The data collected during +a counting session is displayed to stdout by default or, optionally, +to a file. +.P +When counting multiple events, the kernel may not be able to count all events +simultaneously and, thus, may need to multiplex the counting of the events. +If this happens, the "Percent time enabled" column in the +.B ocount +output will be less than 100, but counts are scaled up to a 100% estimated value. +.br + +.SH RUN MODES +One (and only one) of the following +.SB run modes +must be specified.

-This manual applies to OProfile version 0.9.8. -OProfile is a profiling system for Linux 2.6 and higher systems on a number of architectures. It is capable of profiling -all parts of a running system, from the kernel (including modules and interrupt handlers) to shared libraries -to binaries. OProfile can profile the whole system in the background, collecting information at a low overhead. These -features make it ideal for profiling entire systems to determine bottle necks in real-world systems. +This manual applies to OProfile version 1.0.0. +OProfile is a set of performance monitoring tools for Linux 2.6 and higher systems, available on a number of architectures. +OProfile provides the following features: +

+
+
    +
  • Profiler
    • +
  • Post-processing tools for analyzing profile data
    • +
  • Event counter
    • +
+
+

+

+

+OProfile is capable of monitoring native hardware events occurring in all parts of a running system, from the kernel +(including modules and interrupt handlers) to shared libraries +to binaries. OProfile can collect event information for the whole system in the background with very little overhead. These +features make it ideal for monitoring entire systems to determine bottle necks in real-world systems.

Many CPUs provide "performance counters", hardware registers that can count "events"; for example, -cache misses, or CPU cycles. OProfile provides profiles of code based on the number of these occurring events: +cache misses, or CPU cycles. OProfile can collect profiles of code based on the number of these occurring events: repeatedly, every time a certain (configurable) number of events has occurred, the PC value is recorded. -This information is aggregated into profiles for each binary image.

-

-Some hardware setups do not allow OProfile to use performance counters: in these cases, no -events are available so OProfile operates in timer mode, as described in later chapters. Timer -mode is only available in "legacy mode" (see Section 1, “OProfile legacy mode”). -

-

1. OProfile legacy mode

-"Legacy" OProfile consists of the opcontrol shell script, the oprofiled daemon, and several post-processing tools (e.g., -opreport). The opcontrol script is used for configuring, starting, and stopping a profiling session. An OProfile -kernel driver (usually built as a kernel module) is used for collecting samples, which are then recorded into sample files by -oprofiled. Using OProfile in "legacy mode" requires root user authority since the profiling is done on a system-wide basis, which may -(if misused) cause adverse effects to the system. -

Note

-Profiling setup parameters that you specify using opcontrol are cached in /root/.oprofile/daemonrc. -Subsequent runs of opcontrol --start will continue to use these cached values until you -override them with new values. -
-

2. OProfile perf_events mode

-As of release 0.9.8, OProfile now includes the ability to profile a single process versus the system-wide technique -of legacy OProfile. With this new technique, the operf program is used to control profiling instead of the -opcontrol script and oprofiled daemon of leagacy mode. Also, operf does not require the -special OProfile kernel driver that legacy mode does; instead, it interfaces with the kernel to collect samples via the Linux Kernel -Performance Events Subsystem (hereafter referred to as "perf_events"). Using operf to profile a single -process can be done as a normal user; however, root authority is required to run operf in system-wide -profiling mode. -

Note 1

-The same OProfile post-processing tools are used whether you collect your profile with operf or opcontrol. -

Note 2

+This information is aggregated into profiles for each binary image. Alternatively, OProfile's event counting +tool can collect simple raw event counts.

