From: Frank Zhu <[email protected]> Update the kvm_is_tdp_enabled() function to include Zhaoxin CPUs when checking for EPT (Extended Page Tables) support. This ensures that ZX CPUs use the appropriate TDP (Two-Dimensional Paging) parameter check, similar to Intel CPUs. The change modifies the condition to check for both Intel and ZX CPUs before querying the EPT parameter, maintaining compatibility with existing Intel systems while extending support to ZX CPU systems.
