      tracing/events: add support for modules to TRACE_EVENT · 6d723736
      Steven Rostedt authored
      Impact: allow modules to add TRACE_EVENTS on load
      This patch adds the final hooks to allow modules to use the TRACE_EVENT
      macro. A notifier and a data structure are used to link the TRACE_EVENTs
      defined in the module to connect them with the ftrace event tracing system.
      It also adds the necessary automated clean ups to the trace events when a
      module is removed.

      tracing/events: add export symbols for trace events in modules · 17c873ec
      Steven Rostedt authored
      Impact: let modules add trace events
      The trace event code requires some functions to be exported to allow
      modules to use TRACE_EVENT. This patch adds EXPORT_SYMBOL_GPL to the
      necessary functions.

      tracing/events: convert event call sites to use a link list · a59fd602
      Steven Rostedt authored
      Impact: makes it possible to define events in modules
      The events are created by reading down the section that they are linked
      in by the macros. But this is not scalable to modules. This patch converts
      the manipulations to use a global link list, and on boot up it adds
      the items in the section to the list.
      This change will allow modules to add their tracing events to the list as
      Note, this change alone does not permit modules to use the TRACE_EVENT macros,
      but the change is needed for them to eventually do so.

      This patch moves the ftrace creation into include/trace/ftrace.h and
      simplifies the work of developers in adding new tracepoints.
      Just the act of creating the trace points in include/trace and including

      tracing: make trace_seq operations available for core kernel · 9504504c
      Steven Rostedt authored
      In the process to make TRACE_EVENT macro work for modules, the trace_seq
      operations must be available for core kernel code.
      These operations are quite useful and can be used for other implementations.
      The main idea is that we create a trace_seq handle that acts very much
      like the seq_file handle.
      	struct trace_seq *s = kmalloc(sizeof(*s, GFP_KERNEL);
      	trace_seq_printf(s, "some data %d\n", variable);
      	printk("%s", s->buffer);
      The main use is to allow a top level function call several other functions
      that may store printf like data into the buffer. Then at the end, the top
      level function can process all the data with any method it would like to.
      It could be passed to userspace, output via printk or even use seq_file:
      	trace_seq_to_user(s, ubuf, cnt);
      	seq_puts(m, s->buffer);

      tracing: create automated trace defines · a8d154b0
      Steven Rostedt authored
      This patch lowers the number of places a developer must modify to add
      new tracepoints. The current method to add a new tracepoint
      into an existing system is to write the trace point macro in the
      trace header with one of the macros TRACE_EVENT, TRACE_FORMAT or
      DECLARE_TRACE, then they must add the same named item into the C file
      with the macro DEFINE_TRACE(name) and then add the trace point.
      This change cuts out the needing to add the DEFINE_TRACE(name).
      Every file that uses the tracepoint must still include the trace/<type>.h
      file, but the one C file must also add a define before the including
      of that file.
       #define CREATE_TRACE_POINTS
       #include <trace/mytrace.h>
      This will cause the trace/mytrace.h file to also produce the C code
      necessary to implement the trace point.
      Note, if more than one trace/<type>.h is used to create the C code
      it is best to list them all together.
       #define CREATE_TRACE_POINTS
       #include <trace/foo.h>
       #include <trace/bar.h>
       #include <trace/fido.h>
      Thanks to Mathieu Desnoyers and Christoph Hellwig for coming up with
      the cleaner solution of the define above the includes over my first
      design to have the C code include a "special" header.

      tracing: consolidate trace and trace_event headers · ea20d929
      Steven Rostedt authored
      Impact: clean up
      Neil Horman (et. al.) criticized the way the trace events were broken up
      into two files. The reason for that was that ftrace needed to separate out
      the declarations from where the #include <linux/tracepoint.h> was used.
      It then dawned on me that the tracepoint.h header only needs to define the
      TRACE_EVENT macro if it is not already defined.
      The solution is simply to test if TRACE_EVENT is defined, and if it is not
      then the linux/tracepoint.h header can define it. This change consolidates
      all the <traces>.h and <traces>_event_types.h into the <traces>.h file.

      tracing/filters: allow on-the-fly filter switching · 0a19e53c
      Tom Zanussi authored
      This patch allows event filters to be safely removed or switched
      on-the-fly while avoiding the use of rcu or the suspension of tracing of
      previous versions.
      It does it by adding a new filter_pred_none() predicate function which
      does nothing and by never deallocating either the predicates or any of
      the filter_pred members used in matching; the predicate lists are
      allocated and initialized during ftrace_event_calls initialization.
      Whenever a filter is removed or replaced, the filter_pred_* functions
      currently in use by the affected ftrace_event_call are immediately
      switched over to to the filter_pred_none() function, while the rest of
      the filter_pred members are left intact, allowing any currently
      executing filter_pred_* functions to finish up, using the values they're
      currently using.
      In the case of filter replacement, the new predicate values are copied
      into the old predicates after the above step, and the filter_pred_none()
      functions are replaced by the filter_pred_* functions for the new
      filter.  In this case, it is possible though very unlikely that a
      previous filter_pred_* is still running even after the
      filter_pred_none() switch and the switch to the new filter_pred_*.  In
      that case, however, because nothing has been deallocated in the
      filter_pred, the worst that can happen is that the old filter_pred_*
      function sees the new values and as a result produces either a false
      positive or a false negative, depending on the values it finds.
      So one downside to this method is that rarely, it can produce a bad
      match during the filter switch, but it should be possible to live with
      that, IMHO.
      The other downside is that at least in this patch the predicate lists
      are always pre-allocated, taking up memory from the start.  They could
      probably be allocated on first-use, and de-allocated when tracing is
      completely stopped - if this patch makes sense, I could create another
      one to do that later on.
      Oh, and it also places a restriction on the size of __arrays in events,
      currently set to 128, since they can't be larger than the now embedded
      str_val arrays in the filter_pred struct.

