A process may\nhave migrated to another node. Memory was allocated optimally for the prior\ncontext. sys_migrate_pages allows to shift the memory to the new node.\n\nsys_migrate_pages is also useful if the processes available memory nodes have\nchanged through cpuset operations to manually move the processes memory. Paul\nJackson is working on an automated mechanism that will allow an automatic\nmigration if the cpuset of a process is changed. However, a user may decide\nto manually control the migration.\n\nThis implementation is put into the policy layer since it uses concepts and\nfunctions that are also needed for mbind and friends. The patch also provides\na do_migrate_pages function that may be useful for cpusets to automatically\nmove memory. sys_migrate_pages does not modify policies in contrast to Ray\u0027s\nimplementation.\n\nThe current code here is based on the swap based page migration capability and\nthus is not able to preserve the physical layout relative to it containing\nnodeset (which may be a cpuset). When direct page migration becomes available\nthen the implementation needs to be changed to do a isomorphic move of pages\nbetween different nodesets. The current implementation simply evicts all\npages in source nodeset that are not in the target nodeset.\n\nPatch supports ia64, i386 and x86_64.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "19d534842cc39df1b568722c18f96ae24fb0e136", "tree": "bf4a0deac286079540f849dff8f8c030e2eba097", "parents": [ "bcf0f0d233fc76e7c59c7f731caad555428d0e8d" ], "author": { "name": "Brian Gerst", "email": "bgerst@didntduck.org", "time": "Fri Jan 06 00:12:18 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:39 2006 -0800" }, "message": "[PATCH] mpspec: remove unneeded packed attribute\n\nGCC 4.1 gives the following warning: include/asm/mpspec.h:79: warning:\n`packed\u0027 attribute ignored for field of type `unsigned char\u0027\n\nThe packed attribute isn\u0027t really necessary anyways so just remove it.\n\nSigned-off-by: Brian Gerst \u003cbgerst@didntduck.org\u003e\nAcked-by: Dave Jones \u003cdavej@codemonkey.org.uk\u003e\nCc: Andi Kleen \u003cak@muc.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f90b8116032f4216d260e31f966a3585319387ac", "tree": "c7234671ff0ee152e40dc0175fe46a0d7147641d", "parents": [ "6b7f430ee0a269464aa29159eb464e647ca313d3" ], "author": { "name": "Jordan Crouse", "email": "jordan.crouse@amd.com", "time": "Fri Jan 06 00:12:14 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:38 2006 -0800" }, "message": "[PATCH] Base support for AMD Geode GX/LX processors\n\nProvide basic support for the AMD Geode GX and LX processors.\n\nSigned-off-by: Jordan Crouse \u003cjordan.crouse@amd.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d832245d7cc16d50b29c1b708ccbe9c75ac376a3", "tree": "2fc22b6337fc433a6b392e9b008339d8031e8e1c", "parents": [ "e31b88ba49460653bab87423287bb68743f5de5c" ], "author": { "name": "Stephen Hemminger", "email": "shemminger@osdl.org", "time": "Fri Jan 06 00:12:12 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:38 2006 -0800" }, "message": "[PATCH] x86: fls() in asm\n\nThere is a single instruction on i386 to find largest set bit; so it makes\nsense to use it (like we use bfs for ffs()).\n\nSigned-off-by: Stephen Hemminger \u003cshemminger@osdl.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1855a2c4ce708b823b8b824f8b12937b45f5462a", "tree": "2aeed2e32d792652e43ae086d2522210715c9992", "parents": [ "c898ec16e83331abde39118e22e9e38335bbb950" ], "author": { "name": "Ashok Raj", "email": "ashok.raj@intel.com", "time": "Fri Jan 06 00:12:08 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:37 2006 -0800" }, "message": "[PATCH] x86: convert bigsmp to use flat physical mode\n\nWhen we bring up a new CPU via INIT/startup IPI messages, the CPU that\u0027s\ncoming up sends a xTPR message to the chipset.

