[PATCH v4 3/7] x86/resctrl: Change monitor code to use rdt_mondomain

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A few functions need to be duplicated to provide versions to
operate on control and monitor domains respectively. But most
of the changes are just fixing argument and return value types.
