4# amd-pstate-ut is a test module for testing the amd-pstate driver.
5# It can only run on x86 architectures and current cpufreq driver
6# must be amd-pstate.
7# (1) It can help all users to verify their processor support
8# (SBIOS/Firmware or Hardware).
9# (2) Kernel can have a basic function test to avoid the kernel
10# regression during the update.
11# (3) We can introduce more functional or performance tests to align
12# the result together, it will benefit power and performance scale optimization.
