6# must be amd-pstate.
7# (1) It can help all users to verify their processor support

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.
