This resulted in the boot\nprocessor reprogramming its MTRR\u0027s to the values seen during the\nstart of the OS boot. While this is not needed ideally, this\nshouldn\u0027t have caused any side-effects. This is because the\nreprogramming of MTRR\u0027s (set_mtrr_state() that gets called via\nset_mtrr()) will check if the live register contents are\ndifferent from what is being asked to write and will do the actual\nwrite only if they are different.\n\nBP\u0027s mtrr state is read during the start of the OS boot and\ntypically nothing would have changed when we ask to reprogram it\non BP again because of the above scenario on an UP platform. So\non a normal UP platform no reprogramming of BP MTRR MSR\u0027s\nhappens and all is well.\n\nHowever, on this platform, bios seems to be modifying the fixed\nmtrr range registers between the start of OS boot and when we\ndouble check the live registers for reprogramming BP MTRR\nregisters. And as the live registers are modified, we end up\nreprogramming the MTRR\u0027s to the state seen during the start of\nthe OS boot.\n\nDuring ACPI initialization, something in the bios (probably smi\nhandler?) don\u0027t like this fact and results in a hard lockup.\n\nWe didn\u0027t see this boot hang issue on this platform before the\ncommit d0af9eed5aa91b6b7b5049cae69e5ea956fd85c3, because only\nthe AP\u0027s (if any) will program its MTRR\u0027s to the value that BP\nhad at the start of the OS boot.\n\nFix this issue by checking mtrr_aps_delayed_init before\ncontinuing further in the mtrr_aps_init(). Now, only AP\u0027s (if\nany) will program its MTRR\u0027s to the BP values during boot.\n\nAddresses https://bugzilla.novell.com/show_bug.cgi?id\u003d623393\n\n [ By the way, this behavior of the bios modifying MTRR\u0027s after the start\n of the OS boot is not common and the kernel is not prepared to\n handle this situation well. Irrespective of this issue, during\n suspend/resume, linux kernel will try to reprogram the BP\u0027s MTRR values\n to the values seen during the start of the OS boot. So suspend/resume might\n be already broken on this platform for all linux kernel versions. ]\n\nReported-and-bisected-by: Markus Kohn \u003cjabber@gmx.org\u003e\nTested-by: Markus Kohn \u003cjabber@gmx.org\u003e\nSigned-off-by: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nCc: Thomas Renninger \u003ctrenn@novell.com\u003e\nCc: Rafael Wysocki \u003crjw@novell.com\u003e\nCc: Venkatesh Pallipadi \u003cvenki@google.com\u003e\nCc: stable@kernel.org # [v2.6.32+]\nLKML-Reference: \u003c1296694975.4418.402.camel@sbsiddha-MOBL3.sc.intel.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "d038b12c6d773a4b9f69ca5243773bf6314f7ee9", "tree": "c59c68b0e94c3a84d8ebd8fe48974c616f2ae303", "parents": [ "88d4f0db7fa8785859c1d637f9aac210932b6216" ], "author": { "name": "Stephane Eranian", "email": "eranian@google.com", "time": "Tue Jan 25 17:32:01 2011 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jan 27 19:21:53 2011 +0100" }, "message": "perf: Fix Pentium4 raw event validation\n\nThis patch fixes some issues with raw event validation on\nPentium 4 (Netburst) based processors.\n\nAs I was testing libpfm4 Netburst support, I ran into two\nproblems in the p4_validate_raw_event() function:\n\n - the shared field must be checked ONLY when HT is on\n - the binding to ESCR register was missing\n\nThe second item was causing raw events to not be encoded\ncorrectly compared to generic PMU events.\n\nWith this patch, I can now pass Netburst events to libpfm4\nexamples and get meaningful results:\n\n $ task -e global_power_events:running:u noploop 1\n noploop for 1 seconds\n 3,206,304,898 global_power_events:running\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Cyrill Gorcunov \u003cgorcunov@openvz.org\u003e\nCc: peterz@infradead.org\nCc: paulus@samba.org\nCc: davem@davemloft.net\nCc: fweisbec@gmail.com\nCc: perfmon2-devel@lists.sf.net\nCc: eranian@gmail.com\nCc: robert.richter@amd.com\nCc: acme@redhat.com\nCc: gorcunov@gmail.com\nCc: ming.m.lin@intel.com\nLKML-Reference: \u003c4d3efb2f.1252d80a.1a80.ffffc83f@mx.google.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "2e5aa6824d9e0248d734573dad8858a2cc279cfe", "tree": "535b372f88eee1ac3e56eda16c8618499f34fbaa", "parents": [ "ec30f343d61391ab23705e50a525da1d55395780" ], "author": { "name": "Jesper Juhl", "email": "jj@chaosbits.net", "time": "Mon Jan 24 22:41:11 2011 +0100" }, "committer": { "name": "H.
