From 61ad65d0f01d928b259effb57e2a356f3e3dac03 Mon Sep 17 00:00:00 2001 From: Robert Hoo Date: Tue, 22 Sep 2020 15:14:14 +0800 Subject: cpu: Introduce CPU model deprecation API Implement the ability of marking some versions deprecated. When that CPU model is chosen, print a warning. The warning message can be customized, e.g. suggesting an alternative CPU model to be used instead. The deprecation message will be printed by x86_cpu_list_entry(), e.g. '-cpu help'. QMP command 'query-cpu-definitions' will return a bool value indicating the deprecation status.