+

1. OProfile legacy profiling mode

+Prior to release 1.0, OProfile included a profiling tool consisting of the opcontrol shell script, the oprofiled daemon, +and the attendant oprofile kernel driver. This "legacy profiler" was deprecated in release 0.9.8 with the introduction of +the operf profiling tool (see Section 2, “OProfile perf_events profiling mode”). Some older architectures/platforms +do not support the use of operf. For those cases, oprofile users should install release 0.9.9, which is the +last release to include the legacy profiler. +
+
+
+
+
+

2. OProfile perf_events profiling mode

+
+
+
+

+OProfile has the ability to profile a single process or every currently running process (i.e., system-wide) +via the operf program. operf interfaces with the +kernel to collect samples via the Linux Kernel Performance Events Subsystem (hereafter +referred to as "perf_events"). OProfile can co-exist with other tools on your system that +may also be using the perf_events kernel subsystem. +

+

+Using operf to profile a single +process can be done as a normal user; however, root authority is required to run +operf in system-wide profiling mode. +

+

Note

Some older processor models are not supported by the underlying perf_events kernel and, thus, are not supported by operf. If you receive the message 
  Your kernel's Performance Events Subsystem does not support your processor type
-when attempting to use operf, try profiling with opcontrol +when attempting to use operf, install OProfile 0.9.9 and try profiling with opcontrol to see if your processor type may be supported by OProfile's legacy mode. -
-
+
+

+

+
+

3. OProfile event counting mode

+OProfile provides the ocount tool for +collecting raw event counts on a per-application, per-process, per-cpu, or system-wide basis. Unlike the +profiling tools, post-processing of the data collected is not necessary -- the data is displayed in the +output of ocount. A common use case for event counting tools is when performance analysts +want to determine the CPI (cycles per instruction) for an application. High CPI implies possible stalls, +and many architectures provide events that give detailed information about the different types of stalls. +The events provided are architecture-specific, so we refer the reader to the hardware manuals available for +the processor type being used. +

    -Before you can use OProfile's legacy mode, you must set it up. The minimum setup required for this -is to tell OProfile where the vmlinux file corresponding to the -running kernel is, for example : +ocount is an OProfile tool that can be used to count native hardware events occurring in either +a specific application, a set of processes or threads, a set of active system processors, or the +entire system. The data collected during a counting session is displayed to stdout by default, but may +also be saved to a file. The ocount syntax is as follows:

    -

    + 
    ocount [ options ] [ --system-wide | --process-list <pids> | --thread-list <tids> | --cpu-list <cpus> [ command [ args ] ] ]

    -Now we are ready to start the daemon (oprofiled) which collects -the profile data :

    -Note that unlike gprof, no instrumentation (-pg -and -a options to gcc) -is necessary.

    -Periodically (or on opcontrol --shutdown or opcontrol --dump) -the profile data is written out into the $SESSION_DIR/samples directory (by default at /var/lib/oprofile/samples). -These profile files cover shared libraries, applications, the kernel (vmlinux), and kernel modules. -You can clear the profile data (at any time) with opcontrol --reset. +When my_test_program completes (or when you press Ctrl-C), counting +stops and the results are displayed to the screen (as shown below).

See Section 1, “Using operf” for an -introduction to hardware events and performance counter configuration. -The event types and unit masks for your CPU are listed by opcontrol ---list-events or ophelp. -

    -

    -The opcontrol script provides the following actions : -

    -
    -
    -
    - - --init - -
    -
    -

    - Loads the OProfile module if required and makes the OProfile driver - interface available. -

    -
    -
    - - --setup - -
    -
    -

    - Followed by list arguments for profiling set up. List of arguments - saved in /root/.oprofile/daemonrc. - Giving this option is not necessary; you can just directly pass one - of the setup options, e.g. opcontrol --no-vmlinux. -

    -
    - --separate=[none,lib,kernel,thread,cpu,all] -
    -
    -

    - By default, every profile is stored in a single file. Thus, for example, - samples in the C library are all accredited to the /lib/libc.o - profile. However, you choose to create separate sample files by specifying - one of the below options. -

    -
    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    - none - No profile separation (default)
    - lib - Create per-application profiles for libraries

