InZVM20.01.0.0,
-XX:+FalconCompensateForIntelMCUForErratumSKX102is an off-by-default option and introduces a nop padding based mitigation for performance regressions seen on some systems following Intel’s microcode updates in response to errata SKX102. This option is expected to become the default in a future Zing release. If enabled, nop padding will be used to align affected branches on systems with the microcode update applied.For testing purposes, the flag
-XX:+ForceFalconCompensateForIntelMCUForErratumSKX102is also provided. This can be used to force the generation of nop padded code on unaffected systems for performance validation.
