This could\nlead to potential kernel panic(). This issue is becoming more visible with 2.6\nkernel (as default HZ is 1000) and on platforms with higher SMI handling\nlatencies. During the boot time, SMIs are mostly used by BIOS (for things\nlike legacy keyboard emulation).\n\nDescription:\nThe psuedocode for current delay calibration with tsc based delay looks like\n(0) Estimate a value for loops_per_jiffy\n(1) While (loops_per_jiffy estimate is accurate enough)\n(2) wait for jiffy transition (jiffy1)\n(3) Note down current tsc (tsc1)\n(4) loop until tsc becomes tsc1 + loops_per_jiffy\n(5) check whether jiffy changed since jiffy1 or not and refine\nloops_per_jiffy estimate\n\nConsider the following cases\nCase 1:\nIf SMIs happen between (2) and (3) above, we can end up with a\nloops_per_jiffy value that is too low. This results in shorted delays and\nkernel can panic () during boot (Mostly at IOAPIC timer initialization\ntimer_irq_works() as we don\u0027t have enough timer interrupts in a specified\ninterval).\n\nCase 2:\nIf SMIs happen between (3) and (4) above, then we can end up with a\nloops_per_jiffy value that is too high. And with current i386 code, too\nhigh lpj value (greater than 17M) can result in a overflow in\ndelay.c:__const_udelay() again resulting in shorter delay and panic().\n\nSolution:\nThe patch below makes the calibration routine aware of asynchronous events\nlike SMIs. We increase the delay calibration time and also identify any\nsignificant errors (greater than 12.5%) in the calibration and notify it to\nuser.\n\nPatch below changes both i386 and x86-64 architectures to use this\nnew and improved calibrate_delay_direct() routine.\n\nSigned-off-by: Venkatesh Pallipadi \u003cvenkatesh.pallipadi@intel.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c5d28fb297efaa97c4b90e36f9dff3066e7f2778", "tree": "b0636983104860fa15d9054d29ec9e8b912642cd", "parents": [ "91350ed49bf3613e243c2e216228cd4ae8f32516" ], "author": { "name": "Dave Jones", "email": "davej@redhat.com", "time": "Tue May 31 19:03:46 2005 -0700" }, "committer": { "name": "Dave Jones", "email": "davej@redhat.com", "time": "Tue May 31 19:03:46 2005 -0700" }, "message": "[CPUFREQ] Recalibrate cpu_khz [2/2]\n\nSome cpufreq drivers (at that time, only powernow-k7) need to recalibrate the\ncpu_khz at runtime.\n\nSigned-off-by: Bruno Ducrot \u003cducrot@poupinou.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Dave Jones \u003cdavej@redhat.com\u003e\n\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