    - thread - Create profiles for each thread and each task
    - cpu - Create profiles for each CPU
    - all - All of the above options
    -
    -

    - Note that --separate=kernel also turns on --separate=lib. - - When using --separate=kernel, samples in hardware interrupts, soft-irqs, or other - asynchronous kernel contexts are credited to the task currently running. This means you will see - seemingly nonsense profiles such as /bin/bash showing samples for the PPP modules, - etc. -

    -

    - Using --separate=thread creates a lot - of sample files if you leave OProfile running for a while; it's most - useful when used for short sessions, or when using image filtering. -

    - --image=image,[images]|"all" -
    -
    -

    - Image filtering. If you specify one or more absolute - paths to binaries, OProfile will only produce profile results for those - binary images. This is useful for restricting the sometimes voluminous - output you may get otherwise, especially with - --separate=thread. Note that if you are using - --separate=lib or - --separate=kernel, then if you specification an - application binary, the shared libraries and kernel code - are included. Specify the value - "all" to profile everything (the default). -

    -
    -

    - Use this when you don't have a kernel vmlinux file, and you don't want - to profile the kernel. This still counts the total number of kernel samples, - but can't give symbol-based results for the kernel or any modules. -

    -
    -

    -Here, we have a Pentium III running at 800MHz, and we want to look at where data memory -references are happening most, and also get results for CPU time. -

    -It can often be useful to split up profiling data into several different -time periods. For example, you may want to collect data on an application's -startup separately from the normal runtime data. You can use the simple -command opcontrol --save to do this. For example : -

    - - - - -
    - 
    -# opcontrol --save=blah
-
    -
    -

    -will create a sub-directory in $SESSION_DIR/samples containing the samples -up to that point (the current session's sample files are moved into this -directory). You can then pass this session name as a parameter to the post-profiling -analysis tools, to only get data up to the point you named the -session. If you do not want to save a session, you can do -rm -rf $SESSION_DIR/samples/sessionname or, for the -current session, opcontrol --reset. -

    3. Specifying performance counter events

    -
    -
    -
    -

    -Both methods of profiling (operf and opcontrol) -allow you to give one or more event specifications to provide details of how each -hardware performance counter should be setup. With operf, you -can provide a comma-separated list of event specfications using the --events -option. With opcontrol, you use the --event option -for each desired event specification. -The event specification is a colon-separated string of the form -name:count:unitmask:kernel:user -as described in the table below. -

    -

    -If no event specs are passed to operf or opcontrol, -the default event will be used for profiling. With opcontrol, if you have -previously specified some non-default event but want to revert to the default event, use ---event=default. Use of this option overrides all previous event selections -that have been cached. -

    -

    -

    -

    Note

    OProfile will allocate hardware counters as necessary, but some processor -types have restrictions as to what hardware events may be counted simultaneously. -The operf program uses a multiplexing technique when such -hardware restrictions are encountered, but opcontrol does -not have this capability; instead, opcontrol will display an -error message if you select an incompatible set of events. -
    -

    -

    -
    - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    - name - The symbolic event name, e.g. CPU_CLK_UNHALTED
    - count - The counter reset value, e.g. 100000
    - unitmask - The unit mask, as given in the events list: e.g. 0x0f; or a symbolic name as -given by the first word of the description (only valid for unit masks having an "extra:" parameter)
    - kernel - Whether to profile kernel code
    - user - Whether to profile userspace code
    -
    -

    -The last three values are optional, if you omit them (e.g. --event=DATA_MEM_REFS:30000), -they will be set to the default values (a unit mask of 0, and profiling both kernel and -userspace code). Note that some events require a unit mask. -

    -

    -When specifying a unit mask value, it may be either a hexadecimal value (which -must begin with "0x") or a string (i.e, symbolic name) which matches -the first word in the unit mask description. Specifying a symbolic name for -the unit mask is valid only for unit masks having "extra:" parameters, as -shown by the output of ophelp. Unit masks with "extra:" parameters must be -specified using the symbolic name. -

