You can see an error message that says the Ubuntu kernel is profiled. There are several ways to solve this problem. We will discuss this shortly.
NAME
oprofile is a new statistical profiler for Linux systems capable of profiling all running code low overhead costs; Your post-profiling toolbox as well simple tool for counting events
OProfile is usually a complete set of profiles for systems running Linux 2.6.31 and newer. OProfile uses one of the hardware success counters provided by Intel, AMD and others. Processors. OProfile can profile the best program, the best technology chosen, or the entire system. OProfile can also be used to collect the total number of events in an application, process, or system level. For more information on using OProfile, please read this HTML documentation at SEE. listedSAME.
WORK
operf is a profiler performance resource for Linux.
ACCOUNT
ocount is a case counting tool for Linux.
REPORT
opreport provides summary profile data based on images and symbols of the entire system or a stunning subset binary images.
OPEN
opannotate get can annotate the source or be used in a combination of source and assembler output.
ORCH
oparchive oprofile creates an archive for offline analysis
OPGPROF
opgprof will most likely create a gprof-formatted profile for a single binary.
PROFILE CHARACTERISTICS
Various additional profile descriptions of post-profiling tools can be used. A Profile criteria are a combination of the options listed below. (Mark: Including part of the descriptive specification between curly braces is most likely used for differentials. Backgrounds with opreport, but they really need to be surrounded by spaces.) Archive: Aphiv The path to the archive for verification generated by oparchive Session: List of Sessions A comma-separated list of session domain names to resolve. The absence of such a mark, in contrast to almost different, “previous session” methods equivalent to specifying “Session: in progress”. Session Exception: Session List A comma-separated list of sessions to exclude positively. Image: image list A comma-separated list of resolved names. Each find can be a relative path glob type name or full path, eg. opreport ‘image: / usr / bin / operf, * op *,. / oprofpp ‘ image-exclude: image list Like, but image :, the corresponding images are excluded. lib-image: list of images The same is mostly due to the image: but only for videos that target a specific meaningful binary image (i.e. great app). This only makes sense if you are using –separate. This includes kernel and kernel modules when using –separate = kernel. lib-image-exclude: image list Similar to, but matches your current images are excluded. Event: Event name The symbolic name of the event to be linked, eg. Event: DATA_MEM_REFS. count: number of events The celebration is part of the game, for example event: DATA_MEM_REFS counts: 30,000. unit-mask: Mask value The unit cost of the nasal and mouth mask of the event being completed, for example, a unit mask: 1. Processor: Cpulist Consider only profiles based on the numbered CPU shown (starting at zero). So to speak only useful when using a CPU allocation profile. tgid: pid list Consider only the profiles for the specified task groups. If the program definitely doesn’t use Threads, the actual task group ID for the entire operation matches its ID history. This option directly conforms to the concept of POSIX Thread a trust group. It is only useful and interesting when you use itSeparation of data by processes. tid: popup list Think about profiles for these chats. If you are using modern thread libraries, each bit of a thread in a process has a common task group id and different threads identifiers. You can of course use this option in conjunction with tgid: to limit the positives separate streams throughout the operation. It is only effective when used by the process. Report the separation.