However the only way to\nrelease tmpfs-swap is to MADV_REMOVE\". - Andrea Arcangeli\n\nDatabases want to use this feature to drop a section of their bufferpool\n(shared memory segments) - without writing back to disk/swap space.\n\nThis feature is also useful for supporting hot-plug memory on UML.\n\nConcerns raised by Andrew Morton:\n\n- \"We have no plan for holepunching! If we _do_ have such a plan (or\n might in the future) then what would the API look like? I think\n sys_holepunch(fd, start, len), so we should start out with that.\"\n\n- Using madvise is very weird, because people will ask \"why do I need to\n mmap my file before I can stick a hole in it?\"\n\n- None of the other madvise operations call into the filesystem in this\n manner. A broad question is: is this capability an MM operation or a\n filesytem operation? truncate, for example, is a filesystem operation\n which sometimes has MM side-effects. madvise is an mm operation and with\n this patch, it gains FS side-effects, only they\u0027re really, really\n significant ones.\"\n\nComments:\n\n- Andrea suggested the fs operation too but then it\u0027s more efficient to\n have it as a mm operation with fs side effects, because they don\u0027t\n immediatly know fd and physical offset of the range. It\u0027s possible to\n fixup in userland and to use the fs operation but it\u0027s more expensive,\n the vmas are already in the kernel and we can use them.\n\nShort term plan \u0026 Future Direction:\n\n- We seem to need this interface only for shmfs/tmpfs files in the short\n term. We have to add hooks into the filesystem for correctness and\n completeness. This is what this patch does.\n\n- In the future, plan is to support both fs and mmap apis also. This\n also involves (other) filesystem specific functions to be implemented.\n\n- Current patch doesn\u0027t support VM_NONLINEAR - which can be addressed in\n the future.\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3821af2fe13700cab6fd67367128fa180e43f8b8", "tree": "a70f63c24bd7d2ac8b25e3e4ee0ef6a50847aa67", "parents": [ "c865e5d99e25a171e8262fc0f7ba608568633c64" ], "author": { "name": "Stephen Hemminger", "email": "shemminger@osdl.org", "time": "Wed Dec 21 19:30:53 2005 -0800" }, "committer": { "name": "David S.

This waiter wakes up and after a few instructions it\nattempts to acquire the cv internal lock, but that lock is still held by\nthe thread calling pthread_cond_signal. So it goes to sleep and eventually\nthe signalling thread is scheduled in, unlocks the internal lock and wakes\nthe waiter again.\n\nNow, before 2003-09-21 NPTL was using FUTEX_REQUEUE in pthread_cond_signal\nto avoid this performance issue, but it was removed when locks were\nredesigned to the 3 state scheme (unlocked, locked uncontended, locked\ncontended).\n\nFollowing scenario shows why simply using FUTEX_REQUEUE in\npthread_cond_signal together with using lll_mutex_unlock_force in place of\nlll_mutex_unlock is not enough and probably why it has been disabled at\nthat time:\n\nThe number is value in cv-\u003e__data.__lock.\n thr1 thr2 thr3\n0 pthread_cond_wait\n1 lll_mutex_lock (cv-\u003e__data.__lock)\n0 lll_mutex_unlock (cv-\u003e__data.__lock)\n0 lll_futex_wait (\u0026cv-\u003e__data.__futex, futexval)\n0 pthread_cond_signal\n1 lll_mutex_lock (cv-\u003e__data.__lock)\n1 pthread_cond_signal\n2 lll_mutex_lock (cv-\u003e__data.__lock)\n2 lll_futex_wait (\u0026cv-\u003e__data.__lock, 2)\n2 lll_futex_requeue (\u0026cv-\u003e__data.__futex, 0, 1, \u0026cv-\u003e__data.__lock)\n # FUTEX_REQUEUE, not FUTEX_CMP_REQUEUE\n2 lll_mutex_unlock_force (cv-\u003e__data.__lock)\n0 cv-\u003e__data.__lock \u003d 0\n0 lll_futex_wake (\u0026cv-\u003e__data.__lock, 1)\n1 lll_mutex_lock (cv-\u003e__data.__lock)\n0 lll_mutex_unlock (cv-\u003e__data.__lock)\n # Here, lll_mutex_unlock doesn\u0027t know there are threads waiting\n # on the internal cv\u0027s lock\n\nNow, I believe it is possible to use FUTEX_REQUEUE in pthread_cond_signal,\nbut it will cost us not one, but 2 extra syscalls and, what\u0027s worse, one of\nthese extra syscalls will be done for every single waiting loop in\npthread_cond_*wait.\n\nWe would need to use lll_mutex_unlock_force in pthread_cond_signal after\nrequeue and lll_mutex_cond_lock in pthread_cond_*wait after lll_futex_wait.\n\nAnother alternative is to do the unlocking pthread_cond_signal needs to do\n(the lock can\u0027t be unlocked before lll_futex_wake, as that is racy) in the\nkernel.\n\nI have implemented both variants, futex-requeue-glibc.patch is the first\none and futex-wake_op{,-glibc}.patch is the unlocking inside of the kernel.\n The kernel interface allows userland to specify how exactly an unlocking\noperation should look like (some atomic arithmetic operation with optional\nconstant argument and comparison of the previous futex value with another\nconstant).\n\nIt has been implemented just for ppc*, x86_64 and i?86, for other\narchitectures I\u0027m including just a stub header which can be used as a\nstarting point by maintainers to write support for their arches and ATM\nwill just return -ENOSYS for FUTEX_WAKE_OP.