    -
    -

    Note

    -

    -When using legacy mode opcontrol on PowerPC platforms, all events specified must be in the same group; -i.e., the group number appended to the event name (e.g. <some-event-name>_GRP9 -) must be the same. -

    -
    -

    -If OProfile is using timer-interrupt mode, there is no event configuration possible. -

    -To profile an SPU application, the user should specify the SPU_CYCLES event. -When starting OProfile with SPU_CYCLES, the opcontrol script enforces certain -separation parameters (separate=cpu,lib) to ensure that sufficient information -is collected in the sample data in order to generate a complete report. The ---merge=cpu option can be used to obtain a more readable report if analyzing -the performance of each separate SPU is not necessary. -

    -

    -Profiling with an SPU event (events 4100 through 4163) is not compatible with any other -event. Further more, only one SPU event can be specified at a time. The hardware only -supports profiling on one SPU per node at a time. The OProfile kernel code time slices -between the eight SPUs to collect data on all SPUs. -

    -

    -SPU profile reports have some unique characteristics compared to reports for -standard architectures: -

    -
    -
      -
    • Typically no "app name" column. This is really standard OProfile behavior -when the report contains samples for just a single application, which is -commonly the case when profiling SPUs.
      • -
    • "CPU" equates to "SPU"
      • -
    • Specifying '--long-filenames' on the opreport command does not always result -in long filenames. This happens when the SPU application code is embedded in -the PPE executable or shared library. The embedded SPU ELF data contains only the -short filename (i.e., no path information) for the SPU binary file that was used as -the source for embedding. The reason that just the short filename is used is because -the original SPU binary file may not exist or be accessible at runtime. The performance -analyst must have sufficient knowledge of the application to be able to correlate the -SPU binary image names found in the report to the application's source files. -

      Note

      -Compile the application with -g and generate the OProfile report -with -g to facilitate finding the right source file(s) on which to focus. -

    6.7. AMD64 (x86_64) Instruction-Based Sampling (IBS) support

    -
    -
    -
    -

    -Instruction-Based Sampling (IBS) is a new performance measurement technique -available on AMD Family 10h processors. Traditional performance counter -sampling is not precise enough to isolate performance issues to individual -instructions. IBS, however, precisely identifies instructions which are not -making the best use of the processor pipeline and memory hierarchy. -For more information, please refer to the "Instruction-Based Sampling: -A New Performance Analysis Technique for AMD Family 10h Processors" ( - -http://developer.amd.com/assets/AMD_IBS_paper_EN.pdf). -There are two types of IBS profile types, described in the following sections. -

    -

    Note

    Profiling on IBS events is only supported with legacy mode profiling -(i.e., with opcontrol).
    -

    6.7.1. IBS Fetch

    -
    -
    -
    -

    -IBS fetch sampling is a statistical sampling method which counts completed -fetch operations. When the number of completed fetch operations reaches the -maximum fetch count (the sampling period), IBS tags the fetch operation and -monitors that operation until it either completes or aborts. When a tagged -fetch completes or aborts, a sampling interrupt is generated and an IBS fetch -sample is taken. An IBS fetch sample contains a timestamp, the identifier of -the interrupted process, the virtual fetch address, and several event flags -and values that describe what happened during the fetch operation.

    -
    +
    -

    6.7.2. IBS Op

    +

    3.3.2. PowerPC64 support

    -IBS op sampling selects, tags, and monitors macro-ops as issued from AMD64 -instructions. Two options are available for selecting ops for sampling: -

    -
    -
      -
    • -Cycles-based selection counts CPU clock cycles. The op is tagged and monitored -when the count reaches a threshold (the sampling period) and a valid op is -available. -
      • -
    • -Dispatched op-based selection counts dispatched macro-ops. -When the count reaches a threshold, the next valid op is tagged and monitored. -
      • -
    -
    -

