https://www.amd.com/en/corporate/speculative-execution reports. . . For the Bounds Check Bypass Spectre variant (#1): Resolved by software / OS updates to be made available by system vendors and manufacturers. Negligible performance impact expected. For the Branch Target Injection Spectre variant (#2): Differences in AMD architecture mean there is a near zero risk of exploitation of this variant. Vulnerability to Variant 2 has not been demonstrated on AMD processors to date. For the Rogue Data Cache Load Meltdown variant (#3): Zero AMD vulnerability due to AMD architecture differences. How long #2 will have a "has not been demonstrated" status is yet to be seen. === Mark Millard markmi at dsl-only.net _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
