Improves efficiency of\nresched_task and some cpu_idle routines.\n\n* In resched_task:\n- TIF_NEED_RESCHED is only cleared with the task\u0027s runqueue lock held,\n and as we hold it during resched_task, then there is no need for an\n atomic test and set there. The only other time this should be set is\n when the task\u0027s quantum expires, in the timer interrupt - this is\n protected against because the rq lock is irq-safe.\n\n- If TIF_NEED_RESCHED is set, then we don\u0027t need to do anything. It\n won\u0027t get unset until the task get\u0027s schedule()d off.\n\n- If we are running on the same CPU as the task we resched, then set\n TIF_NEED_RESCHED and no further action is required.\n\n- If we are running on another CPU, and TIF_POLLING_NRFLAG is *not* set\n after TIF_NEED_RESCHED has been set, then we need to send an IPI.\n\nUsing these rules, we are able to remove the test and set operation in\nresched_task, and make clear the previously vague semantics of\nPOLLING_NRFLAG.\n\n* In idle routines:\n- Enter cpu_idle with preempt disabled. When the need_resched() condition\n becomes true, explicitly call schedule(). This makes things a bit clearer\n (IMO), but haven\u0027t updated all architectures yet.\n\n- Many do a test and clear of TIF_NEED_RESCHED for some reason. According\n to the resched_task rules, this isn\u0027t needed (and actually breaks the\n assumption that TIF_NEED_RESCHED is only cleared with the runqueue lock\n held). So remove that. Generally one less locked memory op when switching\n to the idle thread.\n\n- Many idle routines clear TIF_POLLING_NRFLAG, and only set it in the inner\n most polling idle loops. The above resched_task semantics allow it to be\n set until before the last time need_resched() is checked before going into\n a halt requiring interrupt wakeup.\n\n Many idle routines simply never enter such a halt, and so POLLING_NRFLAG\n can be always left set, completely eliminating resched IPIs when rescheduling\n the idle task.\n\n POLLING_NRFLAG width can be increased, to reduce the chance of resched IPIs.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Con Kolivas \u003ckernel@kolivas.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5bfb5d690f36d316a5f3b4f7775fda996faa6b12", "tree": "ea53f15293d1ddb49c316eb65df85e939a4f6e5e", "parents": [ "ede3d0fba99520f268067917b50858d788bc41da" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Tue Nov 08 21:39:01 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Nov 09 07:56:33 2005 -0800" }, "message": "[PATCH] sched: disable preempt in idle tasks\n\nRun idle threads with preempt disabled.\n\nAlso corrected a bugs in arm26\u0027s cpu_idle (make it actually call schedule()).\nHow did it ever work before?\n\nMight fix the CPU hotplugging hang which Nigel Cunningham noted.\n\nWe think the bug hits if the idle thread is preempted after checking\nneed_resched() and before going to sleep, then the CPU offlined.\n\nAfter calling stop_machine_run, the CPU eventually returns from preemption and\ninto the idle thread and goes to sleep.

It turns\nout that to be %100 safe we do need to be able to translate\nOBP mappings in our TLB miss handlers early.\n\nIn order not to eat up a lot of kernel image memory with\nstatic page tables, just use the translations array in\nthe OBP TLB miss handlers. That solves the bulk of the\nproblem.\n\nFurthermore, to make sure the OBP TLB miss path will work\neven before the fixed MMU globals are loaded, explicitly\nload %g1 to TLB_SFSR at the beginning of the i-TLB and\nd-TLB miss handlers.\n\nTo ease the OBP TLB miss walking of the prom_trans[] array,\nwe sort it then delete all of the non-OBP entries in there\n(for example, there are entries for the kernel image itself\nwhich we\u0027re not interested in at all).\n\nWe also save about 32K of kernel image size with this change.\nNot a bad side effect :-)\n\nThere are still some reasons why trampoline.S can\u0027t use the\nsetup_trap_table() yet. The most noteworthy are:\n\n1) OBP boots secondary processors with non-bias\u0027d stack for\n some reason. This is easily fixed by using a small bootup\n stack in the kernel image explicitly for this purpose.\n\n2) Doing a firmware call via the normal C call prom_set_trap_table()\n goes through the whole OBP enter/exit sequence that saves and\n restores OBP and Linux kernel state in the MMUs. This path\n unfortunately does a \"flush %g6\" while loading up the OBP locked\n TLB entries for the firmware call.\n\n If we setup the %g6 in the trampoline.S code properly, that\n is in the PAGE_OFFSET linear mapping, but we\u0027re not on the\n kernel trap table yet so those addresses won\u0027t translate properly.\n\n One idea is to do a by-hand firmware call like we do in the\n early bootup code and elsewhere here in trampoline.S But this\n fails as well, as aparently the secondary processors are not\n booted with OBP\u0027s special locked TLB entries loaded.

These resources get linked into the\n iomem/ioport tree when PCI controllers are probed.\n\n So the hierarchy looks like this:\n\n iomem --|\n\t PCI controller 1 MEM space --|\n\t\t\t\t device 1\n\t\t\t\t\tdevice 2\n\t\t\t\t\tetc.\n\t PCI controller 2 MEM space --|\n\t\t\t\t ...\n ioport --|\n PCI controller 1 IO space --|\n\t\t\t\t\t...\n PCI controller 2 IO space --|\n\t\t\t\t\t...\n\n You get the idea. The drivers/pci/setup-res.c code allocates\n using plain iomem_space and ioport_space as the root, so that\n wouldn\u0027t work with the above setup.\n\n So I added a pcibios_select_root() that is used to handle this.\n It uses the PCI controller struct\u0027s io_space and mem_space on\n sparc64, and io{port,mem}_resource on every other platform to\n keep current behavior.\n\n2) quirk_io_region() is buggy. It takes in raw BUS view addresses\n and tries to use them as a PCI resource.\n\n pci_claim_resource() expects the resource to be fully formed when\n it gets called. The sparc64 implementation would do the translation\n but that\u0027s absolutely wrong, because if the same resource gets\n released then re-claimed we\u0027ll adjust things twice.\n\n So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource()\n conversion before passing it on to pci_claim_resource().\n\n3) I was mistakedly __init\u0027ing the function methods the PCI controller\n drivers provide on sparc64 to implement some parts of these\n routines.

This leaves such\na device in an inaccessible state. The patch below causes the BARs\nto be restored when enabling such a device, so that its driver will\nbe able to access it.\n\nThe patch also adds pci_restore_bars as a new global symbol, and adds a\ncorrepsonding EXPORT_SYMBOL_GPL for that.\n\nSome firmware (e.g. Thinkpad T21) leaves devices in D3hot after a\n(re)boot. Most drivers call pci_enable_device very early, so devices\nleft in D3hot that lose configuration during the D3hot-\u003eD0 transition\nwill be inaccessible to their drivers.\n\nDrivers could be modified to account for this, but it would\nbe difficult to know which drivers need modification.