    -In both cases, an IBS sample is generated only if the tagged op retires. -Thus, IBS op event information does not measure speculative execution activity. -The execution stages of the pipeline monitor the tagged macro-op. When the -tagged macro-op retires, a sampling interrupt is generated and an IBS op -sample is taken. An IBS op sample contains a timestamp, the identifier of -the interrupted process, the virtual address of the AMD64 instruction from -which the op was issued, and several event flags and values that describe -what happened when the macro-op executed. -

    -
    -

    -Enabling IBS profiling is done simply by specifying IBS performance events -through the "--event=" options. These events are listed in the -opcontrol --list-events. -

    - - - - -
    - 
    -opcontrol --event=IBS_FETCH_XXX:<count>:<um>:<kernel>:<user>
-opcontrol --event=IBS_OP_XXX:<count>:<um>:<kernel>:<user>
-
-Note: * All IBS fetch event must have the same event count and unitmask,
-        as do those for IBS op.

    6.8. IBM System z hardware sampling support

    -
    -
    -
    -

    -IBM System z provides a facility which does instruction sampling as -part of the CPU. This has great advantages over the timer based -sampling approach like better sampling resolution with less overhead -and the possibility to get samples within code sections where -interrupts are disabled (useful especially for Linux kernel code). -

    -

    Note

    Profiling with the instruction sampling facility is currently only supported -with legacy mode profiling (i.e., with opcontrol).
    -

    -A public description of the System z CPU-Measurement Facilities can be -found here: -The Load-Program-Parameter and CPU-Measurement Facilities -

    -

    -System z hardware sampling can be used for Linux instances in LPAR -mode. The hardware sampling support used by OProfile was introduced -for System z10 in October 2008. -

    -

    -To enable hardware sampling for an LPAR you must activate the LPAR -with authorization for basic sampling control. See the "Support -Element Operations Guide" for your mainframe system for more -information. -

    -

    -The hardware sampling facility can be enabled and disabled using the -event interface. A `virtual' counter 0 has been defined that only supports -a single event, HWSAMPLING. By default the HWSAMPLING event is -enabled on machines providing the facility. For both events only the -`count', `kernel' and `user' options are evaluated by the kernel -module. -

    -

    -The `count' value is the sampling rate as it is passed to the CPU -measurement facility. A sample will be taken by the hardware every -`count' cycles. Using low values here will quickly fill up the -sampling buffers and will generate CPU load on the OProfile daemon and -the kernel module being busy flushing the hardware buffers. This -might considerably impact the workload to be profiled. -

    -

    -The unit mask `um' is required to be zero. -

    -

    -The opcontrol tool provides a new option specific to System z -hardware sampling: -

    -
    -
      -
    • --s390hwsampbufsize="num": Number of 2MB areas -used per CPU for storing sample data. The best -size for the sample memory depends on the particular system and the -workload to be measured. Providing the sampler with too little memory -results in lost samples. Reserving too much system memory for the -sampler impacts the overall performance and, hence, also the workload -to be measured.
      • -
    -
    -

    -A special counter /dev/oprofile/timer is provided -by the kernel module allowing to switch back to timer mode sampling -dynamically. The TIMER event is limited to be used only with this -counter. The TIMER event can be specified using the ---event= as with every other event. -

    - - - - -
    - 
    opcontrol --event=TIMER:1
    -
    -

    -On z10 or later machines the default event is set to TIMER in case the -hardware sampling facility is not available. -

    -

    -Although required, the 'count' parameter of the TIMER event is -ignored. The value may eventually be used for timer based sampling -with a configurable sampling frequency, but this is currently not -supported. -

    -
    -
    -
    -
    -
    -

    6.9. Dangerous counter settings

    -
    -
    -
    -

    -OProfile is a low-level profiler which allows continuous profiling with a low-overhead cost. -When using OProfile legacy mode profiling, it may be possible to configure such a low a counter reset value -(i.e., high sampling rate) that the system can become overloaded with counter interrupts and your -system's responsiveness may be severely impacted. Whilst some validation is done on the count -values you pass to opcontrol with your event specification, it is not foolproof. -

