But why? It’s not standard capability? In my understanding, standard cap should have the same offset definitions for all devices. > As of now it is not exposed to user. Bruce's test was on 6.2 generic kernel > (6.2.0-36-generic) Will kernel plan to support that? I can see the related work was done by Intel but somehow it’s not merged into kernel. Could you give more information on this? If kernel does not want this to be exposed, it means userspace should not access this. No? /Chenbo
