(previously we had one SMP debugging\nvariant per architecture, plus a separate generic one for UP builds)\n\nAlso, i\u0027ve enhanced the rwlock debugging facility, it will now track\nwrite-owners.

I have fixed a problem with the ia64 version of\nbuild_sched_domains(), but a similar fix still needs to be made to the\ngeneric build_sched_domains() in kernel/sched.c.\n\nThe \"dynamic sched domains\" functionality has recently been merged into\n2.6.13-rcN that sees the dynamic declaration of a cpu-exclusive (a.k.a.\n\"isolated\") cpuset and rebuilds the CPU Scheduler sched domains and sched\ngroups to separate away the CPUs in this cpu-exclusive cpuset from the\nremainder of the non-isolated CPUs. This allows the non-isolated CPUs to\ncompletely ignore the isolated CPUs when doing load-balancing.\n\nUnfortunately, build_sched_domains() expects that a sched domain will\ninclude all the CPUs of each node in the domain, i.e., that no node will\nbelong in both an isolated cpuset and a non-isolated cpuset. Declaring a\ncpuset that violates this presumption will produce flawed data structures\nand will oops the kernel.\n\nTo trigger the problem (on a NUMA system with \u003e1 CPUs per node):\n cd /dev/cpuset\n mkdir newcpuset\n cd newcpuset\n echo 0 \u003ecpus\n echo 0 \u003emems\n echo 1 \u003ecpu_exclusive\n\nI have fixed this shortcoming for ia64 NUMA (with multiple CPUs per node).\nA similar shortcoming exists in the generic build_sched_domains() (in\nkernel/sched.c) for NUMA, and that needs to be fixed also. The fix\ninvolves dynamically allocating sched_group_nodes[] and\nsched_group_allnodes[] for each invocation of build_sched_domains(), rather\nthan using global arrays for these structures. Care must be taken to\nremember kmalloc() addresses so that arch_destroy_sched_domains() can\nproperly kfree() the new dynamic structures.\n\nSigned-off-by: John Hawkes \u003chawkes@sgi.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "54d5d42404e7705cf3804593189e963350d470e5", "tree": "7cf8a7fce163b19672193d8cf4ef6a7f6c131d9e", "parents": [ "f63ed39c578a2a2d067356a85ce7c28a7c795d8a" ], "author": { "name": "Ashok Raj", "email": "ashok.raj@intel.com", "time": "Tue Sep 06 15:16:15 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 16:57:15 2005 -0700" }, "message": "[PATCH] x86/x86_64: deferred handling of writes to /proc/irqxx/smp_affinity\n\nWhen handling writes to /proc/irq, current code is re-programming rte\nentries directly.

So with this patch, we leave NetBSD as the lonely one that\nbehaves differently here with #2.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "4db8699bcfa8faddb5727b1cb010a4d9b8a42e8c", "tree": "eb4cb14927ed9cf4507f875cd69fe35f87b3b3bc", "parents": [ "fd589e0b662c1ea8cfb1e0d20d60a2510979865b" ], "author": { "name": "Venkatesh Pallipadi", "email": "venkatesh.pallipadi@intel.com", "time": "Fri Jul 29 16:15:00 2005 -0700" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Fri Aug 26 15:09:24 2005 -0700" }, "message": "[IA64] Add ACPI based P-state support\n\nPatch to support P-state transitions on ia64.

While i\u0027m sure Martin is\ntrying to solve a real problem, we must not hard-code an incomplete and\ninsufficient approach into a syscall, because syscalls are pretty much\nfor eternity. I am quite strongly convinced that this syscall must not\nhit v2.6.13 in its current form.\n\nFirstly, the syscall lacks basic syscall design: e.g. it allows the\nglobal setting of VM policy for unprivileged users. (!) [ Imagine an\nOracle installation and a SAP installation on the same NUMA box fighting\nover the \u0027optimal\u0027 setting for this flag. What will they do? Will they\ntry to set the flag to their own preferred value every second or so? ]\n\nSecondly, it was added based on a single datapoint from Martin:\n\n http://marc.theaimsgroup.com/?l\u003dlinux-mm\u0026m\u003d111763597218177\u0026w\u003d2\n\nwhere Martin characterizes the numbers the following way:\n\n \u0027 Run-to-run variability for \"make -j\" is huge, so these numbers aren\u0027t\n terribly useful except to see that with reclaim the benchmark still\n finishes in a reasonable amount of time. \u0027\n\nin other words: the fundamental problem has likely not been solved, only\na tendential move into the right direction has been observed, and a\nhandful of numbers were picked out of a set of hugely variable results,\nwithout showing the variability data. How much variance is there\nrun-to-run?\n\nI\u0027d really suggest to first walk the walk and see what\u0027s needed to get\nstable \u0026 predictable kernel compilation numbers on that NUMA box, before\nadding random syscalls to tune a particular aspect of the VM ... which\napproach might not even matter once the whole picture has been analyzed\nand understood!\n\nThe third, most important point is that the syscall exposes VM tuning\ninternals in a completely unstructured way. What sense does it make to\nhave a _GLOBAL_ per-node setting for \u0027should we go to another node for\nreclaim\u0027? If then it might make sense to do this per-app, via numalib or\nso.\n\nThe change is minimalistic in that it doesnt remove the syscall and the\nunderlying infrastructure changes, only the user-visible changes.