    -
    -

    Note

    -

    -This can happen as follows: When the profiler count -reaches zero, an NMI handler is called which stores the sample values in an internal buffer, then resets the counter -to its original value. If the reset count you specified is very low, a pending NMI can be sent before the NMI handler has -completed. Due to the priority of the NMI, the pending interrupt is delivered immediately after -completion of the previous interrupt handler, and control never returns to other parts of the system. -If all processors are stuck in this mode, the system will appear to be frozen. -

    -
    -

    If this happens, it will be impossible to bring the system back to a workable state. -There is no way to provide real security against this happening, other than making sure to use a reasonable value -for the counter reset. For example, setting CPU_CLK_UNHALTED event type with a ridiculously low reset count (e.g. 500) -is likely to freeze the system. +The performance monitoring unit (PMU) for the IBM PowerPC 64-bit processors +consists of between 4 and 8 counters (depending on the model). Advanced features +such as instruction matching and thresholding are not supported by OProfile.

    -

    -In short : Don't try a foolish sample count value. Unfortunately the definition of a foolish value -is really dependent on the event type. If ever in doubt, post a message to

    -
    -

    .

    -

    -

    -

    Note

    -The scenario described above cannot occur if you use operf for profiling instead of -opcontrol, because the perf_events kernel subsystem automatically detects when performance monitor -interrupts are arriving at a dangerous level and will throttle back the sampling rate. -

When such a condition is signaled on an instruction, the front end of the machine is notified that it must restart, so no more instructions will be decoded from the current path. All instructions "older" than this one will be allowed to finish. This instruction and all "younger" instructions must be cleared, since they must not be allowed to complete. Essentially, the hardware waits until the problematic instruction is the oldest instruction in the machine. This means all older instructions are retired, and all pending stores (from older instructions) are completed. Then the new path of instructions from the front end are allowed to start into the machine. There are many conditions that might cause a machine clear (including the receipt of an interrupt, or a trap or a fault). All those conditions (including but not limited to MACHINE_CLEARS.MEMORY_ORDERING, MACHINE_CLEARS.SMC, and MACHINE_CLEARS.FP_ASSIST) are captured in the ANY event. In addition, some conditions can be specifically counted (i.e. SMC, MEMORY_ORDERING, FP_ASSIST).

This event can be used to identify if the machine is truly front-end bound. When this event occurs, it is an indication that the front-end of the machine is operating at less than its theoretical peak performance. Background: We can think of the processor pipeline as being divided into 2 broader parts: Front-end and Back-end. Front-end is responsible for fetching the instruction, decoding into micro-ops (uops) in machine understandable format and putting them into a micro-op queue to be consumed by back end. The back-end then takes these micro-ops, allocates the required resources. When all resources are ready, micro-ops are executed. If the back-end is not ready to accept micro-ops from the front-end, then we do not want to count these as front-end bottlenecks. However, whenever we have bottlenecks in the back-end, we will have allocation unit stalls and eventually forcing the front-end to wait until the back-end is ready to receive more UOPS. This event counts the cycles only when back-end is requesting more uops and front-end is not able to provide them. Some examples of conditions that cause front-end efficiencies are: Icache misses, ITLB misses, and decoder restrictions that limit the the front-end bandwidth. +name:rs_full_stall type:exclusive default:0x1f + 0x1f extra: all Counts the number of cycles the Alloc pipeline is stalled when any one of the RSs (IEC, FPC and MEC) is full.

