Core scheduling is a recent innovation in newer kernels to help run certain untrusted compute workloads more safely in the face of vulnerabilities like Spectre. In short: it lets processes assign a unique "cookie" to some group of processes to indicate they are allowed to be scheduled together on the same SMT-capable core. This helps mitigate attacks that rely on observing usage of CPU execution units by cohabitated threads. Some extra details are available via Linux Weekly News: "Core scheduling lands in 5.14", https://lwn.net/Articles/861251/ Signed-off-by: Austin Seipp <aseipp@pobox.com> |
