In linux 5.14 and hopefully some backports, core scheduling allows processes to be co scheduled within the same domain on SMT enabled systems. The containerd impl sets the core sched domain when launching a shim. This allows a clean way for each shim(container/pod) to be in its own domain and any additional containers, (v2 pods) be be launched with the same domain as well as any exec'd process added to the container. kernel docs: https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/core-scheduling.html Signed-off-by: Michael Crosby <michael@thepasture.io>