Fixing that is hard, while SYSEMU is easier to implement.\n\n* This version of the patch includes some suggestions of Jeff Dike to avoid\n adding any instructions to the syscall fast path, plus some other little\n changes, by myself, to make it work even when the syscall is executed with\n SYSENTER (but I\u0027m unsure about them). It has been widely tested for quite a\n lot of time.\n\n* Various fixed were included to handle the various switches between\n various states, i.e. when for instance a syscall entry is traced with one of\n PT_SYSCALL / _SYSEMU / _SINGLESTEP and another one is used on exit.\n Basically, this is done by remembering which one of them was used even after\n the call to ptrace_notify().\n\n* We\u0027re combining TIF_SYSCALL_EMU with TIF_SYSCALL_TRACE or TIF_SINGLESTEP\n to make do_syscall_trace() notice that the current syscall was started with\n SYSEMU on entry, so that no notification ought to be done in the exit path;\n this is a bit of a hack, so this problem is solved in another way in next\n patches.\n\n* Also, the effects of the patch:\n\"Ptrace - i386: fix Syscall Audit interaction with singlestep\"\nare cancelled; they are restored back in the last patch of this series.\n\nDetailed descriptions of the patches doing this kind of processing follow (but\nI\u0027ve already summed everything up).\n\n* Fix behaviour when changing interception kind #1.\n\n In do_syscall_trace(), we check the status of the TIF_SYSCALL_EMU flag\n only after doing the debugger notification; but the debugger might have\n changed the status of this flag because he continued execution with\n PTRACE_SYSCALL, so this is wrong. This patch fixes it by saving the flag\n status before calling ptrace_notify().\n\n* Fix behaviour when changing interception kind #2:\n avoid intercepting syscall on return when using SYSCALL again.\n\n A guest process switching from using PTRACE_SYSEMU to PTRACE_SYSCALL\n crashes.\n\n The problem is in arch/i386/kernel/entry.S. The current SYSEMU patch\n inhibits the syscall-handler to be called, but does not prevent\n do_syscall_trace() to be called after this for syscall completion\n interception.\n\n The appended patch fixes this. It reuses the flag TIF_SYSCALL_EMU to\n remember \"we come from PTRACE_SYSEMU and now are in PTRACE_SYSCALL\", since\n the flag is unused in the depicted situation.\n\n* Fix behaviour when changing interception kind #3:\n avoid intercepting syscall on return when using SINGLESTEP.\n\n When testing 2.6.9 and the skas3.v6 patch, with my latest patch and had\n problems with singlestepping on UML in SKAS with SYSEMU. It looped\n receiving SIGTRAPs without moving forward. EIP of the traced process was\n the same for all SIGTRAPs.\n\nWhat\u0027s missing is to handle switching from PTRACE_SYSCALL_EMU to\nPTRACE_SINGLESTEP in a way very similar to what is done for the change from\nPTRACE_SYSCALL_EMU to PTRACE_SYSCALL_TRACE.\n\nI.e., after calling ptrace(PTRACE_SYSEMU), on the return path, the debugger is\nnotified and then wake ups the process; the syscall is executed (or skipped,\nwhen do_syscall_trace() returns 0, i.e. when using PTRACE_SYSEMU), and\ndo_syscall_trace() is called again. Since we are on the return path of a\nSYSEMU\u0027d syscall, if the wake up is performed through ptrace(PTRACE_SYSCALL),\nwe must still avoid notifying the parent of the syscall exit. Now, this\nbehaviour is extended even to resuming with PTRACE_SINGLESTEP.\n\nSigned-off-by: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c3c433e4f33afe255389ba3b1a003dc8deb3de9a", "tree": "071304e15e21e0a93c17050000a682f4ae1a98c1", "parents": [ "57c4ce3cbfba1bb0da7f37b9328a713cbd5d0919" ], "author": { "name": "Shaohua Li", "email": "shaohua.li@intel.com", "time": "Sat Sep 03 15:57:07 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:06:18 2005 -0700" }, "message": "[PATCH] add suspend/resume for timer\n\nThe timers lack .suspend/.resume methods.
