[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH RFC v13 01/20] Allow vmx_update_debug_state to be called when v!=current
Removing the assert allows the PVH code to call this during vmcs construction in a later patch, making the code more robust by removing duplicate code.
