driver\n\nPreliminary support for the Intel 5100 MCH. CE and UE errors are reported\nalong with the current DIMM label information and other memory parameters.\n\nReasons why this is preliminary:\n\n1) This chip has 2 independent memory controllers which, for best\n perforance, use interleaved accesses to the DDR2 memory. This\n architecture does not map very well to the current edac data structures\n which depend on symmetric channel access to the interleaved data.\n Without core changes, the best I could do for now is to map both memory\n controllers to different csrows (first all ranks of controller 0, then\n all ranks of controller 1). Someone much more familiar with the edac\n core than I will probably need to come up with a more general data\n structure to handle the interleaving and de-interleaving of the two\n memory controllers.\n\n2) I have not yet tackled the de-interleaving of the rank/controller\n address space into the physical address space of the CPU. There is\n nothing fundamentally missing, it is just ending up to be a lot of\n code, and I\u0027d rather keep it separate for now, esp since it doesn\u0027t\n work yet...\n\n3) The code depends on a particular i5100 chip select to DIMM mainboard\n chip select mapping. This mapping seems obvious to me in order to\n support dual and single ranked memory, but it is not unique and DIMM\n labels could be wrong on other mainboards. There is no way to query\n this mapping that I know of.\n\n4) The code requires that the i5100 is in 32GB mode. Only 4 ranks per\n controller, 2 ranks per DIMM are supported. I do not have hardware\n (nor do I expect to have hardware anytime soon) for the 48GB (6 ranks\n per controller) mode.\n\n5) The serial presence detect code should be broken out into a \"real\"\n i2c driver so that decode-dimms.pl can work.\n\nSigned-off-by: Arthur Jones \u003cajones@riverbed.com\u003e\nSigned-off-by: Doug Thompson \u003cdougthompson@xmission.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "33670fa296860283f04a7975b8c790f101e43a6e", "tree": "61162737edbffe696f4f9b13998d192cd3be3f75", "parents": [ "c180eebe1390c2076ead6a9bc95a02efb994edb7" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Fri Jul 25 01:49:02 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jul 25 10:53:48 2008 -0700" }, "message": "fuse: nfs export special lookups\n\nImplement the get_parent export operation by sending a LOOKUP request with\n\"..\" as the name.\n\nImplement looking up an inode by node ID after it has been evicted from\nthe cache.

This is returned by\n\n posix_lock_file() for sleeping locks to mean that the lock has been\n queued on the block list, and will be woken up when it might become\n available and needs to be retried (either fl_lmops-\u003efl_notify() is\n called or fl_wait is woken up).\n\n f_op-\u003elock() to mean either the above, or that the filesystem will\n call back with fl_lmops-\u003efl_grant() when the result of the locking\n operation is known. The filesystem can do this for sleeping as well\n as non-sleeping locks.\n\nThis is to make sure, that return values of -EAGAIN and -EINPROGRESS by\nfilesystems are not mistaken to mean an asynchronous locking.\n\nThis also makes error handling in fs/locks.c and lockd/svclock.c slightly\ncleaner.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: \"J.

With these patches, msgmni has a registered notification\nroutine that recomputes msgmni value upon memory add/remove or ipc\nnamespace creation/ removal.\n\nWhen msgmni is changed from user space (i.e. value written to the proc\nfile), that notification routine is unregistered, and the way to make it\nregistered back is to write a negative value into the proc file. This is\nthe \"magical positive-versus-negative number trick\".\n\nTo fix this, a new proc file is introduced: /proc/sys/kernel/auto_msgmni.\nThis file acts as ON/OFF for msgmni automatic recomputing.\n\nWith this patch, the process is the following:\n1) kernel boots in \"automatic recomputing mode\"\n /proc/sys/kernel/msgmni contains the value that has been computed (depends\n on lowmem)\n /proc/sys/kernel/automatic_msgmni contains \"1\"\n\n2) echo \u003cval\u003e \u003e /proc/sys/kernel/msgmni\n . sets msg_ctlmni to \u003cval\u003e\n . de-activates automatic recomputing (i.e. if, say, some memory is added\n msgmni won\u0027t be recomputed anymore)\n . /proc/sys/kernel/automatic_msgmni now contains \"0\"\n\n3) echo \"0\" \u003e /proc/sys/kernel/automatic_msgmni\n . de-activates msgmni automatic recomputing\n this has the same effect as 2) except that msg_ctlmni\u0027s value stays\n blocked at its current value)\n\n3) echo \"1\" \u003e /proc/sys/kernel/automatic_msgmni\n . recomputes msgmni\u0027s value based on the current available memory size\n and number of ipc namespaces\n . re-activates automatic recomputing for msgmni.\n\nSigned-off-by: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nCc: Solofo Ramangalahy \u003cSolofo.Ramangalahy@bull.net\u003e\nSigned-off-by: Andrew Morton
