On large CPU\nsystems, the difference between the estimated and real value of\nNR_FREE_PAGES can be very high.

cwq-\u003enr_active underflow\n\ncwq-\u003enr_active is used to keep track of how many work items are active\nfor the cpu workqueue, where \u0027active\u0027 is defined as either pending on\nglobal worklist or executing. This is used to implement the\nmax_active limit and workqueue freezing. If a work item is queued\nafter nr_active has already reached max_active, the work item doesn\u0027t\nincrement nr_active and is put on the delayed queue and gets activated\nlater as previous active work items retire.\n\ntry_to_grab_pending() which is used in the cancellation path\nunconditionally decremented nr_active whether the work item being\ncancelled is currently active or delayed, so cancelling a delayed work\nitem makes nr_active underflow. This breaks max_active enforcement\nand triggers BUG_ON() in destroy_workqueue() later on.\n\nThis patch fixes this bug by adding a flag WORK_STRUCT_DELAYED, which\nis set while a work item in on the delayed list and making\ntry_to_grab_pending() decrement nr_active iff the work item is\ncurrently active.\n\nThe addition of the flag enlarges cwq alignment to 256 bytes which is\ngetting a bit too large.

Then,\nacpi_pci_osc_control_set() will run _OSC queries in a loop until\nthe mask of _OSC control bits returned by the BIOS is equal to the\nmask passed to it.

The lglock provides fast access to the per-cpu lists\nto add and remove files. It also provides a snapshot of all the per-cpu lists\n(although this is very slow).\n\nOne difficulty with this approach is that a file can be removed from the list\nby another CPU. We must track which per-cpu list the file is on with a new\nvariale in the file struct (packed into a hole on 64-bit archs). Scalability\ncould suffer if files are frequently removed from different cpu\u0027s list.\n\nHowever loads with frequent removal of files imply short interval between\nadding and removing the files, and the scheduler attempts to avoid moving\nprocesses too far away. Also, even in the case of cross-CPU removal, the\nhardware has much more opportunity to parallelise cacheline transfers with N\ncachelines than with 1.\n\nA worst-case test of 1 CPU allocating files subsequently being freed by N CPUs\ndegenerates to contending on a single lock, which is no worse than before. When\nmore than one CPU are allocating files, even if they are always freed by\ndifferent CPUs, there will be more parallelism than the single-lock case.\n\nTesting results:\n\nOn a 2 socket, 8 core opteron, I measure the number of times the lock is taken\nto remove the file, the number of times it is removed by the same CPU that\nadded it, and the number of times it is removed by the same node that added it.\n\nBooting: locks\u003d 25049 cpu-hits\u003d 23174 (92.5%) node-hits\u003d 23945 (95.6%)\nkbuild -j16 locks\u003d2281913 cpu-hits\u003d2208126 (96.8%) node-hits\u003d2252674 (98.7%)\ndbench 64 locks\u003d4306582 cpu-hits\u003d4287247 (99.6%) node-hits\u003d4299527 (99.8%)\n\nSo a file is removed from the same CPU it was added by over 90% of the time.\nIt remains within the same node 95% of the time.\n\nTim Chen ran some numbers for a 64 thread Nehalem system performing a compile.\n\n throughput\n2.6.34-rc2 24.5\n+patch 24.9\n\n us sys idle IO wait (in %)\n2.6.34-rc2 51.25 28.25 17.25 3.25\n+patch 53.75 18.5 19 8.75\n\nSo significantly less CPU time spent in kernel code, higher idle time and\nslightly higher throughput.\n\nSingle threaded performance difference was within the noise of microbenchmarks.\nThat is not to say penalty does not exist, the code is larger and more memory\naccesses required so it will be slightly slower.\n\nCc: linux-kernel@vger.kernel.org\nCc: Tim Chen \u003ctim.c.chen@linux.intel.com\u003e\nCc: Andi Kleen \u003cak@linux.intel.com\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "2dc91abe03d8ce6dd7f9251faffafca5f6b9e85d", "tree": "1712fcb512310a80a7d2c7f92b30ce91750efaf1", "parents": [ "d996b62a8df1d935b01319bf8defb95b5709f7b8" ], "author": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Wed Aug 18 04:37:37 2010 +1000" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Aug 18 08:35:48 2010 -0400" }, "message": "lglock: introduce special lglock and brlock spin locks\n\nlglock: introduce special lglock and brlock spin locks\n\nThis patch introduces \"local-global\" locks (lglocks).
