Remove an unconditinal\n might_sleep() in the might_fault() inline in kernel.h (used when\n PROVE_LOCKING is not set).\n\n 4.

I even heard that Google was about to implement it themselves.\n I finally had time and cleaned up the code such that you can now\n create multiple instances of the ftrace buffer and have different\n events go to different buffers. This way, a low frequency event will\n not be lost in the noise of a high frequency event.\n\n Note, currently only events can go to different buffers, the tracers\n (ie function, function_graph and the latency tracers) still can only\n be written to the main buffer.\n\n 2) The function tracer triggers have now been extended.\n\n The function tracer had two triggers. One to enable tracing when a\n function is hit, and one to disable tracing. Now you can record a\n stack trace on a single (or many) function(s), take a snapshot of the\n buffer (copy it to the snapshot buffer), and you can enable or disable\n an event to be traced when a function is hit.\n\n 3) A perf clock has been added.\n\n A \"perf\" clock can be chosen to be used when tracing. This will cause\n ftrace to use the same clock as perf uses, and hopefully this will\n make it easier to interleave the perf and ftrace data for analysis.\"\n\n* tag \u0027trace-3.10\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (82 commits)\n tracepoints: Prevent null probe from being added\n tracing: Compare to 1 instead of zero for is_signed_type()\n tracing: Remove obsolete macro guard _TRACE_PROFILE_INIT\n ftrace: Get rid of ftrace_profile_bits\n tracing: Check return value of tracing_init_dentry()\n tracing: Get rid of unneeded key calculation in ftrace_hash_move()\n tracing: Reset ftrace_graph_filter_enabled if count is zero\n tracing: Fix off-by-one on allocating stat-\u003epages\n kernel: tracing: Use strlcpy instead of strncpy\n tracing: Update debugfs README file\n tracing: Fix ftrace_dump()\n tracing: Rename trace_event_mutex to trace_event_sem\n tracing: Fix comment about prefix in arch_syscall_match_sym_name()\n tracing: Convert trace_destroy_fields() to static\n tracing: Move find_event_field() into trace_events.c\n tracing: Use TRACE_MAX_PRINT instead of constant\n tracing: Use pr_warn_once instead of open coded implementation\n ring-buffer: Add ring buffer startup selftest\n tracing: Bring Documentation/trace/ftrace.txt up to date\n tracing: Add \"perf\" trace_clock\n ...\n\nConflicts:\n\tkernel/trace/ftrace.c\n\tkernel/trace/trace.c\n" }, { "commit": "dc72c32e1fd872a9a4fdfe645283c9dcd68e556d", "tree": "66f817ecb840f59173de2a95a9a69fb5c3a75d21", "parents": [ "fe8d52614bd419cedef85ef55850fd090373f481" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Fri Mar 22 15:04:39 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 22 16:41:20 2013 -0700" }, "message": "printk: Provide a wake_up_klogd() off-case\n\nwake_up_klogd() is useless when CONFIG_PRINTK\u003dn because neither printk()\nnor printk_sched() are in use and there are actually no waiter on\nlog_wait waitqueue.

The C standard says \"If one operand has\nunsigned int type, the other operand is converted to unsigned int\", so\nthe compiler is not to blame. As a result, DIV_ROUND_CLOSEST(0, 2U) and\nsimilar operations now return bad values, since the automatic conversion\nof expressions such as \"0 - 2U/2\" to unsigned was not taken into\naccount.\n\nFix by checking for the divisor variable type when deciding which\noperation to perform. This fixes DIV_ROUND_CLOSEST(0, 2U), but still\nreturns bad values for negative dividends divided by unsigned divisors.\nMark the latter case as unsupported.\n\nOne observed effect of this problem is that the s2c_hwmon driver reports\na value of 4198403 instead of 0 if the ADC reads 0.\n\nOther impact is unpredictable.

To\ndo this safely in an SMP environment, a spin_lock() is taken\nto only allow one writer at a time to the buffer. But this could\nalso affect what is being traced, and add synchronization that\nwould not be there otherwise.\n\nIdeally, using percpu buffers would be useful, but since trace_printk()\nis only used in development, having per cpu buffers for something\nnever used is a waste of space. Thus, the use of the trace_bprintk()\nformat section is changed to be used for static fmts as well as dynamic ones.\nThen at boot up, we can check if the section that holds the trace_printk\nformats is non-empty, and if it does contain something, then we\nknow a trace_printk() has been added to the kernel. At this time\nthe trace_printk per cpu buffers are allocated. A check is also\ndone at module load time in case a module is added that contains a\ntrace_printk().\n\nOnce the buffers are allocated, they are never freed.

For example for the \u0027CPU\u0027\n PMU we have:\n\n aldebaran:~\u003e ll /sys/bus/event_source/devices/cpu/format/*\n -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/any\n -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/cmask\n -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/edge\n -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/event\n -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/inv\n -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/offcore_rsp\n -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/pc\n -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/umask\n\n those lists of fields contain a specific format:\n\n aldebaran:~\u003e cat /sys/bus/event_source/devices/cpu/format/offcore_rsp\n config1:0-63\n\n So, those who wish to specify raw events can now use the following\n event format:\n\n -e cpu/cmask\u003d1,event\u003d2,umask\u003d3\n\n Most people will not want to specify any events (let alone raw\n events), they\u0027ll just use whatever default event the tools use.\n\n But for more obscure PMU events that have no cross-architecture\n generic events the above syntax is more usable and a bit more\n structured than specifying hex numbers.\"\n\n* \u0027perf-urgent-for-linus\u0027 of
