Latest Patents
One of his latest patents is titled "Instruction processing in higher level virtual machines by a real machine." This patent discloses a method for processing instructions in higher-level virtual machines using a 370-XA mode real machine. The real machine and a low-level virtual machine each execute a version of the real machine's system control program. The low-level virtual machine issues a privileged instruction that is simulated by the real machine, indicating that instructions in a higher-level virtual machine are to be processed. A shadow state description is created and used by the privileged instruction for describing the higher-level virtual machine directly to the real machine. Additionally, shadow address translation tables are created to facilitate address translation from a higher-level virtual machine to the real machine.
Another significant patent is "Selective guest system purge control." This invention enables address translations for a virtual machine in the translation lookaside buffer (TLB) of a CPU to be retained from exiting a start interpretive execution instruction to the next entry for the same guest. Conditions are defined to determine when guest TLB entries must be invalidated, ensuring that the integrity of the system is maintained.
