Patent number: 12253958Abstract: This disclosure is directed to a system for address mapping and translation protection. In one embodiment, processing circuitry may include a virtual machine manager (VMM) to control specific guest linear address (GLA) translations. Control may be implemented in a performance sensitive and secure manner, and may be capable of improving performance for critical linear address page walks over legacy operation by removing some or all of the cost of page walking extended page tables (EPTs) for critical mappings. Alone or in combination with the above, certain portions of a page table structure may be selectively made immutable by a VMM or early boot process using a sub-page policy (SPP). For example, SPP may enable non-volatile kernel and/or user space code and data virtual-to-physical memory mappings to be made immutable (e.g., non-writable) while allowing for modifications to non-protected portions of the OS paging structures and particularly the user space.Type: GrantFiled: October 7, 2021Date of Patent: March 18, 2025Assignee: Intel CorporationInventors: Ravi L.

Patent number: 11377364Abstract: A process for preparing doped-lithium lanthanum zirconium oxide (doped-LLZO) is described herein. The method involves dry doping of a co-precipitated lanthanum zirconium oxide (LZO) precursor. Dry doping is a process in which a dry powdered dopant is ground and mixed with a pre-prepared co-precipitated LZO precursor and a lithium salt to provide a LLZO precursor composition, which is subsequently calcined to form a doped-LLZO. The process described herein comprises calcining a dry, powdered (e.g., micron, sub-micron or nano-powdered) mixture of a co-precipitated LZO precursor, a dopant salt or oxide, and a lithium salt under an oxygen-containing atmosphere at a temperature in the range of about 500 to about 1100° C., and recovering the doped-LLZO after calcining.Type: GrantFiled: December 26, 2019Date of Patent: July 5, 2022Assignee: UCHICAGO ARGONNE, LLCInventors: Jessica L.
