The new semaphore code does\nthis on down():\n\n spin_lock_irqsave(\u0026sem-\u003elock, flags);\n if (likely(sem-\u003ecount \u003e 0))\n sem-\u003ecount--;\n else\n __down(sem);\n spin_unlock_irqrestore(\u0026sem-\u003elock, flags);\n\nand this on up():\n\n spin_lock_irqsave(\u0026sem-\u003elock, flags);\n if (likely(list_empty(\u0026sem-\u003ewait_list)))\n sem-\u003ecount++;\n else\n __up(sem);\n spin_unlock_irqrestore(\u0026sem-\u003elock, flags);\n\nwhere __up() does:\n\n list_del(\u0026waiter-\u003elist);\n waiter-\u003eup \u003d 1;\n wake_up_process(waiter-\u003etask);\n\nand where __down() does this in essence:\n\n list_add_tail(\u0026waiter.list, \u0026sem-\u003ewait_list);\n waiter.task \u003d task;\n waiter.up \u003d 0;\n for (;;) {\n [...]\n spin_unlock_irq(\u0026sem-\u003elock);\n timeout \u003d schedule_timeout(timeout);\n spin_lock_irq(\u0026sem-\u003elock);\n if (waiter.up)\n return 0;\n }\n\nthe fastpath looks good and obvious, but note the following property of\nthe contended path: if there\u0027s a task on the -\u003ewait_list, the up() of\nthe current owner will \"pass over\" ownership to that waiting task, in a\nwake-one manner, via the waiter-\u003eup flag and by removing the waiter from\nthe wait list.\n\nThat is all and fine in principle, but as implemented in\nkernel/semaphore.c it also creates a nasty, hidden source of contention!\n\nThe contention comes from the following property of the new semaphore\ncode: the new owner owns the semaphore exclusively, even if it is not\nrunning yet.\n\nSo if the old owner, even if just a few instructions later, does a\ndown() [lock_kernel()] again, it will be blocked and will have to wait\non the new owner to eventually be scheduled (possibly on another CPU)!\nOr if another task gets to lock_kernel() sooner than the \"new owner\"\nscheduled, it will be blocked unnecessarily and for a very long time\nwhen there are 2000 tasks running.\n\nI.e. the implementation of the new semaphores code does wake-one and\nlock ownership in a very restrictive way - it does not allow\nopportunistic re-locking of the lock at all and keeps the scheduler from\npicking task order intelligently.\n\nThis kind of scheduling, with 2000 AIM7 processes running, creates awful\ncross-scheduling between those 2000 tasks, causes reduced parallelism, a\nthrottled runqueue length and a lot of idle time. With increasing number\nof CPUs it causes an exponentially worse behavior in AIM7, as the chance\nfor a newly woken new-owner task to actually run anytime soon is less\nand less likely.\n\nNote that it takes just a tiny bit of contention for the \u0027new-semaphore\ncatastrophy\u0027 to happen: the wakeup latencies get added to whatever small\ncontention there is, and quickly snowball out of control!\n\nI believe Yanmin\u0027s findings and numbers support this analysis too.\n\nThe best fix for this problem is to use the same scheduling logic that\nthe kernel/mutex.c code uses: keep the wake-one behavior (that is OK and\nwanted because we do not want to over-schedule), but also allow\nopportunistic locking of the lock even if a wakee is already \"in\nflight\".\n\nThe patch below implements this new logic. With this patch applied the\nAIM7 regression is largely fixed on my quad testbox:\n\n # v2.6.25 vanilla:\n ..................\n Tasks Jobs/Min JTI Real CPU Jobs/sec/task\n 2000 56096.4 91 207.5 789.7 0.4675\n 2000 55894.4 94 208.2 792.7 0.4658\n\n # v2.6.26-rc1-166-gc0a1811 vanilla:\n ...................................\n Tasks Jobs/Min JTI Real CPU Jobs/sec/task\n 2000 33230.6 83 350.3 784.5 0.2769\n 2000 31778.1 86 366.3 783.6 0.2648\n\n # v2.6.26-rc1-166-gc0a1811 + semaphore-speedup:\n ...............................................