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.
