If anyone has any objections, please let me know. ------------------ From: Zhang Rui [ Upstream commit 2c3aedd9db6295619d21e50ad29efda614023bf1 ] For Alderlake, the spec changes after the patch submitted and PC7/PC9 are removed. Raptorlake and Meteorlake, which copy the Alderlake cstate PMU, also don't have PC7/PC9. Remove PC7/PC9 support for Alderlake/Raptorlake/Meteorlake.
