  • APPARATUSES AND METHODS FOR SPECULATIVE EXECUTION SIDE CHANNEL MITIGATION
    Publication number: 20230342156
    Abstract: Methods and apparatuses relating to mitigations for speculative execution side channels are described. Speculative execution hardware and environments that utilize the mitigations are also described. For example, three indirect branch control mechanisms and their associated hardware are discussed herein: (i) indirect branch restricted speculation (IBRS) to restrict speculation of indirect branches, (ii) single thread indirect branch predictors (STIBP) to prevent indirect branch predictions from being controlled by a sibling thread, and (iii) indirect branch predictor barrier (IBPB) to prevent indirect branch predictions after the barrier from being controlled by software executed before the barrier.
    Type: Application
    Filed: April 24, 2023
    Publication date: October 26, 2023
    Inventors: Jason W. Brandt, Deepak K. Gupta, Rodrigo Branco, Joseph Nuzman, Robert S. Chappell, Sergiu Ghetie, Wojciech Powiertowski, Jared W. Stark, IV, Ariel Sabba, Scott J. Cape, Hisham Shafi, Lihu Rappoport, Yair Berger, Scott P. Bobholz, Gilad Holzstein, Sagar V. Dalvi, Yogesh Bijlani