\n Tasks Jobs/Min JTI Real CPU Jobs/sec/task\n 2000 55707.1 92 209.0 795.6 0.4642\n 2000 55704.4 96 209.0 796.0 0.4642\n\ni.e. a 67% speedup. We are now back to within 1% of the v2.6.25\nperformance levels and have zero idle time during the test, as expected.\n\nBtw., interactivity also improved dramatically with the fix - for\nexample console-switching became almost instantaneous during this\nworkload (which after all is running 2000 tasks at once!), without the\npatch it was stuck for a minute at times.\n\nThere\u0027s another nice side-effect of this speedup patch, the new generic\nsemaphore code got even smaller:\n\n text data bss dec hex filename\n 1241 0 0 1241 4d9 semaphore.o.before\n 1207 0 0 1207 4b7 semaphore.o.after\n\n(because the waiter.up complication got removed.)\n\nLonger-term we should look into using the mutex code for the generic\nsemaphore code as well - but i\u0027s not easy due to legacies and it\u0027s\noutside of the scope of v2.6.26 and outside the scope of this patch as\nwell.\n\nBisected-by: \"Zhang, Yanmin\" \u003cyanmin_zhang@linux.intel.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "75065ff619e42fe35178eda863cbcddd57776794", "tree": "e41d6e838cb2d2fcd62e5ea1980f720e98b57de7", "parents": [ "ffee0259c9edcc4c0f06b60df51c461eeecad4c0" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Thu May 08 14:06:19 2008 +0200" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Thu May 08 14:06:19 2008 +0200" }, "message": "Revert \"relay: fix splice problem\"\n\nThis reverts commit c3270e577c18b3d0e984c3371493205a4807db9d.\n" }, { "commit": "e3a2efa67a029453b8098dba179ec2d9d8df612e", "tree": "8b5587d7268919a807aa1210ab3b9f10afeeb330", "parents": [ "30a717f7e951ec0260f31c0637ecf8e6268ba607" ], "author": { "name": "Patrik Sevallius", "email": "patrik.sevallius@enea.com", "time": "Thu May 08 14:04:08 2008 +0200" }, "committer": { "name": "Takashi Iwai", "email": "tiwai@suse.de", "time": "Thu May 08 13:08:58 2008 +0200" }, "message": "[ALSA] soc at91 minor bug fixes\n\nFound these two bugs while browsing through the code.

Sometimes it\nwas impossible to deliver a signal to a spinning guest. We used\npreemption as a circumvention. The preemption notifiers called\nvcpu_load, which checked for pending signals and triggered a host\nintercept. But even with preemption, a sigkill was not delivered\nimmediately.\n\nThis patch changes the low level host interrupt handler to check for the\nSIE instruction, if TIF_WORK is set. In that case we change the\ninstruction pointer of the return PSW to rerun the vcpu_run loop. The kvm\ncode sees an intercept reason 0 if that happens.

For example, a 64\nMB registration will require 128 KB of contiguous memory with 4 KB\npages, and it unlikely that such an allocation will succeed on a busy\nsystem.\n\nThis is purely a driver problem: the temporary page list buffer is not\nneeded by the hardware, so we can fix this by writing the PBL to the\nhardware in page-sized chunks rather than all at once. We do this by\nsplitting the memory registration operation up into several steps:\n\n - Allocate PBL space in adapter memory for the full registration\n - Copy PBL to adapter memory in chunks\n - Allocate STag and enable memory region\n\nThis also allows several other cleanups to the __cxio_tpt_op()\ninterface and related parts of the driver.\n\nThis change leaves the reregister memory region and memory window\noperations broken, but they already didn\u0027t work due to other\nlongstanding bugs, so fixing them will be left to a later patch.\n\nSigned-off-by: Roland Dreier \u003crolandd@cisco.com\u003e\n" }, { "commit": "d45100f7b69e3d9cd0cd5e956b6ac2c78d460d07", "tree": "9bf891a3426b68c7deb251f0488881be1b33ad63", "parents": [ "3eb6753e20af1803d7784efc36e8208e8d5fac05" ], "author": { "name": "David S.
