# Add local patches below here based on {version_pure}:
#
# Example: for kernel version 6.14.* {version_pure} = 614 and local patches on
# top of this (that will be in 6.15) should be numbered 6140-6149. Unlike SLE
# we only carry a handful of local patches in Factory.
#
# This avoids the perf build breaking when the kernel version in Factory
# asynchronously updates.

%description
This package provides a userspace tool 'perf', which monitors performance for
either unmodified binaries or the entire system. It requires a Linux kernel
which includes the Performance Counters for Linux (PCL) subsystem (>= 2.6.31).
This subsystem utilizes the Performance Monitoring Unit (PMU) / hardware
counters of the underlying cpu architecture (if supported).