The uncached allocator was formerly part of the SN2\nmspec driver but there are several other users of it so it has been split\noff from the driver.\n\nThe generic allocator can be used by device driver to manage special memory\netc. The generic allocator is based on the allocator from the sym53c8xx_2\ndriver.\n\nVarious users on ia64 needs uncached memory. The SGI SN architecture requires\nit for inter-partition communication between partitions within a large NUMA\ncluster. The specific user for this is the XPC code. Another application is\nlarge MPI style applications which use it for synchronization, on SN this can\nbe done using special \u0027fetchop\u0027 operations but it also benefits non SN\nhardware which may use regular uncached memory for this purpose. Performance\nof doing this through uncached vs cached memory is pretty substantial. This\nis handled by the mspec driver which I will push out in a seperate patch.\n\nRather than creating a specific allocator for just uncached memory I came up\nwith genalloc which is a generic purpose allocator that can be used by device\ndrivers and other subsystems as they please. For instance to handle onboard\ndevice memory. It was derived from the sym53c7xx_2 driver\u0027s allocator which\nis also an example of a potential user (I am refraining from modifying sym2\nright now as it seems to have been under fairly heavy development recently).\n\nOn ia64 memory has various properties within a granule, ie. it isn\u0027t safe to\naccess memory as uncached within the same granule as currently has memory\naccessed in cached mode. The regular system therefore doesn\u0027t utilize memory\nin the lower granules which is mixed in with device PAL code etc. The\nuncached driver walks the EFI memmap and pulls out the spill uncached pages\nand sticks them into the uncached pool. Only after these chunks have been\nutilized, will it start converting regular cached memory into uncached memory.\nHence the reason for the EFI related code additions.\n\nSigned-off-by: Jes Sorensen \u003cjes@wildopensource.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "753ee728964e5afb80c17659cc6c3a6fd0a42fe0", "tree": "41c9a7700d0858c1f77c5bdaba97e5b636f69b06", "parents": [ "bfbb38fb808ac23ef44472d05d9bb36edfb49ed0" ], "author": { "name": "Martin Hicks", "email": "mort@sgi.com", "time": "Tue Jun 21 17:14:41 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Tue Jun 21 18:46:14 2005 -0700" }, "message": "[PATCH] VM: early zone reclaim\n\nThis is the core of the (much simplified) early reclaim.

Run-to-run variability for \"make -j\" is huge, so\nthese numbers aren\u0027t terribly useful except to seee that with reclaim\nthe benchmark still finishes in a reasonable amount of time.\n\nI also looked at the NUMA hit/miss stats for the \"make -j\" runs and the\nreclaim doesn\u0027t make any difference when the machine is thrashing away.\n\nDoing a \"make -j8\" on a single node that is filled with page cache pages\ntakes 700 seconds with reclaim turned on and 735 seconds without reclaim\n(due to remote memory accesses).\n\nThe simple zone_reclaim syscall program is at\nhttp://www.bork.org/~mort/sgi/zone_reclaim.c\n\nSigned-off-by: Martin Hicks \u003cmort@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "4ea78729b8dbfc400fe165a57b90a394a7275a54", "tree": "cc8d7def737ca5a4189481466d1e4164eef98313", "parents": [ "7b404b3459db1326bbdc7085edb1f58b98da5826" ], "author": { "name": "Matthew Chapman", "email": "matthewc@hp.com", "time": "Tue Jun 21 16:19:20 2005 -0700" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Jun 21 16:19:20 2005 -0700" }, "message": "[IA64] ptrace and restore_sigcontext() allow ar.rsc.pl\u003d\u003d0\n\nThis patch fixes handling of accesses to ar.rsc via ptrace \u0026 restore_sigcontext\n[With Thanks to Chris Wright for noticing the restore_sigcontext path]\n\nSigned-off-by: Matthew Chapman \u003cmatthewc@hp.com\u003e\nAcked-by: David Mosberger \u003cdavidm@hpl.hp.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "0393eed5c3220c9c3823a09a2d02329b8ff08b45", "tree": "c465ee4c3a0322a4e6533f4e1ec0968b8b254907", "parents": [ "52a0de2cd2d3da8f90d88e2eccb63d0cadd6ae26" ], "author": { "name": "Ken Chen", "email": "kenneth.w.chen@intel.com", "time": "Tue Jun 21 14:40:31 2005 -0700" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Jun 21 14:40:31 2005 -0700" }, "message": "[IA64] fix nested_dtlb_miss handler for hugetlb address\n\nThe nested_dtlb_miss handler currently does not handle fault from\nhugetlb address correctly.