      tracing/infrastructure: separate event tracer from event support · 5f77a88b
      Tom Zanussi authored
      Add a new config option, CONFIG_EVENT_TRACING that gets selected
      when CONFIG_TRACING is selected and adds everything needed by the stuff
      in trace_export - basically all the event tracing support needed by e.g.
      bprint, minus the actual events, which are only included if
      CONFIG_EVENT_TRACER is selected.
      So CONFIG_EVENT_TRACER can be used to turn on or off the generated events
      (what I think of as the 'event tracer'), while CONFIG_EVENT_TRACING turns
      on or off the base event tracing support used by both the event tracer and
      the other things such as bprint that can't be configured out.

      ring-buffer: add ring_buffer_discard_commit · fa1b47dd
      Steven Rostedt authored
      The ring_buffer_discard_commit is similar to ring_buffer_event_discard
      but it can only be done on an event that has yet to be commited.
      Unpredictable results can happen otherwise.
      The main difference between ring_buffer_discard_commit and
      ring_buffer_event_discard is that ring_buffer_discard_commit will try
      to free the data in the ring buffer if nothing has addded data
      after the reserved event. If something did, then it acts almost the
      same as ring_buffer_event_discard followed by a
      Note, either ring_buffer_commit_discard and ring_buffer_unlock_commit
      can be called on an event, not both.
      This commit also exports both discard functions to be usable by
      GPL modules.

      tracing/filters: add run-time field descriptions to TRACE_EVENT_FORMAT events · e1112b4d
      Tom Zanussi authored
      This patch adds run-time field descriptions to all the event formats
      exported using TRACE_EVENT_FORMAT.  It also hooks up all the tracers
      that use them (i.e. the tracers in the 'ftrace subsystem') so they can
      also have their output filtered by the event-filtering mechanism.
      When I was testing this, there were a couple of things that fooled me
      into thinking the filters weren't working, when actually they were -
      I'll mention them here so others don't make the same mistakes (and file
      bug reports. ;-)
      One is that some of the tracers trace multiple events e.g. the
      sched_switch tracer uses the context_switch and wakeup events, and if
      you don't set filters on all of the traced events, the unfiltered output
      from the events without filters on them can make it look like the
      filtering as a whole isn't working properly, when actually it is doing
      what it was asked to do - it just wasn't asked to do the right thing.
      The other is that for the really high-volume tracers e.g. the function
      tracer, the volume of filtered events can be so high that it pushes the
      unfiltered events out of the ring buffer before they can be read so e.g.
      cat'ing the trace file repeatedly shows either no output, or once in
      awhile some output but that isn't there the next time you read the
      trace, which isn't what you normally expect when reading the trace file.
      If you read from the trace_pipe file though, you can catch them before
      they disappear.
      Changes from v1:
      As suggested by Frederic Weisbecker:
      - get rid of externs in functions
      - added unlikely() to filter_check_discard()

      In addition, if the resume from hibernation is userland-driven, it's
      better to wait for all device probes in the kernel to complete before
      attempting to open the resume device.

            work_on_cpu(): rewrite it to create a kernel thread on demand
      It seems that the kernel calls these acpi-cpufreq functions at a quite
      high frequency.
      Valdis Kletnieks also reports that this causes 70-90 forks per second on
      his hardware.

      add some long-missing capabilities to fs_mask · 0ad30b8f
      Serge E. Hallyn authored
      When POSIX capabilities were introduced during the 2.1 Linux
      cycle, the fs mask, which represents the capabilities which having
      fsuid==0 is supposed to grant, did not include CAP_MKNOD and
      CAP_LINUX_IMMUTABLE.  However, before capabilities the privilege
      to call these did in fact depend upon fsuid==0.
      This patch introduces those capabilities into the fsmask,
      restoring the old behavior.
      See the thread starting at http://lkml.org/lkml/2009/3/11/157 for
      Note that if this fix is deemed valid, then earlier kernel versions (2.4
      and 2.2) ought to be fixed too.
      	[Mar 23] Actually delete old CAP_FS_SET definition...
      	[Mar 20] Updated against J. Bruce Fields's patch

      i2c: Let new-style drivers implement attach_adapter · 93529869
      Jean Delvare authored
      While it isn't the way the standard device binding model works, it is
      OK for new-style drivers to implement attach_adapter. It may help
      convert the renaming legacy drivers to new style drivers faster.

      i2c: Fix sparse warnings for I2C_BOARD_INFO() · c758e8cf
      Ben Hutchings authored
      Since the first argument to I2C_BOARD_INFO() must be a string constant,
      there is no need to parenthesise it, and adding parentheses results in
      an invalid initialiser for char[].  gcc obviously accepts this syntax as
      an extension, but sparse complains, e.g.:
      drivers/net/sfc/boards.c:173:2: warning: array initialized from parenthesized string constant
      Therefore, remove the parentheses.
