The calibration is based on readout of the PIT/HPET timer to detect the\n wrap of the periodic tick. It happens that a box gets stuck in the\n calibration loop due to a PIT with a broken readout function.\n\n2. CoreDuo boxen show a sporadic PIT runs too slow defect, which results\n in a wrong lapic calibration. The PIT goes back to normal operation once\n the lapic timer is switched to periodic mode.\n\nBoth are existing and unfixed problems in the current upstream kernel and\nprevent certain laptops and other systems from booting Linux.\n\nRework the code to address both problems:\n\n- Make the calibration interrupt driven. This removes the wait_timer_tick\n magic hackery from lapic.c and time_hpet.c. The clockevents framework\n allows easy substitution of the global tick event handler for the\n calibration. This is more accurate than monitoring jiffies. At this point\n of the boot process, nothing disturbes the interrupt delivery, so the\n results are very accurate.\n\n- Verify the calibration against the PM timer, when available by using the\n early access function. When the measured calibration period is outside of\n an one percent window, then the lapic timer calibration is adjusted to the\n pm timer result.\n\n- Verify the calibration by running the lapic timer with the calibration\n handler. Disable lapic timer in case of deviation.\n\nThis also removes the \"synchronization\" of the local apic timer to the global\ntick. This synchronization never worked, as there is no way to synchronize\nPIT(HPET) and local APIC timer. The synchronization by waiting for the tick\njust alignes the local APIC timer for the first events, but later the events\ndrift away due to the different clocks.

It works by taking over the local APIC clock when APIC is\nconfigured, which requires a couple hooks into the APIC code. The backend\ntimer code could be commonized into the timer infrastructure, but there are\nsome pieces missing (stolen time, in particular), and the exact semantics of\nwhen to do accounting for NO_IDLE need to be shared between different\nhypervisors as well. So for now, VMI timer is a separate module.\n\n[Adrian Bunk: cleanups]\n\nSubject: VMI timer patches\nSigned-off-by: Zachary Amsden \u003czach@vmware.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Chris Wright \u003cchrisw@sous-sol.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\n" }, { "commit": "7ce0bcfd1667736f1293cff845139bbee53186de", "tree": "54e70c1e0731d279dfe51efdc06db58d432575ff", "parents": [ "ae5da273fe3352febd38658d8d34484cbcfb3423" ], "author": { "name": "Zachary Amsden", "email": "zach@vmware.com", "time": "Tue Feb 13 13:26:21 2007 +0100" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Tue Feb 13 13:26:21 2007 +0100" }, "message": "[PATCH] i386: vMI backend for paravirt-ops\n\nFairly straightforward implementation of VMI backend for paravirt-ops.\n\n[Adrian Bunk: some cleanups]\n\nSigned-off-by: Zachary Amsden \u003czach@vmware.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Chris Wright \u003cchrisw@sous-sol.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\n" }, { "commit": "ae5da273fe3352febd38658d8d34484cbcfb3423", "tree": "70f619e6c0195bd2684b897d37bde37daa865c86", "parents": [ "8b15114434998a78aa50f8559d69c7a400cff267" ], "author": { "name": "Zachary Amsden", "email": "zach@vmware.com", "time": "Tue Feb 13 13:26:21 2007 +0100" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Tue Feb 13 13:26:21 2007 +0100" }, "message": "[PATCH] i386: SMP boot hook for paravirt\n\nAdd VMI SMP boot hook.

Unfortunately there\nare two SMP-related problems with this approach. First, a task running on\nanother CPU may be updating its flags while the freezer attempts to set\nPF_FREEZE for it and this may leave the task\u0027s flags in an inconsistent\nstate. Second, there is a potential race between freeze_process() and\nrefrigerator() in which freeze_process() running on one CPU is reading a\ntask\u0027s PF_FREEZE flag while refrigerator() running on another CPU has just\nset PF_FROZEN for the same task and attempts to reset PF_FREEZE for it. If\nthe refrigerator wins the race, freeze_process() will state that PF_FREEZE\nhasn\u0027t been set for the task and will set it unnecessarily, so the task\nwill go to the refrigerator once again after it\u0027s been thawed.\n\nTo solve first of these problems we need to stop using PF_FREEZE to tell\ntasks that they should go to the refrigerator. Instead, we can introduce a\nspecial TIF_*** flag and use it for this purpose, since it is allowed to\nchange the other tasks\u0027 TIF_*** flags and there are special calls for it.\n\nTo avoid the freeze_process()-refrigerator() race we can make\nfreeze_process() to always check the task\u0027s PF_FROZEN flag after it\u0027s read\nits \"freeze\" flag. We should also make sure that refrigerator() will\nalways reset the task\u0027s \"freeze\" flag after it\u0027s set PF_FROZEN for it.\n\nSigned-off-by: Rafael J.
