Add CPUID controller to control the user's settings for CPUID leaves, including the management of the configurable leaves, the validity checking and adjustment of input values. Signed-off-by: Wenchao Wang <wenchao.wang@intel.com>
Optimize host supported features cache algorithm during HAXM initialization. * Simplify the storage type for both host and guest supported features * Improve the calculation method of host supported features to be more efficient Signed-off-by: Wenchao Wang <wenchao.wang@intel.com>
Add CPUID manager to manage the supported guest CPUID instructions. For the leaves in the manager list, if the execution function is specified, the return values of the host CPUID instruction will be overwritten; If not specified, the host values will be returned directly. For the leaves not in the manager list, it will return that those CPUID instructions are not supported. Signed-off-by: Wenchao Wang <wenchao.wang@intel.com>
Cache the supported guest CPUID instruction values in the initialization phase to avoid repeated calculations each time a guest CPUID instruction is executed. The supported guest CPUID leaves are managed by the CPUID manager, and the cache memory size is dynamically calculated. When setting the CPUID values, modify the cached values directly.

Enable support for guest CPUID instructions CPUID.15H and CPUID.16H. * Add CPUID.15H and CPUID.16H into CPUID manager as the supported guest CPUID instructions * Add CPUID.15H and CPUID.16H into CPUID controller to allow user to set their values * Adjust maximum return value of basic CPUID information to 0x16 Signed-off-by: Wenchao Wang <wenchao.wang@intel.com>
