35b39241fe83955d9b26", "tree": "aced19e0491bc6d8b18d83f41aa2e3514b5ecc6d", "parents": [ "7e875e9dc8af70d126fa632446e967327ac3fdda" ], "author": { "name": "Geert Uytterhoeven", "email": "Geert.Uytterhoeven@sonycom.com", "time": "Thu Apr 02 06:25:41 2009 +0000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Tue Apr 07 15:19:00 2009 +1000" }, "message": "powerpc: Correct dependency of KEXEC\n\ncommit 28794d34ecb6815a3fa0a4256027c9b081a17c5f (\"powerpc/kconfig: Kill\nPPC_MULTIPLATFORM\") broke KEXEC, by making it dependent on BOOK3S, while it\nshould be PPC_BOOK3S.\n\nSigned-off-by: Geert Uytterhoeven \u003cGeert.Uytterhoeven@sonycom.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "ae6e59caefd8d4097ccb096c95df95ec7e52fe88", "tree": "f72b77d41c9f5a3b18fb52e505d60dba2ad913a5", "parents": [ "0221c81b1b8eb0cbb6b30a0ced52ead32d2b4e4c", "f379188958ae8af30105eb1f27d0e0abf6a51558" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Tue Apr 07 12:54:08 2009 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Tue Apr 07 12:54:08 2009 +1000" }, "message": "Merge branch \u0027next\u0027 of master.kernel.org:/pub/scm/linux/kernel/git/galak/powerpc into merge\n" }, { "commit": "811158b147a503fbdf9773224004ffd32002d1fe", "tree": "0a11dcfefe721bfc38ea9f1f4a238822dbae0dda", "parents": [ "4e76c5ccd5ac9bd003467d3bb0f49b18572dd4cd", "b26e0ed4936b743b693a4cc1413561fa3e4eaf65" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 03 15:24:35 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 03 15:24:35 2009 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial: (28 commits)\n trivial: Update my email address\n trivial: NULL noise: drivers/mtd/tests/mtd_*test.c\n trivial: NULL noise: drivers/media/dvb/frontends/drx397xD_fw.h\n trivial: Fix misspelling of \"Celsius\".\n trivial: remove unused variable \u0027path\u0027 in alloc_file()\n trivial: fix a pdlfush -\u003e pdflush typo in comment\n trivial: jbd header comment typo fix for JBD_PARANOID_IOFAIL\n trivial: wusb: Storage class should be before const qualifier\n trivial: drivers/char/bsr.c: Storage class should be before const qualifier\n trivial: h8300: Storage class should be before const qualifier\n trivial: fix where cgroup documentation is not correctly referred to\n trivial: Give the right path in Documentation example\n trivial: MTD: remove EOL from MODULE_DESCRIPTION\n trivial: Fix typo in bio_split()\u0027s documentation\n trivial: PWM: fix of #endif comment\n trivial: fix typos/grammar errors in Kconfig texts\n trivial: Fix misspelling of firmware\n trivial: cgroups: documentation typo and spelling corrections\n trivial: Update contact info for Jochen Hein\n trivial: fix typo \"resgister\" -\u003e \"register\"\n ...\n" }, { "commit": "6a11f75b6a17b5d9ac5025f8d048382fd1f47377", "tree": "a3415cd897823975b927f89a233d2703bf97ba2b", "parents": [ "610a77e04a8d9fe8764dc484e2182fa251ce1cc2" ], "author": { "name": "Akinobu Mita", "email": "akinobu.mita@gmail.com", "time": "Tue Mar 31 15:23:17 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 01 08:59:13 2009 -0700" }, "message": "generic debug pagealloc\n\nCONFIG_DEBUG_PAGEALLOC is now supported by x86, powerpc, sparc64, and\ns390.

