NYLUG Presents: Andrea Arcangeli and Jon Masters -on- Speculation out of control, taming CPU bugs
Channel: NYLUG
Date: 2018-05-03

Andrea and Jon have worked for months to mitigate the recently publicized Meltdown and Spectre bugs. They will provide a brief introduction to the side channel problems affecting all high performance modern CPU architectures. Then an overview about how these issues have been solved on the x86_64 Architecture in the Linux kernel, explaining what are the technical options and which choices have been made by the upstream kernel community as well as some downstream vendors. In addition, Andrea will provide practical advice about what tradeoffs can be selected at runtime and build time as well as explain the various performance issues that may affect running workloads.