+          
    
+This section describes in detail how ocount is used.
+Unless the --events option is specified, ocount will use
+the default event for your system. For most systems, the default event is some
+cycles-based event, assuming your processor type supports hardware performance
+counters. The event specification used for ocount is slightly
+different from that required for profiling -- a count value
+is not needed. You can see the event information for your CPU using ophelp.
+More information on event specification can be found at Section 3, “Specifying performance counter events”.
+
    
+

+          
    
+One and only one of these 5 run modes must be specified when you run ocount.
+If you run ocount using a run mode other than command [args], press Ctrl-c
+to stop it when finished counting (e.g., when the monitored process ends). If you background ocount
+(i.e., with ’&’) while using one these run modes, you must stop it in a controlled manner so that
+the data collection process can be shut down cleanly and final results can be displayed.
+Use kill -SIGINT <ocount-PID> for this purpose.

 Many CPUs provide "performance counters", hardware registers that can count "events"; for example,
-cache misses, or CPU cycles. OProfile provides profiles of code based on the number of these occurring events:
+cache misses, or CPU cycles. OProfile can collect profiles of code based on the number of these occurring events:
 repeatedly, every time a certain (configurable) number of events has occurred, the PC value is recorded.
-This information is aggregated into profiles for each binary image.
-
-Some hardware setups do not allow OProfile to use performance counters: in these cases, no
-events are available so OProfile operates in timer mode, as described in later chapters. Timer
-mode is only available in "legacy mode" (see ).
-
+This information is aggregated into profiles for each binary image.  Alternatively, OProfile's event counting
+tool can collect simple raw event counts.
 
-OProfile legacy mode
-"Legacy" OProfile consists of the opcontrol shell script, the oprofiled daemon, and several post-processing tools (e.g.,
-opreport). The opcontrol script is used for configuring, starting, and stopping a profiling session. An OProfile
-kernel driver (usually built as a kernel module) is used for collecting samples, which are then recorded into sample files by
-oprofiled. Using OProfile in "legacy mode" requires root user authority since the profiling is done on a system-wide basis, which may
-(if misused) cause adverse effects to the system.
-
-Profiling setup parameters that you specify using opcontrol are cached in /root/.oprofile/daemonrc.
-Subsequent runs of opcontrol --start will continue to use these cached values until you
-override them with new values.
-
+OProfile legacy profiling mode
+Prior to release 1.0, OProfile included a profiling tool consisting of the opcontrol shell script, the oprofiled daemon,
+and the attendant oprofile kernel driver. This "legacy profiler" was deprecated in release 0.9.8 with the introduction of
+the operf profiling tool (see ). Some older architectures/platforms
+do not support the use of operf. For those cases, oprofile users should install release 0.9.9, which is the
+last release to include the legacy profiler.
 
 
-OProfile perf_events mode
-As of release 0.9.8, OProfile now includes the ability to profile a single process versus the system-wide technique
-of legacy OProfile. With this new technique, the operf program is used to control profiling instead of the
-opcontrol script and oprofiled daemon of leagacy mode. Also, operf does not require the
-special OProfile kernel driver that legacy mode does; instead, it interfaces with the kernel to collect samples via the Linux Kernel
-Performance Events Subsystem (hereafter referred to as "perf_events"). Using operf to profile a single
-process can be done as a normal user; however, root authority is required to run operf in system-wide
-profiling mode.
-
-Note 1
-The same OProfile post-processing tools are used whether you collect your profile with operf or opcontrol.

+OProfile perf_events profiling mode

+OProfile has the ability to profile a single process or every currently running process (i.e., system-wide)

+
+
+OProfile event counting mode
+OProfile provides the ocount tool for
+collecting raw event counts on a per-application, per-process, per-cpu, or system-wide basis.  Unlike the
+profiling tools, post-processing of the data collected is not necessary -- the data is displayed in the
+output of ocount.  A common use case for event counting tools is when performance analysts
+want to determine the CPI (cycles per instruction) for an application. High CPI implies possible stalls,
+and many architectures provide events that give detailed information about the different types of stalls.
+The events provided are architecture-specific, so we refer the reader to the hardware manuals available for
+the processor type being used.
