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