simplification of implementation with 256KB pages we still assume\n2-level paging. As a side effect this leads to wasting extra memory space\nreserved for PTE tables: only 1/4 of pages allocated for PTEs are\nactually used. But this may be an acceptable trade-off to achieve the\nhigh performance we have with big PAGE_SIZEs in some applications (e.g.\nRAID).\n\nAlso with 256KB PAGE_SIZE we increase THREAD_SIZE up to 32KB to minimize\nthe risk of stack overflows in the cases of on-stack arrays, which size\ndepends on the page size (e.g. multipage BIOs, NTFS, etc.).\n\nWith 256KB PAGE_SIZE we need to decrease the PKMAP_ORDER at least down\nto 9, otherwise all high memory (2 ^ 10 * PAGE_SIZE \u003d\u003d 256MB) we\u0027ll be\noccupied by PKMAP addresses leaving no place for vmalloc. We do not\nseparate PKMAP_ORDER for 256K from 16K/64K PAGE_SIZE here; actually that\nvalue of 10 in support for 16K/64K had been selected rather intuitively.\nThus now for all cases of PAGE_SIZE on ppc44x (including the default, 4KB,\none) we have 512 pages for PKMAP.\n\nBecause ELF standard supports only page sizes up to 64K, then you should\nuse binutils later than 2.17.50.0.3 with \u0027-zmax-page-size\u0027 set to 256K\nfor building applications, which are to be run with the 256KB-page sized\nkernel. If using the older binutils, then you should patch them like follows:\n\n\t--- binutils/bfd/elf32-ppc.c.orig\n\t+++ binutils/bfd/elf32-ppc.c\n\n\t-#define ELF_MAXPAGESIZE 0x10000\n\t+#define ELF_MAXPAGESIZE 0x40000\n\nOne more restriction we currently have with 256KB page sizes is inability\nto use shmem safely, so, for now, the 256KB is available only if you turn\nthe CONFIG_SHMEM option off (another variant is to use BROKEN).\nThough, if you need shmem with 256KB pages, you can always remove the !SHMEM\ndependency in \u0027config PPC_256K_PAGES\u0027, and use the workaround available here:\n http://lkml.org/lkml/2008/12/19/20\n\nSigned-off-by: Yuri Tikhonov \u003cyur@emcraft.com\u003e\nSigned-off-by: Ilya Yanok \u003cyanok@emcraft.com\u003e\nSigned-off-by: Josh Boyer \u003cjwboyer@linux.vnet.ibm.com\u003e\n" }, { "commit": "d0839118f396f6d7af553e99ad204aa2b3209cde", "tree": "30435e0748176ac46344a6c0d97fb3dd7108b492", "parents": [ "f7a0be456f1bdcb6dec81c1e4e47e2b7205eba95" ], "author": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Wed Jan 28 13:25:29 2009 -0600" }, "committer": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Wed Jan 28 18:17:02 2009 -0600" }, "message": "powerpc/fsl: Ensure PCI_QUIRKS are enabled for FSL_PCI\n\nThe FSL PCI code depends on PCI quirks being enabled to function\nproperly.

On E500v2 pages up to 4 GB are supported.\n\nHowever, a page must be aligned to a multiple of the page\u0027s size. I.e.\n256 MB pages must aligned to a 256 MB boundary. This was enforced by a\nrequirement that the physical and virtual addresses of the start of lowmem\nbe aligned to 256 MB. Clearly requiring 1GB or 4GB alignment to allow\npages of that size isn\u0027t acceptable.\n\nTo solve this, I simply have adjust_total_lowmem() take alignment into\naccount when it decides what size pages to use. Give it PAGE_OFFSET \u003d\n0x7000_0000, PHYSICAL_START \u003d 0x3000_0000, and 2GB of RAM, and it will map\npages like this:\nPA 0x3000_0000 VA 0x7000_0000 Size 256 MB\nPA 0x4000_0000 VA 0x8000_0000 Size 1 GB\nPA 0x8000_0000 VA 0xC000_0000 Size 256 MB\nPA 0x9000_0000 VA 0xD000_0000 Size 256 MB\nPA 0xA000_0000 VA 0xE000_0000 Size 256 MB\n\nBecause the lowmem mapping code now takes alignment into account,\nPHYSICAL_ALIGN can be lowered from 256 MB to 64 MB. Even lower might be\npossible. The lowmem code will work down to 4 kB but it\u0027s possible some of\nthe boot code will fail before then. Poor alignment will force small pages\nto be used, which combined with the limited number of TLB1 pages available,\nwill result in very little memory getting mapped. So alignments less than\n64 MB probably aren\u0027t very useful anyway.\n\nSigned-off-by: Trent Piepho \u003ctpiepho@freescale.com\u003e\nSigned-off-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\n" }, { "commit": "52c275fe70df8619e9430d01917d2e72e9011aec", "tree": "693d6df30577a9d02f84f3df9527652eaa6d1a41", "parents": [ "802bdea875ed8c682bb30f71d762ce727ab8bb87" ], "author": { "name": "Josh Boyer", "email": "jwboyer@linux.vnet.ibm.com", "time": "Tue Jan 20 05:16:36 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Jan 28 17:15:51 2009 +1100" }, "message": "powerpc: Remove arch/ppc cruft from Kconfig\n\nRemove some leftover cruft from the arch/ppc days\n\nSigned-off-by: Josh Boyer \u003cjwboyer@linux.vnet.ibm.com\u003e\nAcked-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "ee6a093222549ac0c72cfd296c69fa5e7d6daa34", "tree": "8f1788edc08009b80ee299b843cdc7bf3ac4bcdc", "parents": [ "1a94bc34768e463a93cb3751819709ab0ea80a01" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Jan 14 14:14:00 2009 +0100" }, "committer": { "name": "Heiko Carstens", "email": "heiko.carstens@de.ibm.com", "time": "Wed Jan 14 14:15:17 2009 +0100" }, "message": "[CVE-2009-0029] powerpc: Enable syscall wrappers for 64-bit\n\nThis enables the use of syscall wrappers to do proper sign extension\nfor 64-bit programs.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\n" }, { "commit": "2b79d6962322facfd377a402730e4b381af95a40", "tree": "cc0ea598b663ead982b14b706b9f24d96493130a", "parents": [ "9b635642bce0500bdc7331ce8eeca97907b77117" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Tue Jan 06 18:49:17 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Jan 08 16:25:18 2009 +1100" }, "message": "powerpc: enable dynamic ftrace\n\nThis patch enables dynamic ftrace.

