2.10 Profiling the kernel. There are several facilities to see where the kernel spends its resources. A simple one is the profiling function, that stores the current EIP (instruction pointer) at each clock tick. Boot the kernel with command line option profile=2 (or some other number instead of 2).

Sep 14, 2017 · This article will introduce the GPU In-kernel Profiling feature in Intel® VTune™ Amplifier, using one of the OpenCL™ samples from the Intel® SDK for OpenCL™ Applications. We will cover a brief introduction to OpenCL and the Intel SDK for OpenCL Applications, as well as walking through the process of profiling an OpenCL application using VTune Amplifier's GPU profiling features.

(i.e., the ULE scheduler), enabling performance sampling support (PmcStat), and enabling Kernel lock profiling support. To build a new Kernel including a new compile-time enabled feature, a new Kernel profile must be created. The Kernel profile is the compile-time configuration file. …

Your kernel is likely to support halting the processor when a CPU is idle. As the typical hardware events like CPU_CLK_UNHALTED do not count when the CPU is halted, the kernel profile will not reflect the actual amount of time spent idle. You can change this behaviour by booting with the idle=poll option, which uses a different idle routine. This will appear as poll_idle() in your kernel profile.

Linux kernel profiling features May 12, 2014 Intro. ... And in addition to that perf included tracepoint support via ftrace. To access perf_events there is a special syscall perf_event_open. You are passing the type of event (hardware, kernel, tracepoint) and so-called config, where you specify what exactly you want depending on type. ...

Using gcov with the Linux kernel¶. gcov profiling kernel support enables the use of GCC’s coverage testing tool gcov with the Linux kernel. Coverage data of a running kernel is exported in gcov-compatible format via the “gcov” debugfs directory.
