perf is a userspace interface to the kernel's perf events. Performance
|
|
counters are CPU hardware registers that count hardware events
|
|
such as instructions executed, cache-misses suffered, or branches
|
|
mispredicted. They form a basis for profiling applications to trace
|
|
dynamic control flow and identify hotspots.
|
|
|
|
Optional dependencies: audit, numactl
|
|
|
|
Please note that this build doesn't have any sources in the .info
|
|
file, as the sources are already part of the Slackware kernel-source
|
|
package. Your running kernel's version should match the kernel-source
|
|
version. If it doesn't:
|
|
|
|
- If your kernel source is located in /usr/src/linux-$VERSION, you
|
|
can export KERNEL=<version> in the script's environment. Example:
|
|
|
|
export KERNEL=5.11.17
|
|
|
|
- If your kernel source is somewhere else, you can export
|
|
KERNEL=</path/to/source>. Example:
|
|
|
|
export KERNEL=/home/myuser/kernels/linux-5.11.17
|
|
|
|
Please note that the package's version number will match the version
|
|
of the kernel source, *not* necessarily what's in the perf.info file.
