What do you think about this? Do we also want to make the disabled flag per
CPU? Or how should we deal with a different number of C states per CPU?
Hi Peter,
yes, that could makes sense. But in most of the architecture, this is
not needed, so duplicating the state's array and latencies is unneeded
memory consumption.
Maybe we can look for a COW approach, similar to what is done for the
nsproxy structure, no ?
