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. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them. I\u0027ve undone some of that, but\n in case there\u0027s something left where \u0027counter\u0027 would be\n better than \u0027event\u0027 we can undo that on an individual basis\n instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.

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.

The arches may later undefine ZONE_DMA if their arch code has\nbeen verified to not depend on ZONE_DMA.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Matthew Wilcox \u003cwilly@debian.org\u003e\nCc: James Bottomley \u003cJames.Bottomley@steeleye.com\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "31ee4b2f40994e8b21691f85cdd4052551a789b7", "tree": "1bb167e720e25a2ea9a5168b21cc882f85b18fa8", "parents": [ "31cb4bd31a48f62105d037ad53192b94d4c08f53" ], "author": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Mon Feb 05 21:18:31 2007 +0100" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Mon Feb 05 21:18:31 2007 +0100" }, "message": "[S390] Calibrate delay and bogomips.\n\nPreset the bogomips number to the cpu capacity value reported by\nstore system information in SYSIB 1.2.2.

Our hardware does\nnot have any bits left in the pte for a hw noexec bit, so this is a\ndifferent approach using shadow page tables and a special addressing\nmode that allows separate address spaces for code and data.\n\nAs a special feature of our \"secondary-space\" addressing mode, separate\npage tables can be specified for the translation of data addresses\n(storage operands) and instruction addresses. The shadow page table is\nused for the instruction addresses and the standard page table for the\ndata addresses.\nThe shadow page table is linked to the standard page table by a pointer\nin page-\u003elru.next of the struct page corresponding to the page that\ncontains the standard page table (since page-\u003eprivate is not really\nprivate with the pte_lock and the page table pages are not in the LRU\nlist).\nDepending on the software bits of a pte, it is either inserted into\nboth page tables or just into the standard (data) page table. Pages of\na vma that does not have the VM_EXEC bit set get mapped only in the\ndata address space. Any try to execute code on such a page will cause a\npage translation exception. The standard reaction to this is a SIGSEGV\nwith two exceptions: the two system call opcodes 0x0a77 (sys_sigreturn)\nand 0x0aad (sys_rt_sigreturn) are allowed. They are stored by the\nkernel to the signal stack frame. Unfortunately, the signal return\nmechanism cannot be modified to use an SA_RESTORER because the\nexception unwinding code depends on the system call opcode stored\nbehind the signal stack frame.\n\nThis feature requires that user space is executed in secondary-space\nmode and the kernel in home-space mode, which means that the addressing\nmodes need to be switched and that the noexec protection only works\nfor user space.\nAfter switching the addressing modes, we cannot use the mvcp/mvcs\ninstructions anymore to copy between kernel and user space. A new\nmvcos instruction has been added to the z9 EC/BC hardware which allows\nto copy between arbitrary address spaces, but on older hardware the\npage tables need to be walked manually.\n\nSigned-off-by: Gerald Schaefer \u003cgeraldsc@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "62fb2ba3d870305e246c6cb317609c1dc2c9dd0b", "tree": "16ca23c98933b729e638cfa44e944464abac5830", "parents": [ "3b4709a6cd0578d129d032a5dec9dc2684b71b3a" ], "author": { "name": "Al Viro", "email": "viro@ftp.linux.org.uk", "time": "Wed Dec 13 00:34:59 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Wed Dec 13 09:05:52 2006 -0800" }, "message": "[PATCH] appldata_mem dependes on vm counters\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "88032b322a38b37335c8cb2e3473a45c81d280eb", "tree": "cd722ab15b18a10f6b1aa50656b8da713ee8b799", "parents": [ "63f3861d2fbf8ccbad1386ac9ac8b822c036ea00", "028d9b3cc62cb9dd31f1b5929edb3c23612cfccc" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Fri Dec 08 11:21:55 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Fri Dec 08 11:21:55 2006 -0800" }, "message": "Merge branch \u0027for-linus\u0027 of git://git390.osdl.marist.edu/pub/scm/linux-2.6\n\n* \u0027for-linus\u0027 of git://git390.osdl.marist.edu/pub/scm/linux-2.6:\n [S390] Poison init section before freeing it.\n [S390] Use add_active_range() and free_area_init_nodes().\n [S390] Virtual memmap for s390.\n [S390] Update documentation for dynamic subchannel mapping.\n [S390] Use dev-\u003egroups for adding/removing the subchannel attribute group.\n [S390] Support for disconnected devices reappearing on another subchannel.\n [S390] subchannel lock conversion.\n [S390] Some preparations for the dynamic subchannel mapping patch.\n [S390] runtime switch for qdio performance statistics\n [S390] New DASD feature for ERP related logging\n [S390] add reset call handler to the ap bus.\n [S390] more workqueue fixes.\n [S390] workqueue fixes.\n [S390] uaccess_pt: add missing down_read() and convert to is_init().\n" } ], "next": "f0d1b0b30d250a07627ad8b9fbbb5c7cc08422e8" }