So the same kernel can be used as production and\nkdump kernel.\n\nThis patch incorporates the changes suggested by Paul Mackerras to avoid\nGOT use and to avoid two copies of the code.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Mohan Kumar M \u003cmohan@in.ibm.com\u003e\nSigned-off-by: Michael Ellerman \u003cmichael@ellerman.id.au\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "a02efb906d12c9d4eb2ab7c59049ba9545e5412d", "tree": "bf1f6467978ec63a22f42299ecac2ee7f7e73336", "parents": [ "84dfcb4b318463cd4883b6a19937824f49aee564", "2515ddc6db8eb49a79f0fe5e67ff09ac7c81eab4" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue Oct 21 15:52:04 2008 +1100" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue Oct 21 15:52:04 2008 +1100" }, "message": "Merge commit \u0027origin\u0027 into master\n\nManual merge of:\n\n\tarch/powerpc/Kconfig\n\tarch/powerpc/include/asm/page.h" }, { "commit": "dbc1c5c250cbedccf3571597d156e581e34b2944", "tree": "771df5aa8e938a6caf35bd06a9e9be6589421b84", "parents": [ "a3ba68f969b2407b6809a840f6ff45ab0eb06f84" ], "author": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Mon Oct 20 08:03:46 2008 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue Oct 21 15:19:11 2008 +1100" }, "message": "powerpc: Remove Kconfig support for PPC_MERGE\n\nThere are no users of PPC_MERGE in tree so we can get rid of it.\nIt was a hold over from the arch/ppc days.\n\nSigned-off-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "606576ce816603d9fe1fb453a88bc6eea16ca709", "tree": "7c6844ff4d75f249df49e9e5fe97062d301c3a1f", "parents": [ "c2db8054c1eaf99983d8deee347876b01c26c2cf" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Mon Oct 06 19:06:12 2008 -0400" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Oct 20 18:27:03 2008 +0200" }, "message": "ftrace: rename FTRACE to FUNCTION_TRACER\n\nDue to confusion between the ftrace infrastructure and the gcc profiling\ntracer \"ftrace\", this patch renames the config options from FTRACE to\nFUNCTION_TRACER.

It provides a way to stop and resume execution of all tasks in\na cgroup by writing in the cgroup filesystem.\n\nThe freezer subsystem in the container filesystem defines a file named\nfreezer.state. Writing \"FROZEN\" to the state file will freeze all tasks\nin the cgroup. Subsequently writing \"RUNNING\" will unfreeze the tasks in\nthe cgroup. Reading will return the current state.\n\n* Examples of usage :\n\n # mkdir /containers/freezer\n # mount -t cgroup -ofreezer freezer /containers\n # mkdir /containers/0\n # echo $some_pid \u003e /containers/0/tasks\n\nto get status of the freezer subsystem :\n\n # cat /containers/0/freezer.state\n RUNNING\n\nto freeze all tasks in the container :\n\n # echo FROZEN \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n FREEZING\n # cat /containers/0/freezer.state\n FROZEN\n\nto unfreeze all tasks in the container :\n\n # echo RUNNING \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n RUNNING\n\nThis is the basic mechanism which should do the right thing for user space\ntask in a simple scenario.\n\nIt\u0027s important to note that freezing can be incomplete. In that case we\nreturn EBUSY. This means that some tasks in the cgroup are busy doing\nsomething that prevents us from completely freezing the cgroup at this\ntime. After EBUSY, the cgroup will remain partially frozen -- reflected\nby freezer.state reporting \"FREEZING\" when read. The state will remain\n\"FREEZING\" until one of these things happens:\n\n\t1) Userspace cancels the freezing operation by writing \"RUNNING\" to\n\t\tthe freezer.state file\n\t2) Userspace retries the freezing operation by writing \"FROZEN\" to\n\t\tthe freezer.state file (writing \"FREEZING\" is not legal\n\t\tand returns EIO)\n\t3) The tasks that blocked the cgroup from entering the \"FROZEN\"\n\t\tstate disappear from the cgroup\u0027s set of tasks.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: export thaw_process]\nSigned-off-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nAcked-by: Serge E.

Super-cascaded (64 bit) timers (1-2-3-4).\n This is also straightforward to implement when needed, all timers\n should be marked as \"requested\" and configured as appropriate.\n\nSigned-off-by: Anton Vorontsov \u003cavorontsov@ru.mvista.com\u003e\nSigned-off-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\n" }, { "commit": "677aa9f77e8de3791b481a0cec6c8b84d1eec626", "tree": "4a3cdc6b1653231af31f045dcbaebb806a04d78d", "parents": [ "7fa09f24b477ad41b821713eba757b3aa7a2864a" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Sat May 17 00:01:36 2008 -0400" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri May 23 22:49:18 2008 +0200" }, "message": "ftrace: add have dynamic ftrace config for archs\n\nNow that ftrace is being ported to other architectures, it has become\napparent that DYNAMIC_FTRACE is dependent on whether or not that\narchitecture implements dynamic ftrace.
