In fact, as far as -\u003endo_get_stats\nis concerned, these values are set completely asynchronously.\n\nFlavio attempted to fix this using a RW semaphore, which in fact\nworks most of the time. However, dev_get_stats() can be invoked\nfrom non-sleepable contexts in some cases, so this fix doesn\u0027t\nwork in all cases.\n\nSo instead, control the visibility of the np-\u003e{rx,tx}_ring pointers\nwhen the device is being brough up, and use properties of the device\ndown sequence to our advantage.\n\nIn niu_get_stats(), return immediately if netif_running() is false.\nThe device shutdown sequence first marks the device as not running (by\nclearing the __LINK_STATE_START bit), then it performans a\nsynchronize_rcu() (in dev_deactive_many()), and then finally it\ninvokes the driver -\u003endo_stop() method.\n\nThis guarentees that all invocations of niu_get_stats() either see\nnetif_running() as false, or they see the channel pointers before\n-\u003endo_stop() clears them out.\n\nIf netif_running() is true, protect against startup races by loading\nthe np-\u003e{rx,tx}_rings pointer into a local variable, and punting if\nit is NULL. Use ACCESS_ONCE to prevent the compiler from reloading\nthe pointer on us.\n\nAlso, during open, control the order in which the pointers and the\nring counts become visible globally using SMP write memory barriers.\nWe make sure the np-\u003enum_{rx,tx}_rings value is stable and visible\nbefore np-\u003e{rx,tx}_rings is.\n\nSuch visibility control is not necessary on the niu_free_channels()\nside because of the RCU sequencing that happens during device down as\ndescribed above. We are always guarenteed that all niu_get_stats\ncalls are finished, or will see netif_running() false, by the time\n-\u003endo_stop is invoked.\n\nReported-by: Flavio Leitner \u003cfleitner@redhat.com\u003e\nSigned-off-by: David S.

with pointer array\n\nCurrently the syscall_meta structures for the syscall tracepoints are\nplaced in the __syscall_metadata section, and at link time, the linker\nmakes one large array of all these syscall metadata structures. On boot\nup, this array is read (much like the initcall sections) and the syscall\ndata is processed.\n\nThe problem is that there is no guarantee that gcc will place complex\nstructures nicely together in an array format. Two structures in the\nsame file may be placed awkwardly, because gcc has no clue that they\nare suppose to be in an array.\n\nA hack was used previous to force the alignment to 4, to pack the\nstructures together. But this caused alignment issues with other\narchitectures (sparc).\n\nInstead of packing the structures into an array, the structures\u0027 addresses\nare now put into the __syscall_metadata section. As pointers are always the\nnatural alignment, gcc should always pack them tightly together\n(otherwise initcall, extable, etc would also fail).\n\nBy having the pointers to the structures in the section, we can still\niterate the trace_events without causing unnecessary alignment problems\nwith other architectures, or depending on the current behaviour of\ngcc that will likely change in the future just to tick us kernel developers\noff a little more.\n\nThe __syscall_metadata section is also moved into the .init.data section\nas it is now only needed at boot up.\n\nSuggested-by: David Miller \u003cdavem@davemloft.net\u003e\nAcked-by: David S.

Implement an approach proposed by David Miller:\nuse an array of const pointers to refer to the individual structures, and export\nthis pointer array through the linker script rather than the structures per se.\nIt will consume 32 extra bytes per tracepoint (24 for structure padding and 8\nfor the pointers), but are less likely to break due to compiler changes.\n\nHistory:\n\ncommit 7e066fb8 tracepoints: add DECLARE_TRACE() and DEFINE_TRACE()\nadded the aligned(32) type and variable attribute to the tracepoint structures\nto deal with gcc happily aligning statically defined structures on 32-byte\nmultiples.\n\nOne attempt was to use a 8-byte alignment for tracepoint structures by applying\nboth the variable and type attribute to tracepoint structures definitions and\ndeclarations. It worked fine with gcc 4.5.1, but broke with gcc 4.4.4 and 4.4.5.\n\nThe reason is that the \"aligned\" attribute only specify the _minimum_ alignment\nfor a structure, leaving both the compiler and the linker free to align on\nlarger multiples. Because tracepoint.c expects the structures to be placed as an\narray within each section, up-alignment cause NULL-pointer exceptions due to the\nextra unexpected padding.\n\n(this patch applies on top of -tip)\n\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nAcked-by: David S.

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": "e4a9ea5ee7c8812a7bf0c3fb725ceeaa3d4c2fcc", "tree": "1b25668508fa302a6ada053c895cd55727f798f1", "parents": [ "9ffdc6c37df131f89d52001e0ef03091b158826f" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Thu Jan 27 09:15:30 2011 -0500" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Wed Feb 02 21:37:13 2011 -0500" }, "message": "tracing: Replace trace_event struct array with pointer array\n\nCurrently the trace_event structures are placed in the _ftrace_events\nsection, and at link time, the linker makes one large array of all\nthe trace_event structures.
